* dir.cc (__opendir_with_d_ino): Just call opendir. (opendir): Remove CYGWIN_VERSION_CHECK_FOR_NEEDS_D_INO handling. (readdir_worker): Only try generating d_ino if it's 0. Utilize namehash of directories fhandler. Call readdir_get_ino to generate d_ino for "..". (seekdir64): Keep dirent_set_d_ino flag. * fhandler.h (enum dirent_states): Add dirent_get_d_ino. (class fhandler_disk_file): Declare new private methods readdir_helper and readdir_9x. * fhandler_disk_file.cc (path_conv::hasgood_inode): New method to evaluate if a filesystem has reliable inode numbers. (fhandler_base::fstat_by_handle): Accomodate structure member name change from IndexNumber to FileId. (fhandler_base::fstat_helper): Call hasgood_inode here. (fhandler_disk_file::opendir): Call fhaccess only for real files. Don't append '*' to __d_dirname here, move to readdir_9x. On NT, open directory handle here. Set dirent_get_d_ino and dirent_set_d_ino flags according to wincap and filesystem. (fhandler_disk_file::readdir_helper): New method to implement readdir postprocessing only once. (readdir_get_ino_by_handle): New static function. (readdir_get_ino): New function to centralize inode number evaluation in case inode number hasn't been returned by NtQueryDirectoryFile. (fhandler_disk_file::readdir): Move old functionality to readdir_9x. Call readdir_9x when on 9x/Me. Implement NT specific readdir here. (fhandler_disk_file::readdir_9x): Move 9x specific readdir here. (fhandler_disk_file::seekdir): Accomodate new NT readdir method. (fhandler_disk_file::closedir): Ditto. (fhandler_cygdrive::fstat): Set d_ino to namehash. Add comment. (fhandler_cygdrive::opendir): Call get_namehash to prepare later correct evaluation of d_ino. (fhandler_cygdrive::readdir): Replace recursion with loop. Evaluate drive's d_ino by calling readdir_get_ino. * fhandler_proc.cc (fhandler_proc::readdir): Set dirent_saw_dot and dirent_saw_dot_dot to avoid seeing . and .. entries twice. * fhandler_process.cc (fhandler_process::readdir): Ditto. * fhandler_registry.cc (fhandler_registry::readdir): Ditto. * ntdll.h (STATUS_INVALID_PARAMETER): New define. (STATUS_INVALID_LEVEL): New define. (struct _FILE_INTERNAL_INFORMATION): Rename member IndexNumber to FileId (as in Nebbitt). * path.h (path_conv::hasgood_inode): Now implemented in fhandler_disk_file.cc. * wincap.h (wincaps::has_fileid_dirinfo): New element. * wincap.cc: Implement above element throughout. * winsup.h (readdir_get_ino): Add declaration. * include/sys/dirent.h (struct dirent): Slightly rename structure members to accomodate changes. Remove __USE_EXPENSIVE_CYGWIN_D_INO handling and declaration of __opendir_with_d_ino.
