Hi, I wanted to report something interesting that I found while tracing a severe slowdown in git-prompt.sh.
https://github.com/git/git/commit/6d158cba282f22fa1548af1188f78042fed30aed#diff-f37c4f4a898819f0ca4b5ff69e81d4d9R141 Way back in this commit, someone added a useful chunk of code that works perfectly with svn+ssh:// URLs under basic regexes: + local svn_upstream=($(git log --first-parent -1 \ + --grep="^git-svn-id: \(${svn_url_pattern:2}\)" 2>/dev/null)) However, if I switch over to Perl regexes (or Extended): git config --global grep.patternType perl Then the command runs for one wall clock second and shows incorrect results on my repository. I eventually traced this to an issue with the regular expression provided, assuming the svn repository url is "svn+ssh://...": git log ... --grep="^git-svn-id: \(svn+ssh://...\)" 2>/dev/null The + sign isn't escaped in git-prompt.sh, which under non-basic regexes causes the match to fail entirely. - R. ps. git log --basic-regexp does not fix the issue, as for unknown reasons (I'll start another thread) the command-line option doesn't override grep.patternType. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
