## Summary
Fixed an unsigned integer underflow in the bounds check for
`writeBigInt64LE`, `writeBigInt64BE`, `writeBigUInt64LE`, and
`writeBigUInt64BE` methods.
## Problem
When `byteLength < 8`, the bounds check `offset > byteLength - 8` would
cause unsigned integer underflow (since both are `size_t`), resulting in
a large positive number that would pass the check. This allowed
out-of-bounds writes and caused ASAN use-after-poison errors.
**Reproduction:**
```js
const buf = Buffer.from("Hello World");
const slice = buf.slice(0, 5);
slice.writeBigUInt64BE(4096n, 10000); // ASAN error!
```
## Solution
Added an explicit `byteLength < 8` check before the subtraction to
prevent the underflow. The fix is applied to all four functions:
- `writeBigInt64LE` (src/bun.js/bindings/JSBuffer.cpp:2464)
- `writeBigInt64BE` (src/bun.js/bindings/JSBuffer.cpp:2504)
- `writeBigUInt64LE` (src/bun.js/bindings/JSBuffer.cpp:2543)
- `writeBigUInt64BE` (src/bun.js/bindings/JSBuffer.cpp:2582)
## Test plan
- Added comprehensive regression tests covering all edge cases
- Verified the original reproduction case now throws a proper RangeError
instead of crashing
- All tests pass

## Summary
Fixes an assertion failure that occurred when `URLSearchParams.toJSON()`
was called with numeric string keys.
## The Problem
When using numeric string keys (e.g., `"39208"`, `"0"`, `"100"`),
calling `toJSON()` would trigger:
```
ASSERTION FAILED: !parseIndex(propertyName)
cache/webkit-6d0f3aac0b817cc0/include/JavaScriptCore/JSObjectInlines.h:444
```
Reproduction:
```javascript
const params = new URLSearchParams();
params.set("39208", "updated");
params.toJSON(); // crashes
```
## Root Cause
The `getInternalProperties` function in `JSURLSearchParams.cpp` was
using `putDirect()` to add properties to the result object. However,
`putDirect()` cannot be used with property names that can be parsed as
array indices - JSC expects such properties to use indexed storage
instead.
## The Fix
- Replace `putDirect()` with `putDirectMayBeIndex()`, which
automatically handles both regular properties and numeric indices
- Replace `getDirect()` with `get()` to properly retrieve values for
both types of properties
## Test Plan
Added comprehensive tests to `test/js/web/html/URLSearchParams.test.ts`:
- ✅ Single numeric string keys
- ✅ Multiple numeric keys
- ✅ Mixed numeric and non-numeric keys
- ✅ Duplicate numeric keys
- ✅ Extra arguments (original crash case)
All tests pass, and the original crash no longer occurs.

## Summary
Fixes a panic that occurred when `console.log()` tried to format a Set
or Map instance with a non-numeric `size` property.
## Issue
When a Set or Map subclass overrides the `size` property with a
non-numeric value (like a constructor function, string, or other
object), calling `console.log()` on the instance would trigger a panic:
```javascript
class C1 extends Set {
constructor() {
super();
Object.defineProperty(this, "size", {
writable: true,
enumerable: true,
value: Set
});
console.log(this); // panic!
}
}
new C1();
```
## Root Cause
In `src/bun.js/ConsoleObject.zig`, the Map and Set formatting code
called `toInt32()` directly on the `size` property value. This function
asserts that the value is not a Cell (objects/functions), causing a
panic when `size` was overridden with non-numeric values.
## Solution
Changed both Map and Set formatting to use `coerce(i32, globalThis)`
instead of `toInt32()`. This properly handles non-numeric values using
JavaScript's standard type coercion rules and propagates any coercion
errors appropriately.
## Test Plan
Added regression tests to `test/js/bun/util/inspect.test.js` that verify
Set and Map instances with overridden non-numeric `size` properties can
be inspected without panicking.

### What does this PR do?
reduce memory usage when streaming (this should be a temporary solution
until owned_and_done is fixed)
### How did you verify your code works?
Added a test that should not be flaky in CI
---------
Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
### What does this PR do?
Fixes unhelpful FFI error messages that made debugging extremely
difficult. The user reported that when dlopen fails, the error doesn't
tell you which library failed or why.
**Before:**
```
Failed to open library. This is usually caused by a missing library or an invalid library path.
```
**After:**
```
Failed to open library "libnonexistent.so": /path/libnonexistent.so: cannot open shared object file: No such file or directory
```
### How did you verify your code works?
1. **Cross-platform compilation verified**
- Ran `bun run zig:check-all` - all platforms compile successfully
(Windows, macOS x86_64/arm64, Linux x86_64/arm64 glibc/musl)
2. **Added comprehensive regression tests**
(`test/regression/issue/dlopen-missing-symbol-error.test.ts`)
- ✅ Tests dlopen error shows library name when it can't be opened
- ✅ Tests dlopen error shows symbol name when symbol isn't found
- ✅ Tests linkSymbols shows helpful error when ptr is missing
- ✅ Tests handle both glibc and musl libc systems
3. **Manually tested error messages**
- Missing library: Shows full path and "No such file or directory"
- Invalid library: Shows "invalid ELF header"
- Missing symbol: Shows symbol and library name
- linkSymbols without ptr: Shows helpful explanation
### Implementation Details
1. **Created cross-platform getDlError() helper**
(src/bun.js/api/ffi.zig:8-21)
- On POSIX: Calls `std.c.dlerror()` to get actual system error message
- On Windows: Returns generic message (detailed errors handled in C++
layer via `GetLastError()` + `FormatMessageW()`)
- Follows the pattern established in `BunProcess.cpp` for dlopen error
handling
2. **Improved error messages**
- dlopen errors now include library name and system error details
- linkSymbols errors explain the ptr field requirement clearly
- Symbol lookup errors already showed both symbol and library name
3. **Fixed linkSymbols error propagation** (src/js/bun/ffi.ts:529)
- Added missing `if (Error.isError(result)) throw result;` check
- Now consistent with dlopen which already had this check
### Example Error Messages
- **Missing library:** `Failed to open library "libnonexistent.so":
cannot open shared object file: No such file or directory`
- **Invalid library:** `Failed to open library "/etc/passwd": invalid
ELF header`
- **Missing symbol:** `Symbol "nonexistent_func" not found in
"libc.so.6"`
- **Missing ptr:** `Symbol "myFunc" is missing a "ptr" field. When using
linkSymbols() or CFunction()...`

## Summary
Adds comprehensive support to `generate-classes.ts` for JavaScript
classes that need both named WriteBarrier members (like callbacks) and a
dynamic array of JSValues, all properly tracked by the garbage
collector. This replaces error-prone manual `protect()/unprotect()`
calls with proper GC integration.
## Motivation
The shell interpreter was using `JSValue.protect()/unprotect()` to keep
JavaScript objects alive, which caused memory leaks when cleanup paths
didn't properly unprotect values. This is a common pattern that needed a
better solution.
## What Changed
### Code Generator (`generate-classes.ts`)
When a class has both `values: ["resolve", "reject"]` and `valuesArray:
true`:
**Generated C++ class gets:**
- `WTF::FixedVector<JSC::WriteBarrier<JSC::Unknown>> jsvalueArray`
member for dynamic array
- Individual `JSC::WriteBarrier<JSC::Unknown> m_resolve, m_reject`
members for named values
- 4 `create()` overloads covering all combinations:
1. Basic: `create(vm, globalObject, structure, ptr)`
2. Array only: `create(..., FixedVector<WriteBarrier<Unknown>>&&)`
3. Named values: `create(..., JSValue resolve, JSValue reject)`
4. Both: `create(..., FixedVector&&, JSValue resolve, JSValue reject)`
**Constructor overloads using `WriteBarrierEarlyInit`:**
```cpp
JSShellInterpreter(VM& vm, Structure* structure, void* ptr,
JSValue resolve, JSValue reject)
: Base(vm, structure)
, m_resolve(resolve, JSC::WriteBarrierEarlyInit) // ← Key technique
, m_reject(reject, JSC::WriteBarrierEarlyInit)
{
m_ctx = ptr;
}
```
The `WriteBarrierEarlyInit` tag allows initializing WriteBarriers in the
constructor initializer list before the object is fully constructed,
which is required for proper GC integration.
**Extern C bridge functions:**
- `TypeName__createWithValues(globalObject, ptr, markedArgumentBuffer*)`
- `TypeName__createWithInitialValues(globalObject, ptr, resolve,
reject)`
- `TypeName__createWithValuesAndInitialValues(globalObject, ptr,
buffer*, resolve, reject)`
**Zig convenience wrappers:**
- `toJSWithValues(this, globalObject, markedArgumentBuffer)`
- `toJSWithInitialValues(this, globalObject, resolve, reject)`
- `toJSWithValuesAndInitialValues(this, globalObject, buffer, resolve,
reject)`
### Shell Interpreter Memory Leak Fix
**Before:**
```zig
const js_value = JSShellInterpreter.toJS(interpreter, globalThis);
resolve.protect(); // Manual reference counting
reject.protect();
// ... later in cleanup ...
resolve.unprotect(); // Easy to forget/miss in error paths
reject.unprotect();
```
**After:**
```zig
const js_value = Bun__createShellInterpreter(
globalThis,
interpreter,
parsed_shell_script,
resolve, // Stored with WriteBarrierEarlyInit
reject, // GC tracks automatically
);
// No manual memory management needed!
```
### Supporting Changes
- Added `MarkedArgumentBuffer.wrap()` helper in Zig for safe
MarkedArgumentBuffer usage
- Created `ShellBindings.cpp` with `Bun__createShellInterpreter()` using
the new API
- Removed all `protect()/unprotect()` calls from shell interpreter
- Applied pattern to both `ShellInterpreter` and `ShellArgs` classes
## Benefits
1. **No memory leaks**: GC tracks all references automatically
2. **Safer**: Cannot forget to unprotect values
3. **Cleaner code**: No manual reference counting
4. **Reusable**: Pattern works for any class needing to store JSValues
5. **Performance**: Same cost as manual protect/unprotect but safer
## Testing
Existing shell tests verify the functionality. The pattern is already
used throughout JavaScriptCore for similar cases (see
`JSWrappingFunction`, `AsyncContextFrame`, `JSModuleMock`, etc.)
## When to Use This Pattern
Use `values` + `valuesArray` + `WriteBarrierEarlyInit` when:
- Your C++ class needs to keep JavaScript values alive
- You have both known named callbacks AND dynamic arrays of values
- You want the GC to track references instead of manual
protect/unprotect
- Your class extends `JSDestructibleObject`

## 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 }}`

### 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
- 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)

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.
### What does this PR do?
bad:
```ts
function oops(a) {
expect(a).toMatchInlineSnapshot();
}
test("whoops", () => {
oops(1);
oops(2);
});
```
```
2 | expect(a).toMatchInlineSnapshot();
^
error: Failed to update inline snapshot: Multiple inline snapshots on the same line must all have the same value:
Expected: 1
Received: 2
at /Users/pfg/Dev/Node/bun/repro.ts:2:35
```
acceptable:
```ts
function ok(a) {
expect(a).toMatchInlineSnapshot(`1`);
}
test("whokay", () => {
ok(1);
ok(1);
});
```
```
✓ whokay
1 pass
0 fail
snapshots: +1 added
2 expect() calls

## 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
