+GOAL
+----
+
+The goal of this branch is to implement support for opening multiple,
+different tty devices and simultaneous X and tty frames from a single
+Emacs session.
+
+Some use cases:
+Emacs is notoriously slow at startup, so most people use another
+editor or emacsclient for quick editing jobs from the console.
+Unfortunately, emacsclient was very awkward to use, because it did not
+support opening a new Emacs frame on the current virtual console.
+Now, with multi-tty support, it can do that. (Emacsclient starts up
+faster than vi!)
+
+Some Gnus users (including me) run Gnus in an X frame in its own Emacs
+instance, which they typically leave running for weeks. It would be
+nice if they could connect to this instance from a remote ssh session
+and check their messages without opening a remote X frame or resorting
+to gnus-slave.

+STATUS
+------
+
+The branch is now very stable and almost full-featured. All of the
+major problems have been fixed, only a few minor issues remain. (It
+still needs to be ported to Windows/Mac/DOS, though.) Both multiple
+tty device support and simultaneous X and tty frame support works
+fine. Emacsclient has been extended to support opening new tty and X
+frames. It has been changed open new Emacs frames by default.
+
+The multi-tty branch has been scheduled for inclusion in the next
+major release of Emacs (version 22). I expect the merge into the
+development trunk to occur sometime during next year (2005), after the
+merge of the Unicode branch.
+
+Please let me know if you find any bugs in this branch.
+
+Known problems:
+
+ * Mac, Windows and DOS support is broken, probably doesn't
+ even compile -- this will be solved later.
+
+ * Tested on GNU/Linux, Solaris 8, FreeBSD and OpenBSD.

+
+HOW TO GET THE BRANCH
+---------------------
+
+The branch uses GNU Arch (http://www.gnuarch.org) for version control.
+
+Retrieving the latest version of the branch:
+
+ tla register-archive lorentey@elte.hu--2004 http://lorentey.hu/arch/2004/
+ tla get lorentey@elte.hu--2004/emacs--multi-tty <directory>
+
+This incantation uses my private archive mirror that is hosted on a
+relatively low-bandwidth site; if you are outside Hungary, you will
+probably want to you use the Arch supermirror instead:
+
+ tla register-archive lorentey@elte.hu--2004 http://mirrors.gnuarch.org/lorentey@elte.hu--2004/
+ tla get lorentey@elte.hu--2004/emacs--multi-tty <directory>
+
+(I use a recent tla development snapshot, but any of the released
+versions of arch will do fine, I think.) My GPG key id is 0FB27A3F;
+it is available from hkp://wwwkeys.eu.pgp.net/, or my homepage at
+http://lorentey.hu/rolam/gpg.html)
+
+To update your source tree to the latest revision after the first
+checkout, simply use the following command:
+
+ tla replay lorentey@elte.hu--2004/emacs--multi-tty--0
+
+If you are interested, you can find more information about Arch on
+http://wiki.gnuarch.org/. It's a wonderful source control system, I
+highly recommend it.
+
+If you don't have tla, the branch has a homepage from which you can
+download conventional patches against Emacs CVS HEAD:

+
+
+HOW TO COMPILE
+--------------
+
+The multi-tty branch is compiled the same way as Emacs itself:
+
+ ./configure <your favourite options>
+ make bootstrap
+ make install
+
+HOW TO TEST IT
+--------------
+
+To try out the multi-tty branch start up the Emacs server with the
+following commands:
+
+ emacs
+ M-x server-start
+
+and then (from a shell prompt on another terminal) start emacsclient
+with
+ emacsclient -t /optional/file/names... (for a tty frame)
+ emacsclient /optional/file/names... (for an X frame)
+
+(Make sure both emacs and emacsclient are multi-tty versions.)
+You'll hopefully have two fully working, independent frames on
+separate terminals. The new frame is closed automatically when you
+finish editing the specified files (C-x #), but delete-frame (C-x 5 0)
+also works. Of course, you can create frames on more than two tty
+devices.
+
+Creating new frames on the same tty with C-x 5 2 works, and they
+behave the same way as in previous Emacs versions. If you exit emacs,
+all terminals should be restored to their previous states.
+
+This is work in progress, and probably full of bugs. You should
+always run emacs from gdb, so that you'll have a live instance to
+debug if something goes wrong. Please send me your bug reports.
+
+TIPS & TRICKS
+-------------
+
+I think the best way to use the new Emacs is to have it running inside
+a disconnected GNU screen session, and always use emacsclient for
+normal work. One advantage of this is that not a single keystroke of
+your work will be lost if the display device that you are using
+crashes, or the network connection times out, or whatever. (I had an
+extremely unstable X server for some time while I was developing these
+patches, and running Emacs this way has saved me a number of M-x
+recover-session invocations.)
+
+I use the following two bash functions to handle my Emacs sessions:
+
+,----[ ~/.bash_profile
+| # Usage: preload-emacs <name> [<waitp>]
+| #
+| # Preloads the Emacs instance called NAME in a detached screen
+| # session. Does nothing if the instance is already running. If WAITP
+| # is non-empty, the function waits until the server starts up and
+| # creates its socket; otherwise it returns immediately.
+| function preload-emacs {
+| local name="$1"
+| local waitp="$2"
+| local screendir="/var/run/screen/S-$USER"
+| local serverdir="/tmp/emacs$UID"
+| local emacs=emacs # Or wherever you installed your multi-tty Emacs
+|
+| if [ -z "$name" ]; then
+| echo "Usage: preload-emacs <name> [<waitp>]" >&2
+| return 1
+| fi
+|
+| if [ ! -e "$screendir"/*."$name" ]; then
+| if [ -e "$serverdir/$name" ]; then
+| # Delete leftover socket (for the wait option)
+| rm "$serverdir/$name"
+| fi
+| screen -dmS "$name" "$emacs" -nw --eval "(setq server-name \"$name\")" -f server-start
+| fi
+| if [ ! -z "$waitp" ]; then
+| while [ ! -e "$serverdir/$name" ]; do sleep 0.1; done
+| fi
+| return 0
+| }
+|
+| # Usage: connect-emacs <name> <args>...
+| #
+| # Connects to the Emacs instance called NAME. Starts up the instance
+| # if it is not already running. The rest of the arguments are passed
+| # to emacsclient.
+| function connect-emacs {
+| local name="$1"
+| shift
+|
+| if [ -z "$name" ]; then
+| echo "Usage: connect-emacs <name> <args>..." >&2
+| fi
+| preload-emacs "$name" wait
+| emacsclient -s "$name" "$@"
+| }
+|
+| export -f preload-emacs connect-emacs
+|
+| # Preload editor and gnus sessions for speedy initial connects.
+| preload-emacs editor
+| preload-emacs gnus

+NEWS
+----
+
+For the NEWS file: (Needs work)
+
+** Support for multiple terminal devices has been added.
+
+*** You can specify a terminal device (`tty' parameter) and a terminal
+ type (`tty-type' parameter) to `make-terminal-frame'.
+
+*** You can test for the presence of multiple terminal support by
+ testing for the `multi-tty' feature.
+
+*** Emacsclient has been extended to support opening a new terminal
+ frame. Its behaviour has been changed to open a new Emacs frame by
+ default. Use the -c option to get the old behavior of opening
+ files in the currently selected Emacs frame.
+
+*** A make-frame-on-tty function has been added to make it easier to
+ create frames on new terminals.
+
+*** New functions: frame-tty-name, frame-tty-type for accessing
+ terminal parameters, and delete-tty for closing the terminal
+ device.
+
+*** talk.el has been extended for multiple tty support.
+
+
+** Support for simultaneous graphical and terminal frames has been
+ added.
+
+*** The function `make-frame-on-display' now works during a terminal
+ session, and `make-frame-on-tty' works during a graphical session.
+
+*** The `window-system' variable has been made frame-local.
+
+*** The new `initial-window-system' variable contains the
+ `window-system' value for the first frame.

+
+THINGS TO DO
+------------
+
+** Hunt down display-related functions in frame.el and extend them all
+ to accept display ids.
+
+** Have a look at fatal_error_hook.
+
+** Check if we got term-setup-hook right.
+
+** make-frame does not correctly handle extra parameters in its
+ argument:
+
+ (frame-parameter (make-frame (list (cons 'foobar 42))) 'foobar)
+ => nil
+
+ (This is likely an error in the CVS trunk.)
+
+** Fix set-input-mode for multi-tty. It's a truly horrible interface;
+ what if we'd blow it up into several separate functions (with a
+ compatibility definition)?
+
+** Lisp-level stuff that needs to be updated for multi-tty:
+
+ - normal-erase-is-backspace-mode (simple.el) (rep. by Dan Waber)
+
+
+** The single-keyboard mode of MULTI_KBOARD is extremely confusing
+ sometimes; Emacs does not respond to stimuli from other keyboards.
+ At least a beep or a message would be important, if the single-mode
+ is still required to prevent interference. (Reported by Dan
+ Nicolaescu.) (Update: selecting a region with the mouse enables
+ single_kboard under X. This is very confusing.) Update:
+ After discussions with Richard, this will be resolved by having
+ locked displays warn the user to wait, and introducing a complex
+ protocol to remotely bail out of single-kboard mode by pressing C-g.
+
+** The terminal customization files in term/*.el tend to change global
+ parameters, which may confuse Emacs with multiple displays. Change
+ them to tweak only frame-local settings, if possible.
+
+** Dan Nicolaescu suggests that -nw should be added as an alias for -t
+ in emacsclient. Good idea. (Alas, implementing this is not
+ trivial, getopt_long does not seem to support two-letter ``short''
+ options. Patches are welcome.) :-)
+
+** Mark Plaksin suggests that emacsclient should accept the same
+ X-related command-line arguments as Emacs. Most of the X-related
+ argument-handling is done in Lisp, so this should be quite easy to
+ implement.
+
+** Gergely Nagy suggests that C-x # should only kill the current
+ frame, not any other emacsclient frame that may have the same file
+ opened for editing. I think I agree with him.
+
+** Miles Bader suggests that C-x C-c on an emacsclient frame should
+ only close the frame, not exit the entire Emacs session. Update:
+ see above for a function that does this. Maybe this should be the
+ new default?
+
+** Very strange bug: visible-bell does not work on secondary
+ terminals in xterm and konsole. The screen does flicker a bit,
+ but it's so quick it isn't noticable.
+
+** Clean up the frame-local variable system. I think it's ugly and
+ error-prone. But maybe I just haven't yet fully understood it.
+
+** Move baud_rate to struct display.
+
+** Implement support for starting an interactive Emacs session without
+ an initial frame. (The user would connect to it and open frames
+ later, with emacsclient.)
+
+** Fix Mac support (I can't do this entirely myself). Note that the
+ current state of Mac-specific source files in the multi-tty tree
+ are not useful; before starting work on Mac support, revert to
+ pristine, pre-multi-tty versions.
+
+** Fix W32 support (I can't do this entirely myself). Note that the
+ current state of W32-specific source files in the multi-tty tree
+ are not useful; before starting work on W32 support, revert to
+ pristine, pre-multi-tty versions.
+
+** Fix DOS support (I can't do this entirely myself). Note that the
+ current state of DOS-specific source files in the multi-tty tree
+ are not useful; before starting work on DOS support, revert to
+ pristine, pre-multi-tty versions.
+
+** Do a grep on XXX and ?? for more issues.
+
+** Understand Emacs's low-level input system (it's black magic) :-)
+ What exactly does interrupt_input do? I tried to disable it for
+ raw secondary tty support, but it does not seem to do anything
+ useful. (Update: Look again. X unconditionally enables this, maybe
+ that's why raw terminal support is broken again. I really do need
+ to understand input.)
+
+** Maybe standard-display-table should be display-local.
+
+DIARY OF CHANGES
+----------------
+
+(ex-TODO items with explanations.)
+
+-- Introduce a new struct for terminal devices.
+
+ (Done, see struct tty_output. The list of members is not yet
+ complete.)
+
+-- Change the bootstrap procedure to initialize tty_list.
+
+ (Done, but needs review.)
+
+-- Change make-terminal-frame to support specifying another tty.
+
+ (Done, new frame parameters: `tty' and `tty-type'.)
+
+-- Implement support for reading from multiple terminals.
+
+ (Done, read_avail_input tries to read from each terminal, until one
+ succeeds. MULTI_KBOARD is not used. Secondary terminals don't send
+ SIGIO!)
+
+ (Update: They do, now.)
+
+ (Update2: After enabling X, they don't.)
+
+-- other-frame should cycle through the frames on the `current'
+ terminal only.
+
+ (Done, by trivially modifiying next_frame and prev_frame.)
+
+-- Support different terminal sizes.
+
+ (Done, no problem.)
+
+-- Make sure terminal resizes are handled gracefully. (Could be
+ problematic.)
+
+ (Done. We don't get automatic SIGWINCH for additional ttys,
+ though.)
+
+-- Extend emacsclient to automatically open a new tty when it connects
+ to Emacs.
+
+ (Done. It's an ugly hack, needs more work.)
+
+-- Redisplay must refresh the topmost frame on *all* terminals, not
+ just the initial terminal.
+
+ (Done, but introduced an ugly redisplay problems. Ugh.)
+
+-- Fix redisplay problems.
+
+ (Done; it turned out that the entire Wcm structure must be moved
+ inside tty_output. Why didn't I catch this earlier?)
+
+-- Provide a way for emacsclient to tell Emacs that the tty has been
+ resized.
+
+ (Done, simply forward the SIGWINCH signal.)
+
+-- Each keypress should automatically select the frame corresponding
+ to the terminal that it was coming from. This means that Emacs
+ must know from which terminal the last keyboard event came from.
+
+ (Done, it was quite simple, the input event system already
+ supported multiple frames.)
+
+-- Fix SIGIO issue with secondary terminals.
+
+ (Done, emacsclient signals Emacs after writing to the proxy pseudo
+ terminal. Note that this means that multi-tty does not work with
+ raw ttys!)
+
+ (Update: This is bullshit. There is a read_input_waiting function,
+ extend that somehow.)
+
+ (Update of update: The first update was not right either, extending
+ read_input_waiting was not necessary. Secondary ttys do seem to
+ send signals on input.)
+
+ (Update^3: Not any more.)
+
+-- Make make-terminal-frame look up the `tty' and `tty-type' frame
+ parameters from the currently selected terminal before the global
+ default.
+
+ (Done.)
+
+-- Put all cached terminal escape sequences into struct tty_output.
+ Currently, they are still stored in global variables, so we don't
+ really support multiple terminal types.
+
+ (Done. It was not fun.)
+
+-- Implement sane error handling after initialization. (Currently
+ emacs exits if you specify a bad terminal type.) The helpful error
+ messages must still be provided when Emacs starts.
+
+ (Done.)
+
+-- Implement terminal deletion, i.e., deleting local frames, closing
+ the tty device and restoring its previous state without exiting
+ Emacs.
+
+ (Done, but at the moment only called when an error happens during
+ initialization. There is a memory corruption error around this
+ somewhere.) (Update: now it is fully enabled.)
+
+-- Implement automatic deletion of terminals when the last frame on
+ that terminal is closed.
+
+ (Done.)
+
+-- Restore tty screen after closing the terminal.
+
+ (Done, we do the same as Emacs 21.2 for all terminals.)
+
+-- 'TERM=dumb src/emacs' does not restore the terminal state.
+
+ (Done.)
+
+-- C-g should work on secondary terminals.
+
+ (Done, but the binding is not configurable.)
+
+-- Deal with SIGHUP in Emacs and in emacsclient. (After this, the
+ server-frames may be removed from server.el.)
+
+ (Done, nothing to do. It seems that Emacs does not receive SIGHUP
+ from secondary ttys, which is actually a good thing.) (Update: I
+ think it would be a bad idea to remove server-frames.)
+
+-- Change emacsclient/server.el to support the -t argument better,
+ i.e. automatically close the socket when the frame is closed.
+
+ (Seems to be working OK.)
+
+-- Fix mysterious memory corruption error with tty deletion. To
+ trigger it, try the following shell command:
+
+ while true; do TERM=no-such-terminal-definition emacsclient -h; done
+
+ Emacs usually dumps core after a few dozen iterations. (The bug
+ seems to be related to the xfreeing or bzeroing of
+ tty_output.Wcm. Maybe there are outside references to struct Wcm?
+ Why were these vars collected into a struct before multi-tty
+ support?)
+
+ (Done. Whew. It turned out that the problem had nothing to do
+ with hypothetical external references to Wcm, or any other
+ tty_output component; it was simply that delete_tty closed the
+ filehandles of secondary ttys twice, resulting in fclose doubly
+ freeing memory. Utterly trivial matter. I love the C's memory
+ management, it puts hair on your chest.)
+
+-- Support raw secondary terminals. (Note that SIGIO works only on
+ the controlling terminal.) Hint: extend read_input_waiting for
+ multiple ttys and hopefully this will be fixed.
+
+ (Done, it seems to have been working already for some time. It
+ seems F_SETOWN does work, after all. Not sure what made it fail
+ earlier, but it seems to be fixed (there were several changes
+ around request_sigio, maybe one of them did it).
+ read_input_waiting is only used in sys_select, don't change
+ it.) (Update: After adding X support, it's broken again.)
+ (Update^2: No it isn't.) :-)
+
+-- Find out why does Emacs abort when it wants to close its
+ controlling tty. Hint: chan_process[] array. Hey, maybe
+ noninterrupt-IO would work, too? Update: no, there is no process
+ for stdin/out.
+
+ (Done. Added add/delete_keyboard_wait_descriptor to
+ term_init/delete_tty. The hint was right, in a way.)
+
+-- Issue with SIGIO: it needs to be disabled during redisplay. See if
+ fcntl kernel behaviour could be emulated by emacsclient.
+
+ (Done. Simply disabled the SIGIO emulation hack in emacsclient.)
+ (Update: it was added back.) (Update^2: and removed again.)
+
+-- server.el: There are issues with saving files in buffers of closed
+ clients. Try editing a file with emacsclient -f, and (without
+ saving it) do a delete-frame. The frame is closed without
+ question, and a surprising confirmation prompt appears in another
+ frame.
+
+ (Done. delete-frame now asks for confirmation if it still has
+ pending buffers, and modified buffers don't seem to be deleted.)
+
+-- emacsclient.el, server.el: Handle eval or file open errors when
+ doing -t.
+
+ (Done.)
+
+-- Make parts of struct tty_output accessible from Lisp. The device
+ name and the type is sufficient.
+
+ (Done, see frame-tty-name and frame-tty-type.)
+
+-- Export delete_tty to the Lisp environment, for emacsclient.
+
+ (Done, see delete-tty.)
+
+-- Get rid of the accessor macros in termchar.h, or define macros for
+ all members.
+
+ (Done.)
+
+-- Move device-specific parameters (like costs) commonly used by
+ device backends to a common, device-dependent structure.
+
+ (Done. See struct display_method in termhooks.h.)
+
+-- Fix X support.
+
+ (Done. Well, it seems to be working.)
+
+-- Allow simultaneous X and tty frames. (Handling input could be
+ tricky. Or maybe not.)
+
+ (Done. Allowed, that is. It is currently extremely unstable, to
+ the point of being unusable. The rif variable causes constant
+ core dumps. Handling input is indeed tricky.)
+
+-- Rewrite multi-tty input in terms of MULTI_KBOARD.
+
+ (Done. In fact, there was no need to rewrite anything, I just
+ added a kboard member to tty_display_info, and initialized the
+ frame's kboard from there.)
+
+-- Fix rif issue with X-tty combo sessions. IMHO the best thing to do
+ is to get rid of that global variable (and use the value value in
+ display_method, which is guaranteed to be correct).
+
+ (Done, did exactly that. Core dumps during combo sessions became
+ much rarer. In fact, I have not yet met a single one.)
+
+-- Add multi-tty support to talk.el.
+
+ (Done.)
+
+-- Clean up the source of emacsclient. It is a mess.
+
+ (Done, eliminated stupid proxy-pty kludge.)
+
+-- Fix faces on tty frames during X-tty combo sessions. There is an
+ init_frame_faces call in init_sys_modes, see if there is a problem
+ with it.
+
+ (Done, there was a stupid mistake in
+ Ftty_supports_face_attributes_p. Colors are broken, though.)
+
+-- C-x 5 2, C-x 5 o, C-x 5 0 on an emacsclient frame unexpectedly
+ exits emacsclient. This is a result of trying to be clever with
+ delete-frame-functions.
+
+ (Fixed, added delete-tty-after-functions, and changed server.el to
+ use it.)
+
+-- Something with (maybe) multi-keyboard support broke function keys
+ and arrows on ttys during X+tty combo sessions. Debug this.
+
+ (I can't reproduce it, maybe the terminal type was wrong.)
+
+-- Fix input from raw ttys (again).
+
+ (Now it seems to work all right.)
+
+-- During an X-tty combo session, a (message "Hello") from a tty frame
+ goes to the X frame. Fix this.
+
+ (Done. There was a safeguard against writing to the initial
+ terminal frame during bootstrap which prevented echo_area_display
+ from working correctly on a tty frame during a combo session.)
+
+-- If there are no frames on its controlling terminal, Emacs should
+ exit if the user presses C-c there.
+
+ (Done, as far as possible. See the SIGTERM comment in
+ interrupt_signal on why this seems to be impossible to solve this
+ in general.)
+
+-- During an X session, Emacs seems to read from stdin. Also, Emacs
+ fails to start without a controlling tty.
+
+ (Fixed by replacing the troublesome termcap display with a dummy
+ bootstrap display during bootstrap.
+
+-- Do tty output through struct display, like graphical display
+ backends.
+
+ (Done.)
+
+-- Define an output_initial value for output_method for the initial
+ frame that is dumped with Emacs. Checking for this frame (e.g. in
+ cmd_error_internal) is ugly.
+
+ (Done, broking interactive temacs.)
+
+-- The command `emacsclient -t -e '(delete-frame)'' fails to exit.
+
+ (Fixed.)
+
+-- frame-creation-function should always create a frame that is on the
+ same display as the selected frame. Maybe frame-creation-function
+ should simply be removed and make-frame changed to do the right
+ thing.
+
+ (Done, with a nice hack. frame-creation-function is now frame-local.)
+
+-- Fix C-g on raw ttys.
+
+ (Done. I disabled the interrupt/quit keys on all secondary
+ terminals, so Emacs sees C-g as normal input. This looks like an
+ overkill, because emacsclient has extra code to pass SIGINT to
+ Emacs, so C-g should remain the interrupt/quit key on emacsclient
+ frames. See the next entry why implementing this distinction would
+ be a bad idea.)
+
+-- Make sure C-g goes to the right frame with ttys. This is hard, as
+ SIGINT doesn't have a tty parameter. :-(
+
+ (Done, the previous change fixes this as a pleasant side effect.)
+
+-- I have seen a case when Emacs with multiple ttys fell into a loop
+ eating 100% of CPU time. Strace showed this loop:
+
+ getpid() = 30284
+ kill(30284, SIGIO) = 0
+ --- SIGIO (I/O possible) @ 0 (0) ---

+
+ I have seen something similar with a single X frame, but have not
+ been able to reproduce it for debugging.
+
+ Update: This may have been caused by checking for nread != 0
+ instead of nread > 0 after calling read_socket_hook in
+ read_avail_input.
+
+ (Fixed. This was caused by unconditionally including stdin in
+ input_wait_mask in init_process. The select call in
+ wait_reading_process_input always returned immediately, indicating
+ that there is pending input from stdin, which nobody read.
+
+ Note that the above strace output seems to be an unrelated but
+ similar bug. I think that is now fixed.)
+
+-- Exiting Emacs while there are emacsclient frames doesn't restore the
+ ttys to their default states.
+
+ (This seems to be fixed by some previous change.)
+
+-- Allow opening an X session after -nw.
+
+ (Done.)
+
+-- Fix color handling during tty+X combo sessions. (It seems that tty
+ sessions automatically convert the face colors to terminal colors
+ when the face is loaded. This conversion must happen instead on
+ the fly in write_glyphs, which might be problematic, as color
+ approximation is currently done in lisp (term/tty-colors.el).)
+ (Update: hm, colors seem to work fine if I start emacs with -nw and
+ then create an X frame. Maybe it's just a small buglet somewhere.)
+
+ (Seems to be fixed. The problem was in startup.el, it did not
+ initialize tty colors when the initial window system was
+ graphical.)
+
+-- emacs -nw --eval '(y-or-n-p "Foobar")' segfaults. (Reported by
+ Romain Francoise)
+
+ (Fixed, there was a keyboard initialization problem.)
+
+-- Fix interactive use of temacs. There are face-related SEGVs, most
+ likely because of changes in realize_default_face, realize_face.
+
+ (Fixed.)
+
+-- Don't exit Emacs when the last X connection fails during a
+ multi-display session.
+
+ (Fixed.)
+
+-- Dan Nicolaescu noticed that starting emacsclient on the same
+ terminal device that is the controlling tty of the Emacs process
+ gives unexpected results.
+
+ (Fixed.)
+
+-- Istvan Marko reported that Emacs hang on ttys if it was started
+ from a shell script.
+
+ (Fixed. There was a bug in the multi-tty version of
+ narrow_foreground_group. tcsetpgrp blocks if it is called from a
+ process that is not in the same process group as the tty.)
+
+-- emacsclient -t from an Emacs term buffer does not work, complains
+ about face problems. This can even lock up Emacs (if the recursive
+ frame sets single_kboard). Update: the face problems are caused by
+ bugs in term.el, not in multi-tty. The lockup is caused by
+ single_kboard mode, and is not easily resolvable. The best thing to
+ do is to simply refuse to create a tty frame of type `eterm'.
+
+ (Fixed, changed emacsclient to check for TERM=eterm. The face
+ complaints seem to be caused by bugs in term.el; they are not
+ related to multi-tty.)
+
+-- Find out the best way to support suspending Emacs with multiple
+ ttys. My guess: disable it on the controlling tty, but from other
+ ttys pass it on to emacsclient somehow. (It is (I hope) trivial to
+ extend emacsclient to handle suspend/resume. A `kill -STOP' almost
+ works right now.)
+
+ (Done. I needed to play with signal handling and the server
+ protocol a bit to make emacsclient behave as a normal UNIX program
+ wrt foreground/background process groups.)
+
+-- There is a flicker during the startup of `emacs -nw'; it's as if
+ the terminal is initialized, reset and then initialialized again.
+ Debug this. (Hint: narrow_foreground_group is called twice during
+ startup.)
+
+ (This is gone.)
+
+-- Robert Chassell has found serious copy-paste bugs with the
+ multi-tty branch. There seem to be redisplay bugs while copying
+ from X to a terminal frame. Copying accented characters do not
+ work for me.
+
+ (Patch-124 should fix this, by changing the interprogram-*-function
+ variables to be frame-local, as suggested by Mark Plaksin
+ (thanks!). I think that the redisplay bugs are in fact not bugs,
+ but delays caused by single_kboard --> perhaps MULTI_KBOARD should
+ be removed.)
+
+-- frame-creation-function was removed, which might be a bad idea.
+ Think up a compatible solution.
+
+ (It was an internal interface that may be changed when necessary.)
+
+-- Change Lisp code not to (getenv "TERM"); use the `tty-type' frame
+ parameter or the frame-tty-type function instead. (M-x tags-search
+ "TERM" helps with this.) Update: Actually, all getenv invocations
+ should be checked for multi-tty compatibility, and an interface
+ must be implemented to get the remote client's environment.
+
+ (Done. Only getenv calls in lisp/term/*.el were changed; other
+ calls should be mostly left as they are.)
+
+-- Add an elaborate mechanism for display-local variables. (There are
+ already a few of these; search for `terminal-local' in the Elisp
+ manual.)
+
+ (Not needed. Display-local variables could be emulated by
+ frame-local variables.)
+
+-- Emacs assumes that all terminal frames have the same locale
+ settings as Emacs itself. This may lead to bogus results in a
+ multi-locale setup. (E.g., while logging in from a remote client
+ with a different locale.)
+ (Update after new bugreport by Friedrich Delgado Friedrichs:
+ (at least) the structs terminal_coding and keyboard_coding in
+ coding.c must be moved to struct display, and the Lisp interface
+ [set-]keyboard-coding-system must be adapted for the change.)
+
+ (Fixed. Emacs now uses the locale settings as seen by the
+ emacsclient process for server tty frames.)
+
+
+-- Make `struct display' accessible to Lisp programs. Accessor functions:
+
+ (displayp OBJECT): Returns t if OBJECT is a display.
+ => Implemented as display-live-p.
+
+ (display-list): Returns list of currently active displays.
+ => Implemented.
+
+ (selected-display): Returns the display object of the selected frame.
+ => Not strictly necessary, but implemented anyway.
+
+ (frame-display FRAME): Returns the display object of FRAME.
+ => Implemented.
+
+ (display-frames DISPLAY): Returns a list of frames on DISPLAY.
+ => Already implemented, see frames-on-display-list.
+
+ (display-type DISPLAY): Returns the type of DISPLAY, as a
+ symbol. (See `framep'.)
+ => Implemented as display-live-p.
+
+ (display-device DISPLAY): Returns the name of the device that
+ DISPLAY uses, as a string. (E.g: "/dev/pts/16", or
+ ":0.0")
+ => Implemented as display-name.
+
+ etc.
+
+ See next issue why this is necessary.
+
+ (Update: The consensus on emacs-devel seems to be to do this via
+ integer identifiers. That's fine by me.)
+
+ (Done.)
+
+-- The following needs to be supported:
+
+ $ emacsclient -t
+ C-z
+ $ emacsclient -t
+ (This fails now.)
+
+ The cleanest way to solve this is to allow multiple displays on the
+ same terminal device; each new emacsclient process should create
+ its own display. As displays are currently identified by their
+ device names, this is not possible until struct display becomes
+ accessible as a Lisp-level object.
+
+ (Done.)

-the branch they are talking about. Likewise, a "cvs checkout" without
-the "-r" option results in this branch.

+
+This is the "multi-tty" branch. It contains a version of Emacs that
+is able to create frames on multiple display devices and display
+types, including multiple tty devices and tty+X combined sessions.
+The branch has an enhanced version of emacsclient that is capable of
+opening a new Emacs frame on the terminal it runs on.
+
+Commit access to the multi-tty branch is only available to its
+maintainer, Károly LÅ\91rentey (lorentey@elte.hu). The best way to
+contribute to the project is to create your own public Arch branch,
+and publish your changes there. (I will then be able to easily "pull"
+your changes into the multi-tty branch.)
+
+The branch is scheduled for inclusion in the next major release of
+Emacs, version 22.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-\f
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-\f
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-\f
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-\f
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) year name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-;; X-win.el: this file is loaded from ../lisp/startup.el when it recognizes
-;; that X windows are to be used. Command line switches are parsed and those
-;; pertaining to X are processed and removed from the command line. The
-;; X display is opened and hooks are set for popping up the initial window.
+;; X-win.el: this file defines functions to initialize the X window
+;; system and process X-specific command line parameters before
+;; creating the first X frame.
+
+;; Note that contrary to previous Emacs versions, the act of loading
+;; this file should not have the side effect of initializing the
+;; window system or processing command line arguments (this file is
+;; now loaded in loadup.el). See the variables
+;; `handle-args-function-alist' and
+;; `window-system-initialization-alist' for more details.
;; startup.el will then examine startup files, and eventually call the hooks
;; which create the first window(s).
;; An alist of X options and the function which handles them. See
;; ../startup.el.
