John Cai 440c705ea6 cat-file: add --batch-command mode Add a new flag --batch-command that accepts commands and arguments from stdin, similar to git-update-ref --stdin. At GitLab, we use a pair of long running cat-file processes when accessing object content. One for iterating over object metadata with --batch-check, and the other to grab object contents with --batch. However, if we had --batch-command, we wouldn't need to keep both processes around, and instead just have one --batch-command process where we can flip between getting object info, and getting object contents. Since we have a pair of cat-file processes per repository, this means we can get rid of roughly half of long lived git cat-file processes. Given there are many repositories being accessed at any given time, this can lead to huge savings. git cat-file --batch-command will enter an interactive command mode whereby the user can enter in commands and their arguments that get queued in memory: <command1> [arg1] [arg2] LF <command2> [arg1] [arg2] LF When --buffer mode is used, commands will be queued in memory until a flush command is issued that execute them: flush LF The reason for a flush command is that when a consumer process (A) talks to a git cat-file process (B) and interactively writes to and reads from it in --buffer mode, (A) needs to be able to control when the buffer is flushed to stdout. Currently, from (A)'s perspective, the only way is to either 1. kill (B)'s process 2. send an invalid object to stdin. 1. is not ideal from a performance perspective as it will require spawning a new cat-file process each time, and 2. is hacky and not a good long term solution. With this mechanism of queueing up commands and letting (A) issue a flush command, process (A) can control when the buffer is flushed and can guarantee it will receive all of the output when in --buffer mode. --batch-command also will not allow (B) to flush to stdout until a flush is received. This patch adds the basic structure for adding command which can be extended in the future to add more commands. It also adds the following two commands (on top of the flush command): contents <object> LF info <object> LF The contents command takes an <object> argument and prints out the object contents. The info command takes an <object> argument and prints out the object metadata. These can be used in the following way with --buffer: info <object> LF contents <object> LF contents <object> LF info <object> LF flush LF info <object> LF flush LF When used without --buffer: info <object> LF contents <object> LF contents <object> LF info <object> LF info <object> LF Helped-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: John Cai <johncai86@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>		2022-02-18 11:21:46 -08:00

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). 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://lore.kernel.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):

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
