[pkg] Use sections from requires.txt to populate Recommends and Suggests As Denis Laxalde pointed out, dh_python can also generate Recommends and Suggests from Python package names. So let's use that instead of manually populating these fields in `debian/control`. Optional dependencies are currently specified in `setup.py` grouped by feature. These dependency groups are turned into sections in `requires.txt`. Thankfully `dh_python3` has options to populate Recommends or Suggests with all package from a given section. `debian/rules` now contains a list of which sections should go to Recommends and which section should go to Suggests. Because such extra list easily gets out-of-sync, we add a third list for ignored sections, and ensure that all sections currently in `requires.txt` get a mentioned in `debian/rules`. Here are the results compared to the previous version with explicit Recommends and Suggests (only listing Python packages): |==============================================================| | only in previous | common | only in new | |==============================================================| | Recommends | |--------------------------------------------------------------| | | python3-docutils | | | python3-fyzz | | | | python3-imaging | | | | | python3-pycryptodome | | | | python3-pyramid | | | | python3-pyramid-multiauth | | | python3-pysqlite2 | | | | | python3-rdflib | | | | python3-repoze.lru | | | python3-simpletal | | | | | python3-vobject | | | | python3-waitress | | | python3-werkzeug | | | | | python3-wsgicors | | |--------------------------------------------------------------| | Suggests | |--------------------------------------------------------------| | | | python3-pil | We also lose versioned dependencies which should not really be an issue for Recommends and Suggests.
