BCR Publication Blocked by git_override Dependency

[avrabe]

Problem

The BCR (Bazel Central Registry) publication workflow is currently blocked because our MODULE.bazel file uses a git_override for rules_rust to support wasm32-wasip2 targets.

Current Configuration

bazel_dep(name = "rules_rust", version = "0.62.0")

# Git override to use rules_rust fork with wasm32-wasip2 support  
git_override(
    module_name = "rules_rust",
    commit = "1945773a",  # Fixed rust_toolchain for WASI SDK tools
    remote = "https://github.com/avrabe/rules_rust.git",
)

BCR Requirement

The Bazel Central Registry requires that all dependencies use official releases and cannot include git overrides or other non-registry dependencies.

Solution Options

1. Wait for Official Support: Wait for official rules_rust to support wasm32-wasip2 targets

   • The Rust compiler added Tier 2 support for wasm32-wasip2 in Rust 1.82 (October 2024)
   • Need to track when rules_rust adds this support officially

2. Conditional Configuration: Create a separate MODULE.bazel variant for BCR publication

   • Keep current configuration for development
   • Use conditional logic or separate files for BCR releases

3. Contribute Upstream: Help contribute the necessary changes to official rules_rust

Current Status

• ✅ BCR workflow files are prepared (.bcr/ directory, publish-to-bcr.yml)
• ✅ Release workflow is ready
• ❌ Cannot publish to BCR until dependency conflict is resolved

Files Ready

• .bcr/metadata.template.json
• .bcr/source.template.json
• .bcr/presubmit.yml
• .github/workflows/publish-to-bcr.yml
• .github/workflows/release.yml

Next Steps

• Monitor rules_rust releases for official wasm32-wasip2 support
• Consider contributing upstream to rules_rust
• Test BCR workflow once dependencies are resolved

🎉 RESOLVED: BCR Publication Now Unblocked!

✅ Issue Resolution

The dependency has been successfully removed! Our WASI Preview 2 support changes were officially merged into rules_rust and are now available in the official release.

📋 Changes Made

• Upgraded to rules_rust 0.65.0 (official release)
• Removed git_override from MODULE.bazel
• Updated documentation to reflect official dependency
• Updated BCR README status from "🚧 Blocked" to "✅ Ready for Publication"

🔑 Your Contribution Success

Your pull request bazelbuild/rules_rust#3507 was merged into rules_rust 0.64.0, adding:

• wasm32-wasip2 to DEFAULT_EXTRA_TARGET_TRIPLES
• Official WASI Preview 2 support
• Enhanced target coverage

🚀 BCR Publication Status

Now Ready: The major blocker is resolved. Remaining prerequisites:

• Remove git_override dependency ✅
• Use only official registry dependencies ✅
• Set up BCR_PUBLISH_TOKEN secret in repository settings
• Create fork of bazel-central-registry in the pulseengine organization

📦 Next Release

This will be included in the next release as a BREAKING CHANGE since users will need to update their MODULE.bazel files to use the new official rules_rust version.

Ready to close this issue and proceed with BCR publication setup! 🎯
