Jeff King 753f6708d0 commit: avoid leaking already-saved buffer 
When we parse a commit via repo_parse_commit_internal(), if
save_commit_buffer is set we'll stuff the buffer of the object contents
into a cache, overwriting any previous value.

This can result in a leak of that previously cached value, though it's
rare in practice. If we have a value in the cache it would have come
from a previous parse, and during that parse we'd set the object.parsed
flag, causing any subsequent parse attempts to exit without doing any
work.

But it's possible to "unparse" a commit, which we do when registering a
commit graft. And since shallow fetches are implemented using grafts,
the leak is triggered in practice by t5539.

There are a number of possible ways to address this:

  1. the unparsing function could clear the cached commit buffer, too. I
     think this would work for the case I found, but I'm not sure if
     there are other ways to end up in the same state (an unparsed
     commit with an entry in the commit buffer cache).

  2. when we parse, we could check the buffer cache and prefer it to
     reading the contents from the object database. In theory the
     contents of a particular sha1 are immutable, but the code in
     question is violating the immutability with grafts. So this
     approach makes me a bit nervous, although I think it would work in
     practice (the grafts are applied to what we parse, but we still
     retain the original contents).

  3. We could realize the cache is already populated and discard its
     contents before overwriting. It's possible some other code could be
     holding on to a pointer to the old cache entry (and we'd introduce
     a use-after-free), but I think the risk of that is relatively low.

  4. The reverse of (3): when the cache is populated, don't bother
     saving our new copy. This is perhaps a little weird, since we'll
     have just populated the commit struct based on a different buffer.
     But the two buffers should be the same, even in the presence of
     grafts (as in (2) above).

I went with option 4. It addresses the leak directly and doesn't carry
any risk of breaking other assumptions. And it's the same technique used
by parse_object_buffer() for this situation, though I'm not sure when it
would even come up there. The extra safety has been there since
bd1e17e245 (Make "parse_object()" also fill in commit message buffer
data., 2005-05-25).

This lets us mark t5539 as leak-free.

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-<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).

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 and Documentation/CodingGuidelines).

Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).

To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.

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
