Thu Dec 18 12:30:47 1997  Ian Lance Taylor  <ian@cygnus.com>

	* fhandler.h (class fhandler_base): Remove inline definitions of
	tcflush, tcsendbreak, tcdrain, tcflow, tcsetattr, tcgetattr,

	Allow Cygwin32 to terminate process even when in a blocking
	winsock call.
	* exceptions.cc (call_handler): call to WSACancelBlockingCall()
	removed.
	(sighandle): call WSACleanup() before exiting the process to

Thu Dec 11 15:14:40 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* sigproc.cc (proc_subproc): Remove over-enthusiastic test for
	process handling readiness or proc_wait will loop attempting to
	handle a dying subprocess when signal handlers are not ready.
	* fork.cc (cygwin_fork_helper1): Reorganize to ensure that a
	forked process is capable of receiving signals when fork()
	returns.

Wed Dec 10 15:43:37 1997  Ian Lance Taylor  <ian@cygnus.com>

	* include/sys/termios.h (IXANY): Correct value.
	(PARMRK): Define again.

Wed Dec 10 00:05:23 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
        * dcrt0.cc (dll_crt0_1): Move start time initialization to a more
	logical place (pinfo_init).
        (do_exit): Reorganize to attempt to solve races when a cygwin
	process occupies two windows pids (i.e., an execed process).
	* exceptions.cc (lock_cs): Fix erroneous WFSO logic.
	(sighandle): Use new method for determining if process was
	initiated via fork.
	(events_terminate): Do not close pinfo_mutex.  Allow automatic
	close by ExitProcess to lengthen the time that the pinfo structure
	is locked, minimizing races between an exiting child and a
	potentially exiting parent.
	* hinfo.cc (hmap_init): Use new method for determining if process
	was initiated via fork.
	(hinfo_vec::de_linearize_fd_array): Fix a typo in a comment.
	* pinfo.cc (clearout): Remove this function.  Handled in
	allocate_pid.
	(pinfo_init): Move start_time setting here from dll_crt0_1.
	Remove call to init_self in favor of adding three additional lines
	of code.
	(pinfo_list::operator []): Implement a very simple hashing
	scheme for pid lookup.
	(lpfu): New routine controlled by DEBUGGING conditional.  When
	DEBUGGING is activated, lpfu returns more information about the
	state of a timed out pinfo_mutex.
	(pinfo_list::get_empty_pinfo): Remove function.  Move
	functionality to allocate_pid.
	(allocate_pid): Implement a (very) simple hashing scheme for
	finding an available pid.  Take advantage of reorganized pinfo
	structure to zero all pertinent fields with one memset.
	(pinfo::record_death_nolock): Don't bothering zeroing
	inconsequential stuff.
	(pinfo::record_death): Leave pinfo_mutex locked with the
	understanding that this function will be called just prior to
	exiting the process.  This minimizes a race between a child which
	is exiting at nearly the same time as its parent.
	* sigproc.cc: Reformat function calls.
	(sigproc_init): Clear new PID_INITIALIZING flag to indicate that
	a (possibly execed) process is now capable of receiving signals.
	(sig_send): Be more defensive in determining if a signal can be
	sent to myself or suffer problems with execed processes.
	(sigproc_terminate): Wait for sig_proc to exit to ensure that
	all pending signals have been handled.  Use new 'proc_terminate'
	function to terminate the subprocess handling thread.
	(allow_sig_dispatch): Don't bother blocking signals if signal
	handling isn't active in this process yet.
	(block_sig_dispatch): Don't bother blocking signals if signal
	handling isn't active in this process yet.
	(sig_proc): Use sig_loop_wait variable to control wait time for
	signal semaphores.  Uncouples this wait from wait_subproc.
	Perform signal cleanup here on thread termination.
	(proc_exists): More accurate tests to determine if a process
	really exists.
	(proc_register): Remove this function in favor of a macro.
	(proc_subproc): More stringent test for being "ready" to process
	subprocesses.  Add more common initialization to PROC_ADDCHILD.
	Remove PROC_EXIT in favor of a separate function.
	(proc_terminate): New function.  Replaces PROC_EXIT functionality
	in proc_subproc.  Terminates subproc handler thread.
	(stopped_or_terminated): use lock_pinfo_for_update when modifying
	child stopsig status or suffer a race.
	(wait_subproc): Save sig_proc thread handle away for
	synchronization when exiting.  Set up 'i_am_alive' mutex inherited
	by childen.  Child's inability to lock this mutex means that the
	parent is still alive and processing children.  Use proc_loop_wait
	to control WFMO.  Clean up events queue on thread exit.
	(zap_subproc): Clear out pinfo structure for a child.
	* sigproc.h: Remove PROC_EXIT constant.  Remove obsolete
	proc_register declaration.
	(alive_parent): New macro to determine if a parent is still alive.
	* spawn.cc (spawn_guts):  Fix a comment typo.  Use proc_terminate
	to terminate all subprocess handling prior to an exec.  Use new
	method for determining if this process was started via a fork.
	Attempt to clean up races between execed process, its parent, and
	the execed child.
	* winsup.h (pinfo): Add a new handle indicating that a parent is
	alive.  This should be a foolproof way of determining if a parent
	has gone away so that a child will know whether to remove itself
	from the pinfo table.
	Reorganize the structure in such a way that items to be zeroed
	are grouped together at the beginning for more efficient zeroing
	in allocate_pid.
	Add a new PID_* constant.
	New lock_pinfo_for_update macro for use when debugging cygwin.

Wed Dec 10 00:05:23 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	Change the way to inherit fd table on spawn/exec calls.
	Use STARTUPINFO structure to pass an fd table to a child process
	instead of shared memory area.  This is undocumented, but is used
	by MSVC runtime.  The desktop inheritance code added again,
	otherwise user32.dll will fail to initialize after sexec calls.
	* pinfo.cc (pinfo_init): delinearize fd array from STARTUPINFO
	structure instead of call to copy_shared_fd_table.
	* shared.cc (create_shared_fd_mapping_name): remove
	(create/copy_shared_fd_table): remove
	* spawn.cc (spawn_guts): use lp(cb)Reserved2 fields of STARTUPINFO
	to pass fd table to a child.  Remove call to
	create_shared_fd_table.  Inherit window station/desktop on sexec
	calls.
	* winsup.h: remove prototypes for create/copy_shared_fd_table.

Fri Dec  5 18:57:42 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* kill.cc (main):  Report error if kill() fails.  Minor reformat.
        * ps.cc (main):  Only use month/day in start time when starting
        time is > 24 hours in the past, not when it occurs yesterday.

Fri Dec  5 15:54:41 1997  Geoffrey Noer  <noer@cygnus.com>

	* fcntl.cc (_fcntl): reformat
	* fhandler.cc (fhandler_tty::open): new, need special open for
	ttys.  In addition to calling fhandler_base::open, check
	flags to handle blocking vs. non-blocking I/O.  Should
	initialize tty to standard state (9600 bits/sec - 8 - 1 with
	no flow control) but this code needs more work still.  Ifdef
	out for now.
	(fhandler_tty::tcsendbreak): new
	(fhandler_tty::tcdrain): new
	(fhandler_tty::tcflow): new
	(fhandler_tty::tcsetattr): add support for action arg.  Use
	a DCB struct to hold the values we will set.  First call
	GetCommState to get the current state, then reassign values
	based on the contents of the termios struct.  Handle the
	case where t->c_ospeed is set to B0, otherwise set state.BaudRate.
        Set all the other DCB struct values appropriately, based on
        the contents of the termios struct.
	(fhandler_tty::tcgetattr): do the inverse of tcsetattr.
        Call GetCommState to get the current state and use this to set
        the appropriate termios struct values.
	* termios.cc: reformat
	(tcsendbreak): implement -- add duration arg,
	call fhandler tcsendbreak as appropriate
	(tcdrain): implement -- call fhandler tcdrain as appropriate
	(tcflow): implement -- call fhandler tcflow as appropriate
	* fhandler.h: add new tc* protos
	* include/sys/termios.h: correct values of iflag bits,
	define CRTSXOFF and CRTSCTS, CBAUD, B57600 and B115200.
	Add protos for tc* functions.

Wed Nov 26 17:06:17 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* spawn.cc (perhaps_suffix): resolve symlinks to .exes.

Mon Nov 24 17:10:49 1997  Geoffrey Noer  <noer@cygnus.com>

	* cygwin.din: remove crypt
	* syscalls.cc (crypt): remove crypt stub

Sun Nov 23 17:34:42 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* spawn.cc (spawn_guts): save the path of the script itself,
	use the saved path while building the command line to execute.

Thu Nov 20 22:58:23 1997  Geoffrey Noer  <noer@cygnus.com>

	* stubs.cc: delete file, move unimplemented stubs to the
	files in which they would normally belong.
	* grp.cc (setgrent): implement (was in stubs.cc)
	* syscalls.cc: move regfree, mknod, setgid, set(e)uid, sync,
	crypt, and PPC __chkstk/_alloca/dll_entry stubs here from stubs.cc
	(sync): just return zero for now instead of -1
	(crypt): return -1 instead of 0

Thu Nov 20 22:41:57 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
        * spawn.cc (spawn_guts): A premature close of the spawned filehandle    
        was possible when reparenting an exited process.  Fix this.
        * dcrt0.cc (do_exit): Only do minimal cleanup if "pid focus"
        has moved to another windows process or the other process will
        become confused.

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* sigproc.cc (getsem): set errno to EPERM if existing semaphore
	cannot be opened.
	(wait_subproc): allow access to signal semaphores to process's
	owner only except for SIGCHLD (needed for SIGCHLD delivery after
	sexecXX calls).

Thu Nov 20 00:52:58 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* syscalls.cc (hash_path_name): Ignore trailing backslash when
        calculating pathname hash.
        * hinfo.cc (hinfo_vec::de_linearize_fd_array): Set use_tty
        if /dev/ttyn is detected in the shared_fd_table.  Before this
	change, executing "set CYGWIN_TTY=1", "bash", "unset CYGWIN_TTY",
	"/bin/pwd" would result in pwd printing nothing because
	the de_linearize code would use the wrong fhandler_xxx when
	reading from the buffer inherited from the parent process.
        * cygwin.din: Add new ctermid function for export.
        * syscalls.cc (ctermid): New function
	* exceptions.cc (call_handler): If called during a P_OVERLAY
	spawn, merely set appropriate flags and return.  The spawn
	code will then clean up and exit.
	* sigproc.cc (proc_exists): Reorganize to better detect defunct
	processes.  Don't clean up pinfo if process has a parent since the
	parent should clean up eventually.
	* spawn.cc: New global exec_exit.  Set by signal handler to
	value which should be used on exit from aborted spawn.
	(spawn_guts): Try harder to let the child terminate (if it is
	going to) before exiting on a signal.  Remove obsolete code.

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* exec.cc (file_exists): Removed
	* spawn.cc (spawn_guts): call perhaps_suffix to convert filename
	to win32 form and to check file existance; prog variable
	removed, all references changed to real_path variable.
	Do not inherit parent's window station/desktop on sexecXX calls.
	They are no longer needed with the new signal handling.
	(_spawnve): extra file existance check removed
	* winsup.h: file_exists prototype removed

Wed Nov 19 16:23:47 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* cygwin.din: add missing exports for random -- initstate
	and setstate (accessed by gawk among others?)

Tue Nov 18 22:27:10 1997  Geoffrey Noer  <noer@cygnus.com>

	* Makefile.in: Add spaces after colons in rules for make

Mon Nov 17 22:35:25 1997  Geoffrey Noer  <noer@cygnus.com>

        patch from proven@cygnus.com (Chris Provenzano):
        * Makefile.in: set SHELL = @SHELL@, set VPATH to only @srcdir@.
	Remove mingw from directories to build for now, adapt rules
	for building sysdef files without fancy VPATH
        * configure: regenerate
	* config/i386/makefrag: add rules to build setjmp/longjmp
	* regexp/Makefile.in: set SHELL = @SHELL@
	* regexp/configure: regenerate
	* utils/Makefile.in: set SHELL = @SHELL@
	* utils/configure: regenerate

Mon Nov 17 18:36:50 1997  Geoffrey Noer  <noer@rtl.cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* fhandler.cc (fhandler_disk_file::open): calls to symlink_XXX
	replaced with path_conv class calls.
	* path.cc (path_conv::path_conv): comments added, O_NOSYMLINK case
	added.
	* path.h (class path_conv): symlink_p, exec_p - new class members.
	* spawn.cc (spawn_guts): call path_conv instead of symlink_follow.

Sun Nov 16 15:54:27 1997  Geoffrey Noer  <noer@rtl.cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* dcrt0.cc (do_exit): Use new pinfo element in debug statement.
	* pinfo.cc (pinfo_init): Eliminate use of "PID" environment
	variable in favor of scanning the process table for a
	SpawnedProcessId field matching current windows process id.
	Should speed up spawned process startup slightly.  Delay setting
	of dwProcessId until process is capable of processing signals
	since this field is used to build signal semaphores.
	* signal.cc (kill_worker): Perform a `proc_exists' on the pid
	in question if signal == 0.  This will verify that the process
	actually exists and was not abnormally terminated.
	* sigproc.cc (sigproc_init): Initialize dwProcessId field after
	signal processing has been initialized.
	(sigproc_terminate): Remove events[0] close.
	(getsem): Use GetCurrentProcessId to find the windows pid since
	this dwProcessId field is not yet set up.  Use proc_exists to
	determine if error should be printed on OpenSemaphore error.
	(proc_exists): New function.  Makes more exhaustive test of
	process existence.  Determines if process died without going
	through normal shutdown.
	(wait_subproc): Close wakeup event only on thread exit.
	* spawn.cc: Remove pExeced.  Use new field in pinfo.
	(spawn_guts): Initialize dwSpawnedProcessId field.
	* utils/ps.cc (main): Perform a kill(pid, 0) on any pids that
	appear to be active.  This will clear out pids that have died
	abnormally.  'ps -f' bypasses this.
	* winsup.h (class pinfo): Add dwSpawnedProcessId field.

Sun Nov 16 15:54:27 1997  Geoffrey Noer  <noer@rtl.cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* pinfo.cc ((pinfo_init): use dwProcessId for execed/spawned
	check, set subproc_ready event only if the process is exec'ed.
	* spawn.cc (spawn_guts): initialize hProcess and dwProcessId
	fields of pinfo on exec, keep progname field on spawn.

Sun Nov 16 15:54:27 1997  Geoffrey Noer  <noer@rtl.cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* dcrt0.cc: remove commented out code
	* spawn.cc: fix misapplied patch problem

Sun Nov 16 15:54:27 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* fhandler.cc (fhandler_dev_null::open): Open Windows 'nul'
	device rather than "faking" a real open.
	(fhandler_dev_null::close): delete.
	(fhandler_dev_null::fstat): delete.
	(fhandler_dev_null::ioctl): delete.
	(fhandler_dev_null::read): delete.
	(fhandler_dev_null::write): delete.
	(fhandler_dev_null::lseek): delete.
	(fhandler_dev_null::dup): delete.
	* fhandler.h (class fhandler_base): delete above methods from
	class.
	* hinfo.cc (hinfo_vec::build_fhandler): Use new fhandler_dev_null
	class which opens 'nul' device.  Treat /dev/null similarly to
	other Windows devices.  This allows redirection of /dev/null to
	non-cygwin processes.

Sun Nov 16 15:54:27 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* dcrt0.cc (do_exit): Use EXIT_* flags to determine how exit
	should proceed.  Honor new EXIT_NOCLOSEALL to avoid
	close_all_files.
	* exceptions.cc (__cygwin32_exception_handler): Use new
	EXIT_SIGNAL define to indicate exiting due to signal.
	* signal.cc (sigprocmask): Slightly more defensive check against
	being called prior to complete cygwin setup.
	(_raise): Defensive check to guard against being called prior to
	complete cygwin setup.
	* sigproc.cc (stopped_or_terminated): Use new EXIT_SIGNAL define
	to detect exiting due to signal.
	* sigproc.h: Define flags to be used during exit process as
	EXIT_*.
	* spawn.cc (spawn_guts): Use EXIT_* constants to control how
	do_exit proceeds after _P_OVERLAY.

Sun Nov 16 15:54:27 1997  Geoffrey Noer  <noer@cygnus.com>

	* sysconf.cc (sysconf): return 1048576 for ARG_MAX until
	we figure out the right value (_POSIX_ARG_MAX is only 4K
	which is too small).

Sun Nov 16 15:54:27 1997  Geoffrey Noer  <noer@cygnus.com>

        patch from sos@prospect.com.ru (Sergey Okhapkin):
        * dcrt0.cc (dll_crt0_1): call winsock_init if neccesary.
        * fhandler.cc ((fhandler_socket::fhandler_socket): moved to net.cc
        * fhandler.h (class fhandler_socket): destructor prototype added.
        * fork.cc (cygwin_fork_helper1): set PID_SOCKETS_USED in the
        child's pinfo if parent has open socket descriptors; call
        winsock_init in child code if necessary.
        * net.cc: static variable winsock_init_p removed;
        number_of_sockets is new global variable containing number of
        opened sockets.
        (winsock_init): made global, save "winsock inited" flag in process
        state field.
        (cygwin32_winsock calls): condition for winsock initialisation
        changed
        (fhandler_socket::fhandler_socket): new, moved from fhandler.cc;
        increment number_of_sockets on constructor call.
        (fhandler_socket::~fhandler_socket): new.  Decrement
        number_of_sockets on destructor call, check for negative value.
        (fhandler_socket::ioctl): check for winsock initialisation added.
        * spawn.cc (spawn_guts): handle PID_SOCKETS_USED in child's pinfo.
        * winsup.h: PID_SOCKETS_USED - new enum value; number_of_sockets
	and winsock_init() prototypes added.

Wed Nov 12 23:02:34 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
        * exceptions.cc: Substitute do_exit for _exit as appropriate.
        do_exit allows full 32 bits of exit value.  The upper 16 bits
        are used for special cygwin operations.
        * winsup.h: Change definition of do_exit to allow calling from
        signal handler.
        * dcrt0.cc (do_exit): Change to allow calling from signal handler
        in place of _exit.  This is necessary to ensure that only cygwin
        internal applications can exit with the upper order 16 bits set
        to non-zero.

Wed Nov 12 23:02:34 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
        * dcrt0.cc (do_exit): New function.  Subsumes functionality of
	_exit but takes a DWORD argument.  Changed to avoid some shutdown
	activities when called with REPARENTING bit set in argument.  Also
	explicitly kills any executing non-cygwin subprocess from a
	spawn(P_OVERLAY)...
        (_exit): Use do_exit for exiting.  Ensure that only low order 1
        bits of status are used or confusion will result if exiting with
        some higher order bits set.
        * exceptions.cc (set_process_mask): Reflect new method for
	sig_send to send signals to self.
        (handle_sigsuspend): Reflect new method for sig_send to send
	signals to self.
        * fork.cc: A handle name was changed in the pinfo structure to
        be more reflective of its use.  Change forkee_stopped to
        subproc_ready everywhere.
        * pinfo.cc (pinfo::clearout): Change forkee_stopped to
	subproc_ready.
        (pinfo_init): Use PID_EXECED flag to determine if this process has
        been execed.  If so, signal the remaining stub in the process
	which invoked us so that the stub can terminate and let us take
	over as this pid.
        * sigproc.cc (sig_send): Change method for determining if sending
        signals to myself.  A NULL pointer means communicate with my
        signal handler.  This is necessary to allow communication with
        our own signal processors after reparenting an execed process.
        Also, add an additional test to detect if a process goes away in
        the middle of attempting to send it a signal.
        (allow_sig_dispatch): Reflect new method for sig_send to send
	signals to self.
        (getsem): Use dwProcessId in names for signal semaphores.  Allows
        communicating with both parts of a process that is temporarily
        "split in two" while execing.
        (sig_proc): Avoid printing an error if WAIT_FAILED and exiting
        anyway.  Process requests even if loop_wait == 0.
        (proc_subproc): Defensive check for manipulating processes prior
        to initialization or after terminating sigproc.
        Use different check for subprocesses that have been reparented.
        Hopefully this will eliminate WFSO, error 6 problems.
        (wait_subproc): Only exit when loop_wait == 0 and not dealing with
        a process.
        * spawn.cc: Set up two global variables, used on exit when
        execing a non-cygwin process: hExeced - handle of non-cygwin
	process which is being waited for by a stub, pExeced - windows pid
	of the process.
        (spawn_guts): Reorganize to always (temporarily) wait for the new
        process when P_OVERLAY.  If a cygwin process is invoked, then the
        wait will return when an event is signalled and the new process
	will be "reparented" in the ppid.  If a non-cygwin process is
	invoked, wait until the process exits or a signal is received
	which terminates the process.  In this case, the do_exit function
	will terminate the non-cygwin process.
        * winsup.h: Rename forkee_stopped to subproc_ready since this
	event now has a dual role which is better defined by this new
	name.  Add a new flag (PID_EXECED) for process_state.  Define a
	new function `do_exit' which operates similarly to _exit
        but takes > 16 quantities with the high order bit signifying
	different exit actions.

Mon Nov 10 17:11:08 1997  Geoffrey Noer  <noer@cygnus.com>

        * include/utime.h: remove (moved to newlib/libc/sys/cygwin32/sys)
        so as not to conflict with the one in newlib/libc/include.

Mon Nov 10 15:11:42 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* exceptions.cc (__cygwin32_exception_handler): exit with
	"core dumped" exit code after writing "core" file.

Mon Nov 10 15:11:42 1997  Geoffrey Noer  <noer@cygnus.com>

        patch from cgf@bbc.com (Chris Faylor):
        * console.cc: Add convenience macros and structures for handling
        scrolling.
        (fhandler_console::fillin_info): New function to fill in the `info'
        struct.
        (fhandler_console::scroll_screen): Change to scroll only the visible
        portion of the screen.  Honor scroll regions more stringently.
        (fhandler_console::open): Use new fillin_info function.
        (fhandler_console::ioctl): Use new fillin_info function which
        automatically calculates screen size.
        (fhandler_console::clear_screen): Use new fillin_info function.
        Only clear visible portion of screen.
        (fhandler_console::cursor_set): Add a flag to indicate whether
        cursor positioning is absolute within buffer or is screen relative.
        Use new fillin_info function to get screen information.
        (fhandler_console::cursor_rel): Use new fillin_info function.
        Change for new cursor_set parameter.
        (fhandler_console::cursor_get): Use new fillin_info function.
        (fhandler_console::char_command): Use new fillin_info function
        where appropriate.  Change for new cursor set parameter where
        appropriate.  Scroll only visible portion of screen when required.
        * fhandler.h (class fhandler_console): Add fillin_info, change
        cursor_set to reflect additional argument.

Mon Nov 10 15:11:42 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
        * dcrt0.cc (dll_crt0_1): Register process start time.
        * fork.cc (cygwin_fork_helper1): Register process start time.
        * utils/ps.cc (main): Report process start time.
        (start_time): New function to format time similarly to UNIX ps.
        A time from today shows as HH:MM, times from previous days just
        show the month and day.
        * winsup.h (class pinfo): Add start_time field.

Mon Nov 10 11:54:27 1997  Ian Lance Taylor  <ian@cygnus.com>

        * include/Windows32/Defines.h (TIME_ZONE_ID_INVALID): Define.
        * times.cc (gettimeofday): The error return from
        GetTimeZoneInformation is TIME_ZONE_ID_INVALID, not
        TIME_ZONE_ID_UNKNOWN.

Sun Nov  9 17:08:30 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* Makefile.in: add ../libiberty/strsignal.o
	* cygwin.din: add exports for strsignal, strtosigno
	* utils/kill.cc: changes to allow accepting signal name
	as argument

Sun Nov  9 17:08:30 1997  Geoffrey Noer  <noer@cygnus.com>

	* include/limits.h: define PATH_MAX here instead of
	include/sys/param.h, define _POSIX_NGROUPS_MAX as 0 not 1
	(system invariant value, not implementation-specific)
	* include/sys/param.h: remove PATH_MAX, change NOFILE from 64
	to 8192, delete PATHSIZE, remove safety wrapper around
	MAXHOSTNAMELEN, add comments
	* sysconf.cc (sysconf): return NGROUPS_MAX not zero,
	return _POSIX_SAVED_IDS not zero.  Return _POSIX_CHILD_MAX
	not 4096.  Return _POSIX_CHILD_MAX, not 8.

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* winsup.h: add proto for setdtablesize, define NOFILE_INIT
	and NOFILE_INCR
	* hinfo.cc (hmap_init, hinfo_vec::find_unused_handle): change to
	support virtually unlimited numbers of fds.  Remove setdtablesize
	proto
	* syscalls.cc: initialize dtable_size to NOFILE_INIT instead of
	NOFILE

Thu Nov  6 13:14:09 1997  Geoffrey Noer  <noer@cygnus.com>

	* exceptions.cc (__cygwin32_exception_handler): don't
	print "In cygwin32_except_handler" for exceptions Cygwin32
	isn't going to handle.  Print "(progname PID) Exception: <type>"
	to console.  Redirect all detailed information including the
	stack trace to <progname>.core.  This should reduce confusion
	about what's causing the exception (a lot of people would see "In
	cygwin32..." and think the problem was in Cygwin32 when most of
	the time it was in some other program).
	* syscalls.cc: add fixme
	* times.cc: add fixme

Wed Nov  5 19:23:10 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* Makefile.in: force .c.os and .cc.os to be built in same
	directories as source

Wed Nov  5 19:23:10 1997  Geoffrey Noer  <noer@cygnus.com>

	* drct0.cc (dll_crt0_1): stop initializing winsock on process
	startup since that slows down startup time of all processes, even
	ones that don't end up making Winsock calls.
	* fork.cc (cygwin_fork_helper1): don't need to call uinfo_init
	or socket_checkinit after fork -- the appropriate functions will
	do the necessary initialization if they are ever called.
	* net.cc: init winsock_init_p to zero and make it static
	(all exported functions): call winsock_init before making
	any WinSock calls since this no longer happens in dcrt0.cc
	startup code.  Only do this if !winsock_init_p.
	(winsock_init): checkinit renamed.  Now just inits winsock
	without checking whether it has been already initialized.
	Make it static.
	* uinfo.cc (uinfo_init): after we call getpwnam, we know
	the passwd file has been read in so don't check initialization
	of it.  However, we do need to read_etc_group() if group_in_memory
	isn't set.
	* passwd.cc: rename global i variable to pw_pos, rename
	passwd_in_memory to passwd_in_memory_p to match net.cc scheme.
	Add comments.
	(read_etc_passwd): make static
	(various): make sure to read_etc_passwd() if passwd_in_memory
	isn't set
	* grp.cc: add comments, rename idx global to grp_pos,
	rename group_in_memory to group_in_memory_p to match net.cc
	scheme, group_in_memory_p no longer static (needs to be accessed
	by uinfo_init)
	* winsup.h: remove proto for socket_checkinit since that's
	renamed and static within net.cc

Tue Nov  4 01:02:20 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* signal.cc (sigprocmask): Newer versions of gcc will call
	sigprocmask when a builtin constructor is activated.  If this
	happens prior to the setup of u->self, then a NULL dereference
	will occur.  Guard against this.

Mon Nov  3 17:00:45 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* hinfo.cc (hinfo_vec::build_fhandler): Open a console for
	/dev/tty when !use_tty.

Thu Oct 30 10:28:15 1997  Tom Tromey  <tromey@cygnus.com>

        * include/mapi.h: New file.
        * sysdef/i386/mapi32.def (MAPISendMail@20): New export.

Thu Oct 30 15:08:13 1997  Geoffrey Noer  <noer@cygnus.com>

        * times.cc: add comments listing standards funcs are defined in
	(dump_filetime): remove unused local func
        * net.cc (fail): remove local func, replace one reference with
        equivalent debug_printf, add standards comments, reformat a little
        (fhandler_socket::close): simplify handling of res
        (fhandler_socket::fstat): set ENOSYS (unimplemented)
        * stubs.cc: set ENOSYS in unimplemented funcs
        * uname.cc: add standards comment
	* ntea.cc: reformat

Wed Oct 29 22:43:57 1997  Geoffrey Noer  <noer@cygnus.com>

	* times.cc (settimeofday): set ENOSYS instead of EPERM
	since ENOSYS maps to "Function not implemented" which is the
	case here.
	* syscalls.cc (seterrno): on failure, set EACCES instead of EPERM
	which is better for the unknown error case

Fri Oct 24 01:24:07 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from green@cygnus.com (Anthony Green):
	* dcrt0.cc: new host_dependent_constants object with a global
	instance of it which allows constants that are different in Win 95
	and NT to be saved here instead of having forks in the code and
	having to check the OS type each time.  Add two constants for
	fhandler, one for sharing attributes and one for upper word value
	for locking files.
	(dll_crt0_1): call host_dependent init function
	* fhandler.cc (fhandler_base::open): use above object for
	setting shared attributes
	(fhandler_disk_file::lock): get upper word for locking from
	host_dependent_constants
	* winsup.h: define host_dependent_constants class and add extern
	for global instance of it

Wed Oct 22 02:27:53 1997  Geoffrey Noer  <noer@cygnus.com>

	of cygwin32_ wrappers
	* dcrt0.cc: External variable environ removed
	(dll_crt0_1): strip executable's path on console title if
	environment variable CYGWIN_TITLE set to "strip", references to
	environ removed.
	* environ.cc: New file. Code derived from newlib sources.
	* exec.cc: include stdlib.h
	(execl, execv): new (derived from newlib sources).
	(sexecve): reference to environ removed.
	(sexecvpe): call getenv instead of cygwin32_getenv.
	* grp.cc: new static variable group_in_memory
	(read_etc_group): skip blank lines
	(getgrgid, getgrnam, getgrent): call read_etc_group when necessary.
	* misc.cc (cygwin32_getenv/putenv/setenv/unsetenv): remove
	wrappers.
	* passwd.cc: new static variable passwd_in_memory
	(read_etc_passwd): skip blank lines
	(search_for, getpwent): call read_etc_passwd when necessary.
	(setpwent): fixed incorrect initialization of i var.
	* pinfo.cc (pinfo_init): initialize uid with illegal value to
	force read of /etc/passwd and /etc/group.
	* spawn.cc: call getenv instead cygwin32_getenv
	(spawn_guts): force read of /etc/passwd and /etc/group on sexec
	calls.
	* uinfo.cc (uinfo_init): read /etc/passwd and /etc/group only if
	uid is undefined.
	* winsup.h: remove protos for environ, cygwin32_getenv,
	cygwin32_putenv

Wed Oct 22 02:08:54 1997  Geoffrey Noer  <noer@cygnus.com>

	* utils/aclocal.m4: new file.  Define autoconf macros for
	determining whether we're compiling for the cygwin32 environment
	or not and determine the executable suffix
	* utils/configure.in: call AM_CYGWIN32 and AM_EXEEXT
	* utils/configure: regenerate
	* utils/Makefile.in: add $(exeext) after executable names so
	programs will be built with the .exe suffix

Wed Oct 22 00:50:27 1997  Geoffrey Noer  <noer@cygnus.com>

	Now that it is possible to use gdb using a stable
	cygwin.dll to debug a program using a newer, potentially buggy
	cygwin.dll, the strace mechanism will probably end up being
	used more and more for debugging timing/race-condition bugs that
	aren't easily exposed in a gdb session.  The following changes
	make the strace facility better for debugging timing issues by
	storing the last few commands in a buffer instead of writing
	to disk each function call.

	patch from cgf@bbc.com (Chris Faylor):
	* dcrt0.cc (dll_crt0_1): Change to strace_init call to take
        an argument (for planned future registry changes).
        (_exit): Call strace_dump when appropriate.  Add a debugging
	printf.
        * include/sys/strace.h: Add _STRACE_CACHE, _STRACE_EXITDUMP,
	strace_dump ().
        * strace.c (strace_init): Allow hexadecimal, octal setting of
        strace flags in environment variable.  Handle new cache option.
        (strace_printf): Display number of seconds from last message.
        Handle _STRACE_CACHE.
        (strace_dump): New function.  Dump cached messages to disk.

Wed Oct 22 00:08:40 1997  Geoffrey Noer  <noer@cygnus.com>

	* cygwin.din: export socket calls without cygwin32_ prefix
	* net.cc: remove unused herror function in favor of
	cygwin32_herror	which is exported as herror
	* include/netdb.h: we are now exporting the socket calls without
	the cygwin32_ prefix so we don't need the nasty remapping in
	header files
	* include/arpa/inet.h: ditto
	* include/sys/socket.h: ditto
	* select.cc (select): make extern C

Tue Oct 21 22:52:29 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* sigproc.cc (sigproc_terminate): Fix flawed attempt to signal
        any processes waiting for signal notification success when the
        process receiving the signal is terminating.
        (wait_subproc): Report on errors when opening the
	sync_proc_subproc mutex.  Move initialization of events[0]
	"wakeup" signal prior to wait_subproc_inited or risk a (miniscule)
	chance for a reference to a NULL handle.
        * strace.cc (ta[]): Change WM_ASYNCIO entry to reflect previous
        changes to WM_ASYNCIO constant.

Tue Oct 21 14:30:14 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):

Mon Oct 20 20:16:47 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* window.cc (alarm): When there is a previous alarm() request
	with less than one second remaining, then the return from a call
	to alarm() is supposed to return 1.

	(ctrl_c_handler): Use _raise to invoke the correct signal.
	(sighandle): New function.  Subsumes most of ctrl_c_handler.

	hwnd of hidden window.
	* pinfo.cc: Add new sigproc.h include.
	(pinfo::clearout): Use process_state field in pinfo (replaces

	* utils/ps.cc (main): Use new pinfo process_state field (replaces
	inuse_p).  Detect "zombie" processes similarly to UNIX ps.
	* wait.cc: Add required includes.
	(wait_found): Function obsoleted by new sigproc handling.
	(wait4): Reorganize to use new sigproc handling.
	* window.cc: Changes for new sigproc handling.
	(WndProc): Remove SIGNAL handling obsoleted by new sigproc
	handling.  Use static window handle since the field has been
	removed from pinfo.  Use _raise where appropriate to send signals.
	(Winmain): Replace global window handle with static since the
	field has been removed from pinfo.
	(window_init): Remove obsolete function.
	(gethwnd): New function to allocate hidden window on demand rather
	than at startup.
	(window_terminate): Kill hidden window only if allocated.
	(setitimer): Use gethwnd function to retrieve hidden window
	handle.
	* winsup.h: Remove stuff made obsolete by sigproc handling.  Move
	some constants to new sigproc.h header file.  Remove inuse_p,
	cygin_parent_p, split_heap_p.  Replace with a single process_state
	field.  Define bit fields for process_state in an enum for easier
	debugging.

Mon Oct 20 19:17:33 1997  Geoffrey Noer  <noer@cygnus.com>

	* sysdef/i386/winserve.def: remove ancient version of cygwin.din
	* include/sgtty.h: remove since Cygwin32's tty handling doesn't
	support bsd syntax/semantics
	* include/sys/termios.h: change winsize struct to include
	ws_xpixel and ws_ypixel members
	* cygwin.din: remove export of ScreenCols, ScreenGetCursor,
	ScreenRows, ScreenSetCursor, get_pid__5pinfo, getkey, _getkey,
	kbhit, _kbhit, __small_printf = small_printf__FPCce
	* key.cc: remove.  Similar functionality exists in ncurses
	which can be compiled for Cygwin32

	ScreenRows): delete and delete SCREEN_ROWS/COLS defines
	* pold.c: remove old pipe-related code that's no longer used
	* include/regex.h: remove, it's not a part of cygwin.dll
	* syscalls.cc: started to add comments including standards
	information
	(truncate): new
	(ftruncate): length is an off_t, not a size_t.  Add missing 
	return value to debug printf
	* syscalls.h: ftruncate length is an off_t, add proto for truncate

        patch from cgf@bbc.com (Chris Faylor):
	* console.cc (fhandler_console::write): Recognize '@' as a valid
	character to follow a '\e[' sequence or get 'Bad escape' errors.

Wed Oct 15 18:44:25 1997  Geoffrey Noer  <noer@cygnus.com>

	* cygwin.din: restore __main as an export

Mon Oct 13 18:41:09 1997  Geoffrey Noer  <noer@cygnus.com>

	* cygwin.din: revert renaming of __assert since that's
	actually what it's supposed to be called
	* assert.cc: ditto

Fri Oct 10 19:25:49 1997  Tom Tromey  <tromey@cygnus.com>

        * include/Windows32/Base.h: Moved typedefs of CHAR, SHORT, etc,
        before all other uses in file.

Fri Oct 10 17:50:12 1997  Ian Lance Taylor  <ian@cygnus.com>

        * include/Windows32/Base.h: Only typedef CHAR, SHORT, and LONG if
        VOID is not defined

Thu Oct  9 00:46:40 1997  Geoffrey Noer  <noer@cygnus.com>

	* cygwin.din: remove all libgcc.a exports.  They don't
	belong here since libgcc.a doesn't really relate to the
	purpose of cygwin.dll, and (to make things worse) the contents
	change over time.
	* assert.cc: rename __assert to __cygwin32_assert
	* exceptions.cc: rename __stack_trace to __cygwin32_stack_trace,
	__cygwin_except_handler to __cygwin32_except_handler

Tue Oct  7 12:52:25 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* dcrt0.cc (_exit): under Win 95, don't send SIGCHLD
	unless special env variable is set.  This works around a
	problem where exiting a process can hang under Win 95.

Mon Oct  6 23:41:34 1997  Geoffrey Noer  <noer@cygnus.com>

	* regexp: new directory containing free regexp code by
	Henry Spencer.  Taken from the most recent release of NetBSD.
	Write configure.in and Makefile.in, based on files from
	winsup/utils.
	* Makefile.in: build regexp directory and include objs in
	cygwin.dll.
	* stubs.cc: remove all reg* stubs except for regfree which
	isn't provided by above code.

Mon Oct  6 13:35:48 1997  Geoffrey Noer  <noer@cygnus.com>

	* dcrt0.cc: remove asm idata3 terminator, now that ld is fixed
	such that this is no longer necessary.
	* libccrt0.cc: ditto

Mon Oct  6 13:14:00 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* spawn.cc (spawn_guts): return child's PID on
	spawn (_P_NOWAIT,...) instead of child's handle.
	(cwait): rewritten as a wrapper to waitpid.

Mon Oct  6 13:02:01 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* net.cc (socketpair): new
	* cygwin.din: add socketpair export

Mon Oct  6 13:01:51 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* dcrt0.cc: Remove obsolete call to fork_terminate.
        * exceptions.cc: Respace, remove extraneous trailing whitespace.
        Change critical section to mutex since there are supposedly
        multi-processor problems with critical sections under NT.
        Use "lock_cs" and "unlock_cs" macros to lock/unlock critical
	regions.
        (init_exceptions): Change critical section initialization to mutex
        initialization.
        (set_process_mask): Use locking macros to control access to
	sig_mask.
        (ctrl_c_handler): Use lock_cs/unlock_cs to control access.
        (events_init): Use standard cygname function to create names for
        shareable objects.
        (events_init): Close cs mutex.
        * fork.cc: Use event flags which are specific to the child being
        forked.  This prevents one process from prematurely activating
        another.  It also makes fork slightly more thread-safe.
        (fork_init): Remove event initialization.
        (fork_terminate): Remove function.
        (cygwin_fork_helper1): Initialize events on a per-fork basis.
        Events are inherited in child's pinfo structure.
        Remove child->hThread initialization as it not needed.  Use
        pi.hThread where child->hThread is used.
        Work around Windows 95 bug where a WaitForSingleObjects will
        sometimes return ERROR_INVALID_HANDLE when it is resumed after
        a suspend.
        * pinfo.cc: Remove references to hThread field whereever it occurs.
        * strace.cc: Use standard cygname function to create name for
        strace_mutex.  Prevents confusion between different .dll versions.
        * wait.cc (wait_found): Remove reference to hThread.
        * winsup.h (class pinfo): Remove reference to hThread.  Add
        per-process fork control event handles.
	* include/limits.h:  Increase NGROUPS_MAX from 0 to 1 to reflect
	recent change to getgroups.

Mon Oct  6 11:06:22 1997  Geoffrey Noer  <noer@cygnus.com>

	Oops.  ../libio refers to objdir and is not the same
	as $(srcdir)/../libio.

Thu Oct  2 23:12:19 1997  Geoffrey Noer  <noer@cygnus.com>

	Revert patches to sources applied after Sept 16.  Removed
	relevant portions of ChangeLog entries.  Some of those changes
	may reappear later (removing the entries makes this log easier
	to understand).

Thu Oct  2 15:34:03 1997  Geoffrey Noer  <noer@cygnus.com>

	* Makefile.in: remove hardcoding of SHELL to /bin/sh, remove
	../libio from INCLUDES since $(srcdir)/../libio is already
	included.
	* glob/Makefile.in: remove hardcoding of SHELL to /bin/sh

Mon Sep 29 14:06:24 1997  Geoffrey Noer  <noer@cygnus.com>

	behavior.

Thu Sep 25 18:35:49 1997  Geoffrey Noer  <noer@cygnus.com>

	* Makefile.in: remove debugdll defs since the shared memory
	overlap problem is solved by the timestamp addition of Sept 23
	* version.h: rework explanations of version numbers

Thu Sep 25 16:21:49 1997  Geoffrey Noer  <noer@cygnus.com>

	* spawn.cc: add missing cast to debug printf

Thu Sep 25 16:14:17 1997  Ian Lance Taylor  <ian@cygnus.com>

        * path.cc (conv_to_win32_path): Call backslashify on a win32
        path.

Tue Sep 23 17:58:17 1997  Geoffrey Noer  <noer@cygnus.com>

	Fixes for things that were causing compile-time warnings:
	* exec.cc (_execve): add missing const to args to match def
	of execve in newlib which this calls.
	(sexecve): add missing const to def
	(sexeclpe): don't need to cast argv in sexecvpe call
	(sexecvpe): add missing const to def
	* winsup.h: correct _execve proto, add protos for login/logout

	for C++
	* init.cc: respacing

Tue Sep 23 17:05:50 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* dcrt0.cc (dll_crt0_1): don't use alloca for allocating storage
	for environment blocks because setenv() uses realloc!

Tue Sep 23 17:05:50 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from cgf@bbc.com (Chris Faylor):
	* Makefile.in (LD_STUFF): Add datestamp.o after DLL_OFILES.
        (datestamp.o): New target.  datestamp.c is generated whenever .o
        files change.  It creates a file containing a "date stamp"
        which is used by the function "cygname" to create named
	shared memory, events, mutexes, and semaphores used by
	cygwin.dll.  The unique datestamp allows multiple loading of
	different cygwin.dll's even when they have incompatible use
	of shared memory areas.
	* init.cc (dll_entry): Create the name string used by cygname
        from the name of the invoking .dll + the datestamp of the
        .dll from the auto-generated datestamp.c
        * misc.cc (cygname): New function.  Creates a standard Cygnus
        shared resource name given a prefix, a name (e.g., pinfo_mutex),
        and a numeric suffix (e.g., a pid).  Replaces custom code in
        several files.  Uses cygwin_dlldate from datestamp.c to construct
        names that are unique for a given cygwin load.
        * shared.cc (open_shared_file_map): Use standard cygname function
        to create names for sharable objects.  Use static handle 'h'
        so that it can be closed later by shared_terminate.
        (shared_terminate): Guard against calling CloseHandle with a
        NULL handle.
        (create_shared_fd_mapping_name): Use cygname function to generate
        the name for the "fd_map".

Tue Sep 16 23:34:36 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* fcntl.cc (_fcntl): correct errno value (EBADF instead of
	EBADFD).

Tue Sep 16 17:22:28 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* include/Windows32/Defines.h: add missing defines needed
	for NTEA usage.
	* ntea.cc: remove them from here

	* pinfo.cc (pinfo_init): Fix a NULL pointer dereference when PID
	environment variable contains garbage.

Thu Sep 11 16:51:40 1997  Geoffrey Noer  <noer@cygnus.com>

	* syscalls.cc (ftruncate): read file pointer location at
	beginning of function and restore it at the end

Thu Sep 11 15:35:10 1997  Ian Lance Taylor  <ian@cygnus.com>

        * path.cc (backslashify): Don't turn a single trailing slash into
        a double trailing slash.

Wed Sep 10 11:40:55 1997  Ian Lance Taylor  <ian@cygnus.com>

        * include/Windows32/Structures.h: Add PACKED to PRINTDLG.
        * include/Windows32/Functions.h: Add STDCALL to a few function
        declarations.

Tue Sep  9 02:12:18 1997  Geoffrey Noer  <noer@cygnus.com>

	patch from sos@prospect.com.ru (Sergey Okhapkin):
	* syscalls.cc (_link): Implement hard links under NT with NTFS
	using the backup API.  Default to copying the file (what we did
	before).

	CreateProcess.
        * exceptions.cc (exit_already): New file static variable.
        (__cygwin_exception_handler): If exit_already is set, just
        return.  If we get an exception we don't recognize, let the next
        exception handler handle it.  Just ignore the INVALID_HANDLE
        exception.
        (really_exit): Remove file static exit_already variable; use the
        global one.
        (events_terminate): Set exit_already.

Wed Sep  3 12:44:45 1997  Geoffrey Noer  <noer@cygnus.com>

	* Makefile.in: split subdir_do into subdir_dobefore and
	subdir_doafter to reflect whether the subdir in question
	should be built before or after the top level is built
	(e.g. glob needs to be built before libcygwin.a but libcygwin.a
	needs to be built before utils).

Thu Aug 28 12:09:39 1997  Geoffrey Noer  <noer@cygnus.com>

	* configure.in: when setting up EXE_LDFLAGS, correct the
	location of crt0.o to ../../newlib since EXE_LDFLAGS is used
	by Cygwin32 subdirectories where newlib is two directories up
	instead of one.
	* configure: regenerate with autoconf

Thu Aug 28 00:13:11 1997  Geoffrey Noer  <noer@cygnus.com>

	test.exe build rule.

Wed Aug 20 14:45:17 1997  Geoffrey Noer  <noer@cygnus.com>

	* Makefile.in: link cygwin.dll with -lm -lgcc -lc -lgcc instead
	of -lc -lm -lm -lgcc so lgcc finds abort().  Add definitions that
	will eventually be used to build a cygwindebug.dll used by gdb
	so gdb can debug a buggy cygwin.dll.  Change some variable names
	to have underscores in them (DLL_NAME, LIB_NAME, DEF_FILE, etc.).
	Comment out text.exe build rule. 

Tue Aug 19 20:41:51 1997  Geoffrey Noer  <noer@cygnus.com>

	in the right order.  All modifications of console title are
	mutexed to allow tty code to obtain console window handle right.
	* exceptions.cc (exception_init): initialization of signal_arrived
	event moved to events_init().
	(call_handler): raise signal arrived event after resuming main
	thread.
	(__cygwin_exception_handler): raise signal instead of calling
	ctrl_c_handler, because exception handler is called in a context
	of the thread, caused exception, and SuspendThread in call_handler
	blocks itself :-)
	(ctrl_c_handler): clear stopsig on SIGCONT delivery, call
	ResumeThread until suspend count > 1, notify parent about child's
	status changed.  Care about handling SIGCONT signal. On stop
	signals release vital mutexes used by stopped thread, save
	signal number for wait(WUNTRACED) calls, notify parent about child's
	status change.  Do not stop processes running without job control
	(when pgid == 0).  Ensure that main thread is unblocked before
	call _exit().
	(events_init): new
	(events_terminate): new
	* fcntl.cc (_fcntl): use saved open flags on F_GETFL/F_SETFL instead
	of game with access_ variable.  Is this variable longer needed?

	openflags_ variable.
	(fhandler_base::open): save file open flags.
	* fhandler.h (fhandler_base): new openflags_ member, new member

	new classes fhandler_tty_slave, fhandler_pty_master,
	fhandler_tty_master
	* fork.cc (cygwin_fork_helper1): inherit control tty number on fork,
	call tty_init on child startup.
	* hinfo.cc: include stdlib.h and ctype.h.
	(hmap_init): take care on exec'ed processes.
	(init_std_file_from_handle): open /dev/tty for standard handles if
	tty usage enabled.
	(build_fhandler): check for tty slave and pty master devices.
	* include/exceptions.h: exception handler returns "int" (exception
	handling code), not "void".
	* include/termios.h: new defines, struct winsize must contain
	ws_xpixel and ws_ypixel members (commented now to avoid
	incompabilities with existing binaries.  Should be uncommented in
	next release.
	* net.cc (gethostbyaddr): corrected return value
	* passwd.cc (parse): remove trailing newline from password
	lines (user's shell was reported with trailing newline before).
	* pinfo.cc (lock_pinfo_for_update): open mutex code moved to
	events_init() in exceptions.cc.
	(destroy_pinfo_lock): removed, pinfo_mutex is now closed in

	process).
	* select.cc: all debug_printf's changed to select_printf.
	(fd_pipe_map): new class to implement (polling...) select on pipes.
	(pipethread): new
	(cygwin32_select): comment out socket only case since generic
	code (select on different types of handles) works for sockets too
	but is interruptable.  The case for always_ready_used is used now
	and for polling select (zero timevalue).  Changes to support
	select on pipes.
	* shared.cc (shared_info::initialize): initialize tty table.
	* signal.cc (sleep/usleep/sigsuspend/pause): signal_arrived moved
	from u area to dll's address space, signal_arrived is manual reset
	event now.
	(_raise): implemented as kill (self, sig).
	(kill_worker): new.  Use SendMessage instead of PostMessage to avoid
	some timing problems.
	* spawn.cc: include tty.h.
	(spawn_guts) call close_all_files() on exec, call tty_terminate()
	before process exit.  Some changes due to moving signal_arrived to
	dll's address space.
	(_spawnve): inherit control tty number on spawn.
	* syscalls.cc (close_all_files): reenabled.  The code is ok after
	all! The troubles were due to incorrect usage on exec() calls.
	(setsid): no longer a stub
	(ptsname): new
	* termios.cc: all syscall_printf's changed to termios_printf.
	(tcget(set)pgrp): rewritten, no longer a stub.

	(tty_terminate): new
	(attach_tty): new

	of 0x80000000 instead of 0x8000000
