Jeff King 249e8dc73e refs/files-backend: handle packed transaction prepare failure
In files_transaction_prepare(), if we have to delete some refs, we use a
subordinate packed_transaction to do so. It's rare for that
sub-transaction's prepare step to fail, since we hold the packed-refs
lock. But if it does, we trigger a BUG() due to these steps:

  - we've attached the packed transaction to the files transaction as
    backend_data->packed_transaction

  - when the prepare step fails, the packed transaction cleans itself
    up, putting itself into the CLOSED state

  - the error value from preparing the packed transaction lets us know
    in files_transaction_prepare() that we should also clean up and
    return an error. We call files_transaction_cleanup(), which tries to
    abort backend_data->packed_transaction. Since it's already CLOSED,
    that triggers an assertion in ref_transaction_abort().

We can fix that by disconnecting the packed transaction from the outer
files transaction, and then free-ing (not aborting!) it ourselves.

A few other options/alternatives I considered:

  - we could just make it a noop to abort a CLOSED transaction. But that
    seems less safe, since clearly this code expects (and enforces) a
    particular set of state transitions.

  - we could have files_transaction_cleanup() selectively call abort()
    vs free() based on the state of the on the packed transaction.
    That's basically a more restricted version of the above, but also
    potentially unsafe.

  - instead of disconnecting backend_data->packed_transaction on error,
    we could wait to install it until we successfully prepare. That
    might make the flow a little simpler, but it introduces a hassle.
    Earlier parts of files_transaction_prepare() that encounter an error
    will jump to the cleanup label, and expect that cleaning up the
    outer transaction will clean up the packed transaction, too. We'd
    have to adjust those sites to clean up the packed transaction.

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.

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
