DESCRIPTION
|
||
mustool.php can do lots of things on Mastodon Help’s database.
|
||
SYNOPSIS
|
||
mustool.php [options] <action> [parameters] ...
|
||
ACTIONS
|
||
checkspam
|
||
Tries to detect spam instances, i.e. those with the same TLD, same second
|
||
level domain, variable higher domains, both in «Instances» and «Peers»
|
||
tables.
|
||
deleteinstswhere <condition[s]>
|
||
First, return a list of Instances records matching “condition”, then let
|
||
you choose whether you want to delete them and all records referencing them
|
||
in other tables.
|
||
Example: mustool.php deleteinstswhere "IsMastodon!=1"
|
||
revive
|
||
Set a new, succesful check with current time for every instance that
|
||
succesfully responded to last check.
|
||
shuffle
|
||
Randomize instances list (values in «RPos» column).
|
||
updstats
|
||
Update site’s statistics.
|
||
clean
|
||
Delete records older than '.$opts['clean_notifs_before_weeks'].' weeks from «Notifications» table, and for each
|
||
«Instances» record delete all but the most recent '.$opts['clean_keep_checks'].' records from
|
||
«InstChecks» table.
|
||
optimize
|
||
Optimize all the tables in the database.
|
||
OPTIONS
|
||
-h, --help
|
