Start with a problem
Your team is collaborating on a project, branches are growing, merges are becoming more frequent — but there's no stable collaboration rhythm. Everyone syncs code their own way, and conflicts are piling up.
Why this deserves its own workflow
Long-lived branch syncs mainFrequent rebase produces same conflictsMultiple developers modify same area
Regular sync → fewer conflictsIdentify hotspots → prioritize architecture fixesrerere → auto-reuse resolutions
rerere (reuse recorded resolution) records conflict solutions and auto-applies them next time the same conflict occurs.
Long-lived branches do not just "have conflicts." They tend to produce recurring, predictable, high-cost conflict zones.
The real upgrade is moving from repeated firefighting to deliberate governance.
A steadier approach
- set a sync cadence
- identify conflict hotspots
- reuse repeated conflict resolutions where appropriate
- feed that knowledge back into branch and module boundaries
Common mistakes
- treating every conflict as a one-off event
- relying on one maintainer to carry all merge pain
- enabling reuse mechanisms but never validating the outcome
Try it yourself
- Practice the long-lived-branch-conflict-governance command in a test repository and observe state changes before and after
- Experiment with different options and compare the output differences
- Simulate a real scenario where you would need to use this, and walk through the full process
