There are two common reasons for that: 1. The file is open (under win32) and herefore you can't write it. 2. The permissions are actually wrong.
Both involves obvious solutions, but the second one is typically the result of using different user accounts to access the same working copy. The first one can also be caused by anti-virus software.
Probably the former. I don't have a virus checker installed, but it's likely that my editor had an open handle to this file.

The typical cause is that some (broken) tool modified the content of the .svn dir, like e.g. search'n'replace running amok. Since the files in there have a different ending and are even write-protected, I'm actually willing to write this off to a broken tool.
I have also seen this happen dues to some filesystem-level corruption which made it impossible to access some dir. Running an extensive check/repair fixed that though.
In case it wasn't clear from my message, I executed these commands one after the other. "svn up" with the permission failure. "svn up" immediately thereafter with the corruption. It seems clear to me that the failure of the first command led to the corruption of my subversion repository. There is no filesystem corruption ... just subversion borking itself. And like I said, it's not the first time.
Does this ever happen to anybody else? I get this random corruption of my local subversion repository about once a month.
That's a lot. Up to now, I have still been able to trace all issues to either misuse (by user or tool), misbehaving virus scanner or (as above) filesystem corruption.
No misuse, and no tool other than subversion. FWIW, I'm running subversion via cygwin on vista. Is this just the price of doing business on windows? "Permission denied!" More subversion corruption. Another day lost. -- Eric Niebler Boost Consulting www.boost-consulting.com
