Writing to Windows Share issues fixed in cygwin1-20110829.dll.bz2

Writing to Windows Share issues fixed in cygwin1-20110829.dll.bz2

[Keith Christian]

I stumbled across the following snapshot, cygwin1-20110829.dll.bz2,
and now I can create files in a Windows Share that I haven't been able
to properly access from Cygwin in months!

Corinna, whatever changes you made to this snapshot have fixed the
problem for me, at least.  Hope they can be included in the next
official cygwin1.dll release.  Now I can start using the share from
Cygwin again.

Great news!

I was wrong.

Only some improvement using the cygwin1-20110829.dll.bz2 snapshot.
Problems still exist when trying to check in a file with RCS on this
Windows share.

Annotated test example below.  Apologies for not being brief.

Any ideas appreciated.  However, progress has been made with the 0829
snapshot, at least I can create files on this share......

That's weird.  The fact that you can create and write the _0qrsNBd
file shows that the write permission issue is fixed.  It seems that
renaming the file to testfile.1,v fails, but it's not clear why this
should happen.

What kind of share is that (/usr/lib/csih/getVolInfo /cygdrive/z)?

Does manual renaming the _0qrsNBd file work?

Does deleteing the _0qrsNBd file work?

Can you reproduce this situation from scratch and call the ci
command under strace, like this

  strace -o ci.trace ci -l -mfoo ./testfile.1

and send the strace output here?
