Add a new environment variable to opt-in to the --full-name-hash option in 'git pack-objects'. This allows for extra testing of the feature without repeating all of the test scenarios. But this option isn't free. There are a few tests that change behavior with the variable enabled. First, there are a few tests that are very sensitive to certain delta bases being picked. These are both involving the generation of thin bundles and then counting their objects via 'git index-pack --fix-thin' which pulls the delta base into the new packfile. For these tests, disable the option as a decent long-term option. Second, there are two tests in t5616-partial-clone.sh that I believe are actually broken scenarios. While the client is set up to clone the 'promisor-server' repo via a treeless partial clone filter (tree:0), that filter does not translate to the 'server' repo. Thus, fetching from these repos causes the server to think that the client has all reachable trees and blobs from the commits advertised as 'haves'. This leads the server to providing a thin pack assuming those objects as delta bases. Changing the name-hash algorithm presents new delta bases and thus breaks the expectations of these tests. An alternative could be to set up 'server' as a promisor server with the correct filter enabled. This may also point out more issues with partial clone being set up as a remote-based filtering mechanism and not a repository-wide setting. For now, do the minimal change to make the test work by disabling the test variable. Signed-off-by: Derrick Stolee <stolee@gmail.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.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
