* NC-1880 High TX volume swamps block processing
Move transaction processing into its own thread(s).
Size of txWorkerExecutor thread pool can be independently configured.
* Plumb in three more metrics
* add blockchain_height gauge
* add blockchain_difficulty_total gauge
* add blockchain_announcedBlock_ingest histogram
This involved some deep pluming such that the metrics system needs to be
created in the PantheonCommand, along with trickle down effects into other
consensus engines. This is likely where it should live anyway.
Metrics being captured initially:
Total number of peers ever connected to
Total number of peers disconnected, by disconnect reason and whether the disconnect was initiated locally or remotely.
Current number of peers
Timing for processing JSON-RPC requests, broken down by method name.
Generic JVM and process metrics (memory used, heap size, thread count, time spent in GC, file descriptors opened, CPU time etc).
Upgrade dependency versions
* All version information is merged into one place
* Upgrade most version to their latest non-test version.
* dependencies are now sorted
Two dependencies were not upgraded:
errorprone - There are new checks that require build or source changes.
vertex - The license to eclipse 2.0 which is not in our current approved license list.
The change is trivial but for tracability it should be done alone.
* Remove release/retain requirement from MessageData.
MessageData now wraps a BytesValue rather than a Netty ByteBuf so we no longer need to call release/retain and pass that through to the underlying ByteBuf.
Entirely removed support for a BytesValue wrapping a Netty ByteBuf as it does not provide any way to release the underlying ByteBuf.
* Add BytesValue.copyTo(byte[]) to avoid the need to call getArrayUnsafe() to copy the data.
Some more logging level downgrades.
* At steady state we should get only one info level log per new block
* We don't need to know about peer stuff at info
* Caught up to best peer fires for every block
Update value returned by web3_clientVersion to be ethstats friendly
* Version part starts with a v
* SNAPSHOT builds report 32 bits of the git hash
* OS and architecture are sniffed out and reported
* JVM version and branding are sniffed out and reported
Example values (not all real):
pantheon/v0.9.0-dev-f800a0b1/osx-x86_64/oracle-java-1.8
pantheon/v0.9.0-dev-27960b57/osx-x86_64/zulu-java-11
pantheon/v0.9.0/linux-arm64/openjdk-java-12
Add tests that hit the retry failure case
Move "complete what we just got" semantic into the
DownloadHeaderSequenceTask. Previously it was completing everything
in the chunk it was assigned.
* Make GenesisConfigFile responsible for handling all the content in the genesis config file and rename GenesisConfig to GenesisState as it is now just responsible for creating the initial state at genesis.
* In CliqueProtocolController, pass the network ID to EthProtocolManager instead of the chain ID and use downloader parallelism setting instead of network ID for the number of threads.
As recommended in #231 alter the API so that the
subclasses always return their list from executePeerTask in the
`CompletableFuture` and reset the retry in `#executeTask()` when any
non-empty list is returned.
A more robust fix: be tolerant of partial success. Instead of counting
every call as a limited retry change the semantics of
AbstractRetryingPeerTask such that it's retryCounter may be reset on a
partial success. Hence the limit is on consecutive zero progress
retries and large blocks dribbled in one at a time are not penalized.
Undo temp fix. Restore retries to 3 in a row.
The MiningCoordinator has been split into common, and ethhash
specific funcationality.
This adversely affects the JSON RPC, in that all mining related
RPCs are now generic based on the type of miner being used.
