## 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.

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
...
```

## 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

## 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.

### 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`.

## 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 }}`

## 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.

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.

## 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

## 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.

### 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.

## Summary
When a snapshot is created in CI without `--update-snapshots`, the error
message now displays the received value that was attempting to be
snapshotted. This helps developers understand what value triggered the
error.
## Changes
- Modified the `SnapshotCreationNotAllowedInCI` error message in
`src/bun.js/test/expect.zig` to include the received value using the
same formatting pattern as other expect error messages
## Before
```
Snapshot creation is not allowed in CI environments unless --update-snapshots is used
If this is not a CI environment, set the environment variable CI=false to force allow.
```
## After
```
Snapshot creation is not allowed in CI environments unless --update-snapshots is used
If this is not a CI environment, set the environment variable CI=false to force allow.
Received: <formatted value>
