* p2p/conn: fix deadlock in FlushStop/OnStop
* makefile: set_with_deadlock
* close doneSendRoutine at end of sendRoutine
* conn: initialize channs in OnStart
* 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.
* 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.
* remove dependence on ToVote
* update some comments
* fix tests
* fix tests
* fixes from review
* switch from fork (tendermint/btcd) to orig package (btcsuite/btcd); also
- remove obsolete check in test `size != -1` is always true
- WIP as the serialization still needs to be wrapped
* WIP: wrap signature & privkey, pubkey needs to be wrapped as well
* wrap pubkey too
* use "github.com/ethereum/go-ethereum/crypto/secp256k1" if cgo is
available, else use "github.com/btcsuite/btcd/btcec" and take care of
lower-S when verifying
Annoyingly, had to disable pruning when importing
github.com/ethereum/go-ethereum/ :-/
* update comment
* update comment
* emulate signature_nocgo.go for additional benchmarks:
592bf6a59c/crypto/signature_nocgo.go (L60-L76)
* use our format (r || s) in lower-s form when in the non-cgo case
* remove comment about using the C library directly
* vendor github.com/btcsuite/btcd too
* Add test for the !cgo case
* update changelog pending
Closes#3162#3163
Refs #1958, #2091, tendermint/btcd#1
> Implement a check for the blacklisted low order points, ala the X25519 has_small_order() function in libsodium
(#3010 (comment))
resolves first half of #3010
* close peer's connection to avoid fd leak
Fixes#2967
* rename peer#Addr to RemoteAddr
* fix test
* fixes after Ethan's review
* bring back the check
* changelog entry
* write a test for switch#acceptRoutine
* increase timeouts? :(
* remove extra assertNPeersWithTimeout
* simplify test
* assert number of peers (just to be safe)
* Cleanup in OnStop
* run tests with verbose flag on CircleCI
* spawn a reading routine to prevent connection from closing
* get port from the listener
random port is faster, but often results in

* base verifier: bc->bv and check chainid
* improve some comments
* comments in dynamic verifier
* fix comment in doc about BaseVerifier
It requires the validator set to perfectly match.
* failing test for #2862
* move errTooMuchChange to types. fixes#2862
* changelog, comments
* ic -> dv
* update comment, link to issue
* more proposer priority tests
- test that we don't reset to zero when updating / adding
- test that same power validators alternate
* add another test to track / simulate similar behaviour as in #2960
* address some of Chris' review comments
* address some more of Chris' review comments
* temporarily pushing branch with the following changes:
The total power might change if:
- a validator is added
- a validator is removed
- a validator is updated
Decrement the accums (of all validators) directly after any of these events
(by the inverse of the change)
* Fix 2960 by re-normalizing / scaling priorities to be in bounds of total
power, additionally:
- remove heap where it doesn't make sense
- avg. only at the end of IncrementProposerPriority instead of each
iteration
- update (and slightly improve)
TestAveragingInIncrementProposerPriorityWithVotingPower to reflect
above changes

* test proposer frequencies
* return absolute value for diff. keep testing
* use for loop for div
* cleanup, more tests
* spellcheck
* get rid of using floats: manually ceil where necessary
* Remove float, simplify, fix tests to match chris's proof (#3157)
