rebase -i: fix rewording with --committer-date-is-author-date

2021-11-03T17:44:45Z

baf8ec8d3a (rebase -r: don't write .git/MERGE_MSG when fast-forwarding, 2021-08-20) stopped reading the author script in run_git_commit() when rewording a commit. This is normally safe because "git commit --amend" preserves the authorship. However if the user passes "--committer-date-is-author-date" then we need to read the author date from the author script when rewording. Fix this regression by tightening the check for when it is safe to skip reading the author script. Reported-by: Jonas Kittner Signed-off-by: Phillip Wood Signed-off-by: Junio C Hamano

sequencer: fix a memory leak in do_reset()

2021-10-13T17:37:11Z

Fix a memory leak introduced in 9055e401dd6 (sequencer: introduce new commands to reset the revision, 2018-04-25), which called setup_unpack_trees_porcelain() without a corresponding call to clear_unpack_trees_porcelain(). This introduces a change in behavior in that we now start calling clear_unpack_trees_porcelain() even without having called the setup_unpack_trees_porcelain(). That's OK, that clear function, like most others, will accept a zero'd out struct. This inches us closer to passing various tests in "t34*.sh" (e.g. "t3434-rebase-i18n.sh"), but because they have so many other memory leaks in revisions.c this doesn't make any test file or even a single test pass.

sequencer: add a "goto cleanup" to do_reset()

2021-10-13T17:37:11Z

Restructure code that's mostly added in 9055e401dd6 (sequencer: introduce new commands to reset the revision, 2018-04-25) to avoid code duplication, and to make freeing other resources easier in a subsequent commit. It's safe to initialize "tree_desc" to be zero'd out in order to unconditionally free desc.buffer, it won't be initialized on the first couple of "goto"'s. There are three earlier "return"'s in this function which should probably be made to use this new "cleanup" too, per [1] it looks like they're leaving behind stale locks. But let's not try to fix every potential bug here now, I'm just trying to narrowly plug a memory leak. 1. https://lore.kernel.org/git/CABPp-BH=3DP-dXRCphY53-3eZd1TU8h5GY_M12nnbEGm-UYB9Q@mail.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

Remove ignored files by default when they are in the way

2021-09-27T20:38:37Z

Change several commands to remove ignored files by default when they are in the way. Since some commands (checkout, merge) take a --no-overwrite-ignore option to allow the user to configure this, and it may make sense to add that option to more commands (and in the case of merge, actually plumb that configuration option through to more of the backends than just the fast-forwarding special case), add little comments about where such flags would be used. Incidentally, this fixes a test failure in t7112. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano
