SVN can't update write-protected files?!?

Hi,

I've just noticed some troublesome behaiour of SVN on Windows: it can't update
write-protected files! This works fine under Linux, though:

-------------- transscript -------------------
joe@joelap:~/tmp$ svnadmin create repo
joe_at_joelap:~/tmp$ svn co file:///home/joe/tmp/repo wc
Checked out revision 0.
joe@joelap:~/tmp$ cd wc
joe@joelap:~/tmp/wc$ touch xx
joe@joelap:~/tmp/wc$ svn add xx
A xx
joe@joelap:~/tmp/wc$ svn -mtest ci
Adding xx
Transmitting file data .
Committed revision 1.
joe@joelap:~/tmp/wc$ echo x>xx
joe@joelap:~/tmp/wc$ svn -mtest ci
Sending xx
Transmitting file data .
Committed revision 2.
joe@joelap:~/tmp/wc$ chmod -r xx
joe@joelap:~/tmp/wc$ svn -r1 up
U xx
Updated to revision 1.
joe@joelap:~/tmp/wc$ svn --version

When I do the same on Windows XP:

-------------- transscript -------------------
C:\tmp>svnadmin create repo
C:\tmp>svn co file:///c:/tmp/repo wc
Checked out revision 0.
C:\tmp>cd wc
C:\tmp\wc>echo x>xx
C:\tmp\wc>svn add xx
A xx
C:\tmp\wc>svn -mtest ci
Adding xx
Transmitting file data .
Committed revision 1.
C:\tmp\wc>echo x>>xx
C:\tmp\wc>svn -mtest ci
Sending xx
Transmitting file data .
Committed revision 2.
C:\tmp\wc>attrib +R xx
C:\tmp\wc>svn -r1 up
U xx
svn: In directory ''
svn: Can't move 'xx.tmp' to 'xx': Zugriff verweigert
C:\tmp\wc>svn --version

Here 'Zugriff verweigert' is german and means 'Access denied'. Why is this
behaviour different? A simple 'attrib -R' on the file cures the problem.

Out tools rely heavily on marking files read-only, and it very time consuming
to check ~15.000 files for read/write flags before any 'svn up', and re-set
the flags afterwards (we don't really want to integrate svn libs into our
tools, we would much prefer to have a 'svn up' always succeed...). Is this a
bug? I would think so, but I did not find any issue for this.

Greetings,
 Joerg
