Jeff King 14eab817e4 pipe_command(): avoid xwrite() for writing to pipe If xwrite() sees an EAGAIN response, it will loop forever until the write succeeds (or encounters a real error). This is due to `ef1cf0167a` (xwrite: poll on non-blocking FDs, 2016-06-26), with the idea that we won't be surprised by a descriptor unexpectedly set as non-blocking. But that will make things awkward when we do want a non-blocking descriptor, and a future patch will switch pipe_command() to using one. In that case, looping on EAGAIN is bad, because the process on the other end of the pipe may be waiting on us before doing another read() on the pipe, which would mean we deadlock. In practice we're not supposed to ever see EAGAIN here, since poll() will have just told us the descriptor is ready for writing. But our Windows emulation of poll() will always return "ready" for writing to a pipe descriptor! This is due to `94f4d01932` (mingw: workaround for hangs when sending STDIN, 2020-02-17). Our best bet in that case is to keep handling other descriptors, as any read() we do may allow the child command to make forward progress (i.e., its write() finishes, and then it read()s from its stdin, freeing up space in the pipe buffer). This means we might busy-loop between poll() and write() on Windows if the child command is slow to read our input, but it's much better than the alternative of deadlocking. In practice, this busy-looping should be rare: - for small inputs, we'll just write the whole thing in a single write() anyway, non-blocking or not - for larger inputs where the child reads input and then processes it before writing (e.g., gpg verifying a signature), we may make a few extra write() calls that get EAGAIN during the initial write, but once it has taken in the whole input, we'll correctly block waiting to read back the data. - for larger inputs where the child process is streaming output back (like a diff filter), we'll likewise see some extra EAGAINs, but most of them will be followed immediately by a read(), which will let the child command make forward progress. Of course it won't happen at all for now, since we don't yet use a non-blocking pipe. This is just preparation for when we do.

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 with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). 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
