newlib/winsup/cygwin/ChangeLog

2005-01-22  Christopher Faylor  <cgf@timesys.com>

	* pinfo.cc (pinfo::init): Move everything but the MapViewOfFileEx out
	of the loop since trying multiple times to call CreateFileMapping
	doesn't make much sense.  Try to structure the loop a little better so
	that exiting with a break does the right thing.
	(pinfo::release): Release shared memory area if it exists and close
	handle if it exists.

2005-01-22  Christopher Faylor  <cgf@timesys.com>

	* pinfo.cc (pinfo::maybe_set_exit_code_from_windows): Make sure that
	process has exited before getting an error code.
	(pinfo::exit): "cd" to innocuous location before exiting to make sure
	that process does not keep the current working directory busy while it
	is in the process of really exiting.

2005-01-18  Corinna Vinschen  <corinna@vinschen.de>

	* autoload.cc (CoInitialize): Remove.
	(CoUninitialize): Remove.
	(CoCreateInstance): Remove.
	(CoTaskMemFree): Add.
	(SHGetDesktopFolder): Add.
	* path.cc (shortcut_header): Remove.
	(shortcut_initalized): Remove.
	(GUID_shortcut): New static GUID.
	(struct win_shortcut_hdr): New struct describing Windows shortcut
	header structure.
	(symlink_worker): Rewrite creating Windows shortcuts.  Create
	ITEMIDLIST if target exists.  Only write once.
	(cmp_shortcut_header): Use win_shortcut_hdr structure for comparison.
	(check_shortcut): Rewrite to read only once from file.  Allow skipping
	an ITIMIDLIST in the file.

2005-01-16  Christopher Faylor  <cgf@timesys.com>

	* pinfo.h (maybe_set_exit_code_from_windows): Renamed from
	set_exit_state.
	* pinfo.cc (pinfo::exit): Use renamed function.
	(proc_waiter): Ditto.  Make a copy of input argument to avoid problems
	when procs array is shuffled.  Flag when copy is made so that
	remove_proc knows when it is safe to reshuffle.
	* sigproc.cc (proc_terminate): Don't flag process_state as PID_EXITED.
	(remove_proc): Wait for waiter to finish copying pinfo element before
	moving it (an actual wait should be an extremely rare event).

	* init.cc (dll_entry): Remove unused extern.

	* include/sys/cygwin.h: Remove PID_ZOMBIE.
	* pinfo.h: Rename EXITCODE_* defines.
	(pinfo::set_exit_state): Remove parameter.
	* pinfo.cc (set_exit_state): Remove parameter.  Reverse sense of test
	so that exitcode is checked for having been set rather than not having
	been set.  Set flag when exitcode has been established.  Don't set
	PID_STATE here.
	(pinfo::init): Remove exitcode initialization.
	(pinfo::exit): Reflect change in EXITCODE_* naming.  Set flag when
	exitcode has been established.  Reflect change in arguments to
	set_process_state.
	(proc_waiter): Reflect change in arguments to set_process_state.  Set
	process_state here and only here.
	* fhandler_process.cc (fhandler_process::fill_filebuf): Reflect removal
	of PID_ZOMBIE define.
	(format_process_stat): Ditto.
	(format_process_status): Ditto.
	* sigproc.cc (pid_exists): Ditto.

2005-01-15  Christopher Faylor  <cgf@timesys.com>

	* path.h (path_conv::path_conv): Fill path with native device
	name in case of device argument.

2005-01-13  Corinna Vinschen  <corinna@vinschen.de>

	* fhandler_serial.cc (fhandler_serial::dup): Call overlapped_setup
	for child, not for parent.

2005-01-13  Christopher Faylor  <cgf@timesys.com>

	* init.cc (dll_entry): Nuke attempt to set exit code since parent will
	use windows exit code if needed.
	* pinfo.cc (pinfo::exit): Move release() here to minimize pid creation
	race (suggested by Pierre Humblet).

2005-01-12  Christopher Faylor  <cgf@timesys.com>

	failure.

	process_state.

	-- it is not an error.
	(child_info::sync): Don't set exitcode here.  Assume that will happen
	in proc_waiter, if necessary.
	* spawn.cc (spawn_guts): Delay "wait_for_myself" logic until later.
	Don't wait at all if the process has already exited.  Reflect movement
	to pinfo::exit.

	* environ.cc (build_env): Disallow empty strings and strings starting
	with '=' in Win32 environment.

2005-01-08  Pierre Humblet <pierre.humblet@ieee.org>

	(cygthread::cygthread): Actually pass name as argument to debugging
	output to avoid SEGV when strace'ing.

	once on first entry to a stub not on each stub iteration.
	(cygthead::exit_thread): Remove obsolete function.
	* cygthread.h (cygthread::exit_thread): Ditto.

2005-01-01  Christopher Faylor  <cgf@timesys.com>
