Workflows
Revert-First Stabilization Workflow
In high-impact regressions, restore service stability first and separate root-cause fixes afterward to reduce incident duration and secondary risk.
- Teams turning commands into repeatable routines
- Readers who need sequencing, branch, and sync discipline
- Basic understanding of fetch, pull, push, and branches
- A sense of how and why branches diverge
- Copying a workflow without checking branch state
- Choosing the wrong integration path on shared branches
During production regressions, teams often try to diagnose and patch live at the same time. Revert-first separates goals: restore stability first, then fix root cause safely.
When revert should be the default
- customer-impacting path is degraded and blast radius is growing
- root cause is still uncertain under time pressure
- one or more likely commits can be identified
Minimal execution sequence
1. Identify likely offending changes
git log --oneline --decorate -20
2. Revert in a dedicated hotfix branch
git switch -c hotfix/revert-login-regression
git revert <bad-commit>
For multiple commits, revert in controlled order and include incident ID in commit messages.
3. Validate quickly and release recovery build
Run critical-path checks and ship the stabilization release early.
4. Perform root-cause fix on a separate branch
Do not stack ad-hoc patching while service remains unstable.
In incident mode, rolling back quickly is often the most mature engineering decision. Recovery first, deep repair second.
Common mistakes
Mistake 1: reverting without follow-up root-cause analysis
The same class of failure often returns later.
Mistake 2: editing directly on main and force-pushing
Use traceable branches and normal release controls, even under urgency.
Mistake 3: bundling unrelated changes in emergency patches
Keep emergency change scope minimal to avoid widening validation surface.
- Pick a past regression and reconstruct timeline.
- Write the revert-first action sequence.
- Define minimum release gates in incident mode.
- Clarify rollback decision ownership.
