[Posting to Cygwin list. Please keep discussion there.]

I did apply the patch from Fedora, but it didn't seem to help.

I just rebuilt subversion-1.9.1 using a locally-built version of
swig-3.0.7 (distro has 3.0.5) and that seems to solve the problem. I'll
rebuild subversion-1.9.1 and subversion-1.8.14 using swig-3.0.7 and
upload them shortly.

It looks like Fedora has a patch for this. I'll try applying it to
Subversion this weekend and make a new release. I don't use Mercurial,
but hopefully someone can test the new release.

Thanks, Matt, for the useful link.

This is apparently known breakage with libsvn's SWIG bindings related to
new versions of SWIG. We're more or less powerless to do anything about
it. You can tell it's not Mercurial's problem because the error occurs
-in libsvn/core.py- while it's calling SVN.

Problems running "hg convert" with "subversion[-python]" 1.8.13-2

[Dr Rainer Woitok]

Greetings,

having installed  Cygwin's version  1.8.13-2  of both,  "subversion" and
"subversion-python", I get

$ hg convert -d hg -s svn http://gpsbabel.googlecode.com/svn/ gpsbabel

    svn_pool_create()
TypeError: svn_pool_create() takes exactly 2 arguments (0 given)

However, going back to version  1.8.13-1 of both, "subversion" and "sub-
version-python", I get the expected result:

$ hg convert -d hg -s svn http://gpsbabel.googlecode.com/svn/ gpsbabel
initializing destination gpsbabel repository
scanning source...
... and so on ...

Sincerely,
  Rainer

PS: I "Cc:"-ed the Mercurial people because -- even though I'm convinced
this is a Cygwin problem -- I think they should at least know.
