Jakub Narebski da4b2432cc gitweb: selectable configurations that change with each request 
Allow selecting whether configuration file should be (re)parsed on each
request (the default, for backward compatibility with configurations that
change per session, see commit 7f425db (gitweb: allow configurations that
change with each request, 2010-07-30)), or whether should it be parsed only
once (for performance speedup for persistent environments, though currently
only FastCGI is able to make use of it, when flexibility is not important).

You can also have configuration file parsed only once, but have parts of
configuration (re)evaluated once per each request.

This is done by introducing $per_request_config variable: if set to code
reference, this code would be run once per request, while config file would
be parsed only once.  For example gitolite's contrib/gitweb/gitweb.conf
fragment mentioned in 7f425db could be rewritten as

  our $per_request_config = sub {
  	$ENV{GL_USER} = ($cgi && $cgi->remote_user) || "gitweb";
  };

to make use of this feature.

If $per_request_config is not a code reference, it is taken to be boolean
variable, to choose between running config file for each request
(flexibility), and running config file only once (performance in
persistent environments).

The default value for $per_request_config is 1 (true), which means that
old configuration that require to change per session (like gitolite's)
will keep working.

While at it, make it so evaluate_git_version() is run only once.

////////////////////////////////////////////////////////////////

	GIT - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, 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

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.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.

Please read the file INSTALL for installation instructions.

See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.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).

Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.

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. 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
http://marc.theaimsgroup.com/?l=git and other archival sites.

The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
