When downloading a repository through SVN over HTTP, do it using a proxy if
possible. This is especially useful for people who use Tor to do all their
downloading. This doesn't work with svn:// repositories to my knowledge.
* guix/build/svn.scm (svn-fetch): Pass the "servers:global:http-proxy-host"
and "servers:global:http-proxy-port" configuration options to SVN if
current-http-proxy is set. Bail if unable to parse the proxy to avoid leaks.
* guix/svn-download.scm (svn-fetch): Leak the http_proxy environment variable.

Sorry for the delay, and thanks for the useful patch!
I gather ‘svn’ doesn’t honor ‘http_proxy’ in the first place, right?
That would have simplified things.
Also, what about ‘https_proxy’? (This could be left for a subsequent
patch, if you prefer.)

I would suggest using an explicit (getenv "http_proxy") instead of
(current-http-proxy) since the latter is specific to the (web …)
modules, which are not involved here.
Also, I’m not a fan of SRFI-2. :-) So I’d write it as:
(match (getenv "http_proxy")
(#f '())
(uri-string
(let* ((uri (string->uri uri-string))
(host (uri-host uri))
(port (uri-port uri)))
(list (string-append
"--config-option=servers:global:http-proxy-host="
host)
(string-append
"--config-option=servers:global:http-proxy-port="
(number->string port))))))
Probably with something like:
(unless uri
(format (current-error-port) "invalid HTTP proxy URI: ~s~%"
uri-string)
(exit 1))
Could you send an updated patch?
Thanks!
Ludo’.

No problem. :)

It really would, but for some reason that's not a feature. Well, it was for one
or two releases but that was unintentional and fixed.

I'd have to parse the subversion URL and figure out if its scheme is HTTPS as I
don't think Subverion has a https-proxy-* set of variables.

Sorry for the reply, now that I have an RFC for the coreboot patches I've looked
back at this. The URI module is also in the web module, and I'm not sure how I
feel about rewriting a URI parser to get the host and port out of http_proxy.

Thoughts?

Of course you should keep using ‘string->uri’, no problem with that.
I’m just saying that the code should explicitly check for the
‘http_proxy’ environment variable instead of using the
‘current-http-proxy’ SRFI-9 parameter.
WDYT?

Hi Jookia, Ludo
Was this patch merged? I haven't found it in guix-patches and commits =(. I came across the same problem today by just doing guix pull. In addition, a package (texlive-hyph-utf8) uses svn:// scheme which I am not sure does respect those http-proxy variables.
It would be also nice to have a http/https fallback in svn-download for such cases.
WDYT?

I don't contribute to Guix and abandoned this patch.
Please untag me,

If you can't find it in the commit log, then I doubt the problem was
ever addressed, since SVN and HTTP proxy usage are both somewhat rare.
If you are having this issue, then we need someone to finish the patch,
addressing Ludo's feedback.
