Hi all,

I've made a new winsup snapshot available.  This is *not* ready for
a general release but it's good to have the latest stuff in your
hands.  By my observations, Windows 9x seems to behave better for me
now but I get much worse behavior under NT.  *sigh*

Also please note that we still have some patches in the queue, in
particular a couple more from Corinna Vinschen.  Getting an update to
b20 that makes things stable again is our first priority but we'll
try to get to them soon...

ChangeLog entries since b20 follow.

Wed Nov 11 14:00:45 1998  DJ Delorie  <dj AT cygnus DOT com>

        * cygwin.din (getpwnam): remove duplicates

Tue Nov 10 18:27:09 1998  Geoffrey Noer  <noer AT cygnus DOT com>

Tue Nov 10 15:56:03 1998  Geoffrey Noer  <noer AT cygnus DOT com>

        patch from Gary V. Vaughan <gvaughan AT oranda DOT demon DOT co DOT uk>:
        * dlfcn.cc (dlopen): return an introspective handle to the
        current module if name arg is NULL.  The Single UNIX
        Specification, Version 2 has this as a requirement.

Mon Nov  9 16:29:27 1998  Geoffrey Noer  <noer AT cygnus DOT com>

        * errno.cc (strerror): all errnos in
        newlib/libc/include/sys/errno.h are now listed here.

Mon Nov  9 16:29:27 1998  Geoffrey Noer  <noer AT cygnus DOT com>

        * include/cygwin/version.h: up DLL version and API minor
        version to mark following change.

        patch from Mumit Khan <khan AT xraylith DOT wisc DOT edu>:
        * cygwin.din: add exports for some of the newlib bessel
        functions (j1, jn, y1, yn).

Mon Nov  9 15:10:06 1998  Geoffrey Noer  <noer AT cygnus DOT com>

        * syscalls.cc (_link): rewrite FIXME.

Mon Nov  9 14:51:03 1998  Geoffrey Noer  <noer AT cygnus DOT com>

        * errno.cc (strerror): add string for EDEADLOCK.

        patch from Corinna Vinschen <corinna DOT vinschen AT cityweb DOT de>:
        * errno.cc (errmap[]): add END_OF_MEDIA and additional Win32
        error codes.

Sun Nov  8 21:28:01 1998  Christopher Faylor <cgf AT cygnus DOT com>

        * fhandler.h: fhandler_pipe cannot be is_slow under
        Windows9[58].  There is no way to check for EOF on a pipe
        without performing a read on that system.
        * syscalls.cc (read_handler): Don't check for ready_for_read
        unless this is a "slow" device.
        * winsup.h: Reorganize to accomdate fhandler.h requirement
        for os_type.

Sat Nov  7 23:27:05 1998  Christopher Faylor <cgf AT cygnus DOT com>

        * fhandler.h (fhandler_console): Add a new function declaration.
        * fhandler_console.cc (fhandler_console::read1): New function
        renamed from console_read to allow use of class fields.
        Detect readahead situation when doing line buffering and
        buffer does not contain \n.
        (fhandler_console::read): Reflect function name change.
        * select.cc (cygwin_select): Changes for better handling
        of < 1000 usec timeouts.
        (select_stuff::wait): Perform a poll on timeout to
        set any fd's that may have become active.
        (peek_pipe): More debugging.  Honor write_ready if set.
        (peek_console): Can't always use WaitForSingleObject.
        Detect readahead conditions set in fhandler_console::read1.
        Honor write_ready if set.
        (peek_windows): Honor write_ready if set.
        * times.cc (__to_clock_t): Return clock_t value.
        (times): Add some debugging printfs.

Fri Nov  6 20:15:20 1998  Christopher Faylor <cgf AT cygnus DOT com>

        patch from Corinna Vinschen <corinna DOT vinschen AT cityweb DOT de>:
        * spawn.cc (spawn_guts): find_exec() argument mismatch
        resulted in inability to run !# scripts which did not
        begin with '/'.

Tue Nov  3 16:12:59 1998  Christopher Faylor <cgf AT cygnus DOT com>

        * exceptions.cc (handle_exceptions): Don't wait for signal
        completion.
        (ctrl_c_handler): Ditto.
        * fhandler.h (fhandler_*): Declare new ready_for_read functions.
        * select.cc: Reorganize all methods into a peek_*, a poll_*,
        and a fhandler_*::ready_for_read.  This is to allow the _read
        function to query the state of an fd without starting a thread.
        * signal.cc (kill_worker): If sending a signal from a non-main thread
        don't wait for completion.
        * sigproc.h (myself_nowait_nonmain): New define for use by sig_send.
        * sigproc.cc (sig_send): Honor myself_nowait_nonmain.  Don't wait
        if not in main thread.
        (__release_signal_mutex): Revert to calling ReleaseMutex only
        once or mutex is released prematurely.
        * syscalls.cc (read_handler): Use new ready_for_read method to
        determine if an fd has data for reading.  This function optionally
        blocks until there is data to read.
        (read_helper): Add debugging statement.
        (_read): Move signal_arrived reset to before sig_protect to avoid
        a race.  Force read_handler thread to longjmp back to read_handler
        function on signal.

Tue Nov  3 12:18:31 1998  DJ Delorie  <dj AT cygnus DOT com>

        * utils/cygcheck.cc (dump_sysinfo): Note when not finding a
        program (like cpp) on the path is a good thing.

Tue Nov  3 01:26:08 1998  Geoffrey Noer  <noer AT cygnus DOT com>

        patch from Kazuhiro Fujieda <fujieda AT jaist DOT ac DOT jp>:
        * environ.cc (environ_init): correct size arg to parse_options

Mon Nov  2 21:40:32 1998  Christopher Faylor <cgf AT cygnus DOT com>

        * regexp/regexp.c (regatom): Respond to compiler warning.

Mon Nov  2 21:36:48 1998  Christopher Faylor <cgf AT cygnus DOT com>

        * exceptions.cc (handle_exceptions): cygwin should not
        print exception information if the exception is trapped
        via signal().
        Also use consistent timings for lock_cs() throughout.

Mon Nov  2 16:46:28 1998  Geoffrey Noer  <noer AT cygnus DOT com>

        * Makefile.in: For now, also include newlib/libc/sys/cygwin.
        Eventually will stop including newlib/libc/sys/cygwin32.

Mon Nov  2 19:38:30 1998  Christopher Faylor <cgf AT cygnus DOT com>

        patch from Corinna Vinschen <corinna DOT vinschen AT cityweb DOT de>:
        * syscall.cc (gethostname): function deleted
        * net.cc (gethostname): new function 'gethostname' which
        first calls wsock32::gethostname and only if it fails,
        calls GetComputerNameA.
