In fetch-pack, the global variable save_commit_buffer is set to 0, but not restored to its original value after use. In particular, if show_log() (in log-tree.c) is invoked after fetch_pack() in the same process, show_log() will return before printing out the commit message (because the invocation to get_cached_commit_buffer() returns NULL, because the commit buffer was not saved). I discovered this when attempting to run "git log -S" in a partial clone, triggering the case where revision walking lazily loads missing objects. Therefore, restore save_commit_buffer to its original value after use. An alternative to solve the problem I had is to replace get_cached_commit_buffer() with get_commit_buffer(). That invocation was introduced in commita97934d("use get_cached_commit_buffer where appropriate", 2014-06-13) to replace "commit->buffer" introduced in commit3131b71("Add "--show-all" revision walker flag for debugging", 2008-02-13). In the latter commit, the commit author seems to be deciding between not showing an unparsed commit at all and showing an unparsed commit without the message (which is what the commit does), and did not mention parsing the unparsed commit, so I prefer to preserve the existing behavior.

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
