b87ac4a781 Update ci_info with more CI detection (#23708)
Fixes ENG-21481

Updates ci_info to include more CIs. It makes it codegen the ci
detection based on the json from the ci-info package. Also it supports
setting CI=true to force ci detected.

05d0475c6c Update to zig 0.15.2 (#24204)
Fixes ENG-21287

Build times, from `bun run build && echo '//' >> src/main.zig && time
bun run build`

|Platform|0.14.1|0.15.2|Speedup|
|-|-|-|-|
|macos debug asan|126.90s|106.27s|1.19x|
|macos debug noasan|60.62s|50.85s|1.19x|
|linux debug asan|292.77s|241.45s|1.21x|
|linux debug noasan|146.58s|130.94s|1.12x|
|linux debug use_llvm=false|n/a|78.27s|1.87x|
|windows debug asan|177.13s|142.55s|1.24x|

Runtime performance:

- next build memory usage may have gone up by 5%. Otherwise seems the
same. Some code with writers may have gotten slower, especially one
instance of a counting writer and a few instances of unbuffered writers
that now have vtable overhead.
- File size reduced by 800kb (from 100.2mb to 99.4mb)

Improvements:

- `@export` hack is no longer needed for watch
- native x86_64 backend for linux builds faster. to use it, set use_llvm
false and no_link_obj false. also set `ASAN_OPTIONS=detect_leaks=0`
otherwise it will spam the output with tens of thousands of lines of
debug info errors. may need to use the zig lldb fork for debugging.
- zig test-obj, which we will be able to use for zig unit tests

Still an issue:

- false 'dependency loop' errors remain in watch mode
- watch mode crashes observed

Follow-up:

- [ ] search `comptime Writer: type` and `comptime W: type` and remove
- [ ] remove format_mode in our zig fork
- [ ] remove deprecated.zig autoFormatLabelFallback
- [ ] remove deprecated.zig autoFormatLabel
- [ ] remove deprecated.BufferedWriter and BufferedReader
- [ ] remove override_no_export_cpp_apis as it is no longer needed
- [ ] css Parser(W) -> Parser, and remove all the comptime writer: type
params
- [ ] remove deprecated writer fully

f65e280521 Add Nix flake for development environment (#23406)
Provides a Nix flake as an alternative to `scripts/bootstrap.sh` for
setting up the Bun development environment.

## What's included:

- **flake.nix**: Full development environment with all dependencies from
bootstrap.sh
  - LLVM 19, CMake 3.30+, Node.js 24, Rust, Go
  - Build tools: ninja, ccache, pkg-config, make
  - Chromium dependencies for Puppeteer testing
  - gdb for core dump debugging

- **shell.nix**: Simple wrapper for `nix-shell` usage

- **cmake/CompilerFlags.cmake**: Nix compatibility fixes
  - Disable zstd debug compression (Nix's LLVM not built with zstd)
  - Set _FORTIFY_SOURCE=0 for -O0 debug builds
  - Downgrade _FORTIFY_SOURCE warning to not error

## Usage:

```bash
nix-shell
export CMAKE_SYSTEM_PROCESSOR=$(uname -m)
bun bd
```

## Verified working:
 Successfully compiles Bun debug build
 Binary tested: `./build/debug/bun-debug --version` → 1.2.24-debug
 All dependencies from bootstrap.sh included

## Advantages:
- Fully isolated (no sudo required)
- 100% reproducible dependency versions  
- Fast setup with binary caching

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`.

STAB-1324)

# 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

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>`.

58782ceef2 Fix bun_dependency_versions.h regenerating on every CMake run (#22985)
## Summary
- Fixes unnecessary regeneration of `bun_dependency_versions.h` on every
CMake run
- Only writes the header file when content actually changes

## Test plan
Tested locally by running CMake configuration multiple times:
1. First run generates the file (shows "Updated dependency versions
header")
2. Subsequent runs skip writing (shows "Dependency versions header
unchanged")
3. File modification timestamp remains unchanged when content is the
same
4. File is properly regenerated when deleted or when content changes

8614b98f6b Disable glibcxx assertions in WebKit release non-asan builds (#22647)
### 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
 ```

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",
  "libarchive": "898dc8319355b7e985f68a9819f182aaed61b53a",
  "mimalloc": "4c283af60cdae205df5a872530c77e2a6a307d43",
  "webkit": "0ddf6f47af0a9782a354f61e06d7f83d097d9f84",
  "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
- `build/debug/bun_dependency_versions_debug.txt` - Human-readable
version list

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

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`).

48ebc15e63 Implement RFC 6455 compliant WebSocket subprotocol handling (#22323)
## Summary

- Implements proper WebSocket subprotocol negotiation per RFC 6455 and
WHATWG standards
- Adds HeaderValueIterator utility for parsing comma-separated header
values
- Fixes WebSocket client to correctly validate server subprotocol
responses
- Sets WebSocket.protocol property to negotiated subprotocol per WHATWG
spec
- Includes comprehensive test coverage for all subprotocol scenarios

## Changes

**Core Implementation:**
- Add `HeaderValueIterator` utility for parsing comma-separated HTTP
header values
- Replace hash-based protocol matching with proper string set comparison
- Implement WHATWG compliant protocol property setting on successful
negotiation

**WebSocket Client (`WebSocketUpgradeClient.zig`):**
- Parse client subprotocols into StringSet using HeaderValueIterator
- Validate server response against requested protocols
- Set protocol property when server selects a matching subprotocol
- Allow connections when server omits Sec-WebSocket-Protocol header (per
spec)
- Reject connections when server sends unknown or empty subprotocol
values

**C++ Bindings:**
- Add `setProtocol` method to WebSocket class for updating protocol
property
- Export C binding for Zig integration

## Test Plan

Comprehensive test coverage for all subprotocol scenarios:
-  Server omits Sec-WebSocket-Protocol header (connection allowed,
protocol="")
-  Server sends empty Sec-WebSocket-Protocol header (connection
rejected)
-  Server selects valid subprotocol from multiple client options
(protocol set correctly)
-  Server responds with unknown subprotocol (connection rejected with
code 1002)
-  Validates CloseEvent objects don't trigger [Circular] console bugs

All tests use proper WebSocket handshake implementation and validate
both client and server behavior per RFC 6455 requirements.

## Issues Fixed

Fixes #10459 - WebSocket client does not retrieve the protocol sent by
the server
Fixes #10672 - `obs-websocket-js` is not compatible with Bun  
Fixes #17707 - Incompatibility with NodeJS when using obs-websocket-js
library
Fixes #19785 - Mismatch client protocol when connecting with multiple
Sec-WebSocket-Protocol

This enables obs-websocket-js and other libraries that rely on proper
RFC 6455 subprotocol negotiation to work correctly with Bun.

fcaff77ed7 Implement Bun.YAML.stringify (#22183)
### 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);

## Summary by CodeRabbit

- New Features
- Added YAML.stringify to the YAML API, producing YAML from JavaScript
values with quoting, anchors, and indentation support.

- Improvements
- YAML.parse now accepts a wider range of inputs, including Buffer,
ArrayBuffer, TypedArrays, DataView, Blob/File, and SharedArrayBuffer,
with better error propagation and stack protection.

- Tests
- Extensive new tests for YAML.parse and YAML.stringify across data
types, edge cases, anchors/aliases, deep nesting, and round-trip
scenarios.

- Chores
- Added a YAML stringify benchmark script covering multiple libraries
and data shapes.

b93468ca48 Fix ESM <> CJS dual-package hazard determinism bug (#22231)
### 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.

### How did you verify your code works?

Unskipped tests. Plus manual.

684f7ecd09 Hide private fields in typeInfo (#22228)
ebe0cdac31..e0b7c318f3

It hides it in typeInfo even in the current file, unlike private
declarations which are only hidden in other files.

This allows you to formatted print a type with private fields, but the
private fields are not shown. The alternative would be to allow
accessing private fields through `@field()` but that looked like it was
going to be more complicated (need to add an argument to
structFieldVal/structFieldPtr which are called by fieldVal/fieldPtr
which have 36 callsites)

fe8f8242fd Make BoundedArray more compact, shrink Data in sql from 32 bytes to 24 bytes (#22210)
### What does this PR do?

- Instead of storing `len` in `BoundedArray` as a `usize`, store it as
either a `u8` or ` u16` depending on the `buffer_capacity`
- Copy-paste `BoundedArray` from the standard library into Bun's
codebase as it was removed in
https://github.com/ziglang/zig/pull/24699/files#diff-cbd8cbbc17583cb9ea5cc0f711ce0ad447b446e62ea5ddbe29274696dce89e4f
and we will probably continue using it

### How did you verify your code works?

Ran `bun run zig:check`

84604888e9 Private fields (#22189)
ZLS was tested manually and works with private fields (after restarting)

Zig diff:
d1a4e0b0dd..ebe0cdac31

ZLS diff:
15730e8e5d..3733f39c8d

Increases `zig build check` time by maybe 10ms?
