+# DESCRIPTION:
-# To anyone except pingou: these aren't the droids you are looking for. Move along.
+# This program is meant to re-compile the access rules (and 'config' or
+# 'option' lines) of exactly ONE actual repo (i.e., not a repo group or a
+# repo pattern).
+# MOTIVATION:
-use strict;
-use warnings;
+# Fedora has a huge number of repos, as well as lot of churn in permissions.
+# The combination of having a large conf *and* frequent compiles were not
+# working out, hence this solution. Not sure if any others have such a
+# situation, so it's a standalone program, separate from "core" gitolite,
+# shipped in "contrib" instead of "src".
+
+# SETUP:
+
+# It expects to run as a gitolite sub-command, which means you will need to
+# copy it from contrib to src/commands, or the equivalent location inside
+# LOCAL_CODE; see non-core.html in the docs for details.
+
+# INVOCATION:
+
+# It takes one argument: the name of a file that contains the new ruleset
+# you want to use. (This cannot be STDIN or "-" or something).
-# This program is meant to re-compile the access rules (and 'config' or
-# 'option' lines) of exacttly ONE repo.
+# example:
+#
+# gitolite compile-1 <file-containing-rules-for-exactly-one-repo>
-# It expects to run as a gitolite sub-command, that is:
-# gitolite compile-1 $single_repo_conf_file
+# WARNING:
-# It takes one argument: the name of a file that contains the new ruleset you
-# want to use. The file must contain exactly one 'repo' line, with exactly
-# one repo name, followed by the rules, configs, and options for that repo in
-# the normal gitolite.conf syntax.
+# If the main gitolite.conf changes significantly (specifically, if the
+# number of effective rules in it increase quite a bit), you may have to run
+# this command on ALL repos to update their individual gl-conf files.
+#
+# (TBD: explain this in more concrete terms)
-# IMPORTANT CAVEATS ARE DISCUSSED AT THE END OF THIS FILE. PLEASE READ!
+# ----------------------------------------------------------------------
+# THERE IS NO ERROR CHECKING ON THE WARNING ABOVE, NOR ON THE ASSUMPTIONS AND
+# REQUIREMENTS BELOW. PLEASE USE CAREFULLY!
+# ----------------------------------------------------------------------
-# THERE IS NO ERROR CHECKING ON THESE CAVEATS. PLEASE USE CAREFULLY!
+# ASSUMPTIONS/REQUIREMENTS:
+
+# The file given must contain exactly one 'repo' line, with exactly one repo
+# name, followed by the rules, configs, and options for that repo in the
+# normal gitolite.conf syntax.
+
+# The file must not have any group definitions, though it may use group
+# definitions already setup in the main gitolite.conf file.
+
+# Rules for this repo need not be already defined in the main gitolite.conf.
+# If they are, they will cease to have any effect once you run this command
+# - only the rules you supply in the file passed to this command will apply,
+# and they will be considered to be placed at the end of gitolite.conf.
+
+# If the repo does not exist, it must be first created using:
+#
+# GL_USER=admin gitolite create <reponame>
+#
+# where <reponame> is the gitolite-style name (i.e., "foo", not "foo.git" or
+# "~/repositories/foo" or "~/repositories/foo.git")
+#
+# This, of course, requires the main gitolite.conf to have the following
+# lines at the top:
+#
+# repo [A-Za-z].*
+# C = admin
+
+# Any change to the main gitolite.conf is followed by a full 'gitolite
+# compile'; i.e., ~/.gitolite/conf/gitolite.conf-compiled.pm, the main
+# "compiled" conf file, is consistent with the latest gitolite.conf.

-__END__
-
-This program is meant to do one thing, and one thing only: re-compile the
-rules for a single repo quickly and efficiently.
-
-CAVEATS:
-
-Apart from the requirements listed at the top, there are some things to watch for.
-
-Before we do that, let's define some terms for ease of discussion.
-
-* "named repos" -- repos that are explicitly named in gitolite.conf; e.g.
-
- repo foo bar baz
- ...
-
-* "other repos" -- repos that are not "named". Usually, they are defined
- via a group definition or a regex; e.g.
-
- repo @all
- ...
-
- @g1 = foo bar baz
- repo @g1
- ...
-
- repo fo[a-z].*
- ...
-
-Now the caveats:
-
-1. You can only use this to recompile rules for named repos, not for other
- repos.
-
-2. The repo must be defined only once in gitolite.conf. I.e., it's rules
- must NOT be split up across multiple sections or files, with other repos
- rules intervening in between. (Normal gitolite lets you do that, but that
- won't work with this code).
-
-3. All the "named repos" which you might ever want to single-compile in
- future, must be placed at the end of gitolite.conf. Do not place any
- "other repo" definitions after them.
-
- (This is a somewhat conservative restriction; there are situations in
- which it can be violated but it's hard to explain. Your current config
- seems to satisfy this constraint so I won't bother detailing how to get
- around it! Ask me on email if needed.)
