[Pkg-matrix-maintainers] Bug#927057: 1Gb of logs is too much

[Andres Salomon]

I think the issue here is that python's logging isn't compressing older
files.

total 1.1G
-rw-r--r-- 1 matrix-synapse matrix-synapse  68M Apr 22 02:12 homeserver.log
-rw-r--r-- 1 matrix-synapse matrix-synapse 100M Apr 18 05:13 homeserver.log.1
-rw-r--r-- 1 matrix-synapse matrix-synapse 100M Feb 25 13:29 homeserver.log.10
-rw-r--r-- 1 matrix-synapse matrix-synapse 100M Apr 11 19:04 homeserver.log.2

A patch is needed upstream in order to make it compress logs w/ python's
logger:

As a workaround, the package could probably just ship a script in cron.daily
to do the following:

#!/bin/sh -e
for log in /var/log/matrix-synapse/*.log.*[02-9]; do
	test -f $log && gzip $log;
done

After compression, things are a bit more reasonable:
