Derrick Stolee e2164742c9 fetch: add --negotiation-include option for negotiation Add a new --negotiation-include option to 'git fetch', which ensures that certain ref tips are always sent as 'have' lines during fetch negotiation, regardless of what the negotiation algorithm selects. This is useful when the repository has a large number of references, so the normal negotiation algorithm truncates the list. This is especially important in repositories with long parallel commit histories. For example, a repo could have a 'dev' branch for development and a 'release' branch for released versions. If the 'dev' branch isn't selected for negotiation, then it's not a big deal because there are many in-progress development branches with a shared history. However, if 'release' is not selected for negotiation, then the server may think that this is the first time the client has asked for that reference, causing a full download of its parallel commit history (and any extra data that may be unique to that branch). This is based on a real example where certain fetches would grow to 60+ GB when a release branch updated. This option is a complement to --negotiation-restrict, which reduces the negotiation ref set to a specific list. In the earlier example, using --negotiation-restrict to focus the negotiation to 'dev' and 'release' would avoid those problematic downloads, but would still not allow advertising potentially-relevant user branches. In this way, the 'include' version solves the problem I mention while allowing negotiation to pick other references opportunistically. The two options can also be combined to allow the best of both worlds. The argument may be an exact ref name or a glob pattern. Non-existent refs are silently ignored. This behavior is also updated in the ref matching logic for the related --negotiation-restrict option to match. The implementation outputs the requested objects as haves before the negotiator performs its own algorithm to choose the next haves. Use the new have_sent() interface to signal these have commits were sent before engaging with the negotiator's next() iterator. Also add --negotiation-include to 'git pull' passthrough options.

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
