    /tset/POSIX.os/files/mkdir/T.mkdir 12 Unresolved

    Test Description:
    If {_POSIX_LINK_MAX} F {LINK_MAX} F {PCTS_LINK_MAX}, then EMLINK in
    errno and a return value of -1 on a call to mkdir(path, mode) when
    {LINK_MAX} links to the parent directory already exist. No directory
    shall be created,
    otherwise
    {PCTS_LINK_MAX} links can be created to the parent directory.
    Note: For XNFS testing, the value for {LINK_MAX} is determined on the
    server.

    Review Response
    In our response to a previous request regarding mkdir test 8 we have suggested
    that the SPEEDFACTOR should be manually increased before the test suite is
    compiled and run. This work around should resolve the problems affecting this
    test and it should not be necessary to obtain a waiver.

    I would suggest that this request is refused, but recognise that it may need
    to be resubmitted and granted in the case that the increase in SPEEDFACTOR
    does not resolve the problem in the other tests.

    Review Conclusion
    This problem is a combination of two unusual conditions on our
    platform. The PATH_TRACE statement that is not being executed is
    the one inside the loop creating {testmax} directories.

    The reason the loop is not creating any directories is a combination
    of two unusual conditions on our platform. Our NGRPS_MAX is 300 and
    LINK_MAX is 65536. Test 12 of POSIX.os/files/mkdir will create no
    more than 256 directories because our LINK_MAX is so high. The
    directory the test will create the files in is
    TESTROOT/tset/POSIX.os/files/mkdir/d.mkdir. This directory is also
    used for test 8 of POSIX.os/files/mkdir and because our NGRPS_MAX is
    300, the following happens:

    o a timing problem in test 8 causes the test to terminate after
    after creating somewhat less than NGRPS_MAX directories in d.mkdir
    (this will be the subject of another test suite deficiency
    request).

    o since test 8 terminates abnormally, the directories it creates
    are not cleaned up

    o the fact that these directories are still around affects the
    processing of test 12.

    It is simply a matter of chance that if test 8 creates more than 256
    directories but less than NGRPS_MAX, it will produce this side effect
    in test 12. If test 8 is corrected, test 12 should operate correctly.
