subversion

unable to open an ra_local session to url

unable to open repository ‘file:///d/svn/…’

repository created by cygwin svn.

error from tortoise svn client  on windows.

There are differences in the version Tortoise SVN uses and the one cygwin’s latest svn uses. The differences will not be a problem, if the repository is accessed through webdav, rather than file:///.
