Hm. Sometimes you need different proxies to get to different servers. 
Using an env var would be bad in such (probably rare) cases.

Of course not. There will be a global /etc/svn.conf file, and a ~/.svnrc 
file, where this option can be defaulted. In the meantime, shell aliases 
(perhaps in global config files) are a good alternative.


Relying on environment variables creates a maintenance nightmare, 
especially since not all variables are "standard" on all systems. We 
can't avoid honoring truly standard variables like LANG and LC_* 
(although we do our best with --locale), but IMO should avoid others. 
Putting options in a .rc file at least doesn't pollute the env space for 
other apps.

Then again, maybe I'm paranoid.

Http proxy patch [Was: Re: blah... blah...

[Dale Thatcher <su...@dalethatcher.com>]

Here are the changes I propose to make:

1) Add a proxy callback that will be called with the repos URL.  It returns a
proxy host and port or null.  This would allow clients to make more
complicated decisions on which proxy to use.  Therefore allowing them to
behave in the same way as web browsers with a proxy for most and a list of
exceptions.  The client would be responsible for choosing the appropriate
proxy for each situation.

2) Make a default callback that returns NULL.

3) Add callbacks for proxy username and password.

Comments?

thanks,

- Dale Thatcher
