## 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.
closes: #1859closes: #2905

* Allow testnet hostnames to be overridden
This allows one to specify the `--hostname` flag multiple times, each
time providing an additional custom hostname for a respective peer
(validator or non-validator). This overrides any of the
`--hostname-prefix` or `--starting-ip-address` flags.
The string array approach is taken instead of the string slice approach
(see the pflag docs:
https://godoc.org/github.com/spf13/pflag#StringArray) because the string
slice approach (a comma-separated string) doesn't allow for cleaner
multi-line BASH scripts - where this feature is intended to be used.
* Reorder conditional for clarity with simpler earlier return
* Allow for specifying peer hostname suffix

* Fix command switch
* Add CHANGELOG_PENDING entry for PR
* Allow for unique monikers
The current approach to generating monikers for testnet nodes assigns
the local hostname of the machine on which the testnet config was
generated to all nodes. This results in the same moniker for each and
every node.
This commit makes use of the supplied `--hostname-prefix` and
`--hostname-suffix`, or `--hostname` parameters to generate unique
monikers for each node. Alternatively, another parameter
(`--random-monikers`) allows one to forcibly override all of the other
options with random hexadecimal strings.

* mempool: remove only valid (Code==0) txs on Update
so evil proposers can't drop valid txs in Commit stage.
Also remove invalid (Code!=0) txs from the cache so they can be
resubmitted.
Fixes#3322@rickyyangz:
In the end of commit stage, we will update mempool to remove all the txs
in current block.
// Update mempool.
err = blockExec.mempool.Update(
block.Height,
block.Txs,
TxPreCheck(state),
TxPostCheck(state),
)
Assum an account has 3 transactions in the mempool, the sequences are
100, 101 and 102 separately, So an evil proposal can only package the
101 and 102 transactions into its proposal block, and leave 100 still in
mempool, then the two txs will be removed from all validators' mempool
when commit. So the account lost the two valid txs.
@ebuchman:
In the longer term we may want to do something like #2639 so we can
validate txs before we commit the block. But even in this case we'd only
want to run the equivalent of CheckTx, which means the DeliverTx could
still fail even if the CheckTx passes depending on how the app handles
the ABCI Code semantics. So more work will be required around the ABCI
code. See also #2185

We don't need it actually.
If we are low on addresses for peering, we need to discover more peers. The
previous behavior would query existing peers; however, if an existing peer
does not participate in peer exchange, then our node will not discover more peers.
This change consults both existing peers as well as seeds when there is a deficit
in address book addresses. This allows for discovering peers though existing channels
as well as via seeds if existing peers do not share addresses.
The node.NewNode method is pretty complex at the moment, an in order to address issues like #3156, we need to simplify the interface for partial node instantiation. In some places, we don't need to build up a full node (like in the node.TestCreateProposalBlock test), but the complexity of such partial instantiation needs to be reduced.
This PR aims to eventually make this easier/simpler.
See also this gist https://gist.github.com/thanethomson/56e1640d057a26186e38ad678a1d114c for some background work done when starting to refactor here.

* 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
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.
* check every block appHash
Fixes#3460
Not really needed, but it would detect if the app changed in a way it
shouldn't have.

Continues from #3280 in building support for batched requests/responses in the JSON RPC (as per issue #3213).
* Add JSON RPC batching for client and server
As per #3213, this adds support for [JSON RPC batch requests and
responses](https://www.jsonrpc.org/specification#batch).
* Add additional checks to ensure client responses are the same as results
* Fix case where a notification is sent and no response is expected
* Add test to check that JSON RPC notifications in a batch are left out in responses
* Update CHANGELOG_PENDING.md
* Update PR number now that PR has been created
* Make errors start with lowercase letter
* Refactor batch functionality to be standalone
This refactors the batching functionality to rather act in a standalone
way. In light of supporting concurrent goroutines making use of the same
client, it would make sense to have batching functionality where one
could create a batch of requests per goroutine and send that batch
without interfering with a batch from another goroutine.
* Add examples for simple and batch HTTP client usage
* Check errors from writer and remove nolinter directives
* Make error strings start with lowercase letter
* Refactor examples to make them testable
* Use safer deferred shutdown for example Tendermint test node
* Recompose rpcClient interface from pre-existing interface components
* Rename WaitGroup for brevity
* Replace empty ID string with request ID
* Remove extraneous test case
* Convert first letter of errors.Wrap() messages to lowercase
* Remove extraneous function parameter
* Make variable declaration terse
* Reorder WaitGroup.Done call to help prevent race conditions in the face of failure
* Swap mutex to value representation and remove initialization
* Restore empty JSONRPC string ID in response to prevent nil
* Make JSONRPCBufferedRequest private
* Revert PR hard link in CHANGELOG_PENDING
* Add client ID for JSONRPCClient
This adds code to automatically generate a randomized client ID for the
JSONRPCClient, and adds a check of the IDs in the responses (if one was
set in the requests).
* Extract response ID validation into separate function
* Remove extraneous comments
* Reorder fields to indicate clearly which are protected by the mutex
* Refactor for loop to remove indexing
* Restructure and combine loop
* Flatten conditional block for better readability
* Make multi-variable declaration slightly more readable
* Change for loop style
* Compress error check statements
* Make function description more generic to show that we support different protocols
* Preallocate memory for request and result objects
* use dialPeer function in a seed mode
Fixes#3532
by storing a number of attempts we've tried to connect in-memory and
removing the address from addrbook when number of attempts > 16
What happened:
New code was supposed to fall back to last height changed when/if it
failed to find validators at checkpoint height (to make release
non-breaking).
But because we did not check if validator set is empty, the fall back
logic was never executed => resulting in LoadValidators returning an
empty validator set for cases where `lastStoredHeight` is checkpoint
height (i.e. almost all heights if the application does not change
validator set often).
How it was found:

I think it's nice when the Client interface has all the methods. If someone does not need a particular method/set of methods, she can use individual interfaces (e.g. NetworkClient, MempoolClient) or write her own interface.

Fixes#3458
Closes#1798
This is done by making every mempool tx maintain a list of peers who its received the tx from. Instead of using the 20byte peer ID, it instead uses a local map from peerID to uint16 counter, so every peer adds 2 bytes. (Word aligned to probably make it 8 bytes)
This also required resetting the callback function on every CheckTx. This likely has performance ramifications for instruction caching. The actual setting operation isn't costly with the removal of defers in this PR.
