edb7214e6c feat(perf_hooks): Implement monitorEventLoopDelay() for Node.js compatibility (#22429)
## Summary
This PR implements `perf_hooks.monitorEventLoopDelay()` for Node.js
compatibility, enabling monitoring of event loop delays and collection
of performance metrics via histograms.

Fixes #17650

## Implementation Details

### JavaScript Layer (`perf_hooks.ts`)
- Added `IntervalHistogram` class with:
  - `enable()` / `disable()` methods with proper state tracking
  - `reset()` method to clear histogram data
  - Properties: `min`, `max`, `mean`, `stddev`, `exceeds`, `percentiles`
  - `percentile(p)` method with validation
- Full input validation matching Node.js behavior (TypeError vs
RangeError)

### C++ Bindings (`JSNodePerformanceHooksHistogramPrototype.cpp`)
- `jsFunction_monitorEventLoopDelay` - Creates histogram for event loop
monitoring
- `jsFunction_enableEventLoopDelay` - Enables monitoring and starts
timer
- `jsFunction_disableEventLoopDelay` - Disables monitoring and stops
timer
- `JSNodePerformanceHooksHistogram_recordDelay` - Records delay
measurements

### Zig Implementation (`EventLoopDelayMonitor.zig`)
- Embedded `EventLoopTimer` that fires periodically based on resolution
- Tracks last fire time and calculates delay between expected vs actual
- Records delays > 0 to the histogram
- Integrates seamlessly with existing Timer system

## Testing
 All tests pass:
- Custom test suite with 8 comprehensive tests
- Adapted Node.js core test for full compatibility
- Tests cover enable/disable behavior, percentiles, error handling, and
delay recording

## Test plan
- [x] Run `bun test
test/js/node/perf_hooks/test-monitorEventLoopDelay.test.js`
- [x] Run adapted Node.js test
`test/js/node/test/sequential/test-performance-eventloopdelay-adapted.test.js`
- [x] Verify proper error handling for invalid arguments
- [x] Confirm delay measurements are recorded correctly

72490281e5 fix: handle empty chunked gzip responses correctly (#22360)
## Summary
Fixes #18413 - Empty chunked gzip responses were causing `Decompression
error: ShortRead`

## The Issue
When a server sends an empty response with `Content-Encoding: gzip` and
`Transfer-Encoding: chunked`, Bun was throwing a `ShortRead` error. This
occurred because the code was checking if `avail_in == 0` (no input
data) and immediately returning an error, without attempting to
decompress what could be a valid empty gzip stream.

## The Fix
Instead of checking `avail_in == 0` before calling `inflate()`, we now:
1. Always call `inflate()` even when `avail_in == 0` 
2. Check the return code from `inflate()`
3. If it returns `BufError` with `avail_in == 0`, then we truly need
more data and return `ShortRead`
4. If it returns `StreamEnd`, it was a valid empty gzip stream and we
finish successfully

This approach correctly distinguishes between "no data yet" and "valid
empty gzip stream".

## Why This Works
- A valid empty gzip stream still has headers and trailers (~20 bytes)
- The zlib `inflate()` function can handle empty streams correctly  
- `BufError` with `avail_in == 0` specifically means "need more input
data"

## Test Plan
 Added regression test in `test/regression/issue/18413.test.ts`
covering:
- Empty chunked gzip response
- Empty non-chunked gzip response  
- Empty chunked response without gzip

 Verified all existing gzip-related tests still pass
 Tested with the original failing case from the issue

e1de7563e1 Fix PostgreSQL TIME and TIMETZ binary format handling (#22354)
## Summary
- Fixes binary format handling for PostgreSQL TIME and TIMETZ data types
- Resolves issue where time values were returned as garbled binary data
with null bytes

## Problem
When PostgreSQL returns TIME or TIMETZ columns in binary format, Bun.sql
was not properly converting them from their binary representation
(microseconds since midnight) to readable time strings. This resulted in
corrupted output like `\u0000\u0000\u0000\u0000\u0076` instead of proper
time values like `09:00:00`.

## Solution
Added proper binary format decoding for:
- **TIME (OID 1083)**: Converts 8 bytes of microseconds since midnight
to `HH:MM:SS.ffffff` format
- **TIMETZ (OID 1266)**: Converts 8 bytes of microseconds + 4 bytes of
timezone offset to `HH:MM:SS.ffffff±HH:MM` format

## Changes
- Added binary format handling in `src/sql/postgres/DataCell.zig` for
TIME and TIMETZ types
- Added `InvalidTimeFormat` error to `AnyPostgresError` error set
- Properly formats microseconds with trailing zero removal
- Handles timezone offsets correctly (PostgreSQL uses negative values
for positive UTC offsets)

## Test plan
Added comprehensive tests in `test/js/bun/sql/postgres-time.test.ts`:
- [x] TIME and TIMETZ column values with various formats
- [x] NULL handling
- [x] Array types (TIME[] and TIMETZ[])
- [x] JSONB structures containing time strings
- [x] Verification that no binary/null bytes appear in output

All tests pass locally with PostgreSQL.

e2bfeefc9d Fix shell crash when piping assignments into commands (#22336)
## Summary
- Fixes crash when running shell commands with variable assignments
piped to other commands
- Resolves #15714

## Problem
The shell was crashing with "Invalid tag" error when running commands
like:
```bash
bun exec "FOO=bar BAR=baz | echo hi"
```

## Root Cause
In `Pipeline.zig`, the `cmds` array was allocated with the wrong size:
- It used `node.items.len` (which includes assignments)
- But only filled entries for actual commands (assignments are skipped
in pipelines)
- This left uninitialized memory that caused crashes when accessed

## Solution
Changed the allocation to use the correct `cmd_count` instead of
`node.items.len`:
```zig
// Before
this.cmds = if (cmd_count >= 1) bun.handleOom(this.base.allocator().alloc(CmdOrResult, this.node.items.len)) else null;

// After  
this.cmds = if (cmd_count >= 1) bun.handleOom(this.base.allocator().alloc(CmdOrResult, cmd_count)) else null;
```

## Test plan
 Added comprehensive regression test in
`test/regression/issue/15714.test.ts` that:
- Tests the exact case from the issue
- Tests multiple assignments
- Tests single assignment
- Tests assignments in middle of pipeline
- Verified test fails on main branch (exit code 133 = SIGTRAP)
- Verified test passes with fix

cff2c2690b Refactor Buffer.concat to use spans and improve error handling (#22337)
## Summary

This PR refactors the `Buffer.concat` implementation to use modern C++
spans for safer memory operations and adds proper error handling for
oversized buffers.

## Changes

- **Use spans instead of raw pointers**: Replaced pointer arithmetic
with `typedSpan()` and `span()` methods for safer memory access
- **Add MAX_ARRAY_BUFFER_SIZE check**: Added explicit check with a
descriptive error message when attempting to create buffers larger than
JavaScriptCore's limit (4GB)
- **Improve loop logic**: Changed loop counter from `int` to `size_t`
and simplified the iteration using span sizes
- **Enhanced test coverage**: Updated tests to verify the new error
message and added comprehensive test cases for various Buffer.concat
scenarios

## Test Plan

All existing tests pass, plus added new tests:
-  Error handling for oversized buffers
-  Normal buffer concatenation
-  totalLength parameter handling (exact, larger, smaller)
-  Empty array handling
-  Single buffer handling

```bash
./build/debug/bun-debug test test/js/node/buffer-concat.test.ts
# Result: 6 pass, 0 fail
```

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.

2e8e7a000c Fix WebSocket to emit error event before close on handshake failure (#22325)
## Summary
This PR fixes WebSocket to correctly emit an `error` event before the
`close` event when the handshake fails (e.g., 302 redirects, non-101
status codes, missing headers).

Fixes #14338

## Problem
Previously, when a WebSocket connection failed during handshake (like
receiving a 302 redirect or connecting to a non-WebSocket server), Bun
would only emit a `close` event. This behavior differed from the WHATWG
WebSocket specification and other runtimes (browsers, Node.js with `ws`,
Deno) which emit both `error` and `close` events.

## Solution
Modified `WebSocket::didFailWithErrorCode()` in `WebSocket.cpp` to pass
`isConnectionError = true` for all handshake failure error codes,
ensuring an error event is dispatched before the close event when the
connection is in the CONNECTING state.

## Changes
- Updated error handling in `src/bun.js/bindings/webcore/WebSocket.cpp`
to emit error events for handshake failures
- Added comprehensive test coverage in
`test/regression/issue/14338.test.ts`

## Test Coverage
The test file includes:
1. **Negative test**: 302 redirect response - verifies error event is
emitted
2. **Negative test**: Non-WebSocket HTTP server - verifies error event
is emitted
3. **Positive test**: Successful WebSocket connection - verifies NO
error event is emitted

All tests pass with the fix applied.

ad1fa514ed Add fast path for simple objects in postMessage and structuredClone (#22279)
## Summary
- Extends the existing string fast path to support simple objects with
primitive values
- Achieves 2-241x performance improvements for postMessage with objects
- Maintains compatibility with existing code while significantly
reducing overhead

## Performance Results

### Bun (this PR)
```
postMessage({ prop: 11 chars string, ...9 more props }) - 648ns (was 1.36µs) 
postMessage({ prop: 14 KB string, ...9 more props })    - 719ns (was 2.09µs)
postMessage({ prop: 3 MB string, ...9 more props })      - 1.26µs (was 168µs)
```

### Node.js v24.6.0 (for comparison)
```
postMessage({ prop: 11 chars string, ...9 more props }) - 1.19µs
postMessage({ prop: 14 KB string, ...9 more props })    - 2.69µs  
postMessage({ prop: 3 MB string, ...9 more props })      - 304µs
```

## Implementation Details

The fast path activates when:
- Object is a plain object (ObjectType or FinalObjectType)
- Has no indexed properties
- All property values are primitives or strings
- No transfer list is involved

Properties are stored in a `SimpleInMemoryPropertyTableEntry` vector
that holds property names and values directly, avoiding the overhead of
full serialization.

## Test plan
- [x] Added tests for memory usage with simple objects
- [x] Added test for objects exceeding JSFinalObject::maxInlineCapacity
- [x] Created benchmark to verify performance improvements
- [x] Existing structured clone tests continue to pass

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);
// # output
// {one: {two: three}}
```

### How did you verify your code works?
Added tests for basic use and edgecases

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## 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.

25c61fcd5a Fix structuredClone pointer advancement and File name preservation for Blob/File objects (#22282)
## Summary

Fixes #20596 

This PR resolves the "Unable to deserialize data" error when using
`structuredClone()` with nested objects containing `Blob` or `File`
objects, and ensures that `File` objects preserve their `name` property
during structured clone operations.

## Problem

### Issue 1: "Unable to deserialize data" Error
When cloning nested structures containing Blob/File objects,
`structuredClone()` would throw:
```
TypeError: Unable to deserialize data.
```

**Root Cause**: The `StructuredCloneableDeserialize::fromTagDeserialize`
function wasn't advancing the pointer (`m_ptr`) after deserializing
Blob/File objects. This caused subsequent property reads in nested
scenarios to start from the wrong position in the serialized data.

**Affected scenarios**:
-  `structuredClone(blob)` - worked fine (direct cloning)
-  `structuredClone({blob})` - threw error (nested cloning)
-  `structuredClone([blob])` - threw error (array cloning) 
-  `structuredClone({data: {files: [file]}})` - threw error (complex
nesting)

### Issue 2: File Name Property Lost
Even when File cloning worked, the `name` property was not preserved:
```javascript
const file = new File(["content"], "test.txt");
const cloned = structuredClone(file);
console.log(cloned.name); // undefined (should be "test.txt")
```

**Root Cause**: The structured clone serialization only handled basic
Blob properties but didn't serialize/deserialize the File-specific
`name` property.

## Solution

### Part 1: Fix Pointer Advancement

**Modified Code Generation** (`src/codegen/generate-classes.ts`):
- Changed `fromTagDeserialize` function signature from `const uint8_t*`
to `const uint8_t*&` (pointer reference)
- Updated implementation to cast pointer correctly: `(uint8_t**)&ptr`
- Fixed both C++ extern declarations and Zig wrapper signatures

**Updated Zig Functions**:
- **Blob.zig**: Modified `onStructuredCloneDeserialize` to take `ptr:
*[*]u8` and advance it by `buffer_stream.pos`
- **BlockList.zig**: Applied same fix for consistency across all
structured clone types

### Part 2: Add File Name Preservation

**Enhanced Serialization Format**:
- Incremented serialization version from 2 to 3 to support File name
serialization
- Added File name serialization using `getNameString()` to handle all
name storage scenarios
- Added proper deserialization with `bun.String.cloneUTF8()` for UTF-8
string creation
- Maintained backwards compatibility with existing serialization
versions

## Testing

Created comprehensive test suite
(`test/js/web/structured-clone-blob-file.test.ts`) with **24 tests**
covering:

### Core Functionality
- Direct Blob/File cloning (6 tests)
- Nested Blob/File in objects and arrays (8 tests) 
- Mixed Blob/File scenarios (4 tests)

### Edge Cases
- Blob/File with empty data (6 tests)
- File with empty data and empty name (2 tests)

### Regression Tests
- Original issue 20596 reproduction cases (3 tests)

**Results**: All **24/24 tests pass** (up from 5/18 before the fix)

## Key Changes

1. **src/codegen/generate-classes.ts**:
   - Updated `fromTagDeserialize` signature and implementation
   - Fixed C++ extern declarations for pointer references

2. **src/bun.js/webcore/Blob.zig**:
   - Enhanced pointer advancement in deserialization
   - Added File name serialization/deserialization
   - Incremented serialization version with backwards compatibility

3. **src/bun.js/node/net/BlockList.zig**:
   - Applied consistent pointer advancement fix

4. **test/js/web/structured-clone-blob-file.test.ts**:
   - Comprehensive test suite covering all scenarios and edge cases

## Backwards Compatibility

-  Existing structured clone functionality unchanged
-  All other structured clone tests continue to pass (118/118 worker
tests pass)
-  Serialization version 3 supports versions 1-2 with proper fallback
-  No breaking changes to public APIs

## Performance Impact

-  No performance regression in existing functionality
-  Minimal overhead for File name serialization (only when
`is_jsdom_file` is true)
-  Efficient pointer arithmetic for advancement

c69ed120e9 Rename some instances of latin1 to cp1252 (#22059)
in JS, `new TextDecoder("latin1").decode(...)` uses cp1252. In python,
latin1 is half-width utf-16. In our code, latin1 typically refers to
half-width utf-16 because JavaScriptCore uses that for most strings, but
sometimes it refers to cp1252. Rename the cp1252 functions to be called
cp1252

Also fixes an issue where Buffer.from with utf-16le would sometimes
output the wrong value:

```js
$> bun -p "Buffer.from('\x80', 'utf-16le')"
<Buffer ac 20>
$> node -p "Buffer.from('\x80', 'utf-16le')"
<Buffer 80 00>
$> bun-debug -p "Buffer.from('\x80', 'utf-16le')"
<Buffer 80 00>

707fc4c3a2 Introduce Bun.secrets API (#21973)
This PR adds `Bun.secrets`, a new API for securely storing and
retrieving credentials using the operating system's native credential
storage locally. This helps developers avoid storing sensitive data in
plaintext config files.

```javascript
// Store a GitHub token securely
await Bun.secrets.set({
  service: "my-cli-tool",
  name: "github-token",
  value: "ghp_xxxxxxxxxxxxxxxxxxxx"
});

// Retrieve it when needed
const token = await Bun.secrets.get({
  service: "my-cli-tool",
  name: "github-token"
});

// Use with fallback to environment variable
const apiKey = await Bun.secrets.get({
  service: "my-app",
  name: "api-key"
}) || process.env.API_KEY;
```

Marking this as a draft because Linux and Windows have not been manually
tested yet. This API is only really meant for local development usecases
right now, but it would be nice if in the future to support adapters for
production or CI usecases.

### Core API
- `Bun.secrets.get({ service, name })` - Retrieve a stored credential
- `Bun.secrets.set({ service, name, value })` - Store or update a
credential
- `Bun.secrets.delete({ service, name })` - Delete a stored credential

### Platform Support
- **macOS**: Uses Keychain Services via Security.framework
- **Linux**: Uses libsecret (works with GNOME Keyring, KWallet, etc.)
- **Windows**: Uses Windows Credential Manager via advapi32.dll

### Implementation Highlights
- Non-blocking - all operations run on the threadpool
- Dynamic loading - no hard dependencies on system libraries
- Sensitive data is zeroed after use
- Consistent API across all platforms

## Use Cases

This API is particularly useful for:
- CLI tools that need to store authentication tokens
- Development tools that manage API keys
- Any tool that currently stores credentials in `~/.npmrc`,
`~/.aws/credentials` or in environment variables that're globally loaded

## Testing

Comprehensive test suite included with coverage for:
- Basic CRUD operations
- Empty strings and special characters
- Unicode support
- Concurrent operations
- Error handling

All tests pass on macOS. Linux and Windows implementations are complete
but would benefit from additional platform testing.

## Documentation

- Complete API documentation in `docs/api/secrets.md`
- TypeScript definitions with detailed JSDoc comments and examples

8fad98ffdb Add Bun.YAML.parse and YAML imports (#22073)
### What does this PR do?
This PR adds builtin YAML parsing with `Bun.YAML.parse`
```js
import { YAML } from "bun";
const items = YAML.parse("- item1");
console.log(items); // [ "item1" ]
```

Also YAML imports work just like JSON and TOML imports
```js
import pkg from "./package.yaml"
console.log({ pkg }); // { pkg: { name: "pkg", version: "1.1.1" } }
```
### How did you verify your code works?
Added some tests for YAML imports and parsed values.

b2351bbb4e Add Symbol.asyncDispose to Worker in worker_threads (#22064)
## Summary

- Implement `Symbol.asyncDispose` for the `Worker` class in
`worker_threads` module
- Enables automatic resource cleanup with `await using` syntax
- Calls `await this.terminate()` to properly shut down workers when they
go out of scope

## Implementation Details

The implementation adds a simple async method to the Worker class:

```typescript
async [Symbol.asyncDispose]() {
  await this.terminate();
}
```

This allows workers to be used with the new `await using` syntax for
automatic cleanup:

```javascript
{
  await using worker = new Worker('./worker.js');
  // worker automatically terminates when leaving this scope
}
```

## Test Plan

- [x] Added comprehensive tests for `Symbol.asyncDispose` functionality
- [x] Tests verify the method exists and returns undefined
- [x] Tests verify `await using` syntax works correctly for automatic
worker cleanup
- [x] All new tests pass
- [x] Existing worker_threads functionality remains intact

92b38fdf80 sql: support array of strings in SQLHelper (#21572)
### What does this PR do?
Support the following:
```javascript
const nom = await sql`SELECT name FROM food WHERE category IN ${sql(['bun', 'baozi', 'xiaolongbao'])}`;
```

Previously, only e.g., `sql([1, 2, 3])` was supported.

To be honest I'm not sure what the semantics of SQLHelper *ought* to be.
I'm pretty sure objects ought to be auto-inferred. I'm not sure about
arrays, but given the rest of the code in `SQLHelper` trying to read the
tea leaves on stringified numeric keys I figured someone cared about
this use case. I don't know about other types, but I'm pretty sure that
`Object.keys("bun") === [0, 1, 2]` is an oversight and unintended.
(Incidentally, the reason numbers previously worked is because
`Object.keys(4) === []`). I decided that all non-objects and non-arrays
should be treated as not having auto-inferred columns.

Fixes #18637 

### How did you verify your code works?
I wrote a test, but was unable to run it (or any other tests in this
file) locally due to Docker struggles. I sure hope it works!

e3e8d15263 Fix redis reconnecting (#21724)
### What does this PR do?

This PR fixes https://github.com/oven-sh/bun/issues/19131.

I am not 100% certain that this fix is correct as I am still nebulous
regarding some decisions I've made in this PR. I'll try to provide my
reasoning and would love to be proven wrong:

#### Re-authentication

- The `is_authenticated` flag needs to be reset to false. When the
lifecycle reaches a point of attempting to connect, it sends out a
`HELLO 3`, and receives a response. `handleResponse()` is fired and does
not correctly handle it because there is a guard at the top of the
function:

```zig
if (!this.flags.is_authenticated) {
    this.handleHelloResponse(value);

    // We've handled the HELLO response without consuming anything from the command queue
    return;
}
```

Rather, it treats this packet as a regular data packet and complains
that it doesn't have a promise to associate it to. By resetting the
`is_authenticated` flag to false, we guarantee that we handle the `HELLO
3` packet as an authentication packet.

It also seems to make semantic sense since dropping a connection implies
you dropped authentication.

#### Retry Attempts

I've deleted the `retry_attempts = 0` in `reconnect()` because I noticed
that we would never actually re-attempt to reconnect after the first
attempt. Specifically, I was expecting `valkey.zig:459` to potentially
fire multiple times, but it only ever fired once. Removing this reset to
zero caused successful reattempts (in my case 3 of them).

```zig
        debug("reconnect in {d}ms (attempt {d}/{d})", .{ delay_ms, this.retry_attempts, this.max_retries });
```

I'm still iffy on whether this is necessary, but I think it makes sense.
```zig
        this.client.retry_attempts = 0
```

### How did you verify your code works?

I have added a small unit test. I have compared mainline `bun`, which
fails that test, to this fix, which passes the test.

e7672b2d04 Add string fast path for postMessage and structuredClone (#21926)
## Summary

Implements a string fast path optimization for `postMessage` and
`structuredClone` operations that provides significant performance
improvements for string-only data transfer, along with various bug fixes
and infrastructure improvements.

## Key Performance Improvements

**postMessage with Workers:**
- **Small strings (11 chars):** ~5% faster (572ns vs 599ns)
- **Medium strings (14KB):** **~2.7x faster** (528ns vs 1.40μs) 
- **Large strings (3MB):** **~660x faster** (540ns vs 356μs)

**Compared to Node.js postMessage:**
- Similar performance for small strings
- Competitive for medium strings  
- **~455x faster** for large strings (540ns vs 245μs)

## Implementation Details

The optimization adds a **string fast path** that bypasses full
structured cloning serialization when:
- Input is a pure string (`value.isString()`)
- No transfer list or message ports are involved
- Not being stored persistently

### Core Changes

**String Thread-Safety Utilities (`BunString.cpp/h`):**
- `isCrossThreadShareable()` - Checks if string can be safely shared
across threads
- `toCrossThreadShareable()` - Converts strings to thread-safe form via
`isolatedCopy()`
- Handles edge cases: atoms, symbols, substring slices, external buffers

**Serialization Fast Path (`SerializedScriptValue.cpp`):**
- New `m_fastPathString` field stores string data directly
- Bypasses full object serialization machinery for pure strings
- Creates isolated copies for cross-thread safety

**Deserialization Fast Path:**
- Directly returns JSString from stored string data
- Avoids parsing serialized byte streams

**Updated Flags System (`JSValue.zig`, `Serialization.cpp`):**
- Replaces boolean `forTransfer` with structured `SerializedFlags`
- Supports `forCrossProcessTransfer` and `forStorage` distinctions

**Structured Clone Infrastructure:**
- Moved `structuredClone` implementation to dedicated
`StructuredClone.cpp`
- Added `jsFunctionStructuredCloneAdvanced` for testing with custom
flags
- Improved class serialization compatibility checks (`isForTransfer`,
`isForStorage`)

**IPC Improvements (`ipc.zig`):**
- Fixed race conditions in `SendQueue` by deferring cleanup to next tick
- Proper fd ownership handling with `bun.take()`
- Cached IPC serialize/parse functions for better performance

**BlockList Thread Safety Fixes (`BlockList.zig`):**
- Fixed potential deadlocks by moving mutex locking inside methods
- Added atomic `estimated_size` counter to avoid lock during GC
- Corrected pointer handling in comparison functions
- Improved GC safety in `rules()` method

## Benchmark Results

```
❯ bun-21926 bench/string-postmessage.mjs  # This branch
postMessage(11 chars string)  572.24 ns/iter
postMessage(14 KB string)     527.55 ns/iter  ← ~2.7x faster
postMessage(3 MB string)      539.70 ns/iter  ← ~660x faster

❯ bun-1.2.20 bench/string-postmessage.mjs  # Previous
postMessage(11 chars string)  598.76 ns/iter
postMessage(14 KB string)       1.40 µs/iter
postMessage(3 MB string)      356.38 µs/iter

❯ node bench/string-postmessage.mjs       # Node.js comparison  
postMessage(11 chars string)  569.63 ns/iter
postMessage(14 KB string)       1.46 µs/iter
postMessage(3 MB string)      245.46 µs/iter
```

**Key insight:** The fast path achieves **constant time performance**
regardless of string size (~540ns), while traditional serialization
scales linearly with data size.

## Test Coverage

**New Tests:**
- `test/js/web/structured-clone-fastpath.test.ts` - Fast path memory
usage validation
- `test/js/web/workers/structuredClone-classes.test.ts` - Comprehensive
class serialization tests
  - Tests ArrayBuffer transferability 
  - Tests BunFile cloning with storage/transfer restrictions
  - Tests net.BlockList cloning behavior
  - Validates different serialization contexts (default, worker, window)

**Enhanced Tests:**
- `test/js/web/workers/structured-clone.test.ts` - Multi-function
testing
- Tests `structuredClone`, `jscSerializeRoundtrip`, and cross-process
serialization
  - Validates consistency across different serialization paths
- `test/js/node/cluster.test.ts` - Better error handling and debugging

**Benchmarks:**
- `bench/string-postmessage.mjs` - Worker postMessage performance
comparison
- `bench/string-fastpath.mjs` - Fast path vs traditional serialization
comparison

## Bug Fixes

**BlockList Threading Issues:**
- Fixed potential deadlocks when multiple threads access BlockList
simultaneously
- Moved mutex locks inside methods rather than holding across entire
function calls
- Added atomic size tracking for GC compatibility
- Fixed comparison function pointer handling

**IPC Race Conditions:**
- Fixed race condition where `SendQueue._onAfterIPCClosed()` could be
called on wrong thread
- Deferred cleanup operations to next tick using task queue
- Improved file descriptor ownership with proper `bun.take()` usage

**Structured Clone Compatibility:**
- Enhanced class serialization with proper transfer/storage mode
checking
- Fixed edge cases where non-transferable objects were incorrectly
handled
- Added better error reporting for unsupported clone operations

## Technical Notes

- Thread safety ensured via `String.isolatedCopy()` for cross-VM
transfers
- Memory cost calculation updated to account for string references
- Maintains full compatibility with existing structured clone semantics
- Does not affect object serialization or transfer lists
- Proper cleanup and error handling throughout IPC pipeline
