# [PATCHv2] mingw_rmdir: do not prompt for retry when non-empty 5 messages from 2012-12-10 to 2012-12-10. Participants: Erik Faye-Lund, Junio C Hamano, Johannes Schindelin. Thread: https://gitlist.dev/t/32306 ## Erik Faye-Lund, 2012-12-10 14:42 Subject: [PATCHv2] mingw_rmdir: do not prompt for retry when non-empty Message-ID: <1355150547-8212-1-git-send-email-kusmabite@gmail.com> URL: https://gitlist.dev/e/1355150547-8212-1-git-send-email-kusmabite%40gmail.com ``` in ab1a11be ("mingw_rmdir: set errno=ENOTEMPTY when appropriate"), a check was added to prevent us from retrying to delete a directory that is both in use and non-empty. However, this logic was slightly flawed; since we didn't return immediately, we end up falling out of the retry-loop, but right into the prompting-loop. Fix this by setting errno, and guarding the prompting-loop with an errno-check.

Is this meant for me, or is it to be applied to msysgit and later somehow fed to me in different form?

I intended for you to apply it, but I didn't realize that my patch was based on the msysGit-master, where Karsten's UTF-8 patches has been applied. I'm not entirely sure what the best approach would be. The issue is present in both branches, but we only build installers from the msysGit-branch. But I think there are other people who builds Git from the upstream source code, so it would be slightly less annoying for them if the patch was fixed up and applied. But on the other hand, that causes some annoyance when (if?) Karsten's UTF-8 patches gets upstreamed.

I will fix the merge conflicts when rebasing onto Junio's master branch next time.
