So much has changed since I originally got the RPC tests working many years ago, most notably modern Linux distros don't even have a way to install python2 via packages, you have to install from source. Continuing with python2 does not seem like a good idea, so we begin migrating thigns to Python 3. Currently running ./test.sh will successfully spin up a test chain but then the test suite crashes when attempting to send an RPC request, which looks to be caused by the test suite internals still expecting python2.

AuthServiceProxy has the following improvements over python-jsonrpc's
|
|
ServiceProxy class:
|
|
|
|
- HTTP connections persist for the life of the AuthServiceProxy object
|
|
(if server supports HTTP/1.1)
|
|
- sends protocol 'version', per JSON-RPC 1.1
|
|
- sends proper, incrementing 'id'
|
|
- sends Basic HTTP authentication headers
|
|
- parses all JSON numbers that look like floats as Decimal
|
|
- uses standard Python json lib
|
