should not be used by the child.
* select.cc (start_thread_socket): Turn off inheritance for exitsock. Don't
add exitsock to exception mask since it should never get an exception.
(socket_cleanup): Change some debug messages for consistency.
* fhandler_socket.cc (fhandler_socket::dup): Change comment wording slightly.
(exitsock_sin): Ditto.
* cygtls.cc (_cygtls::init_thread): Initialize exitsock to invalid handle.
(_cygtls::call2): Close exitsock if it is valid.
* select.cc (struct socketinf): Remove sin element.
(start_thread_socket): Initialize one SOCK_DGRAM socket per thread instead of
(apparently) expensive opening and closing of socket with each select call.
(socket_cleanup): Send a byte to the exitsock socket as a way to potentially
signal a waiting-for-socket thread to exit.
* tlsoffsets.h: Regenerate.
* path.cc (normalize_win32_path): Only look for : in second position.
Avoid infinite loop with names starting in double dots.
(mount_info::conv_to_win32_path): Do not worry about a trailing dot.
(hash_path_name): Ditto.
starting.
* child_info.h (init_child_info): Remove pid argument from declaration.
* cygheap.h (init_cygheap::pid): New element.
* dcrt0.cc (dll_crt0_0): Eliminate handling of now-noexistent cygpid parameter
in child_info struct. Set forkee to 'true' rather than cygpid since the pid
value was never used.
(dll_crt0_1): Ditto.
(_dll_crt0): Ditto.
* fork.cc (fork_child): Don't wait for sigthread. This is handled in the fork
call now.
(fork_parent): Remove obsolete pid argument from init_child_info call. Don't
do anything special with cygpid when DEBUGGING.
(fork): Delay all signals during fork.
(fork_init): Don't do anything special when DEBUGGING.
* pinfo.cc (set_myself): Remove pid parameter. Use new pid field in cygheap.
(pinfo_init): Don't pass pid argument to set_myself.
* sigproc.cc (sig_send): Wait for dwProcessId to be non-zero as well as
sendsig.
(init_child_info): Eliminate handling of pid.
(wait_sig): Implement method to temporarily hold off sending signals.
* sigproc.h (__SIGHOLD): New enum.
(__SIGNOHOLD): Ditto.
* spawn.cc (spawn_guts): Remove obsolete pid argument from init_child_info
call.
* cygheap.h (cwdstuff::drive_length): New member.
(cwdstuff::get_drive): New method.
* path.cc (normalize_win32_path): Simplify by using cwdstuff::get_drive.
(mount_info::conv_to_win32_path): Use cwdstuff::get_drive as default for /.
(cwdstuff::set): Initialize drive_length.
indicate that it is "special".
* thread.cc (pthread::exit): If __sdidinit is < 0, it was never really
initialized so reset it to 0 before calling _reclaim_reent.
* autoload.cc (NtQueryInformationFile): Return nonzero on error.
* ntdll.h (FILE_PIPE_LOCAL_INFORMATION): Add.
(NtQueryInformationFile): Fix types for last two arguments.
* pipe.cc: Include stdlib.h, limits.h, and ntdll.h.
(create_selectable_pipe): New function to create a pipe that can be used with
NtQueryInformationFile for select.
(fhandler_pipe::create): Call create_selectable_pipe instead of CreatePipe.
(pipe): Use DEFAULT_PIPEBUFSIZE as argument to create_pipe.
* select.cc: Include limits.h and ntdll.h.
(peek_pipe): Add select_printf output. Call NtQueryInformationFile to
implement select for write on pipes.
(fhandler_pipe::select_read): Reorder field assignments to be consistent with
fhandler_pipe::select_write.
(fhandler_pipe::select_write): Initialize startup, verify, cleanup, and
write_ready fields for select_record.
(fhandler_pipe::select_except): Tweak indentation to be consistent with
fhandler_pipe::select_write.
