=== Gitorious environments ===
+
=== Plugins ===
 +
 
 +
Sugar Labs Gitorious instance uses downstream several plugins. All of them are enabled from {{Code|app/processors/push_event_processor.rb}} file and placed to {{code|lib/}} directory.
 +
 
 +
==== CIA ====
 +
 
 +
Notify http://cia.vc about all commits.
 +
 
 +
Plugin file:
 +
 
 +
lib/cia.rb
 +
 
 +
{{Code|gitorious.yml}} configuration:
 +
 
 +
cia: true
 +
 
 +
==== Patchwork ====
 +
 
 +
[http://patchwork.sugarlabs.org/ Patchwork] integration.
  
−
We do not have root on git.sugarlabs.org. Put the following aliases in your
+
Plugin file:
−
~/.bashrc to quickly switch to the Gitorious production, test and development
 
−
environments:
 
  
−
  alias gitorious='sudo su - gitorious'
+
  lib/patchwork.rb
−
alias gittest='sudo su - gittest'
 
−
alias gitdev='sudo su - gitdev'
 
−
alias db='mysql -h db1.osuosl.org -u sugarlabs_git -p  sugarlabs_git_dev'
 
  
−
=== Get a MySQL prompt ===
+
{{Code|gitorious.yml}} configuration:
−
type "db" at the prompt, then give the db password
 
−
from ~gitorious/config/database.yml
 
  
−
=== Change project owner ===
+
patchwork:
−
UPDATE projects SET user_id=(SELECT id FROM users WHERE login='jasg') WHERE slug='labyrinth';
+
  sugar:
 +
    url: "https://git.sugarlabs.org:0000000000000000000000000@patchwork.sugarlabs.org/xmlrpc/"
 +
    linkname: sugar
 +
    repositories:
 +
    - mainline
 +
    set_state: Accepted
 +
    find_states:
 +
    - New
 +
    - Under Review
  
−
=== Change repo owner ===
+
==== Pootle commits ====
−
UPDATE repositories SET user_id=(SELECT id FROM users WHERE login='jasg') WHERE name='mainline' AND project_id=(SELECT id FROM projects WHERE title='poll');
 
  
−
=== Add committer ===
+
Send notification emails on every pootle commit.
−
INSERT INTO committerships SET
 
−
        user_id=(select id from users where login='bernie'),
 
−
        repository_id=(SELECT id FROM repositories where
 
−
                project_id=(SELECT id FROM projects WHERE title='sugar') AND name='mainline'),
 
−
        kind=2, created_at=NOW(), updated_at=NOW();
 
  
−
=== Hijack account to reset password ===
+
Plugin file:
−
update users set email='YOUREMAIL' where login='USER';
 
  
−
Then make Gitorious send you a password reset email.
+
lib/emailer.rb
  
−
update users set email='OLDEMAIL' where login='USER';
+
{{Code|gitorious.yml}} configuration:
  
−
=== Zapping a user account ===
+
emailer: true
  
−
WARNING: to kill a user account, make sure you also remove *ALL* its associated records
+
=== Database tips ===
−
from all tables, or Gitorious will break in non-obvious ways.
 
  
−
SELECT id FROM users WHERE login='demian';
+
To make runtime changes in Gitorious database, follow regular Rails workflow - run {{Code|scripts/console}}:
−
DELETE FROM committers WHERE user_id=666;
 
−
DELETE FROM events WHERE user_id=666;
 
−
DELETE FROM comments WHERE user_id=666;
 
−
DELETE FROM merge_requests WHERE user_id=666;
 
−
DELETE FROM repositories WHERE user_id=666;
 
−
DELETE FROM projects WHERE user_id=666;
 
  
−
NOTE: tch pointed out that Rails applications often provide a higher-level method
+
cd /srv/gitorious/app
−
in class User which deletes the record and its associated entries. However, our
+
sudo -u gitorious RAILS_ENV=production script/console
−
deployed version of Gitorious does not seem to provide it.
 
  
−
=== Restart gitorious after code/config changes ===
+
It is regular Ruby console and all features, like {{Code|TAB}} completion, work. To tweak Gitorious data, just use its [http://gitorious.org/gitorious/mainline/trees/master/app/models model classes], e.g.:
−
  touch tmp/restart.txt
+
 
 +
# 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")
 +

repo.save!

 +
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")

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

git

/srv/gitorious/app

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:
su - gitorious

mkdir /srv/gitorious/repositories-mirror
mkdir /srv/gitorious/repositories-mirror
mkdir /srv/gitorious/tmp

git clone git://git.sugarlabs.org/sl-tweaks/gitorious.git /srv/gitorious/app

rsync --delete-after -PHAXhaxv $OLD_HOST:/srv/gitorious/repositories/ /srv/gitorious/repositories/
rsync --delete-after -PHAXhaxv $OLD_HOST:/srv/gitorious/app/public/system/ /srv/gitorious/app/public/system/
rsync --delete-after -PHAXhaxv $OLD_HOST:/srv/gitorious/ssh/.ssh/authorized_keys.bak /srv/gitorious/ssh/.ssh/authorized_keys

cd /srv/gitorious/app
rake db:migrate
rake ts:rebuild
rake mirror:symlinkedrepos
rake assets:clear
  • Start up Gitorious.
a2ensite git.sugarlabs.org
a2ensite cgit.sugarlabs.org
/etc/init.d/apache2 reload

/etc/init.d/gitorious-git start
/etc/init.d/gitorious-poller start
