Enable compiler flags
Update SQLite amalgamation using https://www.sqlite.org/download.html
source code
[sqlite-src-3500400.zip](https://www.sqlite.org/2025/sqlite-src-3500400.zip)
with:
```bash
./configure CFLAGS="-DSQLITE_ENABLE_UPDATE_DELETE_LIMIT"
make sqlite3.c
```
This is the same version that before just with this adicional flag that
must be enabled when generating the amalgamation so we are actually able
to use this option. You can also see that without this the build will
happen but the feature will not be enable
https://buildkite.com/bun/bun/builds/27940, as informed in
https://www.sqlite.org/howtocompile.html topic 5.
### How did you verify your code works?
Add in CI two tests that check if the feature is enabled on windows

### 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.

## 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.

Add `jsc.DecodedJSValue`, an extern struct which is ABI-compatible with
`JSC::JSValue`. (By contrast, `jsc.JSValue` is ABI-compatible with
`JSC::EncodedJSValue`.) This enables `jsc.Strong.get` to be more
efficient: it no longer has to call into C++.

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`.

### What does this PR do?
Replaces '.upgrade()' with '.cloneUpgrade()'. '.upgrade()' is confusing
and `.clone().upgrade()` was causing a leak. Caught by
https://github.com/oven-sh/bun/pull/23199#discussion_r2400667320
### How did you verify your code works?
## 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)

## 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")

# 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
### What does this PR do?
This PR enables `--useExplicitResourceManagement` JSC option by default,
to expose following builtins:
- `DisposableStack`
- `AsyncDisposableStack`
- `Iterator@@dispose`
- `AsyncIterator@@asyncDispose`
### How did you verify your code works?
These features are fully tested on JSC side.
Multiple inline snapshots from one call should be avoided because they
will cause problems if one changes but not the other, but this allows
them if they both have the same value.

* 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

### How did you verify your code works?
Run valkey.test.ts duplicate tests 1k times
## 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

### 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

## 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

## 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.

### 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.
## Summary
This PR adds concise documentation for features introduced in Bun
v1.2.23 that were missing from the docs.
## Added Documentation
- **pnpm migration**: Automatic `pnpm-lock.yaml` to `bun.lock` migration
- **Platform filtering**: `--cpu` and `--os` flags for cross-platform
dependency installation
- **Test improvements**: Chaining test qualifiers (e.g.,
`.failing.each`)
- **CLI**: `bun feedback` command
- **TLS/SSL**: `--use-system-ca` flag and `NODE_USE_SYSTEM_CA`
environment variable
- **Node.js compat**: `process.report.getReport()` Windows support
- **Bundler**: New `jsx` configuration object in `Bun.build`
- **SQL**: `sql.array` helper for PostgreSQL arrays
## Test plan
Documentation changes only - reviewed for accuracy against the v1.2.23
release notes.
