svn export URL of a file with svn:special fails on Microsoft Windows

[Mark Irving <ir...@home.cam.net.uk>]

[This is intended as a bug report...]

In my repository, I have one file which is a symbolic link used only in 
builds for other machines. It is, of course, checked out with the rest 
when I use svn commands on Microsoft Windows, but appears as a normal 
file.

The svn export command fails when it gets to this file, with message 
"E720032: Can't remove file 'svn-<RANDOM>': The process cannot access 
the file because it is being used by another process." If I use "svn 
export PATH1 PATH2" to do the export from a working copy, the file is 
copied without any error message.

I expect svn export to work (and produce a small plain file on Windows) 
for files with the svn:special property.

Here's what my file looks like.

  svn cat svn://localhost/repos/trunk/Current
  link A
  svn proplist svn://localhost/repos/trunk/Current
  Properties on 'svn://localhost/repos/trunk/Current':
    svn:special

Here is what happens when any "svn export URL PATH" command reaches it. 
There is a pause of a few seconds, then the message.

  svn export svn://localhost/repos/trunk/Current Current
  svn: E720032: Can't remove file 'svn-DBFBE990': The process cannot 
access the file because it is being used by another process.

Possible workrounds for this bug: (a) use svn checkout, or (b) use svn 
export from a working copy.

  svn --version
