Subject Re: Error "mod_dav_svn close_stream: error closing write stream" using a write-through proxy

Guten Tag Thorsten Schöning,

close_stream: error closing write stream  [500, #185004]

end of svndiff input  [500, #185004]

Looks like I found my problem and it had nothing to do with the SSH
tunnel: I configured and implemented my own PerlAuthenHandler to be
able to reuse the already existing passwd of my svnserve-repos. For
this to work the handler needs to retrieve the repo name from the URI
of a request. I still use WebSVN and wanted to use the same handler to
restrict access, in the end the only difference is where the repo name
comes from, in case of WebSVN it's a query string parameter. mod_perl
provides anything I need, so I simply used CGI to parse all the
parameters and choosed the one I'm interested in:

> my $request       = $self->_getRequest();
> my $reqArgs       = $request->args();
[...]
> my $retVal = CGI->new($reqArgs)->param('repname');

That's the problem... I don't know what, but CGI didn't just parse
the given parameters and instead did something with the entire request
in a way that svn couldn't read its svndiff data anymore. But only in
the write-through-proxy-scenario, not if I committed locally. After
replacing CGI->new() with some other solution to properly parse the
parameters the commit through the proxy worked. One important part is
to not use some lib again which itself is just a wrapper around using
CGI->new(), CGI::Util::unescape e.g. works.

That was a bad one...

Mit freundlichen Grüßen,

Thorsten Schöning
