I have an ext2 filesystem where I store my repositories, and I'm it sharing
between Linux and XP on a dual-boot system. The drive is being shared via
Ext2IFS (http://www.fs-driver.org/). This is causing Darcs to crash:

('M:' is the Ext2 filesystem mounted into XP with http://www.fs-driver.org/)
----------------------------------------------------------------------------------------
M:\> md TEST

M:\> cd TEST

M:\> edit aaa

<Create some trivial content>

M:\> darcs init

M:\> darcs add aaa

M:\> darcs record -a -m init

<Darcs prompts for email address, then ...>

darcs: ./aaa-0: renameFile: already exists (File exists)

After this, "darcs w -ls" continues to show:

A ./aaa

So I cannot check-in "aaa".
----------------------------------------------------------------------------------------

I suspect its a problem with darcs (maybe unexpected semantics of Ext2IFS?),
since I've used svn, bzr, and mercurial in the same scenario with no issues,
but I'm sending this to the author of Ext2IFS as well.

Resolving on Frank's followup (issue470).  Cheers,

What happens on the Ext-2 filesystem when you create two files called
``a'' and ``b'' and then try to do

    ren a b

?

It says:

"A duplicate file name exists, or the file
cannot be found."

The contents of "a" and "b" are unaffected.

Hmm, is that normal behaviour under Windows?  What happens when you do
the same test on an NTFS filesystem?

                                        Juliusz

The same thing happens on NTFS. And yes, that is the normal behavior.

I've very curious, what behavior were you expecting?

With no further feedback from the requestor in over six months, I'm marking this
as "wont-fix" for. (More like "presumed-dead"). No one else has reported a dupe
during that time.

It was confirmed to be a bug in ext2ifs. I thought I had reported that, but
see now that I did not. Sorry about that!
