Deployment

This repository maintains (semi-)automated weekly updates from nixpkgs-unstable. The system automatically:

• Fetches the latest nixpkgs-unstable commits
• Applies any patches from the patches directory
• Runs the comprehensive devenv test suite across multiple platforms
• Updates the bump-rolling branch weekly every Monday at 9:00 UTC

Manual Updates

To manually trigger an update outside the weekly schedule:

1. Add patches (if needed): Place .patch files in the patches directory

2. Run the sync workflow:

   gh workflow run "Sync and test rolling"

   You can also specify custom parameters:

   gh workflow run "Sync and test rolling" \
     -f target-branch=bump-rolling \
     -f upstream-ref=nixpkgs-unstable

Release Process

To promote changes from bump-rolling to the stable rolling branch:

1. Fetch latest changes:

   git fetch origin

2. Reset rolling to bump-rolling and deploy:

   git checkout rolling
   git reset --hard origin/bump-rolling
   git push origin rolling --force-with-lease

3. Create a timestamped backup of the released rolling branch:

   This will safe-guard the release from garbage-collection when rolling is bumped again.

   git checkout -b rolling-$(date +%Y-%m-%d)
   git push origin rolling-$(date +%Y-%m-%d)

This ensures that the stable rolling branch contains thoroughly tested changes while maintaining historical snapshots of previous releases.
