## PR
This PR introduces a fundamental breaking change to the structure of ABCI response and tx tags and the way they're processed. Namely, the SDK can support more complex and aggregated events for distribution and slashing. In addition, block responses can include duplicate keys in events.
Implement new Event type. An event has a type and a list of KV pairs (ie. list-of-lists). Typical events may look like:
"rewards": [{"amount": "5000uatom", "validator": "...", "recipient": "..."}]
"sender": [{"address": "...", "balance": "100uatom"}]
The events are indexed by {even.type}.{even.attribute[i].key}/.... In this case a client would subscribe or query for rewards.recipient='...'
ABCI response types and related types now include Events []Event instead of Tags []cmn.KVPair.
PubSub logic now publishes/matches against map[string][]string instead of map[string]string to support duplicate keys in response events (from #1385). A match is successful if the value is found in the slice of strings.

Description:
add boltdb implement for db interface.
The boltdb is safe and high performence embedded KV database. It is based on B+tree and Mmap.
Now it is maintained by etcd-io org. https://github.com/etcd-io/bbolt
It is much better than LSM tree (levelDB) when RANDOM and SCAN read.

* Remove deprecated PanicXXX functions from codebase
As per discussion over
[here](https://github.com/tendermint/tendermint/pull/3456#discussion_r278423492),
we need to remove these `PanicXXX` functions and eliminate our
dependence on them. In this PR, each and every `PanicXXX` function call
is replaced with a simple `panic` call.
* add a changelog entry
Fixes#3457
The topic of the issue is that : write a BlockRequest int requestsCh channel will create an timer at the same time that stop the peer 15s later if no block have been received . But pop a BlockRequest from requestsCh and send it out may delay more than 15s later. So that the peer will be stopped for error("send nothing to us").
Extracting requestsCh into its own goroutine can make sure that every BlockRequest been handled timely.
Instead of the requestsCh handling, we should probably pull the didProcessCh handling in a separate go routine since this is the one "starving" the other channel handlers. I believe the way it is right now, we still have issues with high delays in errorsCh handling that might cause sending requests to invalid/ disconnected peers.

As per #3043, this adds a ticker to sync the WAL every 2s while the WAL is running.

This adds a ticker that flushes the WAL every 2s while the WAL is

* Fix spelling

* 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.

* 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
* 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
* 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.
