File Permission Problems on Windows XP, cygwin 1.3.22


Hello,

I am serving a cvs repository from a Windows XP Professional machine under
Cygwin 1.3.22 and I believe that I am having a file permissions problem in
the cvs repository.  My repository is located at /cvs and all cvs users
belong to the "cvs" group as their primary group.  All directories in the
repository have rwx permissions for this group as well as for the owner.
Therefore, I should be able to replace the ,v files with a new version as
part of a commit for any users in the cvs group.  However, only the owner of
each ,v file (i.e. the developer that added or last modified the file) can
successfully commit.  The CYGWIN environment variable is set to 'ntsec'.

When I commit files from a user that is not the owner of the file the commit
fails as follows:

cvs -t commit -m "try commit" readme.txt (in directory C:\dev\bar)
cvs commit: notice: main loop with CVSROOT=:ext:markp@192.168.2.105:/cvs
 -> Starting server: plink.exe 192.168.2.105 -i

S-> Parse_Info (/cvs/CVSROOT/verifymsg, bar, not ALL)
S-> checkout (/cvs/bar/readme.txt,v, 1.1, -ko, /tmp/cvs003472)

cvs [server aborted]: cannot rename file /cvs/bar/,readme.txt, to
/cvs/bar/readme.txt,v: Permission denied
S-> unlink_file(/cvs/bar/,readme.txt,)
S-> Lock_Cleanup()

I have seen this error message discussed on the cvs mailing list archives
but those discussion were only relevant for cases where people hosted the
repository on a network share.  My /cvs repository is in a local hard disk
directory.

When I try to emulate a file move as this same user, markp, directly in the
repository at the cygwin command prompt I experience the same permission
error as follows:

markp@markonius /cvs/bar

$ mv tmp readme.txt,v

markp@markonius /cvs/bar
$ echo $CYGWIN

markp@markonius /cvs/bar


When I perform this same operation as the file owner the attempt succeeds
(and so does a regular CVS commit operation) as follows:

cvsuser@markonius /cvs/bar
$ id
uid=1016(cvsuser) gid=1015(cvs) groups=513(None),545(Users),1015(cvs)

I have attached the results of cygcheck to this email and I have the CYGWIN
environment variable set to 'ntsec'.

Please help me understand what is wrong with my repository file permissions.

Thanks,
Mark
