# Demo script: manage local, gitolite-controlled, copies of upstream repos.
# Every time a client fetches such a repo, an upstream fetch happens, then the
# client fetch is completed. Optionally, you can be "nice" and impose a
# minimum delay between 2 fetches.
# See bottom of file for instructions and notes.
# ----------------------------------------------------------------------
repo=$2 # see doc/triggers.mkd for arguments
url=$(gitolite git-config $repo gitolite-options.upstream.url)
[ -z "$url" ] && exit 0 # exit if no url was specified
cd $GL_REPO_BASE/$repo.git
nice=$(gitolite git-config $repo gitolite-options.upstream.nice)
[ -n "$nice" ] && {
# exit if lastfetch was less than $nice minutes ago
find .gl.upstream.lastfetch -mmin -$nice | grep . >/dev/null && exit 0
touch .gl.upstream.lastfetch
}
git fetch -q "$url" '+refs/*:refs/*'
# ----------------------------------------------------------------------
# To install, add 'upstream' to the PRE_GIT trigger list in the rc file.
#
# Example setup to manage your own copy of the git repository:
# repo git
# R = @all
# RW+ my-company/ = @developers
# option upstream.url = git://git.kernel.org/pub/scm/git/git.git
# option upstream.nice = 120 # (optional) minimum 2 hours between fetches
# Notes:
# 1. we don't use a remote; due to refspec being +refs/*:refs/* we don't need one
# 2. please restrict local pushes, if any, to a namespace that the upstream won't use
# 3. if the upstream URL changes, change the conf file accordingly and push the admin repo
