Use reference iteration rather than do_for_each_entry_in_dir() in the definition of commit_packed_refs(). Note that an internal consistency check that was previously done in `write_packed_entry_fn()` is not there anymore. This is actually an improvement: The old error message was emitted when there is an entry in the packed-ref cache that is not `REF_KNOWS_PEELED`, and when we attempted to peel the reference, the result was `PEEL_INVALID`, `PEEL_IS_SYMREF`, or `PEEL_BROKEN`. Since a packed ref cannot be a symref, `PEEL_IS_SYMREF` and `PEEL_BROKEN` can be ruled out. So we're left with `PEEL_INVALID`. An entry without `REF_KNOWS_PEELED` can get into the packed-refs cache in the following two ways: * The reference was read from a `packed-refs` file that didn't have the `fully-peeled` attribute. In that case, we *don't want* to emit an error, because the broken value is presumably a stale value of the reference that is now masked by a loose version of the same reference (which we just don't happen to be packing this time). This is a perfectly legitimate situation and doesn't indicate that the repository is corrupt. The old code incorrectly emits an error message in this case. (It was probably never reported as a bug because this scenario is rare.) * The reference was a loose reference that was just added to the packed ref cache by `files_packed_refs()` via `pack_if_possible_fn()` in preparation for being packed. The latter function refuses to pack a reference for which `entry_resolves_to_object()` returns false, and otherwise calls `peel_entry()` itself and checks the return value. So an entry added this way should always have `REF_KNOWS_PEELED` and shouldn't trigger the error message in either the old code or the new.

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.
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
