Taylor Blau e3ffc236a8 midx: verify duplicate pack entries by OID and offset 
A MIDX retains one entry per OID, while a non-strict pack index can
contain the same OID at several offsets. verify_midx_file() compares the
recorded offset with find_pack_entry_one(), which may return a different
member of that duplicate run and falsely report a valid MIDX as corrupt.

Check instead that the exact OID/offset pair exists anywhere in the
contiguous duplicate run in the source pack. That is the relevant
invariant: same-pack duplicates have no canonical representation, and
every matching physical copy is valid, including those recorded by
existing MIDXs.

This matches reader behavior. The OOFF chunk records the selected
(pack, offset), and midx_to_pack_pos() reconstructs its RIDX position
from that pair. If midx_pair_to_pack_pos() is given an unselected
duplicate offset, the lookup misses and its sole caller falls back from
partial reuse to normal packing. Readers therefore remain consistent
with whichever representation the MIDX records.

Write a MIDX over the existing duplicate-pack fixture, assert that its
selected offset differs from find_pack_entry_one(), and verify it. Then
run fsck as an application-level check.

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.adoc to get started, then see Documentation/giteveryday.adoc for a useful minimum set of commands, and Documentation/git-<commandname>.adoc 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.adoc (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
