Elijah Newren 7db118303a unpack_trees: fix breakage when o->src_index != o->dst_index 
Currently, all callers of unpack_trees() set o->src_index == o->dst_index.
The code in unpack_trees() does not correctly handle them being different.
There are two separate issues:

First, there is the possibility of memory corruption.  Since
unpack_trees() creates a temporary index in o->result and then discards
o->dst_index and overwrites it with o->result, in the special case that
o->src_index == o->dst_index, it is safe to just reuse o->src_index's
split_index for o->result.  However, when src and dst are different,
reusing o->src_index's split_index for o->result will cause the
split_index to be shared.  If either index then has entries replaced or
removed, it will result in the other index referring to free()'d memory.

Second, we can drop the index extensions.  Previously, we were moving
index extensions from o->dst_index to o->result.  Since o->src_index is
the one that will have the necessary extensions (o->dst_index is likely to
be a new index temporary index created to store the results), we should be
moving the index extensions from there.

Git - fast, scalable, distributed revision control system

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):

  • 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
