Subject: Subversion Ruby Bindings access to URL

So I struggled through the installation of swig, subversion and the
ruby bindings, and now I want to connect to subversion from ruby.

It turns out this is usually done through the filesystem with:

Svn::Repos.open

But, I don't have filesystem access to my repository, I only have web
access

So I need to do something like this:

url = 'http://trac-hacks.swapoff.org/svn'
ctx = Svn::Client::Context.new
cb = Svn::Ra::Callbacks.new(ctx.auth_baton)
cb.auth_baton = Svn::Core.auth_open([])
cfg = Svn::Core::config_get_config(nil)
s = Svn::Ra::Session.open(url, cfg, cb)
st = s.stat(", 1)

(from: http://www.oneofthewolves.com/2007/03/06/ruby-subversion-bindings-finally-some-documentation/#comment-137)

The problem with that one, is that there's no way to pass in my
username and password for htaccess

Looking at the swig and other documentation It seems I need to pass a
C struct struct svn_auth_provider_object_t

To Svn::Core.auth_open([])

And that C struct needs to also contain a function pointer to a
function that then returns username and password somehow?

00149 typedef struct svn_auth_provider_object_t
00150 {
00151   const svn_auth_provider_t *vtable;
00152   void *provider_baton;
00153
00154 } svn_auth_provider_object_t;

http://svn.collab.net/svn-doxygen/group__auth__fns.html


So it seems I need to figure out how to implement a C function pointer
from ruby over swig, I'm guessing this isn't possible....

So, if that's the case I was thinking maybe I could use a Proxy server
to proxy localhost:2901 or some other random port over to my real
repository URL and pass the authentication username and password
through the proxy

Does anybody have any suggestions for such a proxy? perhaps on
implemented in ruby.


And, does anybody have any other suggestions for what I could try to
in order to connect to my remote (And authenticated) repository via
ruby subversion bindings?


thanks,
Jacob
