This cleans synapse's history, automating (and fixing/clarifying) some bits from https://levans.fr/shrink-synapse-database.html.
This does not do anything with the PG database.
- in element - settings, help and about, scroll down to advanced to get your access token
You have three options for storing this, used in this order of precedence:
- hardcoded API key into script
- $XDG_CONFIG_HOME/synapse_apikey
API_KEY=your_access_token
HOMESERVER=https://your.homeserver.url
- as commandline arguments, so:
clean_synapse.sh API_ID=your_access_token HOMESERVER=homeserverurl
If you have busy rooms (such as IRC rooms or RSS feeds) where you want a shorter
history, get their full room ids and save them in a file synapse_busyrooms.ini in
$XDG_CONFIG_HOME, usually $HOME/.config. The format of the file is:
"!firstroom:faithcollapsing.com"
"!secondroom:faithcollapsing.com"
"!thirdroom:libera.chat"
By default, only one day of history is kept in these rooms. That length is configured
in the script at this point (around line 58):
ts=$(( $(date --date="1 days ago" +%s)*1000 ))
All other rooms have one month of history retained. That is configured in the
script at this point (around line 75):
ts=$(( $(date --date="1 month ago" +%s)*1000 ))
#TODO:
- command to just pull full roomlist
- maybe use fzf to select "busy rooms" or rooms to clean on a PRN basis
- select duration for history cleaning at runtime
