builtin/merge-base: free commit lists In several functions, we iterate through a commit list by assigning `result = result->next`. As a consequence, we lose the original pointer and eventually leak the list. Rewrite the loops so that we keep the original pointers, then call `free_commit_list()`. Various alternatives were considered: 1) Use `UNLEAK(result)` before the loop. Simple change, but not very pretty. These would definitely be new lows among our usages of UNLEAK. 2) Use `pop_commit()` when looping. Slightly less simple change, but it feels slightly preferable to first display the list, then free it. 3) As in this patch, but with `UNLEAK()` instead of freeing. We'd still go through all the trouble of refactoring the loop, and because it's not super-obvious that we're about to exit, let's just free the lists -- it probably doesn't affect the runtime much. In `handle_independent()` we can drop `result` while we're here and reuse the `revs`-variable instead. That matches several other users of `reduce_heads()`. The memory-leak that this hides will be addressed in the next commit. Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.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).
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 https://public-inbox.org/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.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
