Subject: [PATCH]: xterm-mouse-mode clicks in the modeline dont use the keymap
 properties of the modeline strings
Date: Wed, 01 Nov 2017 14:45:32 +0100

1. emacs -Q -nw
2. M-x xterm-mouse-mode RET
3. mouse-1 click on the `*scratch*' string of the modeline.
4. Nothing happens. Expected behaviour would be, to change to the next buffer `*Messages*'.

This seems to be a bug in `keyboard.c:read_key_sequence'. After reading
the first characters of the xterm click event, they are remapped with
`keyremap_step' at line 9605 using the `input-decode-map'. The result of
this is a mouse-1 event structure, which carries the correct click
position. Unfortunately, this position isn't used, but instead, at line
9035, the position of the variable `first_event' is used.

The following patch sets `first_event' (after a key translation /
remapping) to the remapped event.

Subject: bug#29104: [PATCH]: xterm-mouse-mode clicks in the modeline dont use
 the keymap properties of the modeline strings
Date: Tue, 07 Nov 2017 00:47:28 +0100

Hi,

I would like to give some more details on the patch and which problem it
tries to solve.

Ultimately I try to get better support of the mouse under xterm. The
following features currently do not work with the mouse under xterm:

1. Mouse clicks on menu-bar always brings up the left-most menu, but not
   the menu under the spot.
   
2. A mouse click on the mode-line activates the window, but does not
   trigger the local-map property on the spot.

3. When moving the mouse over some text with a mouse-face property or
   help-echo property nothing happens, because xterm-mouse-mode does not
   receive any mouse motion events from the controlling xterm (except
   during dragging operations).

I haven't looked into (1), but I am testing a solution for (2) and (3).

This patch (#29104) addresses (2). It does not implement a new feature,
but tries to make a bugfix to keyboard.c:read_key_sequence. This
function is a 900 lines nightmare of spaggheti code, full of global
state and goto's. At least it is somehow documented.

But here we go, this is what I understood so far:

The function reads input characters until some keybinding is found or
until the sequence does not form a prefix key sequence anymore. If the
trailing characters, which have been read so far, form a sequence in a
translation keymap (input-decode-map, key-translation-map,
local-function-key-map), those trailing characters are replaced by the
binding of the translation map.  Thereafter a jump back close to the
beginning of the function is made and all events up to the replacement
event are reinterpreted again.

Such jumps ("goto replay_sequence;") take place immediately after the
lines, which I introduced in the patch.  When replaying the sequence,
the variable "first_event" will be used to select the currently active
keymaps (line 9035).  In case, that the first characters are bound in a
key translation map, first_event still holds (incrorrectly, as I
presume) the first character of the translation sequence and not its
binding.

My patch takes place after a key translation has been performed.  It
checks, that the key translation is not empty, (or more precisely, that
the current event sequence is not empty),

           first_event = mock_input > 0 ? keybuf[0] : Qnil;  
                         ^^^^^^^^^^^^^^

and if so, sets the variable first_event to the first event in the
sequence.

           first_event = mock_input > 0 ? keybuf[0] : Qnil;  
                                          ^^^^^^^^^

Here, all key translations where allready replaced by their
corresponding binding.  If the current event sequence is empty,
first_event is set to Qnil, which means that the default active keymaps
should be used. This would be the case, if the raw key sequence was
bound to an empty vector in a translation map.

           first_event = mock_input > 0 ? keybuf[0] : Qnil;  
                                                      ^^^^

Now back to my original problem: mouse clicks in the mode line do not
work correctly. xterm-mouse-mode uses the input-decode-map to translate
special character sequences coming from xterm (starting with "\e[") into
proper mouse events.  Without the patch, first_event is set to ?\e.
Therefore the esc-map is used to find a binding for the mouse event,
which of cause does not work as intended. With the patch, first_event is
set to the mouse event and the binding in the local-map property will be
found.

Et vola, mouse clicks in the mode line will work :-)


Olaf


PS: You might ask, why I check for empty key translations.  I need those
    for (3).

Thanks for the detailed explanations, they help a lot.

I have a few questions.  First, why did you need this hunk:

This is no longer about input-decode-map, it's about
key-translation-map.  And xterm-mouse-mode doesn't use
key-translation-map, so why change this part?

The next question is whether this patch caters correctly to features
other than xterm-mouse-mode.  The input-decode-map is used by
terminal-specific support in xterm.el and rxvt.el -- does it still
make sense to use keybuf[0] as first_event for replaying their
sequences?

are actually unrelated to xterm-mouse and where included for symmetry,
only. But I still think, its correct to do so:

After initialization, the only place where first_event is set, is at
line 9282:

          if (NILP (first_event))
            {
              first_event = key;

Unfortunately, this line is not reached during the replay of a key
translation (either input-decode-map or key-translation-map). So after
a key translation, ideally one should check, if the first key of the
key sequence was translated, and set first_event accordingly. But
since keybuf[0] holds the first event in any case, I set first_event
unconditionally to keybuf[0].

The reason, why this bug has not been recognized so far is, that the
only use of first_event is as an argument to the function
active_maps. In that function, first_event is ignored, if it is not a
mouse event. Afaik,translations, which result in mouse events, are
only generated xterm-mouse.

Summarizing, I believe, it does no harm to also set first_event after a
key-translation-map, but I included these to hunks for consistency
only. I would understand you, if you fear, that we might not
fully understand its consequences.

Yes I think so. As mentioned before, the only use of first_event is,
in active_maps(first_event), which prepends the active maps with the
local-map property after a mouse click. If first_event is not a mouse
event, its particular value is ignored. xterm.el and rxvt.el do not
generate mouse events and are therefore not affected (but even if they
did, setting first_event to keybuf[0] would still be the right thing).

Just for reference, this is the definition of active_maps():

static Lisp_Object
active_maps (Lisp_Object first_event)
{
  Lisp_Object position
    = CONSP (first_event) ? CAR_SAFE (XCDR (first_event)) : Qnil;
      |                     |                               |
      check for compound    get mouse position              otherwise ignore
      event (mouse click)                                   first_event

  return Fcons (Qkeymap, Fcurrent_active_maps (Qt, position));
}

In a more radical approach and instead of my original patch, one can get rid off
with the variable first_event all together, see patch below. It simplifies the code
a little bit, but of course is more risky.

Oh, yes, the number of lines has fluctuated a bit, but it's been
a nightmare ever since I first saw it.  I'm impressed you found the
stamina to dig into it.

I'll take a look at it later this week-end (it will take some time for
me to re-understand the code ;-)

Indeed, I got a similar patch (see below) by simply moving your
assignment to first_event from "before the `goto replay_sequence`" to
after it (i.e. after the replay_sequence label).

Your patch looks about as good as mine.  I think they're both better
than your first patch because they fix the problem in a single place
(The Right Place).

I installed mine because it's shorter and looks more "obviously safe"
to me.  Thanks a lot for tracking it down!
