Bug Fix Workflow

Fix $ARGUMENTS using this systematic process.

Step 1: Investigation (parallel)

• Search for related issues: gh issue list --label bug
• Search error patterns: rg "unwrap\(\)|expect\(" src/ and rg "TODO|FIXME" src/
• Review recent commits for potential causes: git log --oneline -20

Step 2: Reproduction

1. Extract error messages and affected context
2. Create a minimal failing test:

   #[test]
   fn test_reproduce_issue() {
       // Minimal reproduction
   }
   

3. Verify the issue: cargo test test_reproduce_issue -- --nocapture

Step 3: Root Cause Analysis

Common categories in this project:

• Parsing: Malformed JSONL handling
• Date/Time: Timezone or format issues
• Paths: Cross-platform path handling
• Memory: Large file processing
• Display: Terminal width/color issues

Step 4: Fix Implementation

1. Add a failing test first
2. Implement the fix
3. Verify the test passes
4. Check for regressions

Step 5: Verification

cargo test <specific_test>
cargo test
cargo test --all-features

Step 6: Regression Prevention

Add a dedicated regression test to prevent recurrence:

#[cfg(test)]
mod regression_tests {
    #[test]
    fn issue_NNN_description() {
        // Ensure this specific issue doesn't reoccur
    }
}

Checklist

• Issue reproduced locally
• Root cause identified
• Fix implemented with tests
• No regressions introduced
• Performance impact assessed
