Nobody said it was reasonable. I didn’t optimize anything, it probably could be slimmed down in some way.
The original software is written to be run on mozillas scale, they only bolted on the selfhosted solution on the side without any documentation. I’m happy that it’s at least working, because I couldn’t install the old version which is written in Python 2.7 on my server anyway anymore.
I have a 6 month old at home so I have half an hour here and there and it took me a couple of weeks to research deep in the comments of the issue tracker and make it work. So once it started working I quickly documented it mostly for my future self and then put it on github just to help others to shorten this research time.
I hope in the future at least the documentation part will be part of the original repo, but I’m not holding my breath that they will optimize anything for selfhosters. Once my son is in kindergarten perhaps I’ll have more time over to look into replacing MariaDB with sqlite and upstream it.
