Python 3 migration

8.7. Python 3 migration#

Univention Management Console modules and the Python API for them support both Python 2 and Python 3. The code of Univention Management Console modules has to be migrated to Python 3. There is nothing UMC specific regarding the implementation.

To include Python 3 modules for a Univention Management Console Debian package the debian/control has to be adjusted: The Provides entry in package section has to contain ${python3:Provides} for Python 3 and ${python:Provides} for Python 2. Additionally, the Depends entry should contain ${python3:Depends}.

Package: univention-management-console-module-...
Architecture: all
Description: ...

By adjusting the XML definition of the module it can be specified that it is executed with Python 3. The attribute python="3" has to be added to the <module> tag:

<?xml version="1.0" encoding="UTF-8"?>
<umc version="2.0">
    <module id="..." priority="50" version="1.0" python="3">
