The `NodeInfo` interface does not appear to serve any purpose at all, so I removed it and renamed the `DefaultNodeInfo` struct to `NodeInfo` (including the Protobuf representations). Let me know if this is actually needed for anything.
Only the Protobuf rename is listed in the changelog, since we do not officially support API stability of the `p2p` package (according to `README.md`). The on-wire protocol remains compatible.
`abci.Client`:
- Sync and Async methods now accept a context for cancellation
* grpc client uses context to cancel both Sync and Async requests
* local client ignores context parameter
* socket client uses context to cancel Sync requests and to drop Async requests before sending them if context was cancelled prior to that
- Async methods return an error
* socket client returns an error immediately if queue is full for Async requests
* local client always returns nil error
* grpc client returns an error if context was cancelled before we got response or the receiving queue had a space for response (do not confuse with the sending queue from the socket client)
- specify clients semantics in [doc.go](https://raw.githubusercontent.com/tendermint/tendermint/27112fffa62276bc016d56741f686f0f77931748/abci/client/doc.go)
`mempool.TxInfo`
- add optional `Context` to `TxInfo`, which can be used to cancel `CheckTx` request
Closes#5190
* docs: goleveldb is much more stable now
Refs https://github.com/syndtr/goleveldb/issues/226#issuecomment-682495490
* rpc/core/events: make sure WS client receives every event
previously, if the write buffer was full, the response would've been
lost without any trace (log msg, etc.)
* rpc/jsonrpc/server: set defaultWSWriteChanCapacity to 1
Refs #3905Closes#3829
setting write buffer capacity to 1 makes transactions count per block
more stable and also reduces the pauses length by 20s.
before: https://github.com/tendermint/tendermint/issues/3905#issuecomment-681854328 net.Read - 20s
after: net.Read - 0.66s
* rpc/jsonrpc/server: buffer writes and avoid io.ReadAll during read
* config: rename prof_laddr to pprof_laddr and move it to rpc
also, remove `/unsafe_start_cpu_profiler`, `/unsafe_stop_cpu_profiler`
and `/unsafe_write_heap_profile` in favor of pprof server functionality.
Closes#5303
* update changelog
* log start
Adds a genesis parameter `initial_height` which specifies the initial block height, as well as ABCI `RequestInitChain.InitialHeight` to pass it to the ABCI application, and `State.InitialHeight` to keep track of the initial height throughout the code. Fixes#2543, based on [RFC-002](https://github.com/tendermint/spec/pull/119). Spec changes in https://github.com/tendermint/spec/pull/135.
Migrates the `rpc` package to use new JSON encoder in #4955. Branched off of that PR.
Tests pass, but I haven't done any manual testing beyond that. This should be handled as part of broader 0.34 testing.
Closes#4603
Commands used (VIM):
```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```
where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.
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.
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
Closes: #4530
This PR contains logic for both submitting an evidence by the light client (lite2 package) and receiving it on the Tendermint side (/broadcast_evidence RPC and/or EvidenceReactor#Receive). Upon receiving the ConflictingHeadersEvidence (introduced by this PR), the Tendermint validates it, then breaks it down into smaller pieces (DuplicateVoteEvidence, LunaticValidatorEvidence, PhantomValidatorEvidence, PotentialAmnesiaEvidence). Afterwards, each piece of evidence is verified against the state of the full node and added to the pool, from which it's reaped upon block creation.
* rpc/client: do not pass height param if height ptr is nil
* rpc/core: validate incoming evidence!
* only accept ConflictingHeadersEvidence if one
of the headers is committed from this full node's perspective
This simplifies the code. Plus, if there are multiple forks, we'll
likely to receive multiple ConflictingHeadersEvidence anyway.
* swap CommitSig with Vote in LunaticValidatorEvidence
Vote is needed to validate signature
* no need to embed client
http is a provider and should not be used as a client
Closes: #4695
Verify /block_results and /validators responses from an HTTP client using the light client.
Added count and total to /validators response.
