Support httpx/httpcore

[smcoll]

i'd be interested in seeing support for httpx alongside aiohttp, httplib, and requests. The default transport layer for httpx is httpcore which supports HTTP/2 in addition to HTTP/1.1.

These libraries have async support for asyncio, trio, and curio.

Hi @smcoll Thanks for opening this feature request. I'll put this in our backlog and would work on it as soon as possible. We would highly appreciate if you want to contribute towards the httpx support in the SDK. :)

I would also recommend you to try and open this request on the OpenTelemetry for Python since it already has a wide array of growing instrumentation support and also active contribution from the open source community. We are also actively working to provide X-Ray support for customers using OpenTelemetry Python.

Cool - i added issue open-telemetry/opentelemetry-python-contrib#263

at first I thought aiohttp was needed, but it's actually available via https://github.com/aws/aws-xray-sdk-python#working-with-aiohttp if you see the client portion. Note however that opentracing support in aiohttp is not complete per aio-libs/aiohttp#3084

btw for others that want to enable it globally I'm doing something like this (note untested):

def _wrap_clientsession_init(func, instance, args, kwargs):
    trace_config = aws_xray_trace_config()
    kwargs['trace_configs'] = [trace_config]
    return func(*args, **kwargs)

wrapt.wrap_function_wrapper(aiohttp, "ClientSession.__init__", _wrap_clientsession_init)
