Ævar Arnfjörð Bjarmason c95e3a3f0b send-email: move trivial config handling to Perl 
Optimize the startup time of git-send-email by using an amended
config_regexp() function to retrieve the list of config keys and
values we're interested in.

For boolean keys we can handle the [true|false] case ourselves, and
the "--get" case didn't need any parsing. Let's leave "--path" and
other "--bool" cases to "git config". I'm not bothering with the
"undef" or "" case (true and false, respectively), let's just punt on
those and others and have "git config --type=bool" handle it.

The "grep { defined } @values" here covers a rather subtle case. For
list values such as sendemail.to it is possible as with any other
config key to provide a plain "-c sendemail.to", i.e. to set the key
as a boolean true. In that case the Git::config() API will return an
empty string, but this new parser will correctly return "undef".

However, that means we can end up with "undef" in the middle of a
list. E.g. for sendemail.smtpserveroption in conjuction with
sendemail.smtpserver as a path this would have produce a warning. For
most of the other keys we'd behave the same despite the subtle change
in the value, e.g. sendemail.to would behave the same because
Mail::Address->parse() happens to return an empty list if fed
"undef". For the boolean values we were already prepared to handle
these variables being initialized as undef anyway.

This brings the runtime of "git send-email" from ~60-~70ms to a very
steady ~40ms on my test box. We now run just one "git config"
invocation on startup instead of 8, the exact number will differ based
on the local sendemail.* config. I happen to have 8 of those set.

This brings the runtime of t9001-send-email.sh from ~13s down to ~12s
for me. The change there is less impressive as many of those tests set
various config values, and we're also getting to the point of
diminishing returns for optimizing "git send-email" itself.

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
