Peeking over federation via MSC2444 (#1391) * a very very WIP first cut of peeking via MSC2753. doesn't yet compile or work. needs to actually add the peeking block into the sync response. checking in now before it gets any bigger, and to gather any initial feedback on the vague shape of it. * make PeekingDeviceSet private * add server_name param * blind stab at adding a `peek` section to /sync * make it build * make it launch * add peeking to getResponseWithPDUsForCompleteSync * cancel any peeks when we join a room * spell out how to runoutside of docker if you want speed * fix SQL * remove unnecessary txn for SelectPeeks * fix s/join/peek/ cargocult fail * HACK: Track goroutine IDs to determine when we write by the wrong thread To use: set `DENDRITE_TRACE_SQL=1` then grep for `unsafe` * Track partition offsets and only log unsafe for non-selects * Put redactions in the writer goroutine * Update filters on writer goroutine * wrap peek storage in goid hack * use exclusive writer, and MarkPeeksAsOld more efficiently * don't log ascii in binary at sql trace... * strip out empty roomd deltas * re-add txn to SelectPeeks * re-add accidentally deleted field * reject peeks for non-worldreadable rooms * move perform_peek * fix package * correctly refactor perform_peek * WIP of implementing MSC2444 * typo * Revert "Merge branch 'kegan/HACK-goid-sqlite-db-is-locked' into matthew/peeking" This reverts commit 3cebd8dbfbccdf82b7930b7b6eda92095ca6ef41, reversing changes made to ed4b3a58a7855acc43530693cc855b439edf9c7c. * (almost) make it build * clean up bad merge * support SendEventWithState with optional event * fix build & lint * fix build & lint * reinstate federated peeks in the roomserver (doh) * fix sql thinko * todo for authenticating state returned by /peek * support returning current state from QueryStateAndAuthChain * handle SS /peek * reimplement SS /peek to prod the RS to tell the FS about the peek * rename RemotePeeks as OutboundPeeks * rename remote_peeks_table as outbound_peeks_table * add perform_handle_remote_peek.go * flesh out federation doc * add inbound peeks table and hook it up * rename ambiguous RemotePeek as InboundPeek * rename FSAPI's PerformPeek as PerformOutboundPeek * setup inbound peeks db correctly * fix api.SendEventWithState with no event * track latestevent on /peek * go fmt * document the peek send stream race better * fix SendEventWithRewrite not to bail if handed a non-state event * add fixme * switch SS /peek to use SendEventWithRewrite * fix comment * use reverse topo ordering to find latest extrem * support postgres for federated peeking * go fmt * back out bogus go.mod change * Fix performOutboundPeekUsingServer * Fix getAuthChain -> GetAuthChain * Fix build issues * Fix build again * Fix getAuthChain -> GetAuthChain * Don't repeat outbound peeks for the same room ID to the same servers * Fix lint * Don't omitempty to appease sytest Co-authored-by: Kegan Dougal <kegan@matrix.org> Co-authored-by: Neil Alexander <neilalexander@users.noreply.github.com>
