README.UPDATERS

For Updaters from OBS 2.10 to OBS 2.11
======================================

Note: Update from OBS 2.5 should also work, but it is not fully tested.
      A direct update from OBS 2.4 or older will not work.
      It's recommended to wait for all pending delayed jobs to be processed before
      creating a DB dump or running the migrations.
      To see the number of pending delayed jobs run

        cd /srv/www/obs/api
        bin/bundle exec bin/rails r -e production "puts Delayed::Job.count" RAILS_ENV=production

  1) Remove the OBS 2.10 Repository

        zypper rr OBS:Server:2.10

  2) Add the OBS 2.11 Repository and update repository cache

        zypper ar http://download.opensuse.org/repositories/OBS:/Server:/2.11/$YOUR_DISTRIBUTION/OBS:Server:2.11.repo
        zypper ref

  3) Update packages

        zypper dup --from OBS_Server_2.11

    NOTE: You may need to switch also your base distribution to a newer version. Adapt all repositories for that and do an

        zypper dup

      instead of the above command

  4) Migrate database

        cd /srv/www/obs/api/
        RAILS_ENV="production" bin/rails db:migrate:with_data

  5) Change to ruby3.1

        edit /etc/apache2/conf.d/mod_passenger.conf:

        PassengerRuby "/usr/bin/ruby.ruby3.1"

  6) Reboot your system to restart all OBS components


For Updaters from OBS 2.9 to OBS 2.10
=====================================

Note: Update from OBS 2.5 should also work, but it is not fully tested.

      creating a DB dump or running the migrations.
      To see the number of pending delayed jobs run

        cd /srv/www/obs/api
        bin/bundle exec bin/rails r -e production "puts Delayed::Job.count" RAILS_ENV=production


  1) The format of the OBS options.yml is now distinguishing between Rails environments.
     Please run following commands:

         cd /srv/www/obs/api/
         RAILS_ENV=production bin/rake migrate_options_yml

  2) Remove the OBS 2.9 Repository

        zypper rr OBS:Server:2.9

  3) Add the OBS 2.10 Repository and update repository cache

        zypper ref

  4) Update packages

        zypper dup --from OBS_Server_2.10

    NOTE: You may need to switch also your base distribution to a newer version. Adapt all repositories for that
          and do an

        zypper dup

      instead of the above command

  5) Migrate database

        cd /srv/www/obs/api/
        RAILS_ENV="production" bin/rails db:migrate:with_data

  7) Reboot your system to restart all OBS components


For Updaters to OBS 2.9 from OBS 2.8
====================================

Note: Update from OBS 2.5 should also work, but is untested.
      A direct update from OBS 2.4 or older will not work.
      It's recommended to wait for all pending delayed jobs to be processed before
      creating a DB dump or running the migrations.
      To see the number of pending delayed jobs run
      `(cd /srv/www/obs/api; bundle exec rails r -e production "puts Delayed::Job.count")`

  1) Remove the OBS 2.8 Repository

        systemctl enable obsdeltastore
        systemctl start obsdodup
        systemctl start obsdeltastore

     obsdodup must run on each backend server which runs also a repostory server.
     obsdeltastore must run where the src server is running.


For Updaters to OBS 2.6 from OBS 2.5
====================================

Appliance users can just do a package update and reboot or use the
new appliance image to update their configurations.

In case the installation is not done via packages all
rubygems according to Gemfile need to get installed.

 1) Database migration

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate
    # chown -R wwwrun.www log tmp

 2) Restart following services in this order

      * apache2

      * obsapidelayed

      * memcached

    The backend daemons are restarting automatically on update.


For Updaters to OBS 2.5 from OBS 2.4
====================================

Appliance users can just do a package update and reboot or use the
new appliance image to update their configurations.

In case the installation is not done via packages all
rubygems according to Gemfile need to get installed.

Biggest change setup wise is the unification of API and WEBUI instance.
This means only one rails stack is running which can be used for both,
browsing via web browser and also as api to be used with osc.

In case you do not use the obs apache configuration which comes with
package, you need to disable your webui configuration.

Users which used port 444 as api have to reconfigure their clients to
use port 443 now.

 1) Database migration

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate
    # chown -R wwwrun.www log tmp

 2) Restart memcached after database migration to wipe possible broken
    cache data.

 3) configuration settings moved from various palces to unique /configuration
    api route as much as possible to allow a uniq configuration through all
    OBS frontend and backend parts. The following settings have been migrated:

    from BSConfig.pm:
      obsname              => name
      enforce_project_keys => enforce_project_keys
      download_on_demand   => download_on_demand
      http_proxy           => http_proxy
      no_proxy             => no_proxy

    from api options.yml:
      new_user_registration             => registration
      allow_anonymous                   => anonymous
      default_access_disabled           => default_access_disabled
      allow_user_to_create_home_project => allow_user_to_create_home_project
      disallow_group_creation_with_api  => disallow_group_creation
      change_passwd                     => change_password
      download_url                      => download_url
      ymp_url                           => ymp_url
      http_proxy                        => http_proxy

    from webui options.yml:
      hide_private_options => hide_private_options
      use_gravatar         => gravatar
      http_proxy           => http_proxy
      download_url         => download_url
      bugzilla_host        => bugzilla_url
      theme                => theme


 4) api interface configuration must be configured in /srv/www/obs/api/config/options.yml
    now. Ensure that at least the following parameters are configured there:

      frontend_host:
      frontend_port:
      frontend_protocol:

 5) Non-Appliance users who do not have obsapisetup init script running need
    also to call the following once to have a working search:

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails ts:rt:index

For Updaters to OBS 2.4 from OBS 2.3
====================================

Appliance users can just do a package update and reboot or use the
new appliance image to update their configurations.

Other installations need merge manually configurations
as described below (This is required due to the Rails 2.x
to Rails 3.x switch).

In case the installation is not done via packages all
rubygems according to Gemfile need to get installed.

Please check the following files:

 1) database driver needs to be changed to "mysql2" in /srv/www/obs/api/config/database.yml
    This is usally done automatically by the package.

 2) all config options with capital letters have been moved from
      /srv/www/obs/.../config/environments/production.rb
    to small letter variables in
      /srv/www/obs/.../config/options.yml

    The old production.rb files will not work anymore, please transfer your
    configuration in the new file (available as production.rb.rpmnew) and
    the options.yml. Do not forget to rename production.rb.rpmnew to production.rb.

 3) Database migration

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate
    # chown -R wwwrun.www log tmp

    # cd /srv/www/obs/webui/
    # RAILS_ENV="production" rails db:migrate
    # chown -R wwwrun.www log tmp

 4) Restart memcached after database migration to wipe possible broken
    cache data.

For Updaters to OBS 2.3 from OBS 2.1
====================================

1) Database migration

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate
    # chown -R wwwrun.www log tmp

    # cd /srv/www/obs/webui/
    # RAILS_ENV="production" rails db:migrate
    # chown -R wwwrun.www log tmp

2) Switch from lighttpd to apache2

   The default httpd is apache2 since OBS 2.3. lighttpd should still work, but
   we recommend to switch to apache to get a maintained base and load
   optimizations.

   Please read the section 3 from README.SETUP file to learn how to configure
   apache.


For Updaters to OBS 2.1 from OBS 2.0
====================================

1) Database migration

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate
    # chown -R lighttpd.lighttpd log

    # cd /srv/www/obs/webui/
    # RAILS_ENV="production" rails db:migrate
    # chown -R lighttpd.lighttpd log

2) Build backend source database

   On the system, where bs_srcserver is running you need to build the
   source database to get an index of existing linked packages.

    # su -c "bs_admin --update-source-db"

3) OPTIONAL step

   It is recommended to use a MySQL database for OBS webui from now on.
   The default has changed away from sqlite, but it does still work, except from
   occasional connect errors between lighttpd/ruby and sqlite.

   To setup the MySQL webui database instead of a sqlite one do the following
   steps:

   * Create the database:
      # mysql -u root -p
      mysql> create database webui_production;
      mysql> GRANT all privileges ON webui_production.* TO 'obs'@'%', 'obs'@'localhost';
      mysql> FLUSH PRIVILEGES;
      mysql> quit

   * Configure your MySQL user and password in the "production:" section
     of the webui config:

        /srv/www/obs/webui/config/database.yml

     A template for this file can be found in same directory as "database.yml.example".

   * populate the database
      # cd /srv/www/obs/webui/
      # sudo RAILS_ENV="production" rails db:schema:load db:seed
      # sudo chown lighttpd.lighttpd log/*



For Updaters to OBS 2.0 from OBS 1.7
====================================

NOTE: Do not update from the special MeeGo 1.8 release yet. You will miss
      features and run into database migration errors.
      You need to wait for OBS 2.1.

After running the package update to obs-* 2.0 packages you need to do the
following steps manually:

1) Database migration

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate
    # chown -R lighttpd.lighttpd log

    # cd /srv/www/obs/webui/
    # RAILS_ENV="production" rails db:migrate
    # chown -R lighttpd.lighttpd log

2) Default distribution configuration
   The default targets are now defined in one place on the api.
   Create the default config via

    # cd /srv/www/obs/api/files/
    # cp distributions.xml.template distributions.xml

3) restart all services.
   easiest is maybe to restart your entire system.


For Updaters from OBS 1.6
=========================

1) Rename of frontend and webclient
   - The former called "frontend" has been renamed to "api"
   - The former called "webclient" has been renamed to "webui"

   Following this change quite a number of places have been adapated,
   for example the directory names below /src/www/obs. The packages shall
   convert this rename nicely.

   Your former used database config, most likely using "frontend_production"
   database is not touched by this, the server will still use this one.

2) Required rails migrate update

  When the obs-api package has been updated, it is required to upgrade
  the database. Therefore, you should do

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate

  and

    # cd /srv/www/obs/webui/
    # RAILS_ENV="production" rails db:migrate

3) Enable the new services

  In case you use the package signing, you need to run the new bs_signer
  process. This has been split out of bs_repserver for better scalability.

    # insserv obssigner
    # rcobs_signer start

  You may want to run also the new bs_warden daemon, this monitors the
  build hosts and restarts jobs, in case a build host is not responding
  correctly anymore:

    # insserv obswarden
    # rcobswarden start

  The experimental new obsserver daemon can optionally be started and be used
  for automatic file downloads (or own source services)

    # insserv obsservice
    # rcobsservice start

  To update api and webui informations, you need to start the following processes

    # insserv obsapidelayed
    # rcobsapidelayed start

  By default, you should *NOT* start the following services. These are intended
  to autoconfigure services on the OBS Appliance image based on existing LVM
  volumes and your local network setup. They will replace local configuration
  files on each boot.

    # obsstoragesetup
    # obsapisetup

For Updaters from OBS 0.9.x releases
====================================

1) Define download URL in rails config.

The new introduced "DOWNLOAD_URL" need to be defined in your settings
below /srv/www/obs/webui/config/environments/ directory.
If you do not have a download server, simply define

DOWNLOAD_URL = nil

in your configuration.

2) Recommended rails migrate update

A rails migrate is recommended, but not neccessary. It would reimport
buginfo flags from the backend to fix broken usage in api before.

When the obs-api package has been updated, it might be required to
upgrade the database. Therefore, you should do

    # cd /srv/www/obs/api/
    # RAILS_ENV="production" rails db:migrate

after updating obs-api.

Updater from before 0.9 release
===============================

Updaters of build server versions before 0.9 needs to rename their databases from
"development" to production. This can be performed by the following steps:

      # mysql -u root -p
      mysql> create database api_production;
      mysql> create database webui_production;
      mysql> quit
      # mysqldump -p api_development > DUMP
      # mysql -u root -p api_production < DUMP
      # mysqldump -p webui_development > DUMP
      # mysql -u root -p webui_production < DUMP

All Updaters needs to update their database schema in any case by running the
following commands:

      # cd /srv/www/obs/api/
      # RAILS_ENV="production" rails db:migrate
