* improve ResetTestRootWithChainID() concurrency safety
Rely on ioutil.TempDir() to create test root directories and ensure
multiple same-chain id test cases can run in parallel.
* Update config/toml.go
Co-Authored-By: alessio <quadrispro@ubuntu.com>
* clean up test directories after completion
Closes: #1034
* Remove redundant EnsureDir call
* s/PanicSafety()/panic()/s
* Put create dir functionality back in ResetTestRootWithChainID
* Place test directories in OS's tempdir
In modern UNIX and UNIX-like systems /tmp is very often
mounted as tmpfs. This might speed test execution a bit.
* Set 0700 to a const
* rootsDirs -> configRootDirs
* Don't double remove directories
* Avoid global variables
* Fix consensus tests
* Reduce defer stack
* Address review comments
* Try to fix tests
* Update CHANGELOG_PENDING.md

* panic if peer has no state
https://github.com/tendermint/tendermint/issues/2721#issuecomment-435347165
It's confusing that sometimes we check if peer has a state, but most of
the times we expect it to be there
1. add79700b5/mempool/reactor.go (L138)
2. add79700b5/rpc/core/consensus.go (L196) (edited)
I will change everything to always assume peer has a state and panic
otherwise
that should help identify issues earlier
* abci/localclient: extend lock on app callback
App callback should be protected by lock as well (note this was already
done for InitChainAsync, why not for others???). Otherwise, when we
execute the block, tx might come in and call the callback in the same
time we're updating it in execBlockOnProxyApp => DATA RACE
Fixes#2721

* consensus: use read lock in Receive#VoteMessage
* use defer to unlock mutex because application might panic
* use defer in every method of the localClient
* add a changelog entry
* drain channels before Unsubscribe(All)
Read 55362ed766/libs/pubsub/pubsub.go (L13)
for the detailed explanation of the issue.
We'll need to fix it someday. Make sure to keep an eye on
https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-033-pubsub.md
* retry instead of panic when peer has no state in reactors other than consensus
in /dump_consensus_state RPC endpoint, skip a peer with no state
* rpc/core/mempool: simplify error messages
* rpc/core/mempool: use time.After instead of timer
also, do not log DeliverTx result (to be consistent with other memthods)
* unlock before calling the callback in reqRes#SetCallback

```
Explanation:
it blocks on an empty clist forever. so unless theres txs coming in,
this go routine will just sit there, holding onto the peer too.
if we're constantly reconnecting to some peer, old instances are not
garbage collected, leading to memory leak.
