"The largest power of two less than the number of items" is actually correct!
For n > 1, let k be the largest power of two smaller than n (i.e.,
k < n <= 2k).

Before we're using it to get a round state in tests. Now it can be done
by calling csX.GetRoundState. We will need to rewrite
TestStateSlashingPrevotes and TestStateSlashingPrecommits, which are
commented right now, to not rely on EventDataRoundState#RoundState
field.

1."abci_query": rpcserver.NewRPCFunc(c.ABCIQuery, "path,data,prove")
"validators": rpcserver.NewRPCFunc(c.Validators, "height"),

When remove peer, block pool simple remove bpPeer,
but do not stop timer, that cause stopError for recorrected

This issue is related to #3107
This is a first renaming/refactoring step before reworking and removing heartbeats.
As discussed with @Liamsi , we preferred to go for a couple of independent and separate PRs to simplify review work.
The changes:
Help to clarify the relation between the validator and remote signer endpoints
Differentiate between timeouts and deadlines
Prepare to encapsulate networking related code behind RemoteSigner in the next PR
My intention is to separate and encapsulate the "network related" code from the actual signer.
SignerRemote ---(uses/contains)--> SignerValidatorEndpoint <--(connects to)--> SignerServiceEndpoint ---> SignerService (future.. not here yet but would like to decouple too)
All reconnection/heartbeat/whatever code goes in the endpoints. Signer[Remote/Service] do not need to know about that.
I agree Endpoint may not be the perfect name. I tried to find something "Go-ish" enough. It is a common name in go-kit, kubernetes, etc.
Right now:
SignerValidatorEndpoint:
handles the listener
contains SignerRemote
Implements the PrivValidator interface
connects and sets a connection object in a contained SignerRemote
delegates PrivValidator some calls to SignerRemote which in turn uses the conn object that was set externally
SignerRemote:
Implements the PrivValidator interface
read/writes from a connection object directly
handles heartbeats
SignerServiceEndpoint:
Does most things in a single place
delegates to a PrivValidator IIRC.

As per #3043, this adds a ticker to sync the WAL every 2s while the WAL is running.
* Flush WAL every 2s
This adds a ticker that flushes the WAL every 2s while the WAL is
running. This is related to #3043.
* Fix spelling
* Increase timeout to 2mins for slower build environments
* Make WAL sync interval configurable
* Add TODO to replace testChan with more comprehensive testBus
* Remove extraneous debug statement
* Remove testChan in favour of using system time
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.

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

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.
* rpc/net_info: change RemoteIP type from net.IP to String
Before:
"AAAAAAAAAAAAAP//rB8ktw=="
which is amino-encoded net.IP byte slice
After:
"192.0.2.1"
Fixes#3251
* rpc/net_info: non-empty response in docs
* not related to linter: remove obsolete constants:
- `Insecure` and `Secure` and type `Security` are not used anywhere
* not related to linter: update example
- NewInsecure was deleted; change example to NewRemoteDB
* address: Binds to all network interfaces (gosec):
- bind to localhost instead of 0.0.0.0
- regenerate test key and cert for this purpose (was valid for ::) and
otherwise we would see:
transport: authentication handshake failed: x509: certificate is
valid for ::, not 127.0.0.1\"
(used https://github.com/google/keytransparency/blob/master/scripts/gen_server_keys.sh
to regenerate certs)
* use sha256 in tests instead of md5; time difference is negligible
* nolint usage of math/rand in test and add comment on its import
- crypto/rand is slower and we do not need sth more secure in tests
* enable linter in circle-ci
* another nolint math/rand in test
* replace another occurrence of md5
* consistent comment about importing math/rand
* types.NewCommit
* use types.NewCommit everywhere
* fix log in unsafe_reset
* memoize height and round in constructor
* notes about deprecating toVote
