Limit size of room storage (files and history) in Matrix server

[MurzNN]

Is there any ways to limit size of disk storage (total files and history size on megabytes, stored in server database) per chat room or per user in Matrix server?

[MurzNN]

And maybe cleanup rules for auto-delete old history records, images and files?

no

but see #890 #1621 #1730 #2260

How can it be, that there is no implementation of this simple and important feature? I looked at #890 #1621 #1730 #2260 and none of those give a solution to it. Is there some script which will delete everything in any channel after like 180 days including all the uploaded media?

No ready script at now, but can be done via getting list of all rooms and cycling run those scripts on each room:

• https://github.com/matrix-org/synapse/blob/master/docs/admin_api/purge_history_api.rst
• purge_history_api.rst: add example script #1034

And if you are unfearful, just delete old large files with

find ~/.synapse/media_store/ -type f -size +5M -mtime +120 -exec rm -iv {} \; # size >5MB, older than 120 days

Or even for a manual clean up, it would be nice to be able to extend the APIs added in #3479 and #8519 to be able to target media by room so popular noisy chat rooms can be manually purged more often than small rooms between close friends.
