Jeff King b5b7b17b2e transport-helper: send "true" value for object-format option 
The documentation in gitremote-helpers.txt claims that after a helper
has advertised the "object-format" capability, Git may then send "option
object-format true" to indicate that it would like to hear which object
format the helper is using when it returns refs.

However, the code implementing this has always written just "option
object-format", without the extra "true" value. Nobody noticed in
practice or in the tests because the only two helpers we ship are:

  - remote-curl, which quietly converts missing values into "true". This
    goes all the way back to ef08ef9ea0 (remote-helpers: Support custom
    transport options, 2009-10-30), despite the fact that I don't think
    any other option has ever made use of it.

  - remote-testgit in t5801 does insist on having a "true" value. But
    since it sends the ":object-format" response regardless of whether
    it thinks the caller asked for it (technically breaking protocol),
    everything just works, albeit with an extra shell error:

      .../git/t/t5801/git-remote-testgit: 150: test: =: unexpected operator

    printed to stderr, which you can see running t5801 with --verbose.
    (The problem is that $val is the empty string, and since we don't
    double-quote it in "test $val = true", we invoke "test = true"
    instead).

When the documentation and code do not match, it is often good to fix
the documentation rather than break compatibility. And in this case, we
have had the mis-match since 8b85ee4f47 (transport-helper: implement
object-format extensions, 2020-05-25). However, the sha256 feature was
listed as experimental until 8e42eb0e9a (doc: sha256 is no longer
experimental, 2023-07-31).

It's possible there are some third party helpers that tried to follow
the documentation, and are broken. Changing the code will fix them. It's
also possible that there are ones that follow the code and will be
broken if we change it. I suspect neither is the case given that no
helper authors have brought this up as an issue (I only noticed it
because I was running t5801 in verbose mode for other reasons and
wondered about the weird shell error). That, coupled with the relative
new-ness of sha256, makes me think nobody has really worked on helpers
for it yet, which gives us an opportunity to correct the code before too
much time passes.

And doing so has some value: it brings "object-format" in line with the
syntax of other options, making the protocol more consistent. It also
lets us use set_helper_option(), which has better error reporting.

Note that we don't really need to allow any other values like "false"
here. The point is for Git to tell the helper that it understands
":object-format" lines coming back as part of the ref listing. There's
no point in future versions saying "no, I don't understand that".

To make sure everything works as expected, we can improve the
remote-testgit helper from t5801 to send the ":object-format" line only
if the other side correctly asked for it (which modern Git will always
do). With that test change and without the matching code fix here, t5801
will fail when run with GIT_TEST_DEFAULT_HASH=sha256.

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 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
