(Sigh.) I obviously need to remember to separate individual changes
to multiple commits.
src/emacsclient.c: Improved error handling.
(decode_options): Changed frame option (again) from -f to -t.
(print_help_and_exit): Ditto.
(copy_from_to): Check EINTR after write, not EAGAIN. Removed SIGIO hack.
(pty_conversation): Handle errors transmitted through the socket.
Handle pty errors by not reading from it anymore.
(main): Restore correct errno after socket_status failed. Send -tty
on -t, not -pty.
lisp/server.el (server-process-filter): Watch -tty, not -pty.
Use make-frame-on-tty instead of make-terminal-frame.
Don't set newframe to t if make-frame-on-tty failed.
Don't delete frames here. Print correct message when there are no
files to edit, but a new frame was requested.
(server-sentinel): Delete the frame after the process.
(server-handle-delete-frame): New function for delete-frame-functions.
(server-start): Add server-handle-delete-frame to delete-frame-functions.
(server-buffer-done): Don't delete frames here.
src/alloc.c (mark_ttys): Add prototype.
(Fgarbage_collect): Call mark_ttys.
src/emacs.c: (shut_down_emacs): Don't flush stdout before
reset_sys_modes().
src/process.c (add_keyboard_wait_descriptor_called_flag): Removed.
(add_keyboard_wait_descriptor): Removed stdin hack.
src/sysdep.c: Unconditionally include sysselect.h.
(old_fcntl_flags): Changed to an array.

(narrow_foreground_group, widen_foreground_group): Use setpgid, not
setpgrp.

git-archimport-id: lorentey@elte.hu--2004/emacs--multi-tty--0--patch-28

prototypes.
src/dispnew.c (window_change_signal): Update call to get_tty_size.
src/frame.c (Fmake_terminal_frame): Ditto.
src/keyboard.c (Fsuspend_emacs): Ditto.
src/sysdep.c: Eliminate tty_outputs, wherever possible. (The
exceptions are init_sys_modes and reset_sys_modes, which need access
to tty-local parameters).
(init_baud_rate): Change tty_output parameter to a simple file descriptor.
(narrow_foreground_group, widen_foreground_group): Ditto.
(tabs_safe_p, get_tty_size): Ditto.
(init_sys_modes): Update narrow_foreground_group invocation.
(reset_sys_modes): Update widen_foreground_group invocation.
(request_sigio)[!FASYNC && STRIDE]: Fix function signature.
src/term.c (delete_tty): Only close output file handle if it is
different from input. Re-enable freeing of Wcm.
(term_init): Update get_tty_size, tabs_safe_p and init_baud_rate
invocations.
lib-src/emacsclient.c (here): Renamed to frame.
(longopts): Change --here to --frame. The -h short option may be
confused with --help.
(decode_options, print_help_and_exit): Update to reflect above changes.
(main): Ditto.
lisp/server.el (server-start): Fix frame-live-p call syntax.
(server-process-filter): Handle 'emacsclient -f' without file
arguments. Don't return any values to emacsclient when 'emacsclient
-f -e'.
(server-switch-buffer): Prevent infinite recursion when there are no
files to edit.
git-archimport-id: lorentey@elte.hu--2004/emacs--multi-tty--0--patch-27
lisp/server.el (server-start): Delete any remaining opened frames of
the previous server.
(server-sentinel, server-process-filter): Force deleting the frame.
(server-buffer-done): Ditto.
git-archimport-id: lorentey@elte.hu--2004/emacs--multi-tty--0--patch-25
lisp/server.el (server-sentinel): Delete frame if alive. Fix delq
invocation on server-frames.
(server-process-filter, server-buffer-done): Fix delq invocation on
server-frames.
src/cm.c (cmputc): Abort on write error, see what happens.
src/keyboard.c (read_avail_input): Do delete_tty on read errors.
git-archimport-id: lorentey@elte.hu--2004/emacs--multi-tty--0--patch-21
lib-src/emacsclient.c (main_argc, main_argv): New variables.
(main): Initialize them.
(fail): Use them.
(window_change, copy_from_to): Don't kill if emacs_pid is zero.
(pty_conversation): Watch the command socket, too. Read emacs_pid
here. Emacs and emacsclient could deadlock if Emacs tried to do a
reset_sys_modes before sending its pid.
lisp/server.el: Automatically delete the client frame when done editing.
(server-frames): New variable.
(server-process-filter, server-sentinel, server-buffer-done): Use it.
(server-process-filter): Do a redisplay before evaluating other
parameters. (Prevents "emacsclient -h -e '(delete-frame)'" from
messing up the system.
src/dispextern.h: Update prototypes.
src/dispnew.c (window_change_signal): Do nothing if !term_initted.
(init_display): Set the frame size from the tty data after term_init.
src/emacs.c (main): Make sure things that init_sys_modes needs are
initialized before init_display (which calls init_sys_modes now).
(sort_args): Use xfree, not free.
(shut_down_emacs) [!EMACS_HAVE_TTY_PGRP]: Use reset_all_sys_modes
instead of reset_sys_modes.
src/frame.c (make_terminal_frame): Sigh. Move terminal initialization
back to the middle of frame setup. Handle errors by making sure that
the delete_tty() called from term_init() will see and delete this
frame.
(Fdelete_frame): Kill the frame before calling delete_tty(). Fix
condition for tty deletion.
src/keyboard.c (Fset_input_mode): Use reset_sys_modes on the current
terminal only.
src/lisp.h: Remove duplicate prototypes.
src/msdos.c (croak): use reset_all_sys_modes().
src/sysdeps.c (init_baud_rate): Added tty parameter, use it instead of CURTTY.
(child_setup_tty): Reset sigio on stdin, not CURTTY().
(reset_sigio): Added fd parameter, put explicit fcntl there.
(request_sigio, unrequest_sigio)[FASYNC]: Simply block/unblock the
SIGIO signal, don't touch the file params. There are multiple ttys
now, and we can't disable the SIGIO from emacsclient.
(get_tty_size)[VMS]: Use tty_out instead of CURTTY().
(reset_sys_modes): Don't call cursor_to, clear_end_of_line; call
cmgoto and tty_clear_end_of_line instead. The frame may already be
dead. Updated reset_sigio call.
src/term.c (clear_and_of_line): Separate tty-dependent stuff to
tty_clear_end_of_line() for reset_sys_modes.
(tty_clear_end_of_line): New function.
(term_init): Added frame parameter, don't use selected_frame.
Set the frame's output_data.tty value (in case there is an error
later). Set the frame size in Wcm, not in the frame. Only free the
termcap buffer if there is a termcap-related error. Call
init_sys_modes last, not first.
(deleting_tty): New variable.
(delete_tty): Use it for handling recursive calls. Free deleted tty,
except its Wcm (there is still a dangling reference somewhere).
git-archimport-id: lorentey@elte.hu--2004/emacs--multi-tty--0--patch-19
lisp/server.el (server-process-filter): Switch to the new terminal frame.
src/frame.c (Fdelete_frame): Delete the tty if this was its the last frame.

parameters from the currently selected terminal before the global
default.
(Fdelete_frame): Make sure that the new selected frame is live.

(read_avail_input): Fix C syntax. Update references to meta_key.

record_unwind_protect.
(Fset_input_mode): Update references to meta_key.
(Fcurrent_input_mode): Ditto.
src/sysdep.c (init_sys_modes): Updated old_tty and meta_key
references. Don't call set_terminal_modes, it needs termcap strings.
(reset_sys_modes): Call tty_reset_terminal_modes instead of
reset_terminal_modes. Updated old_tty references.
src/term.c: Massive updates throuout the file.
(TS_*, TN_*): Moved to struct tty_output.
(RPov, delete_in_insert_mode se_is_so, costs_set, insert_mode): Ditto.
(standout_mode, specified_window, tty_cursor_hidden): Ditto.

(tty_hide_cursor, tty_show_cursor): Ditto.
(background_highlight, highlight_if_desired): Ditto.
(tty_capable_p): Changed first parameter to tty_output.
(term_init): Make sure top_frame is initialized. Don't exit on errors
if this would have been a secondary terminal. Call set_terminal_modes
on the end.
(delete_tty): New function.
(delete_tty_1): New function.
(print_all_frames): New function, marginally useful for debugging.
src/termchar.h (struct tty_output): Changed old_tty to be a pointer.
Removed old_tty_valid member. Added tty-specific variables from term.c.
src/xfaces.c (Ftty_supports_face_attributes_p): Update for new
tty_capable_p.

the tty that was read. Slight rearrangement of tty loop.

(discard_tty_input): Discard input from all ttys on APOLLO, too.
Whatever it is.
(narrow_foreground_group, widen_foreground_group): Added tty parameter
(not really useful, the functions only work on the controlling tty.)

src/term.c Added tty parameters to all Wcm macro calls.
Standardised updating_frame vs. selected frame and tty_output access.
(term_init): Allocate Wcm.
