Git with broken hash generation to generate collisions between object IDs. Don't use this!

The functionality we use from compgen is not much, we can do the same manually, with drastic improvements in speed, especially when dealing with only a few words. This patch also has the sideffect that brekage reported by Jeroen Meijer and SZEDER Gábor gets fixed because we no longer expand the resulting words. Here are some numbers filtering N amount of words: == 1 == original: 0.002s new: 0.000s == 10 == original: 0.002s new: 0.000s == 100 == original: 0.003s new: 0.002s == 1000 == original: 0.012s new: 0.011s == 10000 == original: 0.056s new: 0.066s == 100000 == original: 2.669s new: 0.622s If the results are not narrowed: == 1 == original: 0.002s new: 0.000s == 10 == original: 0.002s new: 0.001s == 100 == original: 0.004s new: 0.004s == 1000 == original: 0.020s new: 0.015s == 10000 == original: 0.101s new: 0.355s == 100000 == original: 2.850s new: 31.941s So, unless 'git checkout <tab>' usually gives you more than 10000 results, you'll get an improvement :) Other possible solutions perform better after 1000 words, but worst if less than that: COMPREPLY=($(awk -v cur="$3" -v pre="$2" -v suf="$4" '$0 ~ cur { print pre$0suf }' <<< "$1" )) COMPREPLY=($(printf -- "$2%s$4\n" $1 | grep "^$2$3")) Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> |

//////////////////////////////////////////////////////////////// Git - the stupid content tracker //////////////////////////////////////////////////////////////// "git" can mean anything, depending on your mood. - random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant. - stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang. - "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room. - "goddamn idiotic truckload of sh*t": when it breaks Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net. Please read the file INSTALL for installation instructions. See Documentation/gittutorial.txt to get started, then see Documentation/everyday.txt for a useful minimum set of commands, and Documentation/git-commandname.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with "man gittutorial" or "git help tutorial", and the documentation of each command with "man git-commandname" or "git help commandname". CVS users may also want to read Documentation/gitcvs-migration.txt ("man gitcvs-migration" or "git help cvs-migration" if git is installed). Many Git online resources are accessible from http://git-scm.com/ including full documentation and Git related tools. The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at http://news.gmane.org/gmane.comp.version-control.git/, http://marc.info/?l=git and other archival sites. The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
