* 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.
* [MINOR] no fixed ports in tests
First enable "0" port in PeerDiscoveryAgent so it binds to
an open port. Then change the test to use two PeerDiscoveryAgents
The change to zero is accomplished by populating the endpoint with
the actual bound socket instead of the value passed in. If it is
zero the value will change otherwise it will be the value passed in.
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).
* Add the ipV6 flag to the datagram socket options, this creates a socket that handles both
ipv4 and ipv6 socket connections.
* Set the IPv6 flag state based on the presence or absence of an IPv6 address.
i.e. if your machine runs IPv6 it will accept IPv6 bootnodes and peers. However link-local IPv6 is not fully supported (see issue #288).
* 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.
* Ban Peers via CLI
As part of working on #251 I needed to be able to ban certain nodes from my
connection pool and let others connect. This is a general solution to add
a --banned-nodeids CLI flag where the nodeIds of banned nodes are listed.
We can write directly to the target instead and avoid the caller needing to release the buffer.
Fixes memory leak when clients are repeatedly connecting and disconnecting.
* NC-1026 Make Framer#frame Throw on Excessively Large messages
Note that this is
* NC-1026 Make Framer#frame Throw on Excessively Large messages
It is impossible to receive an uncompressed message < 16MiB because the length field in the header is 3 bytes. So this test will never pass.
* NC-1026 Make Framer#frame Throw on Excessively Large messages
review changes
* NC-1026 Make Framer#frame Throw on Excessively Large messages
Missed change in exception type. Added Null uncompressedLength test.
