Continues from #3280 in building support for batched requests/responses in the JSON RPC (as per issue #3213).
* Add JSON RPC batching for client and server
As per #3213, this adds support for [JSON RPC batch requests and
responses](https://www.jsonrpc.org/specification#batch).
* Add additional checks to ensure client responses are the same as results
* Fix case where a notification is sent and no response is expected
* Add test to check that JSON RPC notifications in a batch are left out in responses
* Update CHANGELOG_PENDING.md
* Update PR number now that PR has been created
* Make errors start with lowercase letter
* Refactor batch functionality to be standalone
This refactors the batching functionality to rather act in a standalone
way. In light of supporting concurrent goroutines making use of the same
client, it would make sense to have batching functionality where one
could create a batch of requests per goroutine and send that batch
without interfering with a batch from another goroutine.
* Add examples for simple and batch HTTP client usage
* Check errors from writer and remove nolinter directives
* Make error strings start with lowercase letter
* Refactor examples to make them testable
* Use safer deferred shutdown for example Tendermint test node
* Recompose rpcClient interface from pre-existing interface components
* Rename WaitGroup for brevity
* Replace empty ID string with request ID
* Remove extraneous test case
* Convert first letter of errors.Wrap() messages to lowercase
* Remove extraneous function parameter
* Make variable declaration terse
* Reorder WaitGroup.Done call to help prevent race conditions in the face of failure
* Swap mutex to value representation and remove initialization
* Restore empty JSONRPC string ID in response to prevent nil
* Make JSONRPCBufferedRequest private
* Revert PR hard link in CHANGELOG_PENDING
* Add client ID for JSONRPCClient
This adds code to automatically generate a randomized client ID for the
JSONRPCClient, and adds a check of the IDs in the responses (if one was
set in the requests).
* Extract response ID validation into separate function
* Remove extraneous comments
* Reorder fields to indicate clearly which are protected by the mutex
* Refactor for loop to remove indexing
* Restructure and combine loop
* Flatten conditional block for better readability
* Make multi-variable declaration slightly more readable
* Change for loop style
* Compress error check statements
* Make function description more generic to show that we support different protocols
* Preallocate memory for request and result objects
* bound mempool memory usage
Closes#3079
* rename SizeBytes to TxsTotalBytes
and other small fixes after Zarko's review
* rename MaxBytes to MaxTxsTotalBytes
* make ErrMempoolIsFull more informative
* expose mempool's txs_total_bytes via RPC
* test full response
* fixes after Ethan's review
* config: rename mempool.size to mempool.max_txs
https://github.com/tendermint/tendermint/pull/3248#discussion_r254034004
* test more cases
https://github.com/tendermint/tendermint/pull/3248#discussion_r254036532
* simplify test
* Revert "config: rename mempool.size to mempool.max_txs"
This reverts commit 39bfa36961.
* rename count back to n_txs
to make a change non-breaking
* rename max_txs_total_bytes to max_txs_bytes
* format code
* fix TestWALPeriodicSync
The test was sometimes failing due to processFlushTicks being called too
early. The solution is to call wal#Start later in the test.
* Apply suggestions from code review
* Validating that there are txs in the query results before loop throught the array
* Created tests to validate the error has been fixed
* Added comments
* Fixing misspeling
* check if the variable "skipCount" is bigger than zero. If it is not, we set it to 0. If it, we do not do anything.
* using function that validates the skipCount variable
* undo Gopkg.lock changes
Modify lookForHeight to return a height only there's a equal operator.
Previously, it was returning a height even for range conditions: "height
< 10000".
Fixes#2759

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
