    Problem Text

    In the test program: ~/SRC/common/tsetlib/setupnospc.c:

    /*
    * Delete all files that (may or may not) have been created
    */
    for (i = nfile; i > 0; i--)
    {
    (void) strcat(strcpy(name, base), "/fill.tmp");
    (void) strcat(name, itoa(i));
    > (void) unlink(name);

    (void) strcat(strcpy(name, base), "/fill.dir/fill.tmp");
    (void) strcat(name, itoa(i));
    > (void) unlink(name);
    }

    When MKDIR_TEST case is executing fill.tmp is a directory. Then the
    following problem arises:

    If unlink() is used on a directory that is empty (contains only the
    files . and ..), the directory is unlinked, but the parent directory's
    link count is left with an inaccurate value.

    In the above case, the file system should be checked using fsck. To avoid
    these types of problems, use rmdir() instead of unlink().

    So, the code should take care of the case when fill.tmp will be a
    directory. The suggested code change is listed below:

    /*
    * Delete all files that (may or may not) have been created
    */
    int rval;

    for (i = nfile; i > 0; i--)
    {
    (void) strcat(strcpy(name, base), "/fill.tmp");
    (void) strcat(name, itoa(i));
    if ((rval = rmdir(name)) == -1)
    (void) unlink(name);

    (void) strcat(strcpy(name, base), "/fill.dir/fill.tmp");
    (void) strcat(name, itoa(i));
    if ((rval = rmdir(name)) == -1)
    (void) unlink(name);
    }
    Test Output

    /tset/POSIX.os/files/rmdir/T.rmdir 9 Unresolved

    Test Description:
    When the directory's link count becomes zero and no process has the
    directory open, the space occupied by the directory shall be freed and
    the directory shall no longer be accessible.
