## Summary
- Fix segmentation fault in `bun create` when using `--no-install` with
a template that has a `bun-create.postinstall` task starting with "bun "
- The bug was caused by unconditionally slicing `argv[2..]` which
created an empty array when `npm_client` was null
- Added check for `npm_client != null` before slicing
## Reproduction
```bash
# Create template with bun-create.postinstall
mkdir -p ~/.bun-create/test-template
echo '{"name":"test","bun-create":{"postinstall":"bun install"}}' > ~/.bun-create/test-template/package.json
# This would crash before the fix
bun create test-template /tmp/my-app --no-install
```
## Test plan
- [x] Verified the reproduction case crashes before the fix
- [x] Verified the reproduction case works after the fix

## Summary
- The default trusted dependencies list should only apply to packages
installed from npm
- Non-npm sources (file:, link:, git:, github:) now require explicit
trustedDependencies
- This prevents malicious packages from spoofing trusted names through
local paths or git repos
## Test plan
- [x] Added test: file: dependency named "esbuild" does NOT auto-run
postinstall scripts
- [x] Added test: file: dependency runs scripts when explicitly added to
trustedDependencies
- [x] Verified tests fail with system bun (old behavior) and pass with
new build
- [x] Build compiles successfully

## Summary
This PR introduces a new postinstall optimization system that
significantly reduces the need to run lifecycle scripts for certain
packages by intelligently handling their requirements at install time.
## Key Features
### 1. Native Binlink Optimization
When packages like `esbuild` ship platform-specific binaries as optional
dependencies, we now:
- Detect the native binlink pattern (enabled by default for `esbuild`)
- Find the matching platform-specific dependency based on target CPU/OS
- Link binaries directly from the platform-specific package (e.g.,
`@esbuild/darwin-arm64`)
- Fall back gracefully if the platform-specific package isn't found
**Result**: No postinstall scripts needed for esbuild and similar
packages.
### 2. Lifecycle Script Skipping
For packages like `sharp` that run heavy postinstall scripts:
- Skip lifecycle scripts entirely (enabled by default for `sharp`)
- Prevents downloading large binaries or compiling native code
unnecessarily
- Reduces install time and potential failures in restricted environments
## Configuration
Both features can be configured via `package.json`:
```json
{
"nativeDependencies": ["esbuild", "my-custom-package"],
"ignoreScripts": ["sharp", "another-package"]
}
```
Set to empty arrays to disable defaults:
```json
{
"nativeDependencies": [],
"ignoreScripts": []
}
```
Environment variable overrides:
- `BUN_FEATURE_FLAG_DISABLE_NATIVE_DEPENDENCY_LINKER=1` - disable native
binlink
- `BUN_FEATURE_FLAG_DISABLE_IGNORE_SCRIPTS=1` - disable script ignoring
## Implementation Details
### Core Components
- **`postinstall_optimizer.zig`**: New file containing the optimizer
logic
- `PostinstallOptimizer` enum with `native_binlink` and `ignore`
variants
- `List` type to track optimization strategies per package hash
- Defaults for `esbuild` (native binlink) and `sharp` (ignore)
- **`Bin.Linker` changes**: Extended to support separate target paths
- `target_node_modules_path`: Where to find the actual binary
- `target_package_name`: Name of the package containing the binary
- Fallback logic when native binlink optimization fails
### Modified Components
- **PackageInstaller.zig**: Checks optimizer before:
- Enqueueing lifecycle scripts
- Linking binaries (with platform-specific package resolution)
- **isolated_install/Installer.zig**: Similar checks for isolated linker
mode
- `maybeReplaceNodeModulesPath()` resolves platform-specific packages
- Retry logic without optimization on failure
- **Lockfile**: Added `postinstall_optimizer` field to persist
configuration
## Changes Included
- Updated `esbuild` from 0.21.5 to 0.25.11 (testing with latest)
- VS Code launch config updates for debugging install with new flags
- New feature flags in `env_var.zig`
## Test Plan
- [x] Existing install tests pass
- [ ] Test esbuild install without postinstall scripts running
- [ ] Test sharp install with scripts skipped
- [ ] Test custom package.json configuration
- [ ] Test fallback when platform-specific package not found
- [ ] Test feature flag overrides

### What does this PR do?
Allows optional peers to resolve to package if possible.
Optional peers aren't auto-installed, but they should still be given a
chance to resolve. If they're always left unresolved it's possible for
multiple dependencies on the same package to result in different peer
resolutions when they should be the same. For example, this bug this
could cause monorepos using elysia to have corrupt node_modules because
there might be more than one copy of elysia in `node_modules/.bun` (or
more than the expected number of copies).

## 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

### 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.

### What does this PR do?
This PR implements support for the `email` field in `.npmrc` files for
registry scope authentication. Some private registries (particularly
Nexus) require the email field to be specified in the registry
configuration alongside username/password or token authentication.
The email field can now be specified in `.npmrc` files like:
```ini
//registry.example.com/:email=user@example.com
//registry.example.com/:username=myuser
//registry.example.com/:_password=base64encodedpassword
```
### How did you verify your code works?
1. **Built Bun successfully** - Confirmed the code compiles without
errors using `bun bd --debug`
2. **Wrote comprehensive unit tests** - Added two test cases to
`test/cli/install/npmrc.test.ts`:
- Test for standalone email field parsing
- Test for email combined with username/password authentication
3. **Verified tests pass** - Ran `bun bd test
test/cli/install/npmrc.test.ts -t "email"` and confirmed both tests
pass:
```
✓ 2 pass
✓ 0 fail
✓ 6 expect() calls
```
4. **Code changes include**:
- Added `email` field to `NpmRegistry` struct in `src/api/schema.zig`
- Updated `encode()` and `decode()` methods to handle the email field
- Modified `ini.zig` to parse and store the email field from `.npmrc`
- Removed email from the unsupported options warning (certfile and
keyfile remain unsupported)
- Updated all `NpmRegistry` struct initializations to include the email
field
- Updated `loadNpmrcFromJS` test API to return the email field

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.

## Summary
This PR improves the correctness of bin linking by atomically
normalizing `\r\n` to `\n` in shebang lines when linking bins.
### Changes
- **Refactored shebang normalization in `src/install/bin.zig`**:
- Extracted logic into separate `tryNormalizeShebang` function
- Changed from in-place file modification to atomic file replacement
- Reads entire file, creates temporary file with corrected shebang, then
atomically renames
- Properly cleans up temporary files on errors
- **Added test coverage**:
- New test file `test/cli/install/shebang-normalize.test.ts` verifies
CRLF normalization works correctly
- Modified existing test in `bun-link.test.ts` to use Python script with
CRLF shebang
### Why
The previous implementation modified files in-place by seeking to the
`\r` position and overwriting with `\n`. This could potentially corrupt
files if interrupted mid-write. The new atomic approach ensures file
integrity by writing to a temporary file first, then renaming it to
replace the original.
## Test plan
- ✅ `bun bd test test/cli/install/shebang-normalize.test.ts` - passes
- ✅ Verified bins with CRLF shebangs are normalized to LF during linking
- ✅ Code compiles successfully

## Summary
During `yarn.lock` migration, OS/CPU package metadata was not being
fetched from the npm registry when missing from `yarn.lock`. This caused
packages with platform-specific requirements to not be properly marked,
potentially leading to incorrect package installation behavior.
## Changes
Updated `fetchNecessaryPackageMetadataAfterYarnOrPnpmMigration` to
conditionally fetch OS/CPU metadata:
- **For yarn.lock migration**: Fetches OS/CPU metadata from npm registry
when not present in yarn.lock (`update_os_cpu = true`)
- **For pnpm-lock.yaml migration**: Skips OS/CPU fetching since
pnpm-lock.yaml already includes this data (`update_os_cpu = false`)
### Files Modified
- `src/install/lockfile.zig` - Added comptime `update_os_cpu` parameter
and conditional logic to fetch OS/CPU metadata
- `src/install/yarn.zig` - Pass `true` to enable OS/CPU fetching for
yarn migrations
- `src/install/pnpm.zig` - Pass `false` to skip OS/CPU fetching for pnpm
migrations (already parsed from lockfile)
## Why This Approach
- `yarn.lock` format often doesn't include OS/CPU constraints, requiring
us to fetch from npm registry
- `pnpm-lock.yaml` already parses OS/CPU during migration (lines 618-621
in pnpm.zig), making additional fetching redundant
- Using a comptime parameter allows the compiler to optimize away the
unused code path
## Testing
- ✅ Debug build compiles successfully
- Tested that the function correctly updates `pkg_meta.os` and
`pkg_meta.arch` only when:
- `update_os_cpu` is `true` (yarn migration)
- Current values are `.all` (not already set)
- Package metadata is available from npm registry

## 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

### What does this PR do?
Two things:
- we weren't adding the root package to the `pkg_map`.
- `link:` dependency paths in `"snapshots"` weren't being joined with

failures
## Details
The error message format changed from:
```
error: "git clone" for "uglify" failed
```
To:
```
error: InstallFailed cloning repository for uglify
```
This appears to be due to changes in how 404s work on the bun.sh domain.

This change was missing after changing semver core numbers to use u64.

### How did you verify your code works?
Added a test for migrating a bun.lockb with most features used.
### What does this PR do?
Sometimes packages will use very large numbers exceeding max u32 for
major/minor/patch (usually patch). This pr changes each core number in
bun to u64.
Because we serialize package information to disk for the binary lockfile
and package manifests, this pr bumps the version of each. We don't need
to change anything other than the version for serialized package
manifests because they will invalidate and save the new version. For old
binary lockfiles, this pr adds logic for migrating to the new version.
Even if there are no changes, migrating will always save the new
lockfile. Unfortunately means there will be a one time invisible diff
for binary lockfile users, but this is better than installs failing to
work.

Implements `--cpu` and `--os` flags for `bun install` to filter optional
dependencies based on target architecture and operating system. This
allows developers to control which platform-specific optional
dependencies are installed.
## What Changed
### Core Implementation
- Added `--cpu` and `--os` flags to `bun install` command that accept
multiple values
- Multiple values combine with bitwise OR (e.g., `--cpu x64 --cpu arm64`
matches packages for either architecture)
- Updated `isDisabled` methods throughout the codebase to accept custom
CPU/OS targets
- Removed deprecated `isMatch` methods in favor of `isMatchWithTarget`
for consistency
### Files Modified
- `src/install/npm.zig` - Removed `isMatch` methods, standardized on
`isMatchWithTarget`
- `src/install/PackageManager/CommandLineArguments.zig` - Parse and
validate multiple flag values
- `src/install/PackageManager/PackageManagerOptions.zig` - Pass CPU/OS
options through
- `src/install/lockfile/Package.zig` & `Package/Meta.zig` - Updated
`isDisabled` signatures
- `src/install/lockfile/Tree.zig` & `lockfile.zig` - Updated call sites
## Usage Examples
```bash
# Install only x64 dependencies
bun install --cpu x64
# Install dependencies for both x64 and arm64
bun install --cpu x64 --cpu arm64
# Install Linux-specific dependencies
bun install --os linux
# Install for multiple platforms
bun install --cpu x64 --cpu arm64 --os linux --os darwin
```
## Test Plan
✅ All 10 tests pass in `test/cli/install/bun-install-cpu-os.test.ts`:
- CPU architecture filtering
- OS filtering
- Combined CPU and OS filtering
- Multiple CPU architectures support
- Multiple operating systems support
- Multiple CPU and OS combinations
- Error handling for invalid values
- Negated CPU/OS support (`!arm64`, `!linux`)
