Error Handling

Retry Logic

retry_config:
  max_attempts: 2
  backoff_ms: [1000, 2000]
  retryable:
    - timeout
  non_retryable:
    - conflict
    - invalid_reference

Safety Checks

pre_operation_checks:
  - verify_clean_working_tree
  - verify_not_on_shared_branch
  - create_backup_ref

Recovery Operations

Reflog: Your Safety Net

git reflog
# abc1234 HEAD@{0}: commit: Add feature
# def5678 HEAD@{1}: rebase: finished

# Recover "lost" commit
git branch recovery-branch abc1234

Interactive Rebase

git rebase -i HEAD~5

# Commands:
# pick   - keep commit
# reword - edit message
# squash - merge with previous
# drop   - remove commit

Cherry-Pick

git cherry-pick abc1234           # Single commit
git cherry-pick abc1234^..def5678 # Range
git cherry-pick --abort           # On conflict

Git Bisect

git bisect start
git bisect bad
git bisect good abc1234
# Test and mark good/bad until found
git bisect reset

Stash Operations

git stash push -m "WIP feature"
git stash list
git stash apply stash@{0}
git stash pop

Troubleshooting Guide

Debug Checklist

□ 1. Current HEAD? → git rev-parse HEAD
□ 2. Reflog available? → git reflog
□ 3. Operation in progress? → ls .git/

Common Issues

Command Risk Matrix

git reflog

git stash

git cherry-pick

git rebase -i

git filter-repo

Observability

logging:
  level: DEBUG
  events:
    - operation_started
    - backup_created
    - conflict_detected

metrics:
  - rebase_success_rate
  - recovery_operations
