brian m. carlson cfb049119c gitweb: make hash size independent
Gitweb has several hard-coded 40 values throughout it to check for
values that are passed in or acquired from Git.  To simplify the code,
introduce a regex variable that matches either exactly 40 or exactly 64
hex characters, and use this variable anywhere we would have previously
hard-coded a 40 in a regex.

Add some helper functions which allow us to write tighter regexes that
match exactly the number of hex characters we're expecting.

Similarly, switch the code that looks for deleted diffinfo information
to look for either 40 or 64 zeros, and update one piece of code to use
this function.  Finally, when formatting a log line, allow an
abbreviated describe output to contain up to 64 characters.

GIT web Interface
=================

From the git version 1.4.0 gitweb is bundled with git.


Build time gitweb configuration
-------------------------------
There are many configuration variables which affect building gitweb (among
others creating gitweb.cgi out of gitweb.perl by replacing placeholders such
as `++GIT_BINDIR++` by their build-time values).

Building and installing gitweb is described in gitweb's INSTALL file
(in 'gitweb/INSTALL').


Runtime gitweb configuration
----------------------------
Gitweb obtains configuration data from the following sources in the
following order:

1. built-in values (some set during build stage),
2. common system-wide configuration file (`GITWEB_CONFIG_COMMON`,
   defaults to '/etc/gitweb-common.conf'),
3. either per-instance configuration file (`GITWEB_CONFIG`, defaults to
   'gitweb_config.perl' in the same directory as the installed gitweb),
   or if it does not exists then system-wide configuration file
   (`GITWEB_CONFIG_SYSTEM`, defaults to '/etc/gitweb.conf').

Values obtained in later configuration files override values obtained earlier
in above sequence.

You can read defaults in system-wide GITWEB_CONFIG_SYSTEM from GITWEB_CONFIG
by adding

  read_config_file($GITWEB_CONFIG_SYSTEM);

at very beginning of per-instance GITWEB_CONFIG file.  In this case
settings in said per-instance file will override settings from
system-wide configuration file.  Note that read_config_file checks
itself that the $GITWEB_CONFIG_SYSTEM file exists.

The most notable thing that is not configurable at compile time are the
optional features, stored in the '%features' variable.

Ultimate description on how to reconfigure the default features setting
in your `GITWEB_CONFIG` or per-project in `project.git/config` can be found
as comments inside 'gitweb.cgi'.

See also gitweb.conf(5) manpage.


Web server configuration
------------------------
Gitweb can be run as CGI script, as legacy mod_perl application (using
ModPerl::Registry), and as FastCGI script.  You can find some simple examples
in "Example web server configuration" section in INSTALL file for gitweb (in
gitweb/INSTALL).

See "Webserver configuration" and "Advanced web server setup" sections in
gitweb(1) manpage.
