    Problem Summary TIN4C.00049 The submitter claims this test should not expect LARGE/find1019a.tmp to appear in the list of files printed to stdout.
    Problem Text

    The test 1019 incorrectly validates the "LFS: find with inaccessible operand"`
    assertion. The test case creates a subdirectory find1019a.tmp under a directory
    for this test example will be called LARGE. The test case then creates another
    subdirectory find1019b.tmp under LARGE and the a file 1019d.tmp under this
    subdirectory resulting in a path ./LARGE/find1019b.tmp/1019d.tmp. The
    subdirectory ./LARGE/find1019a.tmp has its permissions set to 000 which is
    unsearchable. The test case then executes the following command:

    find ./LARGE/find1019a.tmp ./LARGE/find1019b.tmp -print

    The first expected result is ./LARGE/find1019a.tmp to be printed to stdout
    which is incorrect this directory unsearchable and only an error message of
    unable to read the directory should be written to stderr.

    Review Response
    We recommend this request be refused.

    We believe the test is correct as written.

    Using the example the submitter presents, ./LARGE/find1019a.tmp
    should be printed to stdout. It and ./LARGE/find1019b.tmp are both
    entries in the directory, LARGE. Since LARGE is searchable, they may
    both be found. Since both are found they both must be printed.

    It is the contents of ./LARGE/find1019a.tmp which will not be
    printed. The test correctly anticipates this.

    Review Conclusion
    We are granting a Temporary Interpretation to move this
    issue forward. It should also go for a 14 day review with
    the Base Working Group. We recommend a Permanent Interpretation.

    The specification appears to not be specific on this issue and
    existing implementations perform in different ways.

    For example:
    mkdir tmpdir
    mkdir tmpdir/subdir
    chmod 000 tmpdir/subdir
    find tmpdir -print

    Some implementations print out

    tmpdir
    tmpdir/subdir
    find: tmpdir/subdir: Permission denied

    others print out

    $ find tmpdir -print
    tmpdir
    find: Cannot read dir tmpdir/subdir: Permission denied

    Review Resolution No Resolution Given
    Review Conclusion
    The group agrees with the X/Open initial response that a permanent
    interpretation should be granted. However since this wording is
    from POSIX.2 a POSIX interpretation request should be filed -
    so this should remain as a TIN until that request is resolved.
