# [PATCH] Fix contrib/hooks/post-receive-email for new duplicate branch 1 messages from 2009-02-10 to 2009-02-10. Participants: Pat Notz. Thread: https://gitlist.dev/t/17704 ## Pat Notz, 2009-02-10 16:18 Subject: [PATCH] Fix contrib/hooks/post-receive-email for new duplicate branch Message-ID: <1234282707-6295-1-git-send-email-pknotz@sandia.gov> URL: https://gitlist.dev/e/1234282707-6295-1-git-send-email-pknotz%40sandia.gov ``` In the show_new_revisions function, the original code: git rev-parse --not --branches | grep -v $(git rev-parse $refname) | isn't quite right since one can create a new branch and push it without any new commits. In that case, two refs will have the same sha1 but both would get filtered by the 'grep'. In the end, we'll show ALL the history which is not what we want. Instead, we should list the branches by name and remove the branch being updated and THEN pass that list through rev-parse. Revised as suggested by Jakub Narebski to use git-for-each-ref instead of git-branch. (Thanks!)
