XML-RPC doesn't support MultiCall

[PrimozGodec]

New API differ from the old API (pypi.python.org/pypi/):

• search method work different e.g. search({'keywords': "orange3 add-on"}) returns empty list because of space
• MultiCall is not supported.

I know that this API is deprecated but would ask if there is an option to make functionalities work same to support old versions of the softwares.

Search issue is likely #3717

MultiCall must not be supported by our RPC implementation, https://github.com/Pylons/pyramid_rpc

@PrimozGodec if you point to https://legacy.pypi.org does that address your needs for the time being, and eventually do you want/expect the new API to support some of the same functionality?

FTR, something like this (untested) in warehouse/legacy/api/xmlrpc/views.py is one way to go to support this:

@xmlrpc_method(method='system.multicall')
def multicall(request):
    args = request.rpc_args
    responses = []
    for arg in args:
        name = arg.get('methodName')
        params = arg.get('params')
        if name == 'system.multicall':
            raise Exception
        if not name:
            raise Exception
        subreq = Request.blank('/RPC2', base_url=request.application_url)
        subreq.method = 'POST'
        subreq.body = xmlrpclib.dumps(arg)
        response = request.invoke_subrequest(subreq, use_tweens=True)
        responses.append(xmlrpclib.loads(response.body))
    return responses
