Also wrote a virtual methd 'getStats()' for AbstractConnection which
puts some basic stats into a QVariantMap for the /stats endpoint.
Subclasses can call the base implementation and add their own stats to
the returned map.
Also in this commit: misc refactoring and nits
It works! I still haven't figured out how to provoke the dreaded
"Workdepth exceeded" error .. but we pretty much drop the connection
anyway on anything too unexpected from bitcoind.
When the bitcoind manager class is written it will back off and try
again if too many disconnects happen.
For now though, the code we have is fast and works well against
bitcoind.
This allows it to talk to things like bitcoind. It still wants a tcp
socket as its transport -- but it can at least now be wrapped in HTTP
for bitcoin as well as re-use of the same code for ElectronX style
linefeed based JSON.
Our RPC lib is nowhere near 100% generic and re-usable but it's a good
first step here with this refactor job.
This should hopefully fully complete our implementation to support
JSON-RPC 2.0 without batching. We still are missing batching but at
least now we implement the non-batching portion of the spec more
completely.
