transport: don't flush when disconnecting stateless-rpc helper Since ba227857d2 (Reduce the number of connects when fetching, 2008-02-04), when we disconnect a git transport, we send a final flush packet. This cleanly tells the other side that we're done, and avoids the other side complaining "the remote end hung up unexpectedly" (though we'd only see that for transports that pass along the server stderr, like ssh or local-host). But when we've initiated a v2 stateless-connect session over a transport helper, there's no point in sending this flush packet. Each operation we've performed is self-contained, and the other side is fine with us hanging up between operations. But much worse, by sending the flush packet we may cause the helper to issue an entirely new request _just_ to send the flush packet. So we can incur an extra network request just to say "by the way, we have nothing more to send". Let's drop this extra flush packet. As the test shows, this reduces the number of POSTs required for a v2 ls-remote over http from 2 to 1. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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://public-inbox.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):
