Fedora's config has over 11,000 repositories and the compiled config
file is over 20 MB in size. Although negligible on a server class
machine, on my laptop just parsing this file takes a good 2.5 seconds.
Even if you use GL_ALL_READ_ALL (see a couple of commits before this
one) to remove the overhead for 'read's, that's still a pretty big
overhead for writes. And GL_ALL_READ_ALL is not really a solution for
most people anyway.
With this commit, using GL_BIG_CONFIG adds another optimisation; see
doc/big-config.mkd for details (look for the word "split config" to find
the section that talks about it).
----
Implementation notes:
- the check for GL_NO_CREATE_REPOS has moved *into* the loop (which it
completely bypassed earlier) so that write_1_compiled_conf can be
called on each item
The old method of passing in usergroup info had some problems, which are
now fixed. It is also much easier to use now -- no more "wrapper"
script, plus it should work identially whether you use sshd or httpd.
See doc/big-config.mkd for details on the new method.
----
Notes on problems with the old method:
The old method for passing in usergroup info consisted of tacking them
on as extra arguments to gl-auth-command, after the username.
However, there are some problems with this method.
Some actions in gitolite look for permissions for users other than the
invoking user. Determining permissions for gitweb and daemon is one.
An admin asking for "info" on some other user, is another.
However, the list of groups sent in via the command line
pertains only to the invoking user, so these actions don't work
correctly. They may even pick up the wrong permissions.
What it all boils down to is that we need group information for any user
dynamically, instead of being passed a (static) list just for the
invoking user.
- all anchors prefixed by AUTO_ now
- some bad links fixed (maybe still a few I didn't catch)
- misc wording changes/additions (support section to README,
"technical skills" section to install doc, etc).
people will NOT read documentation, especially the bloody install
documentation. I'm about ready to throw in the towel and declare
gitolite unsupported, take-it-or-leave-it.
But I'm making one last attempt to refocus the install doc to better
suit the "I know I'm very smart and I dont have to read docs so it's
clearly your fault that I am not able to install gitolite" crowd.
As a bonus, though, I ended up making proper, hyper-linked, TOCs for
most of the docs, and moved a whole bunch of stuff around. Also finally
got some of the ssh stuff over from my git-notes repo because it really
belongs here.
