- Allow to use advisory locking on any device. POSIX fcntl and lockf locking
works with any device, BSD flock locking only with devices backed by an OS
handle. Right now this excludes console windows on pre Windows 8, as well as
almost all virtual files under /proc from BSD flock locking.
* devices.in (dev_storage): Map /dev/zero and /dev/full to \Device\Null. * devices.cc: Regenerate. * dtable.h (struct dtable): Make fhandler_base friend, rather than fhandler_disk_file. * fhandler.cc (fhandler_base::open_with_arch): Create unique id. (fhandler_base::cleanup): Call del_my_locks. (fhandler_base::fcntl): Handle F_GETLK, F_SETLK and F_SETLKW. * fhandler.h (fhandler_base::get_dev): Return real device number. (fhandler_base::set_unique_id): New inline method. (fhandler_disk_file::lock): Drop declaration. (fhandler_disk_file::get_dev): New method, return pc.fs_serial_number. (fhandler_dev_zero::open): Drop declaration. * fhandler_disk_file.cc (fhandler_disk_file::close): Move del_my_locks call to fhandler_base::open_with_arch. (fhandler_disk_file::fcntl): Move handling of locking commands to fhandler_base::fcntl. (fhandler_base::open_fs): Drop call to NtAllocateLocallyUniqueId. * fhandler_zero.cc (fhandler_dev_zero::open): Remove so that default fhandler_base::open is used to open \Device\Null. * flock.cc (fixup_lockf_after_exec): Finding a single fhandler is enough here. (fhandler_base::lock): Replace fhandler_disk_file::lock. Refuse to lock nohandle devices. Handle read/write test using POSIX flags. Explain why. Never fail on SEEK_CUR or SEEK_END, rather assume position 0, just as Linux. * net.cc (fdsock): Create unique id.

* exception.h: Fold in content of include/exceptions.h. * include/exceptions.h: Remove.
2013-10-27 17:42:17 +08:00
- The header /usr/include/exceptions.h, containing implementation details for
32 bit Windows' exception handling only, has been removed.

Fixes: http://cygwin.com/ml/cygwin/2013-09/msg00155.html
* fhandler_process.cc (format_process_ctty): Fix random content of /proc/$PID/ctty if the process has no controlling tty. Set to just "\n" instead.

- Properly set process sid rather than always using -1.
Fixes: http://cygwin.com/ml/cygwin/2013-10/threads.html#00237
* fhandler_clipboard.cc (fhandler_dev_clipboard::open): Drop gratuitios handling of membuffer. It's NULL anyway. (fhandler_dev_clipboard::lseek): Set membuffer to NULL after freeing it to avoid subsequent crashes when accessing invalid pointer.
2013-10-25 23:04:24 +08:00
- Fix a potential crash after calling lseek on /dev/clipboard.
* devices.in (dev_storage): Map /dev/dsp to \Device\Null. * devices.cc: Regenerate. * fhandler_dsp.cc (fhandler_dev_dsp::open): Call fhandler_base::open. (fhandler_dev_dsp::close): Call fhandler_base::close. (fhandler_dev_dsp::fixup_after_fork): Call fhandler_base::fixup_after_fork. * fhandler_raw.cc (fhandler_dev_raw::fixup_after_fork): Call fhandler_base::fixup_after_fork.

- Fix a handle inheritance bug in raw disk and tape device handling which
led to EBADF errors in child processes.

- open("/dev", O_CREAT) accidentally created a /dev file if no /dev
exists at the time.
- DIR *d = opendir ("foo"); flock (dirfd (d), ...); worked, but did the
wrong thing.
- Reading from /dev/windows was broken for some time.
- select'ing on /dev/windows accidentally didn't take the setting of
ioctl (WINDOWS_HWND) into account.
