Trouble pushing to repository via svn+ssh:// and file://

[Berto]

I've tried to push changes from a bzrsvn repository back into svn without success. I've tried the two methods available in my environment; via file:/// and svn+ssh://. I am pretty sure it's not a permissions issue on the repository because I'm able to interact with it just fine over svn+ssh. I also tried upgrading svn to the trunk, which did not help in this case. I always end up with the error:

SubversionException: ("Can't write to connection: Bad address", 14)

Below is a full trace from ~/.bzr.log:

Thanks!

With the latest revs of software, I no longer get "Can't write to connection [...]", but I still cannot push.

Thanks!

210007 is SVN_ERR_RA_SVN_NO_MECHANISMS

[Jelmer Vernooij (jelmer)]

This basically means that svn was unable to negotiate the authentication credentials. There's not much that can be done about this in bzr-svn, except perhaps a clearer error message.

[Berto (bertosmailbox)]

I would agree with this hypothesis, but I am able to branch the SVN repository just fine. Once I have a repository on my end and make a commit to it I am then unable to push stuff back.

Seeing as I can clone the repository using bzrsvn I don't believe it would be an authentication issue.

[Jelmer Vernooij (jelmer)]

It's quite common for svn repositories to only require authentication on commit, not when branching.

Tim Hatch pointed out this:

[22:48] <jelmer> matid: in other words, configuring with --without-sasl may fix it

from:

http://irclogs.ubuntu.com/2008/04/12/%23bzr.html

and from:

http://www.nabble.com/Crazy-svn%2Bssh-commit-regression-in-trunk-and-1.5-td15349239.html#a15418829

This appears to be svn + SASL issue. I recompiled the trunk version of svn with:

--without-sasl

And things are now working, great!

Attached is a patch to give a description of the error message.

[Jelmer Vernooij (jelmer)]

Any chance you can use the constant rather than the hardcoded error number?

Also, please keep the regular error message intact but only hint the user may have hit this svn bug - it may also be possible that this error happens genuinely.

[Jelmer Vernooij (jelmer)]

Closing bzr-svn portion of this report - this is a bug in SASL or Subversion. At the very least, the error message from Subversion could be clearer.
