Hi,

i'm trying to use cygwin's cvs in server-mode for another application
I get the following error, but on a linux-system, everything is fine!

  E cannot mkdir /tmp/cvs-serv784/.
  error  No such file or directory

Please note, that the error is: "no such file or directory"
So i tested mkdir on the console:

  # mkdir /tmp/cvs-serv784/.
  mkdir: cannot create directory `/tmp/cvs-serv784/.': No such file or
directory
  # file /tmp/cvs-serv784/.
  /tmp/cvs-serv784/.: directory

As you can see, the file-command returns, that the directory
/tmp/cvs-serv784/ exists, but mkdir fails with "no such file or directory".

Well, you may say: that's OK, but it isn't! The correct error-message
should be something like "file or directory already exists"

I tested "mkdir /tmp/." on a linux-system, and it returns:

  # mkdir /tmp/.
  mkdir: cannot create directory `/tmp/.': File exists


Of course, cvs isn't using the mkdir command i guess, but it's using
some mkdir()-call and i guess that cygwin returns the wrong return-code
and actually cvs would ignore the "file exists" error-code, but it gets
the "no such file or directory" error-code.
So that results in a broken cvs :-(


Is this a bug in cygwin?


Greetings
  Sven


How to reproduce:

# mkdir /tmp/cvs
# cvs -d /tmp/cvs init
# cvs server

This creates a repository in /tmp/cvs and then starts a cvs in
server-mode. Then feed the cvs-command with the following lines:

Root /tmp/cvs
Global_option -n
Argument -d
Directory .
/tmp/cvs/
Argument .
Directory .
/tmp/cvs/
update
