[Subclipse-users] Subclipse / JavaSVN bug: updating symlinks that point to directories

I was chided for the temerity of reporting this as a bug without first
getting community approval. While I'm not happy about the attitude (and
having to subscribe to a very-high traffic mailing list just to report a
bug), I'd rather see the problem fixed, so here I am. If someone
concludes that this really is a problem with Subclipse, bug 457 is ready
and waiting to be reopened.

This was with Eclipse 3.1.2, with Subclipse 0.9.105 and Java 1.5.0_03,
on Fedora Core 4 (i386):

I had checked out the trunk of a project (http://trac-hacks.org/svn) and
all went fine. After a day or so, I updated the project. Two
exceptions were thrown complaining about items that were symbolic links
to directories, causing the update to fail. When I removed the symbolic
links in my workspace, and re-ran the update, the update succeeded and
recreated the symbolic link.

The problem occured with the wikigoodiesplugin and pydocplugin projects under
http://trac-hacks.org/svn/.

Mark Phippard suggested that 'subversion only supports symbolic links to files';
I tried the commandline 'svn update' on the same workspace, and it worked
fine with subversion 1.2.3. As I indicated above, Subclipse correctly
checked out these symbolic links to directories the first time; it was
only when it tried to update the links after the initial checkout that
there was a problem.

Mark also suggested that I try switching to JavaHL. As indicated above,
I'm using Fedora Core 4, which only supports Subversion 1.2.3 at this
time, and the Subclipse linkages to JavaHL require Subversion 1.3. I
concluded that I didn't have time to build and debug an RPM for Subversion 1.3.X
for Fedora Core 4.
