Hi all,
Another snapshot is available in the usual place. Note that Windows
9x support still needs some work. I may hold B20 back until this is
resolved. (Patches welcome as always!) :-)
Following are the ChangeLog entries since the last snapshot.
Regards,
Geoffrey Noer

-----------------------> snip <------------------------------
Tue Sep 29 23:33:11 1998 Christopher Faylor <cgf AT cygnus DOT com>
* fhandler_tty.cc (fhandler_pty_master::close): Make sure
both sides of both pipes associated with a tty master are
closed or suffer handle leaks.
Tue Sep 29 16:55:00 1998 Geoffrey Noer <noer AT cygnus DOT com>
* path.cc (mount_info::init): remove default mounts for
raw devices
* utils/mount.cc (reset_mounts): ditto
(main, usage): new -f flag disables warning messages about
missing mount point directories. Two new flags, disabled for
now: -c will create missing mount point directory, -g will
select adding the mount point to the global registry location.
* include/sys/mount.h: add MOUNT_GLOBAL define, for future
use.
Tue Sep 29 14:20:30 1998 Christopher Faylor <cgf AT cygnus DOT com>
* exceptions.cc (exception): Use %p to denote some hex
values.
* winsup.h (read_info): Add jmp_buf to structure. Required
for syscalls.cc change below.
Mon Sep 28 19:36:41 1998 Syd Polk <spolk AT cygnus DOT com>
* include/{tchar.h, direct.h}: Added so that
tcl8.1a2 can be compiled with cygwin.
Mon Sep 28 19:36:41 1998 Christopher Faylor <cgf AT cygnus DOT com>
* syscalls.cc (thread_reset): Yet another method for
handling interruptible reads.
(_read): Use thread_reset to reset reads after a signal.
Sun Sep 27 21:11:46 1998 Christopher Faylor <cgf AT cygnus DOT com>
* cygwin.din: New alias for __cygwin32_stack_trace.
* debug.cc (find_handle): Avoid leaving function without
unlocking.
(newh): Ditto.
* exceptions.cc (__cygwin32_stack_trace): Rename to just
`stack'. Shortens stack trace output.
(exception): Use %p to distinguish register values.
* fhandler_console.cc (fhandler_console::init): Remove
debugging sig_protect.
* init.cc (dll_entry): Move definition to avoid a
compiler warning.
* path.cc (mount_info::conv_to_win32_path): Detect
case of root directory when setting win32 relative
path.
(mount): Remove obsolete label.
* syscalls.cc (thread_sync): New function for exiting
the read helper thread.
(_read): Use new method for exiting the read helper
thread.
Sun Sep 27 11:25:06 1998 Christopher Faylor <cgf AT cygnus DOT com>
patch from sos AT prospect DOT com DOT ru (Sergey Okhapkin):
* delqueue.cc (delqueue_list::process_queue): Clear queue
entry if file cannot be deleted for a reason other than
sharing violation.
Fri Sep 25 08:52:50 1998 Christopher Faylor <cgf AT cygnus DOT com>
* debug.cc: locker variables should all be static.
* syscalls.cc (_read): Call ForceCloseHandle on
thread handle since it is protected.
Thu Sep 24 18:59:25 1998 Geoffrey Noer <noer AT cygnus DOT com>
* path.cc (mount): don't verify that path is an existing
directory. Instead
* utils/mount.cc: verify that path is an existing directory
and print warning if it's not. Still do the mount.
Thu Sep 24 11:45:04 1998 Christopher Faylor <cgf AT cygnus DOT com>
* debug.cc: locker class variables must be NO_COPY since
they contain data that should not be precisely duplicated
after a fork. This hopefully fixes a "SIGSEGV" problem.
* select.cc (peek_pipe): Pipes apparently should set both
"read" and "exception" flags on EOF.
Wed Sep 23 18:26:31 1998 DJ Delorie <dj AT indy DOT delorie DOT com>
* doc/doctool.c (main): typo checking for --help
Wed Sep 23 17:46:06 1998 Christopher Faylor <cgf AT cygnus DOT com>
* path.cc (symlink_check_one): Try much harder to ensure that
CloseHandle is called on the file which was opened to check
for a symlink. Avoid obsolete check for NULL buf.
Wed Sep 23 17:11:50 1998 Christopher Faylor <cgf AT cygnus DOT com>
* syscalls.cc (_read): Close thread handle or suffer a leak.
* dir.cc (opendir): Simplify logic.
(readdir): Ditto. Close handle explicitly when hit end
of files.
(rewinddir): Close directory handle or suffer leak.
(closedir): Simplify logic.
Wed Sep 23 14:42:12 1998 Christopher Faylor <cgf AT cygnus DOT com>
patch from DJ Delorie <dj AT delorie DOT com>:
* path.cc (symlink_check_one): Don't re-define res or symlinks
will be undetectable.
Wed Sep 23 12:02:39 1998 Christopher Faylor <cgf AT cygnus DOT com>
* Change calls to api_fatal throughout to avoid need for \n
(see below).
Adapt some *_printf()/ExitProcess combinations to use api_fatal.
* winsup.h (SIGTOMASK): Generate signal mask correctly for
programs linked with newer cygwins.
* dcrt0.cc (check_sanity_and_check): Set subtract constant for
signal mask calculation based on whether binary was linked with
"older" or "newer" cygwin.
(do_global_ctors): Accept a second argument indicating whether
the ctors should always be run. Necessary in forked processes
for cygwin constructors which may do more than just allocate memory.
(checkout): Remove obsolete function.
(dll_crt0_1): Remove obsolete function call. Call do_global_ctors
with second argument TRUE.
(api_fatal): Change to a print-style function, allowing arguments.
Always emit a "\n" after a message.
(__main): Do not force running of constructors in forked processes.
* exceptions.cc (call_handler): Simplify arguments passed to this
function. Eliminate potential race by setting signal masks here.
(sig_handle): Just calculate current sigaction pointer once.
Change call_handler arguments.
* fhandler_console.cc (fhandler_console::write_normal): Output
unknown characters to screen.
(fhandler_console::write): Make signal protection synchronous.

on thread detach until a more robust scheme is developed.
* signal.cc (signal): Make signal protection synchronous.
(sigaction): Ditto.
* sigproc.cc (get_sig_dispatch_mutex): More debug info.
(release_sig_dispatch_mutex): Work around potential bug in windows
with double allocation of a mutex when WaitForSingleObject is
interrupted. Save errno here only if about to call sig_send
where it may be changed.
(wait_sig): Remove unnecessary sig_sign stuff. Add some debugging
output.
* termios.cc (tcflow): Signal protection.
(tcgetattr): Ditto.
(tcsetattr): Make signal protection synchronous.
* winsup.h: Add new extern for SIGTOMASK macro. Use it in SIGTOMASK
macro. Move errno stuff to end so that it can benefit from previous
declarations.
* configure.in: Move AC_CANONICAL_SYSTEM up a little to avoid having
configure generate some code (like the check for host type) twice.
* configure: Regenerate.
Wed Sep 23 11:49:55 1998 Christopher Faylor <cgf AT cygnus DOT com>
* path.cc (symlink_check_one): Fix handle leak resulting
from open of file to check for symlink magic. Suggested
by Corinna Vinschen <corinna DOT vinschen AT cityweb DOT de> .
Wed Sep 23 08:33:26 1998 Christopher Faylor <cgf AT cygnus DOT com>
patch from sos AT prospect DOT com DOT ru (Sergey Okhapkin):
* fhandler_tty.cc (process_ioctl): Use console handle
for ioctl operations.

including a, e, f, l, and u.
Tue Sep 22 15:18:41 1998 Geoffrey Noer <noer AT cygnus DOT com>
* path.cc (umount): remove initial system_printf
(mount): stat path, verify that it's an existing directory,
otherwise fail.
(strncasematch, strcasematch): return 0 instead of FALSE
* utils/mount.cc (reset_mounts): reset / to System drive,
not C: as was done in the old days.
Mon Sep 21 18:18:18 1998 Geoffrey Noer <noer AT cygnus DOT com>
* path.cc (mount, umount, setmntent, getmntent, endmntent):
make extern "C"
Mon Sep 21 20:37:16 1998 DJ Delorie <dj AT indy DOT delorie DOT com>
* doc/configure.in: don't try to find cc until we can correctly
configure it for a native cc in a cross build.
Mon Sep 21 17:17:14 1998 Geoffrey Noer <noer AT cygnus DOT com>
* fhandler.cc (fhandler_disk_file::check_execable_p):
don't check for .shc since that's non-standard. Check for
.exe first.
Mon Sep 21 14:57:50 1998 Geoffrey Noer <noer AT cygnus DOT com>
* doc/Makefile.in: reference -db2html in case docbook
tools aren't installed.

* fhandler.h (select_record): Clear memory in constructor.
Mon Sep 21 08:49:22 1998 Christopher Faylor <cgf AT cygnus DOT com>
patch from sos AT prospect DOT com DOT ru (Sergey Okhapkin):
* select.h: Use unsigned int to hold count in fd_set
structure or suffer alignment problems.
(WINSOCK_FD_ZERO): Back out previous change as it
is no longer needed due to the above.
Sat Sep 19 22:58:18 1998 Christopher Faylor <cgf AT cygnus DOT com>
* fhandler_console.cc (console_read): Keep looping in
ENABLE_LINE_INPUT mode when no characters are read.
This apparently means that a CTRL-C has been hit.
* select.cc (select_record::operator new): Remove.
(setlect_stuff::~select_stuff): Use delete to remove
record.
(pipe_cleanup): Remove unneeded statement.
(poll_socket): Add debugging statement.
(start_thread_socket): Add debugging statements.
* fhandler.h: Remove new operator from select_record.
* select.h: Make WINSOCK_FD_ZERO more aggressive.
* sigproc.cc (allow_sig_dispatch): Use new errno
saving method.

manipulating per_thread information.
(threadstuff): New array of per_thread objects which are
manipulated after a fork.
(read_helper_thread_info): read() thread local storage.
(waitq_storage): wait() thread local storage.
* debug.cc (class locker): New class for generic locking
of debug table manipulation. Use this throughout for
locking access to thread/debug tables.
(debug_init): Remove in favor of automatic constructor.
* debug.h: Ditto.
* fork.cc (fork): Iterate through threadstuff looking
for thread information to clear out. Should solve some
problems for Windows 95/98.
* init.cc (dll_entry): Remove thread storage initialization.
Use per_thread class for DLL_THREAD_DETEACH.
