## Summary
- Remove sccache support entirely, use ccache only
- Missing ccache no longer fails the build (just skips caching)
- Remove S3 distributed cache support
## Changes
- Remove `cmake/tools/SetupSccache.cmake` and S3 distributed cache
support
- Simplify `CMakeLists.txt` to only use ccache
- Update `SetupCcache.cmake` to not fail when ccache is missing
- Replace sccache with ccache in bootstrap scripts (sh, ps1)
- Update `.buildkite/Dockerfile` to install ccache instead of sccache
- Update `flake.nix` and `shell.nix` to use ccache
- Update documentation (CONTRIBUTING.md, contributing.mdx,
building-windows.mdx)
- Remove `scripts/build-cache/` directory (was only for sccache S3
access)
## Test plan
- [x] Build completes successfully with `bun bd`

## Summary
- Fixed documentation that incorrectly claimed you could use `[env]` as
a TOML section to set environment variables directly
- The `env` option in bunfig.toml only controls whether automatic `.env`
file loading is disabled (via `env = false`)
- Updated to show the correct approaches: using preload scripts or
`.env` files with `--env-file`
## Test plan
- Documentation-only change, no code changes

## 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
- Adds `import { feature } from "bun:bundle"` for compile-time feature
flag checking
- `feature("FLAG_NAME")` calls are replaced with `true`/`false` at
bundle time
- Enables dead-code elimination through `--feature=FLAG_NAME` CLI
argument
- Works in `bun build`, `bun run`, and `bun test`
- Available in both CLI and `Bun.build()` JavaScript API
## Usage
```ts
import { feature } from "bun:bundle";
if (feature("SUPER_SECRET")) {
console.log("Secret feature enabled!");
} else {
console.log("Normal mode");
}
```
### CLI
```bash
# Enable feature during build
bun build --feature=SUPER_SECRET index.ts
# Enable at runtime
bun run --feature=SUPER_SECRET index.ts
# Enable in tests
bun test --feature=SUPER_SECRET
```
### JavaScript API
```ts
await Bun.build({
entrypoints: ['./index.ts'],
outdir: './out',
features: ['SUPER_SECRET', 'ANOTHER_FLAG'],
});
```
## Implementation
- Added `bundler_feature_flags` (as `*const bun.StringSet`) to
`RuntimeFeatures` and `BundleOptions`
- Added `bundler_feature_flag_ref` to Parser struct to track the
`feature` import
- Handle `bun:bundle` import at parse time (similar to macros) - capture
ref, return empty statement
- Handle `feature()` calls in `e_call` visitor - replace with boolean
based on flags
- Wire feature flags through CLI arguments and `Bun.build()` API to
bundler options
- Added `features` option to `JSBundler.zig` for JavaScript API support
- Added TypeScript types in `bun.d.ts`
- Added documentation to `docs/bundler/index.mdx`
## Test plan
- [x] Basic feature flag enabled/disabled tests (both CLI and API
backends)
- [x] Multiple feature flags test
- [x] Dead code elimination verification tests
- [x] Error handling for invalid arguments
- [x] Runtime tests with `bun run --feature=FLAG`
- [x] Test runner tests with `bun test --feature=FLAG`
- [x] Aliased import tests (`import { feature as checkFeature }`)
- [x] Ternary operator DCE tests
- [x] Tests use `itBundled` with both `backend: "cli"` and `backend:
"api"`

# What does this PR do?
Nyaa~ This PR fixes a small mistake in the documentation where the code
block for a React component test example was using the wrong filename!
(；ω；)💦
It was previously labeled as `matchers.d.ts`, but it should be something
like `myComponent.test.tsx` to properly reflect a test file for a React
component using `@testing-library/react`. 🧁✨
This makes the example clearer and more accurate for developers using
Bun to test their React components~! 💻🌸💕
# How did you verify your code works?

- Document production build configuration via CLI (`--env=PUBLIC_*`) and
`Bun.build` API (`env: "PUBLIC_*"`)
- Explain prefix filtering to avoid exposing sensitive environment

## Summary
- Extends `fetch()` proxy option to accept an object format: `proxy: {
url: string, headers?: Headers }`
- Allows sending custom headers to the proxy server (useful for proxy
authentication, custom routing headers, etc.)
- Headers are sent in CONNECT requests (for HTTPS targets) and direct
proxy requests (for HTTP targets)
- User-provided `Proxy-Authorization` header overrides auto-generated
credentials from URL
## Usage
```typescript
// Old format (still works)
fetch(url, { proxy: "http://proxy.example.com:8080" });
// New object format with headers
fetch(url, {
proxy: {
url: "http://proxy.example.com:8080",
headers: {
"Proxy-Authorization": "Bearer token",
"X-Custom-Proxy-Header": "value"
}
}
});
```
## Test plan
- [x] Test proxy object with url string works same as string proxy
- [x] Test proxy object with headers sends headers to proxy (HTTP
target)
- [x] Test proxy object with headers sends headers in CONNECT request
(HTTPS target)
- [x] Test proxy object with Headers instance
- [x] Test proxy object with empty headers
- [x] Test proxy object with undefined headers
- [x] Test user-provided Proxy-Authorization overrides URL credentials
- [x] All existing proxy tests pass (25 total)

This updates the documentation for `fs.watch()` to use `relativePath`
instead of `filename` in the recursive example, following the same
convention from PR #23990.
When `recursive: true` is set on `fs.watch()`, the callback receives a
relative path to the changed file rather than just a simple filename.
Using `relativePath` as the parameter name makes this distinction
clearer to users.

## Summary
Remove outdated version mentions (1.0.x and 1.1.x) from documentation
for better consistency. These versions are over a year old - you should
be using a recent version of bun :).
## What changed
**Removed version mentions from:**
- `docs/pm/lifecycle.mdx` - v1.0.16 (trusted dependencies)
- `docs/bundler/executables.mdx` - v1.0.23, v1.1.25, v1.1.30 (various
features)
- `docs/guides/install/jfrog-artifactory.mdx` - v1.0.3+ (env var
comment)
- `docs/guides/install/azure-artifacts.mdx` - v1.0.3+ (env var comment)
- `docs/runtime/workers.mdx` - v1.1.13, v1.1.35 (blob URLs, preload)
- `docs/runtime/networking/dns.mdx` - v1.1.9 (DNS caching)
- `docs/guides/runtime/import-html.mdx` - v1.1.5
- `docs/guides/runtime/define-constant.mdx` - v1.1.5
- `docs/runtime/sqlite.mdx` - v1.1.31
**Kept version mentions in:**
- All 1.2.x versions (still recent, less than a year old)
- Benchmark version numbers (e.g., S3 performance comparison with
v1.1.44)
- `docs/guides/install/yarnlock.mdx` (bun.lock introduction context)
- `docs/project/building-windows.mdx` (build requirements)
- `docs/runtime/http/websockets.mdx` (performance benchmarks)
## Why
The docs lack consistency around version mentions - we don't document
every feature's version, so keeping scattered old version numbers looks
inconsistent. These changes represent a small percentage of features
added recently, and users on ancient versions have bigger problems than
needing to know exactly when a feature landed.

### Default behavior
-- For monorepo projects, Bun uses the **isolated** installation strategy by default.
-- For single-project projects, Bun uses the **hoisted** installation strategy by default.
+The default linker strategy depends on your project's lockfile `configVersion`:
+
+| `configVersion` | Using workspaces? | Default Linker |
+| --------------- | ----------------- | -------------- |
+| `1` | ✅ | `isolated` |
+| `1` | ❌ | `hoisted` |
+| `0` | ✅ | `hoisted` |

+
+**New projects**: Default to `configVersion = 1`. In workspaces, v1 uses the isolated linker by default; otherwise it uses hoisted linking.
+
+**Existing Bun projects (made pre-v1.3.2)**: If your existing lockfile doesn't have a version yet, Bun sets `configVersion = 0` when you run `bun install`, preserving the previous hoisted linker default.
+
+**Migrations from other package managers**:
+
+- From pnpm: `configVersion = 1` (using isolated installs in workspaces)
+- From npm or yarn: `configVersion = 0` (using hoisted installs)
You can override the default behavior by explicitly specifying the `--linker` flag or setting it in your configuration file.

## Summary
Updated all example version placeholders in documentation from 1.3.1 and
1.2.20 to 1.3.2.
## Changes
Updated version examples in:
- Installation examples (Linux/macOS and Windows install commands)
- Package manager output examples (`bun install`, `bun publish`, `bun
pm` commands)
- Test runner output examples
- Spawn/child process output examples
- Fetch User-Agent header examples in debugging docs
- `Bun.version` API example
## Notes
- Historical version references (e.g., "As of Bun v1.x.x..." or "Bun
v1.x.x+ required") were intentionally **preserved** as they document
when features were introduced
- Generic package.json version examples (non-Bun package versions) were
**preserved**
- Only example outputs and code snippets showing current Bun version
were updated
