8136c0614d Add comprehensive documentation to doAccept function
Added detailed doc comment explaining:
- Function purpose: accepts already-open FD and attaches to server
- Parameters: file descriptor number via callframe.argument(0)
- Return behavior: js_undefined on success, throws bun.JSError on error
- Common use cases: systemd socket activation, Unix domain socket FD passing
- Error semantics: all validation checks and preconditions

Documentation follows project style with triple-slash comments and clearly
highlights what callers must provide and what errors to expect.

Addresses CodeRabbit review feedback.

cab0017920 Use direct argument access instead of array allocation
Replaced callframe.argumentsAsArray(1)[0] with callframe.argument(0)
to avoid unnecessary array allocation. Since we already validate
argumentsCount() >= 1, we can safely use direct argument access.

This is more efficient and follows the validation-then-access pattern
recommended by CodeRabbit.

All 7 tests pass with 281 expect() assertions.

4dfe3d4709 Add argument count validation and remove unreachable check
Addresses CodeRabbit review feedback:

1. Added explicit argument count validation using callframe.argumentsCount()
   before accessing argumentsAsArray(1)[0]. This ensures proper error
   handling when no arguments are provided.

2. Removed unreachable upper bound check (fd > maxInt(u32)). Since fd is
   of type i32, it can never exceed maxInt(u32) (4294967295), making that
   check redundant and unreachable.

The code now properly validates:
- Argument count (must have at least 1 argument)
- Argument type (must be a number)
- FD value (must be >= 0)

All 7 tests pass with 281 expect() assertions.

21c3ee79fa Add FD range validation and improve error message clarity
Addresses CodeRabbit review feedback:

1. Added upper bound validation (maxInt(u32)) before @intCast to prevent
   potential issues with extremely large i32 values

2. Simplified error message to be truthful about what we actually validate
   locally. Changed from claiming to validate "socket FD" and "SSL
   configuration" to simply reporting "Failed to accept file descriptor {d}"

   The actual validation of socket type and SSL compatibility happens in
   the C++ layer (us_socket_from_fd), not in this Zig code. The error
   message now accurately reflects what this function checks.

All 7 tests pass with 281 expect() assertions.

32ad95aa34 Improve error message for server.accept() failures
Enhanced the error message to include:
- The actual file descriptor number that failed
- Guidance on common failure causes (invalid socket FD, SSL mismatch)

This helps users diagnose issues more quickly when accept() fails.

ab9a588fd1 Add full SSL/TLS support to server.accept()
Implemented complete SSL support following the same pattern used
throughout libuwsockets.cpp:

- Added SSL branch that uses uWS::SSLApp and HttpContext<true>
- Uses HttpResponseData<true> for SSL sockets
- Properly initializes SSL socket extensions with placement new
- Triggers on_open callback for SSL connections
- Updated documentation to reflect SSL/TLS support

Both SSL and non-SSL sockets now work correctly with server.accept().
The implementation follows the exact same pattern as all other
uWebSockets operations in libuwsockets.cpp (get, post, listen, etc).

All 7 tests pass with 281 expect() assertions.

96a781769a Add close handler to binary upload test
Fixed potential hang in binary upload test if server closes connection
before 256 bytes are received:

- Added close handler that resolves promise if not already resolved
- Ensures test proceeds deterministically even if connection closes early
- Allows assertions to run and fail appropriately if response is incomplete

All 7 tests pass with 281 expect() calls.

fedaf66907 Fix remaining flaky tests by waiting for complete HTTP responses
Fixed two more potentially flaky tests that were resolving on first data
chunk instead of waiting for complete HTTP responses:

1. Basic HTTP request test:
   - Now parses Content-Length header
   - Waits until full response body is received before resolving
   - Adds close handler as fallback for Connection: close

2. Keep-Alive multiple requests test:
   - Implements proper HTTP response parser that handles pipelined responses
   - Maintains buffer and extracts complete responses one at a time
   - Supports multiple responses in single data chunk
   - Each response is pushed to array only when complete (headers + body)
   - Properly handles Connection: close by pushing remaining buffer

Both tests now robustly handle:
- Multi-chunk responses
- Pipelined responses
- Content-Length parsing
- Connection close scenarios

All 7 tests pass with 281 expect() calls.

26a987a81a Fix potentially flaky test by waiting for complete response body
The large POST test was resolving as soon as headers arrived, which could
cause flaky assertions if the body hadn't fully arrived yet.

Fixed by:
- Parsing Content-Length header from response
- Tracking body bytes received
- Only resolving promise when body length matches Content-Length
- Adding close handler as fallback for Connection: close responses

This ensures assertions always run against complete HTTP responses,
eliminating potential race conditions.

5e72f1c6c9 Document HttpContext pointer arithmetic technical debt
Added detailed comment explaining why we use pointer arithmetic to
access the private httpContext member of uWS::App:

- uWebSockets is a vendored library, so we can't easily add accessors
- The approach is consistent with patterns in App.h (lines 115, 127, 132)
- The TemplatedApp memory layout (httpContext as first member) is stable
- Similar pointer arithmetic is used elsewhere in libuwsockets.cpp

This addresses the code review suggestion to use an accessor function,
while acknowledging the constraint that modifying the vendored library
is not practical. The comment documents the technical debt for future
maintainers.

89d967f479 Address CodeRabbit review feedback
1. Remove unused #include <stdio.h> from socket.c
   - stdio.h was added for debug logging but is no longer needed

2. Fix SSL branch in uws_app_accept()
   - SSL/TLS socket acceptance now properly rejects with -1
   - Added comment explaining proper implementation would require
     us_socket_wrap_with_tls() + us_socket_open() for TLS handshake
   - Avoids unsafe construction of TLS HttpResponseData on non-TLS socket

3. Add #include <new> for placement new
   - Required for placement new syntax used in HttpResponseData initialization

4. Update accept() documentation with ownership semantics
   - Clarifies that app takes FD ownership on success
   - Caller retains ownership and must close FD on failure
   - Notes that SSL/TLS is not currently supported

5. Optimize test buffer allocations
   - Large POST body: Use Buffer.alloc(10000, 0x78).toString() instead of "x".repeat(10000)
   - Binary upload: Use Buffer.allocUnsafe(1000) and i & 0xff for faster allocation

All tests still pass (7 pass, 279 expect() calls).

b8a839b5f7 Mark server.accept() tests as todoIf(isWindows)
The server.accept() API is not supported on Windows because
us_socket_from_fd() is not implemented there (it returns 0 in the
Windows/libuv code path).

Socket pair tests now skip on Windows with test.todoIf(isWindows).
The API validation tests that don't use socket pairs still run on all
platforms.

6399d21ebc Add file upload test with binary data for server.accept()
Adds comprehensive test to verify both sending and receiving binary data
through an accepted file descriptor:

- Uploads 1000 bytes of binary data (sequential 0-255 pattern)
- Server processes the binary data and calculates checksum
- Server responds with 256 bytes of binary data (0-255)
- Client verifies binary integrity in both directions

This ensures that file descriptor acceptance works correctly for real-world
use cases like file uploads and binary protocol handling.

2a943b9518 Fix server.accept() by properly accessing HttpContext from App
The issue was that server.accept() was casting the uWebSockets App
pointer directly to us_socket_context_t*, but the App is a wrapper that
contains HttpContext as its first member. The HttpContext IS the socket
context, not the App itself.

This caused the event loop file descriptor to be read incorrectly (showing
as 0 instead of the actual epoll FD), which then caused epoll_ctl to fail
with EINVAL when trying to add socket pair file descriptors.

The fix accesses the httpContext pointer (first member of App struct) via
pointer arithmetic, then casts that to us_socket_context_t*. This gives us
the correct socket context with a properly initialized event loop.

All 6 tests now pass, including tests for:
- Basic HTTP request handling
- Multiple requests with Keep-Alive
- Large POST body handling
- Invalid file descriptor handling
- Argument validation

01d5f5069b Add server.accept() method to accept file descriptors
Implements server.accept(fd) method that allows accepting a file descriptor
number and integrating it as an HTTP connection to the server. This enables
use cases where file descriptors are obtained externally and need to be
handled by Bun's HTTP server.

Changes:
- Add accept() method to server.classes.ts
- Implement doAccept() in server.zig with FD validation
- Add uws_app_accept() C++ wrapper in libuwsockets.cpp
- Add Zig bindings in App.zig
- Create socket from FD using us_socket_from_fd()
- Initialize HttpResponseData and trigger on_open callback
- Add basic tests in server-accept.test.ts

The method validates the file descriptor, creates a socket from it,
and runs it through the same initialization code path as regular
connections, ensuring proper HTTP request handling.

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`

- `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

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
-  llvm-symbolizer integration works for debug builds
-  WTF printer is used for release builds
-  When begin_addr is not found, complete backtrace is used

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

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.

Also fixes potential index out of bounds if there are many invalid
sequences.

This also affects `TextEncoder`.

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.

3395774c8c improve(node:http): uncork after flushing headers to ensure data is sent immediately (#23413)
### 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:

6e3359dd16/packages/bun-uws/src/Loop.h (L57-L64)

A test already covers this scenario in
`test/js/node/test/parallel/test-http-flush-response-headers.js`.

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 }}`

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.

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.

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.

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

d292dcad26 fix(parser): typescript module parsing bug (#23284)
### What does this PR do?
A bug in our typescript parser was causing `module.foo = foo` to parse
as a typescript namespace. If it didn't end with a semicolon and there's
a statement on the next line it would cause a syntax error. Example:

```ts
module.foo = foo
foo.foo = foo
```

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]
```

624911180f fix(outdated): show catalog info without requiring --filter or -r (#23039)
## Summary

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

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

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`

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

  expect(a).toMatchInlineSnapshot();
}

  oops(1);
  oops(2);
});
```

```
2 |   expect(a).toMatchInlineSnapshot();
                                      ^

acceptable:

```ts

  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
- Converting ternary expressions used for control flow to if/else
statements

## Test plan

- [x] `bun lint` passes with no errors

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.

## Test plan

fail on invalid Git URL"` - passes

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

### What does this PR do?
Missing `.t_equals` and `.t_slash` checks. This matches esbuild.

```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

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)

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

depends on this, as it means C++ can pass a pointer to the `Blob` to Zig

`JSBlob`.

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.

## 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
same
4. File is properly regenerated when deleted or when content changes

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
```

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

f9a042f114 Improve --reporter flag help and error messages (#22900)
## 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
test --reporter=junit`
- [x] Tested error message for invalid coverage reporter:
`./build/debug/bun-debug test --coverage-reporter=invalid`
- [x] Verified junit reporter still works: `./build/debug/bun-debug test
--reporter=junit --reporter-outfile=/tmp/junit.xml`
- [x] Verified lcov coverage reporter still works:
`./build/debug/bun-debug test --coverage --coverage-reporter=lcov`

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(); });

// With this PR - guaranteed serial execution
test.serial("migrate database schema v1", async () => { await migrateV1(); });
test.serial("migrate database schema v2", async () => { await migrateV2(); });
test.serial("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.

### 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.

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 #20980, Fixes #21830, Fixes #5738, Fixes #19758, Fixes #12782,
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
```

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

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",
  "bun": "1.2.22-debug",
  "boringssl": "29a2cd359458c9384694b75456026e4b57e3e567",

  "zlib": "1.2.8",
  "libdeflate": "1.24",
  // ... all versions present and correct
}
```

## Generated Files

- `build/debug/bun_dependency_versions.h` - Header file with version
constants

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.

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

d7ca10e22f Remove unused function/class names when minifying (#22492)
## Summary
- Removes unused function and class expression names when
`--minify-syntax` is enabled during bundling
- Adds `--keep-names` flag to preserve original names when minifying
- Matches esbuild's minification behavior

## Problem
When minifying with `--minify-syntax`, Bun was keeping function and
class expression names even when they were never referenced, resulting
in larger bundle sizes compared to esbuild.

**Before:**
```js
export var AB = function A() { };
// Bun output: var AB = function A() {};
// esbuild output: var AB = function() {};
```

## Solution
This PR adds logic to remove unused function and class expression names
during minification, matching esbuild's behavior. Names are only removed
when:
- `--minify-syntax` is enabled
- Bundling is enabled (not transform-only mode)
- The scope doesn't contain direct eval (which could reference the name
dynamically)
- The symbol's usage count is 0

Additionally, a `--keep-names` flag has been added to preserve original
names when desired (useful for debugging or runtime reflection).

## Testing
- Updated existing test in `bundler_minify.test.ts` 
- All transpiler tests pass
- Manually verified output matches esbuild for various cases

## Examples
```bash
# Without --keep-names (names removed)
bun build --minify-syntax input.js
# var AB = function() {}

# With --keep-names (names preserved)  
bun build --minify-syntax --keep-names input.js
# var AB = function A() {}
```

dc3c8f79c4 Redis PUB/SUB (#21728)
### What does this PR do?

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).



### 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:

src="https://github.com/user-attachments/assets/36527386-c8fe-47f6-b69a-a11d4b614fa0"
/>


#### 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>`.

20dddd1819 feat(minify): optimize Error constructors by removing 'new' keyword (#22493)
## Summary
- Refactored `maybeMarkConstructorAsPure` to `minifyGlobalConstructor`
that returns `?Expr`
- Added minification optimizations for global constructors that work
identically with/without `new`
- Converts constructors to more compact forms: `new Object()` → `{}`,
`new Array()` → `[]`, etc.
- Fixed issue where minification was incorrectly applied to runtime
node_modules code

## Details

This PR refactors the existing `maybeMarkConstructorAsPure` function to
`minifyGlobalConstructor` and changes it to return an optional
expression. This enables powerful minification optimizations for global
constructors.

### Optimizations Added:

#### 1. Error Constructors (4 bytes saved each)
- `new Error(...)` → `Error(...)`
- `new TypeError(...)` → `TypeError(...)`
- `new SyntaxError(...)` → `SyntaxError(...)`
- `new RangeError(...)` → `RangeError(...)`
- `new ReferenceError(...)` → `ReferenceError(...)`
- `new EvalError(...)` → `EvalError(...)`
- `new URIError(...)` → `URIError(...)`
- `new AggregateError(...)` → `AggregateError(...)`

#### 2. Object Constructor
- `new Object()` → `{}` (11 bytes saved)
- `new Object({a: 1})` → `{a: 1}` (11 bytes saved)
- `new Object([1, 2])` → `[1, 2]` (11 bytes saved)
- `new Object(null)` → `{}` (15 bytes saved)
- `new Object(undefined)` → `{}` (20 bytes saved)

#### 3. Array Constructor
- `new Array()` → `[]` (10 bytes saved)
- `new Array(1, 2, 3)` → `[1, 2, 3]` (9 bytes saved)
- `new Array(5)` → `Array(5)` (4 bytes saved, preserves sparse array
semantics)

#### 4. Function and RegExp Constructors
- `new Function(...)` → `Function(...)` (4 bytes saved)
- `new RegExp(...)` → `RegExp(...)` (4 bytes saved)

### Important Fixes:
- Added check to prevent minification of node_modules code at runtime
(only applies during bundling)
- Preserved sparse array semantics for `new Array(number)`
- Extracted `callFromNew` helper to reduce code duplication

### Size Impact:
- React SSR bundle: 463 bytes saved
- Each optimization safely preserves JavaScript semantics

## Test plan
 All tests pass:
- Added comprehensive tests in `bundler_minify.test.ts`
- Verified Error constructors work identically with/without `new`
- Tested Object/Array literal conversions
- Ensured sparse array semantics are preserved
- Updated source map positions in `bundler_npm.test.ts`

594b03c275 Fix: Socket.write() fails with Uint8Array (#22482)
## Summary
- Fixes #22481 where `Socket.write()` was throwing
"Stream._isArrayBufferView is not a function" when passed a Uint8Array
- The helper methods were being added to the wrong Stream export
- Now adds them directly to the Stream constructor in
`internal/streams/legacy.ts` where they're actually used

## Test plan
- Added regression test in `test/regression/issue/22481.test.ts`
- Test verifies that sockets can write Uint8Array, Buffer, and other
TypedArray views
- All tests pass with the fix

18e4da1903 Fix memory leak in JSBundlerPlugin and remove a couple JSC::Strong (#22488)
### What does this PR do?

Since `JSBundlerPlugin` did not inherit from `JSDestructibleObject`, it
did not call the destructor. This means it never called the destructor
on `BundlerPlugin`, which means it leaked the WTF::Vector of RegExp and
strings.

This adds a small `WriteBarrierList` abstraction that is a
`WriteBarrier` guarded by the owning `JSCell`'s `cellLock()` that has a
`visitChildren` function. This also removes two usages of `JSC::Strong`
on the `Zig::GlboalObject` and replaces them with the
`WriteBarrierList`.

### How did you verify your code works?

Added a test. The test did not previously fail. But it's still good to
have a test that checks the onLoad callbacks are finalized.

7a199276fb implement typeof undefined minification optimization (#22278)
## Summary

Implements the `typeof undefined === 'u'` minification optimization from
esbuild in Bun's minifier, and fixes dead code elimination (DCE) for
typeof comparisons with string literals.

### Part 1: Minification Optimization
This optimization transforms:
- `typeof x === "undefined"` → `typeof x > "u"`
- `typeof x !== "undefined"` → `typeof x < "u"`
- `typeof x == "undefined"` → `typeof x > "u"`
- `typeof x != "undefined"` → `typeof x < "u"`

Also handles flipped operands (`"undefined" === typeof x`).

### Part 2: DCE Fix for Typeof Comparisons
Fixed dead code elimination to properly handle typeof comparisons with
strings (e.g., `typeof x <= 'u'`). These patterns can now be correctly
eliminated when they reference unbound identifiers that would throw
ReferenceErrors.

## Before/After

### Minification
Before:
```javascript
console.log(typeof x === "undefined");
```

After:
```javascript
console.log(typeof x > "u");
```

### Dead Code Elimination
Before (incorrectly kept):
```javascript
var REMOVE_1 = typeof x <= 'u' ? x : null;
```

After (correctly eliminated):
```javascript
// removed
```

## Implementation

### Minification
- Added `tryOptimizeTypeofUndefined` function in
`src/ast/visitBinaryExpression.zig`
- Handles all 4 equality operators and both operand orders
- Only optimizes when both sides match the expected pattern (typeof
expression + "undefined" string)
- Replaces "undefined" with "u" and changes operators to `>` (for
equality) or `<` (for inequality)

### DCE Improvements
- Extended `isSideEffectFreeUnboundIdentifierRef` in `src/ast/P.zig` to
handle comparison operators (`<`, `>`, `<=`, `>=`)
- Added comparison operators to `simplifyUnusedExpr` in
`src/ast/SideEffects.zig`
- Now correctly identifies when typeof comparisons guard against
undefined references

## Test Plan

 Added comprehensive test in `test/bundler/bundler_minify.test.ts` that
verifies:
- All 8 variations work correctly (4 operators × 2 operand orders)
- Cases that shouldn't be optimized are left unchanged
- Matches esbuild's behavior exactly using inline snapshots

 DCE test `dce/DCETypeOfCompareStringGuardCondition` now passes:
- Correctly eliminates dead code with typeof comparison patterns
- Maintains compatibility with esbuild's DCE behavior

63c4d8f68f Fix TypeScript syntax not working with 'ts' loader in BunPlugin (#22460)
## Summary

Fixes #12548 - TypeScript syntax doesn't work in BunPlugin when using
`loader: 'ts'`

## The Problem

When creating a virtual module with `build.module()` and specifying
`loader: 'ts'`, TypeScript syntax like `import { type TSchema }` would
fail to parse with errors like:

```
error: Expected "}" but found "TSchema"
error: Expected "from" but found "}"
```

The same code worked fine when using `loader: 'tsx'`, indicating the
TypeScript parser wasn't being configured correctly for `.ts` files.

## Root Cause

The bug was caused by an enum value mismatch between C++ and Zig:

### Before (Incorrect)
- **C++ (`headers-handwritten.h`)**: `jsx=0, js=1, ts=2, tsx=3, ...`
- **Zig API (`api/schema.zig`)**: `jsx=1, js=2, ts=3, tsx=4, ...`  
- **Zig Internal (`options.zig`)**: `jsx=0, js=1, ts=2, tsx=3, ...`

When a plugin returned `loader: 'ts'`, the C++ code correctly parsed the
string "ts" and set `BunLoaderTypeTS=2`. However, when this value was
passed to Zig's `Bun__transpileVirtualModule` function (which expects
`api.Loader`), the value `2` was interpreted as `api.Loader.js` instead
of `api.Loader.ts`, causing the TypeScript parser to not be enabled.

### Design Context

The codebase has two loader enum systems by design:
- **`api.Loader`**: External API interface used for C++/Zig
communication
- **`options.Loader`**: Internal representation used within Zig

The conversion between them happens via `options.Loader.fromAPI()` and
`.toAPI()` functions. The C++ layer should use `api.Loader` values since
that's what the interface functions expect.

## The Fix

1. **Aligned enum values**: Updated the `BunLoaderType` constants in
`headers-handwritten.h` to match the values in `api/schema.zig`,
ensuring C++ and Zig agree on the enum values
2. **Removed unnecessary assertion**: Removed the assertion that
`plugin_runner` must be non-null for virtual modules, as it's not
actually required for modules created via `build.module()`
3. **Added regression test**: Created comprehensive test in
`test/regression/issue/12548.test.ts` that verifies TypeScript syntax
works correctly with the `'ts'` loader

## Testing

### New Tests Pass
-  `test/regression/issue/12548.test.ts` - 2 tests verifying TypeScript
type imports work with `'ts'` loader

### Existing Tests Still Pass
-  `test/js/bun/plugin/plugins.test.ts` - 28 pass
-  `test/bundler/bundler_plugin.test.ts` - 52 pass  
-  `test/bundler/bundler_loader.test.ts` - 27 pass
-  `test/bundler/esbuild/loader.test.ts` - 10 pass
-  `test/bundler/bundler_plugin_chain.test.ts` - 13 pass

### Manual Verification
```javascript
// This now works correctly with loader: 'ts'
Bun.plugin({
  setup(build) {
    build.module('hi', () => ({
      contents: "import { type TSchema } from '@sinclair/typebox'",
      loader: 'ts',  //  Works now (previously failed)
    }))
  },
})
```

ae6ad1c04a Fix N-API compatibility issues: strict_equals, call_function, and array_with_length (#22459)
## Summary
- Fixed napi_strict_equals to use JavaScript === operator semantics
instead of Object.is()
- Added missing recv parameter validation in napi_call_function
- Fixed napi_create_array_with_length boundary handling to match Node.js
behavior

## Changes

### napi_strict_equals
- Changed from isSameValue (Object.is semantics) to isStrictEqual (===
semantics)
- Now correctly implements JavaScript strict equality: NaN !== NaN and
-0 === 0
- Added new JSC binding JSC__JSValue__isStrictEqual to support this

### napi_call_function
- Added NAPI_CHECK_ARG(env, recv) validation to match Node.js behavior
- Prevents crashes when recv parameter is null/undefined

### napi_create_array_with_length
- Fixed boundary value handling for negative and oversized lengths
- Now correctly clamps negative signed values to 0 (e.g., when size_t
0x80000000 becomes negative in i32)
- Matches Node.js V8 implementation which casts size_t to int then
clamps to min 0

## Test plan
- [x] Added comprehensive C++ tests in
test/napi/napi-app/standalone_tests.cpp
- [x] Added corresponding JavaScript tests in test/napi/napi.test.ts
- [x] Tests verify:
  - Strict equality semantics (NaN, -0/0, normal values)
  - Null recv parameter handling
- Array creation with boundary values (negative, oversized, edge cases)

301ec28a65 replace jsDoubleNumber with jsNumber to use NumberTag if possible (#22476)
### What does this PR do?
Replaces usages of `jsDoubleNumber` with `jsNumber` in places where the
value is likely to be either a double or strict int32. `jsNumber` will
decide to use `NumberTag` or `EncodeAsDouble`.

If the number is used in a lot of arithmetic this could boost
performance (related #18585).

5b842ade1d Fix cookie.isExpired() returning false for Unix epoch (#22478)
## Summary
Fixes #22475 

`cookie.isExpired()` was incorrectly returning `false` for cookies with
`Expires` set to Unix epoch (Thu, 01 Jan 1970 00:00:00 GMT).

## The Problem
The bug had two parts:

1. **In `Cookie::isExpired()`**: The condition `m_expires < 1`
incorrectly treated Unix epoch (0) as a session cookie instead of an
expired cookie.

2. **In `Cookie::parse()`**: When parsing date strings that evaluate to
0 (Unix epoch), the code used implicit boolean conversion which treated
0 as false, preventing the expires value from being set.

## The Fix
- Removed the `m_expires < 1` check from `isExpired()`, keeping only the
check for `emptyExpiresAtValue` to identify session cookies
- Fixed date parsing to use `std::isfinite()` instead of implicit
boolean conversion, properly handling Unix epoch (0)

## Test Plan
- Added regression test in `test/regression/issue/22475.test.ts`
covering Unix epoch and edge cases
- All existing cookie tests pass (`bun bd test test/js/bun/cookie/`)
- Manually tested the reported issue from #22475

```javascript
const cookies = [
  'a=; Expires=Thu, 01 Jan 1970 00:00:00 GMT',
  'b=; Expires=Thu, 01 Jan 1970 00:00:01 GMT'
];

for (const _cookie of cookies) {
  const cookie = new Bun.Cookie(_cookie);
  console.log(cookie.name, cookie.expires, cookie.isExpired());
}
```

Now correctly outputs:
```
a 1970-01-01T00:00:00.000Z true
b 1970-01-01T00:00:01.000Z true
```

The constructor was using `isUtf8` instead of `isAscii`.

Instead of this change maybe we should remove the constructors for
`isAscii` and `isUtf8`. It looks like we do this for most native
functions, but would be more breaking than correcting the current bug.

6c3005e412 feat: add --workspaces support for bun run (#22415)
## Summary

This PR implements the `--workspaces` flag for the `bun run` command,
allowing scripts to be run in all workspace packages as defined in the
`"workspaces"` field in package.json.

Fixes the infinite loop issue reported in
https://github.com/threepointone/bun-workspace-bug-repro

## Changes

- Added `--workspaces` flag to run scripts in all workspace packages
- Added `--if-present` flag to gracefully skip packages without the
script
- Root package is excluded when using `--workspaces` to prevent infinite
recursion
- Added comprehensive tests for the new functionality

## Usage

```bash
# Run "test" script in all workspace packages
bun run --workspaces test

# Skip packages that don't have the script
bun run --workspaces --if-present build

# Combine with filters
bun run --filter="@scope/*" test
```

## Behavior

The `--workspaces` flag must come **before** the script name (matching
npm's behavior):
-  `bun run --workspaces test` 
-  `bun run test --workspaces` (treated as passthrough to script)

## Test Plan

- [x] Added test cases in `test/cli/run/workspaces.test.ts`
- [x] Verified fix for infinite loop issue in
https://github.com/threepointone/bun-workspace-bug-repro
- [x] Tested with `--if-present` flag
- [x] All tests pass locally

40b310c208 Fix child_process stdio properties not enumerable for Object.assign() compatibility (#22322)
## Summary

Fixes compatibility issue with Node.js libraries that use
`Object.assign(promise, childProcess)` pattern, specifically `tinyspawn`
(used by `youtube-dl-exec`).

## Problem

In Node.js, child process stdio properties (`stdin`, `stdout`, `stderr`,
`stdio`) are enumerable own properties that can be copied by
`Object.assign()`. In Bun, they were non-enumerable getters on the
prototype, causing `Object.assign()` to fail copying them.

This broke libraries like:
- `tinyspawn` - uses `Object.assign(promise, childProcess)` to merge
properties
- `youtube-dl-exec` - depends on tinyspawn internally

## Solution

Make stdio properties enumerable own properties during spawn while
preserving:
-  Lazy initialization (streams created only when accessed)
-  Original getter functionality and caching
-  Performance (minimal overhead)

## Testing

- Added comprehensive regression tests
- Verified compatibility with `tinyspawn` and `youtube-dl-exec`
- Existing child_process tests still pass

edb7214e6c feat(perf_hooks): Implement monitorEventLoopDelay() for Node.js compatibility (#22429)
## Summary
This PR implements `perf_hooks.monitorEventLoopDelay()` for Node.js
compatibility, enabling monitoring of event loop delays and collection
of performance metrics via histograms.

Fixes #17650

## Implementation Details

### JavaScript Layer (`perf_hooks.ts`)
- Added `IntervalHistogram` class with:
  - `enable()` / `disable()` methods with proper state tracking
  - `reset()` method to clear histogram data
  - Properties: `min`, `max`, `mean`, `stddev`, `exceeds`, `percentiles`
  - `percentile(p)` method with validation
- Full input validation matching Node.js behavior (TypeError vs
RangeError)

### C++ Bindings (`JSNodePerformanceHooksHistogramPrototype.cpp`)
- `jsFunction_monitorEventLoopDelay` - Creates histogram for event loop
monitoring
- `jsFunction_enableEventLoopDelay` - Enables monitoring and starts
timer
- `jsFunction_disableEventLoopDelay` - Disables monitoring and stops
timer
- `JSNodePerformanceHooksHistogram_recordDelay` - Records delay
measurements

### Zig Implementation (`EventLoopDelayMonitor.zig`)
- Embedded `EventLoopTimer` that fires periodically based on resolution
- Tracks last fire time and calculates delay between expected vs actual
- Records delays > 0 to the histogram
- Integrates seamlessly with existing Timer system

## Testing
 All tests pass:
- Custom test suite with 8 comprehensive tests
- Adapted Node.js core test for full compatibility
- Tests cover enable/disable behavior, percentiles, error handling, and
delay recording

## Test plan
- [x] Run `bun test
test/js/node/perf_hooks/test-monitorEventLoopDelay.test.js`
- [x] Run adapted Node.js test
`test/js/node/test/sequential/test-performance-eventloopdelay-adapted.test.js`
- [x] Verify proper error handling for invalid arguments
- [x] Confirm delay measurements are recorded correctly

d5431fcfe6 Fix Windows compilation issues with embedded resources and relative paths (#22365)
## Summary
- Fixed embedded resource path resolution when using
`Bun.build({compile: true})` API for Windows targets
- Fixed relative path handling for `--outfile` parameter in compilation

## Details

This PR fixes two regressions introduced after v1.2.19 in the
`Bun.build({compile})` feature:

### 1. Embedded Resource Path Issue
When using `Bun.build({compile: true})`, the module prefix wasn't being
set to the target-specific base path, causing embedded resources to fail
with "ENOENT: no such file or directory" errors on Windows (e.g.,
`B:/~BUN/root/` paths).

**Fix**: Ensure the target-specific base path is used as the module
prefix in `doCompilation`, matching the behavior of the CLI build
command.

### 2. PE Metadata with Relative Paths
When using relative paths with `--outfile` (e.g.,
`--outfile=forward/slash` or `--outfile=back\\slash`), the compilation
would fail with "FailedToLoadExecutable" error.

**Fix**: Ensure relative paths are properly converted to absolute paths
before PE metadata operations.

## Test Plan
- [x] Tested `Bun.build({compile: true})` with embedded resources
- [x] Tested relative path handling with nested directories
- [x] Verified compiled executables run correctly

42cec2f0e2 Remove 'Original Filename' metadata from Windows executables (#22389)
## Summary
- Automatically removes the "Original Filename" field from Windows
single-file executables
- Prevents compiled executables from incorrectly showing "bun.exe" as
their original filename
- Adds comprehensive tests to verify the field is properly removed

## Problem
When creating single-file executables on Windows, the "Original
Filename" metadata field was showing "bun.exe" regardless of the actual
executable name. This was confusing for users and incorrect from a
metadata perspective.

## Solution
Modified `rescle__setWindowsMetadata()` in
`src/bun.js/bindings/windows/rescle-binding.cpp` to automatically clear
the `OriginalFilename` field by setting it to an empty string whenever
Windows metadata is updated during executable creation.

## Test Plan
- [x] Added tests in `test/bundler/compile-windows-metadata.test.ts` to
verify:
  - Original Filename field is empty in basic compilation
- Original Filename field remains empty even when all other metadata is
set
- [x] Verified cross-platform compilation with `bun run zig:check-all` -
all platforms compile successfully

The tests will run on Windows CI to verify the behavior is correct.

72490281e5 fix: handle empty chunked gzip responses correctly (#22360)
## Summary
Fixes #18413 - Empty chunked gzip responses were causing `Decompression
error: ShortRead`

## The Issue
When a server sends an empty response with `Content-Encoding: gzip` and
`Transfer-Encoding: chunked`, Bun was throwing a `ShortRead` error. This
occurred because the code was checking if `avail_in == 0` (no input
data) and immediately returning an error, without attempting to
decompress what could be a valid empty gzip stream.

## The Fix
Instead of checking `avail_in == 0` before calling `inflate()`, we now:
1. Always call `inflate()` even when `avail_in == 0` 
2. Check the return code from `inflate()`
3. If it returns `BufError` with `avail_in == 0`, then we truly need
more data and return `ShortRead`
4. If it returns `StreamEnd`, it was a valid empty gzip stream and we
finish successfully

This approach correctly distinguishes between "no data yet" and "valid
empty gzip stream".

## Why This Works
- A valid empty gzip stream still has headers and trailers (~20 bytes)
- The zlib `inflate()` function can handle empty streams correctly  
- `BufError` with `avail_in == 0` specifically means "need more input
data"

## Test Plan
 Added regression test in `test/regression/issue/18413.test.ts`
covering:
- Empty chunked gzip response
- Empty non-chunked gzip response  
- Empty chunked response without gzip

 Verified all existing gzip-related tests still pass
 Tested with the original failing case from the issue

e1de7563e1 Fix PostgreSQL TIME and TIMETZ binary format handling (#22354)
## Summary
- Fixes binary format handling for PostgreSQL TIME and TIMETZ data types
- Resolves issue where time values were returned as garbled binary data
with null bytes

## Problem
When PostgreSQL returns TIME or TIMETZ columns in binary format, Bun.sql
was not properly converting them from their binary representation
(microseconds since midnight) to readable time strings. This resulted in
corrupted output like `\u0000\u0000\u0000\u0000\u0076` instead of proper
time values like `09:00:00`.

## Solution
Added proper binary format decoding for:
- **TIME (OID 1083)**: Converts 8 bytes of microseconds since midnight
to `HH:MM:SS.ffffff` format
- **TIMETZ (OID 1266)**: Converts 8 bytes of microseconds + 4 bytes of
timezone offset to `HH:MM:SS.ffffff±HH:MM` format

## Changes
- Added binary format handling in `src/sql/postgres/DataCell.zig` for
TIME and TIMETZ types
- Added `InvalidTimeFormat` error to `AnyPostgresError` error set
- Properly formats microseconds with trailing zero removal
- Handles timezone offsets correctly (PostgreSQL uses negative values
for positive UTC offsets)

## Test plan
Added comprehensive tests in `test/js/bun/sql/postgres-time.test.ts`:
- [x] TIME and TIMETZ column values with various formats
- [x] NULL handling
- [x] Array types (TIME[] and TIMETZ[])
- [x] JSONB structures containing time strings
- [x] Verification that no binary/null bytes appear in output

All tests pass locally with PostgreSQL.

3d361c8b49 Static allocator polymorphism (#22227)
* Define a generic allocator interface to enable static polymorphism for
allocators (see `GenericAllocator` in `src/allocators.zig`). Note that
`std.mem.Allocator` itself is considered a generic allocator.
* Add utilities to `bun.allocators` for working with generic allocators.
* Add a new namespace, `bun.memory`, with basic utilities for working
with memory and objects (`create`, `destroy`, `initDefault`, `deinit`).
* Add `bun.DefaultAllocator`, a zero-sized generic allocator type whose
`allocator` method simply returns `bun.default_allocator`.
* Implement the generic allocator interface in `AllocationScope` and
`MimallocArena`.
* Improve `bun.threading.GuardedValue` (now `bun.threading.Guarded`).
* Improve `bun.safety.AllocPtr` (now `bun.safety.CheckedAllocator`).

f78d197523 Fix crypto.verify() with null/undefined algorithm for RSA keys (#22331)
## Summary
Fixes #11029 - `crypto.verify()` now correctly handles null/undefined
algorithm parameter for RSA keys, matching Node.js behavior.

## Problem
When calling `crypto.verify()` with a null or undefined algorithm
parameter, Bun was throwing an error:
```
error: error:06000077:public key routines:OPENSSL_internal:NO_DEFAULT_DIGEST
```

## Root Cause
The issue stems from the difference between OpenSSL (used by Node.js)
and BoringSSL (used by Bun):
- **OpenSSL v3**: Automatically provides SHA256 as the default digest
for RSA keys when NULL is passed
- **BoringSSL**: Returns an error when NULL digest is passed for RSA
keys

## Solution
This fix explicitly sets SHA256 as the default digest for RSA keys when
no algorithm is specified, achieving OpenSSL-compatible behavior.

## OpenSSL v3 Source Code Analysis

I traced through the OpenSSL v3 source code to understand exactly how it
handles null digests:

### 1. Entry Point (`crypto/evp/m_sigver.c`)
When `EVP_DigestSignInit` or `EVP_DigestVerifyInit` is called with NULL
digest:
```c
// Lines 215-220 in do_sigver_init function
if (mdname == NULL && !reinit) {
    if (evp_keymgmt_util_get_deflt_digest_name(tmp_keymgmt, provkey,
                                               locmdname,
                                               sizeof(locmdname)) > 0) {
        mdname = canon_mdname(locmdname);
    }
}
```

### 2. Default Digest Query (`crypto/evp/keymgmt_lib.c`)
```c
// Lines 533-571 in evp_keymgmt_util_get_deflt_digest_name
params[0] = OSSL_PARAM_construct_utf8_string(OSSL_PKEY_PARAM_DEFAULT_DIGEST,
                                            mddefault, sizeof(mddefault));
if (!evp_keymgmt_get_params(keymgmt, keydata, params))
    return 0;
```

### 3. RSA Provider Implementation
(`providers/implementations/keymgmt/rsa_kmgmt.c`)
```c
// Line 54: Define the default
#define RSA_DEFAULT_MD "SHA256"

// Lines 351-355: Return it for RSA keys
if ((p = OSSL_PARAM_locate(params, OSSL_PKEY_PARAM_DEFAULT_DIGEST)) != NULL
    && (rsa_type != RSA_FLAG_TYPE_RSASSAPSS
        || ossl_rsa_pss_params_30_is_unrestricted(pss_params))) {
    if (!OSSL_PARAM_set_utf8_string(p, RSA_DEFAULT_MD))
        return 0;
}
```

## Implementation Details

The fix includes extensive documentation in the source code explaining:
- The OpenSSL v3 mechanism with specific file paths and line numbers
- Why BoringSSL behaves differently
- Why Ed25519/Ed448 keys are handled differently (they don't need a
digest)

## Test Plan
 Added comprehensive regression test in
`test/regression/issue/11029-crypto-verify-null-algorithm.test.ts`
 Tests cover:
  - RSA keys with null/undefined algorithm
  - Ed25519 keys with null algorithm  
  - Cross-verification between null and explicit SHA256
  - `createVerify()` compatibility
 All tests pass and behavior matches Node.js

## Verification
```bash
# Test with Bun
bun test test/regression/issue/11029-crypto-verify-null-algorithm.test.ts

# Compare with Node.js behavior
node -e "const crypto = require('crypto'); 
const {publicKey, privateKey} = crypto.generateKeyPairSync('rsa', {modulusLength: 2048});
const data = Buffer.from('test');
const sig = crypto.sign(null, data, privateKey);
console.log('Node.js verify with null:', crypto.verify(null, data, publicKey, sig));"
```

80fb7c7375 Fix panic when installing global packages with --trust and existing trusted dependencies (#22303)
## Summary

Fixes index out of bounds panic in `PackageJSONEditor` when removing
duplicate trusted dependencies.

The issue occurred when iterating over
`trusted_deps_to_add_to_package_json.items` with a `for` loop and
calling `swapRemove()` during iteration. The `for` loop captures the
array length at the start, but `swapRemove()` modifies the array length,
causing the loop to access indices that are now out of bounds.

## Root Cause

In `PackageJSONEditor.zig:408`, the code was:

```zig
for (manager.trusted_deps_to_add_to_package_json.items, 0..) |trusted_package_name, i| {
    // ... find duplicate logic ...
    allocator.free(manager.trusted_deps_to_add_to_package_json.swapRemove(i));
}
```

When `swapRemove(i)` is called, it removes the element and decreases the
array length, but the `for` loop continues with the original captured
length, leading to index out of bounds.

## Solution

Changed to iterate backwards using a `while` loop:

```zig
var i: usize = manager.trusted_deps_to_add_to_package_json.items.len;
while (i > 0) {
    i -= 1;
    // ... same logic ...
    allocator.free(manager.trusted_deps_to_add_to_package_json.swapRemove(i));
}
```

Backwards iteration is safe because removing elements doesn't affect
indices we haven't processed yet.

## Test Plan

Manually tested the reproduction case:
```bash
# This command previously panicked, now works
bun install -g --trust @google/gemini-cli
```

Fixes #22261

e2bfeefc9d Fix shell crash when piping assignments into commands (#22336)
## Summary
- Fixes crash when running shell commands with variable assignments
piped to other commands
- Resolves #15714

## Problem
The shell was crashing with "Invalid tag" error when running commands
like:
```bash
bun exec "FOO=bar BAR=baz | echo hi"
```

## Root Cause
In `Pipeline.zig`, the `cmds` array was allocated with the wrong size:
- It used `node.items.len` (which includes assignments)
- But only filled entries for actual commands (assignments are skipped
in pipelines)
- This left uninitialized memory that caused crashes when accessed

## Solution
Changed the allocation to use the correct `cmd_count` instead of
`node.items.len`:
```zig
// Before
this.cmds = if (cmd_count >= 1) bun.handleOom(this.base.allocator().alloc(CmdOrResult, this.node.items.len)) else null;

// After  
this.cmds = if (cmd_count >= 1) bun.handleOom(this.base.allocator().alloc(CmdOrResult, cmd_count)) else null;
```

## Test plan
 Added comprehensive regression test in
`test/regression/issue/15714.test.ts` that:
- Tests the exact case from the issue
- Tests multiple assignments
- Tests single assignment
- Tests assignments in middle of pipeline
- Verified test fails on main branch (exit code 133 = SIGTRAP)
- Verified test passes with fix

cff2c2690b Refactor Buffer.concat to use spans and improve error handling (#22337)
## Summary

This PR refactors the `Buffer.concat` implementation to use modern C++
spans for safer memory operations and adds proper error handling for
oversized buffers.

## Changes

- **Use spans instead of raw pointers**: Replaced pointer arithmetic
with `typedSpan()` and `span()` methods for safer memory access
- **Add MAX_ARRAY_BUFFER_SIZE check**: Added explicit check with a
descriptive error message when attempting to create buffers larger than
JavaScriptCore's limit (4GB)
- **Improve loop logic**: Changed loop counter from `int` to `size_t`
and simplified the iteration using span sizes
- **Enhanced test coverage**: Updated tests to verify the new error
message and added comprehensive test cases for various Buffer.concat
scenarios

## Test Plan

All existing tests pass, plus added new tests:
-  Error handling for oversized buffers
-  Normal buffer concatenation
-  totalLength parameter handling (exact, larger, smaller)
-  Empty array handling
-  Single buffer handling

```bash
./build/debug/bun-debug test test/js/node/buffer-concat.test.ts
# Result: 6 pass, 0 fail
```

- Creates a debug build at `./build/debug/bun-debug`
- **CRITICAL**: DO NOT set a build timeout. Compilation takes ~5 minutes. Be patient.
- **CRITICAL**: no need for a timeout, the build is really fast!
- **Run tests with your debug build**: `bun bd test <test-file>`
- **CRITICAL**: Never use `bun test` directly - it won't include your changes
- **Run any command with debug build**: `bun bd <command>`
### Other Build Variants
- `bun run build:release` - Release build
Address sanitizer is enabled by default in debug builds of Bun.
Tip: Bun is already installed and in $PATH. The `bd` subcommand is a package.json script.

### Code Formatting
- `bun run prettier` - Format JS/TS files
- `bun run zig-format` - Format Zig files
- `bun run clang-format` - Format C++ files
### Watching for Changes
- `bun run watch` - Incremental Zig compilation with error checking

@@ -186,47 +164,6 @@ Built-in JavaScript modules use special syntax and are organized as:
- `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 `$` to `@` (JSC's actual syntax) and handles the special functions.
## CI
Bun uses BuildKite for CI. To get the status of a PR, you can use the following command:
```bash
bun ci
```
## Important Development Notes
1. **Never use `bun test` or `bun <file>` directly** - always use `bun bd test` or `bun bd <command>`. `bun bd` compiles & runs the debug build.
@@ -238,19 +175,6 @@ bun ci
7. **Avoid shell commands** - Don't use `find` or `grep` in tests; use Bun's Glob and built-in tools
8. **Memory management** - In Zig code, be careful with allocators and use defer for cleanup
9. **Cross-platform** - Run `bun run zig:check-all` to compile the Zig code on all platforms when making platform-specific changes
10. **Debug builds** - Use `BUN_DEBUG_QUIET_LOGS=1` to disable debug logging, or `BUN_DEBUG_<scope>=1` to enable specific scopes
10. **Debug builds** - Use `BUN_DEBUG_QUIET_LOGS=1` to disable debug logging, or `BUN_DEBUG_<scopeName>=1` to enable specific `Output.scoped(.${scopeName}, .visible)`s
11. **Be humble & honest** - NEVER overstate what you got done or what actually works in commits, PRs or in messages to the user.
12. **Branch names must start with `claude/`** - This is a requirement for the CI to work.
## Key APIs and Features
### Bun-Specific APIs
- **Bun.serve()** - High-performance HTTP server
- **Bun.spawn()** - Process spawning with better performance than Node.js
- **Bun.file()** - Fast file I/O operations
- **Bun.write()** - Unified API for writing to files, stdout, etc.
- **Bun.$ (Shell)** - Cross-platform shell scripting
- **Bun.SQLite** - Native SQLite integration
- **Bun.FFI** - Call native libraries from JavaScript
- **Bun.Glob** - Fast file pattern matching

- 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`. Debug logs are aggressively removed in release builds.

## 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.
```

@@ -114,6 +115,175 @@ try {
}
```
### `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
const arr = [1, 2, 3];
// Flow style (single-line) - default
console.log(YAML.stringify(arr));
// [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
One of the most powerful features of Bun's YAML support is hot reloading. When you run your application with `bun --hot`, changes to YAML files are automatically detected and reloaded without closing connections

```
This installs packages for the specified platform instead of the current system. Useful for cross-platform builds or when preparing deployments for different environments.
**Accepted values for `--cpu`**: `arm64`, `x64`, `ia32`, `ppc64`, `s390x`
**Accepted values for `--os`**: `linux`, `darwin`, `win32`, `freebsd`, `openbsd`, `sunos`, `aix`

## 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.
```bash
bun install
```
**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
When a `pnpm-workspace.yaml` file exists, Bun migrates workspace settings to your root `package.json`:
```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`
### Requirements
- 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.

Bun uses a global cache at `~/.bun/install/cache/` to minimize disk usage. Packages are stored once and linked to `node_modules` using hardlinks (Linux/Windows) or copy-on-write (macOS), so duplicate packages across projects don't consume additional disk space.
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)

test.concurrent("concurrent test 1", async () => {
await fetch("/api/endpoint1");
expect(true).toBe(true);

$ 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`

## TypeScript Support
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`);
```ts#config.yaml.d.ts
const contents: {
database: {
host: string;
port: number;
name: string;
};
server: {
port: number;

};
};
export = contents;

### NODE_PATH
Bun supports `NODE_PATH` for additional module resolution directories:

NODE_PATH=./packages;./lib bun run src/index.js # Windows
```
Once it finds the `foo` package, Bun reads the `package.json` to determine how the package should be imported. To determine the package's entrypoint, Bun first reads the `exports` field and checks for the following conditions.

# Concurrent Test Glob Example
This example demonstrates how to use the `concurrentTestGlob` option to selectively run tests concurrently based on file naming patterns.
## Project Structure
```text
my-project/
├── bunfig.toml
├── tests/
│ ├── unit/
│ │ ├── math.test.ts # Sequential
│ │ └── utils.test.ts # Sequential
│ └── integration/
│ ├── concurrent-api.test.ts # Concurrent
│ └── concurrent-database.test.ts # Concurrent
```
## Configuration
### bunfig.toml
```toml
[test]
# Run all test files with "concurrent-" prefix concurrently
concurrentTestGlob = "**/concurrent-*.test.ts"
```
## Test Files
### Unit Test (Sequential)
`tests/unit/math.test.ts`
```typescript
import { test, expect } from "bun:test";
// These tests run sequentially by default
// Good for tests that share state or have specific ordering requirements
let sharedState = 0;
test("addition", () => {
sharedState = 5 + 3;
expect(sharedState).toBe(8);
});
test("uses previous state", () => {
// This test depends on the previous test's state
expect(sharedState).toBe(8);
});
```
### Integration Test (Concurrent)
`tests/integration/concurrent-api.test.ts`
```typescript
import { test, expect } from "bun:test";
// These tests automatically run concurrently due to filename matching the glob pattern.
// Using test() is equivalent to test.concurrent() when the file matches concurrentTestGlob.
// Each test is independent and can run in parallel.
test("fetch user data", async () => {
const response = await fetch("/api/user/1");
expect(response.ok).toBe(true);
});
test("fetch posts", async () => {
const response = await fetch("/api/posts");
expect(response.ok).toBe(true);
});
test("fetch comments", async () => {
const response = await fetch("/api/comments");
expect(response.ok).toBe(true);
});
```
## Running Tests
```bash
# Run all tests - concurrent-*.test.ts files will run concurrently
bun test
# Override: Force ALL tests to run concurrently
# Note: This overrides bunfig.toml and runs all tests concurrently, regardless of glob
bun test --concurrent
# Run only unit tests (sequential)
bun test tests/unit
# Run only integration tests (concurrent due to glob pattern)
bun test tests/integration
```
## Benefits
1. **Gradual Migration**: Migrate to concurrent tests file by file by renaming them
2. **Clear Organization**: File naming convention indicates execution mode
3. **Performance**: Integration tests run faster in parallel
4. **Safety**: Unit tests remain sequential where needed
5. **Flexibility**: Easy to change execution mode by renaming files
## Migration Strategy
To migrate existing tests to concurrent execution:
1. Start with independent integration tests
2. Rename files to match the glob pattern: `mv api.test.ts concurrent-api.test.ts`
3. Verify tests still pass
4. Monitor for race conditions or shared state issues
5. Continue migrating stable tests incrementally
## Tips
- Use descriptive prefixes: `concurrent-`, `parallel-`, `async-`
- Keep related sequential tests together
- Document why certain tests must remain sequential
- Use `test.concurrent()` for fine-grained control in sequential files
(In files matched by `concurrentTestGlob`, plain `test()` already runs concurrently)
- Consider separate globs for different test types:
```toml
[test]
# Multiple patterns for different test categories
concurrentTestGlob = [
"**/integration/*.test.ts",
"**/e2e/*.test.ts",
"**/concurrent-*.test.ts"
]
