Update to zig 0.15.2 ( #24204 )
...
Fixes ENG-21287
Build times, from `bun run build && echo '//' >> src/main.zig && time
bun run build`
|Platform|0.14.1|0.15.2|Speedup|
|-|-|-|-|
|macos debug asan|126.90s|106.27s|1.19x|
|macos debug noasan|60.62s|50.85s|1.19x|
|linux debug asan|292.77s|241.45s|1.21x|
|linux debug noasan|146.58s|130.94s|1.12x|
|linux debug use_llvm=false|n/a|78.27s|1.87x|
|windows debug asan|177.13s|142.55s|1.24x|
Runtime performance:
- next build memory usage may have gone up by 5%. Otherwise seems the
same. Some code with writers may have gotten slower, especially one
instance of a counting writer and a few instances of unbuffered writers
that now have vtable overhead.
- File size reduced by 800kb (from 100.2mb to 99.4mb)
Improvements:
- `@export` hack is no longer needed for watch
- native x86_64 backend for linux builds faster. to use it, set use_llvm
false and no_link_obj false. also set `ASAN_OPTIONS=detect_leaks=0`
otherwise it will spam the output with tens of thousands of lines of
debug info errors. may need to use the zig lldb fork for debugging.
- zig test-obj, which we will be able to use for zig unit tests
Still an issue:
- false 'dependency loop' errors remain in watch mode
- watch mode crashes observed
Follow-up:
- [ ] search `comptime Writer: type` and `comptime W: type` and remove
- [ ] remove format_mode in our zig fork
- [ ] remove deprecated.zig autoFormatLabelFallback
- [ ] remove deprecated.zig autoFormatLabel
- [ ] remove deprecated.BufferedWriter and BufferedReader
- [ ] remove override_no_export_cpp_apis as it is no longer needed
- [ ] css Parser(W) -> Parser, and remove all the comptime writer: type
params
- [ ] remove deprecated writer fully

Fix Windows shell crash with && operator and external commands ( #22651 )
...
## What does this PR do?
Fixes https://github.com/oven-sh/bun/issues/22650
Fixes https://github.com/oven-sh/bun/issues/22615
Fixes https://github.com/oven-sh/bun/issues/22603
Fixes https://github.com/oven-sh/bun/issues/22602
Fixes a crash that occurred when running shell commands through `bun
run` (package.json scripts) on Windows that use the `&&` operator
followed by an external command.
### The Problem
The minimal reproduction was:
```bash
bun exec 'echo && node --version'
```
This would crash with: `panic(main thread): attempt to use null value`
### Root Causes
Two issues were causing the crash:
1. **Missing top_level_dir**: When `runPackageScriptForeground` creates
a MiniEventLoop for running package scripts, it wasn't setting the
`top_level_dir` field. This caused a null pointer dereference when the
shell tried to access it.
2. **MovableIfWindowsFd handling**: After PR #21800 introduced
`MovableIfWindowsFd` to handle file descriptor ownership on Windows, the
`IOWriter.fd` could be moved to libuv, leaving it null. When the shell
tried to spawn an external command after a `&&` operator, it would crash
trying to access this null fd.
### The Fix
1. Set `mini.top_level_dir = cwd` after initializing the MiniEventLoop
in `run_command.zig`
2. In `IO.zig`, when the fd has been moved to libuv (is null), use
`.inherit` for stdio instead of trying to pass the null fd
### How did you verify your code works?
- Added a regression test that reproduces the issue
- Verified the test fails without the fix and passes with it
- Tested the minimal reproduction command directly
- The fix correctly allows both commands in the `&&` chain to execute
```bash
# Before fix: crashes
> bun exec 'echo test && node --version'
panic(main thread): attempt to use null value
# After fix: works correctly
> bun exec 'echo test && node --version'
test
v22.4.1
```

Replace catch bun.outOfMemory() with safer alternatives ( #22141 )
...
Replace `catch bun.outOfMemory()`, which can accidentally catch
non-OOM-related errors, with either `bun.handleOom` or a manual `catch
|err| switch (err)`.
(For internal tracking: fixes STAB-1070)
