Jeff King 7ed76b4eb2 commit-graph: factor out chain opening function 
The load_commit_graph_chain() function opens the chain file and all of
the slices of graph that it points to. If there is no chain file (which
is a totally normal condition), we return NULL. But if we run into
errors with the chain file or loading the actual graph data, we also
return NULL, and the caller cannot tell the difference.

The caller can check for ENOENT for the unremarkable "no such file"
case. But I'm hesitant to assume that the rest of the function would
never accidentally set errno to ENOENT itself, since it is opening the
slice files (and that would mean the caller fails to notice a real
error).

So let's break this into two functions: one to open the file, and one to
actually load it. This matches the interface we provide for the
non-chain graph file, which will also come in handy in a moment when we
fix some bugs in the "git commit-graph verify" code.

Some notes:

  - I've kept the "1 is good, 0 is bad" return convention (and the weird
    "fd" out-parameter) used by the matching open_commit_graph()
    function and other parts of the commit-graph code. This is unlike
    most of the rest of Git (which would just return the fd, with -1 for
    error), but it makes sense to stay consistent with the adjacent bits
    of the API here.

  - The existing chain loading function will quietly return if the file
    is too small to hold a single entry. I've retained that behavior
    (and explicitly set ENOENT in the opener function) for now, under
    the notion that it's probably valid (though I'd imagine unusual) to
    have an empty chain file.

There are two small behavior changes here, but I think both are strictly
positive:

  1. The original blindly did a stat() before checking if fopen()
     succeeded, meaning we were making a pointless extra stat call.

  2. We now use fstat() to check the file size. The previous code using
     a regular stat() on the pathname meant we could technically race
     with somebody updating the chain file, and end up with a size that
     does not match what we just opened with fopen(). I doubt anybody
     ever hit this in practice, but it may have caused an out-of-bounds
     read.

We'll retain the load_commit_graph_chain() function which does both the
open and reading steps (most existing callers do not care about seeing
errors anyway, since loading commit-graphs is optimistic).

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
