### What does this PR do?
This PR adds `Bun.YAML.stringify`. The stringifier will double quote
strings only when necessary (looks for keywords, numbers, or containing
non-printable or escaped characters). Anchors and aliases are detected
by object equality, and anchor name is chosen from property name, array
item, or the root collection.
```js
import { YAML } from "bun"
YAML.stringify(null) // null
YAML.stringify("hello YAML"); // "hello YAML"
YAML.stringify("123.456"); // "\"123.456\""
// anchors and aliases
const userInfo = { name: "bun" };
const obj = { user1: { userInfo }, user2: { userInfo } };
YAML.stringify(obj, null, 2);
// # output
// user1:
// userInfo:
// &userInfo
// name: bun
// user2:
// userInfo:
// *userInfo
// will handle cycles
const obj = {};
obj.cycle = obj;
YAML.stringify(obj, null, 2);
// # output
// &root
// cycle:
// *root
// default no space
const obj = { one: { two: "three" } };
YAML.stringify(obj);
// # output
// {one: {two: three}}
```

## Summary
Fixes#20596
This PR resolves the "Unable to deserialize data" error when using
`structuredClone()` with nested objects containing `Blob` or `File`
objects, and ensures that `File` objects preserve their `name` property
during structured clone operations.
## Problem
### Issue 1: "Unable to deserialize data" Error
When cloning nested structures containing Blob/File objects,
`structuredClone()` would throw:
```
TypeError: Unable to deserialize data.
```
**Root Cause**: The `StructuredCloneableDeserialize::fromTagDeserialize`
function wasn't advancing the pointer (`m_ptr`) after deserializing
Blob/File objects. This caused subsequent property reads in nested
scenarios to start from the wrong position in the serialized data.
**Affected scenarios**:
- ✅ `structuredClone(blob)` - worked fine (direct cloning)
- ❌ `structuredClone({blob})` - threw error (nested cloning)
- ❌ `structuredClone([blob])` - threw error (array cloning)
- ❌ `structuredClone({data: {files: [file]}})` - threw error (complex
nesting)
### Issue 2: File Name Property Lost
Even when File cloning worked, the `name` property was not preserved:
```javascript
const file = new File(["content"], "test.txt");
const cloned = structuredClone(file);
console.log(cloned.name); // undefined (should be "test.txt")
```
**Root Cause**: The structured clone serialization only handled basic
Blob properties but didn't serialize/deserialize the File-specific
`name` property.
## Solution
### Part 1: Fix Pointer Advancement
**Modified Code Generation** (`src/codegen/generate-classes.ts`):
- Changed `fromTagDeserialize` function signature from `const uint8_t*`
to `const uint8_t*&` (pointer reference)
- Updated implementation to cast pointer correctly: `(uint8_t**)&ptr`
- Fixed both C++ extern declarations and Zig wrapper signatures
**Updated Zig Functions**:
- **Blob.zig**: Modified `onStructuredCloneDeserialize` to take `ptr:
*[*]u8` and advance it by `buffer_stream.pos`
- **BlockList.zig**: Applied same fix for consistency across all
structured clone types
### Part 2: Add File Name Preservation
**Enhanced Serialization Format**:
- Incremented serialization version from 2 to 3 to support File name
serialization
- Added File name serialization using `getNameString()` to handle all
name storage scenarios
- Added proper deserialization with `bun.String.cloneUTF8()` for UTF-8
string creation
- Maintained backwards compatibility with existing serialization
versions
## Testing
Created comprehensive test suite
(`test/js/web/structured-clone-blob-file.test.ts`) with **24 tests**
covering:
### Core Functionality
- Direct Blob/File cloning (6 tests)
- Nested Blob/File in objects and arrays (8 tests)
- Mixed Blob/File scenarios (4 tests)
### Edge Cases
- Blob/File with empty data (6 tests)
- File with empty data and empty name (2 tests)
### Regression Tests
- Original issue 20596 reproduction cases (3 tests)
**Results**: All **24/24 tests pass** (up from 5/18 before the fix)
## Key Changes
1. **src/codegen/generate-classes.ts**:
- Updated `fromTagDeserialize` signature and implementation
- Fixed C++ extern declarations for pointer references
2. **src/bun.js/webcore/Blob.zig**:
- Enhanced pointer advancement in deserialization
- Added File name serialization/deserialization
- Incremented serialization version with backwards compatibility
3. **src/bun.js/node/net/BlockList.zig**:
- Applied consistent pointer advancement fix
4. **test/js/web/structured-clone-blob-file.test.ts**:
- Comprehensive test suite covering all scenarios and edge cases
## Backwards Compatibility
- ✅ Existing structured clone functionality unchanged
- ✅ All other structured clone tests continue to pass (118/118 worker
tests pass)
- ✅ Serialization version 3 supports versions 1-2 with proper fallback
- ✅ No breaking changes to public APIs
## Performance Impact
- ✅ No performance regression in existing functionality
- ✅ Minimal overhead for File name serialization (only when
`is_jsdom_file` is true)
- ✅ Efficient pointer arithmetic for advancement

### What does this PR do?
The async_hooks warning is mostly just noise. There's no action you can
take. And React is now using this to track the error.stack of every
single promise with a no-op if it's not in use, so let's be silent about
this by default instead of noisy.

### What does this PR do?
Originally, we attempted to avoid the "dual package hazard" right before
we enqueue a parse task, but that code gets called in a
non-deterministic order. This meant that some of your modules would use
the right variant and some of them would not.
We have to instead do that in a separate pass, after all the files are
parsed.
The thing to watch out for with this PR is how it impacts the dev
server.

## Summary
Fixes a crash with `panic: attempt to use null value` in
`html_rewriter.zig:1190` when accessing TextChunk properties after
HTMLRewriter cleanup.
The crash occurred in the `lastInTextNode` and `removed` methods when
they tried to dereference a null `text_chunk` pointer using
`this.text_chunk.?` without proper null checks.
## Root Cause
The TextChunk methods `removed()` and `lastInTextNode()` were missing
null checks that other methods like `getText()` and `remove()` already
had. When TextChunk objects are accessed after the HTMLRewriter
transformation completes and internal cleanup occurs, the `text_chunk`
pointer becomes null, causing a panic.
## Changes
- **src/bun.js/api/html_rewriter.zig**:
- Add null check to `removed()` method - returns `false` when
`text_chunk` is null
- Add null check to `lastInTextNode()` method - returns `false` when
`text_chunk` is null
- **test/regression/issue/text-chunk-null-access.test.ts**:
- Add regression test that reproduces the original crash scenario
- Test verifies that accessing TextChunk properties after cleanup
returns sensible defaults instead of crashing
## Crash Reproduction
The regression test successfully reproduces the crash:
- **Regular `bun test`**: ❌ CRASHES with `panic: attempt to use null
value`
- **With fix `bun bd test`**: ✅ PASSES
## Test Plan
- [x] Existing HTMLRewriter tests still pass
- [x] New regression test passes with the fix
- [x] New regression test crashes without the fix (confirmed on regular
bun)
- [x] Both `removed` and `lastInTextNode` now return sensible defaults
(`false`) when called on cleaned up TextChunk objects

in JS, `new TextDecoder("latin1").decode(...)` uses cp1252. In python,
latin1 is half-width utf-16. In our code, latin1 typically refers to
half-width utf-16 because JavaScriptCore uses that for most strings, but
sometimes it refers to cp1252. Rename the cp1252 functions to be called
cp1252
Also fixes an issue where Buffer.from with utf-16le would sometimes
output the wrong value:
```js
$> bun -p "Buffer.from('\x80', 'utf-16le')"
<Buffer ac 20>
$> node -p "Buffer.from('\x80', 'utf-16le')"
<Buffer 80 00>
$> bun-debug -p "Buffer.from('\x80', 'utf-16le')"
<Buffer 80 00>
```
## Summary
- Fixed allocator threading violation when `BUN_INSPECT_CONNECT_TO` is
set
- Created thread-local `env_loader` with proper allocator isolation in
debugger thread
- Added regression test to verify the fix works correctly
## Problem
When `BUN_INSPECT_CONNECT_TO` environment variable is set, Bun creates a
debugger thread that spawns its own `VirtualMachine` instance.
Previously, this VM would fall back to the global `DotEnv.instance`
which was created with the main thread's allocator, causing threading
violations when the debugger thread accessed environment files via
`--env-file` or other env loading operations.
## Solution
Modified `startJSDebuggerThread` in `src/bun.js/Debugger.zig` to:
1. Create a thread-local `DotEnv.Map` and `DotEnv.Loader` using the
debugger thread's allocator
2. Pass this thread-local `env_loader` to `VirtualMachine.init()` to
ensure proper allocator isolation
3. Prevent sharing of allocators across threads
## Test plan
- [x] Added regression test in
`test/regression/issue/test_env_loader_threading.test.ts`
- [x] Verified basic Bun functionality still works
- [x] Test passes with both normal execution and with
`BUN_INSPECT_CONNECT_TO` set

## Summary
Fixes an issue where compiled standalone binaries included an extra
executable name argument in `process.argv`, breaking code that uses
`node:util.parseArgs()` with `process.argv.slice(2)`.
## Problem
When running a compiled binary, `process.argv` incorrectly included the
executable name as a third argument:
```bash
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app", "./my-app"] # BUG
```
This caused `parseArgs()` to fail with "Unexpected argument" errors,
breaking previously valid code.
## Solution
Fixed the `offset_for_passthrough` calculation in `cli.zig` to always
skip the executable name for standalone binaries, ensuring
`process.argv` only contains the runtime name and script path:
```bash
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app"] # FIXED
```
## Test plan
- [x] Added regression test in `test/regression/issue/22157.test.ts`
- [x] Verified existing exec-argv functionality still works correctly
- [x] Manual testing confirms the fix resolves the parseArgs issue

## Summary
Fixes a bug in the internal `bun.spawnSync` implementation where
stderr's poll file descriptor was incorrectly set to stdout's fd when
polling both streams.
## The Bug
In `/src/bun.js/api/bun/process.zig` line 2204, when setting up the poll
file descriptor array for stderr, the code incorrectly used
`out_fds_to_wait_for[0]` (stdout) instead of `out_fds_to_wait_for[1]`
(stderr).
This meant:
- stderr's fd was never actually polled
- stdout's fd was polled twice
- Could cause stderr data to be lost or incomplete
- Could potentially cause hangs when reading from stderr
## Impact
This bug only affects Bun's internal CLI commands that use
`bun.spawnSync` with both stdout and stderr piped (like `bun create`,
`bun upgrade`, etc.). The JavaScript `spawnSync` API uses a different
code path and is not affected.
## The Fix
Changed line 2204 from:
```zig
poll_fds[poll_fds.len - 1].fd = @intCast(out_fds_to_wait_for[0].cast());
```
to:
```zig
poll_fds[poll_fds.len - 1].fd = @intCast(out_fds_to_wait_for[1].cast());
```

## Summary
Fixes an issue where `--compile-exec-argv` options were incorrectly
appearing in `process.argv` when no user arguments were provided to a
compiled standalone binary.
## Problem
When building a standalone binary with `--compile-exec-argv`, the exec
argv options would leak into `process.argv` when running the binary
without any user arguments:
```bash
# Build with exec argv
bun build --compile-exec-argv="--user-agent=hello" --compile ./a.js
# Run without arguments - BEFORE fix
./a
# Output showed --user-agent=hello in both execArgv AND argv (incorrect)
{
execArgv: [ "--user-agent=hello" ],
argv: [ "bun", "/$bunfs/root/a", "--user-agent=hello" ], # <- BUG: exec argv leaked here
}
# Expected behavior (matches runtime):
bun --user-agent=hello a.js
{
execArgv: [ "--user-agent=hello" ],
argv: [ "/path/to/bun", "/path/to/a.js" ], # <- No exec argv in process.argv
}
```
## Solution
The issue was in the offset calculation for determining which arguments
to pass through to the JavaScript runtime. The offset was being
calculated before modifying the argv array with exec argv options,
causing it to be incorrect when the original argv only contained the
executable name.
The fix ensures that:
- `process.execArgv` correctly contains the compile-exec-argv options
- `process.argv` only contains the executable, script path, and user
arguments
- exec argv options never leak into `process.argv`
## Test plan
Added comprehensive tests to verify:
1. Exec argv options don't leak into process.argv when no user arguments
are provided
2. User arguments are properly passed through when exec argv is present
3. Existing behavior continues to work correctly
All tests pass:
```
bun test compile-argv.test.ts
✓ 3 tests pass
```

This PR adds `Bun.secrets`, a new API for securely storing and
retrieving credentials using the operating system's native credential
storage locally. This helps developers avoid storing sensitive data in
plaintext config files.
```javascript
// Store a GitHub token securely
await Bun.secrets.set({
service: "my-cli-tool",
name: "github-token",
value: "ghp_xxxxxxxxxxxxxxxxxxxx"
});
// Retrieve it when needed
const token = await Bun.secrets.get({
service: "my-cli-tool",
name: "github-token"
});
// Use with fallback to environment variable
const apiKey = await Bun.secrets.get({
service: "my-app",
name: "api-key"
}) || process.env.API_KEY;
```
Marking this as a draft because Linux and Windows have not been manually
tested yet. This API is only really meant for local development usecases
right now, but it would be nice if in the future to support adapters for
production or CI usecases.
### Core API
- `Bun.secrets.get({ service, name })` - Retrieve a stored credential
- `Bun.secrets.set({ service, name, value })` - Store or update a
credential
- `Bun.secrets.delete({ service, name })` - Delete a stored credential
### Platform Support
- **macOS**: Uses Keychain Services via Security.framework
- **Linux**: Uses libsecret (works with GNOME Keyring, KWallet, etc.)
- **Windows**: Uses Windows Credential Manager via advapi32.dll
### Implementation Highlights
- Non-blocking - all operations run on the threadpool
- Dynamic loading - no hard dependencies on system libraries
- Sensitive data is zeroed after use
- Consistent API across all platforms
## Use Cases
This API is particularly useful for:
- CLI tools that need to store authentication tokens
- Development tools that manage API keys
- Any tool that currently stores credentials in `~/.npmrc`,
`~/.aws/credentials` or in environment variables that're globally loaded
## Testing
Comprehensive test suite included with coverage for:
- Basic CRUD operations
- Empty strings and special characters
- Unicode support
- Concurrent operations
- Error handling
All tests pass on macOS. Linux and Windows implementations are complete
but would benefit from additional platform testing.
## Documentation
- Complete API documentation in `docs/api/secrets.md`
- TypeScript definitions with detailed JSDoc comments and examples

Also YAML imports work just like JSON and TOML imports
```js
import pkg from "./package.yaml"
console.log({ pkg }); // { pkg: { name: "pkg", version: "1.1.1" } }
```
### How did you verify your code works?
Added some tests for YAML imports and parsed values.

* `IncrementalGraph(.client).File` packs its fields in a specific way to
save space, but it makes the struct hard to use and error-prone (e.g.,
untagged unions with tags stored in a separate `flags` struct). This PR
changes `File` to have a human-readable layout, but adds methods to
convert it to and from `File.Packed`, a packed version with the same
space efficiency as before.
* Reduce the need to pass the dev allocator to functions (e.g.,
`deinit`) by storing it as a struct field via the new `DevAllocator`
type. This type has no overhead in release builds, or when
`AllocationScope` is disabled.
* Use owned pointers in `PackedMap`.
* Use `bun.ptr.Shared` for `PackedMap` instead of the old
`bun.ptr.RefPtr`.
* Add `bun.ptr.ScopedOwned`, which is like `bun.ptr.Owned`, but can
store an `AllocationScope`. No overhead in release builds or when
`AllocationScope` is disabled.
* Reduce redundant allocators in `BundleV2`.
* Add owned pointer conversions to `MutableString`.
* Make `AllocationScope` behave like a pointer, so it can be moved
without invalidating allocations. This eliminates the need for
self-references.
* Change memory cost algorithm so it doesn't rely on “dedupe bits”.
These bits used to take advantage of padding but there is now no padding
in `PackedMap`.
* Replace `VoidFieldTypes` with `useAllFields`; this eliminates the need

## Summary
Fixes an assertion failure that occurred when `server.stop()` was called
while HTTP requests were still in flight.
## Root Cause
The issue was in `jsValueAssertAlive()` at
`src/bun.js/api/server.zig:627`, which had an assertion requiring
`server.listener != null`. However, `server.stop()` immediately sets
`listener` to null, causing assertion failures when pending requests
triggered callbacks that accessed the server's JavaScript value.
## Solution
Converted the server's `js_value` from `jsc.Strong.Optional` to
`jsc.JSRef` for safer lifecycle management:
- **On `stop()`**: Downgrade from strong to weak reference instead of
calling `deinit()`
- **In `finalize()`**: Properly call `deinit()` on the JSRef
- **Remove problematic assertion**: JSRef allows safe access to JS value
via weak reference even after stop
## Benefits
- ✅ No more assertion failures when stopping servers with pending
requests
- ✅ In-flight requests can still access the server JS object safely
- ✅ JS object can be garbage collected when appropriate
- ✅ Maintains backward compatibility - no external API changes
## Test plan
- [x] Reproduces the original assertion failure
- [x] Verifies the fix resolves the issue
- [x] Adds regression test to prevent future occurrences
- [x] Confirms normal server functionality still works
The fix includes a comprehensive regression test at
`test/regression/issue/server-stop-with-pending-requests.test.ts`.

## Summary
- Implement `Symbol.asyncDispose` for the `Worker` class in
`worker_threads` module
- Enables automatic resource cleanup with `await using` syntax
- Calls `await this.terminate()` to properly shut down workers when they
go out of scope
## Implementation Details
The implementation adds a simple async method to the Worker class:
```typescript
async [Symbol.asyncDispose]() {
await this.terminate();
}
```
This allows workers to be used with the new `await using` syntax for
automatic cleanup:
```javascript
{
await using worker = new Worker('./worker.js');
// worker automatically terminates when leaving this scope
}
```
## Test Plan
- [x] Added comprehensive tests for `Symbol.asyncDispose` functionality
- [x] Tests verify the method exists and returns undefined
- [x] Tests verify `await using` syntax works correctly for automatic
worker cleanup
- [x] All new tests pass
- [x] Existing worker_threads functionality remains intact

Followup to #22049: I'm pretty sure “platform-specific padding” on
Windows is a hallucination. I think this is due to ReleaseSafe adding
tags to untagged unions.
(For internal tracking: fixes STAB-1057)
### What does this PR do?
Support the following:
```javascript
const nom = await sql`SELECT name FROM food WHERE category IN ${sql(['bun', 'baozi', 'xiaolongbao'])}`;
```
Previously, only e.g., `sql([1, 2, 3])` was supported.
To be honest I'm not sure what the semantics of SQLHelper *ought* to be.
I'm pretty sure objects ought to be auto-inferred. I'm not sure about
arrays, but given the rest of the code in `SQLHelper` trying to read the
tea leaves on stringified numeric keys I figured someone cared about
this use case. I don't know about other types, but I'm pretty sure that
`Object.keys("bun") === [0, 1, 2]` is an oversight and unintended.
(Incidentally, the reason numbers previously worked is because
`Object.keys(4) === []`). I decided that all non-objects and non-arrays
should be treated as not having auto-inferred columns.
Fixes#18637
### How did you verify your code works?
I wrote a test, but was unable to run it (or any other tests in this
file) locally due to Docker struggles. I sure hope it works!
### What does this PR do?
This PR fixes https://github.com/oven-sh/bun/issues/19131.
I am not 100% certain that this fix is correct as I am still nebulous
regarding some decisions I've made in this PR. I'll try to provide my
reasoning and would love to be proven wrong:
#### Re-authentication
- The `is_authenticated` flag needs to be reset to false. When the
lifecycle reaches a point of attempting to connect, it sends out a
`HELLO 3`, and receives a response. `handleResponse()` is fired and does
not correctly handle it because there is a guard at the top of the
function:
```zig
if (!this.flags.is_authenticated) {
this.handleHelloResponse(value);
// We've handled the HELLO response without consuming anything from the command queue
return;
}
```
Rather, it treats this packet as a regular data packet and complains
that it doesn't have a promise to associate it to. By resetting the
`is_authenticated` flag to false, we guarantee that we handle the `HELLO
3` packet as an authentication packet.
It also seems to make semantic sense since dropping a connection implies
you dropped authentication.
#### Retry Attempts
I've deleted the `retry_attempts = 0` in `reconnect()` because I noticed
that we would never actually re-attempt to reconnect after the first
attempt. Specifically, I was expecting `valkey.zig:459` to potentially
fire multiple times, but it only ever fired once. Removing this reset to
zero caused successful reattempts (in my case 3 of them).
```zig
debug("reconnect in {d}ms (attempt {d}/{d})", .{ delay_ms, this.retry_attempts, this.max_retries });
```
I'm still iffy on whether this is necessary, but I think it makes sense.
```zig
this.client.retry_attempts = 0
```
### How did you verify your code works?
I have added a small unit test. I have compared mainline `bun`, which
fails that test, to this fix, which passes the test.
