* `IncrementalGraph(.client).File` packs its fields in a specific way to
save space, but it makes the struct hard to use and error-prone (e.g.,
untagged unions with tags stored in a separate `flags` struct). This PR
changes `File` to have a human-readable layout, but adds methods to
convert it to and from `File.Packed`, a packed version with the same
space efficiency as before.
* Reduce the need to pass the dev allocator to functions (e.g.,
`deinit`) by storing it as a struct field via the new `DevAllocator`
type. This type has no overhead in release builds, or when
`AllocationScope` is disabled.
* Use owned pointers in `PackedMap`.
* Use `bun.ptr.Shared` for `PackedMap` instead of the old
`bun.ptr.RefPtr`.
* Add `bun.ptr.ScopedOwned`, which is like `bun.ptr.Owned`, but can
store an `AllocationScope`. No overhead in release builds or when
`AllocationScope` is disabled.
* Reduce redundant allocators in `BundleV2`.
* Add owned pointer conversions to `MutableString`.
* Make `AllocationScope` behave like a pointer, so it can be moved
without invalidating allocations. This eliminates the need for
self-references.
* Change memory cost algorithm so it doesn't rely on “dedupe bits”.
These bits used to take advantage of padding but there is now no padding
in `PackedMap`.
* Replace `VoidFieldTypes` with `useAllFields`; this eliminates the need
for `voidFieldTypesDiscardHelper`.

Add a new reference-counted shared pointer type, `bun.ptr.Shared`.
Features:
* Can hold data of any type; doesn't require adding a `ref_count` field
* Reference count is an internal implementation detail; will never get
out of sync due to erroneous manipulation
* Supports weak pointers
* Supports optional pointers with no overhead (`Shared(?*T)` is the same
size as `Shared(*T)`)
* Has an atomic thread-safe version: `bun.ptr.AtomicShared`
* Defaults to `bun.default_allocator`, but can handle other allocators
as well, with both static and dynamic polymorphism
The following types are now deprecated and will eventually be removed:
* `bun.ptr.RefCount`
* `bun.ptr.ThreadSafeRefCount`
* `bun.ptr.RefPtr`
* `bun.ptr.WeakPtr`

### What does this PR do?
Introduce `Bun.stripANSI`, a SIMD-accelerated drop-in replacement for
the popular `"strip-ansi"` package.
`Bun.stripANSI` performs >10x faster and fixes several bugs in
`strip-ansi`, like [this long-standing
one](https://github.com/chalk/strip-ansi/issues/43).
### How did you verify your code works?
There are tests that check the output of `strip-ansi` matches
`Bun.stripANSI`. For cases where `strip-ansi`'s behavior is incorrect,
the expected value is manually provided.

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.
(For internal tracking: fixes STAB-920, STAB-921)
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.
(For internal tracking: fixes STAB-978, STAB-979)
* Move `DebugThreadLock` to `bun.safety`
* Enable in `ci_assert` builds, but store stack traces only in debug
builds
* Reduce size of struct by making optional field non-optional
* Add `initLockedIfNonComptime` as a workaround for not being able to
call `initLocked` in comptime contexts
* Add `lockOrAssert` method to acquire the lock if unlocked, or else
assert that the current thread acquired the lock
* Add stack traces to `CriticalSection` and `AllocPtr` in debug builds
* Make `MimallocArena.init` infallible
* Make `MimallocArena.heap` non-nullable
* Rename `RefCount.active_counts` to `raw_count` and provide read-only
`get` method
* Add `bun.safety.alloc.assertEq` to assert that two allocators are
equal (avoiding comparison of undefined `ptr`s)

### What does this PR do?
The `then` function in `transpiler.transform` can cause GC, which means
it can cause the `Transpiler` to become freed, which means that if that
same transpiler is in use by another run on the other thread, it could
have pointers to invalid memory.
Also, `ESMCondition` has unnecesasry memory allocations and there is a
very tiny memory leak in optionsFromLoaders

### What does this PR do?
Instead of holding a strong for the options object passed with the
handlers, we make each of the callbacks kept alive by the handlers and
it detaches once the detachFromJS function is called.
This should fix#21570, which looks like it was caused by wrapper
functions for AsyncLocalStorage getting collected prematurely.

Add a helper type to help detect race conditions. There's no performance
or memory use penalty in release builds.
Actually adding the type to various places will be left for future PRs.

### What does this PR do?
fixes#6409
This PR implements `bun install` automatic migration from yarn.lock
files to bun.lock, preserving versions exactly. The migration happens
automatically when:
1. A project has a `yarn.lock` file
2. No `bun.lock` or `bun.lockb` file exists
3. User runs `bun install`
### Current Status: ✅ Complete and Working
The yarn.lock migration feature is **fully functional and
comprehensively tested**. All dependency types are supported:
- ✅ Regular npm dependencies (`package@^1.0.0`)
- ✅ Git dependencies (`git+https://github.com/user/repo.git`,
`github:user/repo`)
- ✅ NPM alias dependencies (`alias@npm:package@version`)
- ✅ File dependencies (`file:./path`)
- ✅ Remote tarball URLs (`https://registry.npmjs.org/package.tgz`)
- ✅ Local tarball files (`file:package.tgz`)
### Test Results
```bash
$ bun bd test test/cli/install/migration/yarn-lock-migration.test.ts
✅ 4 pass, 0 fail
- yarn-lock-mkdirp (basic npm dependency)
- yarn-lock-mkdirp-no-resolved (npm dependency without resolved field)
- yarn-lock-mkdirp-file-dep (file dependency)
- yarn-stuff (all complex dependency types: git, npm aliases, file, remote tarballs)
```
### How did you verify your code works?
1. **Comprehensive test suite**: Added 4 test cases covering all
dependency types
2. **Version preservation**: Verified that package versions are
preserved exactly during migration
3. **Real-world scenarios**: Tested with complex yarn.lock files
containing git deps, npm aliases, file deps, and remote tarballs
4. **Migration logging**: Confirms migration with log message `[X.XXms]
migrated lockfile from yarn.lock`
### Key Implementation Details
- **Core parser**: `src/install/yarn.zig` handles all yarn.lock parsing
and dependency type resolution
- **Integration**: Migration is built into existing lockfile loading
infrastructure
- **Performance**: Migration typically completes in ~1ms for most
projects
- **Compatibility**: Preserves exact dependency versions and resolution
behavior
The implementation correctly handles edge cases like npm aliases, git
dependencies with commits, file dependencies with transitive deps, and
remote tarballs.

### What does this PR do?
<!-- **Please explain what your changes do** -->
This PR should fix#14219 and implement
`WebAssembly.instantiateStreaming()` and
`WebAssembly.compileStreaming()`.
This is a mixture of WebKit's implementation (using a helper,
`handleResponseOnStreamingAction`, also containing a fast-path for
blobs) and some of Node.js's validation (error messages) and its
builtin-based strategy to consume chunks from streams.
`src/bun.js/bindings/GlobalObject.zig` has a helper function
(`getBodyStreamOrBytesForWasmStreaming`), called by C++, to validate the
response (like
[Node.js](214e4db60e/lib/internal/wasm_web_api.js)
does) and to extract the data from the response, either as a slice/span
(if we can get the data synchronously), or as a `ReadableStream` body
(if the data is still pending or if it is a file/S3 `Blob`).
In C++, `handleResponseOnStreamingAction` is called by
`compileStreaming` and `instantiateStreaming` on the
`JSC::GlobalObjectMethodTable`, just like in
[WebKit](97ee3c598a/Source/WebCore/bindings/js/JSDOMGlobalObject.cpp (L517)).
It calls the aforementioned Zig helper for validation and getting the
response data. The data is then fed into `JSC::Wasm::StreamingCompiler`.
If the data is received as a `ReadableStream`, then we call a JS builtin
in `WasmStreaming.ts` to iterate over each chunk of the stream, like
[Node.js](214e4db60e/lib/internal/wasm_web_api.js (L50-L52))
does. The `JSC::Wasm::StreamingCompiler` is passed into JS through a new
wrapper object, `WebCore::WasmStreamingCompiler`, like
[Node.js](214e4db60e/src/node_wasm_web_api.h)
does. It has `addBytes`, `finalize`, `error`, and (unused) `cancel`
methods to mirror the underlying JSC class.
(If there's a simpler way to do this, please let me know...that would be
very much appreciated)

Ensure we aren't using multiple allocators with the same list by storing
a pointer to the allocator in debug mode only.
This check is stricter than the bare minimum necessary to prevent
illegal behavior, so CI may reveal certain uses that fail the checks but
don't cause IB. Most of these cases should probably be updated to comply
with the new requirements—we want these types' invariants to be clear.
