Of the ref-filter callers, for-each-ref and git-branch both set the INCLUDE_BROKEN flag (but git-tag does not, which is a weird inconsistency). But now that GIT_REF_PARANOIA is on by default, that produces almost the same outcome for all three. The one exception is that GIT_REF_PARANOIA will omit dangling symrefs. That's a better behavior for these tools, as they would never include such a symref in the main output anyway (they can't, as it doesn't point to an object). Instead they issue a warning to stderr. But that warning is somewhat useless; a dangling symref is a perfectly reasonable thing to have in your repository, and is not a sign of corruption. It's much friendlier to just quietly ignore it. And in terms of robustness, the warning gains us little. It does not impact the exit code of either tool. So while the warning _might_ clue in a user that they have an unexpected broken symref, it would not help any kind of scripted use. This patch converts for-each-ref and git-branch to stop using the INCLUDE_BROKEN flag. That gives them more reasonable behavior, and harmonizes them with git-tag. We have to change one test to adapt to the situation. t1430 tries to trigger all of the REF_ISBROKEN behaviors from the underlying ref code. It uses for-each-ref to do so (because there isn't any other mechanism). That will no longer issue a warning about the symref which points to an invalid name, as it's considered dangling (and we can instead be sure that it's _not_ mentioned on stderr). Note that we do still complain about the illegally named "broken..symref"; its problem is not that it's dangling, but the name of the symref itself is illegal.

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). 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://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
