9ce2504554 fix(node:http): unref poll_ref on WebSocket upgrade to prevent CPU spin (#24271)
## Summary

Fixes 100% CPU usage on idle WebSocket servers between bun-v1.2.23 and
bun-v1.3.0.

Many users reported WebSocket server CPU usage jumping to 100% on idle
connections after upgrading to v1.3.0. Investigation revealed a missing
`poll_ref.unref()` call in the WebSocket upgrade path.

## Root Cause

In commit 625e537f5d (#23348), the `OnBeforeOpen` callback mechanism was
removed as part of refactoring the WebSocket upgrade process. However,
this callback contained a critical cleanup step:

```zig
defer ctx.this.poll_ref.unref(ctx.globalObject.bunVM());
```

When a `NodeHTTPResponse` is created, `poll_ref.ref()` is called (line
314) to keep the event loop alive while handling the HTTP request. After
a WebSocket upgrade, the HTTP response object is no longer relevant and
its `poll_ref` must be unref'd to indicate the request processing is
complete.

Without this unref, the event loop maintains an active reference even
after the upgrade completes, causing the CPU to spin at 100% waiting for
events on what should be an idle connection.

## Changes

- Added `poll_ref.unref()` call in `NodeHTTPResponse.upgrade()` after
setting the `upgraded` flag
- Added regression test to verify event loop properly exits after
WebSocket upgrade

## Test Plan

- [x] Code compiles successfully
- [x] Existing WebSocket tests pass
- [x] Manual testing confirms CPU usage returns to normal on idle
WebSocket connections

## Related Issues

Fixes issue reported by users between bun-v1.2.23 and bun-v1.3.0
regarding 100% CPU usage on idle WebSocket servers.

528620e9ae Add postinstall optimizer with native binlink support and script skipping (#24283)
## Summary

This PR introduces a new postinstall optimization system that
significantly reduces the need to run lifecycle scripts for certain
packages by intelligently handling their requirements at install time.

## Key Features

### 1. Native Binlink Optimization

When packages like `esbuild` ship platform-specific binaries as optional
dependencies, we now:
- Detect the native binlink pattern (enabled by default for `esbuild`)
- Find the matching platform-specific dependency based on target CPU/OS
- Link binaries directly from the platform-specific package (e.g.,
`@esbuild/darwin-arm64`)
- Fall back gracefully if the platform-specific package isn't found

**Result**: No postinstall scripts needed for esbuild and similar
packages.

### 2. Lifecycle Script Skipping

For packages like `sharp` that run heavy postinstall scripts:
- Skip lifecycle scripts entirely (enabled by default for `sharp`)
- Prevents downloading large binaries or compiling native code
unnecessarily
- Reduces install time and potential failures in restricted environments

## Configuration

Both features can be configured via `package.json`:

```json
{
  "nativeDependencies": ["esbuild", "my-custom-package"],
  "ignoreScripts": ["sharp", "another-package"]
}
```

Set to empty arrays to disable defaults:
```json
{
  "nativeDependencies": [],
  "ignoreScripts": []
}
```

Environment variable overrides:
- `BUN_FEATURE_FLAG_DISABLE_NATIVE_DEPENDENCY_LINKER=1` - disable native
binlink
- `BUN_FEATURE_FLAG_DISABLE_IGNORE_SCRIPTS=1` - disable script ignoring

## Implementation Details

### Core Components

- **`postinstall_optimizer.zig`**: New file containing the optimizer
logic
- `PostinstallOptimizer` enum with `native_binlink` and `ignore`
variants
  - `List` type to track optimization strategies per package hash
  - Defaults for `esbuild` (native binlink) and `sharp` (ignore)
  
- **`Bin.Linker` changes**: Extended to support separate target paths
  - `target_node_modules_path`: Where to find the actual binary
  - `target_package_name`: Name of the package containing the binary
  - Fallback logic when native binlink optimization fails

### Modified Components

- **PackageInstaller.zig**: Checks optimizer before:
  - Enqueueing lifecycle scripts
  - Linking binaries (with platform-specific package resolution)
  
- **isolated_install/Installer.zig**: Similar checks for isolated linker
mode
  - `maybeReplaceNodeModulesPath()` resolves platform-specific packages
  - Retry logic without optimization on failure

- **Lockfile**: Added `postinstall_optimizer` field to persist
configuration

## Changes Included

- Updated `esbuild` from 0.21.5 to 0.25.11 (testing with latest)
- VS Code launch config updates for debugging install with new flags
- New feature flags in `env_var.zig`

## Test Plan

- [x] Existing install tests pass
- [ ] Test esbuild install without postinstall scripts running
- [ ] Test sharp install with scripts skipped
- [ ] Test custom package.json configuration
- [ ] Test fallback when platform-specific package not found
- [ ] Test feature flag overrides

7197fb1f04 Fix Module._resolveFilename to pass options.paths to overridden functions (#24325)
Fixes Next.js 16 + React Compiler build failure when using Bun runtime.

## Issue
When `Module._resolveFilename` was overridden (e.g., by Next.js's
require-hook), Bun was not passing the `options` parameter (which
contains `paths`) to the override function. This caused resolution
failures when the override tried to use custom resolution paths.

Additionally, when `Module._resolveFilename` was called directly with
`options.paths`, Bun was ignoring the paths parameter and using default
resolution.

## Root Causes
1. In `ImportMetaObject.cpp`, when calling an overridden
`_resolveFilename` function, the options object with paths was not being
passed as the 4th argument.

2. In `NodeModuleModule.cpp`, `jsFunctionResolveFileName` was calling
`Bun__resolveSync` without extracting and using the `options.paths`
parameter.

## Solution
1. In `ImportMetaObject.cpp`: When `userPathList` is provided, construct
an options object with `{paths: userPathList}` and pass it as the 4th
argument to the overridden `_resolveFilename` function.

2. In `NodeModuleModule.cpp`: Extract `options.paths` from the 4th
argument and call `Bun__resolveSyncWithPaths` when paths are provided,
instead of always using `Bun__resolveSync`.

## Reproduction
Before this fix, running:
```bash
bun --bun next build --turbopack
```
on a Next.js 16 app with React Compiler enabled would fail with:
```
Cannot find module './node_modules/babel-plugin-react-compiler'
```

## Testing
- Added comprehensive tests for `Module._resolveFilename` with
`options.paths`
- Verified Next.js 16 + React Compiler + Turbopack builds successfully
with Bun
- All 5 new tests pass with the fix, 3 fail without it
- All existing tests continue to pass

## Files Changed
- `src/bun.js/bindings/ImportMetaObject.cpp` - Pass options to override
- `src/bun.js/modules/NodeModuleModule.cpp` - Handle options.paths in
_resolveFilename
- `test/js/node/module/module-resolve-filename-paths.test.js` - New test
suite

946470dcd7 Refactor: move FetchTasklet to separate file (#24330)
## Summary

Extract `FetchTasklet` struct from `src/bun.js/webcore/fetch.zig` into
its own file at `src/bun.js/webcore/fetch/FetchTasklet.zig` to improve
code organization and modularity.

## Changes

- Moved `FetchTasklet` struct definition (1336 lines) to new file
`src/bun.js/webcore/fetch/FetchTasklet.zig`
- Added all necessary imports to the new file
- Updated `fetch.zig` line 61 to import `FetchTasklet` from the new
location: `pub const FetchTasklet =
@import("./fetch/FetchTasklet.zig").FetchTasklet;`
- Verified compilation succeeds with `bun bd`

## Impact

- No functional changes - this is a pure refactoring
- Improves code organization by separating the large `FetchTasklet`
implementation
- Makes the codebase more maintainable and easier to navigate
- Reduces `fetch.zig` from 2768 lines to 1433 lines

## Test plan

- [x] Built successfully with `bun bd`
- [x] No changes to functionality - pure code organization refactor

bdaab89253 Fix bun update --interactive not installing packages (#24280)
## Summary

Fixes a bug where `bun update --interactive` only updated `package.json`
but didn't actually install the updated packages. Users had to manually
run `bun install` afterwards.

## Root Cause

The bug was in `savePackageJson()` in
`src/cli/update_interactive_command.zig`:

1. The function wrote the updated `package.json` to disk
2. But it **didn't update the in-memory cache**
(`WorkspacePackageJSONCache`)
3. When `installWithManager()` ran, it called `getWithPath()` which
returned the **stale cached version**
4. So the installation proceeded with the old dependencies

## The Fix

Update the cache entry after writing to disk (line 116):
```zig
package_json.*.source.contents = new_package_json_source;
```

This matches the behavior in `updatePackageJSONAndInstall.zig` line 269.

## Test Plan

Added comprehensive regression tests in
`test/cli/update_interactive_install.test.ts`:
-  Verifies that `package.json` is updated
-  Verifies that `node_modules` is updated (this was failing before the
fix)
-  Tests both normal update and `--latest` flag
-  Compares installed version to confirm packages were actually
installed

Run tests with:
```bash
bun bd test test/cli/update_interactive_install.test.ts
```

39c43170e6 Add ServerWebSocket.subscriptions getter (#24299)
## Summary

Adds a `subscriptions` getter to `ServerWebSocket` that returns an array
of all topics the WebSocket is currently subscribed to.

## Implementation

- Added `getTopicsCount()` and `iterateTopics()` helpers to uWS
WebSocket
- Implemented C++ function `uws_ws_get_topics_as_js_array` that:
  - Uses `JSC::MarkedArgumentBuffer` to protect values from GC
  - Constructs JSArray directly in C++ for efficiency
  - Uses template pattern for SSL/TCP variants
  - Properly handles iterator locks with explicit scopes
- Exposed as `subscriptions` getter property on ServerWebSocket
- Returns empty array when WebSocket is closed (not null)

## API

```typescript
const server = Bun.serve({
  websocket: {
    open(ws) {
      ws.subscribe("chat");
      ws.subscribe("notifications");
      console.log(ws.subscriptions); // ["chat", "notifications"]
      
      ws.unsubscribe("chat");
      console.log(ws.subscriptions); // ["notifications"]
    }
  }
});
```

## Test Coverage

Added 5 comprehensive test cases covering:
- Basic subscription/unsubscription flow
- All subscriptions removed
- Behavior after WebSocket close
- Duplicate subscriptions (should only appear once)
- Multiple subscribe/unsubscribe cycles

All tests pass with 24 assertions.

f770b1b1c7 fix(install): fix optional peer resolving (#24272)
### What does this PR do?
Allows optional peers to resolve to package if possible.

Optional peers aren't auto-installed, but they should still be given a
chance to resolve. If they're always left unresolved it's possible for
multiple dependencies on the same package to result in different peer
resolutions when they should be the same. For example, this bug this
could cause monorepos using elysia to have corrupt node_modules because
there might be more than one copy of elysia in `node_modules/.bun` (or
more than the expected number of copies).

fixes #23725
most likely fixes #23895

### How did you verify your code works?

previously trigger this bug.

## Summary by CodeRabbit

* **New Features**
* Improved resolution of optional peer dependencies during isolated
installations, with better propagation across package hierarchies.

* **Tests**
* Added comprehensive test suite covering optional peer dependency
scenarios in isolated workspaces.
* Added test fixtures for packages with peer and optional peer
dependencies.
* Enhanced lockfile migration test verification using snapshot-based
assertions.

a912eca96a Add event loop architecture documentation (#24300)
## Summary

Adds comprehensive documentation explaining how Bun's event loop works,
including task draining, microtasks, process.nextTick, and I/O polling
integration.

## What does this document?

- **Task draining algorithm**: Shows the exact flow for processing each
task (run → release weak refs → drain microtasks → deferred tasks)
- **Process.nextTick ordering**: Explains batching behavior - all
nextTick callbacks in current batch run, then microtasks drain
- **Microtask integration**: How JavaScriptCore's microtask queue and
Bun's nextTick queue interact
- **I/O polling**: How uSockets epoll/kqueue events integrate with the
event loop
- **Timer ordering**: Why setImmediate runs before setTimeout
- **Enter/Exit mechanism**: How the counter prevents excessive microtask
draining

## Visual aids

Includes ASCII flowcharts showing:
- Main tick flow
- autoTick flow (with I/O polling)
- Per-task draining sequence

## Code references

All explanations include specific file paths and line numbers for
verification:
- `src/bun.js/event_loop/Task.zig`
- `src/bun.js/event_loop.zig`
- `src/bun.js/bindings/ZigGlobalObject.cpp`
- `src/js/builtins/ProcessObjectInternals.ts`
- `packages/bun-usockets/src/eventing/epoll_kqueue.c`

## Examples

Includes JavaScript examples demonstrating:
- nextTick vs Promise ordering
- Batching behavior when nextTick callbacks schedule more nextTicks
- setImmediate vs setTimeout ordering

28be8a9915 fix(NAPI): empty input napi_create_external_buffer (#24293)
### What does this PR do?
If the input was empty `ArrayBuffer::createFromBytes` would create a
buffer that `JSUint8Array::create` would see as detached, so it would
throw an exception. This would likely cause crashes in `node-addon-api`
because finalize data is freed if `napi_create_external_buffer` fails,
and we already setup the finalizer.

7c9e8a2b10 Remove MemoryReportingAllocator (#24251)
## Summary

Removes the `MemoryReportingAllocator` wrapper and simplifies
`fetch.zig` to use `bun.default_allocator` directly. The
`MemoryReportingAllocator` was wrapping `bun.default_allocator` to track
memory usage for reporting to the VM, but this added unnecessary
complexity and indirection without meaningful benefit.

## Changes

**Deleted:**
- `src/allocators/MemoryReportingAllocator.zig` (96 lines)

**Modified `src/bun.js/webcore/fetch.zig`:**
- Removed `memory_reporter: *bun.MemoryReportingAllocator` field from
`FetchTasklet` struct
- Removed `memory_reporter: *bun.MemoryReportingAllocator` field from
`FetchOptions` struct
- Replaced all `this.memory_reporter.allocator()` calls with
`bun.default_allocator`
- Removed all `this.memory_reporter.discard()` calls (no longer needed)
- Simplified `fetch()` function by removing memory reporter
allocation/wrapping/cleanup code
- Updated `deinit()` and `clearData()` to use `bun.default_allocator`
directly

**Cleanup:**
- Removed `MemoryReportingAllocator` export from `src/allocators.zig`
- Removed `MemoryReportingAllocator` export from `src/bun.zig`
- Removed `bun.MemoryReportingAllocator.isInstance()` check from
`src/safety/alloc.zig`

## Testing

-  Builds successfully with `bun bd`
- All fetch operations now use `bun.default_allocator` directly

## Impact

- **Net -116 lines** of code
- Eliminates allocator wrapper overhead in fetch operations
- Simplifies memory management code
- No functional changes to fetch behavior

## Summary

Updated all 49 usages of `Output.enable_ansi_colors` to properly check
either `Output.enable_ansi_colors_stdout` or
`Output.enable_ansi_colors_stderr` based on their output destination.

This prevents bugs where ANSI colors are checked against the wrong
stream (e.g., checking stdout colors when writing to stderr).

## Changes

### Added
- `Output.enable_ansi_colors` now a `@compileError` to prevent future
misuse with helpful error message directing to correct variants

### Deleted
- `Output.isEmojiEnabled()` - replaced all usages with
`enable_ansi_colors_stderr` (all were error/progress output)
- `Output.prettyWithPrinterFn()` - removed unused dead code

### Updated by Output Destination

**Stderr (error/diagnostic output):**
- logger.zig: Log messages and errors
- crash_handler.zig: Crash reports and stack traces (10 instances)
- PackageInstaller.zig: Error messages from lifecycle scripts (3
instances)
- JSValue.zig: Test expectation error messages
- JSGlobalObject.zig: Exception throwing
- pack_command.zig: Progress indicators
- VirtualMachine.zig: Exception printing (2 instances)
- Test expect files: Test failure messages and diffs (10 instances)
- diff_format.zig: Test diff output
- ProgressStrings.zig: Package manager progress emojis (6 functions)
- security_scanner.zig: Security scan progress emoji
- output.zig: panic(), resetTerminal()

**Stdout (primary output/interactive UI):**
- hot_reloader.zig: Terminal clearing on reload
- Version.zig: Version diff formatting
- install_with_manager.zig: Package installation tree
- update_interactive_command.zig: Interactive update UI (2 instances)
- init_command.zig: Interactive radio buttons
- create_command.zig: Template creation output (2 instances)
- outdated_command.zig: Outdated packages table
- publish_command.zig: Box drawing characters (6 instances)

**Backward Compatible:**
- BunObject.zig: `Bun.enableANSIColors` property returns `(stdout ||
stderr)` to maintain compatibility
- fmt.zig: Removed unused `.default` field from Options struct

## Test Plan

-  All changes compile successfully with `bun run zig:check`
-  Verified all 49 usages have been updated to appropriate variant
-  Verified no remaining references to deprecated functions/variables
-  Compile error triggers if someone tries to use
`Output.enable_ansi_colors`

## Stats

- 24 files changed
- 58 insertions, 77 deletions (net -19 lines)
- 49 usages correctly updated
- 3 items deleted/deprecated

476e1cfe69 Make 'bun list' an alias for 'bun pm ls' (#24159)
## Summary

This PR makes `bun list` an alias for `bun pm ls`, allowing users to
list their dependency tree with a shorter command.

## Changes

- Updated `src/cli.zig` to route `list` command to
`PackageManagerCommand` instead of `ReservedCommand`
- Modified `src/cli/package_manager_command.zig` to detect when `bun
list` is invoked directly and treat it as `ls`
- Updated help text in `bun pm --help` to show both `bun list` and `bun
pm ls` as valid options

## Implementation Details

The implementation follows the same pattern used for `bun whoami`, which
is also a direct alias to a pm subcommand. When `bun list` is detected,
it's internally converted to the `ls` subcommand.

## Testing

Tested locally:
-  `bun list` shows the dependency tree
-  `bun list --all` works correctly with the `--all` flag
-  `bun pm ls` continues to work (backward compatible)

## Test Output

```bash
$ bun list
/tmp/test-bun-list node_modules (3)
└── react@18.3.1

$ bun list --all
/tmp/test-bun-list node_modules
├── js-tokens@4.0.0
├── loose-envify@1.4.0
└── react@18.3.1

$ bun pm ls
/tmp/test-bun-list node_modules (3)
└── react@18.3.1
```

646aede0d4 Fix CPU profiler timestamps - use setDouble() instead of setInteger() (#24206)
## Summary

Fixes CPU profiler generating invalid timestamps that Chrome DevTools
couldn't parse (though VSCode's profiler viewer accepted them).

## The Problem

CPU profiles generated by `--cpu-prof` had timestamps that were either:
1. Negative (in the original broken profile from the gist)
2. Truncated/corrupted (after initial timestamp calculation fix)

Example from the broken profile:
```json
{
  "startTime": -822663297,
  "endTime": -804820609
}
```

After initial fix, timestamps were positive but still wrong:
```json
{
  "startTime": 1573519100,  // Should be ~1761784720948727
  "endTime": 1573849434
}
```

## Root Cause

**Primary Issue**: `WTF::JSON::Object::setInteger()` has precision
issues with large values (> 2^31). When setting timestamps like
`1761784720948727` (microseconds since Unix epoch - 16 digits), the
method was truncating/corrupting them.

**Secondary Issue**: The timestamp calculation logic needed
clarification - now explicitly uses the earliest sample's wall clock
time as startTime and calculates a consistent wallClockOffset.

## The Fix

### src/bun.js/bindings/BunCPUProfiler.cpp

Changed from `setInteger()` to `setDouble()` for timestamp
serialization:

```cpp
// Before (broken):
json->setInteger("startTime"_s, static_cast<long long>(startTime));
json->setInteger("endTime"_s, static_cast<long long>(endTime));

// After (fixed):
json->setDouble("startTime"_s, startTime);
json->setDouble("endTime"_s, endTime);
```

JSON `Number` type can precisely represent integers up to 2^53 (~9
quadrillion), which is far more than needed for microsecond timestamps
(~10^15 for current dates).

Also clarified the timestamp calculation to use `wallClockStart`
directly as the profile's `startTime` and calculate a `wallClockOffset`
for converting stopwatch times to wall clock times.

### test/cli/run/cpu-prof.test.ts

Added validation that timestamps are:
- Positive
- In microseconds (> 1000000000000000, < 3000000000000000)
- Within valid Unix epoch range

## Testing

```bash
bun bd test test/cli/run/cpu-prof.test.ts
```

All tests pass 

Generated profile now has correct timestamps:
```json
{
  "startTime": 1761784720948727.2,
  "endTime": 1761784721305814
}
```

## Why VSCode Worked But Chrome DevTools Didn't

- **VSCode**: Only cares about relative timing (duration = endTime -
startTime), doesn't validate absolute timestamp ranges
- **Chrome DevTools**: Expects timestamps in microseconds since Unix
epoch (positive, ~16 digits), fails validation when timestamps are
negative, too small, or out of valid range

a7fc6eb354 Implement --cpu-prof CLI flag (#24112)
## Summary

Implements the `--cpu-prof` CLI flag for Bun to profile CPU usage and
save results in Chrome CPU Profiler JSON format, compatible with Chrome
DevTools and VSCode.

## Implementation Details

- Uses JSC's `SamplingProfiler` to collect CPU samples during execution
- Converts samples to Chrome CPU Profiler JSON format on exit
- Supports `--cpu-prof-name` to customize output filename
- Supports `--cpu-prof-dir` to specify output directory
- Default filename: `CPU.YYYYMMDD.HHMMSS.PID.0.001.cpuprofile`

## Key Features

 **Chrome DevTools Compatible** - 100% compatible with Node.js CPU
profile format
 **Absolute Timestamps** - Uses wall clock time (microseconds since
epoch)
 **1ms Sampling** - Matches Node.js sampling frequency for comparable
granularity
 **Thread-Safe** - Properly shuts down background sampling thread
before processing
 **Memory-Safe** - Uses HeapIterationScope and DeferGC for safe heap
access
 **Cross-Platform** - Compiles on Windows, macOS, and Linux with proper
path handling

## Technical Challenges Solved

1. **Heap Corruption** - Fixed by calling `profiler->shutdown()` before
processing traces
2. **Memory Safety** - Added `HeapIterationScope` and `DeferGC` when
accessing JSCells
3. **Timestamp Accuracy** - Explicitly start stopwatch and convert to
absolute wall clock time
4. **Path Handling** - Used `bun.path.joinAbsStringBufZ` with proper cwd
resolution
5. **Windows Support** - UTF-16 path conversion for Windows
compatibility
6. **Atomic Writes** - Used `bun.sys.File.writeFile` with ENOENT retry

## Testing

All tests pass (4/4):
-  Generates profile with default name
-  `--cpu-prof-name` sets custom filename
-  `--cpu-prof-dir` sets custom directory
-  Profile captures function names

Verified format compatibility:
- JSON structure matches Node.js exactly
- All samples reference valid nodes
- Timestamps use absolute microseconds since epoch
- Cross-platform compilation verified with `bun run zig:check-all`

## Example Usage

```bash
# Basic usage
bun --cpu-prof script.js

# Custom filename
bun --cpu-prof --cpu-prof-name my-profile.cpuprofile script.js

# Custom directory
bun --cpu-prof --cpu-prof-dir ./profiles script.js
```

Output can be opened in Chrome DevTools (Performance → Load Profile) or
VSCode's CPU profiling viewer.

ddd4018bda Improve snapshot error messages in CI environments (#23419)
## Summary

This PR improves snapshot error messages when running tests in CI
environments to make debugging easier by showing exactly what snapshot
was being created and what value was attempted.

## Changes

### 1. Inline Snapshot Errors
**Before:**
```
Updating inline snapshots is disabled in CI environments unless --update-snapshots is used.
```

**After:**
```
Inline snapshot creation is not allowed in CI environments unless --update-snapshots is used.
If this is not a CI environment, set the environment variable CI=false to force allow.

Received: this is new
```

- Changed message to say "creation" instead of "updating" (more
accurate)
- Shows the received value that was attempted using Jest's pretty
printer

### 2. Snapshot File Errors
**Before:**
```
Snapshot creation is not allowed in CI environments unless --update-snapshots is used
If this is not a CI environment, set the environment variable CI=false to force allow.

Received: this is new
```

**After:**
```
Snapshot creation is not allowed in CI environments unless --update-snapshots is used
If this is not a CI environment, set the environment variable CI=false to force allow.

Snapshot name: "new snapshot 1"
Received: this is new
```

- Now shows the snapshot name that was being looked for
- Shows the received value using Jest's pretty printer

## Implementation Details

- Added `last_error_snapshot_name` field to `Snapshots` struct to pass
snapshot name from `getOrPut()` to error handler
- Removed unreachable code path for inline snapshot updates (mismatches
error earlier with diff)
- Updated test expectations in `ci-restrictions.test.ts`

## Test Plan

```bash
# Test inline snapshot creation in CI
cd /tmp/snapshot-test
echo 'import { test, expect } from "bun:test";
test("new inline snapshot", () => {
  expect("this is new").toMatchInlineSnapshot();
});' > test.js
GITHUB_ACTIONS=1 bun test test.js

# Test snapshot file creation in CI
echo 'import { test, expect } from "bun:test";
test("new snapshot", () => {
  expect("this is new").toMatchSnapshot();
});' > test2.js
GITHUB_ACTIONS=1 bun test test2.js
```

Both should show improved error messages with the received values and
snapshot name.

1de4448425 Fix duplicate issue bot to respect 👎 reactions and not re-close reopened issues (#24203)
## Summary

Fixed two bugs in the auto-close-duplicates bot:

- **Respect 👎 reactions from ANY user**: Previously only the issue
author's thumbs down would prevent auto-closing. Now any user can
indicate disagreement with the duplicate detection.
- **Don't re-close reopened issues**: The bot now checks if an issue was
previously reopened and skips auto-closing to respect user intent.

## Changes

1. Modified `fetchAllReactions` call to check all reactions, not just
the author's
2. Changed `authorThumbsDown` logic to `hasThumbsDown` (checks any
user's reaction)
3. Added `wasIssueReopened()` function to query issue events timeline
4. Added check to skip issues with "reopened" events in their history

## Test plan

- [ ] Manually test the script doesn't close issues with 👎 reactions
from non-authors
- [ ] Verify reopened issues are not auto-closed again
- [ ] Check that legitimate duplicates without objections still get
closed properly

98c04e37ec Fix source index bounds check in sourcemap decoder (#24145)
## Summary

Fix the source index bounds check in `src/sourcemap/Mapping.zig` to
correctly validate indices against the range `[0, sources_count)`.

## Changes

- Changed the bounds check condition from `source_index > sources_count`
to `source_index >= sources_count` on line 452
- This prevents accepting `source_index == sources_count`, which would
be out of bounds when indexing into the sources array

## Test plan

- [x] Built successfully with `bun bd`
- The existing test suite should continue to pass

4f1b90ad1d Fix EventEmitter crash in removeAllListeners with removeListener meta-listener (#24148)
## Summary

Fixes #24147

- Fixed EventEmitter crash when `removeAllListeners()` is called from
within an event handler while a `removeListener` meta-listener is
registered
- Added undefined check before iterating over listeners array to match
Node.js behavior
- Added comprehensive regression tests

## Bug Description

When `removeAllListeners(type)` was called:
1. From within an event handler 
2. While a `removeListener` meta-listener was registered
3. For an event type with no listeners

It would crash with: `TypeError: undefined is not an object (evaluating
'this._events')`

## Root Cause

The `removeAllListeners` function tried to access `listeners.length`
without checking if `listeners` was defined first. When called with an
event type that had no listeners, `events[type]` returned `undefined`,
causing the crash.

## Fix

Added a check `if (listeners !== undefined)` before iterating, matching
the behavior in Node.js core:
https://github.com/nodejs/node/blob/main/lib/events.js#L768

## Test plan

-  Created regression test in `test/regression/issue/24147.test.ts`
-  Verified test fails with `USE_SYSTEM_BUN=1 bun test` (reproduces
bug)
-  Verified test passes with `bun bd test` (confirms fix)
-  Test covers the exact reproduction case from the issue
-  Additional tests for edge cases (actual listeners, nested calls)

51431b6e65 Fix sourcemap comparator to use strict weak ordering (#24146)
## Summary

Fixes the comparator function in `src/sourcemap/Mapping.zig` to use
strict weak ordering as required by sort algorithms.

## Changes

- Changed `<=` to `<` in the column comparison to ensure strict ordering
- Refactored the comparator to use clearer if-statement structure
- Added index comparison as a tiebreaker for stable sorting when both
line and column positions are equal

## Problem

The original comparator used `<=` which would return true for equal
elements, violating the strict weak ordering requirement. This could
lead to undefined behavior in sorting.

**Before:**
```zig
return a.lines.zeroBased() < b.lines.zeroBased() or (a.lines.zeroBased() == b.lines.zeroBased() and a.columns.zeroBased() <= b.columns.zeroBased());
```

**After:**
```zig
if (a.lines.zeroBased() != b.lines.zeroBased()) {
    return a.lines.zeroBased() < b.lines.zeroBased();
}
if (a.columns.zeroBased() != b.columns.zeroBased()) {
    return a.columns.zeroBased() < b.columns.zeroBased();
}
return a_index < b_index;
```

## Test plan

- [x] Verified compilation with `bun bd`
- The sort now properly follows strict weak ordering semantics

eb77bdd286 Refactor: Split sourcemap.zig into separate struct files (#24141)
## Summary

This PR refactors the sourcemap module by extracting large structs from
`src/sourcemap/sourcemap.zig` into their own dedicated files, improving
code organization and maintainability.

## Changes

- **Extracted `ParsedSourceMap` struct** to
`src/sourcemap/ParsedSourceMap.zig`
  - Made `SourceContentPtr` and related methods public
  - Made `standaloneModuleGraphData` public for external access
  
- **Extracted `Chunk` struct** to `src/sourcemap/Chunk.zig`
  - Added import for `appendMappingToBuffer` from parent module
  - Includes all nested types: `VLQSourceMap`, `NewBuilder`, `Builder`
  
- **Extracted `Mapping` struct** to `src/sourcemap/Mapping.zig`
  - Added necessary imports: `assert`, `ParseResult`, `debug`
  - Includes nested types: `MappingWithoutName`, `List`, `Lookup`

- **Updated `src/sourcemap/sourcemap.zig`**
- Replaced struct definitions with imports:
`@import("./StructName.zig")`
  - Maintained all public APIs

All structs now follow the `const StructName = @This()` pattern for
top-level declarations.

## Testing

-  Compiled successfully with `bun bd`
-  All existing functionality preserved
-  No API changes - fully backwards compatible

## Before

- Single 2000+ line file with multiple large structs
- Difficult to navigate and maintain

## After

- Modular structure with separate files for each major struct
- Easier to find and modify specific functionality
- Better code organization

668eba0eb8 fix(node:http): Fix ServerResponse.writableNeedDrain causing stream pause (#24137)
## Summary

Fixes #19111

This PR fixes a bug where `fs.createReadStream().pipe(ServerResponse)`
would fail to transfer data when ServerResponse had no handle
(standalone usage). This affected Vite's static file serving and other
middleware adapters using the connect-to-web pattern.

## Root Cause

The bug was in the `ServerResponse.writableNeedDrain` getter at line
1529 of `_http_server.ts`:

```typescript
return !this.destroyed && !this.finished && (this[kHandle]?.bufferedAmount ?? 1) !== 0;
```

When `ServerResponse` had no handle (which is common in middleware
scenarios), the nullish coalescing operator defaulted `bufferedAmount`
to **1** instead of **0**. This caused `writableNeedDrain` to always
return `true`.

## Impact

When `pipe()` checks `dest.writableNeedDrain === true`, it immediately
pauses the source stream to handle backpressure. With the bug,
standalone ServerResponse instances always appeared to need draining,
causing piped streams to pause and never resume.

## Fix

Changed the default value from `1` to `0`:

```typescript
return !this.destroyed && !this.finished && (this[kHandle]?.bufferedAmount ?? 0) !== 0;
```

## Test Plan

-  Added regression test in `test/regression/issue/19111.test.ts`
-  Verified fix with actual Vite middleware reproduction
-  Confirmed behavior matches Node.js

6580b563b0 Refactor Subprocess to use JSRef instead of hasPendingActivity (#24090)
## Summary

Refactors `Subprocess` to use explicit strong/weak reference management
via `JSRef` instead of the `hasPendingActivity` mechanism that relies on
JSC's internal `WeakHandleOwner`.

## Changes

### Core Refactoring
- **JSRef.zig**: Added `update()` method to update references in-place
- **subprocess.zig**: Changed `this_jsvalue: JSValue` to `this_value:
JSRef`
- **subprocess.zig**: Renamed `hasPendingActivityNonThreadsafe()` to
`computeHasPendingActivity()`
- **subprocess.zig**: Updated `updateHasPendingActivity()` to
upgrade/downgrade `JSRef` based on pending activity
- **subprocess.zig**: Removed `hasPendingActivity()` C callback function
- **subprocess.zig**: Updated `finalize()` to call
`this_value.finalize()`
- **BunObject.classes.ts**: Set `hasPendingActivity: false` for
Subprocess
- **Writable.zig**: Updated references from `this_jsvalue` to
`this_value.tryGet()`
- **ipc.zig**: Updated references from `this_jsvalue` to
`this_value.tryGet()`

## How It Works

**Before**: Used `hasPendingActivity: true` which created a `JSC::Weak`
reference with a `JSC::WeakHandleOwner` that kept the object alive as
long as the C callback returned true.

**After**: Uses `JSRef` with explicit lifecycle management:
1. Starts with a **weak** reference when subprocess is created
2. Immediately calls `updateHasPendingActivity()` after creation
3. **Upgrades to strong** reference when `computeHasPendingActivity()`
returns true:
   - Subprocess hasn't exited
   - Has active stdio streams
   - Has active IPC connection
4. **Downgrades to weak** reference when all activity completes
5. GC can collect the subprocess once it's weak and no other references
exist

## Benefits

- Explicit control over subprocess lifecycle instead of relying on JSC's
internal mechanisms
- Clearer semantics: strong reference = "keep alive", weak reference =
"can be GC'd"
- Removes dependency on `WeakHandleOwner` callback overhead

## Testing

-  `test/js/bun/spawn/spawn.ipc.test.ts` - All 4 tests pass
-  `test/js/bun/spawn/spawn-stress.test.ts` - All tests pass (100
iterations)
- ⚠️ `test/js/bun/spawn/spawnSync.test.ts` - 3/6 pass (3 pre-existing
timing-based failures unrelated to this change)

Manual testing confirms:
- Subprocess is kept alive without user reference while running
- Subprocess can be GC'd after completion
- IPC keeps subprocess alive correctly
- No crashes or memory leaks

f3ed784a6b scripts: teach machine.mjs how to spawn a freebsd image on aws (#24109)
exploratory look into https://github.com/oven-sh/bun/issues/1524
this still leaves that far off from being closed but an important first
step
this is important because this script is used to spawn our base images
for CI and will provide boxes for local testing

not sure how far i'll get but a rough "road to freebsd" map for anyone
reading:

- [x] this
- [ ] ensure `bootstrap.sh` can run successfully
- [ ] ensure WebKit can build from source
- [ ] ensure other dependencies can build from source
- [ ] add freebsd to our WebKit fork releases
- [ ] add freebsd to our Zig fork releases
- [ ] ensure bun can build from source
- [ ] run `[build images]` and add freebsd to CI
- [ ] fix runtime test failures

a75cef5079 Add comprehensive documentation for JSRef (#24095)
## Summary

- Adds detailed documentation explaining JSRef's intended usage
- Includes a complete example showing common patterns
- Explains the three states (weak, strong, finalized) 
- Provides guidelines on when to use strong vs weak references
- References real examples from the codebase (ServerWebSocket,
UDPSocket, MySQLConnection, ValkeyClient)

## Motivation

JSRef is a critical type for managing JavaScript object references from
native code, but it lacked comprehensive documentation explaining its
usage patterns and lifecycle management. This makes it clearer how to
properly use JSRef to:

- Safely maintain references to JS objects from native code
- Control whether references prevent garbage collection
- Manage the upgrade/downgrade pattern based on object activity

## Test plan

Documentation-only change, no functional changes.

3367fa6ae3 Refactor: Extract ModuleLoader components into separate files (#24083)
## Summary

Split `ModuleLoader.zig` into smaller, more focused modules for better
code organization and maintainability:

- `AsyncModule` → `src/bun.js/AsyncModule.zig` (lines 69-806)
- `RuntimeTranspilerStore` → `src/bun.js/RuntimeTranspilerStore.zig`
(lines 2028-2606)
- `HardcodedModule` → `src/bun.js/HardcodedModule.zig` (lines 2618-3040)

## Changes

- Extracted three large components from `ModuleLoader.zig` into separate
files
- Updated imports in all affected files
- Made necessary functions/constants public (`dumpSource`,
`dumpSourceString`, `setBreakPointOnFirstLine`, `bun_aliases`)
- Updated `ModuleLoader.zig` to import the new modules

## Testing

- Build passes successfully (`bun bd`)
- Basic module loading verified with smoke tests
- Existing resolve tests continue to pass

f4b6396eac Fix unhandled exception in JSC__JSPromise__wrap when resolving promise (#23961)
### What does this PR do?

Previously, `JSC__JSPromise__wrap` would call
`JSC::JSPromise::resolvedPromise(globalObject, result)` without checking
if an exception was thrown during promise resolution. This
could happen in certain edge cases, such as when the result value is a
thenable that triggers stack overflow, or when the promise resolution
mechanism itself encounters an error.
When such exceptions occurred, they would escape back to the Zig code,
causing the CatchScope assertion to fail with "ASSERTION FAILED:
Unexpected exception observed on thread"
instead of being properly handled.

This PR adds an exception check immediately after calling
`JSC::JSPromise::resolvedPromise()` and before the `RELEASE_AND_RETURN`
macro. If an exception is detected, the function
now clears it and returns a rejected promise with the exception value,
ensuring consistent error handling behavior. This matches the pattern
already used earlier in the function
for the initial function call exception handling.

cfe561a083 fix: allow lifecycle hooks to accept options as second parameter (#24039)
## Summary

Fixes #23133

This PR fixes a bug where lifecycle hooks (`beforeAll`, `beforeEach`,
`afterAll`, `afterEach`) would throw an error when called with a
function and options object:

```typescript
beforeAll(() => {
  console.log("beforeAll")
}, { timeout: 10_000 })
```

Previously, this would throw: `error: beforeAll() expects a function as
the second argument`

## Root Cause

The issue was in `ScopeFunctions.parseArguments()` at
`src/bun.js/test/ScopeFunctions.zig:342`. When parsing two arguments, it
always treated them as `(description, callback)` instead of checking if
they could be `(callback, options)`.

## Solution

Updated the two-argument parsing logic to check if the first argument is
a function and the second is not a function. In that case, treat them as
`(callback, options)` instead of `(description, callback)`.

## Changes

- Modified `src/bun.js/test/ScopeFunctions.zig` to handle `(callback,
options)` case
- Added regression test at `test/regression/issue/23133.test.ts`

## Testing

 Verified the fix works with the reproduction case from the issue
 Added comprehensive regression test covering all lifecycle hooks with
both object and numeric timeout options
 All existing jest-hooks tests still pass
 Test fails with `USE_SYSTEM_BUN=1` and passes with the fixed build

5a7b824091 fix(css): process color-scheme rules inside @layer blocks (#24034)
## Summary

Fixes #20689

Previously, `@layer` blocks were not being processed through the CSS
minifier, which meant that `color-scheme` properties inside `@layer`
blocks would not get the required `--buncss-light`/`--buncss-dark`
variable injections needed for browsers that don't support the
`light-dark()` function.

## Changes

- Implemented proper minification for `LayerBlockRule` in
`src/css/rules/rules.zig:218-221`
- Added recursive call to `minify()` on nested rules, matching the
behavior of other at-rules like `@media` and `@supports`
- Added comprehensive tests for `color-scheme` inside `@layer` blocks

## Test Plan

Added three new test cases in `test/js/bun/css/css.test.ts`:
1. Simple `@layer` with `color-scheme: dark`
2. Named layers (`@layer shm.colors`) with multiple rules
3. Anonymous `@layer` with `color-scheme: light dark` (generates media
query)

All tests pass:
```bash
bun bd test test/js/bun/css/css.test.ts -t "color-scheme"
```

## Before

```css
/* Input */
@layer shm.colors {
  body.theme-dark {
    color-scheme: dark;
  }
}

/* Output (broken - no variables) */
@layer shm.colors {
  body.theme-dark {
    color-scheme: dark;
  }
}
```

## After

```css
/* Input */
@layer shm.colors {
  body.theme-dark {
    color-scheme: dark;
  }
}

/* Output (fixed - variables injected) */
@layer shm.colors {
  body.theme-dark {
    --buncss-light: ;
    --buncss-dark: initial;
    color-scheme: dark;
  }
}
```

a3f18b9e0e feat(test): implement onTestFinished hook for bun:test (#24038)
## Summary

Implements `onTestFinished()` for `bun:test`, which runs after all
`afterEach` hooks have completed.

## Implementation

- Added `onTestFinished` export to the test module in `jest.zig`
- Modified `genericHook` in `bun_test.zig` to handle `onTestFinished` as
a special case that:
  - Can only be called inside a test (not in describe blocks or preload)
  - Appends hooks at the very end of the execution sequence
- Added comprehensive tests covering basic ordering, multiple callbacks,
async callbacks, and interaction with other hooks

## Execution Order

When called inside a test:
1. Test body executes
2. `afterAll` hooks (if added inside the test)
3. `afterEach` hooks
4. `onTestFinished` hooks 

## Test Plan

-  All new tests pass with `bun bd test`
-  Tests correctly fail with `USE_SYSTEM_BUN=1` (feature not in
released version)
-  Verifies correct ordering with `afterEach`, `afterAll`, and multiple
`onTestFinished` calls
-  Tests async `onTestFinished` callbacks

afd125fc12 docs(env_var): document silent error handling behavior (#24043)
### What does this PR do?

This PR adds documentation comments to `src/env_var.zig` that explain
the silent error handling behavior for environment variable
deserialization, based on the documentation from the closed PR #24036.

The comments clarify:

1. **Module-level documentation**: Environment variables may fail to
parse silently. When they do, the default behavior is to show a debug
warning and treat them as not set. This is intentional to avoid panics
from environment variable pollution.

2. **Inline documentation**: Deserialization errors cannot panic. Users
needing more robust configuration mechanisms should consider
alternatives to environment variables.

This documentation complements the behavior change introduced in commit
0dd6aa47ea which replaced panic with debug_warn.

### How did you verify your code works?

Ran `bun bd` successfully - the build completed without errors.

29028bbabe docs(watch): rename filename to relativePath in recursive example (#23990)
When using `fs.watch()` with `recursive: true`, the callback receives a
relative path from the watched directory (e.g., `'subdir/file.txt'`),
not just a filename.

Renaming the parameter from `filename` to `relativePath` makes this
behavior immediately clear to developers.

**Before:**
```ts
(event, filename) => {
  console.log(`Detected ${event} in ${filename}`);
}
```

**After:**
```ts
(event, relativePath) => {
  console.log(`Detected ${event} in ${relativePath}`);
}
```

This is a documentation-only change that improves clarity without
altering any functionality.

5a82e85876 Fix integer overflow when reading MySQL OK packets (#23993)
### Description
This PR fixes a crash caused by integer underflow in
`OKPacket.decodeInternal`.
Previously, when `read_size` exceeded `packet_size`, the subtraction  
`packet_size - read_size` wrapped around, producing a huge `count` value
passed into `reader.read()`. This led to an integer overflow panic at
runtime.

### What does this PR do
- Added a safe subtraction guard in `decodeInternal` to clamp
`remaining` to `0`
  when `read_size >= packet_size`.  
- Ensures empty or truncated OK packets no longer cause crashes.  
- Behavior for valid packets remains unchanged.

### Impact
Prevents integer overflow panics in MySQL OK packet parsing, improving  
stability when handling short or empty responses (e.g., queries that  
return no rows or minimal metadata).

24d9d642de ProxyTunnel: close-delimited responses via proxy cause ECONNRESET (#23719)
fixes: oven-sh/bun#23717

### What does this PR do?
- Align ProxyTunnel.onClose with
[HTTPClient.onClose](https://github.com/oven-sh/bun/blob/bun-v1.3.0/src/http.zig#L223-L241):
when a tunneled HTTPS response is in-progress and either
  - parsing chunked trailers (trailer-line states), or
- transfer-encoding is identity with content_length == null while in
.body,
treat EOF as end-of-message and complete the request, rather than
ECONNRESET.
- Schedule proxy deref instead of deref inside callbacks to avoid
lifetime hazards.

### How did you verify your code works?
- `test/js/bun/http/proxy.test.ts`: raw TLS origin returns
close-delimited 200 OK; verified no ECONNRESET and body delivered.
- Test suite passes under bun bd test.

## Risk/compat
- Only affects CONNECT/TLS path. Direct HTTP/HTTPS unchanged. Behavior
mirrors existing
[HTTPClient.onClose](https://github.com/oven-sh/bun/blob/bun-v1.3.0/src/http.zig#L223-L241).

## Repro (minimal)
See issue; core condition is no Content-Length and no Transfer-Encoding
(close-delimited).

b278c85753 Refactor NapiEnv to use ExternalShared for safer reference counting (#23982)
## Summary

This PR refactors `NapiEnv` to use `bun.ptr.ExternalShared` instead of
manual `ref()`/`deref()` calls, fixing a use-after-free bug in the NAPI
implementation.

## Bug Fixed

The original issue was in `ThreadSafeFunction.deinit()`:
1. `maybeQueueFinalizer()` schedules a task that holds a pointer to
`this` (which includes `this.env`)
2. The task will eventually call `onDispatch()` → `deinit()`
3. But `deinit()` immediately calls `this.env.deref()` before the task
completes
4. This could cause the `NapiEnv` reference count to go to 0 while the
pointer is still in use

## Changes

### Core Changes
- Added `NapiEnv.external_shared_descriptor` and `NapiEnv.EnvRef` type
alias
- Changed struct fields from `*NapiEnv` to `NapiEnv.EnvRef` where
ownership is required:
  - `ThreadSafeFunction.env`
  - `napi_async_work.env`
  - `Finalizer.env` (now `NapiEnv.EnvRef.Optional`)

### API Changes
- Use `.get()` to access the raw `*NapiEnv` pointer from `EnvRef`
- Use `.cloneFromRaw(env)` when storing `env` in long-lived structs
- Use `EnvRef.deinit()` instead of manual `env.deref()`
- Removed manual `env.ref()` calls (now handled automatically by
`cloneFromRaw`)

### Safety Improvements
- Reference counting is now managed by the `ExternalShared` wrapper
- Prevents manual ref/deref mistakes
- Ensures proper cleanup even when operations are cancelled or fail
- No more use-after-free risks from premature deref

## Testing

Built successfully with `bun bd`. NAPI tests pass (66/83 tests, with 17
timeouts that appear to be pre-existing issues).

## Implementation Notes

Following the pattern from `Blob.zig` and `array_buffer.zig`, structs
that own a reference use `NapiEnv.EnvRef`, while functions that only
borrow temporarily continue to use `*NapiEnv` parameters.

The `ExternalShared` interface ensures:
- `.clone()` increments the ref count
- `.deinit()` decrements the ref count
- No direct access to the internal ref/deref functions

This makes the ownership semantics explicit and type-safe.

0ad4e6af2d Fix Buffer.isEncoding('') to return false (#23968)
## Summary
Fixes `Buffer.isEncoding('')` to return `false` instead of `true`,
matching Node.js behavior.

## Description
Previously, `Buffer.isEncoding('')` incorrectly returned `true` in Bun,
while Node.js correctly returns `false`. This was caused by
`parseEnumerationFromView` in `JSBufferEncodingType.cpp` treating empty
strings (length 0) as valid utf8 encoding.

The fix modifies the switch statement to return `std::nullopt` for empty
strings, along with other invalid short strings.

## Changes
- Modified `src/bun.js/bindings/JSBufferEncodingType.cpp` to return
`std::nullopt` for empty strings
- Added regression test `test/regression/issue23966.test.ts`

## Test Plan
- [x] Test fails with `USE_SYSTEM_BUN=1 bun test
test/regression/issue23966.test.ts` (confirms bug exists)
- [x] Test passes with `bun bd test test/regression/issue23966.test.ts`
(confirms fix works)
- [x] Verified behavior matches Node.js v24.3.0
- [x] All test cases for valid/invalid encodings pass

Fixes #23966

a3c43dc8b9 Fix Windows bunx fast path index out of bounds panic (#23938)
## Summary

Fixed a bug in the Windows bunx fast path code where UTF-8 byte length
was incorrectly used instead of UTF-16 code unit length when calculating
buffer offsets.

## Details

In `run_command.zig:1565`, the code was using `target_name.len` (UTF-8
byte length) instead of `encoded.len` (UTF-16 code unit length) when
calculating the total path length. This caused an index out of bounds
panic when package names contained multi-byte UTF-8 characters.

**Example scenario:**
- Package name contains character "中" (U+4E2D)
- UTF-8: 3 bytes (0xE4 0xB8 0xAD) → `target_name.len` counts as 3
- UTF-16: 1 code unit (0x4E2D) → `encoded.len` counts as 1
- Using the wrong length led to: `panic: index out of bounds: index 62,
len 60`

## Changes

- Changed line 1565 from `target_name.len` to `encoded.len`

## Test plan

- [x] Build compiles successfully
- [x] Code review confirms the fix addresses the root cause
- [ ] Windows-specific testing (if available)

Fixes the panic reported in Sentry/crash reports.

d846e9a1e7 Fix bun.String.toOwnedSliceReturningAllASCII (#23925)
`bun.String.toOwnedSliceReturningAllASCII` is supposed to return a
boolean indicating whether or not the string is entirely composed of
ASCII characters. However, the current implementation frequently
produces incorrect results:

* If the string is a `ZigString`, it always returns true, even though
`ZigString`s can be UTF-16 or Latin-1.
* If the string is a `StaticZigString`, it always returns false, even
though `StaticZigStrings` can be all ASCII.
* If the string is a 16-bit `WTFStringImpl`, it always returns false,
even though 16-bit `WTFString`s can be all ASCII.
* If the string is empty, it always returns false, even though empty
strings are valid ASCII strings.

`toOwnedSliceReturningAllASCII` is currently used in two places, both of
which assume its answer is accurate:

* `bun.webcore.Blob.fromJSWithoutDeferGC`
* `bun.api.ServerConfig.fromJS`

3bc78598c6 bug(SlicedString.zig): Fix incorrect assertion in SlicedString.sub (#23934)
### What does this PR do?

Fixes a small bug I found in https://github.com/oven-sh/bun/pull/23107
which caused `SlicedString` not to correctly provide us with subslices.

This would have been a **killer** use-case for the interval utility we
decided to reject in https://github.com/oven-sh/bun/pull/23882. Consider
how nice the code could've been:

```zig
pub inline fn sub(this: SlicedString, input: string) SlicedString {
    const buf_r = bun.math.interval.fromSlice(this.buf);
    const inp_r = bun.math.interval.fromSlice(this.input);

    if (Environment.allow_assert) {
        if (!buf_r.superset(inp_r)) {
            bun.Output.panic("SlicedString.sub input [{}, {}) is not a substring of the " ++
                "slice [{}, {})", .{ start_i, end_i, start_buf, end_buf });
        }
    }
    return SlicedString{ .buf = this.buf, .slice = input };
}
```

That's a lot more readable than the middle-school algebra we have here,
but here we are.

88fa296dcd Add GitHub issue deduplication automation (#23926)
## Summary

This PR adds a Claude Code-powered issue deduplication system to help
reduce duplicate issues in the Bun repository.

### What's included:

1. **`/dedupe` slash command** (`.claude/commands/dedupe.md`)
- Claude Code command to find up to 3 duplicate issues for a given
GitHub issue
   - Uses parallel agent searches with diverse keywords
   - Filters out false positives

2. **Automatic dedupe on new issues**
(`.github/workflows/claude-dedupe-issues.yml`)
   - Runs automatically when a new issue is opened
   - Can also be triggered manually via workflow_dispatch
   - Uses the Claude Code base action to run the `/dedupe` command

3. **Auto-close workflow**
(`.github/workflows/auto-close-duplicates.yml`)
   - Runs daily to close issues marked as duplicates after 3 days
   - Only closes if:
     - Issue has a duplicate detection comment from bot
     - Comment is 3+ days old
     - No comments or activity after duplicate comment
     - Author hasn't reacted with 👎 to the duplicate comment

4. **Auto-close script** (`scripts/auto-close-duplicates.ts`)
   - TypeScript script that handles the auto-closing logic
   - Fetches open issues and checks for duplicate markers
   - Closes issues with proper labels and notifications

### How it works:

1. When a new issue is opened, the workflow runs Claude Code to analyze
it
2. Claude searches for duplicates and comments on the issue if any are
found
3. Users have 3 days to respond if they disagree
4. After 3 days with no activity, the issue is automatically closed

### Requirements:

- `ANTHROPIC_API_KEY` secret needs to be set in the repository settings
for the dedupe workflow to run

## Test plan

- [x] Verified workflow files have correct syntax
- [x] Verified script references correct repository (oven-sh/bun)
- [x] Verified slash command matches claude-code implementation
- [ ] Test workflow manually with workflow_dispatch (requires
ANTHROPIC_API_KEY)
- [ ] Monitor initial runs to ensure proper behavior

cd8043b76e Fix Bun.build() compile API to properly apply sourcemaps (#23916)
## Summary

Fixes a bug where the `Bun.build()` API with `compile: true` did not
properly apply sourcemaps, even when `sourcemap: "inline"` was
specified. This resulted in error stack traces showing bundled virtual
paths (`/$bunfs/root/`) instead of actual source file names and line
numbers.

## Problem

The CLI `bun build --compile --sourcemap` worked correctly, but the
equivalent API call did not:

```javascript
// This did NOT work (before fix)
await Bun.build({
  entrypoints: ['./app.js'],
  compile: true,
  sourcemap: "inline"  // <-- Was ignored/broken
});
```

Error output showed bundled paths:
```
error: Error from helper module
      at helperFunction (/$bunfs/root/app.js:4:9)  //  Wrong path
      at main (/$bunfs/root/app.js:9:17)            //  Wrong line numbers
```

## Root Cause

The CLI explicitly overrides any sourcemap type to `.external` when
compile mode is enabled (in `/workspace/bun/src/cli/Arguments.zig`):

```zig
// when using --compile, only `external` works
if (ctx.bundler_options.compile) {
    opts.source_map = .external;
}
```

The API implementation in `JSBundler.zig` was missing this override.

## Solution

Added the same sourcemap override logic to `JSBundler.zig` when compile
mode is enabled:

```zig
// When using --compile, only `external` sourcemaps work, as we do not
// look at the source map comment. Override any other sourcemap type.
if (this.source_map != .none) {
    this.source_map = .external;
}
```

Now error output correctly shows source file names:
```
error: Error from helper module
      at helperFunction (helper.js:2:9)  //  Correct file
      at main (app.js:4:3)                //  Correct line numbers
```

## Tests

Added comprehensive test coverage in
`/workspace/bun/test/bundler/bun-build-compile-sourcemap.test.ts`:

-  `sourcemap: "inline"` works
-  `sourcemap: true` works
-  `sourcemap: "external"` works
-  Multiple source files show correct file names
-  Without sourcemap, bundled paths are shown (expected behavior)

All tests:
-  Fail with `USE_SYSTEM_BUN=1` (confirms bug exists)
-  Pass with `bun bd test` (confirms fix works)
-  Use `tempDir()` to avoid disk space issues

150338faab implement publicHoistPattern and hoistPattern (#23567)
### What does this PR do?
Adds support for `publicHoistPattern` in `bunfig.toml` and
`public-hoist-pattern` from `.npmrc`. This setting allows you to select
transitive packages to hoist to the root node_modules making them
available for all workspace packages.

```toml
[install]
# can be a string
publicHoistPattern = "@types*"
# or an array
publicHoistPattern = [ "@types*", "*eslint*" ]
```

`publicHoistPattern` only affects the isolated linker.

---

Adds `hoistPattern`. `hoistPattern` is the same as `publicHoistPattern`,
but applies to the `node_modules/.bun/node_modules` directory instead of
the root node_modules. Also the default value of `hoistPattern` is `*`
(everything is hoisted to `node_modules/.bun/node_modules` by default).

---

Fixes a determinism issue constructing the
`node_modules/.bun/node_modules` directory.

3e53ada574 Fix assertion failure when using --production flag (#23821)
Fixes #19652

## Summary

Fixes a crash that occurred when using the `--production` flag with `bun
build`, particularly on Windows where assertions are enabled in release
builds.

## Root Cause

The crash occurred because an assertion for `jsx.development` was
running **before** `jsx.development` was properly configured. The
problematic sequence was:

1. Set `NODE_ENV=production` in env map
2. Call `configureDefines()` which reads `NODE_ENV` and calls
`setProduction(true)`, setting `jsx.development=false`
3.  **Assert `jsx.development` is false** (assertion fired here, before
line 203 below)
4. Set `jsx.development = !production` on line 203 (too late)

## Changes

This PR reorders the code to move the assertion **after**
`jsx.development` is properly set:

1. Set both `BUN_ENV` and `NODE_ENV` to `"production"` in env map
2. Call `configureDefines()` 
3. Set `jsx.development = !production` (now happens first)
4.  **Assert `jsx.development` is false** (now runs after it's set)

Also adds `BUN_ENV=production` to match the behavior of setting
`NODE_ENV`.

## Test Plan

Added regression test in `test/regression/issue/19652.test.ts` that
verifies `bun build --production` doesn't crash.

The test:
-  Passes on this branch
-  Would fail on main (assertion failure)

5971bf67ef fix: buffer allocation for path operations with very long paths (#23819)
## Summary

Fixed an off-by-one error in buffer allocation for several path module
functions when handling paths longer than `PATH_SIZE` (typically 4096
bytes on most platforms).

## Changes

- `normalizeJS_T`: Added +1 to buffer allocation for null terminator
- `relativeJS_T`: Added +1 to buffer allocation for null terminator  
- `toNamespacedPathJS_T`: Added +9 bytes (8 for possible UNC prefix + 1
for null terminator)

## Test plan

- Added tests for `path.normalize()` with paths up to 100,000 characters
- Added tests for `path.relative()` with very long paths
- All existing path tests continue to pass

The issue occurred because when a path is exactly equal to or longer
than `PATH_SIZE`, the buffer was allocated with size equal to the path
length, but then a null terminator was written at `buf[bufSize]`, which
was out of bounds.

686998ed3d Fix panic when WebSocket close frame is fragmented across TCP packets (#23832)
## Summary

Fixes a panic that occurred when a WebSocket close frame's payload was
split across multiple TCP packets.

## The Bug

The panic occurred at `websocket_client.zig:681`:
```
panic: index out of bounds: index 24, len 14
```

This happened when:
- A close frame had a payload of 24 bytes (2 byte code + 22 byte reason)
- The first TCP packet contained 14 bytes (header + partial payload)
- The code tried to access `data[2..24]` causing the panic

## Root Causes

1. **Bounds checking issue**: The code assumed all close frame data
would arrive in one packet and tried to `@memcpy` without verifying
sufficient data was available.

2. **Premature flag setting**: `close_received = true` was set
immediately upon entering the close state. This prevented `handleData`
from being called again when the remaining bytes arrived (early return
at line 354).

## The Fix

Implemented proper fragmentation handling for close frames, following
the same pattern used for ping frames:

- Added `close_frame_buffering` flag to track buffering state
- Buffer incoming data incrementally using the existing
`ping_frame_bytes` buffer
- Track total expected length and bytes received so far
- Only set `close_received = true` after all bytes are received
- Wait for more data if the frame is incomplete

## Testing

- Created two regression tests that fragment close frames across
multiple packets
- All existing WebSocket tests pass (`test/js/web/websocket/`)
- Verified the original panic no longer occurs

## Related

This appears to be the root cause of crashes reported on Windows when
WebSocket connections close, particularly when close frames have reasons
that get fragmented by the network stack.

2557b1cc2a Add email field support to .npmrc for registry authentication (#23709)
### What does this PR do?

This PR implements support for the `email` field in `.npmrc` files for
registry scope authentication. Some private registries (particularly
Nexus) require the email field to be specified in the registry
configuration alongside username/password or token authentication.

The email field can now be specified in `.npmrc` files like:
```ini
//registry.example.com/:email=user@example.com
//registry.example.com/:username=myuser
//registry.example.com/:_password=base64encodedpassword
```

### How did you verify your code works?

1. **Built Bun successfully** - Confirmed the code compiles without
errors using `bun bd --debug`

2. **Wrote comprehensive unit tests** - Added two test cases to
`test/cli/install/npmrc.test.ts`:
   - Test for standalone email field parsing
   - Test for email combined with username/password authentication

3. **Verified tests pass** - Ran `bun bd test
test/cli/install/npmrc.test.ts -t "email"` and confirmed both tests
pass:
   ```
   ✓ 2 pass
   ✓ 0 fail
   ✓ 6 expect() calls
   ```

4. **Code changes include**:
   - Added `email` field to `NpmRegistry` struct in `src/api/schema.zig`
   - Updated `encode()` and `decode()` methods to handle the email field
   - Modified `ini.zig` to parse and store the email field from `.npmrc`
- Removed email from the unsupported options warning (certfile and
keyfile remain unsupported)
- Updated all `NpmRegistry` struct initializations to include the email
field
   - Updated `loadNpmrcFromJS` test API to return the email field

ebc0cfeacd fix(yaml): double-quoted strings with '...' incorrectly trigger document end error (#23491)
### What does this PR do?

Fixes #23489

The YAML parser was incorrectly treating `...` inside double-quoted
strings as document end markers, causing parse errors for strings
containing ellipsis, particularly affecting internationalized text.

### Example of the bug:
```yaml
balance: "👛 لا تمتلك محفظة... !"
```

This would fail with: `error: Unexpected document end`

### Root cause:

The bug was introduced in commit fcbd57ac48 which attempted to optimize
document marker detection by using `self.line_indent == .none` instead
of tracking newlines with a local flag. However, this check was
incomplete - it didn't track whether we had just processed a newline
character.

### The fix:

Restored the `nl` (newline) flag pattern from the single-quoted scanner
and combined it with the `line_indent` check. Document markers `...` and
`---` are now only recognized when **all** of these conditions are met:

1. We're after a newline (`nl == true`)
2. We're at column 0 (`self.line_indent == .none`)
3. Followed by whitespace or EOF

This allows `...` to appear freely in double-quoted strings while still
correctly recognizing actual document end markers at the start of lines.

### How did you verify your code works?

1. Reproduced the original issue from #23489
2. Applied the fix and verified all test cases pass:
   - Original Arabic text with emoji: `"👛 لا تمتلك محفظة... !"`
   - Various `...` positions: start, middle, end
   - Both single and double quotes
   - Multiline strings with indented `...` (issue #22392)
3. Created regression test in `test/regression/issue/23489.test.ts`
4. Verified existing YAML tests still pass (514 pass, up from 513)

1c4d8b1c1c fix(sql): throw proper exception for invalid MySQL parameter types (#23839)
## Summary

Fixes a panic that occurred when passing `NumberObject` or
`BooleanObject` as MySQL query parameters.

**Panic message:** `A JavaScript exception was thrown, but it was
cleared before it could be read.`

## Root Cause

The `FieldType.fromJS` function in `src/sql/mysql/MySQLTypes.zig` was
returning `error.JSError` without throwing a JavaScript exception first
for:
- `NumberObject` (created via `new Number(42)`)
- `BooleanObject` (created via `new Boolean(true)`)
- Non-indexable types

This violated the contract that `error.JSError` means "an exception has
already been thrown and is ready to be taken."

## Call Chain

1. User executes `await sql\`SELECT ${new Number(42)} as value\``
2. `FieldType.fromJS()` detects `.NumberObject` and returns
`error.JSError` without throwing
3. Error propagates to `MySQLQuery.runPreparedQuery()`
4. Code checks `hasException()` → returns false (no exception exists!)
5. Calls `mysqlErrorToJS(globalObject, "...", error.JSError)`
6. `mysqlErrorToJS` tries to `takeException(error.JSError)` but there's
no exception
7. **PANIC**

## Fix

The fix throws a proper exception with a helpful message before
returning `error.JSError`:
- `"Cannot bind NumberObject to query parameter. Use a primitive number
instead."`
- `"Cannot bind BooleanObject to query parameter. Use a primitive
boolean instead."`
- `"Cannot bind this type to query parameter"`

## Test Plan

Added regression tests in `test/js/sql/sql-mysql.test.ts`:
- Test passing `NumberObject` as parameter
- Test passing `BooleanObject` as parameter

Both tests verify that a proper error is thrown instead of crashing.

Verified manually with local MySQL server that:
-  NumberObject now throws proper error (was crashing)
-  BooleanObject now throws proper error (was crashing)
-  Primitive numbers still work correctly

3921f76ff8 Add --only-failures flag to bun:test (#23312)
## Summary

Adds a new `--only-failures` flag to `bun test` that only displays test
failures, similar to `--dots` but without printing dots for each test.

## Motivation

When running large test suites or in CI environments, users often only
care about test failures. The existing `--dots` reporter reduces
verbosity by showing dots, but still requires visual scanning to find
failures. The `--only-failures` flag provides a cleaner output by
completely suppressing passing tests.

## Changes

- Added `--only-failures` CLI flag in `Arguments.zig`
- Added `only_failures` boolean to the test reporters struct in
`cli.zig`
- Updated test output logic in `test_command.zig` to skip non-failures
when flag is set
- Updated `jest.zig` and `bun_test.zig` to handle the new flag
- Added comprehensive tests in `only-failures.test.ts`

## Usage

```bash
bun test --only-failures
```

Example output (only shows failures):
```
test/example.test.ts:
(fail) failing test
error: expect(received).toBe(expected)

Expected: 3
Received: 2

5 pass
1 skip
2 fail
Ran 8 tests across 1 file.
```

## Test Plan

- Verified `--only-failures` flag only shows failing tests
- Verified normal test output still works without the flag
- Verified `--dots` reporter still works correctly
- Added regression tests with snapshot comparisons

74fa49963c Fix: Error when using bun build --no-bundle with HTML entrypoint (#23572)
Fixes #23569

## Summary

HTML imports require bundling to work correctly, as they need to process
and transform linked assets (JS/CSS). When `--no-bundle` is used, no
bundling or transformation happens, which causes a crash.

This change adds validation to detect HTML entrypoints when
`--no-bundle` is used and provides a clear error message explaining that
"HTML imports are only supported when bundling".

## Changes

- Added validation in `src/cli/build_command.zig` to check for HTML
entrypoints when `--no-bundle` flag is used
- Shows clear error message: "HTML imports are only supported when
bundling"
- Added regression tests in `test/regression/issue/23569.test.ts`

## Test Plan

### Before
```bash
$ bun build ./index.html --no-bundle
# Crashes without helpful error
```

### After
```bash
$ bun build ./index.html --no-bundle
error: HTML imports are only supported when bundling
```

### Tests
-  Test with `--no-bundle` flag errors correctly
-  Test with `--no-bundle --outdir` errors correctly  
-  Test without `--no-bundle` works normally
-  All 3 regression tests pass

767c61d355 Fix memory leaks & blocking syscall in Bun Shell (#23636)
## Summary

Fixes two critical bugs in Bun Shell:

1. **Memory leaks & incorrect GC reporting**: Shell objects weren't
reporting their memory usage to JavaScriptCore's garbage collector,
causing memory to accumulate unchecked. Also fixes a leak where
`ShellArgs` wasn't being freed in `Interpreter.finalize()`.

2. **Blocking I/O on macOS**: Fixes a bug where writing large amounts of
data (>1MB) to pipes would block the main thread on macOS. The issue:
`sendto()` with `MSG_NOWAIT` flag blocks on macOS despite the flag, so
we now avoid the socket fast path unless the socket is already
non-blocking.

## Changes

- Adds `memoryCost()` and `estimatedSize()` implementations across shell
AST nodes, interpreter, and I/O structures
- Reports estimated memory size to JavaScriptCore GC via
`vm.heap.reportExtraMemoryAllocated()`
- Fixes missing `this.args.deinit()` call in interpreter finalization
- Fixes `BabyList.memoryCost()` to return bytes, not element count
- Conditionally uses socket fast path in IOWriter based on platform and
socket state

## Test plan

- [x] New test: `shell-leak-args.test.ts` - validates memory doesn't
leak during parsing/execution
- [x] New test: `shell-blocking-pipe.test.ts` - validates large pipe
writes don't block the main thread
- [x] Existing shell tests pass

e63a897c66 Add debug logging for test execution with BUN_DEBUG_jest=1 (#23796)
## Summary

Adds debug logging that prints the name of each test when it starts
running, controlled by the `BUN_DEBUG_jest=1` environment variable.

## Changes

- Modified `src/bun.js/test/Execution.zig` to add logging in the
`onEntryStarted()` function
- Added a scoped logger using `bun.Output.scoped(.jest, .visible)`
- When `BUN_DEBUG_jest=1` is set, prints: `[jest] Running test: <test
name>`

## Testing

Manually tested with various test files:

**Without BUN_DEBUG_jest:**
```
$ bun bd test /tmp/test-jest-log.test.ts
bun test v1.3.1 (642d04b9)

 3 pass
 0 fail
 3 expect() calls
Ran 3 tests across 1 file. [2.90s]
```

**With BUN_DEBUG_jest=1:**
```
$ BUN_DEBUG_jest=1 bun bd test /tmp/test-jest-log.test.ts
bun test v1.3.1 (642d04b9)
[jest] Running test: first test
[jest] Running test: second test
[jest] Running test: third test

 3 pass
 0 fail
 3 expect() calls
Ran 3 tests across 1 file. [2.77s]
```

Also tested with nested describe blocks and all test names are logged
correctly.

## Notes

- This feature is only available in debug builds (not release builds)
- No tests were added as this is a debug-only feature
- Helps with debugging test execution flow and understanding when tests
start running

576b21f2ff fix(test): prevent integer overflow in pretty_format writeIndent (#23843)
## Summary

Fixes a panic that occurred when formatting deeply nested objects with
many properties in test output.

## Problem

The `writeIndent()` function in `pretty_format.zig:648` performed
`written * 2` which triggered integer overflow checking in debug builds
when formatting complex nested structures.

**Original crash:**
```
panic: integer overflow
writeIndent at bun.js/test/pretty_format.zig:648
```

**Platform:** Windows x86_64_baseline, Bun v1.3.0

## Solution

Changed from:
```zig
try writer.writeAll(buf[0 .. written * 2]);
```

To:
```zig
const byte_count = @min(buf.len, written *% 2);
try writer.writeAll(buf[0..byte_count]);
```

- Used wrapping multiplication (`*%`) to prevent overflow panic
- Added bounds checking with `@min(buf.len, ...)` for safety
- Maintains correct behavior while preventing crashes

## Test

Added regression test at
`test/js/bun/test/pretty-format-overflow.test.ts` that:
- Creates deeply nested objects (500 levels with 50 properties each)
- Verifies no panic/overflow/crash occurs when formatting
- Uses exact configuration that triggered the original crash

## Verification

-  Test passes with the fix
-  Test would crash without the fix (in debug builds)
-  No changes to behavior, only safety improvement

de4a5a07b1 fix(bundler): import.meta.url and esm wrapper fixes (#23803)
### What does this PR do?
Fixes printing `import.meta.url` and others with `--bytecode`. Fixes
#14954.

Fixes printing `__toESM` when output module format is CJS and input
module format is ESM.

The key change is that `__toESM`'s `isNodeMode` parameter now depends on
the **input module type** (whether the importing file uses ESM syntax
like `import`/`export`) rather than the output format. This matches
Node.js ESM behavior where importing CommonJS from `.mjs` files always
wraps the entire `module.exports` object as the default export, ignoring
`__esModule` markers.

### How did you verify your code works?

Added comprehensive test suite in `test/bundler/bundler_cjs.test.ts`
with **23 tests** covering:

#### Core Behaviors:
-  Files using `import` syntax always get `isNodeMode=1`, which
**ignores `__esModule`** markers and wraps the entire CJS module as
default
-  This matches Node.js ESM semantics for importing CJS from `.mjs`
files
-  Different CJS export patterns (`exports.x`, `module.exports = ...`,
functions, primitives)
-  Named, default, and namespace (`import *`) imports
-  Different targets (node, browser, bun) - all behave the same
-  Different output formats (esm, cjs) - format doesn't affect the
behavior
-  `.mjs` files re-exporting from `.cjs`
-  Deep re-export chains
-  Edge cases (non-boolean `__esModule`, `__esModule=false`, etc.)

#### Test Results:
- **With this PR's changes**: All 23 tests pass 
- **Without this PR (system bun)**: 22 pass, 1 fails (the one testing
that `__esModule` is ignored with import syntax + CJS format)

The failing test with system bun demonstrates the bug being fixed:
currently, format=cjs with import syntax still respects `__esModule`,
but it should ignore it (matching Node.js behavior).

b867969e2c Remove unused EventLoopTimer.Arm return type (#23765)
## Summary

The `EventLoopTimer.Arm` result from `EventLoopTimer.fire()` was being
ignored at both call sites. This PR removes the unused return type and
simplifies the code.

## Changes

- Changed `EventLoopTimer.fire()` to return `void` instead of `Arm`
- Updated all 15 timer callback functions to return `void`
- Removed the `Arm` type definition
- Simplified the `drainTimers()` loop that was ignoring the return value
- Updated both call sites in `Timer.zig`

## Details

The `.rearm` functionality was unused - timers that need to reschedule
themselves (like DNS resolver) handle this by calling
`addTimer()`/`update()` directly rather than relying on the return
value.

This change removes:
- The `Arm` union enum type (3 lines)
- All `return .disarm` and `return .{ .rearm = ... }` statements
- The switch statement in `drainTimers()` that did nothing with the
return value

Net result: **-58 lines** of dead code removed.

## Testing

- [x] Bun builds successfully with `bun bd`

2ebf6c16b6 Fix bounds check in Buffer writeBigInt64/writeBigUInt64 methods (#23781)
## Summary

Fixed an unsigned integer underflow in the bounds check for
`writeBigInt64LE`, `writeBigInt64BE`, `writeBigUInt64LE`, and
`writeBigUInt64BE` methods.

## Problem

When `byteLength < 8`, the bounds check `offset > byteLength - 8` would
cause unsigned integer underflow (since both are `size_t`), resulting in
a large positive number that would pass the check. This allowed
out-of-bounds writes and caused ASAN use-after-poison errors.

**Reproduction:**
```js
const buf = Buffer.from("Hello World");
const slice = buf.slice(0, 5);
slice.writeBigUInt64BE(4096n, 10000); // ASAN error!
```

## Solution

Added an explicit `byteLength < 8` check before the subtraction to
prevent the underflow. The fix is applied to all four functions:
- `writeBigInt64LE` (src/bun.js/bindings/JSBuffer.cpp:2464)
- `writeBigInt64BE` (src/bun.js/bindings/JSBuffer.cpp:2504)
- `writeBigUInt64LE` (src/bun.js/bindings/JSBuffer.cpp:2543)
- `writeBigUInt64BE` (src/bun.js/bindings/JSBuffer.cpp:2582)

## Test plan

- Added comprehensive regression tests covering all edge cases
- Verified the original reproduction case now throws a proper RangeError
instead of crashing
- All tests pass

6ee9dac50f Fix URLSearchParams.toJSON() assertion failure with numeric string keys (#23785)
## Summary

Fixes an assertion failure that occurred when `URLSearchParams.toJSON()`
was called with numeric string keys.

## The Problem

When using numeric string keys (e.g., `"39208"`, `"0"`, `"100"`),
calling `toJSON()` would trigger:
```
ASSERTION FAILED: !parseIndex(propertyName)
cache/webkit-6d0f3aac0b817cc0/include/JavaScriptCore/JSObjectInlines.h:444
```

Reproduction:
```javascript
const params = new URLSearchParams();
params.set("39208", "updated");
params.toJSON(); // crashes
```

## Root Cause

The `getInternalProperties` function in `JSURLSearchParams.cpp` was
using `putDirect()` to add properties to the result object. However,
`putDirect()` cannot be used with property names that can be parsed as
array indices - JSC expects such properties to use indexed storage
instead.

## The Fix

- Replace `putDirect()` with `putDirectMayBeIndex()`, which
automatically handles both regular properties and numeric indices
- Replace `getDirect()` with `get()` to properly retrieve values for
both types of properties

## Test Plan

Added comprehensive tests to `test/js/web/html/URLSearchParams.test.ts`:
-  Single numeric string keys
-  Multiple numeric keys
-  Mixed numeric and non-numeric keys  
-  Duplicate numeric keys
-  Extra arguments (original crash case)

All tests pass, and the original crash no longer occurs.

1abfc0ea24 fix: panic when overriding Set/Map size property with non-numeric value (#23787)
## Summary

Fixes a panic that occurred when `console.log()` tried to format a Set
or Map instance with a non-numeric `size` property.

## Issue

When a Set or Map subclass overrides the `size` property with a
non-numeric value (like a constructor function, string, or other
object), calling `console.log()` on the instance would trigger a panic:

```javascript
class C1 extends Set {
    constructor() {
        super();
        Object.defineProperty(this, "size", {
            writable: true,
            enumerable: true,
            value: Set
        });
        console.log(this); // panic!
    }
}
new C1();
```

## Root Cause

In `src/bun.js/ConsoleObject.zig`, the Map and Set formatting code
called `toInt32()` directly on the `size` property value. This function
asserts that the value is not a Cell (objects/functions), causing a
panic when `size` was overridden with non-numeric values.

## Solution

Changed both Map and Set formatting to use `coerce(i32, globalThis)`
instead of `toInt32()`. This properly handles non-numeric values using
JavaScript's standard type coercion rules and propagates any coercion
errors appropriately.

## Test Plan

Added regression tests to `test/js/bun/util/inspect.test.js` that verify
Set and Map instances with overridden non-numeric `size` properties can
be inspected without panicking.

642d04b9f2 Add --pass-with-no-tests flag to test runner (#23424)
## Summary

This PR adds support for the `--pass-with-no-tests` CLI flag to the test
runner, addressing issue #20814.

With the latest v1.2.8 release, the test runner now fails when no tests
match a filter. While this is useful for agentic coding workflows, there
are legitimate cases where the previous behavior is preferred, such as
in monorepos where a standard test file pattern is used as a filter but
not all packages contain tests.

This flag makes the test runner behave like Jest and Vitest, exiting
with code 0 when no tests are found.

## Changes

- Added `--pass-with-no-tests` flag to CLI arguments in
`src/cli/Arguments.zig`
- Added `pass_with_no_tests` field to `TestOptions` struct in
`src/cli.zig`
- Updated test runner logic in `src/cli/test_command.zig` to respect the
flag
- Added comprehensive tests in
`test/cli/test/pass-with-no-tests.test.ts`

## Test Plan

All new tests pass:
-  `--pass-with-no-tests` exits with 0 when no test files found
-  `--pass-with-no-tests` exits with 0 when filters match no tests
-  Without flag, still exits with 1 when no tests found (preserves
existing behavior)
-  `--pass-with-no-tests` still fails when actual tests fail

Closes #20814

bad726f943 fix(watcher): handle vim atomic save race on macOS (#23566)
## Summary

Fixes a race condition on macOS where editing the entrypoint with vim's
atomic save causes "Module not found" errors during hot reload.

## Root Cause

On macOS, kqueue watches file descriptors/inodes, not paths. Vim's
atomic save sequence:
1. Rename `a.js` to `a.js~` → kqueue reports `NOTE_RENAME` on watched fd
2. Hot reloader immediately triggers reload
3. New file hasn't been created yet → `ENOENT` error
4. Vim re-creates `a.js`, and writes file contents into it
5. Directory gets `NOTE_WRITE` but file already removed from watchlist

```
rename("a.js", "a.js~")                 = 0
openat(AT_FDCWD, "a.js", O_WRONLY|O_CREAT, 0664) = 3
ftruncate(3, 0)                         = 0
write(3, "foobar\n", 7)                 = 7
close(3)                                = 0
```

This is macOS-specific because:
- **kqueue**: watches inodes, fd becomes stale when inode deleted
- **inotify (Linux)**: watches paths, gets `IN.MOVED_TO` (not
`IN.MOVE_SELF`), so files stay in watchlist

## Solution

When the entrypoint receives `NOTE_RENAME` on macOS:
1. Set `is_waiting_for_dir_change` flag
2. Skip immediate reload
3. Wait for parent directory `NOTE_WRITE` event
4. Use `faccessat()` to verify file exists
5. Trigger reload

This only applies to the entrypoint because dependencies have buffering
time during import graph traversal.

## Test Plan

Manual testing with vim on macOS:
1. Run `bun --hot entrypoint.js`
2. Edit entrypoint with vim (`:w`)
3. Verify no "Module not found" errors
4. Verify hot reload succeeds

dc36d5601c Improve FFI error messages when symbol is missing ptr field (#23585)
### What does this PR do?

Fixes unhelpful FFI error messages that made debugging extremely
difficult. The user reported that when dlopen fails, the error doesn't
tell you which library failed or why.

**Before:**
```
Failed to open library. This is usually caused by a missing library or an invalid library path.
```

**After:**
```
Failed to open library "libnonexistent.so": /path/libnonexistent.so: cannot open shared object file: No such file or directory
```

### How did you verify your code works?

1. **Cross-platform compilation verified**
- Ran `bun run zig:check-all` - all platforms compile successfully
(Windows, macOS x86_64/arm64, Linux x86_64/arm64 glibc/musl)

2. **Added comprehensive regression tests**
(`test/regression/issue/dlopen-missing-symbol-error.test.ts`)
   -  Tests dlopen error shows library name when it can't be opened
   -  Tests dlopen error shows symbol name when symbol isn't found
   -  Tests linkSymbols shows helpful error when ptr is missing
   -  Tests handle both glibc and musl libc systems

3. **Manually tested error messages**
   - Missing library: Shows full path and "No such file or directory"
   - Invalid library: Shows "invalid ELF header"
   - Missing symbol: Shows symbol and library name
   - linkSymbols without ptr: Shows helpful explanation

### Implementation Details

1. **Created cross-platform getDlError() helper**
(src/bun.js/api/ffi.zig:8-21)
- On POSIX: Calls `std.c.dlerror()` to get actual system error message
- On Windows: Returns generic message (detailed errors handled in C++
layer via `GetLastError()` + `FormatMessageW()`)
- Follows the pattern established in `BunProcess.cpp` for dlopen error
handling

2. **Improved error messages**
   - dlopen errors now include library name and system error details
   - linkSymbols errors explain the ptr field requirement clearly
   - Symbol lookup errors already showed both symbol and library name

3. **Fixed linkSymbols error propagation** (src/js/bun/ffi.ts:529)
   - Added missing `if (Error.isError(result)) throw result;` check
   - Now consistent with dlopen which already had this check

### Example Error Messages

- **Missing library:** `Failed to open library "libnonexistent.so":
cannot open shared object file: No such file or directory`
- **Invalid library:** `Failed to open library "/etc/passwd": invalid
ELF header`
- **Missing symbol:** `Symbol "nonexistent_func" not found in
"libc.so.6"`
- **Missing ptr:** `Symbol "myFunc" is missing a "ptr" field. When using
linkSymbols() or CFunction()...`

bd88717ddc codegen: Add WriteBarrierEarlyInit support for classes with values and valuesArray (#23624)
## Summary

Adds comprehensive support to `generate-classes.ts` for JavaScript
classes that need both named WriteBarrier members (like callbacks) and a
dynamic array of JSValues, all properly tracked by the garbage
collector. This replaces error-prone manual `protect()/unprotect()`
calls with proper GC integration.

## Motivation

The shell interpreter was using `JSValue.protect()/unprotect()` to keep
JavaScript objects alive, which caused memory leaks when cleanup paths
didn't properly unprotect values. This is a common pattern that needed a
better solution.

## What Changed

### Code Generator (`generate-classes.ts`)

When a class has both `values: ["resolve", "reject"]` and `valuesArray:
true`:

**Generated C++ class gets:**
- `WTF::FixedVector<JSC::WriteBarrier<JSC::Unknown>> jsvalueArray`
member for dynamic array
- Individual `JSC::WriteBarrier<JSC::Unknown> m_resolve, m_reject`
members for named values
- 4 `create()` overloads covering all combinations:
  1. Basic: `create(vm, globalObject, structure, ptr)`
  2. Array only: `create(..., FixedVector<WriteBarrier<Unknown>>&&)`
  3. Named values: `create(..., JSValue resolve, JSValue reject)` 
  4. Both: `create(..., FixedVector&&, JSValue resolve, JSValue reject)`

**Constructor overloads using `WriteBarrierEarlyInit`:**
```cpp
JSShellInterpreter(VM& vm, Structure* structure, void* ptr, 
                   JSValue resolve, JSValue reject)
    : Base(vm, structure)
    , m_resolve(resolve, JSC::WriteBarrierEarlyInit)  // ← Key technique
    , m_reject(reject, JSC::WriteBarrierEarlyInit)
{
    m_ctx = ptr;
}
```

The `WriteBarrierEarlyInit` tag allows initializing WriteBarriers in the
constructor initializer list before the object is fully constructed,
which is required for proper GC integration.

**Extern C bridge functions:**
- `TypeName__createWithValues(globalObject, ptr, markedArgumentBuffer*)`
- `TypeName__createWithInitialValues(globalObject, ptr, resolve,
reject)`
- `TypeName__createWithValuesAndInitialValues(globalObject, ptr,
buffer*, resolve, reject)`

**Zig convenience wrappers:**
- `toJSWithValues(this, globalObject, markedArgumentBuffer)`
- `toJSWithInitialValues(this, globalObject, resolve, reject)`
- `toJSWithValuesAndInitialValues(this, globalObject, buffer, resolve,
reject)`

### Shell Interpreter Memory Leak Fix

**Before:**
```zig
const js_value = JSShellInterpreter.toJS(interpreter, globalThis);
resolve.protect();  // Manual reference counting
reject.protect();
// ... later in cleanup ...
resolve.unprotect();  // Easy to forget/miss in error paths
reject.unprotect();
```

**After:**
```zig
const js_value = Bun__createShellInterpreter(
    globalThis, 
    interpreter,
    parsed_shell_script,
    resolve,  // Stored with WriteBarrierEarlyInit
    reject,   // GC tracks automatically
);
// No manual memory management needed!
```

### Supporting Changes

- Added `MarkedArgumentBuffer.wrap()` helper in Zig for safe
MarkedArgumentBuffer usage
- Created `ShellBindings.cpp` with `Bun__createShellInterpreter()` using
the new API
- Removed all `protect()/unprotect()` calls from shell interpreter
- Applied pattern to both `ShellInterpreter` and `ShellArgs` classes

## Benefits

1. **No memory leaks**: GC tracks all references automatically
2. **Safer**: Cannot forget to unprotect values
3. **Cleaner code**: No manual reference counting
4. **Reusable**: Pattern works for any class needing to store JSValues
5. **Performance**: Same cost as manual protect/unprotect but safer

## Testing

Existing shell tests verify the functionality. The pattern is already
used throughout JavaScriptCore for similar cases (see
`JSWrappingFunction`, `AsyncContextFrame`, `JSModuleMock`, etc.)

## When to Use This Pattern

Use `values` + `valuesArray` + `WriteBarrierEarlyInit` when:
- Your C++ class needs to keep JavaScript values alive
- You have both known named callbacks AND dynamic arrays of values
- You want the GC to track references instead of manual
protect/unprotect
- Your class extends `JSDestructibleObject`

0c79e5e0dd Fix race condition in BunFrontendDevServer HMR WebSocket tests (#23625)
## Summary

Fixes flaky tests in `test/cli/inspect/BunFrontendDevServer.test.ts` by
resolving a race condition where tests would miss the `clientConnected`
event.

## Problem

Two tests were failing intermittently (~30% failure rate):
- `should notify on clientNavigated events`
- `should notify on consoleLog events`

Both tests would timeout after 5000ms waiting for the `clientConnected`
event that never arrived.

## Root Cause

In `src/bake/DevServer/HmrSocket.zig:30-41`, when a WebSocket connection
opens, the `onOpen()` handler immediately sends the `clientConnected`
inspector event.

The flaky tests had this problematic sequence:
1. Create WebSocket with `await createHMRClient()`
2. Server's `onOpen()` fires instantly and emits `clientConnected` event
3. Test then calls
`session.waitForEvent("BunFrontendDevServer.clientConnected")`
4. **Race condition**: Event already sent, test waits forever and times
out

## Solution

Set up event listeners **before** creating the WebSocket connection,
matching the pattern from the working test "should receive
clientConnected and clientDisconnected events":

```typescript
// Set up listener FIRST
const connectedEventPromise = session.waitForEvent("BunFrontendDevServer.clientConnected");

// Then create WebSocket
const ws = await createHMRClient();

// Now await the event
const connectedEvent = await connectedEventPromise;
```

## Testing

Verified with 30 consecutive test runs:
- **Before fix**: ~30% failure rate
- **After fix**: 100% pass rate (30/30 passes)

Tested with both:
- Debug build: `bun bd test` 
- System bun v1.3.0: `bun test`

caa4f54b2e refactor: move ReadableStream-related functions from ZigGlobalObject.cpp to ReadableStream.cpp (#23547)
## Summary

This PR moves all ReadableStream-related functions from
`ZigGlobalObject.cpp` to `ReadableStream.cpp` for better code
organization and maintainability.

## Changes

Moved 17 functions from `ZigGlobalObject.cpp` to `ReadableStream.cpp`:

### Core ReadableStream Functions
- `ReadableStream__tee` - with `invokeReadableStreamFunction` helper
(converted to lambda)
- `ReadableStream__cancel`
- `ReadableStream__detach`
- `ReadableStream__isDisturbed`
- `ReadableStream__isLocked`
- `ReadableStreamTag__tagged`

### Stream Creation & Conversion
- `ZigGlobalObject__createNativeReadableStream`
- `ZigGlobalObject__readableStreamToArrayBufferBody`
- `ZigGlobalObject__readableStreamToArrayBuffer`
- `ZigGlobalObject__readableStreamToBytes`
- `ZigGlobalObject__readableStreamToText`
- `ZigGlobalObject__readableStreamToFormData`
- `ZigGlobalObject__readableStreamToJSON`
- `ZigGlobalObject__readableStreamToBlob`

### Host Functions
- `functionReadableStreamToArrayBuffer`
- `functionReadableStreamToBytes`

## Technical Details

### File Changes
- **ReadableStream.cpp**: Added necessary includes and all
ReadableStream functions
- **ReadableStream.h**: Added forward declarations for code generator
functions
- **ZigGlobalObject.cpp**: Removed moved functions (394 lines removed)

### Implementation Notes
- Added proper namespace declarations (`using namespace JSC; using
namespace WebCore;`) to all extern "C" functions
- Used correct namespace qualifiers for types (e.g., `Bun::IDLRawAny`,
`Bun::AbortError`)
- Added required includes: `WebCoreJSBuiltins.h`, `ZigGlobalObject.h`,
`ZigGeneratedClasses.h`, `helpers.h`, `BunClientData.h`,
`BunIDLConvert.h`

## Testing

-  Builds successfully with debug configuration
-  All functions maintain identical behavior
-  No API changes

## Benefits

1. **Better code organization**: ReadableStream functionality is now
consolidated in one place
2. **Improved maintainability**: Easier to find and modify
ReadableStream-related code
3. **Reduced file size**: `ZigGlobalObject.cpp` is now ~400 lines
smaller

f00e1816ef Fix crash handler not dumping stack traces on Linux aarch64 (#23549)
### What does this PR do?

Fixes the crash handler failing to capture and display stack traces on
Linux ARM64 systems.

**Before:**
```
============================================================
panic(main thread): cast causes pointer to be null
```
No stack trace shown.

**After:**
```
============================================================
panic(main thread): cast causes pointer to be null
bun.js.api.FFIObject.Reader.u8
/workspace/bun/src/bun.js/api/FFIObject.zig:67:41

bun.js.jsc.host_fn.toJSHostCall__anon_2545765
/workspace/bun/src/bun.js/jsc/host_fn.zig:93:5
```
Full stack trace with source locations.

#### Root Cause
- Zig's `std.debug.captureStackTrace` uses `StackIterator.init()` which
falls back to frame pointer-based unwinding when no context is provided
- Frame pointer-based unwinding doesn't work reliably on ARM64, even
with `-fno-omit-frame-pointer` enabled
- This resulted in 0 frames being captured (`trace.index == 0`)

#### Changes
1. **Use glibc's backtrace() on Linux**: On Linux with glibc (not musl),
always use glibc's `backtrace()` function instead of Zig's
StackIterator. glibc's implementation properly uses DWARF unwinding
information from `.eh_frame` sections.

2. **Skip crash handler frames**: After capturing with `backtrace()`,
find the desired `begin_addr` in the trace (within 128 byte tolerance)
and filter out crash handler internal frames for cleaner output. If
`begin_addr` is not found, use the complete backtrace.

3. **Preserve existing behavior**:
   - Non-debug builds: Use WTF printer (fast, no external deps)
- Debug builds: Fall through to llvm-symbolizer (detailed source info)

### How did you verify your code works?

Reproduced the crash:
```bash
bun-debug --print 'Bun.FFI.read.u8(0)'
```

Verified that:
-  Stack traces now appear on Linux ARM64 with proper source locations
-  Crash handler frames are properly filtered out

356d0e491c fix: use std::call_once for thread-safe JSC initialization (#23542)
## What does this PR do?

Fixes a race condition where multiple threads could attempt to
initialize JavaScriptCore concurrently when the bundler's thread pool
processes files with macros.

Fixes #23540

## How did you verify your code works?

Reproduced the segfault with the Brisa project build and verified the
fix resolves it:

```bash
git clone https://github.com/brisa-build/brisa
cd brisa
bun install
bun run build
```

Before the fix: Segmentation fault with assertion failure
After the fix: Build proceeds without crashing

## Root Cause

The previous implementation used a simple boolean flag `has_loaded_jsc`
without synchronization. When multiple bundler threads tried to execute
macros simultaneously, they could race through the initialization check
before `JSC::initialize()` finished finalizing options on another
thread.

This caused crashes with:
```
ASSERTION FAILED: g_jscConfig.options.allowUnfinalizedAccess || g_jscConfig.options.isFinalized
vendor/WebKit/Source/JavaScriptCore/runtime/Options.h(146) : static OptionsStorage::Bool &JSC::Options::forceTrapAwareStackChecks()
```

## The Fix

Replace the boolean flag with `std::call_once`, which provides:
- Thread-safe initialization
- Guaranteed exactly-once execution
- Proper memory barriers to ensure visibility across threads

The initialization code is now wrapped in a lambda passed to
`std::call_once`, capturing the necessary parameters (`evalMode`,
`envp`, `envc`, `onCrash`).

755b41e85b Add BUN_WATCHER_TRACE environment variable for debugging file watcher events (#23533)
## Summary

Adds `BUN_WATCHER_TRACE` environment variable that logs all file watcher
events to a JSON file for debugging. When set, the watcher appends
detailed event information to the specified file path.

## Motivation

Debugging watch-related issues (especially with `bun --watch` and `bun
--hot`) can be difficult without visibility into what the watcher is
actually seeing. This feature provides detailed trace logs showing
exactly which files are being watched and what events are triggered.

## Implementation

- **Isolated module** (`src/watcher/WatcherTrace.zig`) - All trace logic
in separate file
- **No locking needed** - Watcher runs on its own thread, no mutex
required
- **Append-only mode** - Traces persist across multiple runs for easier
debugging
- **Silent errors** - Won't break functionality if trace file can't be
created
- **JSON format** - Easy to parse and analyze

## Usage

```bash
BUN_WATCHER_TRACE=/tmp/watch.log bun --watch script.js
BUN_WATCHER_TRACE=/tmp/hot.log bun --hot server.ts
```

## JSON Output Format

Each line is a JSON object with:
```json
{
  "timestamp": 1760280923269,
  "index": 0,
  "path": "/path/to/watched/file.js",
  "delete": false,
  "write": true,
  "rename": false,
  "metadata": false,
  "move_to": false,
  "changed_files": ["script.js"]
}
```

## Testing

All tests use stdout streaming to wait for actual reloads (no
sleeps/timeouts):
- Tests with `--watch` flag
- Tests with `fs.watch` API  
- Tests that trace file appends across multiple runs
- Tests validation of JSON format and event details

```
 4 pass
 0 fail
📊 52 expect() calls
```

## Files Changed

- `src/Watcher.zig` - Minimal integration with WatcherTrace module
- `src/watcher/WatcherTrace.zig` - New isolated trace implementation
- `src/watcher/KEventWatcher.zig` - Calls writeTraceEvents before
onFileUpdate
- `src/watcher/INotifyWatcher.zig` - Calls writeTraceEvents before
onFileUpdate
- `src/watcher/WindowsWatcher.zig` - Calls writeTraceEvents before
onFileUpdate
- `test/cli/watch/watcher-trace.test.ts` - Comprehensive tests

robobun
5bdc32265d Add support for localAddress and localPort in TCP connections (#23464)
## Summary

This PR implements support for `localAddress` and `localPort` options in
TCP connections, allowing users to bind outgoing connections to a
specific local IP address and port.

This addresses issue #6888 and implements Node.js-compatible behavior
for these options.

## Changes

### C Layer (uSockets)
- **`bsd.c`**: Modified `bsd_create_connect_socket()` to accept a
`local_addr` parameter and call `bind()` before `connect()` when a local
address is specified
- **`context.c`**: Updated `us_socket_context_connect()` and
`start_connections()` to parse and pass local address parameters through
the connection flow
- **`libusockets.h`**: Updated public API signatures to include
`local_host` and `local_port` parameters
- **`internal.h`**: Added `local_host` and `local_port` fields to
`us_connecting_socket_t` structure
- **`openssl.c`**: Updated SSL connection function to match the new
signature

### Zig Layer
- **`SocketContext.zig`**: Updated `connect()` method to accept and pass
through `local_host` and `local_port` parameters
- **`socket.zig`**: Modified `connectAnon()` to handle local address
binding, including IPv6 bracket removal and proper memory management
- **`Handlers.zig`**: Added `localAddress` and `localPort` fields to
`SocketConfig` and implemented parsing from JavaScript options
- **`Listener.zig`**: Updated connection structures to store and pass
local binding information
- **`socket.zig` (bun.js/api/bun)**: Modified `doConnect()` to extract
and pass local address options
- Updated all other call sites (HTTP, MySQL, PostgreSQL, Valkey) to pass
`null, 0` for backward compatibility

### JavaScript Layer
- **`net.ts`**: Enabled `localAddress` and `localPort` support by
passing these options to `doConnect()` and removing TODO comments

### Tests
- **`06888-localaddress.test.ts`**: Added comprehensive tests covering:
  - IPv4 local address binding
  - IPv4 local address and port binding
  - IPv6 local address binding (loopback)
  - Backward compatibility (connections without local address)

## Test Results

All tests pass successfully:
```
✓ TCP socket can bind to localAddress - IPv4
✓ TCP socket can bind to localAddress and localPort - IPv4
✓ TCP socket can bind to localAddress - IPv6 loopback
✓ TCP socket without localAddress works normally

4 pass, 0 fail
```

## API Usage

```typescript
import net from "net";

// Connect with a specific local address
const client = net.createConnection({
  host: "example.com",
  port: 80,
  localAddress: "192.168.1.100",  // Bind to this local IP
  localPort: 0,                    // Let system assign port (optional)
});
```

## Implementation Details

The implementation follows the same flow as Node.js:
1. JavaScript options are parsed in `Handlers.zig` 
2. Local address/port are stored in the connection configuration
3. The Zig layer processes and passes them to the C layer
4. The C layer parses the local address and calls `bind()` before
`connect()`
5. Both IPv4 and IPv6 addresses are supported

Memory management is handled properly throughout the stack, with
appropriate allocation/deallocation at each layer.

Closes #6888

525315cf39 fix: include cookies in WebSocket upgrade response (#23499)
Fixes #23474

## Summary

When `request.cookies.set()` is called before `server.upgrade()`, the
cookies are now properly included in the WebSocket upgrade response
headers.

## Problem

Previously, cookies set on the request via `req.cookies.set()` were only
written for regular HTTP responses but were ignored during WebSocket
upgrades. Users had to manually pass cookies via the `headers` option:

```js
server.upgrade(req, {
  headers: {
    "Set-Cookie": `SessionId=${sessionId}`,
  },
});
```

## Solution

Modified `src/bun.js/api/server.zig` to check for and write cookies to
the WebSocket upgrade response after the "101 Switching Protocols"
status is set but before the actual upgrade is performed.

The fix handles both cases:
- When `upgrade()` is called without custom headers
- When `upgrade()` is called with custom headers

## Testing

Added comprehensive regression tests in
`test/regression/issue/23474.test.ts` that:
- Verify cookies are set in the upgrade response without custom headers
- Verify cookies are set in the upgrade response with custom headers
- Use `Promise.withResolvers()` for efficient async handling (no
arbitrary timeouts)

Tests confirmed:
-  Fail with system bun v1.2.23 (without fix)
-  Pass with debug build v1.3.0 (with fix)

## Manual verification

```bash
curl -i -H "Connection: Upgrade" -H "Upgrade: websocket" \
  -H "Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==" \
  -H "Sec-WebSocket-Version: 13" \
  http://localhost:3000/ws
```

Response now includes:
```
HTTP/1.1 101 Switching Protocols
Set-Cookie: test=123; Path=/; SameSite=Lax
Upgrade: websocket
Connection: Upgrade
...
```

012a2bab92 Fix Clang 19 detection in Nix flake by setting CMAKE compiler variables (#23445)
## Summary

Fixes Clang 19 detection in the Nix flake environment by explicitly
setting CMAKE compiler environment variables in the shellHook.

## Problem

When using `nix develop` or `nix print-dev-env`, CMake was unable to
detect the Clang 19 compiler because the `CMAKE_C_COMPILER` and
`CMAKE_CXX_COMPILER` environment variables were not being set, even
though the compiler was available in the environment.

The `shell.nix` file correctly sets these variables (lines 80-87), but
`flake.nix` was missing them.

## Solution

Updated `flake.nix` shellHook to export the same compiler environment
variables as `shell.nix`:
- `CC`, `CXX`, `AR`, `RANLIB` 
- `CMAKE_C_COMPILER`, `CMAKE_CXX_COMPILER`, `CMAKE_AR`, `CMAKE_RANLIB`

This ensures consistent compiler detection across both Nix entry points
(`nix develop` with flakes and `nix-shell` with shell.nix).

## Testing

Verified that all compiler variables are now properly set:
```bash
nix develop --accept-flake-config --impure --command bash -c 'echo "CMAKE_C_COMPILER=$CMAKE_C_COMPILER"'
# Output: CMAKE_C_COMPILER=/nix/store/.../clang-wrapper-19.1.7/bin/clang
```

Also tested with the profile workflow:
```bash
nix develop --accept-flake-config --impure --profile ./dev-profile --command true
eval "$(nix print-dev-env ./dev-profile --accept-flake-config --impure)"
echo "CMAKE_C_COMPILER=$CMAKE_C_COMPILER"
# Output: CMAKE_C_COMPILER=/nix/store/.../clang
```

8197a5f7af Fix WriteBarrier initialization to use WriteBarrierEarlyInit (#23435)
## Summary

This PR fixes incorrect WriteBarrier initialization patterns throughout
the Bun codebase where `.set()` or `.setEarlyValue()` was being called
in the constructor body or in `finishCreation()`. According to
JavaScriptCore's `WriteBarrier.h`, WriteBarriers that are initialized
during construction should use the `WriteBarrierEarlyInit` constructor
in the initializer list to avoid triggering unnecessary write barriers.

## Changes

The following classes were updated to properly initialize WriteBarrier
fields:

1. **InternalModuleRegistry** - Initialize internal fields in
constructor using `setWithoutWriteBarrier()` instead of calling `.set()`
in `finishCreation()`
2. **AsyncContextFrame** - Pass callback and context to constructor and
use `WriteBarrierEarlyInit`
3. **JSCommonJSModule** - Pass id, filename, dirname to constructor and
use `WriteBarrierEarlyInit`
4. **JSMockImplementation** - Pass initial values to constructor and use
`WriteBarrierEarlyInit`
5. **JSConnectionsList** - Pass connection sets to constructor and use
`WriteBarrierEarlyInit`
6. **JSBunRequest** - Pass params to constructor and initialize both
`m_params` and `m_cookies` using `WriteBarrierEarlyInit`
7. **JSNodeHTTPServerSocket** - Initialize `currentResponseObject` using
`WriteBarrierEarlyInit` instead of calling `setEarlyValue()`

## Why This Matters

From JavaScriptCore's `WriteBarrier.h`:

```cpp
enum WriteBarrierEarlyInitTag { WriteBarrierEarlyInit };

// Constructor for early initialization during object construction
WriteBarrier(T* value, WriteBarrierEarlyInitTag)
{
    this->setWithoutWriteBarrier(value);
}
```

Using `WriteBarrierEarlyInit` during construction:
- Avoids triggering write barriers when they're not needed
- Is the correct pattern for initializing WriteBarriers before the
object is fully constructed
- Aligns with JavaScriptCore best practices

## Testing

-  Full debug build completes successfully
-  Basic functionality tested (CommonJS modules, HTTP requests, Node
HTTP servers)
-  No regressions observed

## Note on generate-classes.ts

The code generator (`generate-classes.ts`) does not need updates because
generated classes intentionally leave WriteBarrier fields (callbacks,
cached fields, values) uninitialized. They start with
default-constructed WriteBarriers and are populated later by Zig code
via setter functions, which is the correct pattern for those fields.

The problem was ``await Bun.write(join(deepPath, "test.js"),

but it failed before refConcurrently was called and it called
unrefConcurrently after failing. so then when the subprocess spawned it

8826b4f5f5 Fix WTFTimer issues with Atomics.waitAsync (#23442)
## Summary

Fixes two critical issues in `WTFTimer` when `Atomics.waitAsync` creates
multiple timer instances.

## Problems

### 1. Use-After-Free in `WTFTimer.fire()`

**Location:** `/workspace/bun/src/bun.js/api/Timer/WTFTimer.zig:70-82`

```zig
pub fn fire(this: *WTFTimer, _: *const bun.timespec, _: *VirtualMachine) EventLoopTimer.Arm {
    this.event_loop_timer.state = .FIRED;
    this.imminent.store(null, .seq_cst);
    this.runWithoutRemoving();  // ← Callback might destroy `this`
    return if (this.repeat)     // ← UAF: accessing freed memory
        .{ .rearm = this.event_loop_timer.next }
    else
        .disarm;
}
```

When `Atomics.waitAsync` creates a `DispatchTimer` with a timeout, the
timer fires and the callback destroys `this`, but we continue to access
it.

### 2. Imminent Pointer Corruption

**Location:** `/workspace/bun/src/bun.js/api/Timer/WTFTimer.zig:36-42`

```zig
pub fn update(this: *WTFTimer, seconds: f64, repeat: bool) void {
    // Multiple WTFTimers unconditionally overwrite the shared imminent pointer
    this.imminent.store(if (seconds == 0) this else null, .seq_cst);
    // ...
}
```

All `WTFTimer` instances share the same
`vm.eventLoop().imminent_gc_timer` atomic pointer. When multiple timers
are created (GC timer + Atomics.waitAsync timers), they stomp on each
other's imminent state.

## Solutions

### 1. UAF Fix

Read `this.repeat` and `this.event_loop_timer.next` **before** calling
`runWithoutRemoving()`:

```zig
const should_repeat = this.repeat;
const next_time = this.event_loop_timer.next;
this.runWithoutRemoving();
return if (should_repeat)
    .{ .rearm = next_time }
else
    .disarm;
```

### 2. Imminent Pointer Fix

Use compare-and-swap to only set imminent if it's null, and only clear
it if this timer was the one that set it:

```zig
if (seconds == 0) {
    _ = this.imminent.cmpxchgStrong(null, this, .seq_cst, .seq_cst);
    return;
} else {
    _ = this.imminent.cmpxchgStrong(this, null, .seq_cst, .seq_cst);
}
```

## Test Plan

Added regression test at
`test/regression/issue/atomics-waitasync-wtftimer-uaf.test.ts`:

```javascript
const buffer = new SharedArrayBuffer(16);
const view = new Int32Array(buffer);
Atomics.store(view, 0, 0);

const result = Atomics.waitAsync(view, 0, 0, 10);
setTimeout(() => {
  console.log("hi");
}, 100);
```

**Before:** Crashes with UAF under ASAN  
**After:** Runs cleanly

All existing atomics tests pass.

### What does this PR do?
Calls `uncork()` after flushing response headers to ensure data is sent
as soon as possible, improving responsiveness.
This behavior still works correctly even without the explicit `uncork()`
call, due to the deferred uncork logic implemented here:

A test already covers this scenario in

6e3359dd16 Bump version to 1.3.0 (#23401)
## What does this PR do?

Bumps Bun version from 1.2.24 to 1.3.0, marking the start of the 1.3.x
release series.

## Changes

- **`package.json`**: Updated version from `1.2.24` to `1.3.0`
- **`LATEST`**: Updated from `1.2.23` to `1.3.0` (used by installation
scripts)
- **`test/bundler/bundler_bun.test.ts`**: Updated version check to
include `1.3.x` so export conditions tests continue to run

## Verification

 Debug build successful showing version `1.3.0-debug`
 All platforms compile successfully via `bun run zig:check-all` (49/49
steps)
 Bundler tests pass with updated version check

## Additional Notes

- CI workflow Bun versions (e.g., `1.2.3`, `1.2.0` in
`.github/workflows/release.yml`) are intentionally left unchanged -
these are pinned versions used to run the release tooling, not the
version being released
- Docker images use `ARG BUN_VERSION` passed at build time and don't
need updates
- The actual release version comes from git tags via `${{
env.BUN_VERSION }}`

Adds back the `--only` flag. When running `bun test` on a full test
suite, without this flag it will run only that test in its file, but it
will run all other tests from other files. With this flag, it will not
run things from other files.

6875cc3f7b test: refactor bundler_promiseall_deadcode to use itBundled helper (#23370)
## Summary

Modernizes `test/bundler/bundler_promiseall_deadcode.test.ts` to use the
`itBundled` test helper instead of manual temp directory creation and
spawning. This makes the test more concise, maintainable, and consistent
with other bundler tests.

## Changes

- Replace `tempDirWithFiles` + manual `Bun.spawn` with `itBundled`
- Use `files` object for test fixtures instead of creating a temp
directory
- Use `onAfterBundle` callback for bundled output assertions
- Use `run.validate` for runtime stderr validation
- Use `run.partialStdout` for stdout verification
- Preserve all original test assertions and behavior

## Test Results

All 3 tests pass with identical functional behavior:

```
 3 pass
 0 fail
 2 snapshots, 23 expect() calls
Ran 3 tests across 1 file. [8.95s]
```

## Verification

All original assertions are preserved:
-  Build success validation
-  Bundled output snapshots (updated paths to match itBundled format)
-  `__esm` and `__promiseAll` presence/absence checks
-  Runtime execution validation (exit code 0)
-  Runtime stderr validation (no async syntax errors)
-  Runtime stdout validation (contains expected output)

The test is now more concise (407 insertions vs 514 deletions) while
maintaining full test coverage.

767e03ef24 load local bunfig.toml for bun run earlier (for run.bun option) (#16664)
Alternative to #15596 where it now only impacts `bun run` for the same
cwd dir. This does not effect `bunx` ([even though according to code it
should load
it](7830e15650/src/cli.zig (L2597-L2628))),
and isnt as fancy as `bun install` where it ensures to check the bunfig
in `package.json` dir.

This shouldn't have any performance issues because its already loading
the file, but now its loading earlier so it can use `run.bun` option.


Fixes #11445, (as well as fixes #15484, fixes #15483, fixes #17064)

93910f34da Fix bin linking to atomically normalize CRLF in shebang lines (#23360)
## Summary

This PR improves the correctness of bin linking by atomically
normalizing `\r\n` to `\n` in shebang lines when linking bins.

### Changes

- **Refactored shebang normalization in `src/install/bin.zig`**:
  - Extracted logic into separate `tryNormalizeShebang` function
  - Changed from in-place file modification to atomic file replacement
- Reads entire file, creates temporary file with corrected shebang, then
atomically renames
  - Properly cleans up temporary files on errors
  
- **Added test coverage**:
- New test file `test/cli/install/shebang-normalize.test.ts` verifies
CRLF normalization works correctly
- Modified existing test in `bun-link.test.ts` to use Python script with
CRLF shebang

### Why

The previous implementation modified files in-place by seeking to the
`\r` position and overwriting with `\n`. This could potentially corrupt
files if interrupted mid-write. The new atomic approach ensures file
integrity by writing to a temporary file first, then renaming it to
replace the original.

## Test plan

-  `bun bd test test/cli/install/shebang-normalize.test.ts` - passes
-  Verified bins with CRLF shebangs are normalized to LF during linking
-  Code compiles successfully

d3ff6a5e35 Fix process.stdin not receiving data after pause/resume (#23362)
## Summary

Fixed a race condition where calling `pause()` followed by `resume()` on
`process.stdin` would prevent data from being received, causing the
process to exit immediately instead of listening for input.

## Root Cause

The issue was in the pause/resume event handling logic in
`ProcessObjectInternals.ts`:

1. When `pause()` is called, the "pause" event handler schedules a
`disown()` call for the next tick
2. When `resume()` is called immediately after, it calls `own()` to
acquire a stream reader
3. On the next tick, the scheduled `disown()` from step 1 executes and
incorrectly releases the reader that was just acquired in step 2

This race condition left the stream without a reader, so no data could
be received.

## Solution

Added a `pendingDisown` flag that:
- Gets set to `true` when scheduling a disown operation
- Gets cleared to `false` when `own()` is called (during resume)
- Prevents the scheduled disown from executing if it has been cancelled
by a subsequent `own()` call

## Test Plan

- [x] Added regression tests in
`test/regression/issue/stdin-pause-resume.test.ts`
- [x] Verified fix with original reproduction case
- [x] Existing stdin/tty tests still pass
(`tty-readstream-ref-unref.test.ts`,
`tty-reopen-after-stdin-eof.test.ts`)

## Reproduction

Before this fix, the following code would exit immediately:
```ts
process.stdin.on("data", chunk => {
  process.stdout.write(chunk);
});
process.stdin.pause();
process.stdin.resume();
```

After the fix, it correctly waits for and processes input.

5f1ca176cd fix(windows): prevent data loss in pipe reads after libuv 1.51.0 upgrade (#23340)
### What does this PR do?

Fixes data loss when reading large amounts of data from subprocess pipes
on Windows, a regression introduced by the libuv 1.51.0 upgrade in
commit e3783c244f.

### The Problem

When piping large data through a subprocess on Windows (e.g.,
`process.stdin.pipe(process.stdout)`), Bun randomly loses ~73KB of data
out of 1MB, receiving only ~974KB instead of the full 1048576 bytes.

The subprocess correctly receives all 1MB on stdin, but the parent
process loses data when reading from the subprocess stdout.

### Root Cause Analysis

#### libuv 1.51.0 Change

The libuv 1.51.0 upgrade (commit
[libuv/libuv@727ee723](727ee7237e))
changed Windows pipe reading behavior:

**Before:** libuv would call `PeekNamedPipe` to check available bytes,
then read exactly that amount.

**After:** libuv attempts immediate non-blocking reads (up to 65536
bytes) before falling back to async reads. If less data is available
than requested, it returns what's available and signals `more=0`,
causing the read loop to break.

This optimization introduces **0-byte reads** when data isn't
immediately available, which are delivered to Bun's read callback.

#### The Race Condition

When Bun's `WindowsBufferedReader` called `onRead(.drained)` for these
0-byte reads, it created a race condition. Debug logs clearly show the
issue:

**Error case (log.txt):**
```
Line 79-80: onStreamRead = 0 (drained)
Line 81:    filesink closes (stdin closes)
Line 85:    onStreamRead = 6024        ← Should be 74468!
Line 89:    onStreamRead = -4095 (EOF)
```

**Success case (success.log.txt):**
```
Line 79-80: onStreamRead = 0 (drained)
Line 81:    filesink closes (stdin closes)
Line 85:    onStreamRead = 74468       ← Full chunk!
Line 89-90: onStreamRead = 0 (drained)
Line 91:    onStreamRead = 6024
Line 95:    onStreamRead = -4095 (EOF)
```

When stdin closes while a 0-byte drained read is pending, the next read
returns truncated data (6024 bytes instead of 74468 bytes).

### The Fix

Two changes to `WindowsBufferedReader` in `src/io/PipeReader.zig`:

#### 1. Ignore 0-byte reads (line 937-940)

Don't call `onRead(.drained)` for 0-byte reads. Just return and let
libuv queue the next read. This prevents the race condition that causes
truncated reads.

```zig
0 => {
    // With libuv 1.51.0+, calling onRead(.drained) here causes a race condition
    // where subsequent reads return truncated data. Just ignore 0-byte reads.
    return;
},
```

#### 2. Defer `has_inflight_read` flag clearing (line 827-839)

Clear the flag **after** the read callback completes, not before. This
prevents libuv from starting a new overlapped read operation while we're
still processing the current data buffer, which could cause memory
corruption per the libuv commit message:

> "Starting a new read after uv_read_cb returns causes memory corruption
on the OVERLAPPED read_req if uv_read_stop+uv_read_start was called
during the callback"

```zig
const result = onReadChunkFn(this.parent, buf, hasMore);
// Clear has_inflight_read after the callback completes
this.flags.has_inflight_read = false;
return result;
```

### How to Test

Run the modified test in
`test/js/bun/spawn/spawn-stdin-readable-stream.test.ts`:

```js
test("ReadableStream with very large chunked data", async () => {
  const chunkSize = 64 * 1024; // 64KB chunks
  const numChunks = 16; // 1MB total
  const chunk = Buffer.alloc(chunkSize, "x");

  const stream = new ReadableStream({
    pull(controller) {
      if (pushedChunks < numChunks) {
        controller.enqueue(chunk);
        pushedChunks++;
      } else {
        controller.close();
      }
    },
  });

  await using proc = spawn({
    cmd: [bunExe(), "-e", `
      let length = 0;
      process.stdin.on('data', (data) => length += data.length);
      process.once('beforeExit', () => console.error(length));
      process.stdin.pipe(process.stdout)
    `],
    stdin: stream,
    stdout: "pipe",
    env: bunEnv,
  });

  const text = await proc.stdout.text();
  expect(text.length).toBe(chunkSize * numChunks); // Should be 1048576
});
```

**Before fix:** Randomly fails with ~974KB instead of 1MB  
**After fix:** Consistently passes with full 1MB

Run ~100 times to verify the race condition is fixed.

### Related Issues

This may also fix #23071 (Windows scripts hanging), though that issue
needs separate verification.

### Why Draft?

Marking as draft for Windows testing by the team. The fix is based on
detailed debug log analysis showing the exact race condition, but needs
verification on Windows CI.

ed0d932a6d test: show received value in snapshot CI error message (#23352)
## Summary

When a snapshot is created in CI without `--update-snapshots`, the error
message now displays the received value that was attempting to be
snapshotted. This helps developers understand what value triggered the
error.

## Changes

- Modified the `SnapshotCreationNotAllowedInCI` error message in
`src/bun.js/test/expect.zig` to include the received value using the
same formatting pattern as other expect error messages

## Before

```
Snapshot creation is not allowed in CI environments unless --update-snapshots is used
If this is not a CI environment, set the environment variable CI=false to force allow.
```

## After

```
Snapshot creation is not allowed in CI environments unless --update-snapshots is used
If this is not a CI environment, set the environment variable CI=false to force allow.

Received: <formatted value>
```

420d51985b fix(test): prevent AGENTS env var from affecting claudecode-flag test (#23331)
## Summary

- Clone `bunEnv` and delete `AGENTS` property in `beforeAll`
- Replace all `bunEnv` references with `testEnv` in test spawns
- Prevents parent process's `AGENTS` env var from leaking into tests

## Problem

The `claudecode-flag` test was using `bunEnv` directly, which includes
`...process.env`. When running in environments like Claude Code where
`AGENTS` may be set, this variable would leak into the test child
processes and potentially affect test behavior.

## Solution

Created a `testEnv` clone in `beforeAll` that explicitly deletes
`AGENTS`, ensuring consistent test behavior regardless of the parent
process's environment.

## Test plan

- [x] Test passes without `AGENTS` set
- [x] Test passes with `AGENTS=1` set in parent environment

0b7aed1d0d fix(test): remove quotes from string variables in test.each (#23244)
## Summary
Fixes #23206

When using `test.each` with object syntax and `$variable` interpolation,
string values were being quoted (e.g., `"apple"` instead of `apple`).
This didn't match the behavior of `%s` formatting or Jest's behavior.

## Changes
- Modified `formatLabel` in `src/bun.js/test/jest.zig` to check if the
value is a primitive string and use `toString()` instead of the
formatter with `quote_strings=true`
- Added regression test in `test/regression/issue/23206.test.ts`

## Example

**Before:**
```
test.each([
  { name: "apple" },
  { name: "banana" }
])("fruit #%# is $name", fruit => {
  // Test names were:
  // "fruit #0 is "apple""
  // "fruit #1 is "banana""
});
```

**After:**
```
test.each([
  { name: "apple" },
  { name: "banana" }
])("fruit #%# is $name", fruit => {
  // Test names are now:
  // "fruit #0 is apple"
  // "fruit #1 is banana"
});
```

## Test plan
- [x] Added regression test that verifies both `%s` and `$name` syntax
produce consistent output
- [x] Tested with `AGENT=0` - all tests pass
- [x] Verified other primitive types (numbers, booleans) still format
correctly
- [x] Verified complex objects still use proper formatting

This matches Jest's behavior after their fix:

d273f7fdde fix: zstd decompression with async-compressed data (#23314) (#23317)
### What does this PR do?

Fixes #23314 where `zlib.zstdCompress()` created data that caused an
out-of-memory error when decompressed with `Bun.zstdDecompressSync()`.

#### 1. `zlib.zstdCompress()` now sets `pledgedSrcSize`

The async convenience method now automatically sets the `pledgedSrcSize`
option to the input buffer size. This ensures the compressed frame
includes the content size in the header, making sync and async
compression produce identical output.

**Node.js compatibility**: `pledgedSrcSize` is a documented Node.js
option:
-
[`vendor/node/doc/api/zlib.md:754-758`](https://github.com/oven-sh/bun/blob/main/vendor/node/doc/api/zlib.md#L754-L758)
-
[`vendor/node/lib/zlib.js:893`](https://github.com/oven-sh/bun/blob/main/vendor/node/lib/zlib.js#L893)
-
[`vendor/node/src/node_zlib.cc:890-904`](https://github.com/oven-sh/bun/blob/main/vendor/node/src/node_zlib.cc#L890-L904)

#### 2. Added `bun.zstd.decompressAlloc()` - centralized safe
decompression

Created a new function in `src/deps/zstd.zig` that handles decompression
in one place with automatic safety features:

- **Handles unknown content sizes**: Automatically switches to streaming
decompression when the zstd frame doesn't include content size (e.g.,
from streams without `pledgedSrcSize`)
- **16MB safety limit**: For security, if the reported decompressed size
exceeds 16MB, streaming decompression is used instead of blindly
trusting the header
- **Fast path for small files**: Still uses efficient pre-allocation for
files < 16MB with known sizes

This centralized fix automatically protects:
- `Bun.zstdDecompressSync()` / `Bun.zstdDecompress()`
- `StandaloneModuleGraph` source map decompression
- Any other code using `bun.zstd` decompression

### How did you verify your code works?

**Before:**
```typescript
const input = "hello world";

// Async compression
const compressed = await new Promise((resolve, reject) => {
  zlib.zstdCompress(input, (err, result) => {
    if (err) reject(err);
    else resolve(result);
  });
});

// This would fail with "Out of memory"
const decompressed = Bun.zstdDecompressSync(compressed);
```
**Error**: `RangeError: Out of memory` (tried to allocate UINT64_MAX
bytes)

**After:**
```typescript
const input = "hello world";

// Async compression (now includes content size)
const compressed = await new Promise((resolve, reject) => {
  zlib.zstdCompress(input, (err, result) => {
    if (err) reject(err);
    else resolve(result);
  });
});

//  Works! Falls back to streaming decompression if needed
const decompressed = Bun.zstdDecompressSync(compressed);
console.log(decompressed.toString()); // "hello world"
```

**Tests:**
-  All existing tests pass
-  New regression tests for async/sync compression compatibility
(`test/regression/issue/23314/zstd-async-compress.test.ts`)
-  Test for large (>16MB) decompression using streaming
(`test/regression/issue/23314/zstd-large-decompression.test.ts`)
-  Test for various input sizes and types
(`test/regression/issue/23314/zstd-large-input.test.ts`)

**Security:**
The 16MB safety limit protects against malicious zstd frames that claim
huge decompressed sizes in the header, preventing potential OOM attacks.

5fca74a979 fix(sourcemap): escape tab characters in filenames for JSON (#23298)
## What does this PR do?

Fixes #22003 by escaping tab characters in filenames when generating
sourcemap JSON.

When a filename contained a tab character (e.g., `file\ttab.js`), the
sourcemap JSON would contain a **literal tab byte** instead of the
escaped `\t`, producing invalid JSON that caused `error:
InvalidSourceMap`.

The root cause was in `src/bun.js/bindings/highway_strings.cpp` where
the scalar fallback path had:
```cpp
if (char_ >= 127 || (char_ < 0x20 && char_ != 0x09) || ...)
```

This **exempted tab characters** (0x09) from being detected as needing
escape, while the SIMD path correctly detected them. The fix removes the
`&& char_ != 0x09` exemption so both paths consistently escape tabs.

## How did you verify your code works?

Added regression test in `test/regression/issue/22003.test.ts` that:
- Creates a file with a tab character in its filename
- Builds it with sourcemap generation
- Verifies the sourcemap is valid JSON
- Checks that the tab is escaped as `\t` (not a literal byte)

The test **fails on system bun** (produces invalid JSON with literal
tab):
```bash
USE_SYSTEM_BUN=1 bun test test/regression/issue/22003.test.ts
# error: JSON Parse error: Unterminated string
```

The test **passes with the fix** (tab properly escaped):
```bash
bun bd test test/regression/issue/22003.test.ts
# ✓ 1 pass
```

639d998055 fix: handle Darwin accept() bug with socklen=0 in uSockets (#21791)
## Summary

Fixes a macOS kernel (XNU) bug where `accept()` can return a valid
socket descriptor but with `addrlen=0`, indicating an already-dead
socket.

This occurs when an IPv4 connection to an IPv6 dual-stack listener is
immediately aborted (RST packet). The fix detects this condition on
Darwin and handles it intelligently - preserving buffered data when
present, discarding truly dead sockets when not.

## Background

This implements the equivalent of the bugfix from capnproto:
https://github.com/capnproto/capnproto/pull/2365

The issue manifests as:
1. IPv4 connection made to IPv6 dual-stack listener
2. Connection immediately aborted (sends RST packet)  
3. `accept()` returns valid socket descriptor but `addrlen=0`
4. Socket may have buffered data from `connectx()` or be truly dead

## Enhanced Data-Preserving Solution

Unlike simple "close immediately" approaches, this fix **prevents data
loss** from the `connectx()` edge case:

**Race Condition Scenario:**
1. Client uses `connectx()` to send data immediately during connection
2. Network abort (RST) occurs after data is buffered but before full
connection establishment
3. Darwin kernel returns `socklen=0` but socket has buffered data
4. **Our fix preserves this data instead of losing it**

**Logic:**
```c
if (addr->len == 0) {
    /* Check if there's any pending data before discarding the socket */
    char peek_buf[1];
    ssize_t has_data = recv(accepted_fd, peek_buf, 1, MSG_PEEK | MSG_DONTWAIT);
    
    if (has_data <= 0) {
        /* No data available, socket is truly dead - discard it */
        bsd_close_socket(accepted_fd);
        continue; /* Try to accept the next connection */
    }
    /* If has_data > 0, let the socket through - there's buffered data to read */
}
```

## XNU Kernel Source Analysis

After investigating the Darwin XNU kernel source code, I found this bug
affects **multiple system calls**, not just `accept()`. The bug is
rooted in the kernel's socket layer when protocol-specific functions
return NULL socket addresses.

### Affected System Calls

#### 1. accept() and accept_nocancel()  FIXED
**Location:**
[`/bsd/kern/uipc_syscalls.c:596-605`](https://github.com/apple/darwin-xnu/blob/main/bsd/kern/uipc_syscalls.c#L596-L605)

```c
(void) soacceptlock(so, &sa, 0);
socket_unlock(head, 1);
if (sa == NULL) {
    namelen = 0;  // ← BUG: Returns socklen=0
    if (uap->name) {
        goto gotnoname;
    }
    error = 0;
    goto releasefd;
}
```

#### 2. getsockname() ⚠️ ALSO AFFECTED
**Location:**
[`/bsd/kern/uipc_syscalls.c:2601-2603`](https://github.com/apple/darwin-xnu/blob/main/bsd/kern/uipc_syscalls.c#L2601-L2603)

```c
if (sa == 0) {
    len = 0;  // ← SAME BUG: Returns socklen=0
    goto gotnothing;
}
```

#### 3. getpeername() ⚠️ ALSO AFFECTED  
**Location:**
[`/bsd/kern/uipc_syscalls.c:2689-2691`](https://github.com/apple/darwin-xnu/blob/main/bsd/kern/uipc_syscalls.c#L2689-L2691)

```c
if (sa == 0) {
    len = 0;  // ← SAME BUG: Returns socklen=0
    goto gotnothing;
}
```

### System Calls NOT Affected

#### connect() and connectx()  SAFE
**Locations:** 
-
[`/bsd/kern/uipc_syscalls.c:686-744`](https://github.com/apple/darwin-xnu/blob/main/bsd/kern/uipc_syscalls.c#L686-L744)
(connect)
-
[`/bsd/kern/uipc_syscalls.c:747+`](https://github.com/apple/darwin-xnu/blob/main/bsd/kern/uipc_syscalls.c#L747)
(connectx)

**Why they're safe:** These functions read socket addresses from
userspace via `getsockaddr()` and pass them to the protocol layer. They
don't receive socket addresses from the network stack, so they can't
encounter the `socklen=0` condition.

### Root Cause

The bug occurs when protocol layer functions (`pru_accept`,
`pru_sockaddr`, `pru_peeraddr`) return NULL socket addresses during
IPv4→IPv6 dual-stack connection race conditions. The kernel returns
`socklen=0` instead of treating it as an error case.

**Key XNU source reference:**
[`/bsd/kern/uipc_socket.c:1544`](https://github.com/apple/darwin-xnu/blob/main/bsd/kern/uipc_socket.c#L1544)
```c
error = (*so->so_proto->pr_usrreqs->pru_accept)(so, nam);
```

**Socket state vs buffered data:** From
[`/bsd/kern/uipc_socket2.c:2227`](https://github.com/apple/darwin-xnu/blob/main/bsd/kern/uipc_socket2.c#L2227):
```c
// Even with SS_CANTRCVMORE set, data can be buffered in so->so_rcv.sb_cc
return so->so_rcv.sb_cc >= so->so_rcv.sb_lowat ||
       ((so->so_state & SS_CANTRCVMORE) && cfil_sock_data_pending(&so->so_rcv) == 0)
```

## Changes

- Added Darwin-specific check in `bsd_accept_socket()` in
`packages/bun-usockets/src/bsd.c:708-720`
- When `addr->len == 0` after successful `accept()`:
  1. Check for buffered data with `recv(MSG_PEEK | MSG_DONTWAIT)`
  2. If data exists, let socket through normally (prevents data loss)
  3. If no data, close socket and continue accepting
- Only applies to `__APPLE__` builds to avoid affecting other platforms

## Test plan

- [x] Debug build compiles successfully
- [x] Basic HTTP server operations work correctly (exercises accept
path)
- [x] Regression test covers IPv4→IPv6 dual-stack connection abort
scenarios
- [x] Test verifies server doesn't crash/hang when encountering
socklen=0 condition
- [x] Enhanced fix preserves buffered data from connectx() edge cases

The regression test
(`test/regression/issue/darwin-accept-socklen-zero.test.ts`) creates the
exact conditions that trigger this kernel bug:
1. IPv6 dual-stack server (`hostname: "::"`)  
2. IPv4 connections (`127.0.0.1`) with immediate abort (RST packets)
3. Concurrent connection attempts to maximize race condition probability
4. Verification that server remains stable and responsive

## Impact Assessment

### For Bun's uSockets Implementation
- **accept() path:**  FIXED with data loss prevention - This PR handles
the primary case affecting network servers
- **connect() path:**  NOT VULNERABLE - connect() doesn't receive
kernel sockaddrs
- **connectx() path:**  NOT VULNERABLE - connectx() doesn't receive
kernel sockaddrs
- **connectx() data:**  PRESERVED - Enhanced fix prevents losing
buffered data from immediate sends

### Additional Considerations
While `getsockname()` and `getpeername()` have the same kernel bug,
they're less critical for server stability since servers primarily use
`accept()` for incoming connections.

* logs the resolved one in --verbose (which can be helpful in debugging
to show it does know latest but couldn't use)
* makes bun outdated show in the table when the package isn't true

* includes a rudimentary "stability" check if a later version is in
blacked out time (but only up to 7 days as it goes back to latest with
min age)


For extended security we could also Last-Modified header of the tgz

1c363f0ad0 fix(parser): typeof minification regression (#23280)
### What does this PR do?
In Bun v1.2.22 a minification for `typeof x === "undefined"` → `typeof x
> "u"` was added. This introduced a regression causing `return (typeof x
!== "undefined", false)` to minify to invalid syntax when
`--minify-syntax` is enabled (this is also enabled for transpilation at
runtime).

This pr fixes the regression making sure `return (typeof x !==
"undefined", false);` minifies correctly to `return !1;`.

f0295ce0a5 Fix bunfig.toml parsing with UTF-8 BOM (#23276)
Fixes #23275

### What does this PR do?

This PR fixes a bug where `bunfig.toml` files starting with a UTF-8 BOM
(byte order mark, `U+FEFF` or bytes `0xEF 0xBB 0xBF`) would fail to
parse with an "Unexpected" error.

The fix uses Bun's existing `File.toSource()` function with
`convert_bom: true` option when loading config files. This properly
detects and strips the BOM before parsing, matching the behavior of
other file readers in Bun (like the JavaScript lexer which treats
`0xFEFF` as whitespace).

**Changes:**
- Modified `src/cli/Arguments.zig` to use `bun.sys.File.toSource()` with
BOM conversion instead of manually reading the file
- Simplified the config loading code by removing intermediate file
handle and buffer logic

### How did you verify your code works?

Added comprehensive regression tests in
`test/regression/issue/23275.test.ts` that verify:
1.  `bunfig.toml` with UTF-8 BOM parses correctly without errors
2.  `bunfig.toml` without BOM still works (regression test)
3.  `bunfig.toml` with BOM and actual config content parses the content
correctly

All three tests pass with the debug build:
```
 3 pass
 0 fail
 11 expect() calls
Ran 3 tests across 1 file. [6.41s]
```

The `bun outdated` command now displays catalog dependencies with their
workspace grouping even when run without the `--filter` or `-r` flags.

## What changed

- Added detection for catalog dependencies in the outdated packages list
- The workspace column is now shown when:
  - Using `--filter` or `-r` flags (existing behavior) 
  - OR when there are catalog dependencies to display (new behavior)
- When there are no catalog dependencies and no filtering, the workspace
column remains hidden as before

## Why

Previously, running `bun outdated` without any flags would not show
which workspaces were using catalog dependencies, making it unclear
where catalog entries were being used. This fix ensures catalog
dependencies are properly grouped and displayed with their workspace
information.

## Test

```bash
# Create a workspace project with catalog dependencies
mkdir test-catalog && cd test-catalog
cat > package.json << 'JSON'
{
  "name": "test-catalog",
  "workspaces": ["packages/*"],
  "catalog": {
    "react": "^17.0.0"
  }
}
JSON

mkdir -p packages/{app1,app2}
echo '{"name":"app1","dependencies":{"react":"catalog:"}}' > packages/app1/package.json
echo '{"name":"app2","dependencies":{"react":"catalog:"}}' > packages/app2/package.json

bun install
bun outdated  # Should now show catalog grouping without needing --filter
```

13a3c4de60 fix(install): fetch os/cpu metadata during yarn.lock migration (#23143)
## Summary

During `yarn.lock` migration, OS/CPU package metadata was not being
fetched from the npm registry when missing from `yarn.lock`. This caused
packages with platform-specific requirements to not be properly marked,
potentially leading to incorrect package installation behavior.

## Changes

Updated `fetchNecessaryPackageMetadataAfterYarnOrPnpmMigration` to
conditionally fetch OS/CPU metadata:

- **For yarn.lock migration**: Fetches OS/CPU metadata from npm registry
when not present in yarn.lock (`update_os_cpu = true`)
- **For pnpm-lock.yaml migration**: Skips OS/CPU fetching since
pnpm-lock.yaml already includes this data (`update_os_cpu = false`)

### Files Modified

- `src/install/lockfile.zig` - Added comptime `update_os_cpu` parameter
and conditional logic to fetch OS/CPU metadata
- `src/install/yarn.zig` - Pass `true` to enable OS/CPU fetching for
yarn migrations
- `src/install/pnpm.zig` - Pass `false` to skip OS/CPU fetching for pnpm
migrations (already parsed from lockfile)

## Why This Approach

- `yarn.lock` format often doesn't include OS/CPU constraints, requiring
us to fetch from npm registry
- `pnpm-lock.yaml` already parses OS/CPU during migration (lines 618-621
in pnpm.zig), making additional fetching redundant
- Using a comptime parameter allows the compiler to optimize away the
unused code path

## Testing

-  Debug build compiles successfully
- Tested that the function correctly updates `pkg_meta.os` and
`pkg_meta.arch` only when:
  - `update_os_cpu` is `true` (yarn migration)
  - Current values are `.all` (not already set)
  - Package metadata is available from npm registry

3c96c8a63d Add Claude Code hooks to prevent common development mistakes (#23241)
## Summary

Added Claude Code hooks to prevent common development mistakes when
working on the Bun codebase.

## Changes

- Created `.claude/hooks/pre-bash-zig-build.js` - A pre-bash hook that
validates commands
- Created `.claude/settings.json` - Hook configuration

## Prevented Mistakes

1. **Running `zig build obj` directly** → Redirects to use `bun bd`
2. **Using `bun test` in development** → Must use `bun bd test` (or set
`USE_SYSTEM_BUN=1`)
3. **Combining snapshot updates with test filters** → Prevents
`-u`/`--update-snapshots` with `-t`/`--test-name-pattern`
4. **Running `bun bd` with timeout** → Build needs time to complete
without timeout
5. **Running `bun bd test` from repo root** → Must specify a test file
path to avoid running all tests

## Test plan

- [x] Tested all validation rules with various command combinations
- [x] Verified USE_SYSTEM_BUN=1 bypass works
- [x] Verified file path detection works correctly

46e7a3b3c5 Implement birthtime support on Linux using statx syscall (#23209)
## Summary

- Adds birthtime (file creation time) support on Linux using the `statx`
syscall
- Stores birthtime in architecture-specific unused fields of the kernel
Stat struct (x86_64 and aarch64)
- Falls back to traditional `stat` on kernels < 4.11 that don't support
`statx`
- Includes comprehensive tests validating birthtime behavior

Fixes #6585

## Implementation Details

**src/sys.zig:**
- Added `StatxField` enum for field selection
- Implemented `statxImpl()`, `fstatx()`, `statx()`, and `lstatx()`
functions
- Stores birthtime in unused padding fields (architecture-specific for
x86_64 and aarch64)
- Graceful fallback to traditional stat if statx is not supported

**src/bun.js/node/node_fs.zig:**
- Updated `stat()`, `fstat()`, and `lstat()` to use statx functions on
Linux

**src/bun.js/node/Stat.zig:**
- Added `getBirthtime()` helper to extract birthtime from
architecture-specific storage

**test/js/node/fs/fs-birthtime-linux.test.ts:**
- Tests non-zero birthtime values
- Verifies birthtime immutability across file modifications
- Validates consistency across stat/lstat/fstat
- Tests BigInt stats with nanosecond precision
- Verifies birthtime ordering relative to other timestamps

## Test Plan

- [x] Run `bun bd test test/js/node/fs/fs-birthtime-linux.test.ts` - all
5 tests pass
- [x] Compare behavior with Node.js - identical behavior
- [x] Compare with system Bun - system Bun returns epoch, new
implementation returns real birthtime

6c8635da63 fix(install): isolated installs with transitive self dependencies (#23222)
### What does this PR do?
Packages with self dependencies at a different version were colliding
with the current version in the store node_modules. This pr nests them
in another node_modules

Example:
self-dep@1.0.2 has a dependency on self-dep@1.0.1.

self-dep@1.0.2 is placed here in:
`./node_modules/.bun/self-dep@1.0.2/node_modules/self-dep`

and it's self-dep dependency symlink is now placed in:

`./node_modules/.bun/self-dep@1.0.2/node_modules/self-dep/node_modules/self-dep`

fixes #22681

578a47ce4a Fix segmentation fault during building stack traces string (#22902)
### What does this PR do?

Bun sometimes crashes with a segmentation fault while generating stack
traces.

the following might be happening in `remapZigException`:

1. The first populateStackTrace (OnlyPosition) sets `frames_len` (e.g.,
frames_len = 5)
613aea1787/src/bun.js/bindings/bindings.cpp (L4793)
```
[frame1, frame2, frame3, frame4, frame5]
```

2. Frame filtering in remapZigException reduces `frames_len` (e.g.,
frames_len = 3)
613aea1787/src/bun.js/VirtualMachine.zig (L2686-L2704)
```
[frame1, frame4, frame5, (frame4, frame5)] 
// frame2 and frame3 are removed by filtering; frames_len is set to 3 here, but frame4 and frame5 remain in their original positions
```

3. The second populateStackTrace (OnlySourceLine) increases `frames_len`
(e.g., frames_len = 5)
613aea1787/src/bun.js/bindings/bindings.cpp (L4793)
```
[frame1, frame4, frame5, frame4, frame5]
```

When deinit is executed on these frames, the ref count is excessively
decremented (for frame4 and frame5), resulting in a UAF.

### How did you verify your code works?

WIP. I'm working on creating minimal reproduction code.

However, I've confirmed that `twenty-server` tests passes with this PR.

02d0586da5 Increase crash report stack trace buffer from 10 to 20 frames (#23225)
## Summary

Increase the stack trace buffer size in the crash handler from 10 to 20
frames to ensure more useful frames are included in crash reports sent
to bun.report.

## Motivation

Currently, we capture up to 10 stack frames when generating crash
reports. However, many of these frames get filtered out when
`StackLine.fromAddress()` returns `null` for invalid/empty frames. This
results in only a small number of frames (sometimes as few as 5)
actually being sent to the server.

## Changes

- Increased `addr_buf` array size from `[10]usize` to `[20]usize` in
`src/crash_handler.zig:307`

## Impact

By capturing more frames initially, we ensure that after filtering we
still have a meaningful number of frames in the crash report. This will
help with debugging crashes by providing more context about the call
stack.

The encoding function `encodeTraceString()` has no hardcoded limits and
will encode all available frames, so this change directly translates to
more frames being sent to bun.report.

2aa373ab63 Refactor: Split JSNodeHTTPServerSocket into separate files (#23203)
## Summary

Split `JSNodeHTTPServerSocket` and `JSNodeHTTPServerSocketPrototype`
from `NodeHTTP.cpp` into dedicated files, following the same pattern as
`JSDiffieHellman` in the crypto module.

## Changes

- **Created 4 new files:**
  - `JSNodeHTTPServerSocket.h` - Class declaration
  - `JSNodeHTTPServerSocket.cpp` - Class implementation and methods
  - `JSNodeHTTPServerSocketPrototype.h` - Prototype declaration  
- `JSNodeHTTPServerSocketPrototype.cpp` - Prototype methods and property
table

- **Moved from NodeHTTP.cpp:**
  - All custom getters/setters (onclose, ondrain, ondata, etc.)
  - All host functions (close, write, end)
  - Event handlers (onClose, onDrain, onData)
  - Helper functions and templates
  
- **Preserved:**
  - All extern C bindings for Zig interop
  - All existing functionality
  - Proper namespace and include structure

- **Merged changes from main:**
  - Added `upgraded` flag for websocket support (from #23150)
  - Updated `clearSocketData` to handle WebSocketData
  - Added `onSocketUpgraded` callback handler

## Impact

- Reduced `NodeHTTP.cpp` from ~1766 lines to 1010 lines (43% reduction)
- Better code organization and maintainability
- No functional changes

## Test plan

- [x] Build compiles successfully
- [x] `test/js/node/http/node-http.test.ts` passes (72/74 tests pass,
same as before)
- [x] `test/js/node/http/node-http-with-ws.test.ts` passes (websocket
upgrade test)

f14f3b03bb Add new bindings generator; port SSLConfig (#23169)
Add a new generator for JS → Zig bindings. The bulk of the conversion is
done in C++, after which the data is transformed into an FFI-safe
representation, passed to Zig, and then finally transformed into
idiomatic Zig types.

In its current form, the new bindings generator supports:

* Signed and unsigned integers
* Floats (plus a “finite” variant that disallows NaN and infinities)
* Strings
* ArrayBuffer (accepts ArrayBuffer, TypedArray, or DataView)
* Blob
* Optional types
* Nullable types (allows null, whereas Optional only allows undefined)
* Arrays
* User-defined string enumerations
* User-defined unions (fields can optionally be named to provide a
better experience in Zig)
* Null and undefined, for use in unions (can more efficiently represent
optional/nullable unions than wrapping a union in an optional)
* User-defined dictionaries (arbitrary key-value pairs; expects a JS
object and parses it into a struct)
* Default values for dictionary members
* Alternative names for dictionary members (e.g., to support both
`serverName` and `servername` without taking up twice the space)
* Descriptive error messages
* Automatic `fromJS` functions in Zig for dictionaries
* Automatic `deinit` functions for the generated Zig types

Although this bindings generator has many features not present in
`bindgen.ts`, it does not yet implement all of `bindgen.ts`'s
functionality, so for the time being, it has been named `bindgenv2`, and
its configuration is specified in `.bindv2.ts` files. Once all
`bindgen.ts`'s functionality has been incorporated, it will be renamed.

This PR ports `SSLConfig` to use the new bindings generator; see
`SSLConfig.bindv2.ts`.

a9b383bac5 fix(crypto): hkdf callback should pass null (not undefined) on success (#23216)
## Summary
- Fixed crypto.hkdf callback to pass `null` instead of `undefined` for
the error parameter on success
- Added regression test to verify the fix

## Details

Fixes #23211

Node.js convention requires crypto callbacks to receive `null` as the
error parameter on success, but Bun was passing `undefined`. This caused
compatibility issues with code that relies on strict null checks (e.g.,
[matter.js](fdbec2cf88/packages/general/src/crypto/NodeJsStyleCrypto.ts (L169))).

### Changes
- Updated `CryptoHkdf.cpp` to pass `jsNull()` instead of `jsUndefined()`
for the error parameter in the success callback
- Added regression test in `test/regression/issue/23211.test.ts`

## Test plan
- [x] Added regression test that verifies callback receives `null` on
success
- [x] Test passes with the fix
- [x] Ran existing crypto tests (no failures)

c8cb7713fc Fix Windows crash in process.title when console title is empty (#23184)
## Summary

Fixes a segmentation fault on Windows 11 when accessing `process.title`
in certain scenarios (e.g., when fetching system information or making
Discord webhook requests).

## Root Cause

The crash occurred in libuv's `uv_get_process_title()` at `util.c:413`
in the `strlen()` call. The issue is that `uv__get_process_title()`
could return success (0) but leave `process_title` as NULL in edge cases
where:

1. `GetConsoleTitleW()` returns an empty string
2. `uv__convert_utf16_to_utf8()` succeeds but doesn't allocate memory
for the empty string
3. The subsequent `assert(process_title)` doesn't catch this in release
builds
4. `strlen(process_title)` crashes with a null pointer dereference

## Changes

Added defensive checks in `BunProcess.cpp`:
1. Initialize the title buffer to an empty string before calling
`uv_get_process_title()`
2. Check if the buffer is empty after the call returns
3. Fall back to "bun" if the title is empty or the call fails

## Testing

Added regression test in `test/regression/issue/23183.test.ts` that
verifies:
- `process.title` doesn't crash when accessed
- Returns a valid string (either the console title or "bun")

Fixes #23183

79e0aa9bcf bun:test performance regression fix (#23199)
### What does this PR do?

Fixes #23120

bun:test changes introduced an added 16-100ms sleep between test files.
For a test suite with many fast-running test files, this caused
significant impact. Elysia's test suite was running 2x slower (1.8s →
3.9s).

# WebKit Update Summary (September 2025)

## Overview
This document summarizes the major changes in WebKit/JavaScriptCore from
the September 2025 update. The update includes approximately 254
JSC-related commits with significant improvements to performance,
stability, and developer experience.

## Critical Bug Fixes

### Memory Safety
- **operationMaterializeObjectInOSR fix** (5c7aadfa0a96): Fixed
uninitialized Butterfly storage during OSR exits with sunk Array
allocations. This prevents potential crashes when arrays with holes are
materialized during OSR exit.
- **FTL materialization fixes** (a72d19840714, ed1e6fe03899): Added
missing internal object type handling in FTL materialization, improving
stability during optimization bailouts.

### Promise and Async Improvements
- **JSPromiseReaction object** (a1cb5e087a46, later reverted in
b0566a4db201): Initially introduced to improve promise reaction handling
but was reverted due to compatibility issues with Bun's modifications.
- **Async stack traces enhancements**:
  - Added support for `Promise.any` in async stack traces (d9a997b3edaa)
- Added empty JSValue checking for async stack trace safety
(9d26223d4bcb)
- Promise.all support was added and later reverted due to performance
concerns

## Performance Optimizations

### JIT Compiler Improvements
- **B3 Immutable Loads** (570a3530f949, 62300f8db3d9): Added
immutability annotations and CSE optimizations for loads that can look
for targets in dominators
- **BBQ JIT enhancements**:
  - Fixed callee-save register handling (c7ae05719045)
  - Simplified F32 copysign operations (e0651af57025)
- **DFG optimizations**:
- Fixed RegExp constant folding with materialized NewRegExp nodes
(7b53a04a5afa)
- Improved RegExp object node handling in strength reduction
(eeb65e05095b)

### WebAssembly Improvements
- **WASM SIMD Support**:
- Added v128 support for IPInt call and tail-call instructions
(73f0c9d430cb)
- Implemented v128 support in local.get, local.set, global.get,
global.set (67d7bf15139a)
  - Added x86_64 SIMD integer arithmetic and float instructions
- **WASM Memory Management**:
- Introduced WasmInstanceAnchor for better instance lifecycle management
(f9f1ed183bf7)
- Attached AbstractHeap to wasm memory access for better optimization
(f183c6f7def4)
  - Added signal handling for null checks in wasm (bf18b5b709f3)
- **WASM Debugging**: Added LLDB debugging infrastructure for
WebAssembly (e03c10225cc8)

## API and Language Features

### Iterator Helpers
- Merged `Iterator.prototype.sliding` into `Iterator.prototype.windows`
(1d49e823702d)
- Optimized iterator next method calls using CachedCall (5ee92514060c)

### Math Extensions
- Improved performance of `Math.sumPrecise` implementation
(602294057337)

### Error Handling
- Enhanced error messages for for-of loops without Symbol.iterator
(0051bbf2491f)

## Infrastructure Changes

### Character Type Refactoring
- **LChar to Latin1Character rename** (63b97b511366, 1424f0687876):
Major refactoring replacing the `LChar` type with `Latin1Character`
throughout the codebase for better clarity
- Additional fixes for Latin1Character usage (711eab3243f0,
50bf8e6fd4ca, 88e29ab76aec)

### Build System
- Fixed builds with GCC 15.x (e33b18bc59d6)
- Added gitattributes for JSC test files (82c4cc796da6)
- Improved test runner with comprehensive verbose logging (7ef95c177a42)
- Added memory-limited annotations for tests using excessive memory
(b991cd17d612)

### Testing Infrastructure
- Improved handling of missing test executables (db1e3bbb3be2)
- Added support for non-customized ICU 74.2 in intl tests (c922a28b6642)
- Fixed various test configuration issues and timeouts

## Bun-Specific Modifications

### Preserved Customizations
- Maintained `BUN_JSC_ADDITIONS` for Bun-specific features
- Kept async context support for AsyncLocalStorage
- Preserved V8 heap snapshot compatibility layer
- Maintained custom inspector extensions

### Conflicts Resolved
- Successfully merged upstream changes while preserving Bun's event loop
integration
- Resolved conflicts in promise handling while maintaining Bun's async
behavior
- Fixed re-declaration issues with `isAsyncFrame` for async stack traces

## Breaking Changes and Reverts

### Reverted Features
1. **JSPromiseReaction object**: Reverted due to conflicts with Bun's
promise handling
2. **Promise.all async stack trace support**: Reverted due to ~4%
performance regression in JetStream3/doxbee-async benchmark
3. **Array.prototype.flat C++ implementation**: Reverted (reason not
specified in commit)

## Security Improvements
- Type safety improvements with uncheckedDowncast for Wasm::Callee
(48425afd643d)
- Added bounds checking and validation for Wasm array operations
(b5148db1c4c1)
- Improved memory safety with proper initialization of materialized
objects

## Platform Support
- macOS: Continued support for x64/arm64
- Linux: Maintained glibc/musl compatibility
- Windows: Preserved x64 support
- Fixed platform-specific alignment issues for x86_64 (94a60eb123c5)

## Notable Debugging Enhancements
- LLDB infrastructure for WebAssembly debugging
- Improved verbose command logging in test runners
- Enhanced stack trace capabilities for async functions
- Better error reporting for missing Symbol.iterator

## Performance Metrics
- Several memory optimizations for test execution
- JIT memory reservation size adjustments for debug builds
- Optimized iterator operations with cached calls
- Improved Math.sumPrecise performance

## Future Considerations
- The JSPromiseReaction implementation may need revisiting with adjusted
architecture
- Async stack trace support for Promise.all requires performance
optimization
- Continued work on WASM SIMD support for additional operations

## Migration Notes for Bun Team
1. **LChar usage**: All references to `LChar` have been replaced with
`Latin1Character`
2. **Promise handling**: The reverted JSPromiseReaction changes indicate
potential architectural conflicts that may need addressing
3. **Test configuration**: New memory-limited annotations should be used
for memory-intensive tests
4. **Build flags**: Ensure USE_BUN_JSC_ADDITIONS and USE_BUN_EVENT_LOOP
remain enabled

9e6ba35ff7 Allow multiple inline snapshots in one call if they are the same (#23117)
Multiple inline snapshots from one call should be avoided because they
will cause problems if one changes but not the other, but this allows
them if they both have the same value.

### What does this PR do?

bad:

```ts
function oops(a) {
  expect(a).toMatchInlineSnapshot();
}
test("whoops", () => {
  oops(1);
  oops(2);
});
```

```
2 |   expect(a).toMatchInlineSnapshot();
                                      ^
error: Failed to update inline snapshot: Multiple inline snapshots on the same line must all have the same value:
Expected: 1
Received: 2
    at /Users/pfg/Dev/Node/bun/repro.ts:2:35
```

acceptable:

```ts
function ok(a) {
  expect(a).toMatchInlineSnapshot(`1`);
}
test("whokay", () => {
  ok(1);
  ok(1);
});
```

```

eac82e2184 Fix memory.deinit; handle more types (#23032)
* Fix `memory.deinit`; the previous PR erroneously added non-comptime
code in a comptime expression, which would result in a compile error
when trying to deinit an optional
* Handle arrays (distinct from slices)
* Handle error unions
* Disallow untagged unions, as this is probably an error; usually a
manual deinit impl is needed if untagged unions are involved
* Make switch exhaustive so we know we're not missing other types

c5005a37d7 Fix --tolerate-republish flag in bun publish (continues PR #22107) (#22381)
## Summary
This PR continues the work from #22107 to fix the `--tolerate-republish`
flag implementation in `bun publish`.

### Changes:
- **Pre-check version existence**: Before attempting to publish with
`--tolerate-republish`, check if the version already exists on the
registry
- **Improved version checking**: Use GET request to package endpoint
instead of HEAD, then parse JSON response to check if specific version
exists
- **Correct output stream**: Output warning to stderr instead of stdout
for consistency with test expectations
- **Better error handling**: Update test to accept both 403 and 409 HTTP
error codes for duplicate publish attempts

### Test fixes:
The tests were failing because:
1. The mock registry returns 409 Conflict (not 403) for duplicate
packages
2. The warning message wasn't appearing in stderr as expected
3. The version check was using HEAD request which doesn't reliably
return version info

## Test plan
- [x] Fixed failing tests for `--tolerate-republish` functionality
- [x] Tests now properly handle both 403 and 409 error responses
- [x] Warning messages appear correctly in stderr

a89e61fcaa ssg 3 (#22138)
### What does this PR do?

Fixes a crash related to the dev server overwriting the uws user context
pointer when setting abort callback.

Adds support for `return new Response(<jsx />, { ... })` and `return
Response.render(...)` and `return Response.redirect(...)`:
- Created a `SSRResponse` class to handle this (see
`JSBakeResponse.{h,cpp}`)
- `SSRResponse` is designed to "fake" being a React component 
- This is done in JSBakeResponse::create inside of
src/bun.js/bindings/JSBakeResponse.cpp
- And `src/js/builtins/BakeSSRResponse.ts` defines a `wrapComponent`
function which wraps
the passed in component (when doing `new Response(<jsx />, ...)`). It
does
    this to throw an error (in redirect()/render() case) or return the
    component.
- Created a `BakeAdditionsToGlobal` struct which contains some
properties
    needed for this
- Added some of the properties we need to fake to BunBuiltinNames.h
(e.g.
    `$$typeof`), the rationale behind this is that we couldn't use
`structure->addPropertyTransition` because JSBakeResponse is not a final
    JSObject.
- When bake and server-side, bundler rewrites `Response ->
Bun.SSRResponse` (see `src/ast/P.zig` and `src/ast/visitExpr.zig`)
- Created a new WebCore body variant (`Render: struct { path: []const u8
}`)
  - Created when `return Response.render(...)`
  - When handled, it re-invokes dev server to render the new path

Enables server-side sourcemaps for the dev server:
- New source providers for server-side:
(`DevServerSourceProvider.{h,cpp}`)
- IncrementalGraph and SourceMapStore are updated to support this

There are numerous other stuff:
- allow `app` configuration from Bun.serve(...)
- fix errors stopping dev server
- fix use after free related to in
RequestContext.finishRunningErrorHandler
- Request.cookies
- Make `"use client";` components work
- Fix some bugs using `require(...)` in dev server
- Fix catch-all routes not working in the dev server
- Updates `findSourceMappingURL(...)` to use `std.mem.lastIndexOf(...)`
because
  the sourcemap that should be used is the last one anyway

2b7fc18092 fix(lint): resolve no-unused-expressions errors (#23127)
## Summary

Fixes all oxlint `no-unused-expressions` violations across the codebase
by:
- Adding an oxlint override to disable the rule for
`src/js/builtins/**`, where special syntax markers like `$getter`,
`$constructor`, etc. are intentionally used as standalone expressions
- Converting short-circuit expressions (`condition && fn()`) to proper
if statements for improved code clarity
- Wrapping intentional property access side effects (e.g.,
`this.stdio;`, `err.stack;`) with the `void` operator

e3a1ae09f3 docs: add zstd compression documentation for v1.2.14 (#23095)
## Summary
- Documents zstd compression features introduced in Bun v1.2.14
- Adds missing API documentation for zstd utilities

## Changes
- Updated `docs/api/fetch.md` to include zstd in Accept-Encoding
examples and note automatic decompression support
- Added `Bun.zstdCompress()/zstdCompressSync()` and
`Bun.zstdDecompress()/zstdDecompressSync()` documentation to
`docs/api/utils.md`
- Documented compression levels (1-22) with concise usage examples

## Note
HTTP/2 features (`maxSendHeaderBlockLength` and `setNextStreamID`) were
not added per request to avoid updating nodejs-apis.md.

25e156c95b fix(pnpm migration): correctly resolve link: dependencies on the root package (#23111)
### What does this PR do?
Two things:
- we weren't adding the root package to the `pkg_map`.
- `link:` dependency paths in `"snapshots"` weren't being joined with
the top level dir.
### How did you verify your code works?
Manually and added a test.

b5a56c183b fix(test): update error message assertion for git clone failure (#23119)
## Summary
- Updated test assertion to match new error message format for git clone
failures

## Details
The error message format changed from:
```
error: "git clone" for "uglify" failed
```

To:
```
error: InstallFailed cloning repository for uglify
```

This appears to be due to changes in how 404s work on the bun.sh domain.

621066d0c4 Fix crash in toContainAnyKeys and toContainKeys with non-object values (#22977)
## Summary
- Fixed segmentation fault when calling `toContainAnyKeys`,
`toContainKeys`, and `toContainAllKeys` on non-object values (null,
undefined, numbers, strings, etc.)
- Added proper validation to check if value is an object before calling
`hasOwnPropertyValue` or `keys()`
- Added comprehensive test coverage for edge cases

## Problem
The matchers were crashing with a segmentation fault when called with
non-object values because:

1. `toContainAnyKeys` and `toContainKeys` were calling
`hasOwnPropertyValue` without checking if the value is an object first
2. `toContainAllKeys` was calling `keys()` without checking if the value
is an object first
3. The `hasOwnPropertyValue` function documentation explicitly states:
"If the object is not an object, it will crash. **You must check if the
object is an object before calling this function.**"

## Solution
- Added `value.isObject()` check in `toContainAnyKeys` before attempting
to check for properties
- Fixed `toContainKeys` by replacing the `toBoolean()` check with
`isObject()` check
- Fixed `toContainAllKeys` by adding proper object validation before
calling `keys()`
- For non-objects with empty expected arrays, the matchers return true
(matching jest-extended behavior)

## Test plan
- [x] Added comprehensive test coverage in
`test/js/bun/test/expect.test.js`
- [x] Tests cover: null, undefined, numbers, strings, booleans, symbols,
BigInt, arrays, functions
- [x] All existing jest-extended tests continue to pass
- [x] Debug build compiles and all tests pass

```go
// Returns true if the current less-than token is considered to be an arrow
// function under TypeScript's rules for files containing JSX syntax
func (p *parser) isTSArrowFnJSX() (isTSArrowFn bool) {
	oldLexer := p.lexer
	p.lexer.Next()

	// Look ahead to see if this should be an arrow function instead
	if p.lexer.Token == js_lexer.TConst {
		p.lexer.Next()
	}
	if p.lexer.Token == js_lexer.TIdentifier {
		p.lexer.Next()
		if p.lexer.Token == js_lexer.TComma || p.lexer.Token == js_lexer.TEquals {
			isTSArrowFn = true
		} else if p.lexer.Token == js_lexer.TExtends {
			p.lexer.Next()
			isTSArrowFn = p.lexer.Token != js_lexer.TEquals && p.lexer.Token != js_lexer.TGreaterThan && p.lexer.Token != js_lexer.TSlash
		}
	}

	// Restore the lexer
	p.lexer = oldLexer
	return

    roles TEXT[]
);
```

```js
const item = { id: 1, name: "test", role: sql.array(['a', 'b'], "TEXT") };
await sql`
  UPDATE user
  SET ${sql(item)}
  WHERE id = 1
`;

5a12175cb0 Fix V8StackTraceIterator to handle frames without parentheses (#23034)
## Summary
- Fixes V8StackTraceIterator terminating early when encountering stack
frames without parentheses (e.g., "at unknown")
- Ensures complete stack traces are shown by `Bun.inspect()` even after
`error.stack` property is accessed
- Addresses the root cause that PR #23022 was working around

## Problem
When the V8StackTraceIterator encountered a stack frame line without
parentheses (like `at unknown`), it would:
1. Set `offset = stack.length()` 
2. Return `false`, terminating the entire iteration
3. Only parse frames before the "unknown" frame

This caused `Bun.inspect()` to show incomplete stack traces after the
`error.stack` property was accessed, as documented in issue discussions
around PR #23022.

## Solution
Changed the parser to continue iterating through subsequent frames
instead of terminating. Frames without parentheses are now treated as
having a source URL but no function name or location info.

## Test plan
- [x] Added regression test
`test/regression/issue/23022-stack-trace-iterator.test.ts`
- [x] Verified existing stack trace tests still pass
- [x] Manually tested with Node.js stream errors that trigger this code
path

### Before fix:
```
error: Socket is closed
 code: "ERR_SOCKET_CLOSED"

      at node:net:1322:32
```

### After fix:
```
error: Socket is closed
 code: "ERR_SOCKET_CLOSED"

      at unknown:1:1
      at _write (node:net:1322:32)
      at writeOrBuffer (internal:streams/writable:381:18)
      at internal:streams/writable:334:16
      at testStackTrace (/workspace/bun/test.js:8:10)
      ...
```

73feb108d9 Handle optionals in bun.memory.deinit (#23027)
Currently, if you try to deinit an optional, `bun.memory.deinit` will
silently do nothing, even if the optional's payload is a struct with a
`deinit` method.

This commit makes sure the payload is deinitialized.

Previously `redis.subscribe` did not automatically connect, which was in
contrast to other Redis functions. This PR changes the necessary
`PUB/SUB` things so that `.subscribe` automatically connects.

8102e80f88 fix(build): Promise.all() async module dependencies (#22704)
### What does this PR do?
Currently bundling and running projects with cyclic async module
dependencies will hang due to module promises never resolving. This PR
unblocks these projects by outputting `await Promise.all` with these
dependencies.

Before (will hang with bun, or error with unsettled top level await with
node):
```js
var __esm = (fn, res) => () => (fn && (res = fn((fn = 0))), res);

var init_mod3 = __esm(async () => {
  await init_mod1();
});

var init_mod2 = __esm(async () => {
  await init_mod1();
});

var init_mod1 = __esm(async () => {
  await init_mod2();
  await init_mod3();
});

await init_mod1();
```

After:
```js
var __esm = (fn, res) => () => (fn && (res = fn((fn = 0))), res);
var __promiseAll = Promise.all.bind(Promise);

var init_mod3 = __esm(async () => {
  await init_mod1();
});

var init_mod2 = __esm(async () => {
  await init_mod1();
});

var init_mod1 = __esm(async () => {
  await __promiseAll([init_mod2(), init_mod3()]);
});

await init_mod1();
```

Reduce the size of `bun.webcore.Blob` from 120 bytes to 96. Also make it
ref-counted: in-progress work on improving the bindings generator
depends on this, as it means C++ can pass a pointer to the `Blob` to Zig
without risking it being destroyed if the GC collects the associated
`JSBlob`.

Add a version of `ArrayList` that takes a generic `Allocator` type
parameter. This matches the interface of smart pointers like
`bun.ptr.Owned` and `bun.ptr.Shared`.

This type behaves like a managed `ArrayList` but has no overhead if
`Allocator` is a zero-sized type, like `bun.DefaultAllocator`.

266fca2e5c Add ExternalShared and RawRefCount (#23013)
Add `bun.ptr.ExternalShared`, a shared pointer whose reference count is
managed externally; e.g., by extern functions. This can be used to work
with `RefCounted` C++ objects in Zig. For example:

```cpp
// C++:
struct MyType : RefCounted<MyType> { ... };
extern "C" void MyType__ref(MyType* self) { self->ref(); }
extern "C" void MyType__ref(MyType* self) { self->deref(); }
```

```zig
// Zig:
const MyType = opaque {
    extern fn MyType__ref(self: *MyType) void;
    extern fn MyType__deref(self: *MyType) void;

    pub const Ref = bun.ptr.ExternalShared(MyType);

    // This enables `ExternalShared` to work.
    pub const external_shared_descriptor = struct {
        pub const ref = MyType__ref;
        pub const deref = MyType__deref;
    };
};

// Now `MyType.Ref` behaves just like `Ref<MyType>` in C++:
var some_ref: MyType.Ref = someFunctionReturningMyTypeRef();
const ptr: *MyType = some_ref.get(); // gets the inner pointer
var some_other_ref = some_ref.clone(); // increments the ref count
some_ref.deinit(); // decrements the ref count
// decrements the ref count again; if no other refs exist, the object
// is destroyed
some_other_ref.deinit();
```

This commit also adds `RawRefCount`, a simple wrapper around an integer
reference count that can be used to implement the interface required by
`ExternalShared`. Generally, for reference-counted Zig types,
`bun.ptr.Shared` is preferred, but occasionally it is useful to have an
“intrusive” reference-counted type where the ref count is stored in the
type itself. For this purpose, `ExternalShared` + `RawRefCount` is more
flexible and less error-prone than the deprecated `bun.ptr.RefCounted`
type.

f45900d7e6 fix(fetch): print request body for application/x-www-form-urlencoded in curl logs (#22849)
### What does this PR do?

fixes an issue where fetch requests with `Content-Type:
application/x-www-form-urlencoded` would not include the request body in
curl logs when `BUN_CONFIG_VERBOSE_FETCH=curl` is enabled

previously, only JSON and text-based content types were recognized as
safe-to-print in the curl formatter. This change updates the allow-list
to also handle `application/x-www-form-urlencoded`, ensuring bodies for
common form submissions are shown in logs

### How did you verify your code works?

- added `Content-Type: application/x-www-form-urlencoded` to a fetch
request and confirmed that `BUN_CONFIG_VERBOSE_FETCH=curl` now outputs a
`--data-raw` section with the encoded body
- verified the fix against the reproduction script provided in issue
#12042
 - created and ran a regression test
- checked that existing content types (JSON, text, etc.) continue to
print correctly

17b503b389 Redis PUB/SUB 2.0 (#22568)
### What does this PR do?

**This PR is created because [the previous PR I
opened](https://github.com/oven-sh/bun/pull/21728) had some concerning
issues.** Thanks @Jarred-Sumner for the help.

The goal of this PR is to introduce PUB/SUB functionality to the
built-in Redis client. Based on the fact that the current Redis API does
not appear to have compatibility with `io-redis` or `redis-node`, I've
decided to do away with existing APIs and API compatibility with these
existing libraries.

I have decided to base my implementation on the [`redis-node` pub/sub
API](https://github.com/redis/node-redis/blob/master/docs/pub-sub.md).

#### Random Things That Happened

- [x] Refactored the build scripts so that `valgrind` can be disabled.
- [x] Added a `numeric` namespace in `harness.ts` with useful
mathematical libraries.
- [x] Added a mechanism in `cppbind.ts` to disable static assertions
(specifically to allow `check_slow` even when returning a `JSValue`).
Implemented via `// NOLINT[NEXTLINE]?\(.*\)` macros.
- [x] Fixed inconsistencies in error handling of `JSMap`.

### How did you verify your code works?

I've written a set of unit tests to hopefully catch the major use-cases
of this feature. They all appear to pass.


#### Future Improvements

I would have a lot more confidence in our Redis implementation if we
tested it with a test suite running over a network which emulates a high
network failure rate. There are large amounts of edge cases that are
worthwhile to grab, but I think we can roll that out in a future PR.

### Future Tasks

- [ ] Tests over flaky network
- [ ] Use the custom private members over `_<member>`.

5457d76bcb Fix double-free in createArgv function (#22978)
## Summary
- Fixed a double-free bug in the `createArgv` function in
`node_process.zig`

## Details
The `createArgv` function had two `defer allocator.free(args)`
statements:
- One on line 164 
- Another on line 192 (now removed)

This would cause the same memory to be freed twice when the function
returned, leading to undefined behavior.

Fixes #22975

## Test plan
The existing process.argv tests should continue to pass with this fix.

d3061de1bf feat(windows): implement authenticode stripping for --compile (#22960)
## Summary

Implements authenticode signature stripping for Windows PE files when
using `bun build --compile`, ensuring that generated executables can be
properly signed with external tools after Bun embeds its data section.

## What Changed

### Core Implementation
- **Authenticode stripping**: Removes digital signatures from PE files
before adding the .bun section
- **Safe memory access**: Replaced all `@alignCast` operations with safe
unaligned access helpers to prevent crashes
- **Hardened PE parsing**: Added comprehensive bounds checking and
validation throughout
- **PE checksum recalculation**: Properly updates checksums after
modifications

### Key Features
- Always strips authenticode signatures when using `--compile` for
Windows (uses `.strip_always` mode)
- Validates PE file structure according to PE/COFF specification
- Handles overlapping memory regions safely during certificate removal
- Clears `IMAGE_DLLCHARACTERISTICS_FORCE_INTEGRITY` flag when stripping
signatures
- Ensures no unexpected overlay data remains after stripping

### Bug Fixes
- Fixed memory corruption bug using `copyBackwards` for overlapping
regions
- Fixed checksum calculation skipping 6 bytes instead of 4
- Added integer overflow protection in payload size calculations
- Fixed double alignment bug in `size_of_image` calculation

## Technical Details

The implementation follows the Windows PE/COFF specification and
includes:

- `StripMode` enum to control when signatures are stripped
(none/strip_if_signed/strip_always)
- Safe unaligned memory access helpers (`viewAtConst`, `viewAtMut`)
- Proper alignment helpers with overflow protection (`alignUpU32`,
`alignUpUsize`)
- Comprehensive error types for all failure cases

## Testing

- Passes all existing PE tests in
`test/regression/issue/pe-codesigning-integrity.test.ts`
- Compiles successfully with `bun run zig:check-windows`
- Properly integrated with StandaloneModuleGraph for Windows compilation

## Impact

This ensures Windows users can:
1. Use `bun build --compile` to create standalone executables
2. Sign the resulting executables with their own certificates
3. Distribute properly signed Windows binaries

Fixes issues where previously signed executables would have invalid
signatures after Bun added its embedded data.

58782ceef2 Fix bun_dependency_versions.h regenerating on every CMake run (#22985)
## Summary
- Fixes unnecessary regeneration of `bun_dependency_versions.h` on every
CMake run
- Only writes the header file when content actually changes

## Test plan
Tested locally by running CMake configuration multiple times:
1. First run generates the file (shows "Updated dependency versions
header")
2. Subsequent runs skip writing (shows "Dependency versions header
unchanged")
3. File modification timestamp remains unchanged when content is the

4dfd87a302 Fix aborting fetch() calls while the socket is connecting. Fix a thread-safety issue involving redirects and AbortSignal. (#22842)
### What does this PR do?

When we added "happy eyeballs" support to fetch(), it meant that
`onOpen` would not be called potentially for awhile. If the AbortSignal
is aborted between `connect()` and the socket becoming
readable/writable, then we would delay closing the connection until the
connection opens. Fixing that fixes #18536.

Separately, the `isHTTPS()` function used in abort and in request body
streams was not thread safe. This caused a crash when many redirects
happen simultaneously while either AbortSignal or request body messages
are in-flight.
This PR fixes https://github.com/oven-sh/bun/issues/14137

be15f6c80c feat(test): add --randomize flag to run tests in random order (#22945)
## Summary

This PR adds a `--randomize` flag to `bun test` that shuffles test
execution order. This helps developers catch test interdependencies and
identify flaky tests that may depend on execution order.

## Changes

-  Added `--randomize` CLI flag to test command
- 🔀 Implemented test shuffling using `bun.fastRandom()` as PRNG seed
- 🧪 Added comprehensive tests to verify randomization behavior
- 📝 Tests are shuffled at the scheduling phase, properly handling
describe blocks and hooks

## Usage

```bash
# Run tests in random order
bun test --randomize

# Works with other test flags
bun test --randomize --bail
bun test mytest.test.ts --randomize
```

## Implementation Details

The randomization happens in `Order.zig`'s `generateOrderDescribe`
function, which shuffles the `current.entries.items` array when the
randomize flag is set. This ensures:

- All tests still run (just in different order)
- Hooks (beforeAll, afterAll, beforeEach, afterEach) maintain proper
relationships
- Describe blocks and their children are shuffled independently
- Each run uses a different random seed for varied execution orders

## Test Coverage

Added tests in `test/cli/test/test-randomize.test.ts` that verify:
- Tests run in random order with the flag
- All tests execute (none are skipped)
- Without the flag, tests run in consistent order
- Randomization works with describe blocks

## Example Output

```bash
# Without --randomize (consistent order)
$ bun test mytest.js
Running test 1
Running test 2
Running test 3
Running test 4
Running test 5

# With --randomize (different order each run)
$ bun test mytest.js --randomize
Running test 3
Running test 5
Running test 1
Running test 4
Running test 2

$ bun test mytest.js --randomize
Running test 2
Running test 4
Running test 5
Running test 1
Running test 3
```

## Summary
- Fixes double slashes appearing in error stack traces when `root_path`
ends with a trailing slash
- Followup to #22469 which added dimmed cwd prefixes to error messages

## Changes
- Use `strings.withoutTrailingSlash()` to strip any trailing separator
from `root_path` before adding the path separator
- This prevents paths like `/workspace//file.js` from appearing in error
messages

fee28ca66f Fix dns.resolve callback parameters to match Node.js behavior (#22814)
## Summary
- Fixed `dns.resolve()` callback to pass 2 parameters instead of 3,
matching Node.js
- Fixed `dns.promises.resolve()` to return array of strings for A/AAAA
records instead of objects
- Added comprehensive regression tests

## What was wrong?

The `dns.resolve()` callback was incorrectly passing 3 parameters
`(error, hostname, results)` instead of Node.js's 2 parameters `(error,
results)`. Additionally, `dns.promises.resolve()` was returning objects
with `{address, family}` instead of plain string arrays for A/AAAA
records.

## How this fixes it

1. Removed the extra `hostname` parameter from the callback in
`dns.resolve()` for A/AAAA records
2. Changed promise version to use `promisifyResolveX(false)` instead of
`promisifyLookup()` to return string arrays
3. Applied same fixes to the `Resolver` class methods

## Test plan
- Added regression test `test/regression/issue/22712.test.ts` with 6
test cases
- All tests pass with the fix
- Verified existing DNS tests still pass

Fixes #22712

## Summary
- Clarifies help text for `--reporter` and `--reporter-outfile` flags
- Improves error messages when invalid reporter formats are specified
- Makes distinction between test reporters and coverage reporters
clearer

## Changes
1. Updated help text in `Arguments.zig` to better explain:
   - What formats are currently available (only 'junit' for --reporter)
   - Default behavior (console output for tests)
   - Requirements (--reporter-outfile needed with --reporter=junit)
   
2. Improved error messages to list available options when invalid
formats are used

3. Updated CLI completions to match the new help text

## Test plan
- [x] Built and tested with `bun bd`
- [x] Verified help text displays correctly: `./build/debug/bun-debug
test --help`
- [x] Tested error message for invalid reporter:
`./build/debug/bun-debug test --reporter=json`
- [x] Tested error message for missing outfile: `./build/debug/bun-debug

57b93f6ea3 Fix panic when macros return collections with 3+ arrays/objects (#22827)
## Summary

Fixes #22656, #11730, and #7116

Fixes a panic that occurred when macros returned collections containing
three or more arrays or objects.

## Problem

The issue was caused by hash table resizing during recursive processing.
When `this.run()` was called recursively to process nested
arrays/objects, it could add more entries to the `visited` map,
triggering a resize. This would invalidate the `_entry.value_ptr`
pointer obtained from `getOrPut`, leading to memory corruption and
crashes.

## Solution

The fix ensures we handle hash table resizing safely:

1. Use `getOrPut` to reserve an entry and store a placeholder
2. Process all children (which may trigger hash table resizing)
3. Create the final expression with all data
4. Use `put` to update the entry (safe even after resizing)

This approach is applied consistently to both arrays and objects.

## Verification

All three issues have been tested and verified as fixed:

###  #22656 - "Panic when returning collections with three or more
arrays or objects"
- **Before**: `panic(main thread): switch on corrupt value`
- **After**: Works correctly

###  #11730 - "Constructing deep objects in macros causes segfaults"
- **Before**: `Segmentation fault at address 0x8` with deep nested
structures
- **After**: Handles deep nesting without crashes

###  #7116 - "[macro] crash with large complex array"
- **Before**: Crashes with objects containing 50+ properties (hash table
stress)
- **After**: Processes large complex arrays successfully

## Test Plan

Added comprehensive regression tests that cover:
- Collections with 3+ arrays
- Collections with 3+ objects
- Deeply nested structures (5+ levels)
- Objects with many properties (50+) to stress hash table operations
- Mixed collections of arrays and objects

All tests pass with the fix applied.

e58a4a7282 feat: add concurrent-test-glob option to bunfig.toml for selective concurrent test execution (#22898)
## Summary

Adds a new `concurrentTestGlob` configuration option to bunfig.toml that
allows test files matching a glob pattern to automatically run with
concurrent test execution enabled. This provides granular control over
which tests run concurrently without modifying test files or using the
global `--concurrent` flag.

## Problem

Currently, enabling concurrent test execution in Bun requires either:
1. Using the `--concurrent` flag (affects ALL tests)
2. Manually adding `test.concurrent()` to individual test functions
(requires modifying test files)

This creates challenges for:
- Large codebases wanting to gradually migrate to concurrent testing
- Projects with mixed test types (unit tests that need isolation vs
integration tests that can run in parallel)
- CI/CD pipelines that want to optimize test execution without code
changes

## Solution

This PR introduces a `concurrentTestGlob` option in bunfig.toml that
automatically enables concurrent execution for test files matching a
specified glob pattern:

```toml
[test]
concurrentTestGlob = "**/concurrent-*.test.ts"
```

### Key Features
-  Non-breaking: Completely opt-in via configuration
-  Flexible: Use glob patterns to target specific test files or
directories
-  Override-friendly: `--concurrent` flag still forces all tests to run
concurrently
-  Zero code changes: No need to modify existing test files

## Implementation Details

### Code Changes
1. Added `concurrent_test_glob` field to `TestOptions` struct
(`src/cli.zig`)
2. Added parsing for `concurrentTestGlob` from bunfig.toml
(`src/bunfig.zig`)
3. Added `concurrent_test_glob` field to `TestRunner`
(`src/bun.js/test/jest.zig`)
4. Implemented `shouldFileRunConcurrently()` method that checks file
paths against the glob pattern
5. Updated test execution logic to apply concurrent mode based on glob
matching (`src/bun.js/test/ScopeFunctions.zig`)

### How It Works
- When a test file is loaded, its path is checked against the configured
glob pattern
- If it matches, all tests in that file run concurrently (as if
`--concurrent` was passed)
- Files not matching the pattern run sequentially as normal
- The `--concurrent` CLI flag overrides this behavior when specified

## Usage Examples

### Basic Usage
```toml
# bunfig.toml
[test]
concurrentTestGlob = "**/integration/*.test.ts"
```

### Multiple Patterns
```toml
[test]
concurrentTestGlob = [
  "**/integration/*.test.ts",
  "**/e2e/*.test.ts", 
  "**/concurrent-*.test.ts"
]
```

### Migration Strategy
Teams can gradually migrate to concurrent testing:
1. Start with integration tests: `"**/integration/*.test.ts"`
2. Add stable unit tests: `"**/fast-*.test.ts"`
3. Eventually migrate most tests except those requiring isolation

## Testing

Added comprehensive test coverage in
`test/cli/test/concurrent-test-glob.test.ts`:
-  Tests matching glob patterns run concurrently (verified via
execution order logging)
-  Tests not matching patterns run sequentially (verified via shared
state and execution order)
-  `--concurrent` flag properly overrides the glob setting
- Tests use file system logging to deterministically verify concurrent
vs sequential execution

## Documentation

Complete documentation added:
- `docs/runtime/bunfig.md` - Configuration reference
- `docs/test/configuration.md` - Test configuration details
- `docs/test/examples/concurrent-test-glob.md` - Comprehensive example
with migration guide

## Performance Considerations

- Glob matching happens once per test file during loading
- Uses Bun's existing `glob.match()` implementation
- Minimal overhead: simple string pattern matching
- Future optimization: Could cache match results per file path

## Breaking Changes

None. This is a fully backward-compatible, opt-in feature.

## Checklist

- [x] Implementation complete and building
- [x] Tests passing
- [x] Documentation updated
- [x] No breaking changes
- [x] Follows existing code patterns

## Related Issues

This addresses common requests for more granular control over concurrent
test execution, particularly for large codebases migrating from other
test runners.

1a23797e82 feat: add test.serial() API for forcing serial test execution (#22899)
## Summary

Adds a new `test.serial()` API that forces tests to run serially even
when the `--concurrent` flag is passed. This is the opposite of
`test.concurrent()` which forces parallel execution.

## Motivation

Some tests genuinely need to run serially even in CI environments with
`--concurrent`:
- Database migration tests that must run in order
- Tests that modify shared global state
- Tests that use fixed ports or file system resources
- Tests that depend on timing or resource constraints

## Implementation

Changed `self_concurrent` from `bool` to `?bool`:
- `null` = default behavior (inherit from parent or use default)
- `true` = force concurrent execution
- `false` = force serial execution

## API Surface

```javascript
// Force serial execution
test.serial("database migration", async () => {
  // This runs serially even with --concurrent flag
});

// All modifiers work
test.serial.skip("skip this serial test", () => {});
test.serial.todo("implement this serial test");
test.serial.only("only run this serial test", () => {});
test.serial.each([[1], [2]])("serial test %i", (n) => {});
test.serial.if(condition)("conditional serial", () => {});

// Works with describe too
describe.serial("serial test suite", () => {
  test("test 1", () => {}); // runs serially
  test("test 2", () => {}); // runs serially
});

// Explicit test-level settings override describe-level
describe.concurrent("concurrent suite", () => {
  test.serial("this runs serially", () => {}); // serial wins
  test("this runs concurrently", () => {});
});
```

## Test Coverage

Comprehensive tests added including:
- Basic `test.serial()` functionality
- All modifiers (skip, todo, only, each, if)
- `describe.serial()` blocks
- Mixing serial and concurrent tests in same describe block
- Nested describe blocks with conflicting settings
- Explicit overrides (test.serial in describe.concurrent and vice versa)

All 36 tests pass 

## Example

```javascript
// Without this PR - these tests might run in parallel with --concurrent
test("migrate database schema v1", async () => { await migrateV1(); });
test("migrate database schema v2", async () => { await migrateV2(); });
test("migrate database schema v3", async () => { await migrateV3(); });

16435f3561 Make sure bun can be installed on Alpine Linux (musl) on arm64 hardware (#22892)
### What does this PR do?
This PRs adjusts the "arch" string for Linux-musl variant to make sure
it can be installed on ARM64 platforms using `npm`. Without this fix,
installing bun on Alpine Linux on arm64 fails because the native binary
cannot be found.

#### Why it fails
Bun attempts to find/download the native binaries during the postinstall
phase (see
[install.ts](https://github.com/oven-sh/bun/blob/bun-v1.1.42/packages/bun-release/src/npm/install.ts)).
The platform matching logic lives in
[platform.ts](https://github.com/oven-sh/bun/blob/bun-v1.1.42/packages/bun-release/src/platform.ts).
Note how the "musl" variant is marked [as
"aarch64"](https://github.com/oven-sh/bun/blob/bun-v1.1.42/packages/bun-release/src/platform.ts#L63-L69),
while the regular "glibc" variant is marked [as
"arm64"](https://github.com/oven-sh/bun/blob/bun-v1.1.42/packages/bun-release/src/platform.ts#L44-L49).
On Alpine Linux distributions (or when using "node-alpine" docker image)
we're supposed to be using the "musl" binary. However, since bun marks
it as "aarch64" while the matching logic relies on `process.arch`, it
never gets matched. Node.js uses "arm64", _not_ "aarch64" (see
["process.arch"
docs](https://nodejs.org/docs/latest-v22.x/api/process.html#processarch)).
In short - a mismatch between the expected arch ("aarch64") and the
actual reported arch ("arm64") prevents bun from finding the right
binary when installing with npm/pnpm.

### How did you verify your code works?
Verified by running the installer on Alpine Linux on arm64.

a8ccdb02e9 fix(benchmark): postgres benchmark was not performing any queries under deno and node (#22926)
### What does this PR do?
Fixes the postgres benchmark so that it actually benchmarks query
performance on node and deno.

Before this PR, the `sql` function was just creating a tagged template
function, which involved connecting to the database. So basically bun
was doing queries, but node and deno were just connecting to the
postgres database over and over.

You can see from the first example in the docs that you're supposed to
call the default export in order to get back a function to use with
template literals: https://www.npmjs.com/package/postgres

e555702653 Fix infinite recursion when error.stack is a circular reference (#22863)
## Summary

This PR fixes infinite recursion and stack overflow crashes when error
objects have circular references in their properties, particularly when
`error.stack = error`.

### The Problem
When an error object's stack property references itself or creates a
circular reference chain, Bun would enter infinite recursion and crash.
Common patterns that triggered this:
```javascript
const error = new Error();
error.stack = error;  // Crash!
console.log(error);

// Or circular cause chains:
error1.cause = error2;
error2.cause = error1;  // Crash!
```

### The Solution
Added proper circular reference detection at three levels:

1. **C++ bindings layer** (`bindings.cpp`): Skip processing if `stack`
property equals the error object itself
2. **VirtualMachine layer** (`VirtualMachine.zig`): Track visited errors
when printing error instances and their causes
3. **ConsoleObject layer** (`ConsoleObject.zig`): Properly coordinate
visited map between formatters

Circular references are now safely detected and printed as `[Circular]`
instead of causing crashes.

## Test plan

Added comprehensive tests in
`test/regression/issue/circular-error-stack.test.ts`:
-  `error.stack = error` circular reference
-  Nested circular references via error properties  
-  Circular cause chains (`error1.cause = error2; error2.cause =
error1`)

All tests pass:
```
bun test circular-error-stack.test.ts
✓ error with circular stack reference should not cause infinite recursion
✓ error with nested circular references should not cause infinite recursion  
✓ error with circular reference in cause chain
```

Manual testing:
```javascript
// Before: Stack overflow crash
// After: Prints error normally
const error = new Error("Test");
error.stack = error;
console.log(error);  // error: Test
```

285143dc66 fix(install): change semver core numbers to u64 (#22889)
### What does this PR do?
Sometimes packages will use very large numbers exceeding max u32 for
major/minor/patch (usually patch). This pr changes each core number in
bun to u64.

Because we serialize package information to disk for the binary lockfile
and package manifests, this pr bumps the version of each. We don't need
to change anything other than the version for serialized package
manifests because they will invalidate and save the new version. For old
binary lockfiles, this pr adds logic for migrating to the new version.
Even if there are no changes, migrating will always save the new
lockfile. Unfortunately means there will be a one time invisible diff
for binary lockfile users, but this is better than installs failing to
work.

### How did you verify your code works?

33fdc2112f feat: add --cpu and --os flags to bun install for filtering optional dependencies (#22850)
## Summary

Implements `--cpu` and `--os` flags for `bun install` to filter optional
dependencies based on target architecture and operating system. This
allows developers to control which platform-specific optional
dependencies are installed.

## What Changed

### Core Implementation
- Added `--cpu` and `--os` flags to `bun install` command that accept
multiple values
- Multiple values combine with bitwise OR (e.g., `--cpu x64 --cpu arm64`
matches packages for either architecture)
- Updated `isDisabled` methods throughout the codebase to accept custom
CPU/OS targets
- Removed deprecated `isMatch` methods in favor of `isMatchWithTarget`
for consistency

### Files Modified
- `src/install/npm.zig` - Removed `isMatch` methods, standardized on
`isMatchWithTarget`
- `src/install/PackageManager/CommandLineArguments.zig` - Parse and
validate multiple flag values
- `src/install/PackageManager/PackageManagerOptions.zig` - Pass CPU/OS
options through
- `src/install/lockfile/Package.zig` & `Package/Meta.zig` - Updated
`isDisabled` signatures
- `src/install/lockfile/Tree.zig` & `lockfile.zig` - Updated call sites

## Usage Examples

```bash
# Install only x64 dependencies
bun install --cpu x64

# Install dependencies for both x64 and arm64
bun install --cpu x64 --cpu arm64

# Install Linux-specific dependencies
bun install --os linux

# Install for multiple platforms
bun install --cpu x64 --cpu arm64 --os linux --os darwin
```

## Test Plan

 All 10 tests pass in `test/cli/install/bun-install-cpu-os.test.ts`:
- CPU architecture filtering
- OS filtering
- Combined CPU and OS filtering
- Multiple CPU architectures support
- Multiple operating systems support
- Multiple CPU and OS combinations
- Error handling for invalid values
- Negated CPU/OS support (`!arm64`, `!linux`)

aa4e4f18a4 vscode extention - don't require start " " in test name pattern (#22844)
### What does this PR do?

#22534 made `--test-name-pattern` more logical and not start with empty
` ` (space), so fixing the built regex to make it work still for old and
new bun

The other main issue that that pr did was make start events for filtered
out names which means it appears to rerun them all even when in reality
it doesn't as they are skipped

Also in theory with concurrent test, if there's an error after another
started it would be assigned to the wrong test because we don't get test
id's in the error event, so its just assumed its from the last started
one which with parallel means it isn't correct.

71a8900013 refactor: move jsxSideEffects from tsconfig to jsx build config (#22665)
## Summary
- Moved `jsxSideEffects` (now `sideEffects`) from tsconfig.json compiler
options to the jsx object in the build API
- Updated all jsx bundler tests to use the new jsx.sideEffects
configuration
- Added jsx configuration parsing to JSBundler.zig

## Changes
- Removed jsxSideEffects parsing from `src/resolver/tsconfig_json.zig`
- Added jsx configuration parsing to `src/bun.js/api/JSBundler.zig`
Config.fromJS
- Fixed TransformOptions to properly pass jsx config to the transpiler
in `src/bundler/bundle_v2.zig`
- Updated TypeScript definitions to include jsx field in BuildConfigBase
- Modified test framework to support jsx configuration in API mode
- Updated all jsx tests to use `sideEffects` in the jsx config instead
of `side_effects` in tsconfig

## Test plan
All 27 jsx bundler tests are passing with the new configuration
structure.

7c0574eeb4 feat: Implement process.report.getReport() on Windows (#22816)
## Summary

This PR implements the Node.js-compatible `process.report.getReport()`
API on Windows, which was previously returning a "Not implemented"
message.

fixes https://github.com/rollup/rollup/issues/6119

fixes #11992

## Changes

###  Implementation
- Full Windows support for `process.report.getReport()`
- Uses libuv APIs (`uv_cpu_info`, `uv_interface_addresses`) for
cross-platform consistency
- Refactored to share common code between Windows and POSIX platforms
(~150 lines reduced)
- Returns comprehensive diagnostic information matching Node.js
structure

### 📊 Key Features Implemented

**System Information:**
-  CPU information: All processors with model, speed, and usage times
-  Network interfaces: Complete with MAC addresses, IPs, and netmasks  
-  Memory statistics: RSS, page faults, system memory info using
Windows APIs
-  Process information: PID, CWD, command line arguments, Windows
version detection

**JavaScript Runtime:**
-  JavaScript heap information with all V8-compatible heap spaces
-  JavaScript stack traces with proper formatting
-  Environment variables
-  Loaded DLLs in sharedObjects array

### 🧪 Testing
- Added comprehensive test suite with 10 tests covering all report
sections
- Tests validate structure, data types, and field presence
- All tests passing on Windows

```bash
bun test test/js/node/process/process.test.js -t "process.report"
# 10 pass, 0 fail
```

## Compatibility

Matches Node.js report structure exactly on Windows:
- Correctly omits `userLimits` and `uvthreadResourceUsage` (not present
in Node.js on Windows)
- Includes Windows-specific `libUrl` field in release object
- Returns same top-level keys as Node.js

## Example Output

```javascript
const report = process.report.getReport();
console.log(report.header.cpus.length); // 24
console.log(report.header.osVersion);   // "Windows 11 Pro"
console.log(report.sharedObjects.filter(so => so.includes('.dll')).length); // 36+
```

## Test Plan

```bash
# Run the new tests
bun bd test test/js/node/process/process.test.js -t "process.report"

# Verify output structure matches Node.js
node -e "console.log(Object.keys(process.report.getReport()).sort())"
bun bd -e "console.log(Object.keys(process.report.getReport()).sort())"
```

Fixes #5585, Fixes #9548, Might fix 5996

# New features:

## Concurrent tests

Concurrent tests allow running multiple async tests at the same time.

```ts
// concurrent.test.ts
test.concurrent("this takes a while 1", async () => {
  await Bun.sleep(1000);
});
test.concurrent("this takes a while 2", async () => {
  await Bun.sleep(1000);
});
test.concurrent("this takes a while 3", async () => {
  await Bun.sleep(1000);
});
```

Without `.concurrent`, this test file takes 3 seconds to run because
each one has to wait for the one before it to finish before it can
start.

With `.concurrent`, this file takes 1 second because all three sleeps
can run at once.

```
$> bun-after test concurrent
concurrent.test.js:
✓ this takes a while 1 [1005.36ms]
✓ this takes a while 2 [1012.51ms]
✓ this takes a while 3 [1013.15ms]

 3 pass
 0 fail
Ran 3 tests across 1 file. [1081.00ms]
```

To run all tests as concurrent, pass the `--concurrent` flag when
running tests.

Limitations:

- concurrent tests cannot attribute `expect()` call counts to the test,
meaning `expect.assertions()` does not function
- concurrent tests cannot use `toMatchSnapshot`. `toMatchInlineSnapshot`
is still supported.
- `beforeAll`/`afterAll` will never be executed concurrently.
`beforeEach`/`afterEach` will.

## Chaining

Chaining multiple describe/test qualifiers is now allowed. Previously,
it would fail.

```ts
// chaining-test-qualifiers.test.ts
test.failing.each([1, 2, 3])("each %i", async i => {
  throw new Error(i);
});
```

```
$> bun-after test chaining-test-qualifiers
a.test.js:
✓ each 1
✓ each 2
✓ each 3
```

# Breaking changes:

## Describe ordering

Previously, describe callbacks were called immediately. Now, they are
deferred until the outer callback has finished running. The previous
order matched Jest. The new order is similar to Vitest, but does not
match exactly.

```ts
// describe-ordering.test.ts
describe("outer", () => {
  console.log("outer before");
  describe("inner", () => {
    console.log("inner");
  });
  console.log("outer after");
});
```

Before, this would print

```
$> bun-before test describe-ordering
outer before
inner
outer after
```

Now, this will print

```
$> bun-after test describe-ordering
outer before
outer after
inner
```

## Test ordering

Describes are no longer always called before tests. They are now in
order.

```ts
// test-ordering.test.ts
test("one", () => {});
describe("scope", () => {
  test("two", () => {});
});
test("three", () => {});
```

Before, this would print

```
$> bun-before test test-ordering
✓ scope > two
✓ one
✓ three
```

Now, this will print

```
$> bun-after test test-ordering
✓ one
✓ scope > two
✓ three
```

## Preload hooks

Previously, beforeAll in a preload ran before the first file and
afterAll ran after the last file. Now, beforeAll will run at the start
of each file and afterAll will run at the end of each file. This
behaviour matches Jest and Vitest.

```ts
// preload.ts
beforeAll(() => console.log("preload: beforeAll"));
afterAll(() => console.log("preload: afterAll"));
```

```ts
// preload-ordering-1.test.ts
test("demonstration file 1", () => {});
```

```ts
// preload-ordering-2.test.ts
test("demonstration file 2", () => {});
```

```
$> bun-before test --preload=./preload preload-ordering
preload-ordering-1.test.ts:
preload: beforeAll
✓ demonstration file 1

preload-ordering-2.test.ts:
✓ demonstration file 2
preload: afterAll
```

```
$> bun-after test --preload=./preload preload-ordering
preload-ordering-1.test.ts:
preload: beforeAll
✓ demonstration file 1
preload: afterAll

preload-ordering-2.test.ts:
preload: beforeAll
✓ demonstration file 2
preload: afterAll
```

## Describe failures

Current behaviour is that when an error is thrown inside a describe
callback, none of the tests declared there will run. Now, describes
declared inside will also not run. The new behaviour matches the
behaviour of Jest and Vitest.

```ts
// describe-failures.test.ts
describe("erroring describe", () => {
  test("this test does not run because its describe failed", () => {
    expect(true).toBe(true);
  });
  describe("inner describe", () => {
    console.log("does the inner describe callback get called?");
    test("does the inner test run?", () => {
      expect(true).toBe(true);
    });
  });
  throw new Error("uh oh!");
});
```

Before, the inner describe callback would be called and the inner test
would run, although the outer test would not:

```
$> bun-before test describe-failures
describe-failures.test.ts:
does the inner describe callback get called?

# Unhandled error between tests
-------------------------------
11 |   throw new Error("uh oh!");
             ^
error: uh oh!
-------------------------------

✓ erroring describe > inner describe > does the inner test run?

 1 pass
 0 fail
 1 error
 1 expect() calls
Ran 1 test across 1 file.
Exited with code [1]
```

Now, the inner describe callback is not called at all.

```
$> bun-after test describe-failures
describe-failures.test.ts:

# Unhandled error between tests
-------------------------------
11 |   throw new Error("uh oh!");
             ^
error: uh oh!
-------------------------------


 0 pass
 0 fail
 1 error
Ran 0 tests across 1 file.
Exited with code [1]
```

## Hook failures

Previously, a beforeAll failure would skip subsequent beforeAll()s, the
test, and the afterAll. Now, a beforeAll failure skips any subsequent
beforeAll()s and the test, but not the afterAll.

```js
beforeAll(() => {
  throw new Error("before all: uh oh!");
});
test("my test", () => {
  console.log("my test");
});
afterAll(() => console.log("after all"));
```

```
$> bun-before test hook-failures
Error: before all: uh oh!

$> bun-after test hook-failures
Error: before all: uh oh!
after all
```

Previously, an async beforeEach failure would still allow the test to
run. Now, an async beforeEach failure will prevent the test from running

```js
beforeEach(() => {
  await 0;
  throw "uh oh!";
});
it("the test", async () => {
  console.log("does the test run?");
});
```

```
$> bun-before test async-beforeeach-failure
does the test run?
error: uh oh!
uh oh!
✗ the test

$> bun-after test async-beforeeach-failure
error: uh oh!
uh oh!
✗ the test
```

## Hook timeouts

Hooks will now time out, and can have their timeout configured in an
options parameter

```js
beforeAll(async () => {
  await Bun.sleep(1000);
}, 500);
test("my test", () => {
  console.log("ran my test");
});
```

```
$> bun-before test hook-timeouts
ran my test
Ran 1 test across 1 file. [1011.00ms]

$> bun-after test hook-timeouts
✗ my test [501.15ms]
  ^ a beforeEach/afterEach hook timed out for this test.
```

## Hook execution order

beforeAll will now execute before the tests in the scope, rather than
immediately when it is called.

```ts
describe("d1", () => {
  beforeAll(() => {
    console.log("<d1>");
  });
  test("test", () => {
    console.log("  test");
  });
  afterAll(() => {
    console.log("</d1>");
  });
});
describe("d2", () => {
  beforeAll(() => {
    console.log("<d2>");
  });
  test("test", () => {
    console.log("  test");
  });
  afterAll(() => {
    console.log("</d2>");
  });
});
```

```
$> bun-before test ./beforeall-ordering.test.ts
<d1>
<d2>
  test
</d1>
  test
</d2>

$> bun-after test ./beforeall-ordering.test.ts
<d1>
  test
</d1>
<d2>
  test
</d2>
```

## test inside test

test() inside test() now errors rather than silently failing. Support
for this may be added in the future.

```ts
test("outer", () => {
    console.log("outer");
    test("inner", () => {
        console.log("inner");
    });
});
```

```
$> bun-before test
outer
✓ outer [0.06ms]

 1 pass
 0 fail
Ran 1 test across 1 file. [8.00ms]

$> bun-after test
outer
1 | test("outer", () => {
2 |     console.log("outer");
3 |     test("inner", () => {
        ^
error: Cannot call test() inside a test. Call it inside describe() instead.
✗ outer [0.71ms]

 0 pass
 1 fail
```

## afterAll inside test

afterAll inside a test is no longer allowed

```ts
test("test 1", () => {
  afterAll(() => console.log("afterAll"));
  console.log("test 1");
});
test("test 2", () => {
  console.log("test 2");
});
```

```
$> bun-before
test 1
✓ test 1 [0.05ms]
test 2
✓ test 2
afterAll

$> bun-after
error: Cannot call afterAll() inside a test. Call it inside describe() instead.
✗ test 1 [1.00ms]
test 2
✓ test 2 [0.20ms]
```

# Only inside only

Previously, an outer 'describe.only' would run all tests inside it even
if there was an inner 'test.only'. Now, only the innermost only tests
are executed.

```ts
describe.only("outer", () => {
    test("one", () => console.log("should not run"));
    test.only("two", () => console.log("should run"));
});
```

```
$> bun-before test
should not run
should run

$> bun-after test
should run
```

With no inner only, the outer only will still run all tests:

```ts
describe.only("outer", () => {
    test("test 1", () => console.log("test 1 runs"));
    test("test 2", () => console.log("test 2 runs"));
});
```

# Potential follow-up work

- [ ] for concurrent tests, display headers before console.log messages
saying which test it is for
  - this will need async context or similar
- refActiveExecutionEntry should also be able to know the current test
even in test.concurrent
- [ ] `test("rerun me", () => { console.log("run one time!"); });`
`--rerun-each=3` <- this runs the first and third time but not the
second time. fix.
- [ ] should to cache the JSValue created from
DoneCallback.callAsFunction
- [ ] implement retry and rerun params for tests.
- [ ] Remove finalizer on ScopeFunctions.zig by storing the data in 3
jsvalues passed in bind rather than using a custom class. We should also
migrate off of the ClassGenerator for ScopeFunctions
- [ ] support concurrent limit, how many concurrent tests are allowed to
run at a time. ie `--concurrent-limit=25`
- [ ] flag to run tests in random order
- [ ] `test.failing` should have its own style in the same way
`test.todo` passing marks as 'todo' insetead of 'passing'. right now
it's `✓` which is confusing.
- [ ] remove all instances of bun.jsc.Jest.Jest.current
  - [ ] test options should be in BunTestRoot
- [ ] we will need one global still, stored in the globalobject/vm/?.
but it should not be a Jest instance.
- [ ] consider allowing test() inside test(), as well as afterEach and
afterAll. could even allow describe() too. to do this we would switch
from indices to pointers and they would be in a linked list. they would
be allocated in memorypools for perf/locality. some special
consideration is needed for making sure repeated tests lose their
temporary items. this could also improve memory usage soomewhat.
- [ ] consider using a jsc Bound Function rather than CallbackWithArgs.
bound functions allow adding arguments and they are only one value for
GC instead of many. and this removes our unnecessary three copies.
- [ ] eliminate Strong.Safe. we should be using a C++ class instead.
- [ ] consider modifying the junit reporter to print the whole describe
tree at the end instead of trying to output as test results come in. and
move it into its own file.
- [ ] expect_call_count/expect_assertions is confusing. rename to
`expect_calls`, `assert_expect_calls`. or something.
- [ ] Should make line_no be an enum with a none option and a function
to get if line nombers are enabled
- [ ] looks like we don't need to use file_id anymore (remove
`bun.jsc.Jest.Jest.runner.?.getOrPutFile(file_path).file_id;`, store the
file path directly)
- [ ] 'dot' test reporter like vitest?
- [ ] `test.failing.if(false)` errors because it can't replace mode
'failing' with mode 'skip'. this should probably be allowed instead.
- [ ] trigger timeout termination exception for `while(true) {}`
- [ ] clean up unused callbacks. as soon as we advance to the next
execution group, we can fully clean out the previous one. sometimes
within an execution sequence we can do the same.
  - clean by swapping held values with undefined
- [ ] structure cache for performance for donecallback/scopefunctions
- [ ] consider migrating CallbackWithArgs to be a bound function. the
length of the bound function can exclude the specified args.
- [ ] setting both result and maybe_skip is not ideal, maybe there
should be a function to do both at once?
- [ ] try using a linked list rather than arraylist for describe/test
children, see how it affects performance
- [ ] consider a memory pool for describescope/executionentry. test if
it improves performance.
- [ ] consider making RefDataValue methods return the reason for failure
rather than ?value. that way we can improve error messages. the reason
could be a string or it could be a defined error set
- [ ] instead of 'description orelse (unnamed)', let's have description
default to 'unnamed' and not free it if it === the global that defines
that
- [ ] Add a phase before ordering results that inherits properties to
the parents. (eg inherit only from the child and inherit has_callback
from the child. and has_callback can be on describe/test individually
rather than on base). then we won't have that happening in an init()
function (terrible!)
- [ ] this test was incidentally passing because resolves.pass() wasn't
waiting for promise
  ```
  test("fetching with Request object - issue #1527", async () => {
    const server = createServer((req, res) => {
      res.end();
    }).listen(0);
    try {
      await once(server, "listening");

      const body = JSON.stringify({ foo: "bar" });
const request = new Request(`http://localhost:${server.address().port}`,
{
        method: "POST",
        body,
      });

      expect(fetch(request)).resolves.pass();
    } finally {
      server.closeAllConnections();
    }
  });
  ```
- [ ] the error "expect.assertions() is not supported in the describe
phase, in concurrent tests, between tests, or after test execution has
completed" is not very good. we should be able to identify which of
those it is and print the right error for the context
- [ ] consider: instead of storing weak pointers to BunTest, we can
instead give the instance an id and check that it is correct when
getting the current bun test instance from the ref
- [ ] auto_killer: add three layers of auto_killer:
  - preload (includes file & test)
  - file (includes test)
  - test
- that way at the end of the test, we kill the test processes. at the
end of the file, we kill the file processes. at the end of all, we kill
anything remaining.

AsyncLocalStorage

- store active_id & refdatavalue. active_id is a replacement for the
above weak pointers thing. refdatavalue is for determining which test it
is. this probably fits in 2×u64
- use for auto_killer so timeouts can kill even in concurrent tests

f8aed4826b Migrate all Docker usage to unified docker-compose infrastructure (#22740)
## Summary

This PR migrates all Docker container usage in tests from individual
`docker run` commands to a centralized Docker Compose setup. This makes
tests run **10x faster**, eliminates port conflicts, and provides a much
better developer experience.

## What is Docker Compose?

Docker Compose is a tool for defining and running multi-container Docker
applications. Instead of each test file managing its own containers with
complex `docker run` commands, we define all services once in a YAML
file and Docker Compose handles the orchestration.

## The Problem (Before)

```javascript
// Each test file managed its own container
const container = await Bun.spawn({
  cmd: ["docker", "run", "-d", "-p", "0:5432", "postgres:15"],
  // ... complex setup
});
```

**Issues:**
- Each test started its own container (30+ seconds for PostgreSQL tests)
- Containers were killed after each test (wasteful!)
- Random port conflicts between tests
- No coordination between test suites
- Docker configuration scattered across dozens of test files

## The Solution (After)

```javascript
// All tests share managed containers
const pg = await dockerCompose.ensure("postgres_plain");
// Container starts only if needed, returns connection info
```

**Benefits:**
- Containers start once and stay running (3 seconds for PostgreSQL tests
- **10x faster!**)
- Automatic port management (no conflicts)
- All services defined in one place
- Lazy loading (services only start when needed)
- Same setup locally and in CI

## What Changed

### New Infrastructure
- `test/docker/docker-compose.yml` - Defines all test services
- `test/docker/index.ts` - TypeScript API for managing services  
- `test/docker/README.md` - Comprehensive documentation
- Configuration files and init scripts for services

### Services Migrated

| Service | Status | Tests |
|---------|--------|--------|
| PostgreSQL (plain, TLS, auth) |  | All passing |
| MySQL (plain, native_password, TLS) |  | All passing |
| S3/MinIO |  | 276 passing |
| Redis/Valkey |  | 25/26 passing* |
| Autobahn WebSocket |  | 517 available |

*One Redis test was already broken before migration (reconnection test
times out)

### Key Features

- **Dynamic Ports**: Docker assigns available ports automatically (no
conflicts!)
- **Unix Sockets**: Proxy support for PostgreSQL and Redis Unix domain
sockets
- **Persistent Data**: Volumes for services that need data to survive
restarts
- **Health Checks**: Proper readiness detection for all services
- **Backward Compatible**: Fallback to old Docker method if needed

## Performance Improvements

| Test Suite | Before | After | Improvement |
|------------|--------|-------|-------------|
| PostgreSQL | ~30s | ~3s | **10x faster** |
| MySQL | ~25s | ~3s | **8x faster** |
| Redis | ~20s | ~2s | **10x faster** |

The improvements come from container reuse - containers start once and
stay running instead of starting/stopping for each test.

## How to Use

```typescript
import * as dockerCompose from "../../docker/index.ts";

test("database test", async () => {
  // Ensure service is running (starts if needed)
  const pg = await dockerCompose.ensure("postgres_plain");
  
  // Connect using provided info
  const client = new PostgresClient({
    host: pg.host,
    port: pg.ports[5432],  // Mapped to random available port
  });
});
```

## Testing

All affected test suites have been run and verified:
- `bun test test/js/sql/sql.test.ts` 
- `bun test test/js/sql/sql-mysql*.test.ts` 
- `bun test test/js/bun/s3/s3.test.ts` 
- `bun test test/js/valkey/valkey.test.ts` 
- `bun test test/js/web/websocket/autobahn.test.ts` 

## Documentation

Comprehensive documentation added in `test/docker/README.md` including:
- Detailed explanation of Docker Compose for beginners
- Architecture overview
- Usage examples
- Debugging guide
- Migration guide for adding new services

## Notes

- The Redis reconnection test that's skipped was already broken before
this migration. It's a pre-existing issue with the Redis client's
reconnection logic, not related to Docker changes.
- All tests that were passing before continue to pass after migration.

2eebcee522 Fix DevServer HMR sourcemap offset issues (#22739)
## Summary
Fixes sourcemap offset issues in DevServer HMR mode that were causing
incorrect line number mappings when debugging.

## Problem

When using DevServer with HMR enabled, sourcemap line numbers were
consistently off by one or more lines when shown in Chrome DevTools. In
some cases, they were off when shown in the terminal as well.

## Solution

### 1. Remove magic +2 offset
Removed an arbitrary "+2" that was added to `runtime.line_count` in
SourceMapStore.zig. The comment said "magic fairy in my dreams said it
would align the source maps" - this was causing positions to be
incorrectly offset.

### 2. Fix double-increment bug
ErrorReportRequest.zig was incorrectly adding 1 to line numbers that
were already 1-based from the browser, causing an off-by-one error.

### 3. Improve type safety
Converted all line/column handling to use `bun.Ordinal` type instead of
raw `i32`, ensuring consistent 0-based vs 1-based conversions throughout
the codebase.

## Test plan
- [x] Added comprehensive sourcemap tests for complex error scenarios
- [x] Tested with React applications in dev mode
- [x] Verified line numbers match correctly in browser dev tools
- [x] Existing sourcemap tests continue to pass

661deb8eaf Fix MessagePort communication after transfer to Worker (#22638)
## Summary

Fixes #22635 - MessagePort communication fails after being transferred
to a Worker thread.
Fixes https://github.com/oven-sh/bun/issues/22636

The issue was that `MessagePort::addEventListener()` only called
`start()` for attribute listeners (like `onmessage = ...`) but not for
regular event listeners added via `addEventListener()` or the Node.js
EventEmitter wrapper (`.on('message', ...)`).

## Changes

- Modified `MessagePort::addEventListener()` to call `start()` for all
message event listeners, not just attribute listeners
- Added regression test for issue #22635

## Test Plan

- [x] Regression test added and passing
- [x] Original reproduction case from issue #22635 now works correctly
- [x] Existing MessagePort tests still pass

344a772ad5 Fix crypto.Sign exception with JWK EC keys and ieee-p1363 encoding (#22668)
Fixes https://github.com/oven-sh/bun/issues/21547

## Summary
- Fixes "Length out of range of buffer" error when using
`crypto.createSign().sign()` with JWK EC keys and `dsaEncoding:
"ieee-p1363"`
- The issue only occurred with the specific combination of JWK format
keys and IEEE P1363 signature encoding

## The Bug
When signing with EC keys in JWK format and requesting IEEE P1363
signature encoding, the code would:
1. Create a DER-encoded signature
2. Convert it to P1363 format (fixed-size raw r||s concatenation)
3. Replace the signature buffer with the P1363 buffer
4. **But incorrectly use the original DER signature length when creating
the final JSUint8Array**

This caused a buffer overflow since P1363 signatures are always 64 bytes
for P-256 curves, while DER signatures vary in length (typically 70-72
bytes).

## The Fix
Track the correct signature length after P1363 conversion and use it
when creating the final JSUint8Array.

## Test Plan
Added comprehensive tests in
`test/js/node/crypto/sign-jwk-ieee-p1363.test.ts` that:
- Verify the original failing case now works
- Test different encoding options (default DER, explicit DER, IEEE
P1363)
- Test with both JWK objects and KeyObject instances
- Verify signature lengths are correct for each format

The tests fail on the current main branch and pass with this fix.

dd9d1530da Fix crash when plugin onResolve returns undefined (#22670)
## Summary
Fixes #22199

When a plugin's `onResolve` handler returns `undefined` or `null`, Bun
should continue to the next plugin or use default resolution. However,
the code was crashing with a segmentation fault.

## The Bug
The crash occurred when:
1. A plugin's `onResolve` handler returned `undefined` (especially from
an async function as a fulfilled promise)
2. The code extracted the promise result but didn't check if it was
undefined before expecting it to be an object
3. This caused an improper exception to be thrown, leading to a crash

## The Fix
1. **Main fix**: Added a check for `undefined/null` after extracting the
result from a fulfilled promise, allowing the code to continue to the
next plugin
2. **Promise rejection fix**: Changed rejected promise handling to
return the promise itself instead of throwing an exception (which was
causing hangs)
3. **Exception handling**: Standardized exception throwing throughout
the file to use the proper `throwException` pattern

## Test Plan
Added comprehensive regression tests in
`test/regression/issue/22199.test.ts` that verify:
-  Async function returning `undefined` doesn't crash
-  Async function returning `null` doesn't crash  
-  Sync function returning `undefined` doesn't crash
-  Async function throwing an error properly shows the error

All tests:
- **Fail (crash) with release Bun**: Segmentation fault
- **Pass with this fix**: All test cases pass

## Verification
```bash
# Crashes without the fix
bun test test/regression/issue/22199.test.ts  

# Passes with the fix
bun bd test test/regression/issue/22199.test.ts
```

a09c45396e bun whoami as alias for bun pm whoami (currently reserved) (#22613)
### What does this PR do?

Previously, 'bun whoami' showed a reservation message indicating it was
reserved for future use. This change updates the command to execute 'bun
pm whoami' directly, making it consistent with npm's behavior.

Fixes #22614

Changes:
- Route 'bun whoami' to PackageManagerCommand instead of ReservedCommand
- Update PackageManagerCommand.exec to handle direct 'whoami' invocation

### How did you verify your code works?

- Add tests to verify both 'bun whoami' and 'bun pm whoami' work
correctly

0351bd5f28 Fix zstd decompression truncation for multi-frame responses (#22680)
## Summary

Fixes #20053

When a server sends zstd-compressed data with chunked transfer encoding,
each chunk may be compressed as a separate zstd frame. Previously, Bun's
zstd decompressor would stop after the first frame, causing responses to
be truncated at 16KB.

## The Fix

The fix modifies the zstd decompressor (`src/deps/zstd.zig`) to continue
decompression when a frame completes but input data remains. When
`ZSTD_decompressStream` returns 0 (frame complete), we now check if
there's more input data and reinitialize the decompressor to handle the
next frame.

## Testing

Added regression tests in `test/regression/issue/20053.test.ts` that:
1. Test multi-frame zstd decompression where two frames need to be
concatenated
2. Simulate the exact Hono + compression middleware scenario from the
original issue

Both tests fail without the fix (truncating at 16KB) and pass with the
fix.

## Verification

```bash
# Without fix (regular bun):
$ bun test test/regression/issue/20053.test.ts
 0 pass
 2 fail

# With fix (debug build):
$ bun bd test test/regression/issue/20053.test.ts  
 2 pass
 0 fail
```

6bafe2602e Fix Windows shell crash with && operator and external commands (#22651)
## What does this PR do?

Fixes https://github.com/oven-sh/bun/issues/22650
Fixes https://github.com/oven-sh/bun/issues/22615
Fixes https://github.com/oven-sh/bun/issues/22603
Fixes https://github.com/oven-sh/bun/issues/22602

Fixes a crash that occurred when running shell commands through `bun
run` (package.json scripts) on Windows that use the `&&` operator
followed by an external command.

### The Problem

The minimal reproduction was:
```bash
bun exec 'echo && node --version'
```

This would crash with: `panic(main thread): attempt to use null value`

### Root Causes

Two issues were causing the crash:

1. **Missing top_level_dir**: When `runPackageScriptForeground` creates
a MiniEventLoop for running package scripts, it wasn't setting the
`top_level_dir` field. This caused a null pointer dereference when the
shell tried to access it.

2. **MovableIfWindowsFd handling**: After PR #21800 introduced
`MovableIfWindowsFd` to handle file descriptor ownership on Windows, the
`IOWriter.fd` could be moved to libuv, leaving it null. When the shell
tried to spawn an external command after a `&&` operator, it would crash
trying to access this null fd.

### The Fix

1. Set `mini.top_level_dir = cwd` after initializing the MiniEventLoop
in `run_command.zig`
2. In `IO.zig`, when the fd has been moved to libuv (is null), use
`.inherit` for stdio instead of trying to pass the null fd

### How did you verify your code works?

- Added a regression test that reproduces the issue
- Verified the test fails without the fix and passes with it
- Tested the minimal reproduction command directly
- The fix correctly allows both commands in the `&&` chain to execute

```bash
# Before fix: crashes
> bun exec 'echo test && node --version'
panic(main thread): attempt to use null value

# After fix: works correctly
> bun exec 'echo test && node --version'
test
v22.4.1
```

### What does this PR do?

Evidently, Ubuntu turns them on by default. 

Claude:
```
> What is the typical overhead for glibcxx assertions?

⏺ The overhead of glibc/libstdc++ assertions can be significant, especially in
  performance-critical code:

  Typical Overhead Ranges:

  libstdc++ (C++ standard library) assertions:
  - 5-15% overall performance impact in typical applications
  - Up to 30-50% in container-heavy code (vectors, maps, etc.)
  - Iterator validity checks are particularly expensive

  glibc (C library) assertions:
  - 2-8% overall impact in typical applications
  - Up to 20% in malloc/free intensive code
  - Heap consistency checks, buffer overflow detection

ecd23df4ca Fix banner positioning with --format=cjs --target=bun (#22641)
## Summary
- Fixes incorrect banner positioning when using `--banner` with
`--format=cjs` and `--target=bun`
- Ensures Bun-specific comments (`// @bun @bun-cjs`) appear before user
banner content
- Properly extracts and positions hashbangs from banner content

## Problem
When using `--banner` with `--format=cjs --target=bun`, the banner was
incorrectly placed before the `// @bun @bun-cjs` comment and CJS wrapper
function, breaking the module format that Bun expects.

## Solution
Implemented proper ordering:
1. **Hashbang** (from source file or extracted from banner if it starts
with `#!`)
2. **@bun comments** (e.g., `// @bun`, `// @bun @bun-cjs`, `// @bun
@bytecode`)
3. **CJS wrapper** `(function(exports, require, module, __filename,
__dirname) {`
4. **Banner content** (excluding any extracted hashbang)

## Test plan
- [x] Added comprehensive tests for banner positioning with CJS/ESM and
Bun target
- [x] Tests cover hashbang extraction from banners
- [x] Tests verify proper ordering with bytecode generation
- [x] All existing tests pass

9b97dd11e2 Fix TTY reopening after stdin EOF (#22591)
## Summary
- Fixes ENXIO error when reopening `/dev/tty` after stdin reaches EOF
- Fixes ESPIPE error when reading from reopened TTY streams  
- Adds ref/unref methods to tty.ReadStream for socket-like behavior
- Enables TUI applications that read piped input then switch to
interactive TTY mode

## The Problem
TUI applications and interactive CLI tools have a pattern where they:
1. Read piped input as initial data: `echo "data" | tui-app`
2. After stdin ends, reopen `/dev/tty` for interactive session
3. Use the TTY for interactive input/output

This didn't work in Bun due to missing functionality:
- **ESPIPE error**: TTY ReadStreams incorrectly had `pos=0` causing
`pread()` syscall usage which fails on character devices
- **Missing methods**: tty.ReadStream lacked ref/unref methods that TUI
apps expect for socket-like behavior
- **Hardcoded isTTY**: tty.ReadStream always set `isTTY = true` even for
non-TTY file descriptors

## The Solution
1. **Fix ReadStream position**: For fd-based streams (like TTY), don't
default `start` to 0. This keeps `pos` undefined, ensuring `read()`
syscall is used instead of `pread()`.

2. **Add ref/unref methods**: Implement ref/unref on tty.ReadStream
prototype to match Node.js socket-like behavior, allowing TUI apps to
control event loop behavior.

3. **Dynamic isTTY check**: Use `isatty(fd)` to properly detect if the
file descriptor is actually a TTY.

## Test Results
```bash
$ bun test test/regression/issue/tty-reopen-after-stdin-eof.test.ts
✓ can reopen /dev/tty after stdin EOF for interactive session
✓ TTY ReadStream should not set position for character devices

$ bun test test/regression/issue/tty-readstream-ref-unref.test.ts
✓ tty.ReadStream should have ref/unref methods when opened on /dev/tty
✓ tty.ReadStream ref/unref should behave like Node.js

$ bun test test/regression/issue/tui-app-tty-pattern.test.ts
✓ TUI app pattern: read piped stdin then reopen /dev/tty
✓ tty.ReadStream handles non-TTY file descriptors correctly
```

## Compatibility
Tested against Node.js v24.3.0 - our behavior now matches:
-  Can reopen `/dev/tty` after stdin EOF
-  TTY ReadStream has `pos: undefined` and `start: undefined`
-  tty.ReadStream has ref/unref methods for socket-like behavior
-  `isTTY` is properly determined using `isatty(fd)`

9907c2e9fa fix(patch): add bounds checking to prevent segfault during patch application (#21939)
## Summary

- Fixes segmentation fault when applying patches with out-of-bounds line
numbers
- Adds comprehensive bounds checking in patch application logic
- Includes regression tests to prevent future issues

## Problem

Previously, malformed patches with line numbers beyond file bounds could
cause segmentation faults by attempting to access memory beyond
allocated array bounds in `addManyAt()` and `replaceRange()` calls.

## Solution

Added bounds validation at four key points in `src/patch.zig`:

1. **Hunk start position validation** (line 283-286) - Ensures hunk
starts within file bounds
2. **Context line validation** (line 294-297) - Validates context lines
exist within bounds
3. **Insertion position validation** (line 302-305) - Checks insertion
position is valid
4. **Deletion range validation** (line 317-320) - Ensures deletion range
is within bounds

All bounds violations now return `EINVAL` error gracefully instead of
crashing.

## Test Coverage

Added comprehensive regression tests in
`test/regression/issue/patch-bounds-check.test.ts`:

-  Out-of-bounds insertion attempts
-  Out-of-bounds deletion attempts  
-  Out-of-bounds context line validation
-  Valid patch application (positive test case)

Tests verify that `bun install` completes gracefully when encountering
malformed patches, with no crashes or memory corruption.

## Test Results

```
bun test v1.2.21
 Bounds checking working: bun install completed gracefully despite malformed patch
 Bounds checking working: bun install completed gracefully despite deletion beyond bounds
 Bounds checking working: bun install completed gracefully despite context lines beyond bounds

 4 pass
 0 fail
 22 expect() calls
Ran 4 tests across 1 file. [4.70s]
```

52b82cbe40 Fix: Allow napi_reference_unref to be called during GC (#22597)
## Summary
- Fixes #22596 where Nuxt crashes when building with rolldown-vite
- Aligns Bun's NAPI GC safety checks with Node.js behavior by only
enforcing them for experimental NAPI modules

## The Problem

Bun was incorrectly enforcing GC safety checks
(`NAPI_CHECK_ENV_NOT_IN_GC`) for ALL NAPI modules, regardless of
version. This caused crashes when regular production NAPI modules called
`napi_reference_unref` from finalizers, which is a common pattern in the
ecosystem (e.g., rolldown-vite).

The crash manifested as:
```
panic: Aborted
- napi.h:306: napi_reference_unref
```

## Root Cause: What We Did Wrong

Our previous implementation always enforced the GC check for all NAPI
modules:

**Before (incorrect):**
```cpp
// src/bun.js/bindings/napi.h:304-311
void checkGC() const
{
    NAPI_RELEASE_ASSERT(!inGC(),
        "Attempted to call a non-GC-safe function inside a NAPI finalizer...");
    // This was called for ALL modules, not just experimental ones
}
```

This was overly restrictive and didn't match Node.js's behavior, causing
legitimate use cases to crash.

## The Correct Solution: How Node.js Does It

After investigating Node.js source code, we found that Node.js **only
enforces GC safety checks for experimental NAPI modules**. Regular
production modules are allowed to call functions like
`napi_reference_unref` from finalizers for backward compatibility.

### Evidence from Node.js Source Code

**1. The CheckGCAccess implementation**
(`vendor/node/src/js_native_api_v8.h:132-143`):
```cpp
void CheckGCAccess() {
  if (module_api_version == NAPI_VERSION_EXPERIMENTAL && in_gc_finalizer) {
    // Only fails if BOTH conditions are true:
    // 1. Module is experimental (version 2147483647)
    // 2. Currently in GC finalizer
    v8impl::OnFatalError(...);
  }
}
```

**2. NAPI_VERSION_EXPERIMENTAL definition**
(`vendor/node/src/js_native_api.h:9`):
```cpp
#define NAPI_VERSION_EXPERIMENTAL 2147483647  // INT_MAX
```

**3. How it's used in napi_reference_unref**
(`vendor/node/src/js_native_api_v8.cc:2814-2819`):
```cpp
napi_status NAPI_CDECL napi_reference_unref(napi_env env,
                                            napi_ref ref,
                                            uint32_t* result) {
  CHECK_ENV_NOT_IN_GC(env);  // This check only fails for experimental modules
  // ... rest of implementation
}
```

## Our Fix: Match Node.js Behavior Exactly

**After (correct):**
```cpp
// src/bun.js/bindings/napi.h:304-315
void checkGC() const
{
    // Only enforce GC checks for experimental NAPI versions, matching Node.js behavior
    // See: https://github.com/nodejs/node/blob/main/src/js_native_api_v8.h#L132-L143
    if (m_napiModule.nm_version == NAPI_VERSION_EXPERIMENTAL) {
        NAPI_RELEASE_ASSERT(!inGC(), ...);
    }
    // Regular modules (version <= 8) can call napi_reference_unref from finalizers
}
```

This change means:
- **Regular NAPI modules** (version 8 and below):  Can call
`napi_reference_unref` from finalizers
- **Experimental NAPI modules** (version 2147483647):  Cannot call
`napi_reference_unref` from finalizers

## Why This Matters

Many existing NAPI modules in the ecosystem were written before the
stricter GC rules and rely on being able to call functions like
`napi_reference_unref` from finalizers. Node.js maintains backward
compatibility by only enforcing the stricter rules for modules that
explicitly opt into experimental features.

By not matching this behavior, Bun was breaking existing packages that
work fine in Node.js.

## Test Plan

Added comprehensive tests that verify both scenarios:

### 1. test_reference_unref_in_finalizer.c (Regular Module)
- Uses default NAPI version (8)
- Creates 100 objects with finalizers that call `napi_reference_unref`
- **Expected:** Works without crashing
- **Result:**  Passes with both Node.js and Bun (with fix)

### 2. test_reference_unref_in_finalizer_experimental.c (Experimental
Module)
- Uses `NAPI_VERSION_EXPERIMENTAL` (2147483647)
- Creates objects with finalizers that call `napi_reference_unref`
- **Expected:** Crashes with GC safety assertion
- **Result:**  Correctly fails with both Node.js and Bun (with fix)

## Verification

The tests prove our fix is correct:

```bash
# Regular module - should work
$ bun-debug --expose-gc main.js test_reference_unref_in_finalizer '[]'
 SUCCESS: napi_reference_unref worked in finalizers without crashing

# Experimental module - should fail
$ bun-debug --expose-gc main.js test_reference_unref_in_finalizer_experimental '[]'
 ASSERTION FAILED: Attempted to call a non-GC-safe function inside a NAPI finalizer
```

Both behaviors now match Node.js exactly.

## Impact

This fix:
1. Resolves crashes with rolldown-vite and similar packages
2. Maintains backward compatibility with the Node.js ecosystem
3. Still enforces safety for experimental NAPI features
4. Aligns Bun's behavior with Node.js's intentional design decisions

ee7608f7cf feat: support overriding Host, Sec-WebSocket-Key, and Sec-WebSocket-Protocol headers in WebSocket client (#22545)
## Summary

Adds support for overriding special WebSocket headers (`Host`,
`Sec-WebSocket-Key`, and `Sec-WebSocket-Protocol`) via the headers
option when creating a WebSocket connection.

## Changes

- Modified `WebSocketUpgradeClient.zig` to check for and use
user-provided special headers
- Added header value validation to prevent CRLF injection attacks
- Updated the NonUTF8Headers struct to automatically filter duplicate
headers
- When a custom `Sec-WebSocket-Protocol` header is provided, it properly
updates the subprotocols list for validation

## Implementation Details

The implementation adds minimal code by:
1. Using the existing `NonUTF8Headers` struct's methods to find valid
header overrides
2. Automatically filtering out WebSocket-specific headers in the format
method to prevent duplication
3. Maintaining a single, clean code path in `buildRequestBody()`

## Testing

Added comprehensive tests in `websocket-custom-headers.test.ts` that
verify:
- Custom Host header support
- Custom Sec-WebSocket-Key header support  
- Custom Sec-WebSocket-Protocol header support
- Header override behavior when both protocols array and header are
provided
- CRLF injection prevention
- Protection of system headers (Connection, Upgrade, etc.)
- Support for additional custom headers

All existing WebSocket tests continue to pass, ensuring backward
compatibility.

## Security

The implementation includes validation to:
- Reject header values with control characters (preventing CRLF
injection)
- Prevent users from overriding critical system headers like Connection
and Upgrade
- Validate header values according to RFC 7230 specifications

## Use Cases

This feature enables:
- Testing WebSocket servers with specific header requirements
- Connecting through proxies that require custom Host headers
- Implementing custom WebSocket subprotocol negotiation
- Debugging WebSocket connections with specific keys

Fixes #[issue_number]

e329316d44 Generate dependency versions header from CMake (#22561)
## Summary

This PR introduces a CMake-generated header file containing all
dependency versions, eliminating the need for C++ code to depend on
Zig-exported version constants.

## Changes

- **New CMake script**: `cmake/tools/GenerateDependencyVersions.cmake`
that:
  - Reads versions from the existing `generated_versions_list.zig` file
- Extracts semantic versions from header files where available
(libdeflate, zlib)
- Generates `bun_dependency_versions.h` with all dependency versions as
compile-time constants
  
- **Updated BunProcess.cpp**:
  - Now includes the CMake-generated `bun_dependency_versions.h`
  - Uses `BUN_VERSION_*` constants instead of `Bun__versions_*` 
  - Removes dependency on Zig-exported version constants

- **Build system updates**:
  - Added `GenerateDependencyVersions` to main CMakeLists.txt
  - Added build directory to include paths in BuildBun.cmake

## Benefits

 Single source of truth for dependency versions
 Versions accessible from C++ without Zig exports
 Automatic regeneration during CMake configuration
 Semantic versions shown where available (e.g., zlib 1.2.8 instead of
commit hash)
 Debug output file for verification

## Test Results

Verified that `process.versions` correctly shows all dependency
versions:

```javascript
$ bun -e "console.log(JSON.stringify(process.versions, null, 2))"
{
  "node": "24.3.0",

88a0002f7e feat: Add Redis HGET command (#22579)
## Summary

Implements the Redis `HGET` command which returns a single hash field
value directly, avoiding the need to destructure arrays when retrieving
individual fields.

Requested by user who pointed out that currently you have to use `HMGET`
which returns an array even for single values.

## Changes

- Add native `HGET` implementation in `js_valkey_functions.zig`
- Export function in `js_valkey.zig`
- Add JavaScript binding in `valkey.classes.ts`
- Add TypeScript definitions in `redis.d.ts`
- Add comprehensive tests demonstrating the difference

## Motivation

Currently, to get a single hash field value:
```js
// Before - requires array destructuring
const [value] = await redis.hmget("key", ["field"]);
```

With this PR:
```js
// After - direct value access
const value = await redis.hget("key", "field");
```

## Test Results

All tests passing locally with Redis server:
-  Returns single values (not arrays)
-  Returns `null` for non-existent fields/keys
-  Type definitions work correctly
-  ~2x faster than HMGET for single field access

## Notes

This follows the exact same pattern as existing hash commands like
`HMGET`, just simplified for the single-field case. The Redis `HGET`
command has been available since Redis 2.0.0.

3b7d1f7be2 Add --cwd to test error messages for AI agents (#22560)
## Summary
- Updates test error messages to include `--cwd=<path>` when AI agents
are detected
- Helps AI agents (like Claude Code) understand the working directory
context when encountering "not found" errors
- Normal user output remains unchanged

## Changes
When `Output.isAIAgent()` returns true (e.g., when `CLAUDECODE=1` or
`AGENT=1`), error messages in `test_command.zig` now include the current
working directory:

**Before (AI agent mode):**
```
Test filter "./nonexistent" had no matches
```

**After (AI agent mode):**
```
Test filter "./nonexistent" had no matches in --cwd="/workspace/bun"
```

**Normal mode (unchanged):**
```
Test filter "./nonexistent" had no matches
```

This applies to all "not found" error scenarios:
- When test filters don't match any files
- When no test files are found in the directory
- When scanning non-existent directories
- When filters don't match any test files

## Test plan
- [x] Verified error messages show actual directory paths (not literal
strings)
- [x] Tested with `CLAUDECODE=1` environment variable
- [x] Tested without AI agent flags to ensure normal output is unchanged
- [x] Tested from various directories (/, /tmp, /home, etc.)
- [x] Built successfully with `bun bd`

b3f5dd73da http(proxy): preserve TLS record ordering in proxy tunnel writes (#22417)
### What does this PR do?

Fixes a TLS corruption bug in CONNECT proxy tunneling for HTTPS uploads.
When a large request body is sent over a tunneled TLS connection, the
client could interleave direct socket writes with previously buffered
encrypted bytes, causing TLS records to be emitted out-of-order. Some
proxies/upstreams detect this as a MAC mismatch and terminate with
SSLV3_ALERT_BAD_RECORD_MAC, which surfaced to users as ECONNRESET ("The
socket connection was closed unexpectedly").

This change makes `ProxyTunnel.write` preserve strict FIFO ordering of
encrypted bytes: if any bytes are already buffered, we enqueue new bytes
instead of calling `socket.write` directly. Flushing continues
exclusively via `onWritable`, which writes the buffered stream in order.
This eliminates interleaving and restores correctness for large proxied
HTTPS POST requests.

### How did you verify your code works?

- Local reproduction using a minimal script that POSTs ~20MB over HTTPS
via an HTTP proxy (CONNECT):
- Before: frequent ECONNRESET. With detailed SSL logs, upstream sent
`SSLV3_ALERT_BAD_RECORD_MAC`.
  - After: requests complete successfully. Upstream responds as expected
  
- Verified small bodies and non-proxied HTTPS continue to work.
- Verified no linter issues and no unrelated code changes. The edit is
isolated to `src/http/ProxyTunnel.zig` and only affects the write path
to maintain TLS record ordering.

Rationale: TLS record boundaries must be preserved; mixing buffered data
with immediate writes risks fragmenting or reordering records under
backpressure. Enqueuing while buffered guarantees FIFO semantics and
avoids record corruption.

09c56c8ba8 Fix PostgreSQL StringBuilder assertion failure with empty error messages (#22558)
## Summary
- Fixed a debug build assertion failure in PostgreSQL error handling
when all error message fields are empty
- Added safety check before calling `StringBuilder.allocatedSlice()` to
handle zero-length messages
- Added regression test to prevent future occurrences

## The Problem
When PostgreSQL sends an error response with completely empty message
fields, the `ErrorResponse.toJS` function would:
1. Calculate `b.cap` but end up with `b.len = 0` (no actual content)
2. Call `b.allocatedSlice()[0..b.len]` unconditionally
3. Trigger an assertion in `StringBuilder.allocatedSlice()` that
requires `cap > 0`

This only affected debug builds since the assertion is compiled out in
release builds.

## The Fix
Check if `b.len > 0` before calling `allocatedSlice()`. If there's no
content, use an empty string instead.

## Test Plan
- [x] Added regression test that triggers the exact crash scenario
- [x] Verified test crashes without the fix (debug build)
- [x] Verified test passes with the fix
- [x] Confirmed release builds were not affected

b9f6a908f7 Fix tarball URL corruption in package manager (#22523)
## What does this PR do?

Fixes a bug where custom tarball URLs get corrupted during installation,
causing 404 errors when installing packages from private registries.

## How did you test this change?

- Added test case in `test/cli/install/bun-add.test.ts` that reproduces
the issue with nested tarball dependencies
- Verified the test fails without the fix and passes with it
- Tested with debug build to confirm the fix resolves the URL corruption

## The Problem

When installing packages from custom tarball URLs, the URLs were getting
mangled with cache folder patterns. The issue had two root causes:

1. **Temporary directory naming**: The extract_tarball.zig code was
including the full URL (including protocol) in temp directory names,
causing string truncation issues with StringOrTinyString's 31-byte limit

2. **Empty package names**: Tarball dependencies with empty package
names weren't being properly handled during deduplication, causing
incorrect package lookups

## The Fix

1. **In extract_tarball.zig**: Now properly extracts just the filename
from URLs using `std.fs.path.basename()` instead of including the full
URL in temp directory names

2. **In PackageManagerEnqueue.zig**: Added handling for empty package
names in tarball dependencies by falling back to the dependency name

description: Find duplicate GitHub issues
---
# Issue deduplication command
Find up to 3 likely duplicate issues for a given GitHub issue.
To do this, follow these steps precisely:
1. Use an agent to check if the GitHub issue (a) is closed, (b) does not need to be deduped (eg. because it is broad product feedback without a specific solution, or positive feedback), or (c) already has a duplicate detection comment (check for the exact HTML marker `<!-- dedupe-bot:marker -->` in the issue comments - ignore other bot comments). If so, do not proceed.
2. Use an agent to view a GitHub issue, and ask the agent to return a summary of the issue
3. Then, launch 5 parallel agents to search GitHub for duplicates of this issue, using diverse keywords and search approaches, using the summary from Step 2. **IMPORTANT**: Always scope searches with `repo:owner/repo` to constrain results to the current repository only.
4. Next, feed the results from Steps 2 and 3 into another agent, so that it can filter out false positives, that are likely not actually duplicates of the original issue. If there are no duplicates remaining, do not proceed.
5. Finally, comment back on the issue with a list of up to three duplicate issues (or zero, if there are no likely duplicates)
Notes (be sure to tell this to your agents, too):
- Use `gh` to interact with GitHub, rather than web fetch
- Do not use other tools, beyond `gh` (eg. don't use other MCP servers, file edit, etc.)
- Make a todo list first
- Always scope searches with `repo:owner/repo` to prevent cross-repo false positives
- For your comment, follow the following format precisely (assuming for this example that you found 3 suspected duplicates):
---
Found 3 possible duplicate issues:
1. <link to issue>
2. <link to issue>
3. <link to issue>
This issue will be automatically closed as a duplicate in 3 days.
- If your issue is a duplicate, please close it and 👍 the existing issue instead
- To prevent auto-closure, add a comment or 👎 this comment

- Always use `port: 0`. Do not hardcode ports. Do not use your own random port number function.
- Use `normalizeBunSnapshot` to normalize snapshot output of the test.
- NEVER write tests that check for no "panic" or "uncaught exception" or similar in the test output. That is NOT a valid test.
- Use `tempDir` from `"harness"` to create a temporary directory. **Do not** use `tmpdirSync` or `fs.mkdtempSync` to create temporary directories.
- When spawning processes, tests should expect(stdout).toBe(...) BEFORE expect(exitCode).toBe(0). This gives you a more useful error message on test failure.
- **CRITICAL**: Do not write flaky tests. Do not use `setTimeout` in tests. Instead, `await` the condition to be met. You are not testing the TIME PASSING, you are testing the CONDITION.
- **CRITICAL**: Verify your test fails with `USE_SYSTEM_BUN=1 bun test <file>` and passes with `bun bd test <file>`. Your test is NOT VALID if it passes with `USE_SYSTEM_BUN=1`.

- `internal/` - Internal modules not exposed to users
- `builtins/` - Core JavaScript builtins (streams, console, etc.)
### Special Syntax in Built-in Modules
1. **`$` prefix** - Access to private properties and JSC intrinsics:
```js
const arr = $Array.from(...); // Private global
map.$set(...); // Private method
const arr2 = $newArrayWithSize(5); // JSC intrinsic
```
2. **`require()`** - Must use string literals, resolved at compile time:
```js
const fs = require("fs"); // Directly loads by numeric ID
```
3. **Debug helpers**:
- `$debug()` - Like console.log but stripped in release builds
- `$assert()` - Assertions stripped in release builds
- `if($debug) {}` - Check if debug env var is set
4. **Platform detection**: `process.platform` and `process.arch` are inlined and dead-code eliminated
5. **Export syntax**: Use `export default` which gets converted to a return statement:
```js
export default {
readFile,
writeFile,
};
```
Note: These are NOT ES modules. The preprocessor converts `$` to `@` (JSC's actual syntax) and handles the special functions.
## CI
Bun uses BuildKite for CI. To get the status of a PR, you can use the following command:
```bash

# Bun React Integration Template
This is a Bun React application with built-in support for React Server Components, file-based routing, and static site generation.
## Project Structure
```
.
├── bun.app.ts # App configuration
├── pages/ # File-based routing directory
│ ├── index.tsx # Home page (/)
│ ├── about.tsx # Static route (/about)
│ ├── [slug].tsx # Dynamic route (/anything)
│ └── [...path].tsx # Catch-all route
└── public/ # Static assets
```
## Getting Started
### Running the Application
```bash
bun run dev # Start development server
bun run build # Build for production
bun run start # Start production server
```
## Configuration
The app is configured in `bun.app.ts`:
```tsx
// Basic configuration
export default { app: 'react' }
// Advanced configuration
export default {
app: {
framework: 'react',
// Add custom bundler options, plugins, etc.
}
}
```
## Features
### File-Based Routing
Create files in the `pages/` directory to automatically generate routes:
- `pages/index.tsx``/`
- `pages/about.tsx``/about`
- `pages/blog/index.tsx``/blog`
- `pages/blog/[slug].tsx``/blog/:slug` (dynamic)
- `pages/docs/[...path].tsx``/docs/*` (catch-all)
### React Server Components
This template supports both Server and Client components:
#### Server Components (default)
```tsx
// pages/server-page.tsx
// Server components can be async and fetch data directly
export default async function ServerPage() {
const data = await fetch('https://api.example.com/data').then(r => r.json());
return (
<div>
<h1>Server Component</h1>
<pre>{JSON.stringify(data, null, 2)}</pre>
</div>
);
}
```
#### Client Components
```tsx
// pages/client-page.tsx
"use client";
import { useState } from 'react';
export default function ClientPage() {
const [count, setCount] = useState(0);
return (
<div>
<h1>Client Component</h1>
<button onClick={() => setCount(count + 1)}>
Count: {count}
</button>
</div>
);
}
```
### Static Site Generation (SSG)
For dynamic routes, use `getStaticPaths` to pre-render pages at build time:
```tsx
// pages/blog/[slug].tsx
import type { GetStaticPaths } from 'bun';
export const getStaticPaths: GetStaticPaths<{ slug: string }> = async () => {
// Fetch all blog posts at build time
const posts = await fetch('https://api.example.com/posts').then(r => r.json());
return {
paths: posts.map((post: any) => ({
params: { slug: post.slug }
}))
};
};
export default function BlogPost({ params }: { params: { slug: string } }) {
return <h1>Blog Post: {params.slug}</h1>;
}
```
#### Examples of `getStaticPaths`
**Multi-parameter routes:**
```tsx
// pages/products/[category]/[id].tsx
export const getStaticPaths: GetStaticPaths<{
category: string;
id: string;
}> = async () => {
const products = await fetchProducts();
return {
paths: products.map(product => ({
params: {
category: product.category,
id: product.id
}
}))
};
};
```
**Catch-all routes:**
```tsx
// pages/docs/[...path].tsx
export const getStaticPaths: GetStaticPaths<{ path: string[] }> = async () => {
const docPaths = await getDocumentationPaths();
return {
paths: docPaths.map(docPath => ({
params: { path: docPath.split('/') }
}))
};
};
```
### Custom Response Handling
Server components can return custom `Response` objects:
```tsx
// pages/custom-response.tsx
export default async function CustomResponsePage({ searchParams }: any) {
// Rewrite to another page
if (searchParams.rewrite) {
return Response.render("/other-page");
}
// HTTP redirect
if (searchParams.redirect) {
return Response.redirect("/redirected");
}
// Custom response with headers
if (searchParams.custom) {
return Response(
<div>Custom Response</div>,
{
headers: {
'X-Custom-Header': 'value'
},
status: 200
}
);
}
return <div>Normal rendering</div>;
}
```
## Advanced Configuration
### Framework Options
You can customize the framework behavior in `bun.app.ts`:
```tsx
export default {
app: {
framework: 'react',
bundlerOptions: {
// Custom bundler options
},
staticRouters: ['public', 'static'],
reactFastRefresh: true,
serverComponents: {
// Server components configuration
},
plugins: [
// Bun plugins
]
}
}
```
### Available Framework Configuration
- `bundlerOptions`: Customize bundler behavior
- `fileSystemRouterTypes`: Configure routing conventions
- `staticRouters`: Directories to serve statically (default: `['public']`)
- `builtInModules`: Add or replace built-in modules
- `serverComponents`: React Server Components configuration
- `reactFastRefresh`: Enable/configure Fast Refresh for development
- `plugins`: Framework-specific bundler plugins
## Common Patterns
### Layout Components
Create a shared layout for your pages:
```tsx
// components/Layout.tsx
export default function Layout({ children }: { children: React.ReactNode }) {
return (
<html>
<head>
<title>My App</title>
</head>
<body>
<nav>
<a href="/">Home</a>
<a href="/about">About</a>
</nav>
<main>{children}</main>
</body>
</html>
);
}
```
### Data Fetching in Server Components
```tsx
// pages/products.tsx
async function getProducts() {
const response = await fetch('https://api.example.com/products', {
next: { revalidate: 3600 } // Cache for 1 hour
});
return response.json();
}
export default async function ProductsPage() {
const products = await getProducts();
return (
<div>
<h1>Products</h1>
<ul>
{products.map((product: any) => (
<li key={product.id}>{product.name}</li>
))}
</ul>
</div>
);
}
```
### Mixing Server and Client Components
```tsx
// pages/dashboard.tsx (Server Component)
import ClientCounter from '../components/ClientCounter';
export default async function Dashboard() {
const serverData = await fetchDashboardData();
return (
<div>
<h1>Dashboard</h1>
<div>Server-rendered data: {serverData.message}</div>
<ClientCounter initialCount={serverData.count} />
</div>
);
}
// components/ClientCounter.tsx (Client Component)
"use client";
import { useState } from 'react';
export default function ClientCounter({ initialCount }: { initialCount: number }) {
const [count, setCount] = useState(initialCount);
return (
<button onClick={() => setCount(c => c + 1)}>
Client count: {count}
</button>
);
}
```
## Development Tips
1. **Server Components are default**: Files in `pages/` are Server Components unless marked with `"use client"`
2. **Use `getStaticPaths` for dynamic routes**: Pre-render dynamic pages at build time for better performance
3. **Leverage Server Components**: Fetch data directly in components without client-side loading states
4. **Static assets**: Place static files in the `public/` directory
5. **Fast Refresh**: Enabled by default in development for instant feedback
## Experimental Features
⚠️ Note: These APIs are experimental and may change in future releases:
- `getStaticPaths` API
- Custom `Response` handling in Server Components
- Some framework configuration options
## Troubleshooting
### Common Issues
**Pages not routing correctly:**
- Ensure files are in the `pages/` directory
- Check file naming (use `.tsx` or `.jsx` extensions)
- Restart the dev server after adding new pages
**Client components not interactive:**
- Add `"use client"` directive at the top of the file
- Ensure client-only hooks (useState, useEffect) are in client components
**Build errors with dynamic routes:**
- Implement `getStaticPaths` for all dynamic route segments
- Ensure params match the file name pattern

- Batch up your changes
- Ensure zls is running with incremental watching for LSP errors (if you use VSCode and install Zig and run `bun run build` once to download Zig, this should just work)
- Prefer using the debugger ("CodeLLDB" in VSCode) to step through the code.
- Use debug logs. `BUN_DEBUG_<scope>=1` will enable debug logging for the corresponding `Output.scoped(.<scope>, false)` logs. You can also set `BUN_DEBUG_QUIET_LOGS=1` to disable all debug logging that isn't explicitly enabled. To dump debug lgos into a file, `BUN_DEBUG=<path-to-file>.log`.

# `install` benchmark
# Create T3 App
Requires [`hyperfine`](https://github.com/sharkdp/hyperfine). The goal of this benchmark is to compare installation performance of Bun with other package managers _when caches are hot_.
This is a [T3 Stack](https://create.t3.gg/) project bootstrapped with `create-t3-app`.

## What's next? How do I make an app with this?
To run the benchmark with the standard "install" command for each package manager:
We try to keep this project as simple as possible, so you can start with just the scaffolding we set up for you, and add additional things later when they become necessary.
```sh
$ hyperfine --prepare 'rm -rf node_modules' --warmup 1 --runs 3 'bun install' 'pnpm install' 'yarn' 'npm install'
```
If you are not familiar with the different technologies used in this project, please refer to the respective docs. If you still are in the wind, please join our [Discord](https://t3.gg/discord) and ask for help.
### With lockfile, offline mode

- [Prisma](https://prisma.io)
- [Drizzle](https://orm.drizzle.team)
- [Tailwind CSS](https://tailwindcss.com)
- [tRPC](https://trpc.io)
Even though all packages are cached, some tools may hit the npm API during the version resolution step. (This is not the same as re-downloading a package.) To entirely avoid network calls, the other package managers require `--prefer-offline/--offline` flag. To run the benchmark using "offline" mode:

To run the benchmark with offline mode but without lockfiles:
You can check out the [create-t3-app GitHub repository](https://github.com/t3-oss/create-t3-app) — your feedback and contributions are welcome!
```sh
$ hyperfine --prepare 'rm -rf node_modules' --warmup 1 'rm bun.lock && bun install' 'rm pnpm-lock.yaml && pnpm install --prefer-offline' 'rm yarn.lock && yarn --offline' 'rm package-lock.json && npm install --prefer-offline'
```
## How do I deploy this?
##
To check that the app is working as expected:
```
$ bun run dev
$ npm run dev
$ yarn dev
$ pnpm dev
```
Then visit [http://localhost:3000](http://localhost:3000).

## Pub/Sub
Bun provides native bindings for the [Redis
Pub/Sub](https://redis.io/docs/latest/develop/pubsub/) protocol. **New in Bun
1.2.23**
{% callout %}
**🚧** — The Redis Pub/Sub feature is experimental. Although we expect it to be
stable, we're currently actively looking for feedback and areas for improvement.
{% /callout %}
### Basic Usage
To get started publishing messages, you can set up a publisher in
`publisher.ts`:
```typescript#publisher.ts
import { RedisClient } from "bun";
const writer = new RedisClient("redis://localhost:6739");
await writer.connect();
writer.publish("general", "Hello everyone!");
writer.close();
```
In another file, create the subscriber in `subscriber.ts`:
```typescript#subscriber.ts
import { RedisClient } from "bun";
const listener = new RedisClient("redis://localhost:6739");
await listener.connect();
await listener.subscribe("general", (message, channel) => {
console.log(`Received: ${message}`);
});
```
In one shell, run your subscriber:
```bash
bun run subscriber.ts
```
and, in another, run your publisher:
```bash
bun run publisher.ts
```
{% callout %}
**Note:** The subscription mode takes over the `RedisClient` connection. A
client with subscriptions can only call `RedisClient.prototype.subscribe()`. In
other words, applications which need to message Redis need a separate
connection, acquirable through `.duplicate()`:
```typescript
import { RedisClient } from "bun";
const redis = new RedisClient("redis://localhost:6379");
await redis.connect();
const subscriber = await redis.duplicate();
await subscriber.subscribe("foo", () => {});
await redis.set("bar", "baz");
```
{% /callout %}
### Publishing
Publishing messages is done through the `publish()` method:
```typescript
await client.publish(channelName, message);
```
### Subscriptions
The Bun `RedisClient` allows you to subscribe to channels through the
`.subscribe()` method:
```typescript
await client.subscribe(channel, (message, channel) => {});
```
You can unsubscribe through the `.unsubscribe()` method:
```typescript
await client.unsubscribe(); // Unsubscribe from all channels.
await client.unsubscribe(channel); // Unsubscribe a particular channel.
await client.unsubscribe(channel, listener); // Unsubscribe a particular listener.
```

### `Bun.YAML.stringify()`
Convert a JavaScript value into a YAML string. The API signature matches `JSON.stringify`:
```ts
YAML.stringify(value, replacer?, space?)
```
- `value`: The value to convert to YAML
- `replacer`: Currently only `null` or `undefined` (function replacers not yet supported)
- `space`: Number of spaces for indentation (e.g., `2`) or a string to use for indentation. **Without this parameter, outputs flow-style (single-line) YAML**
#### Basic Usage
```ts
import { YAML } from "bun";
const data = {
name: "John Doe",
age: 30,
hobbies: ["reading", "coding"],
};
// Without space - outputs flow-style (single-line) YAML
console.log(YAML.stringify(data));
// {name: John Doe,age: 30,hobbies: [reading,coding]}
// With space=2 - outputs block-style (multi-line) YAML
console.log(YAML.stringify(data, null, 2));
// name: John Doe
// age: 30
// hobbies:
// - reading
// - coding
```
#### Output Styles
```ts

// [1,2,3]
// Block style (multi-line) - with indentation
console.log(YAML.stringify(arr, null, 2));
// - 1
// - 2
// - 3
```
#### String Quoting
`YAML.stringify()` automatically quotes strings when necessary:
- Strings that would be parsed as YAML keywords (`true`, `false`, `null`, `yes`, `no`, etc.)
- Strings that would be parsed as numbers
- Strings containing special characters or escape sequences
```ts
const examples = {
keyword: "true", // Will be quoted: "true"
number: "123", // Will be quoted: "123"
text: "hello world", // Won't be quoted: hello world
empty: "", // Will be quoted: ""
};
console.log(YAML.stringify(examples, null, 2));
// keyword: "true"
// number: "123"
// text: hello world
// empty: ""
```
#### Cycles and References
`YAML.stringify()` automatically detects and handles circular references using YAML anchors and aliases:
```ts
const obj = { name: "root" };
obj.self = obj; // Circular reference
const yamlString = YAML.stringify(obj, null, 2);
console.log(yamlString);
// &root
// name: root
// self:
// *root
// Objects with shared references
const shared = { id: 1 };
const data = {
first: shared,
second: shared,
};
console.log(YAML.stringify(data, null, 2));
// first:
// &first
// id: 1
// second:
// *first
```
#### Special Values
```ts
// Special numeric values
console.log(YAML.stringify(Infinity)); // .inf
console.log(YAML.stringify(-Infinity)); // -.inf
console.log(YAML.stringify(NaN)); // .nan
console.log(YAML.stringify(0)); // 0
console.log(YAML.stringify(-0)); // -0
// null and undefined
console.log(YAML.stringify(null)); // null
console.log(YAML.stringify(undefined)); // undefined (returns undefined, not a string)
// Booleans

### TypeScript Support
While Bun can import YAML files directly, TypeScript doesn't know the types of your YAML files by default. To add TypeScript support for your YAML imports, create a declaration file with `.d.ts` appended to the YAML filename (e.g., `config.yaml` → `config.yaml.d.ts`):
```yaml#config.yaml
features: "advanced"
server:
host: localhost
port: 3000
```
```ts#config.yaml.d.ts
const contents: {
features: string;
server: {
host: string;
port: number;
};
};
export = contents;
```
Now TypeScript will provide proper type checking and auto-completion:
```ts#app.ts
import config from "./config.yaml";
// TypeScript knows the types!
config.server.port; // number
config.server.host; // string
config.features; // string
// TypeScript will catch errors
config.server.unknown; // Error: Property 'unknown' does not exist
```
This approach works for both ES modules and CommonJS, giving you full type safety while Bun continues to handle the actual YAML parsing at runtime.
## Hot Reloading with YAML

## pnpm migration
Bun automatically migrates projects from pnpm to bun. When a `pnpm-lock.yaml` file is detected and no `bun.lock` file exists, Bun will automatically migrate the lockfile to `bun.lock` during installation. The original `pnpm-lock.yaml` file remains unmodified.

**Note**: Migration only runs when `bun.lock` is absent. There is currently no opt-out flag for pnpm migration.
The migration process handles:
### Lockfile Migration
- Converts `pnpm-lock.yaml` to `bun.lock` format
- Preserves package versions and resolution information
- Maintains dependency relationships and peer dependencies
- Handles patched dependencies with integrity hashes
### Workspace Configuration

```yaml
# pnpm-workspace.yaml
packages:
- "apps/*"
- "packages/*"
catalog:
react: ^18.0.0
typescript: ^5.0.0
catalogs:
build:
webpack: ^5.0.0
babel: ^7.0.0
```
The workspace packages list and catalogs are moved to the `workspaces` field in `package.json`:
```json
{
"workspaces": {
"packages": ["apps/*", "packages/*"],
"catalog": {
"react": "^18.0.0",
"typescript": "^5.0.0"
},
"catalogs": {
"build": {
"webpack": "^5.0.0",
"babel": "^7.0.0"
}
}
}
}
```
### Catalog Dependencies
Dependencies using pnpm's `catalog:` protocol are preserved:
```json
{
"dependencies": {
"react": "catalog:",
"webpack": "catalog:build"
}
}
```
### Configuration Migration
The following pnpm configuration is migrated from both `pnpm-lock.yaml` and `pnpm-workspace.yaml`:
- **Overrides**: Moved from `pnpm.overrides` to root-level `overrides` in `package.json`
- **Patched Dependencies**: Moved from `pnpm.patchedDependencies` to root-level `patchedDependencies` in `package.json`
- **Workspace Overrides**: Applied from `pnpm-workspace.yaml` to root `package.json`

- Requires pnpm lockfile version 7 or higher
- Workspace packages must have a `name` field in their `package.json`
- All catalog entries referenced by dependencies must exist in the catalogs definition
After migration, you can safely remove `pnpm-lock.yaml` and `pnpm-workspace.yaml` files.

For complete documentation refer to [Package manager > Global cache](https://bun.com/docs/install/cache).
## Minimum release age
To protect against supply chain attacks where malicious packages are quickly published, you can configure a minimum age requirement for npm packages. Package versions published more recently than the specified threshold (in seconds) will be filtered out during installation.
```bash
# Only install package versions published at least 3 days ago
$ bun add @types/bun --minimum-release-age 259200 # seconds
```
You can also configure this in `bunfig.toml`:
```toml
[install]
# Only install package versions published at least 3 days ago
minimumReleaseAge = 259200 # seconds
# Exclude trusted packages from the age gate
minimumReleaseAgeExcludes = ["@types/node", "typescript"]
```
When the minimum age filter is active:
- Only affects new package resolution - existing packages in `bun.lock` remain unchanged
- All dependencies (direct and transitive) are filtered to meet the age requirement when being resolved
- When versions are blocked by the age gate, a stability check detects rapid bugfix patterns
- If multiple versions were published close together just outside your age gate, it extends the filter to skip those potentially unstable versions and selects an older, more mature version
- Searches up to 7 days after the age gate, however if still finding rapid releases it ignores stability check
- Exact version requests (like `package@1.1.1`) still respect the age gate but bypass the stability check
- Versions without a `time` field are treated as passing the age check (npm registry should always provide timestamps)
For more advanced security scanning, including integration with services & custom filtering, see [Package manager > Security Scanner API](https://bun.com/docs/install/security-scanner-api).

## Concurrent test execution
By default, Bun runs all tests sequentially within each test file. You can enable concurrent execution to run async tests in parallel, significantly speeding up test suites with independent tests.
### `--concurrent` flag
Use the `--concurrent` flag to run all tests concurrently within their respective files:
```sh
$ bun test --concurrent
```
When this flag is enabled, all tests will run in parallel unless explicitly marked with `test.serial`.
### `--max-concurrency` flag
Control the maximum number of tests running simultaneously with the `--max-concurrency` flag:
```sh
# Limit to 4 concurrent tests
$ bun test --concurrent --max-concurrency 4
# Default: 20
$ bun test --concurrent
```
This helps prevent resource exhaustion when running many concurrent tests. The default value is 20.
### `test.concurrent`
Mark individual tests to run concurrently, even when the `--concurrent` flag is not used:
```ts
import { test, expect } from "bun:test";
// These tests run in parallel with each other
test.concurrent("concurrent test 1", async () => {
await fetch("/api/endpoint1");
expect(true).toBe(true);
});
test.concurrent("concurrent test 2", async () => {
await fetch("/api/endpoint2");
expect(true).toBe(true);
});
// This test runs sequentially
test("sequential test", () => {
expect(1 + 1).toBe(2);
});
```
### `test.serial`
Force tests to run sequentially, even when the `--concurrent` flag is enabled:
```ts
import { test, expect } from "bun:test";
let sharedState = 0;
// These tests must run in order
test.serial("first serial test", () => {
sharedState = 1;
expect(sharedState).toBe(1);
});
test.serial("second serial test", () => {
// Depends on the previous test
expect(sharedState).toBe(1);
sharedState = 2;
});
// This test can run concurrently if --concurrent is enabled
test("independent test", () => {
expect(true).toBe(true);

## Randomize test execution order
Use the `--randomize` flag to run tests in a random order. This helps detect tests that depend on shared state or execution order.
```sh
$ bun test --randomize
```
When using `--randomize`, the seed used for randomization will be displayed in the test summary:
```sh
$ bun test --randomize
# ... test output ...
--seed=12345
2 pass
8 fail
Ran 10 tests across 2 files. [50.00ms]
```
### Reproducible random order with `--seed`
Use the `--seed` flag to specify a seed for the randomization. This allows you to reproduce the same test order when debugging order-dependent failures.
```sh
# Reproduce a previous randomized run
$ bun test --seed 123456
```
The `--seed` flag implies `--randomize`, so you don't need to specify both. Using the same seed value will always produce the same test execution order, making it easier to debug intermittent failures caused by test interdependencies.
## Bail out with `--bail`
Use the `--bail` flag to abort the test run early after a pre-determined number of test failures. By default Bun will run all tests and report all failures, but sometimes in CI environments it's preferable to terminate earlier to reduce CPU usage.
