Derrick Stolee c96060b0ce bundle: properly clear all revision flags 
The verify_bundle() method checks two things for a bundle's
prerequisites:

 1. Are these objects in the object store?
 2. Are these objects reachable from our references?

In this second question, multiple uses of verify_bundle() in the same
process can report an invalid bundle even though it is correct. The
reason is due to not clearing all of the commit marks on the commits
previously walked.

The revision walk machinery was first introduced in-process by
fb9a54150d (git-bundle: avoid fork() in verify_bundle(), 2007-02-22).
This implementation used "-1" as the set of flags to clear. The next
meaningful change came in 2b064697a5 (revision traversal: retire
BOUNDARY_SHOW, 2007-03-05), which introduced the PREREQ_MARK flag
instead of a flag normally controlled by the revision-walk machinery.

In 86a0a408b9 (commit: factor out
clear_commit_marks_for_object_array, 2011-10-01), the loop over the
array of commits was replaced with a new
clear_commit_marks_for_object_array(), but simultaneously the "-1" value
was replaced with "ALL_REV_FLAGS", which stopped un-setting the
PREREQ_MARK flag. This means that if multiple commits were marked by the
PREREQ_MARK in a previous run of verify_bundle(), then this loop could
terminate early due to 'i' going to zero:

	while (i && (commit = get_revision(&revs)))
		if (commit->object.flags & PREREQ_MARK)
			i--;

The flag clearing work was changed again in 63647391e6 (bundle: avoid
using the rev_info flag leak_pending, 2017-12-25), but that was only
cosmetic and did not change the behavior.

It may seem that it would be sufficient to add the PREREQ_MARK flag to
the clear_commit_marks() call in its current location. However, we
actually need to do it in the "cleanup:" step, since the first loop
checking "Are these objects in the object store?" might add the
PREREQ_MARK flag to some objects and then terminate without performing a
walk due to one missing object. By clearing the flags in all cases, we
avoid this issue when running verify_bundle() multiple times in the same
process.

Moving this loop to the cleanup step alone would cause a segfault when
running 'git bundle verify' outside of a repository, but this is because
of that error condition using "goto cleanup" when returning is perfectly
safe. Nothing has been initialized at that point, so we can return
immediately without causing any leaks.

This behavior is verified carefully by a test that will be added soon
when Git learns to download bundle lists in a 'git clone --bundle-uri'
command.

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 with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, http://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
