Database tips
To make runtime changes in Gitorious database, follow regular Rails workflow - run scripts/console:
cd /srv/gitorious/app sudo -u gitorious RAILS_ENV=production script/console
It is regular Ruby console and all features, like TAB completion, work. To tweak Gitorious data, just use its model classes, e.g.:
# search of particular object by its attributes
user = User.find_by_login("user")
project = Project.find_by_title("project")
# get object attributes
user.email
# change object attributes
project.owner = User.find_by_email("foo@bar")
project.save!
# destroy object and all its dependencies
user.destroy
# reset user password
user = User.find_by_email("user")
password_key = user.forgot_password!
Mailer.deliver_forgotten_password(user, password_key)
# add repository committer
committer = User.find_by_login("user")
repo = Repository::find_by_path("sugar/mainline")
repo.committerships.create_with_permissions!({:committer => committer}, (Committership::CAN_COMMIT))
# delete repository committer
committer = User.find_by_login("user")
repo = Repository::find_by_path("sugar/mainline")
repo.committerships = repo.committerships.select {|i| !i.members.include? committer }
# change repository owner
new_owner = User.find_by_login("user")
repo = Repository::find_by_path("sugar/mainline")
cs = repo.committerships.select {|i| i.committer == new_owner}.pop
cs.permissions = (Committership::CAN_ADMIN | Committership::CAN_COMMIT | Committership::CAN_REVIEW)
cs.save!
repo.owner = new_owner
repo.save!
# move repository to another project
new_project = Project.find_by_title('sl-tweaks')
repo = Repository::find_by_path("sat-solver/mainline")
repo.project = new_project
repo.name = "sat-solver"
repo.save!
# check users permissions for particular repository
repo = Repository::find_by_path("pukllanapac/mainline")
repo.committerships.each {|i| puts "#{User.find(i.committer_id).login} review=#{i.permissions & Committership::CAN_REVIEW > 0}"}
repo.committerships.each {|i| puts "#{User.find(i.committer_id).login} commit=#{i.permissions & Committership::CAN_COMMIT > 0}"}
repo.committerships.each {|i| puts "#{User.find(i.committer_id).login} admin=#{i.permissions & Committership::CAN_ADMIN > 0}"}
TODO
Current gitorious patch doesn't handle renaming repositories properly and doesn't update symliks in /srv/gitorious/repos-by-name. For now, run code to recreate symlinks:
Repository::find_each {|i| s='/srv/gitorious/repos/' + i.real_gitdir; d='/srv/gitorious/repos-by-name/' + i.gitdir; FileUtils.makedirs(File.dirname(d)) if !File.exist?(File.dirname(d)); File.symlink(s, d) if !File.exists? d}
Upgrade notes

After pulling new sources, migrate database:
cd /srv/gitorious/app/ sudo -u gitorious RAILS_ENV=production rake db:migrate
To restart only Web application, instead of restarting the daemon, call:
touch /srv/gitorious/app/tmp/restart.txt
Hardware migration
Disable servers of both hosts.
mv /srv/gitorious/ssh/.ssh/authorized_keys{,.bak}
a2dissite git.sugarlabs.org
a2dissite cgit.sugarlabs.org
/etc/init.d/apache2 reload
/etc/init.d/gitorious-git stop
/etc/init.d/gitorious-poller stop
/etc/init.d/gitorious-sphinx stop
/etc/init.d/gitorious-stomp stop
On old server.
- Dump MySQL database:
mysqldump -u root -h localhost -p gitorious | xz > dump.slq.xz
On new server.
- Create MySQL user and database for Gitorious:
GRANT ALL PRIVILEGES ON *.* TO 'gitorious'@'localhost' IDENTIFIED BY '<insert password>' WITH GRANT OPTION; FLUSH PRIVILEGES; CREATE DATABASE gitorious;
- Make preparations from root user:
useradd gitorious -d /srv/gitorious/ssh -m cat >> /srv/gitorious/ssh/.profile <<EOF export RAILS_ENV=production cd /srv/gitorious/app EOF xzcat dump.slq.xz | mysql -u root -p -D gitorious
- Make preparations from gitorious user:
