This series of 6 patches improves performance for both describe and `show-ref -d` on repositories with a lot of tags, and finally ends with the display of the current tag for detached HEAD in the bash prompt rather than the abbreviated SHA-1. The `show-ref -d` improvements should help both gitk and gitweb performance as it reduces the total number of lstats necessary (we were doing an extra unnecessary lstat on each packed ref). The `describe --exact-match` flag is useful in scripts, as shown by the final patch in the series. 1) Protect peel_ref fallback case from NULL parse_object result 2) Optimize peel_ref for the current ref of a for_each_ref callback 3) Teach git-describe to use peeled ref information when scanning tags 4) Avoid accessing non-tag refs in git-describe unless --all is requested 5) Teach git-describe --exact-match to avoid expensive tag searches 6) Use git-describe --exact-match in bash prompt on detached HEAD Documentation/git-describe.txt | 5 ++++ builtin-describe.c | 35 ++++++++++++++++++++++++------- contrib/completion/git-completion.bash | 5 +++- refs.c | 27 +++++++++++++++++++----- 4 files changed, 57 insertions(+), 15 deletions(-) -- Shawn. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
