It turned out to not be a bug we need to fix. However, out of that discussion came the idea of libifying reflog. This can stand alone as a code improvement. stash.c currently shells out to call reflog to delete reflogs. Libify reflog delete and call it from both builtin/reflog.c and builtin/stash.c. This patch has three parts: * add missing test coverage for git stash delete * libify reflog's delete functionality and move some of the helpers into a reflog.c library and call reflog_delete from builtin/reflog.c * call reflog_delete from builtin/stash.c Updates since v3: * refactored test to have a smaller diff Updates since v2: * removed unnecessary includes * adjusted wrapping/whitespace in reflog.h * adjusted test to be isolated from other tests since currently tests for stash depend on each other. There was some discussion around this and even a possibility to refactor the tests. However, it would have been a larger effort than is worth for this series, so instead I just made one of the tests I added be isolated from the others. Updates since v1: * added missing test coverage * squashed 1/3 and 2/3 together * moved enum into reflog.c * updated object.h's flag allocation mapping 1. https://lore.kernel.org/git/220126.86h79qe692.gmgdl@evledraar.gmail.com/ John Cai (3): stash: add tests to ensure reflog --rewrite --updatref behavior reflog: libify delete reflog function and helpers stash: call reflog_delete() in reflog.c Makefile | 1 + builtin/reflog.c | 455 +---------------------------------------------- builtin/stash.c | 18 +- object.h | 2 +- reflog.c | 432 ++++++++++++++++++++++++++++++++++++++++++++ reflog.h | 43 +++++ t/t3903-stash.sh | 43 ++++- 7 files changed, 527 insertions(+), 467 deletions(-) create mode 100644 reflog.c create mode 100644 reflog.h base-commit: e6ebfd0e8cbbd10878070c8a356b5ad1b3ca464e Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-git-1218%2Fjohn-cai%2Fjc-libify-reflog-v4 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-git-1218/john-cai/jc-libify-reflog-v4 Pull-Request: https://github.com/git/git/pull/1218 Range-diff vs v3: 1: 33299825fc4 ! 1: 08bb8d3a9b9 stash: add tests to ensure reflog --rewrite --updatref behavior @@ t/t3903-stash.sh: diff_cmp () { } -test_expect_success 'stash some dirty working directory' ' -- echo 1 >file && -- git add file && -- echo unrelated >other-file && -- git add other-file && +setup_stash() { -+ repo_dir=$1 -+ if test -z $repo_dir; then -+ repo_dir="." -+ fi -+ -+ echo 1 >$repo_dir/file && -+ git -C $repo_dir add file && -+ echo unrelated >$repo_dir/other-file && -+ git -C $repo_dir add other-file && - test_tick && -- git commit -m initial && -- echo 2 >file && -+ git -C $repo_dir commit -m initial && -+ echo 2 >$repo_dir/file && + echo 1 >file && git add file && -- echo 3 >file && -+ echo 3 >$repo_dir/file && - test_tick && -- git stash && -- git diff-files --quiet && -- git diff-index --cached --quiet HEAD -+ git -C $repo_dir stash && -+ git -C $repo_dir diff-files --quiet && -+ git -C $repo_dir diff-index --cached --quiet HEAD + echo unrelated >other-file && +@@ t/t3903-stash.sh: test_expect_success 'stash some dirty working directory' ' + git stash && + git diff-files --quiet && + git diff-index --cached --quiet HEAD +} + +test_expect_success 'stash some dirty working directory' ' @@ t/t3903-stash.sh: test_expect_success 'drop middle stash by index' ' + +test_expect_success REFFILES 'drop stash reflog updates refs/stash with rewrite' ' + git init repo && -+ setup_stash repo && ++ ( ++ cd repo && ++ setup_stash ++ ) && + echo 9 >repo/file && + + old_oid="$(git -C repo rev-parse stash@{0})" && 2: 33adfee4ca6 = 2: 50471c2ee6f reflog: libify delete reflog function and helpers 3: b17d8e5d43a = 3: cb32d9bfe60 stash: call reflog_delete() in reflog.c -- gitgitgadget
