2020-02-19merge-recursive: fix the refresh logic in update_file_flagsLibravatar Elijah Newren1-1/+1
If we need to delete a higher stage entry in the index to place the file at stage 0, then we'll lose that file's stat information. In such situations we may still be able to detect that the file on disk is the version we want (as noted by our comment in the code: /* do not overwrite file if already present */ ), but we do still need to update the mtime since we are creating a new cache_entry for that file. Update the logic used to determine whether we refresh a file's mtime. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-02-19t3433: new rebase testcase documenting a stat-dirty-like failureLibravatar Elijah Newren1-0/+48
A user discovered a case where they had a stack of 20 simple commits to rebase, and the rebase would succeed in picking the first commit and then error out with a pair of "Could not execute the todo command" and "Your local changes to the following files would be overwritten by merge" messages. Their steps actually made use of the -i flag, but I switched it over to -m to make it simpler to trigger the bug. With that flag, it bisects back to commit 68aa495b590d (rebase: implement --merge via the interactive machinery, 2018-12-11), but that's misleading. If you change the -m flag to --keep-empty, then the problem persists and will bisect back to 356ee4659bb5 (sequencer: try to commit without forking 'git commit', 2017-11-24) After playing with the testcase for a bit, I discovered that added --exec "sleep 1" to the command line makes the rebase succeed, making me suspect there is some kind of discard and reloading of caches that lead us to believe that something is stat dirty, but I didn't succeed in digging any further than that.
