I got this error today with Darcs 1.0.4:      
     
darcs failed:  user error (Error applying patch to working dir:    
createDirectory: already exists (File exists))    
This may have left your working directory an inconsistent    
but recoverable state. If you had no un-recorded changes    
by using 'darcs revert' you should be able to make your    
working directory consistent again.

I understand why it's happening--- I already had a local directory that a patch   
added.   
  
It would be ideal to proceed despite this, since it's not really a problem from 
my perspective.  
 
However, as long as there is an error, it should let me know /which/ directory 
has the problem, since there may be several potential ones.  
 
In a minute I'll send a patch to darcs-devel that includes a test case this and 
includes this issue number in the patch name.

I'm sorry for the less-then-useful patch names. When I try to unrecord
in my darcs-stable repo, I get an error: 

   Fail: failed to read patch in get_extra:
   Fri Feb  4 07:37:49 EST 2005  David Roundy <droundy@abridgegame.org>
     * bump version number to 1.0.2 (at last!)
   Perhaps this is a 'partial' repository?

Shouldn't I be able to unrecord, even if /is/ a partial repo?

This is annoying--I'm not sure this is a darcs bug so much as a ghc bug.
But where there's a ghc bug that can be worked around, that's what we've
got to do.  The exception that is thrown (by ghc) really *ought* to include
the directory name.

Actually, I just checked, and my darcs *does* include the directory name:

Shall I pull this patch? (1/1) [ynWvpxqadjk], or ? for help: y

darcs failed:  user error (Error applying patch to working dir:
./d: createDirectory: already exists (File exists))
This may have left your working directory an inconsistent
but recoverable state. If you had no un-recorded changes
by using 'darcs revert' you should be able to make your
working directory consistent again.

What version of ghc was used to compile your darcs?

6.2.2. 

I suppose this gives me a concrete reason to upgrade, although I recall
that the last time I tried on FreeBSD, it was a hassle.

Anyway, it looks like you could close this darcs bug, since I believe
you already recommend 6.4.x.

Thanks for the response!

I'm closing this on the assumption that it's fixed with by ghc 6.4 on Mark's
suggestion.

David.
