timeout not respected with socks5 proxy

[a14n]

With httpx[socks]==0.23.3and the following code an httpx.ReadTimeout is raised only with https proxy and not with socks5 proxy. Is it an known issue?

async def main():
   async_client = httpx.AsyncClient(
#        proxies="https://my-https-proxy:443",
       proxies="socks5://my-socks5-proxy:3128",
       follow_redirects=True,
       timeout=1,
   )
   start = time.time_ns()
   try:
       response = await async_client.get(
           "http://www.protesa.net/",
           follow_redirects=False,
       )
       print("status", response.status_code)
   except Exception as e:
       print("ex", type(e))
 #      traceback.print_exc()
   finally:
       print(f"{time.time_ns() - start}ns")
   await async_client.aclose()

if __name__ == '__main__':
   asyncio.run(main())

The output for socks5 proxy is:

ex <class 'socksio.exceptions.ProtocolError'>
59288033291ns

The output for http proxy is:

ex <class 'httpx.ReadTimeout'>
1345715709ns

I have the same issue.
I see httpx passes the timeout to httpcore. And then it's ignored.

So, it’s not a bug in httpx itself, but rather in one of its dependencies:
Issue: encode/httpcore#1015
Fix: encode/httpcore#1017

The fix works, but is not merged yet.

I understand working with a self-patched version is inconvenient, so I can suggest a workaround:

-response = await async_client.get("http://www.protesa.net/", follow_redirects=False)
+response = await asyncio.wait_for(
+    async_client.get("http://www.protesa.net/", follow_redirects=False),
+    timeout=1,
+)

It's not 100% the same, but can be a temporary solution in many cases.
