### What does this PR do?
Three things:
- JSCommonJSExtensions.cpp `onAssign` was returning out of sync numbers
instead of `BunLoaderTypeJS`/`BunLoaderTypeNAPI`/...
- `bun.schema.api.Loader._none` was 255 instead of 254 like
`BunLoaderTypeNone`
- `Bun__transpileFile` used `bun.options.Loader.Optional` instead of
`bun.schema.api.Loader`. `bun.options.Loader` does not have a type kept
in sync in C++.
### How did you verify your code works?
Added tests that make sure the correct loader is used for modules
required with custom _extensions functions
### What does this PR do?
Fixes a bug since Bun v1.0.15: `var f = ([1, 2], "hi");`
Fixes a regression since Bun v1.2.22: `var f = (new Array([1, 2]),
"hi");`
Fixes#23287

* includes a better error if a package cant be met because of the age
(but would normally)
* logs the resolved one in --verbose (which can be helpful in debugging
to show it does know latest but couldn't use)
* makes bun outdated show in the table when the package isn't true
latest
* includes a rudimentary "stability" check if a later version is in
blacked out time (but only up to 7 days as it goes back to latest with
min age)
For extended security we could also Last-Modified header of the tgz
download and then abort if too new (just like the hash)

### 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
runtime).
This pr fixes the regression making sure `return (typeof x !==
"undefined", false);` minifies correctly to `return !1;`.

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]
```

## 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

## 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

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`.

## 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")

## 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

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.

## 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
