Created separate JSYogaConfigOwner to properly handle YogaConfigImpl objects
instead of incorrectly using JSYogaNodeOwner which expects YogaNodeImpl.
The issue was:
- YogaConfigImpl used jsYogaNodeOwner() WeakHandleOwner
- JSYogaNodeOwner::isReachableFromOpaqueRoots cast context to YogaNodeImpl*
- When called with YogaConfigImpl*, this caused type confusion and potential memory corruption
Fix:
- Created JSYogaConfigOwner with proper YogaConfigImpl handling
- YogaConfigImpl now uses jsYogaConfigOwner() instead of jsYogaNodeOwner()
- JSYogaConfigOwner doesn't use opaque roots (configs don't need them)
Progress:
- ✅ 2-3 yoga test files: All combinations work without ASAN errors
- ❌ 4+ yoga test files: Still ASAN error, possibly related to yoga-node-extended.test.js

Added visitOutputConstraints to JSYogaNode and JSYogaConfig to handle
GC output constraints as described in BunGCOutputConstraint.cpp documentation.
This pattern is required for objects with "volatile" marking behavior whose
references can change dynamically during JS execution, which applies to:
- Yoga node hierarchies (parent-child relationships change via insertChild/removeChild)
- Dynamic callbacks (measure, dirtied, baseline functions)
- Config references that can change during JS execution
Implementation follows WebKit pattern:
- visitOutputConstraints calls Base::visitOutputConstraints + visitAdditionalChildren
- Classes are auto-registered to output constraint spaces by detecting visitOutputConstraints
ASAN heap-use-after-free still occurs when running multiple Yoga test files
together, indicating deeper memory management issue remains.

Based on WebKit GC guide, replaced DECLARE_VISIT_CHILDREN with proper
visitAdditionalChildren pattern for RefCounted C++ objects with opaque roots.
Changes:
- Replace DECLARE_VISIT_CHILDREN with template<typename Visitor> visitAdditionalChildren
- Use DEFINE_VISIT_ADDITIONAL_CHILDREN instead of DEFINE_VISIT_CHILDREN
- Remove Base::visitChildren calls (handled automatically by JSC)
- Keep opaque root management for yoga node hierarchy
Issue: ASAN heap-buffer-overflow still occurs when running multiple
Yoga test files together, suggesting deeper memory management issue
beyond GC visitation pattern.

This implements the proper C++ wrapper lifecycle management pattern for Yoga nodes:
- Created YogaNodeImpl class that inherits from RefCounted<YogaNodeImpl>
- Updated JSYogaNode to hold Ref<YogaNodeImpl> instead of direct YGNodeRef
- Added JSC::Weak<JSYogaNode> to YogaNodeImpl for JS wrapper tracking
- Implemented JSYogaNodeOwner with proper opaque root GC lifecycle
- Added opaque root handling using root Yoga node traversal
- Finalize function properly derefs the C++ wrapper
This follows WebKit DOM patterns for proper GC lifecycle management.
Still needs some cleanup in JSYogaPrototype.cpp method calls.

* Broadened cross-platform applicability by removing OS-specific gating
in certain tests, ensuring they run consistently across environments.
* Activated additional scenarios around resolve/load behavior, dead code
elimination, package.json handling, and extra edge cases.
* No impact on runtime behavior or public APIs; changes are limited to
test execution and reliability.

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)

await sql`INSERT INTO test1 (uuid) VALUES (gen_random_uuid())`;
type Row = {
id: number;
uuid: string;
};
for (let i = 0; i < 100_000; i++) {
const [original]: Array<Row> = await conn1`SELECT id, uuid FROM test1 LIMIT 1`;
const [updated]: Array<Row> =
await conn1`UPDATE test1 SET uuid = gen_random_uuid() WHERE id = ${original.id} RETURNING id, uuid`;
const [retrieved]: Array<Row> = await conn2`SELECT id, uuid FROM test1 WHERE id = ${original.id}`;
if (retrieved.uuid !== updated.uuid) {
console.log("Expected retrieved and updated to match", retrieved, updated, i);
break;
}

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

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>
```
## Summary
- Fixed allocator threading violation when `BUN_INSPECT_CONNECT_TO` is
set
- Created thread-local `env_loader` with proper allocator isolation in
debugger thread
- Added regression test to verify the fix works correctly
## Problem
When `BUN_INSPECT_CONNECT_TO` environment variable is set, Bun creates a
debugger thread that spawns its own `VirtualMachine` instance.
Previously, this VM would fall back to the global `DotEnv.instance`
which was created with the main thread's allocator, causing threading
violations when the debugger thread accessed environment files via
`--env-file` or other env loading operations.
## Solution
Modified `startJSDebuggerThread` in `src/bun.js/Debugger.zig` to:
1. Create a thread-local `DotEnv.Map` and `DotEnv.Loader` using the
debugger thread's allocator
2. Pass this thread-local `env_loader` to `VirtualMachine.init()` to
ensure proper allocator isolation
3. Prevent sharing of allocators across threads
## Test plan
- [x] Added regression test in
`test/regression/issue/test_env_loader_threading.test.ts`
- [x] Verified basic Bun functionality still works
- [x] Test passes with both normal execution and with
`BUN_INSPECT_CONNECT_TO` set

## Summary
Fixes an issue where compiled standalone binaries included an extra
executable name argument in `process.argv`, breaking code that uses
`node:util.parseArgs()` with `process.argv.slice(2)`.
## Problem
When running a compiled binary, `process.argv` incorrectly included the
executable name as a third argument:
```bash
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app", "./my-app"] # BUG
```
This caused `parseArgs()` to fail with "Unexpected argument" errors,
breaking previously valid code.
## Solution
Fixed the `offset_for_passthrough` calculation in `cli.zig` to always
skip the executable name for standalone binaries, ensuring
`process.argv` only contains the runtime name and script path:
```bash
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app"] # FIXED
```
## Test plan
- [x] Added regression test in `test/regression/issue/22157.test.ts`
- [x] Verified existing exec-argv functionality still works correctly
- [x] Manual testing confirms the fix resolves the parseArgs issue
