Abstract namespace unix socket

[vetal4444]

Add support for abstruct namespace unix socket. Currently it is raised requests.exceptions.ConnectionError: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory')).

I don't know how to reproduce this. If you can give me a code snippet that reproduces the issue, then I'll consider reopening the issue.

Thanks!

• Create some listen abstract namespace unix socket (for example named test_socket).
  • Try to connect to it.

In [1]: import requests_unixsocket In [2]: session = requests_unixsocket.Session() In [3]: resp = session.get("@test_socket")

MissingSchema: Invalid URL '@test_socket': No schema supplied. Perhaps you meant http://@test_socket?

Ah ok. I wasn't familiar with abstract namespace sockets. Going to reopen so I can investigate this.

Do you have a particular program (Python or otherwise) that creates an abstract namespace socket that you're trying to communicate with?

[msabramo]

I wonder if you tried replacing @ with \0? It seems that's the way to reference abstract domain sockets in C and Python.

You might want to try:

resp = session.get("http+unix://\0test_socket")

Looks like the URL parsing fails:

$ python --version
Python 3.6.9
$ pip show requests-unixsocket | grep Version
Version: 0.1.5
$ python -c "from requests_unixsocket import Session; Session().get('http+unix://\0test_socket')"

During handling of the above exception, another exception occurred:

While curl requests the endpoint just fine:

$ curl --abstract-unix-socket test_socket -i http://127.0.0.1/

I get the same thing. I think it might be due to a change in urllib3.

With a new virtualenv, I get the same error as you, but if I downgrade urllib3:

pip install urllib3==1.20

then that error goes away.
