# From 6.1 to 6.2

## Notice
Security vulnerabilities CVE-2013-4490 and CVE-2013-4489 have been patched in the latest version of GitLab 6.2.

# You should update to 6.1 before installing 6.2 so all the necessary conversions are run.

### 0. Backup

It's useful to make a backup just in case things go south:
(With MySQL, this may require granting "LOCK TABLES" privileges to the GitLab user on the database version)

```bash
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
```

### 1. Stop server

    sudo service gitlab stop

### 2. Get latest code

```bash
cd /home/git/gitlab
sudo -u git -H git fetch --all
sudo -u git -H git checkout 6-2-stable # Latest version of 6-2-stable addresses CVE-2013-4489
# For GitLab Enterprise Edition: sudo -u git -H git checkout 6-2-stable-ee
```

### 3. Update gitlab-shell

```bash
cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v1.7.9 # Addresses multiple critical security vulnerabilities
```

### 4. Install additional packages

```bash
# Add support for lograte for better log file handling
sudo apt-get install logrotate
```

### 5. Install libs, migrations, etc.

```bash
cd /home/git/gitlab

# MySQL
sudo -u git -H bundle install --without development test postgres --deployment

#PostgreSQL
sudo -u git -H bundle install --without development test mysql --deployment


sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
sudo -u git -H bundle exec rake assets:clean RAILS_ENV=production
sudo -u git -H bundle exec rake assets:precompile RAILS_ENV=production
sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
```

### 6. Update config files

TIP: to see what changed in gitlab.yml.example in this release use next command: 

```
git diff 6-1-stable:config/gitlab.yml.example 6-2-stable:config/gitlab.yml.example
```

* Make `/home/git/gitlab/config/gitlab.yml` same as https://gitlab.com/gitlab-org/gitlab-ce/blob/6-2-stable/config/gitlab.yml.example but with your settings.
* Make `/home/git/gitlab/config/unicorn.rb` same as https://gitlab.com/gitlab-org/gitlab-ce/blob/6-2-stable/config/unicorn.rb.example but with your settings.
* Copy rack attack middleware config

```bash
sudo -u git -H cp config/initializers/rack_attack.rb.example config/initializers/rack_attack.rb
```
* Uncomment `config.middleware.use Rack::Attack` in `/home/git/gitlab/config/application.rb`
* Set up logrotate

```bash
sudo cp lib/support/logrotate/gitlab /etc/logrotate.d/gitlab
```

### 7. Update Init script

```bash
sudo rm /etc/init.d/gitlab
sudo curl --output /etc/init.d/gitlab https://raw.github.com/gitlabhq/gitlabhq/6-2-stable/lib/support/init.d/gitlab
sudo chmod +x /etc/init.d/gitlab
```

### 8. Start application

    sudo service gitlab start
    sudo service nginx restart

### 9. Check application status

Check if GitLab and its environment are configured correctly:

    sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production

To make sure you didn't miss anything run a more thorough check with:

    sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

If all items are green, then congratulations upgrade complete!

## Things went south? Revert to previous version (6.1)

### 1. Revert the code to the previous version
Follow the [`upgrade guide from 6.0 to 6.1`](6.0-to-6.1.md), except for the database migration 
(The backup is already migrated to the previous version)

### 2. Restore from the backup:

```bash
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
```
