## Summary
This PR introduces a CMake-generated header file containing all
dependency versions, eliminating the need for C++ code to depend on
Zig-exported version constants.
## Changes
- **New CMake script**: `cmake/tools/GenerateDependencyVersions.cmake`
that:
- Reads versions from the existing `generated_versions_list.zig` file
- Extracts semantic versions from header files where available
(libdeflate, zlib)
- Generates `bun_dependency_versions.h` with all dependency versions as
compile-time constants
- **Updated BunProcess.cpp**:
- Now includes the CMake-generated `bun_dependency_versions.h`
- Uses `BUN_VERSION_*` constants instead of `Bun__versions_*`
- Removes dependency on Zig-exported version constants
- **Build system updates**:
- Added `GenerateDependencyVersions` to main CMakeLists.txt
- Added build directory to include paths in BuildBun.cmake
## Benefits
✅ Single source of truth for dependency versions
✅ Versions accessible from C++ without Zig exports
✅ Automatic regeneration during CMake configuration
✅ Semantic versions shown where available (e.g., zlib 1.2.8 instead of
commit hash)
✅ Debug output file for verification
## Test Results
Verified that `process.versions` correctly shows all dependency
versions:
```javascript
$ bun -e "console.log(JSON.stringify(process.versions, null, 2))"
{
"node": "24.3.0",
"bun": "1.2.22-debug",
"boringssl": "29a2cd359458c9384694b75456026e4b57e3e567",
"libarchive": "898dc8319355b7e985f68a9819f182aaed61b53a",
"mimalloc": "4c283af60cdae205df5a872530c77e2a6a307d43",
"webkit": "0ddf6f47af0a9782a354f61e06d7f83d097d9f84",
"zlib": "1.2.8",
"libdeflate": "1.24",
// ... all versions present and correct
}
```
## Generated Files
- `build/debug/bun_dependency_versions.h` - Header file with version
constants
- `build/debug/bun_dependency_versions_debug.txt` - Human-readable
version list

Fixes#21189
`.pause()` should unref but it should still continue to emit `readable`
events (although it should not send `data` events)
also stdin.unref() should not pause input, it should only prevent stdin
from keeping the process alive.
DRAFT:
- [x] ~~this causes a bug where `process.stdin.on("readable", () => {});
process.stdin.pause()` will allow the process to exit when it
shouldn't.~~ fixed
