Aktualizacja Weblate

Uaktualnienia obrazów platformy Docker

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

Ogólne instrukcje dotyczące aktualizacji

Before upgrading, please check the current Wymagania dotyczące oprogramowania 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 Instrukcje dotyczące poszczególnych wersji 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.

Informacja

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 Tworzenie kopii zapasowych i przenoszenie 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. Aktualizacja kodu Weblate.

    For pip installs it can be achieved by:

    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 .
    # 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 Opcjonalne zależności, please check if they cover features you want.

  4. Upgrade configuration file, refer to settings_example.py or Instrukcje dotyczące poszczególnych wersji for needed steps.

  5. Aktualizacja struktury bazy danych:

    weblate migrate --noinput
    
  6. Collect updated static files (see Uruchamianie serwera and Obsługa plików statycznych):

    weblate collectstatic --noinput --clear
    
  7. Compress JavaScript and CSS files (optional, see Kompresowanie zasobów klienta):

    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 Instalacja produkcyjna):

    weblate check --deploy
    
  10. Uruchom ponownie workera Celery (patrz Zadania w tle korzystające z Celery).

Instrukcje dotyczące poszczególnych wersji

Aktualizacja z 2.x

If you are upgrading from 2.x release, always first upgrade to 3.0.1 and then continue upgrading in the 3.x series. Upgrades skipping this step are not supported and will break.

Aktualizacja z 3.x

If you are upgrading from 3.x release, always first upgrade to 4.0.4 or 4.1.1 and then continue upgrading in the 4.x series. Upgrades skipping this step are not supported and will break.

Aktualizacja z 4.0 do 4.1

Please follow Ogólne instrukcje dotyczące aktualizacji in order to perform update.

Istotne zmiany konfiguracji lub zależności:

  • There are several changes in settings_example.py, most notable middleware changes, please adjust your settings accordingly.

  • There are new file formats, you might want to include them in case you modified the WEBLATE_FORMATS.

  • There are new quality checks, you might want to include them in case you modified the CHECK_LIST.

  • There is change in DEFAULT_THROTTLE_CLASSES setting to allow reporting of rate limiting in the API.

  • There are some new and updated requirements.

Upgrading from Python 2 to Python 3

Weblate no longer supports Python older than 3.6. In case you are still running on older version, please perform migration to Python 3 first on existing version and upgrade later. See Upgrading from Python 2 to Python 3 in the Weblate 3.11.1 documentation.

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.

Tworzenie bazy danych w PostgreSQL

It is usually a good idea to run Weblate in a separate database, and separate user account:

# 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

Migracja przy użyciu zrzutów Django JSON

The simplest approach for migration is to utilize Django JSON dumps. This works well for smaller installations. On bigger sites you might want to use pgloader instead, see Migrating to PostgreSQL using pgloader.

  1. Add PostgreSQL as additional database connection to the settings.py:

DATABASES = {
    "default": {
        # Database engine
        "ENGINE": "django.db.backends.mysql",
        # Database name
        "NAME": "weblate",
        # Database user
        "USER": "weblate",
        # Database password
        "PASSWORD": "password",
        # Set to empty string for localhost
        "HOST": "database.example.com",
        # Set to empty string for default
        "PORT": "",
        # Additional database options
        "OPTIONS": {
            # In case of using an older MySQL server, which has MyISAM as a default storage
            # 'init_command': 'SET storage_engine=INNODB',
            # Uncomment for MySQL older than 5.7:
            # 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'",
            # If your server supports it, see the Unicode issues above
            "charset": "utf8mb4",
            # Change connection timeout in case you get MySQL gone away error:
            "connect_timeout": 28800,
        },
    },
    "postgresql": {
        # Database engine
        "ENGINE": "django.db.backends.postgresql",
        # Database name
        "NAME": "weblate",
        # Database user
        "USER": "weblate",
        # Database password
        "PASSWORD": "password",
        # Set to empty string for localhost
        "HOST": "database.example.com",
        # Set to empty string for default
        "PORT": "",
    },
}
  1. Run migrations and drop any data inserted into the tables:

weblate migrate --database=postgresql
weblate sqlflush --database=postgresql | weblate dbshell --database=postgresql
  1. Dump legacy database and import to PostgreSQL

weblate dumpdata --all --output weblate.json
weblate loaddata weblate.json --database=postgresql
  1. Adjust DATABASES to use just PostgreSQL database as default, remove legacy connection.

Weblate should be now ready to run from the PostgreSQL database.

Migrating to PostgreSQL using 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'
    ;
    

Migracja z 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.
