c5def80191 Fix Output.enable_ansi_colors usage to check stdout vs stderr (#24212)
## Summary

Updated all 49 usages of `Output.enable_ansi_colors` to properly check
either `Output.enable_ansi_colors_stdout` or
`Output.enable_ansi_colors_stderr` based on their output destination.

This prevents bugs where ANSI colors are checked against the wrong
stream (e.g., checking stdout colors when writing to stderr).

## Changes

### Added
- `Output.enable_ansi_colors` now a `@compileError` to prevent future
misuse with helpful error message directing to correct variants

### Deleted
- `Output.isEmojiEnabled()` - replaced all usages with
`enable_ansi_colors_stderr` (all were error/progress output)
- `Output.prettyWithPrinterFn()` - removed unused dead code

### Updated by Output Destination

**Stderr (error/diagnostic output):**
- logger.zig: Log messages and errors
- crash_handler.zig: Crash reports and stack traces (10 instances)
- PackageInstaller.zig: Error messages from lifecycle scripts (3
instances)
- JSValue.zig: Test expectation error messages
- JSGlobalObject.zig: Exception throwing
- pack_command.zig: Progress indicators
- VirtualMachine.zig: Exception printing (2 instances)
- Test expect files: Test failure messages and diffs (10 instances)
- diff_format.zig: Test diff output
- ProgressStrings.zig: Package manager progress emojis (6 functions)
- security_scanner.zig: Security scan progress emoji
- output.zig: panic(), resetTerminal()

**Stdout (primary output/interactive UI):**
- hot_reloader.zig: Terminal clearing on reload
- Version.zig: Version diff formatting
- install_with_manager.zig: Package installation tree
- update_interactive_command.zig: Interactive update UI (2 instances)
- init_command.zig: Interactive radio buttons
- create_command.zig: Template creation output (2 instances)
- outdated_command.zig: Outdated packages table
- publish_command.zig: Box drawing characters (6 instances)

**Backward Compatible:**
- BunObject.zig: `Bun.enableANSIColors` property returns `(stdout ||
stderr)` to maintain compatibility
- fmt.zig: Removed unused `.default` field from Options struct

## Test Plan

-  All changes compile successfully with `bun run zig:check`
-  Verified all 49 usages have been updated to appropriate variant
-  Verified no remaining references to deprecated functions/variables
-  Compile error triggers if someone tries to use
`Output.enable_ansi_colors`

## Stats

- 24 files changed
- 58 insertions, 77 deletions (net -19 lines)
- 49 usages correctly updated
- 3 items deleted/deprecated

476e1cfe69 Make 'bun list' an alias for 'bun pm ls' (#24159)
## Summary

This PR makes `bun list` an alias for `bun pm ls`, allowing users to
list their dependency tree with a shorter command.

## Changes

- Updated `src/cli.zig` to route `list` command to
`PackageManagerCommand` instead of `ReservedCommand`
- Modified `src/cli/package_manager_command.zig` to detect when `bun
list` is invoked directly and treat it as `ls`
- Updated help text in `bun pm --help` to show both `bun list` and `bun
pm ls` as valid options

## Implementation Details

The implementation follows the same pattern used for `bun whoami`, which
is also a direct alias to a pm subcommand. When `bun list` is detected,
it's internally converted to the `ls` subcommand.

## Testing

Tested locally:
-  `bun list` shows the dependency tree
-  `bun list --all` works correctly with the `--all` flag
-  `bun pm ls` continues to work (backward compatible)

## Test Output

```bash
$ bun list
/tmp/test-bun-list node_modules (3)
└── react@18.3.1

$ bun list --all
/tmp/test-bun-list node_modules
├── js-tokens@4.0.0
├── loose-envify@1.4.0
└── react@18.3.1

$ bun pm ls
/tmp/test-bun-list node_modules (3)
└── react@18.3.1
```

a7fc6eb354 Implement --cpu-prof CLI flag (#24112)
## Summary

Implements the `--cpu-prof` CLI flag for Bun to profile CPU usage and
save results in Chrome CPU Profiler JSON format, compatible with Chrome
DevTools and VSCode.

## Implementation Details

- Uses JSC's `SamplingProfiler` to collect CPU samples during execution
- Converts samples to Chrome CPU Profiler JSON format on exit
- Supports `--cpu-prof-name` to customize output filename
- Supports `--cpu-prof-dir` to specify output directory
- Default filename: `CPU.YYYYMMDD.HHMMSS.PID.0.001.cpuprofile`

## Key Features

 **Chrome DevTools Compatible** - 100% compatible with Node.js CPU
profile format
 **Absolute Timestamps** - Uses wall clock time (microseconds since
epoch)
 **1ms Sampling** - Matches Node.js sampling frequency for comparable
granularity
 **Thread-Safe** - Properly shuts down background sampling thread
before processing
 **Memory-Safe** - Uses HeapIterationScope and DeferGC for safe heap
access
 **Cross-Platform** - Compiles on Windows, macOS, and Linux with proper
path handling

## Technical Challenges Solved

1. **Heap Corruption** - Fixed by calling `profiler->shutdown()` before
processing traces
2. **Memory Safety** - Added `HeapIterationScope` and `DeferGC` when
accessing JSCells
3. **Timestamp Accuracy** - Explicitly start stopwatch and convert to
absolute wall clock time
4. **Path Handling** - Used `bun.path.joinAbsStringBufZ` with proper cwd
resolution
5. **Windows Support** - UTF-16 path conversion for Windows
compatibility
6. **Atomic Writes** - Used `bun.sys.File.writeFile` with ENOENT retry

## Testing

All tests pass (4/4):
-  Generates profile with default name
-  `--cpu-prof-name` sets custom filename
-  `--cpu-prof-dir` sets custom directory
-  Profile captures function names

Verified format compatibility:
- JSON structure matches Node.js exactly
- All samples reference valid nodes
- Timestamps use absolute microseconds since epoch
- Cross-platform compilation verified with `bun run zig:check-all`

## Example Usage

```bash
# Basic usage
bun --cpu-prof script.js

# Custom filename
bun --cpu-prof --cpu-prof-name my-profile.cpuprofile script.js

# Custom directory
bun --cpu-prof --cpu-prof-dir ./profiles script.js
```

Output can be opened in Chrome DevTools (Performance → Load Profile) or
VSCode's CPU profiling viewer.

a3c43dc8b9 Fix Windows bunx fast path index out of bounds panic (#23938)
## Summary

Fixed a bug in the Windows bunx fast path code where UTF-8 byte length
was incorrectly used instead of UTF-16 code unit length when calculating
buffer offsets.

## Details

In `run_command.zig:1565`, the code was using `target_name.len` (UTF-8
byte length) instead of `encoded.len` (UTF-16 code unit length) when
calculating the total path length. This caused an index out of bounds
panic when package names contained multi-byte UTF-8 characters.

**Example scenario:**
- Package name contains character "中" (U+4E2D)
- UTF-8: 3 bytes (0xE4 0xB8 0xAD) → `target_name.len` counts as 3
- UTF-16: 1 code unit (0x4E2D) → `encoded.len` counts as 1
- Using the wrong length led to: `panic: index out of bounds: index 62,
len 60`

## Changes

- Changed line 1565 from `target_name.len` to `encoded.len`

## Test plan

- [x] Build compiles successfully
- [x] Code review confirms the fix addresses the root cause
- [ ] Windows-specific testing (if available)

Fixes the panic reported in Sentry/crash reports.

150338faab implement publicHoistPattern and hoistPattern (#23567)
### What does this PR do?
Adds support for `publicHoistPattern` in `bunfig.toml` and
`public-hoist-pattern` from `.npmrc`. This setting allows you to select
transitive packages to hoist to the root node_modules making them
available for all workspace packages.

```toml
[install]
# can be a string
publicHoistPattern = "@types*"
# or an array
publicHoistPattern = [ "@types*", "*eslint*" ]
```

`publicHoistPattern` only affects the isolated linker.

---

Adds `hoistPattern`. `hoistPattern` is the same as `publicHoistPattern`,
but applies to the `node_modules/.bun/node_modules` directory instead of
the root node_modules. Also the default value of `hoistPattern` is `*`
(everything is hoisted to `node_modules/.bun/node_modules` by default).

---

Fixes a determinism issue constructing the
`node_modules/.bun/node_modules` directory.

---

closes #23481
closes #6160
closes #23548
### How did you verify your code works?
Added tests for
- [x] only include patterns
- [x] only exclude patterns
- [x] mix of include and exclude
- [x] errors for unexpected expression types
- [x] excluding direct dependency (should still include)
- [x] match all with `*`
- [x] string and array expression types

3e53ada574 Fix assertion failure when using --production flag (#23821)
Fixes #19652

## Summary

Fixes a crash that occurred when using the `--production` flag with `bun
build`, particularly on Windows where assertions are enabled in release
builds.

## Root Cause

The crash occurred because an assertion for `jsx.development` was
running **before** `jsx.development` was properly configured. The
problematic sequence was:

1. Set `NODE_ENV=production` in env map
2. Call `configureDefines()` which reads `NODE_ENV` and calls
`setProduction(true)`, setting `jsx.development=false`
3.  **Assert `jsx.development` is false** (assertion fired here, before
line 203 below)
4. Set `jsx.development = !production` on line 203 (too late)

## Changes

This PR reorders the code to move the assertion **after**
`jsx.development` is properly set:

1. Set both `BUN_ENV` and `NODE_ENV` to `"production"` in env map
2. Call `configureDefines()` 
3. Set `jsx.development = !production` (now happens first)
4.  **Assert `jsx.development` is false** (now runs after it's set)

Also adds `BUN_ENV=production` to match the behavior of setting
`NODE_ENV`.

## Test Plan

Added regression test in `test/regression/issue/19652.test.ts` that
verifies `bun build --production` doesn't crash.

The test:
-  Passes on this branch
-  Would fail on main (assertion failure)

3921f76ff8 Add --only-failures flag to bun:test (#23312)
## Summary

Adds a new `--only-failures` flag to `bun test` that only displays test
failures, similar to `--dots` but without printing dots for each test.

## Motivation

When running large test suites or in CI environments, users often only
care about test failures. The existing `--dots` reporter reduces
verbosity by showing dots, but still requires visual scanning to find
failures. The `--only-failures` flag provides a cleaner output by
completely suppressing passing tests.

## Changes

- Added `--only-failures` CLI flag in `Arguments.zig`
- Added `only_failures` boolean to the test reporters struct in
`cli.zig`
- Updated test output logic in `test_command.zig` to skip non-failures
when flag is set
- Updated `jest.zig` and `bun_test.zig` to handle the new flag
- Added comprehensive tests in `only-failures.test.ts`

## Usage

```bash
bun test --only-failures
```

Example output (only shows failures):
```
test/example.test.ts:
(fail) failing test
error: expect(received).toBe(expected)

Expected: 3
Received: 2

5 pass
1 skip
2 fail
Ran 8 tests across 1 file.
```

## Test Plan

- Verified `--only-failures` flag only shows failing tests
- Verified normal test output still works without the flag
- Verified `--dots` reporter still works correctly
- Added regression tests with snapshot comparisons

74fa49963c Fix: Error when using bun build --no-bundle with HTML entrypoint (#23572)
Fixes #23569

## Summary

HTML imports require bundling to work correctly, as they need to process
and transform linked assets (JS/CSS). When `--no-bundle` is used, no
bundling or transformation happens, which causes a crash.

This change adds validation to detect HTML entrypoints when
`--no-bundle` is used and provides a clear error message explaining that
"HTML imports are only supported when bundling".

## Changes

- Added validation in `src/cli/build_command.zig` to check for HTML
entrypoints when `--no-bundle` flag is used
- Shows clear error message: "HTML imports are only supported when
bundling"
- Added regression tests in `test/regression/issue/23569.test.ts`

## Test Plan

### Before
```bash
$ bun build ./index.html --no-bundle
# Crashes without helpful error
```

### After
```bash
$ bun build ./index.html --no-bundle
error: HTML imports are only supported when bundling
```

### Tests
-  Test with `--no-bundle` flag errors correctly
-  Test with `--no-bundle --outdir` errors correctly  
-  Test without `--no-bundle` works normally
-  All 3 regression tests pass

642d04b9f2 Add --pass-with-no-tests flag to test runner (#23424)
## Summary

This PR adds support for the `--pass-with-no-tests` CLI flag to the test
runner, addressing issue #20814.

With the latest v1.2.8 release, the test runner now fails when no tests
match a filter. While this is useful for agentic coding workflows, there
are legitimate cases where the previous behavior is preferred, such as
in monorepos where a standard test file pattern is used as a filter but
not all packages contain tests.

This flag makes the test runner behave like Jest and Vitest, exiting
with code 0 when no tests are found.

## Changes

- Added `--pass-with-no-tests` flag to CLI arguments in
`src/cli/Arguments.zig`
- Added `pass_with_no_tests` field to `TestOptions` struct in
`src/cli.zig`
- Updated test runner logic in `src/cli/test_command.zig` to respect the
flag
- Added comprehensive tests in
`test/cli/test/pass-with-no-tests.test.ts`

## Test Plan

All new tests pass:
-  `--pass-with-no-tests` exits with 0 when no test files found
-  `--pass-with-no-tests` exits with 0 when filters match no tests
-  Without flag, still exits with 1 when no tests found (preserves
existing behavior)
-  `--pass-with-no-tests` still fails when actual tests fail

Closes #20814

bad726f943 fix(watcher): handle vim atomic save race on macOS (#23566)
## Summary

Fixes a race condition on macOS where editing the entrypoint with vim's
atomic save causes "Module not found" errors during hot reload.

## Root Cause

On macOS, kqueue watches file descriptors/inodes, not paths. Vim's
atomic save sequence:
1. Rename `a.js` to `a.js~` → kqueue reports `NOTE_RENAME` on watched fd
2. Hot reloader immediately triggers reload
3. New file hasn't been created yet → `ENOENT` error
4. Vim re-creates `a.js`, and writes file contents into it
5. Directory gets `NOTE_WRITE` but file already removed from watchlist

```
rename("a.js", "a.js~")                 = 0
openat(AT_FDCWD, "a.js", O_WRONLY|O_CREAT, 0664) = 3
ftruncate(3, 0)                         = 0
write(3, "foobar\n", 7)                 = 7
close(3)                                = 0
```

This is macOS-specific because:
- **kqueue**: watches inodes, fd becomes stale when inode deleted
- **inotify (Linux)**: watches paths, gets `IN.MOVED_TO` (not
`IN.MOVE_SELF`), so files stay in watchlist

## Solution

When the entrypoint receives `NOTE_RENAME` on macOS:
1. Set `is_waiting_for_dir_change` flag
2. Skip immediate reload
3. Wait for parent directory `NOTE_WRITE` event
4. Use `faccessat()` to verify file exists
5. Trigger reload

This only applies to the entrypoint because dependencies have buffering
time during import graph traversal.

## Test Plan

Manual testing with vim on macOS:
1. Run `bun --hot entrypoint.js`
2. Edit entrypoint with vim (`:w`)
3. Verify no "Module not found" errors
4. Verify hot reload succeeds

Adds back the `--only` flag. When running `bun test` on a full test

will run all other tests from other files. With this flag, it will not
run things from other files.

767e03ef24 load local bunfig.toml for bun run earlier (for run.bun option) (#16664)
Alternative to #15596 where it now only impacts `bun run` for the same
cwd dir. This does not effect `bunx` ([even though according to code it
should load
it](7830e15650/src/cli.zig (L2597-L2628))),
and isnt as fancy as `bun install` where it ensures to check the bunfig
in `package.json` dir.

This shouldn't have any performance issues because its already loading
the file, but now its loading earlier so it can use `run.bun` option.

0b7aed1d0d fix(test): remove quotes from string variables in test.each (#23244)
## Summary
Fixes #23206

When using `test.each` with object syntax and `$variable` interpolation,
string values were being quoted (e.g., `"apple"` instead of `apple`).
This didn't match the behavior of `%s` formatting or Jest's behavior.

## Changes
- Modified `formatLabel` in `src/bun.js/test/jest.zig` to check if the
value is a primitive string and use `toString()` instead of the
formatter with `quote_strings=true`
- Added regression test in `test/regression/issue/23206.test.ts`

## Example

**Before:**
```
test.each([
  { name: "apple" },
  { name: "banana" }
])("fruit #%# is $name", fruit => {
  // Test names were:
  // "fruit #0 is "apple""
  // "fruit #1 is "banana""
});
```

**After:**
```
test.each([
  { name: "apple" },
  { name: "banana" }
])("fruit #%# is $name", fruit => {
  // Test names are now:
  // "fruit #0 is apple"
  // "fruit #1 is banana"
});
```

## Test plan
- [x] Added regression test that verifies both `%s` and `$name` syntax
produce consistent output
- [x] Tested with `AGENT=0` - all tests pass
- [x] Verified other primitive types (numbers, booleans) still format
correctly
- [x] Verified complex objects still use proper formatting

This matches Jest's behavior after their fix:

f7da0ac6fd bun install: support for minimumReleaseAge (#22801)
### What does this PR do?

fixes #22679

* 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)


| install error with no recent version | bun outdated respecting the
rule |

f0295ce0a5 Fix bunfig.toml parsing with UTF-8 BOM (#23276)
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]
```

624911180f fix(outdated): show catalog info without requiring --filter or -r (#23039)
## Summary

The `bun outdated` command now displays catalog dependencies with their
workspace grouping even when run without the `--filter` or `-r` flags.

## What changed

- Added detection for catalog dependencies in the outdated packages list
- The workspace column is now shown when:
  - Using `--filter` or `-r` flags (existing behavior) 
  - OR when there are catalog dependencies to display (new behavior)
- When there are no catalog dependencies and no filtering, the workspace
column remains hidden as before

## Why

Previously, running `bun outdated` without any flags would not show
which workspaces were using catalog dependencies, making it unclear
where catalog entries were being used. This fix ensures catalog
dependencies are properly grouped and displayed with their workspace
information.

## Test

```bash
# Create a workspace project with catalog dependencies
mkdir test-catalog && cd test-catalog
cat > package.json << 'JSON'
{
  "name": "test-catalog",
  "workspaces": ["packages/*"],
  "catalog": {
    "react": "^17.0.0"
  }
}
JSON

mkdir -p packages/{app1,app2}
echo '{"name":"app1","dependencies":{"react":"catalog:"}}' > packages/app1/package.json
echo '{"name":"app2","dependencies":{"react":"catalog:"}}' > packages/app2/package.json

bun install
bun outdated  # Should now show catalog grouping without needing --filter
```

c5005a37d7 Fix --tolerate-republish flag in bun publish (continues PR #22107) (#22381)
## 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

be15f6c80c feat(test): add --randomize flag to run tests in random order (#22945)
## Summary

This PR adds a `--randomize` flag to `bun test` that shuffles test
execution order. This helps developers catch test interdependencies and
identify flaky tests that may depend on execution order.

## Changes

-  Added `--randomize` CLI flag to test command
- 🔀 Implemented test shuffling using `bun.fastRandom()` as PRNG seed
- 🧪 Added comprehensive tests to verify randomization behavior
- 📝 Tests are shuffled at the scheduling phase, properly handling
describe blocks and hooks

## Usage

```bash
# Run tests in random order
bun test --randomize

# Works with other test flags
bun test --randomize --bail
bun test mytest.test.ts --randomize
```

## Implementation Details

The randomization happens in `Order.zig`'s `generateOrderDescribe`
function, which shuffles the `current.entries.items` array when the
randomize flag is set. This ensures:

- All tests still run (just in different order)
- Hooks (beforeAll, afterAll, beforeEach, afterEach) maintain proper
relationships
- Describe blocks and their children are shuffled independently
- Each run uses a different random seed for varied execution orders

## Test Coverage

Added tests in `test/cli/test/test-randomize.test.ts` that verify:
- Tests run in random order with the flag
- All tests execute (none are skipped)
- Without the flag, tests run in consistent order
- Randomization works with describe blocks

## Example Output

```bash
# Without --randomize (consistent order)
$ bun test mytest.js
Running test 1
Running test 2
Running test 3
Running test 4
Running test 5

# With --randomize (different order each run)
$ bun test mytest.js --randomize
Running test 3
Running test 5
Running test 1
Running test 4
Running test 2

$ bun test mytest.js --randomize
Running test 2
Running test 4
Running test 5
Running test 1
Running test 3
```

e58a4a7282 feat: add concurrent-test-glob option to bunfig.toml for selective concurrent test execution (#22898)
## Summary

Adds a new `concurrentTestGlob` configuration option to bunfig.toml that
allows test files matching a glob pattern to automatically run with
concurrent test execution enabled. This provides granular control over
which tests run concurrently without modifying test files or using the
global `--concurrent` flag.

## Problem

Currently, enabling concurrent test execution in Bun requires either:
1. Using the `--concurrent` flag (affects ALL tests)
2. Manually adding `test.concurrent()` to individual test functions
(requires modifying test files)

This creates challenges for:
- Large codebases wanting to gradually migrate to concurrent testing
- Projects with mixed test types (unit tests that need isolation vs
integration tests that can run in parallel)
- CI/CD pipelines that want to optimize test execution without code
changes

## Solution

This PR introduces a `concurrentTestGlob` option in bunfig.toml that
automatically enables concurrent execution for test files matching a
specified glob pattern:

```toml
[test]
concurrentTestGlob = "**/concurrent-*.test.ts"
```

### Key Features
-  Non-breaking: Completely opt-in via configuration
-  Flexible: Use glob patterns to target specific test files or
directories
-  Override-friendly: `--concurrent` flag still forces all tests to run
concurrently
-  Zero code changes: No need to modify existing test files

## Implementation Details

### Code Changes
1. Added `concurrent_test_glob` field to `TestOptions` struct
(`src/cli.zig`)
2. Added parsing for `concurrentTestGlob` from bunfig.toml
(`src/bunfig.zig`)
3. Added `concurrent_test_glob` field to `TestRunner`
(`src/bun.js/test/jest.zig`)
4. Implemented `shouldFileRunConcurrently()` method that checks file
paths against the glob pattern
5. Updated test execution logic to apply concurrent mode based on glob
matching (`src/bun.js/test/ScopeFunctions.zig`)

### How It Works
- When a test file is loaded, its path is checked against the configured
glob pattern
- If it matches, all tests in that file run concurrently (as if
`--concurrent` was passed)
- Files not matching the pattern run sequentially as normal
- The `--concurrent` CLI flag overrides this behavior when specified

## Usage Examples

### Basic Usage
```toml
# bunfig.toml
[test]
concurrentTestGlob = "**/integration/*.test.ts"
```

### Multiple Patterns
```toml
[test]
concurrentTestGlob = [
  "**/integration/*.test.ts",
  "**/e2e/*.test.ts", 
  "**/concurrent-*.test.ts"
]
```

### Migration Strategy
Teams can gradually migrate to concurrent testing:
1. Start with integration tests: `"**/integration/*.test.ts"`
2. Add stable unit tests: `"**/fast-*.test.ts"`
3. Eventually migrate most tests except those requiring isolation

## Testing

Added comprehensive test coverage in
`test/cli/test/concurrent-test-glob.test.ts`:
-  Tests matching glob patterns run concurrently (verified via
execution order logging)
-  Tests not matching patterns run sequentially (verified via shared
state and execution order)
-  `--concurrent` flag properly overrides the glob setting
- Tests use file system logging to deterministically verify concurrent
vs sequential execution

## Documentation

Complete documentation added:
- `docs/runtime/bunfig.md` - Configuration reference
- `docs/test/configuration.md` - Test configuration details
- `docs/test/examples/concurrent-test-glob.md` - Comprehensive example
with migration guide

## Performance Considerations

- Glob matching happens once per test file during loading
- Uses Bun's existing `glob.match()` implementation
- Minimal overhead: simple string pattern matching
- Future optimization: Could cache match results per file path

## Breaking Changes

None. This is a fully backward-compatible, opt-in feature.

## Checklist

- [x] Implementation complete and building
- [x] Tests passing
- [x] Documentation updated
- [x] No breaking changes
- [x] Follows existing code patterns

## Related Issues

This addresses common requests for more granular control over concurrent
test execution, particularly for large codebases migrating from other
test runners.

Fixes #5585, Fixes #9548, Might fix 5996

# New features:

## Concurrent tests

Concurrent tests allow running multiple async tests at the same time.

```ts
// concurrent.test.ts
test.concurrent("this takes a while 1", async () => {
  await Bun.sleep(1000);
});
test.concurrent("this takes a while 2", async () => {
  await Bun.sleep(1000);
});
test.concurrent("this takes a while 3", async () => {
  await Bun.sleep(1000);
});
```

Without `.concurrent`, this test file takes 3 seconds to run because
each one has to wait for the one before it to finish before it can
start.

With `.concurrent`, this file takes 1 second because all three sleeps
can run at once.

```
$> bun-after test concurrent
concurrent.test.js:
✓ this takes a while 1 [1005.36ms]
✓ this takes a while 2 [1012.51ms]
✓ this takes a while 3 [1013.15ms]

 3 pass
 0 fail
Ran 3 tests across 1 file. [1081.00ms]
```

To run all tests as concurrent, pass the `--concurrent` flag when
running tests.

Limitations:

- concurrent tests cannot attribute `expect()` call counts to the test,
meaning `expect.assertions()` does not function
- concurrent tests cannot use `toMatchSnapshot`. `toMatchInlineSnapshot`
is still supported.
- `beforeAll`/`afterAll` will never be executed concurrently.
`beforeEach`/`afterEach` will.

## Chaining

Chaining multiple describe/test qualifiers is now allowed. Previously,
it would fail.

```ts
// chaining-test-qualifiers.test.ts
test.failing.each([1, 2, 3])("each %i", async i => {
  throw new Error(i);
});
```

```
$> bun-after test chaining-test-qualifiers
a.test.js:
✓ each 1
✓ each 2
✓ each 3
```

# Breaking changes:

## Describe ordering

Previously, describe callbacks were called immediately. Now, they are
deferred until the outer callback has finished running. The previous
order matched Jest. The new order is similar to Vitest, but does not
match exactly.

```ts
// describe-ordering.test.ts
describe("outer", () => {
  console.log("outer before");
  describe("inner", () => {
    console.log("inner");
  });
  console.log("outer after");
});
```

Before, this would print

```
$> bun-before test describe-ordering
outer before
inner
outer after
```

Now, this will print

```
$> bun-after test describe-ordering
outer before
outer after
inner
```

## Test ordering

Describes are no longer always called before tests. They are now in
order.

```ts
// test-ordering.test.ts
test("one", () => {});
describe("scope", () => {
  test("two", () => {});
});
test("three", () => {});
```

Before, this would print

```
$> bun-before test test-ordering
✓ scope > two
✓ one
✓ three
```

Now, this will print

```
$> bun-after test test-ordering
✓ one
✓ scope > two
✓ three
```

## Preload hooks

Previously, beforeAll in a preload ran before the first file and
afterAll ran after the last file. Now, beforeAll will run at the start
of each file and afterAll will run at the end of each file. This
behaviour matches Jest and Vitest.

```ts
// preload.ts
beforeAll(() => console.log("preload: beforeAll"));
afterAll(() => console.log("preload: afterAll"));
```

```ts
// preload-ordering-1.test.ts
test("demonstration file 1", () => {});
```

```ts
// preload-ordering-2.test.ts
test("demonstration file 2", () => {});
```

```
$> bun-before test --preload=./preload preload-ordering
preload-ordering-1.test.ts:
preload: beforeAll
✓ demonstration file 1

preload-ordering-2.test.ts:
✓ demonstration file 2
preload: afterAll
```

```
$> bun-after test --preload=./preload preload-ordering
preload-ordering-1.test.ts:
preload: beforeAll
✓ demonstration file 1
preload: afterAll

preload-ordering-2.test.ts:
preload: beforeAll
✓ demonstration file 2
preload: afterAll
```

## Describe failures

Current behaviour is that when an error is thrown inside a describe
callback, none of the tests declared there will run. Now, describes
declared inside will also not run. The new behaviour matches the
behaviour of Jest and Vitest.

```ts
// describe-failures.test.ts
describe("erroring describe", () => {
  test("this test does not run because its describe failed", () => {
    expect(true).toBe(true);
  });
  describe("inner describe", () => {
    console.log("does the inner describe callback get called?");
    test("does the inner test run?", () => {
      expect(true).toBe(true);
    });
  });
  throw new Error("uh oh!");
});
```

Before, the inner describe callback would be called and the inner test
would run, although the outer test would not:

```
$> bun-before test describe-failures
describe-failures.test.ts:
does the inner describe callback get called?

# Unhandled error between tests
-------------------------------
11 |   throw new Error("uh oh!");
             ^
error: uh oh!
-------------------------------

✓ erroring describe > inner describe > does the inner test run?

 1 pass
 0 fail
 1 error
 1 expect() calls
Ran 1 test across 1 file.
Exited with code [1]
```

Now, the inner describe callback is not called at all.

```
$> bun-after test describe-failures
describe-failures.test.ts:

# Unhandled error between tests
-------------------------------
11 |   throw new Error("uh oh!");
             ^
error: uh oh!
-------------------------------


 0 pass
 0 fail
 1 error
Ran 0 tests across 1 file.
Exited with code [1]
```

## Hook failures

Previously, a beforeAll failure would skip subsequent beforeAll()s, the
test, and the afterAll. Now, a beforeAll failure skips any subsequent
beforeAll()s and the test, but not the afterAll.

```js
beforeAll(() => {
  throw new Error("before all: uh oh!");
});
test("my test", () => {
  console.log("my test");
});
afterAll(() => console.log("after all"));
```

```
$> bun-before test hook-failures
Error: before all: uh oh!

$> bun-after test hook-failures
Error: before all: uh oh!
after all
```

Previously, an async beforeEach failure would still allow the test to
run. Now, an async beforeEach failure will prevent the test from running

```js
beforeEach(() => {
  await 0;
  throw "uh oh!";
});
it("the test", async () => {
  console.log("does the test run?");
});
```

```
$> bun-before test async-beforeeach-failure
does the test run?
error: uh oh!
uh oh!
✗ the test

$> bun-after test async-beforeeach-failure
error: uh oh!
uh oh!
✗ the test
```

## Hook timeouts

Hooks will now time out, and can have their timeout configured in an
options parameter

```js
beforeAll(async () => {
  await Bun.sleep(1000);
}, 500);
test("my test", () => {
  console.log("ran my test");
});
```

```
$> bun-before test hook-timeouts
ran my test
Ran 1 test across 1 file. [1011.00ms]

$> bun-after test hook-timeouts
✗ my test [501.15ms]
  ^ a beforeEach/afterEach hook timed out for this test.
```

## Hook execution order

beforeAll will now execute before the tests in the scope, rather than
immediately when it is called.

```ts
describe("d1", () => {
  beforeAll(() => {
    console.log("<d1>");
  });
  test("test", () => {
    console.log("  test");
  });
  afterAll(() => {
    console.log("</d1>");
  });
});
describe("d2", () => {
  beforeAll(() => {
    console.log("<d2>");
  });
  test("test", () => {
    console.log("  test");
  });
  afterAll(() => {
    console.log("</d2>");
  });
});
```

```
$> bun-before test ./beforeall-ordering.test.ts
<d1>
<d2>
  test
</d1>
  test
</d2>

$> bun-after test ./beforeall-ordering.test.ts
<d1>
  test
</d1>
<d2>
  test
</d2>
```

## test inside test

test() inside test() now errors rather than silently failing. Support
for this may be added in the future.

```ts
test("outer", () => {
    console.log("outer");
    test("inner", () => {
        console.log("inner");
    });
});
```

```
$> bun-before test
outer
✓ outer [0.06ms]

 1 pass
 0 fail
Ran 1 test across 1 file. [8.00ms]

$> bun-after test
outer
1 | test("outer", () => {
2 |     console.log("outer");
3 |     test("inner", () => {
        ^
error: Cannot call test() inside a test. Call it inside describe() instead.
✗ outer [0.71ms]

 0 pass
 1 fail
```

## afterAll inside test

afterAll inside a test is no longer allowed

```ts
test("test 1", () => {
  afterAll(() => console.log("afterAll"));
  console.log("test 1");
});
test("test 2", () => {
  console.log("test 2");
});
```

```
$> bun-before
test 1
✓ test 1 [0.05ms]
test 2
✓ test 2
afterAll

$> bun-after
error: Cannot call afterAll() inside a test. Call it inside describe() instead.
✗ test 1 [1.00ms]
test 2
✓ test 2 [0.20ms]
```

# Only inside only

Previously, an outer 'describe.only' would run all tests inside it even
if there was an inner 'test.only'. Now, only the innermost only tests
are executed.

```ts
describe.only("outer", () => {
    test("one", () => console.log("should not run"));
    test.only("two", () => console.log("should run"));
});
```

```
$> bun-before test
should not run
should run

$> bun-after test
should run
```

With no inner only, the outer only will still run all tests:

```ts
describe.only("outer", () => {
    test("test 1", () => console.log("test 1 runs"));
    test("test 2", () => console.log("test 2 runs"));
});
```

# Potential follow-up work

- [ ] for concurrent tests, display headers before console.log messages
saying which test it is for
  - this will need async context or similar
- refActiveExecutionEntry should also be able to know the current test
even in test.concurrent
- [ ] `test("rerun me", () => { console.log("run one time!"); });`
`--rerun-each=3` <- this runs the first and third time but not the
second time. fix.
- [ ] should to cache the JSValue created from
DoneCallback.callAsFunction
- [ ] implement retry and rerun params for tests.
- [ ] Remove finalizer on ScopeFunctions.zig by storing the data in 3
jsvalues passed in bind rather than using a custom class. We should also
migrate off of the ClassGenerator for ScopeFunctions
- [ ] support concurrent limit, how many concurrent tests are allowed to
run at a time. ie `--concurrent-limit=25`
- [ ] flag to run tests in random order
- [ ] `test.failing` should have its own style in the same way
`test.todo` passing marks as 'todo' insetead of 'passing'. right now
it's `✓` which is confusing.
- [ ] remove all instances of bun.jsc.Jest.Jest.current
  - [ ] test options should be in BunTestRoot
- [ ] we will need one global still, stored in the globalobject/vm/?.
but it should not be a Jest instance.
- [ ] consider allowing test() inside test(), as well as afterEach and
afterAll. could even allow describe() too. to do this we would switch
from indices to pointers and they would be in a linked list. they would
be allocated in memorypools for perf/locality. some special
consideration is needed for making sure repeated tests lose their
temporary items. this could also improve memory usage soomewhat.
- [ ] consider using a jsc Bound Function rather than CallbackWithArgs.
bound functions allow adding arguments and they are only one value for
GC instead of many. and this removes our unnecessary three copies.
- [ ] eliminate Strong.Safe. we should be using a C++ class instead.
- [ ] consider modifying the junit reporter to print the whole describe
tree at the end instead of trying to output as test results come in. and
move it into its own file.
- [ ] expect_call_count/expect_assertions is confusing. rename to
`expect_calls`, `assert_expect_calls`. or something.
- [ ] Should make line_no be an enum with a none option and a function
to get if line nombers are enabled
- [ ] looks like we don't need to use file_id anymore (remove
`bun.jsc.Jest.Jest.runner.?.getOrPutFile(file_path).file_id;`, store the
file path directly)
- [ ] 'dot' test reporter like vitest?
- [ ] `test.failing.if(false)` errors because it can't replace mode
'failing' with mode 'skip'. this should probably be allowed instead.
- [ ] trigger timeout termination exception for `while(true) {}`
- [ ] clean up unused callbacks. as soon as we advance to the next
execution group, we can fully clean out the previous one. sometimes
within an execution sequence we can do the same.
  - clean by swapping held values with undefined
- [ ] structure cache for performance for donecallback/scopefunctions
- [ ] consider migrating CallbackWithArgs to be a bound function. the
length of the bound function can exclude the specified args.
- [ ] setting both result and maybe_skip is not ideal, maybe there
should be a function to do both at once?
- [ ] try using a linked list rather than arraylist for describe/test
children, see how it affects performance
- [ ] consider a memory pool for describescope/executionentry. test if
it improves performance.
- [ ] consider making RefDataValue methods return the reason for failure
rather than ?value. that way we can improve error messages. the reason
could be a string or it could be a defined error set
- [ ] instead of 'description orelse (unnamed)', let's have description
default to 'unnamed' and not free it if it === the global that defines
that
- [ ] Add a phase before ordering results that inherits properties to
the parents. (eg inherit only from the child and inherit has_callback
from the child. and has_callback can be on describe/test individually
rather than on base). then we won't have that happening in an init()
function (terrible!)
- [ ] this test was incidentally passing because resolves.pass() wasn't
waiting for promise
  ```
  test("fetching with Request object - issue #1527", async () => {
    const server = createServer((req, res) => {
      res.end();
    }).listen(0);
    try {
      await once(server, "listening");

      const body = JSON.stringify({ foo: "bar" });
const request = new Request(`http://localhost:${server.address().port}`,
{
        method: "POST",
        body,
      });

      expect(fetch(request)).resolves.pass();
    } finally {
      server.closeAllConnections();
    }
  });
  ```
- [ ] the error "expect.assertions() is not supported in the describe
phase, in concurrent tests, between tests, or after test execution has
completed" is not very good. we should be able to identify which of
those it is and print the right error for the context
- [ ] consider: instead of storing weak pointers to BunTest, we can
instead give the instance an id and check that it is correct when
getting the current bun test instance from the ref
- [ ] auto_killer: add three layers of auto_killer:
  - preload (includes file & test)
  - file (includes test)
  - test
- that way at the end of the test, we kill the test processes. at the
end of the file, we kill the file processes. at the end of all, we kill
anything remaining.

AsyncLocalStorage

- store active_id & refdatavalue. active_id is a replacement for the
above weak pointers thing. refdatavalue is for determining which test it
is. this probably fits in 2×u64
- use for auto_killer so timeouts can kill even in concurrent tests

45760cd53c ci: instrument being able to run leaksanitizer (#21142)
tests not in `test/no-validate-leaksan.txt` will run with leaksanitizer
in CI
leaks documented in `test/leaksan.supp` will not cause a test failure

-- notes about leaksanitizer

- will not catch garbage collected objects accumulated during
long-running processes
- will not catch js objects (eg a strong held to a promise)
- will catch native calls to `malloc` not `free`d
- will catch allocations made in C, Zig, C++, libc, dependencies,
dlopen'd

a09c45396e bun whoami as alias for bun pm whoami (currently reserved) (#22613)
### What does this PR do?

Previously, 'bun whoami' showed a reservation message indicating it was
reserved for future use. This change updates the command to execute 'bun
pm whoami' directly, making it consistent with npm's behavior.

Fixes #22614

Changes:
- Route 'bun whoami' to PackageManagerCommand instead of ReservedCommand
- Update PackageManagerCommand.exec to handle direct 'whoami' invocation

### How did you verify your code works?

- Add tests to verify both 'bun whoami' and 'bun pm whoami' work
correctly

6bafe2602e 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
```
<sub>
also probably fixes #22615 and fixes #22603 and fixes #22602
</sub>
