[PATCH 2/2] rebase -i: fix post-rewrite hook with failed exec command
Usually, when 'git rebase' stops before completing the rebase, it is to give the user an opportunity to edit a commit (e.g. with the 'edit' command). In such cases, 'git rebase' leaves the sha1 of the commit being rewritten in $state_dir/stopped-sha, and subsequent 'git rebase --continue' will call the post-rewrite hook with this sha1 as old-sha1 argument to the post-rewrite hook. The case of 'git rebase' stopping because of a failed 'exec' command is different: it gives the opportunity to the user to examine or fix the failure, but does not stop saying here's a commit to edit, use --continue when you're done. So, there's no reason to call the post-rewrite hook for 'exec' commands. If the user did rewrite the commit, it would be with 'git commit --amend' which already called the post-rewrite hook. Fix the behavior to leave no stopped-sha file in case of failed exec command, and teach 'git rebase --continue' to skip record_in_rewritten if no stopped-sha file is found. --- git-rebase--interactive.sh | 10 +- t/t5407-post-rewrite-hook.sh | 2 +- 2 files changed, 6 insertions(+), 6 deletions(-) diff --git a/git-rebase--interactive.sh b/git-rebase--interactive.sh index 08e5d86..1c321e4 100644 --- a/git-rebase--interactive.sh +++ b/git-rebase--interactive.sh @@ -486,7 +486,7 @@ do_pick () { } do_next () { - rm -f $msg $author_script $amend || exit + rm -f $msg $author_script $amend $state_dir/stopped-sha || exit read -r command sha1 rest $todo case $command in $comment_char*|''|noop) @@ -576,9 +576,6 @@ do_next () { read -r command rest $todo mark_action_done printf 'Executing: %s\n' $rest - # exec command doesn't take a sha1 in the todo-list. - # = can't just use $sha1 here. - git rev-parse --verify HEAD $state_dir/stopped-sha ${SHELL:-@SHELL_PATH@} -c $rest # Actual execution status=$? # Run in subshell because require_clean_work_tree can die. @@ -874,7 +871,10 @@ first and then run 'git rebase --continue' again. fi fi - record_in_rewritten $(cat $state_dir/stopped-sha) + if test -r $state_dir/stopped-sha + then + record_in_rewritten $(cat $state_dir/stopped-sha) + fi require_clean_work_tree rebase do_rest diff --git a/t/t5407-post-rewrite-hook.sh b/t/t5407-post-rewrite-hook.sh index 53a4062..06ffad6 100755 --- a/t/t5407-post-rewrite-hook.sh +++ b/t/t5407-post-rewrite-hook.sh @@ -212,7 +212,7 @@ EOF verify_hook_input ' -test_expect_failure 'git rebase -i (exec)' ' +test_expect_success 'git rebase -i (exec)' ' git reset --hard D clear_hook_input FAKE_LINES=edit 1 exec_false 2 git rebase -i B --- https://github.com/git/git/pull/138
