When passed the "--literally" option, hash-object will allow any arbitrary string for its "-t" type option. Such objects are only useful for testing or debugging, as they cannot be used in the normal way (e.g., you cannot fetch their contents!). Let's drop this feature, which will eventually let us simplify the object-writing code. This is technically backwards incompatible, but since such objects were never really functional, it seems unlikely that anybody will notice. We will retain the --literally flag, as it also instructs hash-object not to worry about other format issues (e.g., type-specific things that fsck would complain about). The documentation does not need to be updated, as it was always vague about which checks we're loosening (it uses only the phrase "any garbage"). The code change is a bit hard to verify from just the patch text. We can drop our local hash_literally() helper, but it was really just wrapping write_object_file_literally(). We now replace that with calling index_fd(), as we do for the non-literal code path, but dropping the INDEX_FORMAT_CHECK flag. This ends up being the same semantically as what the _literally() code path was doing (modulo handling unknown types, which is our goal). We'll be able to clean up these code paths a bit more in subsequent patches. The existing test is flipped to show that we now reject the unknown type. The additional "extra-long type" test is now redundant, as we bail early upon seeing a bogus type. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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
