Ethermint currently has to maintain a map height-> block hash on the store (see here) as it needs to expose the eth_getBlockByHash JSON-RPC query for Web3 compatibility. This query is currently not supported by the tendermint RPC client.
## Description
I was able to reproduce this non-determinism locally
After increasing the timeout to 8 seconds from 5 I was not able to reproduce it
Closes: #2856
Mitigates race condition causing these test failures:
```
=== RUN TestTxEventsSentWithBroadcastTxAsync
=== RUN TestTxEventsSentWithBroadcastTxAsync/*http.HTTP
I[2020-05-25|12:29:08.477] Starting WSEvents service impl=WSEvents
TestTxEventsSentWithBroadcastTxAsync/*http.HTTP: event_test.go:124:
Error Trace: event_test.go:124
Error: Expected nil, but got: &errors.errorString{s:"timed out waiting for event"}
Test: TestTxEventsSentWithBroadcastTxAsync/*http.HTTP
Messages: 0: timed out waiting for event
```
Fixes the following test race condition:
```
=== RUN TestAppCalls
TestAppCalls: rpc_test.go:216:
Error Trace: rpc_test.go:216
Error: Expected value not to be nil.
Test: TestAppCalls
--- FAIL: TestAppCalls (2.20s)
```
Closes#4603
Commands used (VIM):
```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```
where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.
Fixes#4802. The Go HTTP server has a global panic handler for requests, so it was not as severe as first thought.
This fix can still panic, since we try to send a `500` response - if that happens, the Go HTTP server will terminate the connection. Otherwise, the client will get a 200 response, which we should avoid. I'm sort of torn on whether it's even necessary to include this fix, instead of just letting the HTTP server deal with it.
Fixes#828. Adds state sync, as outlined in [ADR-053](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-053-state-sync-prototype.md). See related PRs in Cosmos SDK (https://github.com/cosmos/cosmos-sdk/pull/5803) and Gaia (https://github.com/cosmos/gaia/pull/327).
This is split out of the previous PR #4645, and branched off of the ABCI interface in #4704.
* Adds a new P2P reactor which exchanges snapshots with peers, and bootstraps an empty local node from remote snapshots when requested.
* Adds a new configuration section `[statesync]` that enables state sync and configures the light client. Also enables `statesync:info` logging by default.
* Integrates state sync into node startup. Does not support the v2 blockchain reactor, since it needs some reorganization to defer startup.
merged the existing store into pool, consolidated the three buckets into two, used block height as a marked for committed evidence, evidence list recovers on start up, improved error handling
Closes: #4530
This PR contains logic for both submitting an evidence by the light client (lite2 package) and receiving it on the Tendermint side (/broadcast_evidence RPC and/or EvidenceReactor#Receive). Upon receiving the ConflictingHeadersEvidence (introduced by this PR), the Tendermint validates it, then breaks it down into smaller pieces (DuplicateVoteEvidence, LunaticValidatorEvidence, PhantomValidatorEvidence, PotentialAmnesiaEvidence). Afterwards, each piece of evidence is verified against the state of the full node and added to the pool, from which it's reaped upon block creation.
* rpc/client: do not pass height param if height ptr is nil
* rpc/core: validate incoming evidence!
* only accept ConflictingHeadersEvidence if one
of the headers is committed from this full node's perspective
This simplifies the code. Plus, if there are multiple forks, we'll
likely to receive multiple ConflictingHeadersEvidence anyway.
* swap CommitSig with Vote in LunaticValidatorEvidence
Vote is needed to validate signature
* no need to embed client
http is a provider and should not be used as a client
Closes: #4695
Verify /block_results and /validators responses from an HTTP client using the light client.
Added count and total to /validators response.

Add Has function, create better handling of errors when adding evidence, usage of error types.

* fix outliers & undo proto file changes
Using the WebSocket server, when the same client calls multiple time the subscribe method, only the last subscription receives all the events of the previous ones.
example:
subscription1 = tm.event = 'NewBlock'
subscription2 = tm.event = 'Tx'
In this case, subscription2 will receive the new blocks but subscription1 will not.
This came from the WebSocket handler that had the declaration of the rpcrequest moved and so overridden for every request and given in the JSONReq client context (so the id of the subscription was not the right one).
This fixes the issue by simply declaring the rpcrequest inside the loop so every request will create a new object without overwriting the previous one.
