This is useful for custom state sync `StateProvider` implementations that need to build new states for bootstrapping the node. It will also be useful when implementing other mechanisms to bootstrap nodes, e.g. #4642 and #3713.
The event loop uses a `select` on multiple channels. However, reading from a closed channel in Go always yields the channel's zero value. The processor and scheduler close their channels when done, and since these channels are always ready to receive, the event loop keeps spinning on them.
This changes `routine.terminate()` to not close the channel, and also removes `stopDemux` and instead uses `events` channel closure to signal event loop termination.
Fixes#4687.
Fixes#828. Adds state sync, as outlined in [ADR-053](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-053-state-sync-prototype.md). See related PRs in Cosmos SDK (https://github.com/cosmos/cosmos-sdk/pull/5803) and Gaia (https://github.com/cosmos/gaia/pull/327).
This is split out of the previous PR #4645, and branched off of the ABCI interface in #4704.
* Adds a new P2P reactor which exchanges snapshots with peers, and bootstraps an empty local node from remote snapshots when requested.
* Adds a new configuration section `[statesync]` that enables state sync and configures the light client. Also enables `statesync:info` logging by default.
* Integrates state sync into node startup. Does not support the v2 blockchain reactor, since it needs some reorganization to defer startup.
- only run tests when .go, .mod, .sum files have been touched
- only run proto checks when .proto files have been touched

to prevent data races
note: when we check the ConflictingHeadersEvidence, the copy is used.
Closes#4749
Also, iterate over valToLastHeight instead of loading validators. While it might be slower than accessing a single key in goleveldb, the new code is better adapted to ConsensusParams changes.
to prevent malicious nodes from sending us large messages (~21MB, which
is the default `RecvMessageCapacity`)
This allows us to remove unnecessary `maxMsgSize` check in `decodeMsg`. Since each channel has a msg capacity set to `maxMsgSize`, there's no need to check it again in `decodeMsg`.
Closes#1503
Fixes#2593@alexanderbez This is used in a single place in the SDK, how upset are you about removing it?

The checklist and message in the default PR description were sometimes getting
included in commit messages. This change moves that text from the PR description
to a comment from a [Probot tool](https://probot.github.io/apps/auto-comment/).
merged the existing store into pool, consolidated the three buckets into two, used block height as a marked for committed evidence, evidence list recovers on start up, improved error handling
Reduce the number of targets and make the buildsystem more
flexible by parsing the TENDERMINT_BUILD_OPTIONS command
line variable (a-la Debian, inspired by dpkg-buildpackage's
DEB_BUILD_OPTIONS), e.g:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb'
replaces the old:
$ make install_c
Options can be mix&match'd, e.g.:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb race nostrip'
Three options are available:
- nostrip: don't strip debugging symbols nor DWARF tables.
- cleveldb: use cleveldb as db backend instead of goleveldb;
it switches on the CGO_ENABLED Go environment variale.
- race: pass -race to go build and enable data race detection.
This changeset is a port of gaia pull request: cosmos/gaia#363.
Fixes#4739, kind of. See #4740 for the proper fix.

- Move core stateless validation of the Header type to a ValidateBasic method.
- Call header.ValidateBasic during a SignedHeader validation.
- Call header.ValidateBasic during a PhantomValidatorEvidence validation.
- Call header.ValidateBasic during a LunaticValidatorEvidence validation.
lite tests are skipped since the package is deprecated, no need to waste time on it

- regenerate proto using docker image
- on proto breakage a different compiler is used to generate some more helper functions, on master the same one os not used, reverting back to the one used on master to undo further confusion till proto-breakage is merged
