new pubsub package comment out failing consensus tests for now rewrite rpc httpclient to use new pubsub package import pubsub as tmpubsub, query as tmquery make event IDs constants EventKey -> EventTypeKey rename EventsPubsub to PubSub mempool does not use pubsub rename eventsSub to pubsub new subscribe API fix channel size issues and consensus tests bugs refactor rpc client add missing discardFromChan method add mutex rename pubsub to eventBus remove IsRunning from WSRPCConnection interface (not needed) add a comment in broadcastNewRoundStepsAndVotes rename registerEventCallbacks to broadcastNewRoundStepsAndVotes See https://dave.cheney.net/2014/03/19/channel-axioms stop eventBuses after reactor tests remove unnecessary Unsubscribe return subscribe helper function move discardFromChan to where it is used subscribe now returns an err this gives us ability to refuse to subscribe if pubsub is at its max capacity. use context for control overflow cache queries handle err when subscribing in replay_test rename testClientID to testSubscriber extract var set channel buffer capacity to 1 in replay_file fix byzantine_test unsubscribe from single event, not all events refactor httpclient to return events to appropriate channels return failing testReplayCrashBeforeWriteVote test fix TestValidatorSetChanges refactor code a bit fix testReplayCrashBeforeWriteVote add comment fix TestValidatorSetChanges fixes from Bucky's review update comment [ci skip] test TxEventBuffer update changelog fix TestValidatorSetChanges (2nd attempt) only do wg.Done when no errors benchmark event bus create pubsub server inside NewEventBus only expose config params (later if needed) set buffer capacity to 0 so we are not testing cache new tx event format: key = "Tx" plus a tag {"tx.hash": XYZ} This should allow to subscribe to all transactions! or a specific one using a query: "tm.events.type = Tx and tx.hash = '013ABF99434...'" use TimeoutCommit instead of afterPublishEventNewBlockTimeout TimeoutCommit is the time a node waits after committing a block, before it goes into the next height. So it will finish everything from the last block, but then wait a bit. The idea is this gives it time to hear more votes from other validators, to strengthen the commit it includes in the next block. But it also gives it time to hear about new transactions. waitForBlockWithUpdatedVals rewrite WAL crash tests Task: test that we can recover from any WAL crash. Solution: the old tests were relying on event hub being run in the same thread (we were injecting the private validator's last signature). when considering a rewrite, we considered two possible solutions: write a "fuzzy" testing system where WAL is crashing upon receiving a new message, or inject failures and trigger them in tests using something like https://github.com/coreos/gofail. remove sleep no cs.Lock around wal.Save test different cases (empty block, non-empty block, ...) comments add comments test 4 cases: empty block, non-empty block, non-empty block with smaller part size, many blocks fixes as per Bucky's last review reset subscriptions on UnsubscribeAll use a simple counter to track message for which we panicked also, set a smaller part size for all test cases

abci: Refactor tagging events using list of lists (#3643) ## PR This PR introduces a fundamental breaking change to the structure of ABCI response and tx tags and the way they're processed. Namely, the SDK can support more complex and aggregated events for distribution and slashing. In addition, block responses can include duplicate keys in events. Implement new Event type. An event has a type and a list of KV pairs (ie. list-of-lists). Typical events may look like: "rewards": [{"amount": "5000uatom", "validator": "...", "recipient": "..."}] "sender": [{"address": "...", "balance": "100uatom"}] The events are indexed by {even.type}.{even.attribute[i].key}/.... In this case a client would subscribe or query for rewards.recipient='...' ABCI response types and related types now include Events []Event instead of Tags []cmn.KVPair. PubSub logic now publishes/matches against map[string][]string instead of map[string]string to support duplicate keys in response events (from #1385). A match is successful if the value is found in the slice of strings. closes: #1859 closes: #2905 ## Commits: * Implement Event ABCI type and updates responses to use events * Update messages_test.go * Update kvstore.go * Update event_bus.go * Update subscription.go * Update pubsub.go * Update kvstore.go * Update query logic to handle slice of strings in events * Update Empty#Matches and unit tests * Update pubsub logic * Update EventBus#Publish * Update kv tx indexer * Update godocs * Update ResultEvent to use slice of strings; update RPC * Update more tests * Update abci.md * Check for key in validateAndStringifyEvents * Fix KV indexer to skip empty keys * Fix linting errors * Update CHANGELOG_PENDING.md * Update docs/spec/abci/abci.md Co-Authored-By: Federico Kunze <31522760+fedekunze@users.noreply.github.com> * Update abci/types/types.proto Co-Authored-By: Ethan Buchman <ethan@coinculture.info> * Update docs/spec/abci/abci.md Co-Authored-By: Ethan Buchman <ethan@coinculture.info> * Update libs/pubsub/query/query.go Co-Authored-By: Ethan Buchman <ethan@coinculture.info> * Update match function to match if ANY value matches * Implement TestSubscribeDuplicateKeys * Update TestMatches to include multi-key test cases * Update events.go * Update Query interface godoc * Update match godoc * Add godoc for matchValue * DRY-up tx indexing * Return error from PublishWithEvents in EventBus#Publish * Update PublishEventNewBlockHeader to return an error * Fix build * Update events doc in ABCI * Update ABCI events godoc * Implement TestEventBusPublishEventTxDuplicateKeys * Update TestSubscribeDuplicateKeys to be table-driven * Remove mod file * Remove markdown from events godoc * Implement TestTxSearchDeprecatedIndexing test

  17. Local is a Client implementation that directly executes the rpc

  19. This implementation is useful for:
  20. * Running tests against a node in-process without the overhead
  21. of going through an http server
  22. * Communication between an ABCI app and Tendermint core when they
  23. are compiled in process.
  24. For real clients, you probably want to use client.HTTP. For more
  25. powerful control during testing, you probably want the "client/mock" package.
  26. You can subscribe for any event published by Tendermint using Subscribe method.
  27. Note delivery is best-effort. If you don't read events fast enough, Tendermint
  28. might cancel the subscription. The client will attempt to resubscribe (you
  29. don't need to do anything). It will keep trying indefinitely with exponential
  30. backoff (10ms -> 20ms -> 40ms) until successful.
