Conflicting votes are now sent to the evidence pool to form duplicate vote evidence only once
the height of the evidence is finished and the time of the block finalised.
blockchain/vX reactor priority was decreased because during the normal operation
(i.e. when the node is not fast syncing) blockchain priority can't be
the same as consensus reactor priority. Otherwise, it's theoretically possible to
slow down consensus by constantly requesting blocks from the node.
NOTE: ideally blockchain/vX reactor priority would be dynamic. e.g. when
the node is fast syncing, the priority is 10 (max), but when it's done
fast syncing - the priority gets decreased to 5 (only to serve blocks
for other nodes). But it's not possible now, therefore I decided to
focus on the normal operation (priority = 5).
evidence and consensus critical messages are more important than
the mempool ones, hence priorities are bumped by 1 (from 5 to 6).
statesync reactor priority was changed from 1 to 5 to be the same as
blockchain/vX priority.

After a reactor has failed to parse an incoming message, it shouldn't output the "bad" data into the logs, as that data is unfiltered and could have anything in it. (We also don't think this information is helpful to have in the logs anyways.)
This fixes spurious `TestByzantinePrevoteEquivocation` failures by extending the block range and time spent waiting for evidence. I've seen many runs where the evidence isn't committed until e.g. height 27. Haven't looked into _why_ this happens, but as long as the evidence is committed eventually and the test doesn't spuriously fail I'm (mostly) happy. WDYT @cmwaters?
## Description
Part of the issue is to add metrics to the websocket connection. It seems this would require some moving around of things in the node pkg. I opted to not make this change now, and wait for when we do a node pkg refactor.
If someone disagrees with this appraoch please let me know, I can attempt to get metrics into the rpc layer.
There is not a need to update documentation as it already states this metric is a histogram..
Closes: #1791
## Description
Add missing metrics.
`Blockchain/v2` exposes metrics for events. I don't find these as something a node operator should utilize as it does not bring insight.
Closes: #XXX
## Description
This PR aims to make the crypto.PubKey interface more intuitive.
Changes:
- `VerfiyBytes` -> `VerifySignature`
Before `Bytes()` was amino encoded, now since it is the byte representation should we get rid of it entirely?
EDIT: decided to keep `Bytes()` as it is useful if you are using the interface instead of the concrete key
Closes: #XXX
Followup from #5227. Instead of checking `ResponseInitChain.app_hash` against the genesis doc app hash, we instead replace it. We should probably remove the genesis doc app hash completely, and rely solely on the one from `InitChain`, I'll open a separate issue to discuss this.
Adds a genesis parameter `initial_height` which specifies the initial block height, as well as ABCI `RequestInitChain.InitialHeight` to pass it to the ABCI application, and `State.InitialHeight` to keep track of the initial height throughout the code. Fixes#2543, based on [RFC-002](https://github.com/tendermint/spec/pull/119). Spec changes in https://github.com/tendermint/spec/pull/135.
## Description
Add test vectors for all reactors
- [x] state-sync
- [x] privval
- [x] mempool
- [x] p2p
- [x] evidence
- [ ] light?
this PR is primarily oriented at testvectors for things going over the wire. should we expand the testvectors into types as well?
Closes: #XXX
Fixes#5192.
@liamsi Can you verify that the test vectors match the Rust implementation? I updated `ProofsFromByteSlices()` as well, anything else that should be updated?
Solves #5138 in the way that if a validatorSet is nil or empty it will not try to transform it to protobug

## Description
This PR wraps the stdlib sync.(RW)Mutex & godeadlock.(RW)Mutex. This enables using go-deadlock via a build flag instead of using sed to replace sync with godeadlock in all files
Closes: #3242
Closes#5074
Old code does not work when --consensus.create_empty_blocks=false
(because it only calls tmos.Kill when ApplyBlock fails). New code is
listening ABCI clients for Quit and kills TM process if there were any
errors.
Closes#4926
The dump consensus state had this:
"last_commit": {
"votes": [
"Vote{0:04CBBF43CA3E 385085/00/2(Precommit) 1B73DA9FC4C8 42C97B86D89D @ 2020-05-27T06:46:51.042392895Z}",
"Vote{1:055799E028FA 385085/00/2(Precommit) 652B08AD61EA 0D507D7FA3AB @ 2020-06-28T04:57:29.20793209Z}",
"Vote{2:056024CFA910 385085/00/2(Precommit) 652B08AD61EA C8E95532A4C3 @ 2020-06-28T04:57:29.452696998Z}",
"Vote{3:0741C95814DA 385085/00/2(Precommit) 652B08AD61EA 36D567615F7C @ 2020-06-28T04:57:29.279788593Z}",
Note there's a precommit in there from the first val from May (2020-05-27) while the rest are from today (2020-06-28). It suggests there's a validator from an old instance of the network at this height (they're using the same chain-id!). Obviously a single bad validator shouldn't be an issue. But the Commit refactor work introduced a bug.
When we propose a block, we get the block.LastCommit by calling MakeCommit on the set of precommits we saw for the last height. This set may include precommits for a different block, and hence the block.LastCommit we propose may include precommits that aren't actually for the last block (but of course +2/3 will be). Before v0.33, we just skipped over these precommits during verification. But in v0.33, we expect all signatures for a blockID to be for the same block ID! Thus we end up proposing a block that we can't verify.
## Description
partially cleanup in preparation for errcheck
i ignored a bunch of defer errors in tests but with the update to go 1.14 we can use `t.Cleanup(func() { if err := <>; err != nil {..}}` to cover those errors, I will do this in pr number two of enabling errcheck.
ref #5059
fix bug so that PotentialAmnesiaEvidence is being gossiped
handle inbound amnesia evidence correctly
add method to check if potential amnesia evidence is on trial
fix a bug with the height when we upgrade to amnesia evidence
change evidence to using just pointers.
More logging in the evidence module

* test-vectors for backwards compatibility:
- copy & paste test-vectors from v0.33.5 to ensure
backwards compatibility for vote's SignBytes
* WIP: everything besides time seems to match :-/
* almost
* Found the culprit: field nums weren't consecutive ints ...
* fix order of partset header too
* this last votes-related test can easily be fixed
* some minor changes and fix last failing test
* move proto types back to stdtime, fix various linting
* use libs/protoio
* remvoe commented code
* add comments
* fix tests
* uncomment testscases
* dont ignore error panic
* fix signable test
* fix happy path testing
* fix comment
