* persistent activity queue * fixes * fixes * make federation workers function callable from outside * log federation instances * dead instance detection not needed here * taplo fmt * split federate bin/lib * minor fix * better logging * log * create struct to hold cancellable task for readability * use boxfuture for readability * reset submodule * fix * fix lint * swap * remove json column, use separate array columns instead * some review comments * make worker a struct for readability * minor readability * add local filter to community follower view * remove separate lemmy_federate entry point * fix remaining duration * address review comments mostly * fix lint * upgrade actitypub-fed to simpler interface * fix sql format * increase delays a bit * fixes after merge * remove selectable * fix instance selectable * add comment * start federation based on latest id at the time * rename federate process args * dead instances in one query * filter follow+report activities by local * remove synchronous federation remove activity sender queue * lint * fix federation tests by waiting for results to change * fix fed test * fix comment report * wait some more * Apply suggestions from code review Co-authored-by: SorteKanin <sortekanin@gmail.com> * fix most remaining tests * wait until private messages * fix community tests * fix community tests * move arg parse * use instance_id instead of domain in federation_queue_state table --------- Co-authored-by: Dessalines <dessalines@users.noreply.github.com> Co-authored-by: SorteKanin <sortekanin@gmail.com>
