Interesting. I'll take a look. I also didn't know curl could work with unix sockets so thanks for showing that!

[jkbrzt]

@msabramo It's actually curl-unix-socket which is a tool written in Go, not curl. Btw, I wonder if it would be possible to adopt this nicer URL syntax.

[jessfraz]

cool! thanks for looking into it.

BTW, I created https://github.com/msabramo/requests-unixsocket (which this is based on) with the thought that perhaps https://github.com/docker/docker-py might be able to use it, so if requests-unixsocket won't work with the docker socket, then I'd like to fix it.

@jfrazelle: I think this is just a simple typo. You did:

http http+unix://%2Fvar%2Frun%sFdocker.sock/info

And I also got an error when I did that. When I replace the %sF with %2F, it works for me.

Does that solve the issue?

This perhaps points out though that perhaps this URL syntax is error-prone and I should look into adopting the nicer URL syntax that curl-unix-socket uses.

[jessfraz]

Wow so sorry!

[msabramo]

@jakubroztocil: It looks like perhaps httpie needs to be modified a bit to support that nicer syntax?

(httpie-unixsocket.venv)vagrant@vagrant-ubuntu-trusty-64:~$ http http+unix:///var/run/docker.sock:/info

http: error: InvalidURL: Invalid URL u'http+unix:///var/run/docker.sock:/info': No host supplied

It's happier with two slashes instead of three (though it still fails because my library doesn't support the new syntax yet):

(httpie-unixsocket.venv)vagrant@vagrant-ubuntu-trusty-64:~$ http http+unix://var/run/docker.sock:/info

http: error: ConnectionError: ('Connection aborted.', error(2, 'No such file or directory'))

[msabramo]

@jfrazelle: No worries. I'm thinking that's a sign that the current syntax is too messy and we should try to have a nicer one like curl-unix-socket does. Interested in helping with that?

[msabramo]

@jakubroztocil: Re my earlier comment; it seems that it's requests that is emitting the No host supplied error:

❯ ag 'No host supplied' requests
requests/requests/models.py
364:            raise InvalidURL("Invalid URL %r: No host supplied" % url)

but maybe there is something that can be done in httpie to avoid hitting that?

[msabramo]

Here's what the stack trace looks like after I commented out the exception handling in httpie:
