cygwin, 著名的在win32下模拟unix操作系统的东东

Thu Dec 31 16:50:32 1998  DJ Delorie  <[e-mail]>

	signed vs. unsigned, char * vs. const char *, etc...

Wed Dec 30 21:41:25 1998  Christopher Faylor <[e-mail]>

	* dcrt0.cc (do_exit): Remove previous dwProcessId
	change as it presumes too much knowledge about signalling
	in the wrong place in the code.
	* sigproc.cc (sigproc_terminate): Move the dwProcessId
	assignment here but only do it when it is necessary or
	programs will die abnormally.
	* fhandler.h: Add raw_write method to fhandler_serial.
	* fhandler_serial.cc (raw_write): New method.  Accommodates
	overlapped I/O that now must be used with serial.

	for existence of process.

Wed Dec 30 00:01:18 1998  Geoffrey Noer  <[e-mail]>

	* include/cygwin/version.h: bump API_MINOR to 8 to mark
	recently exported _ctype_, _sys_errlist, _sys_nerr.  Briefly
	describe all API_MINOR changes to date.

Wed Dec 30 01:31:34 1998  Christopher Faylor <[e-mail]>

	* dcrt0.cc (do_exit): Set myself->dwProcessId so that
	some exit routines will not falsely believe that this
	process has been execed.
	* select.cc (peek_serial): Remove debugging statements.
	* sigproc.cc (sigproc_terminate): Detect state where
	myself->dwProcessId == 0 as indicative of not being

Mon Dec 28 22:02:15 1998  Christopher Faylor <[e-mail]>

	* fhandler.h: Make fhandler_serial io_status public since
	select needs it.  Add 'saw_error' field to select_record so
	that select can detect error conditions.
	* fhandler_serial.cc (fhandler_serial::raw_read): Detect
	"operation aborted" error and retry.  This seems to indicate
	an attempt to retry an overlapped operation.
	* select.cc (select_stuff::wait): Honor saw_error field when
	appropriate.
	(peek_serial): Rewrite to operate similarly to
	fhandler_serial::raw_read.
	* include/sys/termios.h: CBAUD mask was still not right.

	* errno.cc: Move _sys_errlist and _sys_nerr here.
	* dlfcn.cc: Reorganize includes to put ctype.h after winsup.h

	it conflicts with TIOCPKT.
	* passwd.cc (passwd): Bypass tc[gs]etattr call in favor of appropriate
	method or conversion confusion will result due to attempts to
	appropriately convert to old-style termios structures in tc[gs]etattr.

	* termios.cc (tcsetattr): Reorganize to allow meaningful debugging

	long to prevent overflow.

	* fhandler.h: Reflect fhandler_*::init argument reordering.
	Add dup and init methods to fhandler_serial.
	* fhandler.cc (fhandler_base::init): Reorder arguments to mirror
	open().
	* fhandler_console.cc (fhandler_console::init): Ditto.  Initialize
	using fhandler_base rather than fhandler_serial as console is
	now being slowly uncouple from fhandler_serial.

	of data structure or suffer strange behavior on exec().

	* pipe.cc (make_pipe): Reflect init argument change.
	* shared.h: Another immigrant from winsup.h
	* winsup.h: Reflect change to init_std_file_from_handle.  Relocate
	a declaration to shared.h so that it can be used in fhandler.h.
	* include/sys/cygwin.h: Reflect change to cygwin_attach_handle_to_fd.
