What is done in this PR:
JSONRPCClient: validate that Response.ID matches Request.ID I wanted
to do the same for the WSClient, but since we're sending events as
responses, not notifications, checking IDs would require storing
them in memory indefinitely (and we won't be able to remove them
upon client unsubscribing because ID is different then).
Request.ID is now optional. Notification is a Request without an ID.
Previously "" or 0 were considered as notifications
Remove #event suffix from ID from an event response (partially fixes
#2949) ID must be either string, int or null AND must be equal to
request's ID. Now, because we've implemented events as responses, WS
clients are tripping when they see Response.ID("0#event") !=
Request.ID("0"). Implementing events as requests would require a lot
of time (~ 2 days to completely rewrite WS client and server)
generate unique ID for each request
switch to integer IDs instead of "json-client-XYZ"
id=0 method=/subscribe
id=0 result=...
id=1 method=/abci_query
id=1 result=...
> send events (resulting from /subscribe) as requests+notifications (not
responses)
this will require a lot of work. probably not worth it

Fixes#4051
Function `parseRemoteAddr` is forcing protocol HTTP and protocol HTTPs to tcp. This causes the bug in the issue #4051.
I find that the tcp is only needed where `net.Dial`. So I moved the switch to makeHTTPDialer.

prometheous change:
due to UninstrumentedHandler, being deprecated in the future
empty branch = empty if or else statement
didn't delete them entirely but commented
couldn't find a reason to have them
could not replicate the issue #3406
but if want to keep it commented then we should comment out the if statement as well
So we can have an error code when rpc fails.
* Update CHANGELOG_PENDING.md
Co-Authored-By: Anton Kaliaev <anton.kalyaev@gmail.com>
* wrap correct error
* format code
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
* Fixed accepting integer IDs in requests for Tendermint RPC server (#2366)
* added a wrapper interface `jsonrpcid` that represents both string and int IDs in JSON-RPC requests/responses + custom JSON unmarshallers
* changed client-side code in RPC that uses it
* added extra tests for integer IDs
* updated CHANGELOG_PENDING, as suggested by PR instructions
* addressed PR comments
* added table driven tests for request type marshalling/unmarshalling
* expanded handler test to check IDs
* changed pending changelog note
* changed json rpc request/response unmarshalling to use empty interfaces and type switches on ID
* some cleanup
* use increment and decrement operators.
* remove unnecessary else branches.
* fix package comment with leading space.
* fix receiver names.
* fix error strings.
* remove omittable code.
* remove redundant return statement.
* Revert changes (code is generated.)
* use cfg as receiver name for all config-related types.
* use lsi as the receiver name for the LastSignedInfo type.
* linter: address gosimple lints
* linter: make deterministic & a rebase fix
* lint/rpc: fix a gosimple lint
* run linter in CI
* fix rebase mistake
* fix makefile
* ugh
* revert Makefile

* need glide
* better
* okayy circle, have it your way
* lints: gosimple

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
* Updated code with feedback from @melekes, @ebuchman and @silasdavis.
* Added Makefile clause `release` to only run the test on seeing tag
`release` during releases i.e
```shell
make release
```
which will run the comprehensive and long integration-ish tests.
Fixes https://github.com/tendermint/tendermint/issues/751.
Adds jitter to our exponential backoff to mitigate a self DDOS
vector. The jitter is a randomly picked percentage of a second
whose purpose is to ensure that each exponential backoff retry
occurs within (1<<attempts) == 2**attempts, but with the delay
each client will have a random buffer time before it tries to
reconnect instead of all at once reconnections that might even
bring back the previous conditions that might have caused the
dial to the WSServer to have failed e.g
* Network outage
* File descriptor exhaustion
* False positives from firewalls
etc
