Maintenance tasks

These tasks are available to instance operators:

• rake mastodon:media:clear removes uploads that have not been attached to any status after a while, you would want to run this from a periodic cronjob
• rake mastodon:push:clear unsubscribes from PuSH notifications for remote users that have no local followers. You may not want to actually do that, to keep a fuller footprint of the fediverse or in case your users will soon re-follow
• rake mastodon:push:refresh re-subscribes PuSH for expiring remote users, this should be run periodically from a cronjob and quite often as the expiration time depends on the particular hub of the remote user
• rake mastodon:feeds:clear_all removes all timelines, which forces them to be re-built on the fly next time a user tries to fetch their home/mentions timeline. Only for troubleshooting
• rake mastodon:feeds:clear removes timelines of users who haven't signed in lately, which allows to save RAM and improve message distribution. This is required to be run periodically so that when they login again the regeneration process will trigger

If you receive an error, such as WARNING: Sidekiq testing API enabled, but this is not the test environment. Your jobs will not go to Redis., try adding RAILS_ENV=production to the beginning of each task.
