federation: parallel sending per instance (#4623)
* federation: parallel sending * federation: some comments * lint and set force_write true when a request fails * inbox_urls return vec * split inbox functions into separate file * cleanup * extract sending task code to separate file * move federation concurrent config to config file * off by one issue * improve msg * fix both permanent stopping of federation queues and multiple creation of the same federation queues * fix after merge * lint fix * Update crates/federate/src/send.rs Co-authored-by: dullbananas <dull.bananas0@gmail.com> * comment about reverse ordering * remove crashable, comment * comment * move comment * run federation tests twice * fix test run * prettier * fix config default * upgrade rust to 1.78 to fix diesel cli * fix clippy * delay * add debug to make localhost urls not valid in ap crate, add some debug logs * federation tests: ensure server stop after test and random activity id * ci fix * add test to federate 100 events * fix send 100 test * different data every time so activities are distinguishable * allow out of order receives in test * lint * comment about https://github.com/LemmyNet/lemmy/pull/4623#discussion_r1565437391 * move sender for clarity, add comment * move more things to members * update test todo comment, use same env var as worker test but default to 1 * remove else below continue * some more cleanup * handle todo about smooth exit * add federate inboxes collector tests * lint * actor max length * don't reset fail count if activity skipped * fix some comments * reuse vars * format * Update .woodpecker.yml * fix recheck time * fix inboxes tests under fast mode * format * make i32 and ugly casts * clippy --------- Co-authored-by: dullbananas <dull.bananas0@gmail.com>
