From the output of ls-files, we remove all but the leftmost path component and then we eliminate duplicates. We do this in a while loop, which is a performance bottleneck when the number of iterations is large (e.g. for 60000 files in linux.git). $ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git real 0m11.876s user 0m4.685s sys 0m6.808s Replacing the loop with the cut command improves performance significantly: $ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git real 0m1.372s user 0m0.263s sys 0m0.167s The measurements were done with Msys2 bash, which is used by Git for Windows. When filtering the ls-files output we take care not to touch absolute paths. This is redundant, because ls-files will never output absolute paths. Remove the unnecessary operations.

Contributed Software Although these pieces are available as part of the official git source tree, they are in somewhat different status. The intention is to keep interesting tools around git here, maybe even experimental ones, to give users an easier access to them, and to give tools wider exposure, so that they can be improved faster. I am not expecting to touch these myself that much. As far as my day-to-day operation is concerned, these subdirectories are owned by their respective primary authors. I am willing to help if users of these components and the contrib/ subtree "owners" have technical/design issues to resolve, but the initiative to fix and/or enhance things _must_ be on the side of the subtree owners. IOW, I won't be actively looking for bugs and rooms for enhancements in them as the git maintainer -- I may only do so just as one of the users when I want to scratch my own itch. If you have patches to things in contrib/ area, the patch should be first sent to the primary author, and then the primary author should ack and forward it to me (git pull request is nicer). This is the same way as how I have been treating gitk, and to a lesser degree various foreign SCM interfaces, so you know the drill. I expect that things that start their life in the contrib/ area to graduate out of contrib/ once they mature, either by becoming projects on their own, or moving to the toplevel directory. On the other hand, I expect I'll be proposing removal of disused and inactive ones from time to time. If you have new things to add to this area, please first propose it on the git mailing list, and after a list discussion proves there are some general interests (it does not have to be a list-wide consensus for a tool targeted to a relatively narrow audience -- for example I do not work with projects whose upstream is svn, so I have no use for git-svn myself, but it is of general interest for people who need to interoperate with SVN repositories in a way git-svn works better than git-svnimport), submit a patch to create a subdirectory of contrib/ and put your stuff there. -jc
