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.

The `NodeInfo` interface does not appear to serve any purpose at all, so I removed it and renamed the `DefaultNodeInfo` struct to `NodeInfo` (including the Protobuf representations). Let me know if this is actually needed for anything.
Only the Protobuf rename is listed in the changelog, since we do not officially support API stability of the `p2p` package (according to `README.md`). The on-wire protocol remains compatible.
Closes#5766
* memoize the scSchedulerFail error to avoid printing it every scheduleFreq
* blockchain/v2: modify switchIO funcs to accept peer instead of peerID
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.)
I introduced a new variable - syncEnded, which is now used to prevent
sending new events to channels (which would block otherwise) if reactor
is finished syncing
Closes#4591
Closes#5444
Now we record the fact that a peer does not have a requested block and later use this information to make a new request for the same block from another peer.
Before: scheduler receives psBlockProcessed event, but does not mark block as processed because peer timed out (or was removed for other reasons) and all associated blocks were rescheduled.
After: scheduler receives psBlockProcessed event and marks block as processed in any case (even if peer who provided this block errors).
Closes#5387
When a peer is stopped due to some network issue, the Reactor calls scheduler#handleRemovePeer, which removes the peer from the scheduler. BUT the peer stays in the processor, which sometimes could lead to "duplicate block enqueued by processor" panic WHEN the same block is requested by the scheduler again from a different peer. The solution is to return scPeerError, which will be propagated to the processor. The processor will clean up the blocks associated with the peer in purgePeer.
Closes#5513, #5517
## Description
Add simple `NoBlockResponse` handling to blockchain reactor v1. I tested before and after with erik's e2e testing and was not able to reproduce the inability to sync after the changes were applied
Closes: #5394
## Description
Check block protocol version in header validate basic.
I tried searching for where we check the P2P protocol version but was unable to find it. When we check compatibility with a node we check we both have the same block protocol and are on the same network, but we do not check if we are on the same P2P protocol. It makes sense if there is a handshake change because we would not be able to establish a secure connection, but a p2p protocol version bump may be because of a p2p message change, which would go unnoticed until that message is sent over the wire. Is this purposeful?
Closes: #4790
## 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?
While working on tendermint my colleague @jinmannwong fixed a few of the unit tests that we found to be flaky in our CI. We thought that you might find this useful, see below for comments.
## 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
- drop Height & Base from StatusRequest
It does not make sense nor it's used anywhere currently. Also, there
seem to be no trace of these fields in the ADR-40 (blockchain reactor
v2).
- change PacketMsg#EOF type from int32 to bool
check bcR.fastSync flag when "OnStop"
fix "service/service.go:161 Not stopping BlockPool -- have not been started yet {"impl": "BlockPool"}" error when kill process
## Description
this PR adds test vectors for proto encoding. the main difference from amino was the removal of four bytes due to interface encoding.
should i add more cases?
Closes: #XXX
## 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
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`.
Integrates the blockchain v2 reactor with state sync, fixes#4765. This mostly involves deferring fast syncing until after state sync completes. I tried a few different approaches, this was the least effort:
* `Reactor.events` is `nil` if no fast sync is in progress, in which case events are not dispatched - most importantly `AddPeer`.
* Accept status messages from unknown peers in the scheduler and register them as ready. On fast sync startup, broadcast status requests to all existing peers.
* When switching from state sync, first send a `bcResetState` message to the processor and scheduler to update their states - most importantly the initial block height.
* When fast sync completes, shut down event loop, scheduler and processor, and set `events` channel to `nil`.
Predominantly following the discussions regarding the conventions of using mocks, I have decided to revert back to the previous state where mocks were specialized and stored in the separate packages that used them rather then have a generalized mock in the evidence package.
This also was a problem as the state package were running tests too slow and occasionally timing out unnecessarily.
For the replay file I renamed mockEvidencePool to emptyEvidencePool to illustrate that it was intentionally like this and not give the impression that testing software was being used in production
Closes: #4786
The event loop uses a `select` on multiple channels. However, reading from a closed channel in Go always yields the channel's zero value. The processor and scheduler close their channels when done, and since these channels are always ready to receive, the event loop keeps spinning on them.
This changes `routine.terminate()` to not close the channel, and also removes `stopDemux` and instead uses `events` channel closure to signal event loop termination.
Fixes#4687.
