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.
