(child_info_spawn::get_parent_handle): Declare new function.
* dcrt0.cc (child_info_spawn::get_parent_handle): Define new function.
(child_info_spawn::handle_spawn): Recreate parent handle if possible when
dynamically loaded. Don't mess with parent handle if it's NULL.
* spawn.cc (child_info_spawn::worker): Set parent_winpid appropriately.
* fhandler.h (PIPE_ADD_PID): Redefine to something we actually DON'T use.
* pipe.cc (fhandler_pipe::create): Avoid clearing all open_mode bits when
checking for PIPE_ADD_PID. Properly keep track of len so that passed in name
is not overwritten.
* pinfo.cc (pinfo::init): Reuse shared memory if the state is marked with
PID_REAPED.
* spawn.cc (child_info_spawn::worker): Don't duplicate myself_pinfo into
non-cygwin child.

* dcrt0.cc (child_info_spawn::handle_spawn): Keep parent open if we have
execed.
* pinfo.cc (pinfo::thisproc): Remove pid_handle manipulations.
(pinfo::init): Don't consider a reaped process to be available.
* spawn.cc (child_info_spawn::worker): Remove pid_handle manipulations. Make
wr_proc_pipe and parent noninheritable when starting a program which doesn't
use the Cygwin DLL. Conditionally reset wr_proc_pipe to inheritable if
CreateProcess fails. Inject wr_proc_pipe handle into non-Cygwin process.
Consider a non-cygwin process to be 'synced'.
* fhandler_tty.cc (bytes_available): Revert to previous Oct-2011 behavior where
a dummy buffer is used to determine how many bytes will be read.
(fhandler_pty_master::ioctl): Correct coercion in assignment.
systems. Change comment acordingly.
* wincap.h (wincaps::has_gaa_largeaddress_bug): New element.
* wincap.cc: Implement above element throughout.
(wincap_8): New globale wincaps to support Windows 8.
(wincapc::init): Take Windows 8 into account. Set new
has_gaa_largeaddress_bug member to false on 32 bit systems.
* sigproc.cc (proc_terminate): Don't set parent pid of child to 1 if we've
execed since the execed process is still considered the parent.
* child_info.h: Bump copyright.
* pipe.cc (fhandler_pipe::create): Don't indiscriminately add process id to
every pipe since some pipe names (fifo, tty) don't need it.
* sigproc.cc (sigproc_init): Pass PIPE_ADD_PID to fhandler_pipe::create to
ensure that pid is always part of sigwait pipe name.
* globals.cc (pipe_byte): Declare.
* pipe.cc (fhandler_pipe::create): Use current process id in pipe name rather
than pid for simple name collision avoidance. Do this only once to avoid extra
overhead when a busy pipe is found. Honor pipe_byte to create non-message
pipes if set.
* sigproc.cc (sigproc_init): Use a specific name for the signal pipe.
on-disk device and we were stating it.
* path.cc (path_conv::check): Set PATH_KEPT_HANDLE.
* path.h (path_types): Add PATH_KEPT_HANDLE.
(path_conv::kept_handle): Implement.
* dtable.cc (dtable::fixup_after_exec): Specifically reject releasing
nohandle() type fhandlers rather than relying on contents of io_handle.
(dtable::fixup_after_fork): Ditto.
* fhandler_termios.cc: Add includes necessary for definitions of have_execed
and have_execed_cygwin.
(fhandler_termios::sigflush): Don't flush console input when we've started a
non-Cygwin process.
* devices.in (exists_console): Use fhandler_console::exists () rather than raw
test.
* devices.cc: Regenerate.
* fhandler.h (fhandler_console::exists): Define new function.
* fhandler_console.cc (fhandler_console::need_invisible): Use
fhandler_console::exists () rather than raw test.
* spawn.cc: Rename assitant to assistant throughout.
(child_info_spawn::worker): Simplify test for when to start a non-Cygwin
process in its own process group. Just do it whenever we start a non-Cygwin
process.
ENOENT if non-existent file got opened for reading only. Explain why.
* path.cc (path_conv::check): Stick to ENOENT if file has been opened
for informational purposes only. Add to comment.
(getpass): Rework to use /dev/tty in the first place. Install
_getpass_close_fd as pthread cleanup handler. Flush prompt explicitely.
Lock input and switch off signal input handling when reading password.
(dev_on_fs): Set bit size.
(is_dev_resident): Define new method.
* devices.in: Use different method for labelling requested name for dev
storage: prefix it with a ='. Use an actual ':' to denote an internal device.
(exists_console): Avoid repeated test.
(exists_ntdev_silent): Rename from the less-descriptive exists_ntdevs.
(dev_dev_storage): Delete unneeded define.
* gendevices: Add a flag to each line denoting whether the device lives in /dev
space.
(generate): Handle special ":" case here for internal devices. Parse
=something_dev as requiring a storage location. Tack the rest of the line back
onto the reformulated "$rest".
* devices.cc: Regenerate.
* fhandler_dev.cc (fhandler_dev::readdir): Set st_ino to device number.
* syscalls.cc (fhandler_base::stat_fixup): Ditto. Fix link count for
CD-ROM devices. Fix typo in comment.
fhandler_base::set_ino_and_dev.
* syscalls.cc (fhandler_base::stat_fixup): Ditto. Accommodate name
change throughout. Fixup link count of console devices.
(DEV_CYGDRIVE_MAJOR): Remove.
(iscygdrive_dev): Define.
* dtable.cc (fh_alloc): Accommodate above change.
* path.cc (path_conv::check): Use iscygdrive_dev to check for cygdrive.
* syscalls.cc (fhandler_base::set_ino_and_dev): Drop check for
DEV_CYGDRIVE_MAJOR from conditional.
* syscalls.cc (fhandler_base::set_ino_and_dev): New method to set
st_ino, st_dev, and st_rdev for devices in a single spot.
(fstat64): Call fhandler_base::set_ino_and_dev instead of setting
st_ino, st_dev, and st_rdev here.
(stat_worker): Ditto.
