## 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

- less detail about internal stuff like the `mempool`
- focus BUG FIX entries more on what was fixed rather than how
* minor cleanup.
- remove entry for GenesisDocProvider, it's being undone
* minor fix
* VoteSignBytes builds CanonicalVote
* CommitVotes implements VoteSetReader
- new CommitVotes struct holds both the Commit and the ValidatorSet and
implements VoteSetReader
- ToVote takes a ValidatorSet
* fix TestCommit
* use CommitSig.BlockID
Commits may include votes for a different BlockID, could be nil,
or different altogether. This means we can't use `commit.BlockID`
for reconstructing the sign bytes, since up to -1/3 of the commits
might be for independent BlockIDs. This means CommitSig will need to
include an indicator for what BlockID it signed - if it's not the
committed one or nil, it will need to include it fully in order to be
verified. This is unfortunate but unavoidable so long as we include
votes for non-committed BlockIDs (which we do to track validator
liveness)
* fixes from review
* remove CommitVotes. CommitSig contains address
* remove commit.canonicalVote method
* toVote -> getVote, takes valIdx
* update adr-025
* commit.ToVoteSet -> CommitToVoteSet
* add test
* fix from review
* 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
See https://github.com/tendermint/tendermint/pull/3403/files#r266208947
In #3403 we unexposed BlockTimeIota from the ABCI, but it's still part
of the ConsensusParams struct, so we have to remember to add it back
after calling PB2TM.ConsensusParams. Instead, PB2TM.ConsensusParams
should take it as an argument
Fixes#3432
* limit number of /subscribe clients and queries per client
Add the following config variables (under [rpc] section):
* max_subscription_clients
* max_subscriptions_per_client
* timeout_broadcast_tx_commit
Fixes#2826
new HTTPClient interface for subscriptions
finalize HTTPClient events interface
remove EventSubscriber
fix data race

Also
- init substructures to avoid panic in pb2tm.ConsensusParams
Before: if csp.Block is nil and we later try to access/write to it,
we'll panic.
After: if csp.Block is nil and we later try to access/write to it,
there'll be no panic.
When scaling and averaging is invoked, it is possible to have validators
with close priorities ending up with same priority. With the current code,
this makes it impossible to verify the priority orders before and after updates.

* WIP: Starts adding remote signer test harness
This commit adds a new command to Tendermint to allow for us to build a
standalone binary to test remote signers such as KMS
(https://github.com/tendermint/kms).
Right now, all it does is test that the local public key matches the
public key reported by the client, and fails at the point where it
attempts to get the client to sign a proposal.
* Fixes typo
* Fixes proposal validation test
This commit fixes the proposal validation test as per #3149. It also
moves the test harness into its own internal package to isolate its
exports from the `privval` package.
* Adds vote signing validation
* Applying recommendations from #3149
* Adds function descriptions for test harness
* Adds ability to ask remote signer to shut down
Prior to this commit, the remote signer needs to manually be shut down,
which is not ideal for automated testing. This commit allows us to send
a poison pill message to the KMS to let it shut down gracefully once
testing is done (whether the tests pass or fail).
* Adds tests for remote signer test harness
This commit makes some minor modifications to a few files to allow for
testing of the remote signer test harness. Two tests are added here:
checking for a fully successful (the ideal) case, and for the case where
the maximum number of retries has been reached when attempting to accept
incoming connections from the remote signer.
* Condenses serialization of proposals and votes using existing Tendermint functions
* Removes now-unnecessary amino import and codec
* Adds error message for vote signing failure
* Adds key extraction command for integration test
Took the code from here:
https://gist.github.com/Liamsi/a80993f24bff574bbfdbbfa9efa84bc7 to
create a simple utility command to extract a key from a local Tendermint
validator for use in KMS integration testing.
* Makes path expansion success non-compulsory
* Fixes segfault on SIGTERM
We need an additional variable to keep track of whether we're
successfully connected, otherwise hitting Ctrl+Break during execution
causes a segmentation fault. This now allows for a clean shutdown.
* Consolidates shutdown checks
* Adds comments indicating codes for easy lookup
* Adds Docker build for remote signer harness
Updates the `DOCKER/build.sh` and `DOCKER/push.sh` files to allow one to
override the image name and Dockerfile using environment variables.
Updates the primary `Makefile` as well as the `DOCKER/Makefile` to allow
for building the `remote_val_harness` Docker image.
* Adds build_remote_val_harness_docker_image to .PHONY
* Removes remote signer poison pill messaging functionality
* Reduces fluff code in command line parsing
As per
https://github.com/tendermint/tendermint/pull/3149#pullrequestreview-196171788,
this reduces the amount of fluff code in the PR down to the bare
minimum.
* Fixes ordering of error check and info log
* Moves remove_val_harness cmd into tools folder
It seems to make sense to rather keep the remote signer test harness in
its own tool folder (now rather named `tm-signer-harness` to keep with
the tool naming convention). It is actually a separate tool, not meant
to be one of the core binaries, but supplementary and supportive.
* Updates documentation for tm-signer-harness
* Refactors flag parsing to be more compact and less redundant
* Adds version sub-command help
* Removes extraneous flags parsing
* Adds CHANGELOG_PENDING entry for tm-signer-harness
* Improves test coverage
Adds a few extra parameters to the `MockPV` type to fake broken vote and
proposal signing. Also adds some more tests for the test harness so as
to increase coverage for failed cases.
* Fixes formatting for CHANGELOG_PENDING.md
* Fix formatting for documentation config
* Point users towards official Tendermint docs for tools documentation
* Point users towards official Tendermint docs for tm-signer-harness
* Remove extraneous constant
* Rename TestHarness.sc to TestHarness.spv for naming consistency
* Refactor to remove redundant goroutine
* Refactor conditional to cleaner switch statement and better error handling for listener protocol
* Remove extraneous goroutine
* Add note about installing tmkms via Cargo
* Fix typo in naming of output signing key

* Replace /home/user with ~/ for brevity
* Fixes "signer.key" typo
* Minor edits for clarification for tm-signer-harness bulid/setup process
* 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.

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

* 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)
