Subject: New snapshot

Message-ID: <19981126010059.A11779.cygnus.cygwin32.developers@cygnus.com>
Mime-Version: 1.0
To: cygwin32-developers AT cygnus DOT com

I've put up a snapshot of my current work on eliminating the configure
pause problem (perhaps you've heard of it?).  You can get it at:

ftp://cambridge.cygnus.com/pub/cygwin/

There is also a pre-built DLL there.

I'd be interested in hearing if you think that the configure
pause is gone, worse, the same, more erratic, etc.

Sergey has reported a couple of problems with this snapshot:

1) gcc -pipe has a 10% performance loss.

2) It doesn't work with Midnight Commander.

On the other hand, #! stuff should work better...

With this snapshot, TERM is also set to `cygwin' by default if TERM is
initially not set.  There was some discussion about using different
values for this.  It turns out that only `linux' or `cygwin' are
appropriate.  There are also termcap sources, a libtermcap.a.bz2, and a
new termcap data file (which differs only in the inclusion of a cygwin
alias) at the above location.

The ChangeLog is below.

And, finally, a belated Happy Thanksgiving to everyone!

	* winsup.h: Make `isdirsep' an alias for SLASH_P.
	Implement isabspath convenience macro.
	Change sigprotect to a macro since it appears to
	be impossible to send __FILE__ type macros to a
	constructor.  Change use of sig_protect throughout.
	* dcrt0.cc (dll_crt0_1): Use new path macro.
	* dlfcn.cc (get_full_path_of_dll): Ditto.
	* path.cc (path_conv::path_conv): Ditto.
	(normalize_posix_path): Ditto.
	(slashify): Ditto.
	(backslashify): Ditto.
	* syscalls.cc (num_entries): Ditto.
	* lock.cc: Redefine lock methods to pass debug info to
	{get,release}_signal_mutex.
	* environ.cc (environ_init): Correct strncmp test for
	TERM=, otherwise it's impossible to set TERM.
	* exceptions.cc: Eliminate lock_cs and unlock_cs macros.
	Use {get,release}_signal_mutex throughout.
	(signal_init): Don't initialize signal_mutex here.
	(set_process_mask): Remove vestiges of old mutex code.
	(handle_sigsuspend): Ditto.
	(call_handler): Move signal_arrived SetEvent back here.
	It was being triggered too often before.
	Detect when the signal thread is exiting.
	(sig_handle): Remove inappropriate SetEvent(signal_arrived).
	(events_terminate): Move close of signal_mutex elsewhere.
	* glob.cc: Increase "MAXPATHLEN" size for arguments that
	are not necessarily pathnames.
	* pinfo.cc (lpfu): Lower timeout for reporting possible
	problem with INFINITE wait.
	* sigproc.cc (wake_wait_subproc): Make this a macro with
	no arguments so that its use in the code is a little
	clearer.
	(proc_terminate): Eliminate signal blocking here since
	this should already be handled by the caller.
	(sigproc_init): It makes sense to initialize signal_mutex
	here, so do so.
	(__allow_sig_dispatch): Rename.  Take debugging arguments.
	Pass arguments on to release_signal_mutex.
	(__block_sig_dispatch): Rename.  Take debugging arguments.
	Pass arguments on to get_signal_mutex.  Detect signal
	thread exiting confition.
	(__get_signal_mutex): Take debugging arguments.  Maintain
	a stack of nested mutex calls for later display in
	__release_signal_mutex.  Detect signal thread exit
	condition.  Don't bother with locking if signal thread is
	executing or if just an exec stub.
	(__release_signal_mutex): Don't bother with locking if signal
	thread is executing or if just an exec stub.
	* sigproc.h: Reflect renamed functions above.  Provide
	wrappers to pass in diagnostic information.
	* spawn.cc (spawn_guts): More fixes to deal with nested
	#! and to properly report posix argv[0] when invoked as a
	script.

Wed Nov 25 12:41:12 1998  Christopher Faylor <cgf AT cygnus DOT com>

	* Makefile.in: Reinstate libwinspool.a/winspool.drv creation.

Tue Nov 24 18:48:56 1998  Geoffrey Noer  <noer AT cygnus DOT com>

	* Makefile.in: add CFLAGS_COMMON and CFLAGS_CONFIG to CFLAGS
	and CXXFLAGS in FLAGS_TO_PASS.

	* include/sys/select.h: new file with select proto.  Avoid
	potential conflict with Winsock inclusion by Cygwin internals.
	* include/sys/socket.h: remove select proto.
	* winsup.h: define __INSIDE_CYGWIN__.  Include windows.h after
	Unix include files.
	* include/mywinsock.h: delete file
	* include/Windows32/Sockets.h: add ndef __INSIDE_CYGWIN__s
	around portions that conflict with Unix definitions.  This
	yields what used to be mywinsock.h which is a blend of Unix
	sockets and Winsock needed by Cygwin internals.
	* exceptions.cc: define Win32_Winsock to include
	Windows32/Sockets.h.  No longer define __INSIDE_CYGWIN__.
	* hinfo.cc: ditto
	* net.cc: ditto
	* select.cc: ditto

	* include/exceptions.h: change wrapper define to _EXCEPTIONS_H.

	* smallprint.c (__small_vsprintf): Ditto.
	* tty.cc (tty::get_event): Ditto.
	* winsup.h: Give up on read_ready_thread.  Move sig_protect
	here since it needs to use information set up after the sigproc.h
	include.
	* dcrt0.cc: Ditto.
	* debug.cc (WFSO): New function.  Used to ensure that
	function shows up on stack trace.
	(WFMO): Ditto.

	automatic variable.
	(find_exec): Always point known_suffix to something.
	* syscalls.cc (read_handler): Refine debug output.
	(read_ready_thread): Delete.
	(_read): Eliminate use of read_ready_thread.  Call ready_for_read
	directly as appropriate.

Thu Nov 19 15:26:40 1998  Geoffrey Noer  <noer AT cygnus DOT com>

	* Makefile.in: remove -Wunused since that's already in -Wall

	More minor cleanup:

	* fork.cc (sync_with_parent): should NOT use rc since
	this is a macro and that could have interfered with rc in
	the calling function.  Renamed to psync_rc.
	* fhandler_serial.cc (fhandler_serial::open): change
	access to myaccess since it shadows global decl.
	* hinfo.cc: ditto throughout
	* path.cc: ditto throughout
	(path_conv::path_conv): change error to err.

Wed Nov 18 16:17:58 1998  Geoffrey Noer  <noer AT cygnus DOT com>

	to path_conv.
	(fhandler_disk_file::open): Ditto.

Mon Nov 16 16:15:20 1998  Geoffrey Noer  <noer AT cygnus DOT com>

	* Makefile.in: FLAGS_TO_PASS should pass CFLAGS and CXXFLAGS
	not ALL_CFLAGS and ALL_CXXFLAGS.  Rework handling of CFLAGS
	variables to remove duplication and make it possible to
	build mingw directory.

Mon Nov 16 09:40:21 1998  Christopher Faylor <cgf AT cygnus DOT com>

	* syscalls.cc (_open): Use new macro to check for
