Using socks proxy with git for http(s) transport

Hi all,

i have a socks proxy to access internet.
I successed in configuring git (with GIT_PROXY_COMMAND) to use the
socks proxy for GIT transport protocol.
But how to use this socks proxy with git for HTTP(S) transport protocol ?

Best Regards,
Yves

Try:

  git config --global http.proxy 'socks://yourhost:port'

That will enable it for all git repositories on your machine. Git should
also respect any environment variables that curl handles (because we use
libcurl under the hood), if you prefer to set it up that way. See "man
curl" for details.

Thanks Jeff but it's not working.
I use git 1.8.15
My socks proxy listen on my localhost at port 1080 so I do:
git config --global http.proxy  'socks://127.0.0.1:1080'

But when i try to talk with a git server with http protocol i have:

GIT_TRACE=1 GIT_CURL_VERBOSE=1 git ls-remote

As you can see git connect to my socks proxy (Connected to 127.0.0.1
(127.0.0.1) port 1080) but seems to send the http request directly
instead of a socks command. So it does'nt work :(

Also try setting ALL_PROXY environment variable that curl handle:
export ALL_PROXY='socks5://127.0.0.1:1080'

Work with curl:
curl -v http://git.kernel.org/pub/scm/git/git.git/info/refs?service=git-upload-pack

Hmm. I just double-checked, and it works for me.

I use git 1.8.15

I assume you mean 1.8.1.5 here.

My socks proxy listen on my localhost at port 1080 so I do:
git config --global http.proxy  'socks://127.0.0.1:1080'

That looks right to me.

But when i try to talk with a git server with http protocol i have:
[...]
* About to connect() to proxy 127.0.0.1 port 1080
*   Trying 127.0.0.1... * connected

quoted

[...]

If I set up a simple socks proxy with ssh, like:

  ssh -v -D 1080 my-ssh-host

and run the same command, I get:

  * About to connect() to proxy localhost port 1080 (#0)
  *   Trying 127.0.0.1...
  * SOCKS4 request granted.
  * Connected to localhost (127.0.0.1) port 1080 (#0)
  > GET /pub/scm/git/git.git/info/refs?service=git-upload-pack HTTP/1.1
  [...]
  < HTTP/1.1 200 OK

and it works. It does look like curl is treating localhost:1080 as a
regular http proxy. What version of libcurl do you have? Is there
anything in your environment that might be causing it to override the
configured proxy setting (e.g., an http_proxy or https_proxy environment
variable)?

As you can see git connect to my socks proxy (Connected to 127.0.0.1
(127.0.0.1) port 1080) but seems to send the http request directly

Yeah, that definitely looks like the problem.

You have a (#0) in the log that i have when using curl directly with
the socks proxy

and it works. It does look like curl is treating localhost:1080 as a
regular http proxy. What version of libcurl do you have? Is there
anything in your environment that might be causing it to override the
configured proxy setting (e.g., an http_proxy or https_proxy environment
variable)?

I have try with an old version of curl: 7.15.5 and with the latest in
development curl 7.29.1-DEV.
But it seem that git-remote-http is compile with the old one.

I have no http/proxy environment variables

libcurl 7.15.5 is over 6 years old.

The support for "socks[*]://" prefixes in proxy names was added to libcurl 
7.21.7 (June 23 2011).
