Actualizar Weblate#

Docker image upgrades#

The official Docker image (see Instalar con Docker) has all Weblate upgrade steps integrated. There are typically no manual steps needed besides pulling latest version.

Instrucciones de actualización genéricas#

Before upgrading, please check the current Requisitos de software as they might have changed. Once all requirements are installed or updated, please adjust your settings.py to match changes in the configuration (consult settings_example.py for correct values).

Always check Instrucciones específicas de las versiones before upgrade. In case you are skipping some versions, please follow instructions for all versions you are skipping in the upgrade. Sometimes it’s better to upgrade to some intermediate version to ensure a smooth migration. Upgrading across multiple releases should work, but is not as well tested as single version upgrades.

Nota

It is recommended to perform a full database backup prior to upgrade so that you can roll back the database in case upgrade fails, see Respaldar y trasladar Weblate.

  1. Stop wsgi and Celery processes. The upgrade can perform incompatible changes in the database, so it is always safer to avoid old processes running while upgrading.

  2. Upgrade Weblate code.

    For pip installs it can be achieved by:

    pip install -U "Weblate[all]==version"
    

    Or, if you just want to get the latest released version:

    pip install -U "Weblate[all]"
    

    If you don’t want to install all of the optional dependencies do:

    pip install -U Weblate
    

    With Git checkout you need to fetch new source code and update your installation:

    cd weblate-src
    git pull
    # Update Weblate inside your virtualenv
    . ~/weblate-env/bin/pip install -e '.[all]'
    # Install dependencies directly when not using virtualenv
    pip install --upgrade -r requirements.txt
    # Install optional dependencies directly when not using virtualenv
    pip install --upgrade -r requirements-optional.txt
    
  3. New Weblate release might have new Dependencias de Python, please check if they cover features you want.

  4. Upgrade configuration file, refer to settings_example.py or Instrucciones específicas de las versiones for needed steps.

  5. Upgrade database structure:

    weblate migrate --noinput
    
  6. Collect updated static files (see Running server and Serving static files):

    weblate collectstatic --noinput --clear
    
  7. Compress JavaScript and CSS files (optional, see Compressing client assets):

    weblate compress
    
  8. If you are running version from Git, you should also regenerate locale files every time you are upgrading. You can do this by invoking:

    weblate compilemessages
    
  9. Verify that your setup is sane (see also Puesta en marcha de entorno de producción):

    weblate check --deploy
    
  10. Reinicie Celery (ver Tareas en segundo plano con Celery).

Instrucciones específicas de las versiones#

Distinto en la versión 5.0: Version specific instructions are now included in the release notes, see Weblate 5.5.

Upgrade from an older major version#

Upgrades across major versions are not supported. Always upgrade to the latest patch level for the initial major release. Upgrades skipping this step are not supported and will break.

  • If you are upgrading from the 2.x release, always first upgrade to 3.0.1.

  • If you are upgrading from the 3.x release, always first upgrade to 4.0.4.

  • If you are upgrading from the 4.x release, always first upgrade to 5.0.2.

Migrating from other databases to PostgreSQL#

If you are running Weblate on other dabatase than PostgreSQL, you should consider migrating to PostgreSQL as Weblate performs best with it. The following steps will guide you in migrating your data between the databases. Please remember to stop both web and Celery servers prior to the migration, otherwise you might end up with inconsistent data.

Crear una base de datos en PostgreSQL#

Suele ser una buena idea ejecutar Weblate en su propia base de datos, en una cuenta de usuario separada:

# If PostgreSQL was not installed before, set the main password
sudo -u postgres psql postgres -c "\password postgres"

# Create a database user called "weblate"
sudo -u postgres createuser -D -P weblate

# Create the database "weblate" owned by "weblate"
sudo -u postgres createdb -E UTF8 -O weblate weblate

Migrar a PostgreSQL con pgloader#

The pgloader is a generic migration tool to migrate data to PostgreSQL. You can use it to migrate Weblate database.

  1. Adjust your settings.py to use PostgreSQL as a database.

  2. Migrate the schema in the PostgreSQL database:

    weblate migrate
    weblate sqlflush | weblate dbshell
    
  3. Run the pgloader to transfer the data. The following script can be used to migrate the database, but you might want to learn more about pgloader to understand what it does and tweak it to match your setup:

    LOAD DATABASE
         FROM      mysql://weblate:password@localhost/weblate
         INTO postgresql://weblate:password@localhost/weblate
    
    WITH include no drop, truncate, create no tables, create no indexes, no foreign keys, disable triggers, reset sequences, data only
    
    ALTER SCHEMA 'weblate' RENAME TO 'public'
    ;
    

Migrar de Pootle#

As Weblate was originally written as replacement from Pootle, it is supported to migrate user accounts from Pootle. You can dump the users from Pootle and import them using importusers.
