t1049: Stash dirty worktree before rebase (follow-up)#1481
Conversation
…d changes' error Failed AI conflict resolution leaves staged changes in the worktree. Subsequent rebase attempts fail with 'cannot rebase: uncommitted changes'. Uses git stash (not reset) so changes are recoverable via git stash list in case a human had uncommitted work in the worktree.
Summary of ChangesHello @marcusquinn, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the robustness of the rebase process within the deployment script. It introduces a pre-rebase check that intelligently handles uncommitted changes by stashing them, thereby preventing common rebase errors and improving the recoverability of developer work, particularly in scenarios involving automated conflict resolution.

Code Review
This pull request enhances the rebase logic by stashing a dirty worktree to prevent errors, which is a good improvement. My review includes two suggestions: one to correct a misleading comment to accurately reflect the new stashing mechanism, and another to align an error redirection with the repository's style guide for better logging and debuggability. None of the provided rules contradict these comments.

This comment is misleading as it mentions 'Reset index and restore working tree', but the implementation now uses git stash. The PR description correctly explains the choice of stash over reset. To avoid confusion and maintain consistency, please update the comment to reflect that the worktree is cleaned by stashing changes.
| # 2. Reset index and restore working tree (prevents "uncommitted changes" errors | |
| # left by the AI conflict resolver's git-add on a subsequently aborted rebase) | |
| # 2. Stash dirty index/worktree (prevents "uncommitted changes" errors | |
| # left by the AI conflict resolver's git-add on a subsequently aborted rebase) |
| # Stash dirty index/worktree — failed AI resolution can leave staged | ||
| # changes even after rebase --abort clears the rebase state. | ||
| # Uses stash (not reset) so changes are recoverable via `git stash list`. | ||

According to the repository style guide (line 50), 2>/dev/null should generally be avoided in favor of redirecting errors to a log file. To improve debuggability and adhere to the style guide, please redirect stderr to $SUPERVISOR_LOG. This will help diagnose issues if git status fails unexpectedly.
| if [[ -n "$(git -C "$git_dir" status --porcelain 2>/dev/null)" ]]; then | |
| if [[ -n "$(git -C \"$git_dir\" status --porcelain 2>>\"$SUPERVISOR_LOG\")" ]]; then |
