## Summary
This PR adds a new `--compile-argv` option to `bun build --compile` that
allows developers to embed runtime arguments into standalone
executables. The specified arguments are stored in the executable
metadata during compilation and provide **dual functionality**:
1. **🔧 Actually processed by Bun runtime** (like passing them on command
line)
2. **📊 Available in `process.execArgv`** (for application inspection)
This means flags like `--user-agent`, `--smol`, `--max-memory` will
actually take effect AND be visible to your application!
## Motivation & Use Cases
### 1. **Global User Agent for Web Scraping**
Perfect for @thdxr's opencode use case - the user agent actually gets
applied:
```bash
# Compile with custom user agent that ACTUALLY works
bun build --compile --compile-argv="--user-agent='OpenCode/1.0'" ./scraper.ts --outfile=opencode
# The user agent is applied by Bun runtime AND visible in execArgv
./opencode # All HTTP requests use the custom user agent!
```
### 2. **Memory-Optimized Builds**
Create builds with actual runtime memory optimizations:
```bash
# Compile with memory optimization that ACTUALLY takes effect
bun build --compile --compile-argv="--smol --max-memory=512mb" ./app.ts --outfile=app-optimized
# Bun runtime actually runs in smol mode with memory limit
```
### 3. **Performance & Debug Builds**
Different builds with different runtime characteristics:
```bash
# Production: optimized for memory
bun build --compile --compile-argv="--smol --gc-frequency=high" ./app.ts --outfile=app-prod
# Debug: with inspector enabled
bun build --compile --compile-argv="--inspect=0.0.0.0:9229" ./app.ts --outfile=app-debug
```
### 4. **Security & Network Configuration**
Embed security settings that actually apply:
```bash
# TLS and network settings that work
bun build --compile --compile-argv="--tls-min-version=1.3 --dns-timeout=5000" ./secure-app.ts
```
## How It Works
### Dual Processing Architecture
The implementation provides both behaviors:
```bash
# Compiled with: --compile-argv="--smol --user-agent=Bot/1.0"
./my-app --config=prod.json
```
**What happens:**
1. **🔧 Runtime Processing**: Bun processes `--smol` and
`--user-agent=Bot/1.0` as if passed on command line
2. **📊 Application Access**: Your app can inspect these via
`process.execArgv`
```javascript
// In your compiled application:
// 1. The flags actually took effect:
// - Bun is running in smol mode (--smol processed)
// - All HTTP requests use Bot/1.0 user agent (--user-agent processed)
// 2. You can also inspect what flags were used:
console.log(process.execArgv); // ["--smol", "--user-agent=Bot/1.0"]
console.log(process.argv); // ["./my-app", "--config=prod.json"]
// 3. Your application logic can adapt:
if (process.execArgv.includes("--smol")) {
console.log("Running in memory-optimized mode");
}
```
### Implementation Details
1. **Build Time**: Arguments stored in executable metadata
2. **Runtime Startup**:
- Arguments prepended to actual argv processing (so Bun processes them)
- Arguments also populate `process.execArgv` (so app can inspect them)
3. **Result**: Flags work as if passed on command line + visible to
application
## Example Usage
```bash
# User agent that actually works
bun build --compile --compile-argv="--user-agent='MyBot/1.0'" ./scraper.ts --outfile=scraper
# Memory optimization that actually applies
bun build --compile --compile-argv="--smol --max-memory=256mb" ./microservice.ts --outfile=micro
# Debug build with working inspector
bun build --compile --compile-argv="--inspect=127.0.0.1:9229" ./app.ts --outfile=app-debug
# Multiple working flags
bun build --compile --compile-argv="--smol --user-agent=Bot/1.0 --tls-min-version=1.3" ./secure-scraper.ts
```
## Runtime Verification
```javascript
// Check what runtime flags are active
const hasSmol = process.execArgv.includes("--smol");
const userAgent = process.execArgv.find(arg => arg.startsWith("--user-agent="))?.split("=")[1];
const maxMemory = process.execArgv.find(arg => arg.startsWith("--max-memory="))?.split("=")[1];
console.log("Memory optimized:", hasSmol);
console.log("User agent:", userAgent);
console.log("Memory limit:", maxMemory);
// These flags also actually took effect in the runtime!
```
## Changes Made
### Core Implementation
- **Arguments.zig**: Added `--compile-argv <STR>` flag with validation
- **StandaloneModuleGraph.zig**: Serialization/deserialization for
`compile_argv`
- **build_command.zig**: Pass `compile_argv` to module graph
- **cli.zig**: **Prepend arguments to actual argv processing** (so Bun
processes them)
- **node_process.zig**: **Populate `process.execArgv`** from stored
arguments
- **bun.zig**: Made `appendOptionsEnv()` public for reuse
### Testing
- **expectBundled.ts**: Added `compileArgv` test support
- **compile-argv.test.ts**: Tests verifying dual behavior
## Behavior
### Complete Dual Functionality
```javascript
// With --compile-argv="--smol --user-agent=TestBot/1.0":
// ✅ Runtime flags actually processed by Bun:
// - Memory usage optimized (--smol effect)
// - HTTP requests use TestBot/1.0 user agent (--user-agent effect)
// ✅ Flags visible to application:
process.execArgv // ["--smol", "--user-agent=TestBot/1.0"]
process.argv // ["./app", ...script-args] (unchanged)
```
## Backward Compatibility
- ✅ Purely additive feature - no breaking changes
- ✅ Optional flag - existing behavior unchanged when not used
- ✅ No impact on non-compile builds
## Perfect for @thdxr's Use Case!
```bash
# Compile opencode with working user agent
bun build --compile --compile-argv="--user-agent='OpenCode/1.0'" ./opencode.ts --outfile=opencode
# Results in:
# 1. All HTTP requests actually use OpenCode/1.0 user agent ✨
# 2. process.execArgv contains ["--user-agent=OpenCode/1.0"] for inspection ✨
```
The user agent will actually work in all HTTP requests made by the
compiled executable, not just be visible as metadata!

## Summary
Fixes a prerequisite issue in #21792 where `Bun.serve()` incorrectly
rejected TLS arrays with exactly 1 object.
The original issue reports a WebSocket crash with multiple TLS configs,
but users first encounter this validation bug that prevents
single-element TLS arrays from working at all.
## Root Cause
The bug was in `ServerConfig.zig:918` where the condition checked for
exactly 1 element and threw an error:
```zig
if (value_iter.len == 1) {
return global.throwInvalidArguments("tls option expects at least 1 tls object", .{});
}
```
This prevented users from using the syntax: `tls: [{ cert, key,
serverName }]`
## Fix
Updated the validation logic to:
- Empty TLS arrays are ignored (treated as no TLS)
- Single-element TLS arrays work correctly for SNI
- Multi-element TLS arrays continue to work as before
```zig
if (value_iter.len == 0) {
// Empty TLS array means no TLS - this is valid
} else {
// Process the TLS configs...
}
```
## Testing
- ✅ All existing SSL tests still pass (16/16)
- ✅ New comprehensive regression test with 7 test cases
- ✅ Tests cover empty arrays, single configs, multiple configs, and
error cases
## Note
This fix addresses the validation issue that prevents users from
reaching the deeper WebSocket SNI crash mentioned in #21792. The crash
itself may require additional investigation, but this fix resolves the
immediate blocker that users encounter first.

# Fix NAPI cleanup hook behavior to match Node.js
This PR addresses critical differences in NAPI cleanup hook
implementation that cause crashes when native modules attempt to remove
cleanup hooks. The fixes ensure Bun's behavior matches Node.js exactly.
## Issues Fixed
Fixes#20835Fixes#18827Fixes#21392Fixes#21682Fixes#13253
All these issues show crashes related to NAPI cleanup hook management:
- #20835, #18827, #21392, #21682: Show "Attempted to remove a NAPI
environment cleanup hook that had never been added" crashes with
`napi_remove_env_cleanup_hook`
- #13253: Shows `napi_remove_async_cleanup_hook` crashes in the stack
trace during Vite dev server cleanup
## Key Behavioral Differences Addressed
### 1. Error Handling for Non-existent Hook Removal
- **Node.js**: Silently ignores removal of non-existent hooks (see
`node/src/cleanup_queue-inl.h:27-30`)
- **Bun Before**: Crashes with `NAPI_PERISH` error
- **Bun After**: Silently ignores, matching Node.js behavior
### 2. Duplicate Hook Prevention
- **Node.js**: Uses `CHECK_EQ` which crashes in ALL builds when adding
duplicate hooks (see `node/src/cleanup_queue-inl.h:24`)
- **Bun Before**: Used debug-only assertions
- **Bun After**: Uses `NAPI_RELEASE_ASSERT` to crash in all builds,
matching Node.js
### 3. VM Termination Checks
- **Node.js**: No VM termination checks in cleanup hook APIs
- **Bun Before**: Had VM termination checks that could cause spurious
failures
- **Bun After**: Removed VM termination checks to match Node.js
### 4. Async Cleanup Hook Handle Validation
- **Node.js**: Validates handle is not NULL before processing
- **Bun Before**: Missing NULL handle validation
- **Bun After**: Added proper NULL handle validation with
`napi_invalid_arg` return
## Execution Order Verified
Both Bun and Node.js execute cleanup hooks in LIFO order (Last In, First
Out) as expected.
## Additional Architectural Differences Identified
Two major architectural differences remain that affect compatibility but
don't cause crashes:
1. **Queue Architecture**: Node.js uses a single unified queue for all
cleanup hooks, while Bun uses separate queues for regular vs async
cleanup hooks
2. **Iteration Safety**: Different behavior when hooks are added/removed
during cleanup iteration
These will be addressed in future work as they require more extensive
architectural changes.
## Testing
- Added comprehensive test suite covering all cleanup hook scenarios
- Tests verify identical behavior between Bun and Node.js
- Includes edge cases like duplicate hooks, non-existent removal, and
execution order
- All tests pass with the current fixes
The changes ensure NAPI modules using cleanup hooks (like LMDB, native
Rust modules, etc.) work reliably without crashes.

## 🐛 Problem
Fixes#21907 - CSS parser was crashing with "integer part of floating
point value out of bounds" when processing extremely large
floating-point values like `3.40282e38px` (commonly generated by
TailwindCSS `.rounded-full` class).
### Root Cause Analysis
**This revealed a broader systemic issue**: The CSS parser was ported
from Rust, which has different float→integer conversion semantics than
Zig's `@intFromFloat`.
**Zig behavior**: `@intFromFloat` panics on out-of-range values
**Rust behavior**: `as` operator follows safe conversion rules:
- Finite values within range: truncate toward zero
- NaN: becomes 0
- Positive infinity: becomes target max value
- Negative infinity: becomes target min value
- Out-of-range finite values: clamp to target range
The crash occurred throughout the CSS codebase wherever `@intFromFloat`
was used, not just in the original failing location.
## 🔧 Comprehensive Solution
### 1. New Generic `bun.intFromFloat` Function
Created a reusable function in `src/bun.zig` that implements
Rust-compatible conversion semantics:
```zig
pub fn intFromFloat(comptime Int: type, value: anytype) Int {
// Handle NaN -> 0
if (std.math.isNan(value)) return 0;
// Handle infinities -> min/max bounds
if (std.math.isPositiveInf(value)) return std.math.maxInt(Int);
if (std.math.isNegativeInf(value)) return std.math.minInt(Int);
// Handle out-of-range values -> clamp to bounds
const min_float = @as(Float, @floatFromInt(std.math.minInt(Int)));
const max_float = @as(Float, @floatFromInt(std.math.maxInt(Int)));
if (value > max_float) return std.math.maxInt(Int);
if (value < min_float) return std.math.minInt(Int);
// Safe conversion for in-range values
return @as(Int, @intFromFloat(value));
}
```
### 2. Systematic Replacement Across CSS Codebase
Replaced **all 18 instances** of `@intFromFloat` in `src/css/` with
`bun.intFromFloat`:
| File | Conversions | Purpose |
|------|-------------|---------|
| `css_parser.zig` | 2 × `i32` | CSS dimension serialization |
| `css_internals.zig` | 9 × `u32` | Browser target version parsing |
| `values/color.zig` | 4 × `u8` | Color component conversion |
| `values/color_js.zig` | 1 × `i64→u8` | Alpha channel processing |
| `values/percentage.zig` | 1 × `i32` | Percentage value handling |
| `properties/custom.zig` | 1 × `i32` | Color helper function |
### 3. Comprehensive Test Coverage
- **New test suite**: `test/internal/int_from_float.test.ts` with inline
snapshots
- **Enhanced regression test**: `test/regression/issue/21907.test.ts`
covering all conversion types
- **Real-world testing**: Validates actual CSS processing with edge
cases
## 📊 esbuild Compatibility Analysis
Compared output with esbuild to ensure compatibility:
**Test CSS:**
```css
.test { border-radius: 3.40282e38px; }
.colors { color: rgb(300, -50, 1000); }
.boundaries { width: 2147483648px; }
```
**Key Differences:**
1. **Scientific notation format:**
- esbuild: `3.40282e38` (no explicit + sign)
- Bun: `3.40282e+38` (explicit + sign)
- ✅ Both are mathematically equivalent and valid CSS
2. **Optimization strategy:**
- esbuild: Preserves original literal values
- Bun: Normalizes extremely large values + consolidates selectors
- ✅ Bun's more aggressive optimization results in smaller output
### ❓ Question for Review
**@zackradisic** - Is it acceptable for Bun to diverge from esbuild in
this optimization behavior?
- **Pro**: More aggressive optimization (smaller output, consistent
formatting)
- **Con**: Different output format than esbuild
- **Impact**: Both outputs are functionally identical in browsers
Should we:
1. ✅ Keep current behavior (more aggressive optimization)
2. 🔄 Match esbuild exactly (preserve literal notation)
3. 🎛️ Add flag to control this behavior
## ✅ Testing & Validation
- [x] **Original crash case**: Fixed - no more panics with large
floating-point values
- [x] **All conversion types**: Tested i32, u32, u8, i64 conversions
with edge cases
- [x] **Browser compatibility**: Verified targets parsing works with
extreme values
- [x] **Color processing**: Confirmed RGB/RGBA values properly clamped
to 0-255 range
- [x] **Performance**: No regression - conversions are equally fast
- [x] **Real-world**: TailwindCSS projects with `.rounded-full` work
without crashes
- [x] **Inline snapshots**: Capture exact expected output for future
regression detection
## 🎯 Impact
### Before (Broken)
```bash
$ bun build styles.css
============================================================
panic: integer part of floating point value out of bounds
```
### After (Working)
```bash
$ bun build styles.css
Bundled 1 module in 93ms
styles.css 121 bytes (asset)
```
- ✅ **Fixes crashes** when using TailwindCSS `.rounded-full` class on
Windows
- ✅ **Maintains backward compatibility** for existing projects
- ✅ **Improves robustness** across all CSS float→int conversions
- ✅ **Better optimization** with consistent value normalization

Hopefully fix https://github.com/oven-sh/bun/issues/21879
### How did you verify your code works?
Added a test with a seed larger than u32.
The test vector is from this tiny test I wrote to rule out upstream zig
as the culprit:
```zig

const testing = std.testing;
test "xxhash64 of short string with custom seed" {
const input = "";
const seed: u64 = 16269921104521594740;
const hash = std.hash.XxHash64.hash(seed, input);
const expected_hash: u64 = 3224619365169652240;

## Summary
Fixes#21704
Replace custom `ShimmedStdin` and `ShimmedStdioOutStream` classes with
proper Node.js `Readable`/`Writable` streams that are immediately
destroyed. This provides better compatibility and standards compliance
while maintaining the same graceful error handling behavior.
## Changes
- ✂️ **Remove shimmed classes**: Delete `ShimmedStdin` and
`ShimmedStdioOutStream` (~40 lines of code)
- 🔄 **Replace with standard streams**:
- `ShimmedStdin` → destroyed `Writable` stream with graceful write
handling
- `ShimmedStdioOutStream` → destroyed `Readable` stream
- 🛡️ **Maintain compatibility**: Streams return `false` for writes and
handle operations gracefully without throwing errors
- ✅ **Standards compliant**: Uses proper Node.js stream inheritance and
behavior
## Technical Details
The new implementation creates streams that are immediately destroyed
using `.destroy()`, which properly marks them as unusable while still
providing the expected stream interface. The `Writable` streams include
a custom `write()` method that always returns `false` and calls
callbacks to prevent hanging, matching the original shimmed behavior.
## Test plan
- [x] Verified basic child_process functionality works
- [x] Tested error cases (non-existent processes, killed processes)
- [x] Confirmed graceful handling of writes to destroyed streams
- [x] Validated stream state properties (`.destroyed`, `.readable`,
etc.)
- [x] Ensured no exceptions are thrown during normal operation

## Summary
Fixes issue #21677 where `Bun.serve()` was adding redundant Date headers
when users provided their own Date header in the response.
The root cause was that the HTTP server was writing user-provided Date
headers and then µWebSockets was automatically adding its own Date
header without checking if one already existed.
## Changes
- **Added Date header detection in `NodeHTTP.cpp`**: When a user
provides a Date header (either in common or uncommon headers), the code
now sets the `HTTP_WROTE_DATE_HEADER` flag to prevent µWebSockets from
automatically adding another Date header
- **Case-insensitive header matching**: Uses
`WTF::equalIgnoringASCIICase` for proper header name comparison in
uncommon headers
- **Comprehensive test coverage**: Added regression tests that verify no
duplicate Date headers in all scenarios (static responses, dynamic
responses, proxy responses)
## Test Plan
- [x] Added comprehensive regression test in
`test/regression/issue/21677.test.ts`
- [x] Tests verify only one Date header exists in all response scenarios
- [x] Tests fail with current main branch (confirms bug exists)
- [x] Tests pass with this fix (confirms bug is resolved)
- [x] Existing Date header tests still pass (no regression)
## Testing
The reproduction case from the issue now works correctly:
**Before (multiple Date headers):**
```
HTTP/1.1 200 OK
Date: Thu, 07 Aug 2025 17:02:24 GMT
content-type: text/plain;charset=utf-8
Date: Thu, 07 Aug 2025 17:02:23 GMT
```
**After (single Date header):**
```
HTTP/1.1 200 OK
Date: Thu, 07 Aug 2025 17:02:23 GMT
content-type: text/plain;charset=utf-8
```

### What does this PR do?
This does two things:
1. Fix an ASAN use-after-poison on macOS involving `ws` module when
running websocket.test.js. This was caused by the `open` callback firing
before the `.upgrade` function call returns. We need to update the
`socket` value on the ServerWebSocket to ensure the `NodeHTTPResponse`
object is kept alive for as long as it should be, but the `us_socket_t`
address can, in theory, change due to `realloc` being used when adopting
the socket.
2. Fixes an "undefined is not a function" error when the websocket
upgrade fails. This occurred because the `_httpMessage` property is not
set when a socket is upgraded
### How did you verify your code works?
There is a test and the asan error no longer triggers

Add an owned pointer type—a wrapper around a pointer and an allocator.
`Owned(*Foo)` and `Owned([]Foo)` contain both the pointer/slice and the
allocator that was used to allocate it. Calling `deinit` on these types
first calls `Foo.deinit` and then frees the memory. This makes it easier
to remember to free the memory, and hard to accidentally free it with
the wrong allocator.
Optional pointers are also supported (`Owned(?*Foo)`, `Owned(?[]Foo)`),
and an unmanaged variant which doesn't store the allocator
(`Owned(*Foo).Unmanaged`) is available for cases where space efficiency
is a concern.
A `MaybeOwned` type is also provided for representing data that could be
owned or borrowed. If the data is owned, `MaybeOwned.deinit` works like
`Owned.deinit`; otherwise, it's a no-op.

## Summary
Optimizes the `--lockfile-only` flag to skip downloading **npm package
tarballs** since they're not needed for lockfile generation. This saves
bandwidth and improves performance for lockfile-only operations while
preserving accuracy for non-npm dependencies.
## Changes
- **Add `prefetch_resolved_tarballs` flag** to
`PackageManagerOptions.Do` struct (defaults to `true`)
- **Set flag to `false`** when `--lockfile-only` is used
- **Skip tarball downloads for npm packages only** when flag is
disabled:
- `getOrPutResolvedPackageWithFindResult` - Main npm package resolution
(uses `Task.Id.forNPMPackage`)
- `enqueuePackageForDownload` - NPM package downloads (uses
`bun.Semver.Version`)
- **Preserve tarball downloads for non-npm dependencies** to maintain
lockfile accuracy:
- Remote tarball URLs (needed for lockfile generation)
- GitHub dependencies (needed for lockfile generation)
- Generic tarball downloads (may be remote)
- Patch-related downloads (needed for patch application)
- **Add comprehensive test** that verifies only package manifests are
fetched for npm packages with `--lockfile-only`
## Rationale
Only npm registry packages can safely skip tarball downloads during
lockfile generation because:
✅ **NPM packages**: Metadata is available from registry manifests,
tarball not needed for lockfile
❌ **Remote URLs**: Need tarball content to determine package metadata
and generate accurate lockfile
❌ **GitHub deps**: Need tarball content to extract package.json and
determine dependencies
❌ **Tarball URIs**: Need content to determine package structure and
dependencies
This selective approach maximizes bandwidth savings while ensuring
lockfile accuracy.
## Test Plan
- ✅ New test in `test/cli/install/lockfile-only.test.ts` verifies only
npm manifest URLs are requested
- ✅ Uses absolute package versions to ensure the npm resolution code
path is hit
- ✅ Test output normalized to work with both debug and non-debug builds
- ✅ All existing install/update tests still pass (including remote
dependency tests)
## Performance Impact
For `--lockfile-only` operations with npm packages, this eliminates
unnecessary tarball downloads, reducing:
- **Network bandwidth usage** (manifests only, not tarballs)
- **Installation time** (no tarball extraction/processing)
- **Cache storage requirements** (tarballs not cached)
The optimization only affects npm packages in `--lockfile-only` mode and
has zero impact on:
- Regular installs (npm packages still download tarballs)
- Remote dependencies (always download tarballs for accuracy)
- GitHub dependencies (always download tarballs for accuracy)
## Files Changed
- `src/install/PackageManager/PackageManagerOptions.zig` - Add flag and
configure for lockfile-only
- `src/install/PackageManager/PackageManagerEnqueue.zig` - Skip npm
tarball generation selectively
- `test/cli/install/lockfile-only.test.ts` - Test with dummy registry

### What does this PR do?
Defers exceptions thrown by NAPI code until execution returns/flows to
JS code.
### How did you verify your code works?
Ran existing NAPI tests and added to napi.test.ts.
We can't use `std.heap.c_allocator` as `z_allocator`; it doesn't
zero-initialize the memory. This PR adds a fallback implementation.
This PR also makes Bun compile successfully with `use_mimalloc` set to
false. More work is likely necessary to make it function correctly in
this case, but it should at least compile.

### What does this PR do?
cases like `@prisma/engines-version` with version of
`6.14.0-17.fba13060ef3cfbe5e95af3aaba61eabf2b8a8a20` was having issues
with the version and using a "corrupted" string instead
