Send Application Service Events (#477) * Prevent sql scanning into nil value in accounts_table Signed-off-by: Andrew Morgan <andrewm@matrix.org> * Remove uneccessary logging, null checking * Don't forget to set the localpart * Simplify error checking * Store And Send Application Service Events * Modify INSTALL.md and dendrite-config.yaml for the new appservice database * Correct all instances of casing on 'application service' to align with spec * Store incoming events that an app service is interested in in the database to be later read by transaction workers. * Retrieve these events from transaction workers, one per AS. * Minimal transaction ID data is stored as well to recover after server failure. * Send events to AS and exponentially backoff on failure. Signed-off-by: Andrew Morgan <andrewm@matrix.org> * Finish my own sentences. * Fix up database interaction * Change to event-based AS sending * Reduce cyclomatic complexity * Appease the errcheck gods * Delete by int ID instead of string. This was causing some events to not be deleted, as < an eventID doesn't really make much sense. * Check if there are more events to send before sleeping * Send same transaction if last send attempt failed * Don't backoff on non-200s, tight send loop, 1 event query * Remove tight send loop. Fix events not being deleted * Additionally order by event id, track main.go * Return the last txnID, which our events are using * Remove old main.go file * Prevent duplicate events from being sent... * Strip event content if it doesn't contain anything Signed-off-by: Andrew Morgan <andrewm@matrix.org> * Update gomatrixserverlib and use Unsigned AS event prop * Fixes * Fix sync server comment * Remove unnecessary printlns * Use logrus Fields * Worker state methods * Remove sillyness * Fix up event filtering * Handle transaction event limit in loop * Switch to using a sequence for transaction IDs * Don't verify self-signed AS certificates * Fix logging * Use gmsl.Event instead of AS-only event in transactions Also clear up the logic on lookupStateEvents a little bit. * Change invalid_txn_id to global (for efficiency) * Use a bool for EventsReady instead of an int

Add peer-to-peer support into Dendrite via libp2p and fetch (#880) * Use a fork of pq which supports userCurrent on wasm * Use sqlite3_js driver when running in JS * Add cmd/dendritejs to pull in sqlite3_js driver for wasm only * Update to latest go-sqlite-js version * Replace prometheus with a stub. sigh * Hard-code a config and don't use opentracing * Latest go-sqlite3-js version * Generate a key for now * Listen for fetch traffic rather than HTTP * Latest hacks for js * libp2p support * More libp2p * Fork gjson to allow us to enforce auth checks as before Previously, all events would come down redacted because the hash checks would fail. They would fail because sjson.DeleteBytes didn't remove keys not used for hashing. This didn't work because of a build tag which included a file which no-oped the index returned. See https://github.com/tidwall/gjson/issues/157 When it's resolved, let's go back to mainline. * Use gjson@1.6.0 as it fixes https://github.com/tidwall/gjson/issues/157 * Use latest gomatrixserverlib for sig checks * Fix a bug which could cause exclude_from_sync to not be set Caused when sending events over federation. * Use query variadic to make lookups actually work! * Latest gomatrixserverlib * Add notes on getting p2p up and running Partly so I don't forget myself! * refactor: Move p2p specific stuff to cmd/dendritejs This is important or else the normal build of dendrite will fail because the p2p libraries depend on syscall/js which doesn't work on normal builds. Also, clean up main.go to read a bit better. * Update ho-http-js-libp2p to return errors from RoundTrip * Add an LRU cache around the key DB We actually need this for P2P because otherwise we can *segfault* with things like: "runtime: unexpected return pc for runtime.handleEvent" where the event is a `syscall/js` event, caused by spamming sql.js caused by "Checking event signatures for 14 events of room state" which hammers the key DB repeatedly in quick succession. Using a cache fixes this, though the underlying cause is probably a bug in the version of Go I'm on (1.13.7) * breaking: Add Tracing.Enabled to toggle whether we do opentracing Defaults to false, which is why this is a breaking change. We need this flag because WASM builds cannot do opentracing. * Start adding conditional builds for wasm to handle lib/pq The general idea here is to have the wasm build have a `NewXXXDatabase` that doesn't import any postgres package and hence we never import `lib/pq`, which doesn't work under WASM (undefined `userCurrent`). * Remove lib/pq for wasm for syncapi * Add conditional building to remaining storage APIs * Update build script to set env vars correctly for dendritejs * sqlite bug fixes * Docs * Add a no-op main for dendritejs when not building under wasm * Use the real prometheus, even for WASM Instead, the dendrite-sw.js must mock out `process.pid` and `fs.stat` - which must invoke the callback with an error (e.g `EINVAL`) in order for it to work: ``` global.process = { pid: 1, }; global.fs.stat = function(path, cb) { cb({ code: "EINVAL", }); } ``` * Linting
