It appears as though there is a problem using the /cygdrive/m type paths inside MVFS when there are extremely large dependency trees.
Unless you can point to problems with a standard, supported W2K filesystem, please don't expect anyone to try to fix this.
Cygwin uses standard Win32 APIs for detemining if something is a directory. If those APIs are not working for Clearcase then it is unlikely that anyone will be motivated to fix the problem on the Cygwin side.
The OP was suggesting both a problem determining if something is a directory and a problem related to pathnames. Running strace my shed some light on the root cause.
Would it have made you feel better if I had said "for dealing with paths and determining if something is a directory"?
The "related to pathnames" was refering to the last paragraph in the initial
post, which points to Cygwin (although I can't imagine how):
" As shown above, using vpath . ../.. /cygdrive/m/top fails, even
though it should work. Using vpath . /cygdrive/m/top fails with the same
errors as above. However, vpath . M:/top succeeds in the dependency
check, even though M:/top should apparently be written as /cygdrive/m/top
to comply to cygwin standards."
If the OP is willing to do this then I hope he does it on a standard filesystem like NTFS, as I originally suggested. If there is a problem there then it is obviously not a ClearCase problem.
Right. But then if it is a ClearCase problem, it can't be identified... My request would be to trace under the latest Cygwin.
BTW: Can someone provide testcode to identify if the current drive as MVFS please. At least I think that a clearcase view is mounted as driveletter.
Does it show up as GetLogicalDrives()? (should so)
In detail, what does GetVolumeInformation().lpFileSystemNameBuffer return for such a MVFS drive?
