# Note:
# When doing json-rpc requests following `RpcPostError` can occur:
# "Failed to send POST Request with JSON-RPC." when a `HttpClientRequestRef`
# POST request is send in the json-rpc http client.
# This error is raised when the httpclient hits error:
# "Could not send request headers", which in its turn is caused by the
# "Incomplete data sent or received" in `AsyncStream`, which is caused by
# `ECONNRESET` or `EPIPE` error (see `isConnResetError()`) on the TCP stream.
# This can occur when the server side closes the connection, which happens after
# a `httpHeadersTimeout` of default 10 seconds (set on `HttpServerRef.new()`).
# In order to avoid here hitting this timeout a `close()` is done after each
# json-rpc call. Because the first json-rpc call opens up the connection, and it
# remains open until a close() (or timeout). No need to do another connect
# before any new call as the proc `connectToRpcServers` doesn't actually connect
# to servers, as client.connect doesn't do that. It just sets the `httpAddress`.
# Yes, this client json rpc API couldn't be more confusing.
# Could also just retry each call on failure, which would set up a new
# connection.
# We are kind of abusing the unittest2 here to run json rpc tests against other
# processes. Needs to be compiled with `-d:unittest2DisableParamFiltering` or
# the confutils cli will not work.
