4d7cd8055b blockchain: Reorg reactor (#3561)
* go routines in blockchain reactor

* Added reference to the go routine diagram

* Initial commit

* cleanup

* Undo testing_logger change, committed by mistake

* Fix the test loggers

* pulled some fsm code into pool.go

* added pool tests

* changes to the design

added block requests under peer

moved the request trigger in the reactor poolRoutine, triggered now by a ticker

in general moved everything required for making block requests smarter in the poolRoutine

added a simple map of heights to keep track of what will need to be requested next

added a few more tests

* send errors to FSM in a different channel than blocks

send errors (RemovePeer) from switch on a different channel than the
one receiving blocks
renamed channels
added more pool tests

* Added timeout on next block needed to advance

* updating docs and cleanup

* fix issue in test from previous cleanup

* cleanup

* Added termination scenarios, tests and more cleanup

* small fixes to adr, comments and cleanup

* Fix bug in sendRequest()

If we tried to send a request to a peer not present in the switch, a
missing continue statement caused the request to be blackholed in a peer
that was removed and never retried.

While this bug was manifesting, the reactor kept asking for other
blocks that would be stored and never consumed. Added the number of
unconsumed blocks in the math for requesting blocks ahead of current
processing height so eventually there will be no more blocks requested
until the already received ones are consumed.

* remove bpPeer's didTimeout field

* Use distinct err codes for peer timeout and FSM timeouts

* Don't allow peers to update with lower height

* review comments from Ethan and Zarko

62f97a69e9 abci: Refactor CheckTx to notify of recheck (#3744)
As per #2127, this refactors the RequestCheckTx ProtoBuf struct to allow for a flag indicating whether a query is a recheck or not (and allows for possible future, more nuanced states).

In order to pass this extended information through to the ABCI app, the proxy.AppConnMempool (and, for consistency, the proxy.AppConnConsensus) interface seems to need to be refactored along with abcicli.Client.

And, as per this comment, I've made the following modification to the protobuf definition for the RequestCheckTx structure:

enum CheckTxType {
  New = 0;
  Recheck = 1;
}

message RequestCheckTx {
  bytes tx = 1;
  CheckTxType type = 2;
}

* Refactor ABCI CheckTx to notify of recheck

As per #2127, this refactors the `RequestCheckTx` ProtoBuf struct to allow for:

1. a flag indicating whether a query is a recheck or not (and allows for
   possible future, more nuanced states)
2. an `additional_data` bytes array to provide information for those more
   nuanced states.

In order to pass this extended information through to the ABCI app, the
`proxy.AppConnMempool` (and, for consistency, the
`proxy.AppConnConsensus`) interface seems to need to be refactored.

Commits:

* Fix linting issue

* Add CHANGELOG_PENDING entry

* Remove extraneous explicit initialization

* Update ABCI spec doc to include new CheckTx params

* Rename method param for consistency

* Rename CheckTxType enum values and remove additional_data param

4905640e9b types: CommitVotes struct as last step towards #1648 (#3298)
* VoteSignBytes builds CanonicalVote

* CommitVotes implements VoteSetReader

- new CommitVotes struct holds both the Commit and the ValidatorSet and
  implements VoteSetReader
- ToVote takes a ValidatorSet

* fix TestCommit

* use CommitSig.BlockID

Commits may include votes for a different BlockID, could be nil,
or different altogether. This means we can't use `commit.BlockID`
for reconstructing the sign bytes, since up to -1/3 of the commits
might be for independent BlockIDs. This means CommitSig will need to
include an indicator for what BlockID it signed - if it's not the
committed one or nil, it will need to include it fully in order to be
verified. This is unfortunate but unavoidable so long as we include
votes for non-committed BlockIDs (which we do to track validator
liveness)

* fixes from review

* remove CommitVotes. CommitSig contains address

* remove commit.canonicalVote method

* toVote -> getVote, takes valIdx

* update adr-025

    Option renamed to CListOption
    MempoolReactor renamed to Reactor

Non Breaking changes in the node package:

[node] #2659 Add Mempool method, which allows you to access mempool

## Commits

* move Mempool interface into mempool package

Refs #2659

Breaking changes in the mempool package:

- Mempool now an interface
- old Mempool renamed to CListMempool

Breaking changes to state package:

- MockMempool moved to mempool/mock package and renamed to Mempool
- Mempool interface moved to mempool package

* assert CListMempool impl Mempool

* gofmt code

* rename MempoolReactor to Reactor

- combine everything into one interface
- rename TxInfo.PeerID to TxInfo.SenderID
- unexpose MempoolReactor.Mempool

* move mempool mock into top-level mock package

* add a fixme

TxsFront should not be a part of the Mempool interface
because it leaks implementation details. Instead, we need to come up
with general interface for querying the mempool so the MempoolReactor
can fetch and broadcast txs to peers.

* change node#Mempool to return interface

* save commit = new reactor arch

* Revert "save commit = new reactor arch"

This reverts commit 1bfceacd9d65a720574683a7f22771e69af9af4d.

* require CListMempool in mempool.Reactor

* add two changelog entries

* fixes after my own review

* quote interfaces, structs and functions

* fixes after Ismail's review

* make node's mempool an interface

* make InitWAL/CloseWAL methods a part of Mempool interface

* fix merge conflicts

* make node's mempool an interface

b738add80c cs: fix nondeterministic tests (#3582)
Should fix #3451, #2723 and #3317.

Test TestResetTimeoutPrecommitUponNewHeight is simplified so it reduces a risk of timeout failure. Furthermore, timeout we wait for TimeoutEvents is increased, and the timeout value is more precisely computed. This should hopefully decrease a chance of non-deterministic test failures.

This assertion is problematic to ensure consistently due to dependency on scheduler. On the other hand, if I am not wrong, order in which messages are read from the channel respects order in which messages are written. Therefore, process will receive 2f+1 precommits that are not all for v (one is for nil) so TriggeredTimeoutPrecommit would be set to true. So we don't need to assert it. I know that it would be better to still assert to it but I don't know how to do it without sleep and that is ugly and is causing us nondeterministic failures.

make ineffassign linter pass (#3386)
Refs #3262

This fixes two small bugs:

1) lite/dbprovider: return `ok` instead of true in parse* functions. It's weird that we're ignoring `ok` value before.
2) consensus/state: previously because of the shadowing we almost never output "Error with msg". Now we declare both `added` and `err` in the beginning of the function, so there's no shadowing.

As per
https://github.com/tendermint/tendermint/pull/3300#discussion_r255886586,
this removes the `testChan` WAL member and replaces the approach with a
system time-oriented one. In this new approach, we keep track of the
system time at which each flush and periodic flush successfully
occurred.

The naming of the various functions is also updated here to be more
consistent with "flushing" as opposed to "sync'ing".

* Update naming convention and ensure lock for timestamp update

* Add Flush method as part of WAL interface

Adds a `Flush` method as part of the WAL interface to enforce the idea
that we can manually trigger a WAL flush from outside of the WAL. This
is employed in the consensus state management to flush the WAL prior to
signing votes/proposals, as per https://github.com/tendermint/tendermint/issues/3043#issuecomment-453853630

* Update CHANGELOG_PENDING

* Remove mutex approach and replace with DI

The dependency injection approach to dealing with testing concerns could
allow similar effects to some kind of "testing bus"-based approach. This
commit introduces an example of this, where instead of relying on
(potentially fragile) timing of things between the code and the test, we
inject code into the function under test that can signal the test
through a channel.

This allows us to avoid the `time.Sleep()`-based approach previously
employed.

* Expand commentary on WAL disk flushing

Co-Authored-By: thanethomson <connect@thanethomson.com>

* Add broken test to illustrate WAL sync test problem

Removes test-related state (dependency injection code) from the WAL data
structure and adds test code to illustrate the problem with using
`WALGenerateNBlocks` and `wal.SearchForEndHeight` to test periodic
sync'ing.

* Fix test error messages

* Use WAL group buffer size to check for flush

A function is added to `libs/autofile/group.go#Group` in order to return
the size of the buffered data (i.e. data that has not yet been flushed
to disk). The test now checks that, prior to a `time.Sleep`, the group
buffer has data in it. After the `time.Sleep` (during which time the
periodic flush should have been called), the buffer should be empty.

* Remove config root dir removal from #3291

* Add godoc for NewWAL mentioning periodic sync

cs/wal: refuse to encode msg that is bigger than maxMsgSizeBytes (#3303)
Earlier this week somebody posted this in GoS Riot chat:

```

```

Note the length error messages. What has happened is the length field got corrupted probably. I've looked at the code and noticed that we don't check the msg size during encoding. This PR fixes that. It also improves a few error messages in WALDecoder.

fix non deterministic test failures and race in privval socket (#3258)
* node: decrease retry conn timeout in test

Should fix #3256

The retry timeout was set to the default, which is the same as the
accept timeout, so it's no wonder this would fail. Here we decrease the
retry timeout so we can try many times before the accept timeout.

* p2p: increase handshake timeout in test

This fails sometimes, presumably because the handshake timeout is so low
(only 50ms). So increase it to 1s. Should fix #3187

* privval: fix race with ping. closes #3237

Pings happen in a go-routine and can happen concurrently with other
messages. Since we use a request/response protocol, we expect to send a
request and get back the corresponding response. But with pings
happening concurrently, this assumption could be violated. We were using
a mutex, but only a RWMutex, where the RLock was being held for sending
messages - this was to allow the underlying connection to be replaced if
it fails. Turns out we actually need to use a full lock (not just a read
lock) to prevent multiple requests from happening concurrently.

* node: fix test name. DelayedStop -> DelayedStart

* autofile: Wait() method

In the TestWALTruncate in consensus/wal_test.go we remove the WAL
directory at the end of the test. However the wal.Stop() does not
properly wait for the autofile group to finish shutting down. Hence it
was possible that the group's go-routine is still running when the
cleanup happens, which causes a panic since the directory disappeared.
Here we add a Wait() method to properly wait until the go-routine exits
so we can safely clean up. This fixes #2852.

Introduce CommitSig alias for Vote in Commit (#3245)
* types: memoize height/round in commit instead of first vote

* types: commit.ValidateBasic in VerifyCommit

* types: new CommitSig alias for Vote

In preparation for reducing the redundancy in Commits, we introduce the
CommitSig as an alias for Vote. This is non-breaking on the protocol,
and minor breaking on the Go API, as Commit now contains a list of
CommitSig instead of Vote.

WAL: better errors and new fail point (#3246)
* privval: more info in errors

* wal: change Debug logs to Info

* wal: log and return error on corrupted wal instead of panicing

* fail: Exit right away instead of sending interupt

* consensus: FAIL before handling our own vote

allows to replicate #3089:
- run using `FAIL_TEST_INDEX=0`
- delete some bytes from the end of the WAL
- start normally

Results in logs like:
