Subject: New snapshot, binary available
23 Dec 1998 12:05:36 -0800 :
Message-ID: <19981223145156.A18932.cygnus.cygwin32.developers@cygnus.com>
Mime-Version: 1.0
To: cygwin32-developers AT cygnus DOT com

I've put up a new winsup snapshot in Geoff's winsup-snapshot directory:

ftp://ftp.cygnus.com/pub/noer/winsup-snapshot/

There's also a cygwin1.dll.bz2 there which is based on this snapshot.

The noticeable differences are:

1) Much reworking of serial handling.

2) gettimeofday works again.

3) configure --enable-threadsafe now will produce a threadsafe version
   of cygwin.  Thanks to Data Distilleries for providing the bulk of
   the work for this.

A caveat for the serial rehandling stuff:  There was a problem in
include/sys/termios.h where some constants for c_cflags overlapped
each other.  Rectifying this required renumbering some of the constants
and changing the sizes of some of the fields in termios.

Old programs should still work, but to avail yourselves of this fix
you'll need to recompile using the new include/sys/termios.h found in
the winsup snapshot.

The ChangeLog is below.

P.S. Best wishes to everyone on this holiday season!

Wed Dec 23 11:45:33 1998    <dj AT cygnus DOT com>

	* strace.cc (strace_microseconds): new function; returns elapsed
 	time in microseconds, using performance counters if available.
	(strace_vsprintf): print timestamps and deltas as microseconds,
 	not seconds.
	
Wed Dec 23 11:35:02 1998    <dj AT cygnus DOT com>

	* times.cc (__to_clock_t): Change return value to unsigned long
 	long to prevent overflow.
	
Tue Dec 22 19:37:55 1998  Christopher Faylor <cgf AT cygnus DOT com>

	* 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.
	* fhandler_serial.cc (fhandler_serial::fhandler_serial): Set size
	of data structure or suffer strange behavior on exec().
	(raw_read): Add debugging output.
	(fhandler_serial::init): New method.
	(fhandler_serial::open): Detect call from init method and avoid
	calling fhandler_base::open.  Don't worry about non-blocking reads
	since they are now handled correctly by _read().
	(fhandler_serial::tcsetattr): Honor ICANON in a kludgey sort of way.
	(fhandler_serial::tcgetattr): Ditto.
	(fhandler_serial::dup): New method.  Ensures duplication of all
	elements of fhandler_serial class.
	* fhandler_tty.cc (fhandler_tty_master::init): Reflect init argument
	reordering.
	(fhandler_tty_slave::init): Ditto.
	* hinfo.cc (hinfo::init_std_file_from_handle): Remove unnecessary
	argument.
	(hinfo_init): Reflect change to init_std_file_from_handle.
	(cygwin_attach_handle_to_fd): Use more appropriate types for
	arguments.
	(hinfo::build_fhandler): Add some slop to allocated buffer just
	for paranoia's sake.
	(hinfo::dup2): Avoid dereferencing a NULL pointer when oldfd==newfd.
	* 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.

Mon Dec 21 16:22:48 1998  Christopher Faylor <cgf AT cygnus DOT com>

	fork required' field.
	* fhandler_serial.cc (raw_read): Rewrite to come closer to handling VMIN
	VTIME parameters and to allow EINTR.
	(fhandler_serial::open): Initialize overlapped event here.  Make error
	messages more explicit.
	(fhandler_serial::close): Close status event.
	(fhandler_serial::tcsetattr): Store vtime_ as milliseconds.  Attempt to
	handle VMIN > 0, VTIME == 0 better.
	(fhandler_serial::fixup_after_fork): Initialize a new event handle after
	a fork.
	(fhandler_serial::de_linearize): Ditto.
