Key Workflows
1. Initial Setup
# Verify prerequisites
./scripts/verify-prerequisites.sh
# Setup TYPO3 Core development environment
./scripts/setup-typo3-coredev.sh
2. Create Patch
# Create feature branch
git checkout -b feature/issue-number-description
# Make changes, commit with proper format
git commit -m "[BUGFIX] Fix indexed search null handling
Resolves: #105737
Releases: main"
3. Submit to Gerrit
# Submit as WIP (Work in Progress)
git push origin HEAD:refs/for/main%wip
# After CI passes, mark as ready
git commit --amend --allow-empty --no-edit
git push origin HEAD:refs/for/main%ready
4. Handle CI Failures
The skill provides systematic debugging:
- Check ALL failed job logs
- Identify failure patterns (cgl, phpstan, unit tests)
- Fix all issues in ONE patchset
- Re-submit and verify
WIP State Management
Command-Line Approach (Recommended)
# Set WIP state
git push origin HEAD:refs/for/main%wip
