Version 3.4.16

Released: August 30, 2020

Changes

Documentation

Language chapter of the documentation was expanded to better explain how to add more languages for documents.

File caching

An issue with a missing file closing statement in the file caching app was fixed. This fix makes it now possible to use object storage for the document image cache.

Requirements

The minimum and recommended requirements were update to include GNU Linux distribution, language, and database versions.

Others

  • Fix logging entry for source errors.

Removals

  • None

Upgrading process

  1. Stop supervisord:

    sudo systemctl stop supervisor
    

Upgrading from Mayan EDMS 3.2.x or earlier

  1. Update the Redis configuration:

    Configure Redis to discard data when it runs out of memory, not save its database, and only keep 2 database:

    echo "maxmemory-policy allkeys-lru" | sudo tee -a /etc/redis/redis.conf
    echo "save \"\"" | sudo tee -a /etc/redis/redis.conf
    echo "databases 2" | sudo tee -a /etc/redis/redis.conf
    echo "requirepass mayanredispassword" | sudo tee -a /etc/redis/redis.conf
    sudo systemctl restart redis
    
  2. Install the Python 3 development OS package:

    sudo apt-get install python3-dev
    
  3. Update the virtualenv to use Python 3:

    sudo -u mayan virtualenv --clear /opt/mayan-edms -p /usr/bin/python3
    
  4. Create a home directory for the Mayan EDMS system user:

    mkdir /home/mayan
    
  5. Grant ownership to the Mayan EDMS system user:

    chown mayan:mayan /home/mayan
    
  6. Reinstall the Python client for PostgreSQL and Redis:

    sudo -u mayan /opt/mayan-edms/bin/pip install psycopg2==2.8.4 redis==3.4.1
    

    Note

    Platforms with the ARM CPU might also need additional requirements:

    sudo -u mayan /opt/mayan-edms/bin/pip install psutil==5.7.0
    
  7. Reinstall the Python client for RabbitMQ if you are using RabbitMQ as a broker:

    sudo -u mayan /opt/mayan-edms/bin/pip install amqp==2.5.2
    

Upgrading from Mayan EDMS 3.3.x

  1. Upgrade to the latest pip version:

    sudo -u mayan /opt/mayan-edms/bin/pip install -U pip
    
  2. Update the Redis configuration to enable password protection:

    echo "requirepass mayanredispassword" | sudo tee -a /etc/redis/redis.conf
    sudo systemctl restart redis
    
  3. Remove deprecated requirements:

    sudo -u mayan curl https://gitlab.com/mayan-edms/mayan-edms/raw/master/removals.txt -o /tmp/removals.txt \
    && sudo -u mayan /opt/mayan-edms/bin/pip uninstall -y -r /tmp/removals.txt
    
  4. Update the Mayan EDMS Python package:

    sudo -u mayan /opt/mayan-edms/bin/pip install mayan-edms==3.4.16
    

    the requirements will also be updated automatically.

  5. Make a backup of your supervisord file:

    sudo cp /etc/supervisor/conf.d/mayan.conf /etc/supervisor/conf.d/mayan.conf.bck
    
  6. Update the supervisord configuration file. Replace the environment variables values show here with your respective settings. This step will refresh the supervisord configuration file with the new queues and the latest recommended layout:

    sudo -u mayan MAYAN_DATABASE_ENGINE=django.db.backends.postgresql MAYAN_DATABASE_NAME=mayan \
    MAYAN_DATABASE_PASSWORD=mayanuserpass MAYAN_DATABASE_USER=mayan \
    MAYAN_DATABASE_HOST=127.0.0.1 MAYAN_MEDIA_ROOT=/opt/mayan-edms/media \
    /opt/mayan-edms/bin/mayan-edms.py platformtemplate supervisord | sudo sh -c "cat > /etc/supervisor/conf.d/mayan.conf"
    

    or:

    sudo -u mayan MAYAN_DATABASES=\"{'default':{'ENGINE':'django.db.backends.postgresql','NAME':'mayan','PASSWORD':'mayanuserpass','USER':'mayan','HOST':'127.0.0.1'}}\" \
    MAYAN_MEDIA_ROOT=/opt/mayan-edms/media \
    /opt/mayan-edms/bin/mayan-edms.py platformtemplate supervisord | sudo sh -c "cat > /etc/supervisor/conf.d/mayan.conf"
    
  7. Edit the supervisord configuration file and update any setting specific to your installation:

    sudo vi /etc/supervisor/conf.d/mayan.conf
    
  8. Migrate existing database schema and static media files with:

    sudo -u mayan MAYAN_DATABASE_ENGINE=django.db.backends.postgresql MAYAN_DATABASE_NAME=mayan \
    MAYAN_DATABASE_PASSWORD=mayanuserpass MAYAN_DATABASE_USER=mayan \
    MAYAN_DATABASE_HOST=127.0.0.1 MAYAN_MEDIA_ROOT=/opt/mayan-edms/media \
    /opt/mayan-edms/bin/mayan-edms.py performupgrade
    

    or:

     sudo -u mayan MAYAN_DATABASES="{'default':{'ENGINE':'django.db.backends.postgresql','NAME':'mayan','PASSWORD':'mayanuserpass','USER':'mayan','HOST':'127.0.0.1'}}" \
     MAYAN_MEDIA_ROOT=/opt/mayan-edms/media \
    /opt/mayan-edms/bin/mayan-edms.py performupgrade
    
  9. Start supervisord:

    sudo systemctl start supervisor
    
  10. Clear the browser cache to avoid loading old web assets.

The upgrade procedure is now complete.
