overly-eager mouse scrolling on mac

overly-eager mouse scrolling on mac

[Sam Steingold]

In GNU Emacs 24.3.50.1 (x86_64-apple-darwin13.0.0, NS apple-appkit-1265.00)
 of 2014-01-21 on sds-MacBook-Pro.local
Windowing system distributor `Apple', version 10.3.1265
Configured using: `configure --with-ns'

Whenever I touch the mouse, emacs scrolls like crazy, starts blinking
(visible-bell is on), and *Message* contains these:

byte-code: End of buffer [5 times]
byte-code: End of buffer [5 times]
byte-code: Beginning of buffer [7 times]

lossage is:

<double-wheel-down> <wheel-right> <wheel-down> <wheel-down>
<double-wheel-down> <triple-wheel-down> <triple-wheel-down>
<triple-wheel-down> <triple-wheel-down> <wheel-up>
<double-wheel-up> <wheel-down> <double-wheel-down>
<wheel-up> <double-wheel-up> <triple-wheel-up> <triple-wheel-up>
<wheel-up> <select-window> <wheel-up> <double-wheel-up>
<triple-wheel-up> <triple-wheel-up> <triple-wheel-up>
<triple-wheel-up> <triple-wheel-up> <wheel-down> <double-wheel-down>
<triple-wheel-down> <triple-wheel-down> <triple-wheel-down>
<triple-wheel-down> <triple-wheel-down> C-h l

is this a known bug?
feature?

I suspect that there is a timing parameter in the mouse handling code
which is too small...

PS. All the other applications (firefox &c) behave normally.

The blinking thing has been discussed in bug 16196.  There is a mwheel
workaround in there.

As for "crazy", that is not a clear technical term so I don't know what
that means.  If you mean that is scrolls very fast, I guess you have to
either fix mwheel or adjust mouse acceleration in OSX settings.

Here (with Magic mouse and trackpad) the speed is reasonable.  Faster
than GNU/Linux/Gtk+ on the same hardware, but still OK.

Thanks for the pointer.
Your problem is slightly different from mine:
you don't like the beeps,
I don't like the scroll amount.

> There is a mwheel workaround in there.

Well, the workaround is only a partial fix. (see below)

My problem is that there are too many mouse events are generated,
so a touch to the mouse results in a huge scroll.
Basically, a scroll means either end-of-buffer or beginning-of-buffer.

All the other applications seem to handle the mouse as I want them too.
The problem seems to be with Emacs.

Okay, so you are confirming my impression that the problem is with Emacs.
Thanks.

elp-instrument-function appears to indicate that mwheel-scroll is called
much more often than I want it to be called - 20+ times for a simple
touch of the mouse.

For what it's worth, I was suffering from exactly the same thing and
eventually unbound the mwheel stuff altogether and simply rebound them to
the following. After that, scrolling was sane again.

(defun scroll-up-one ()
  (interactive)
  (scroll-up 1))

(defun scroll-down-one ()
  (interactive)
  (scroll-down 1))

(defun scroll-up-double-speed ()
  (interactive)
  (scroll-up 3))

(defun scroll-down-double-speed ()
  (interactive)
  (scroll-down 3))

(global-set-key (kbd "<mouse-4>") 'scroll-down-one)
(global-set-key (kbd "<mouse-5>") 'scroll-up-one)
(global-set-key (kbd "<double-mouse-4>") 'scroll-down-double-speed)
(global-set-key (kbd "<double-mouse-5>") 'scroll-up-double-speed)
(global-set-key (kbd "<wheel-up>") 'scroll-down-one)
(global-set-key (kbd "<wheel-down>") 'scroll-up-one)
(global-set-key (kbd "<double-wheel-up>") 'scroll-down-double-speed)
(global-set-key (kbd "<double-wheel-down>") 'scroll-up-double-speed)

You can probably get the same kind of result by tweaking
mouse-wheel-scroll-amount as in:

  (setf (car mouse-wheel-scroll-amount) 1)

But this "shouldn't" be needed.  IOW we should try and figure out why
you get so many scroll events even for short moves.

To this end, for the people seeing this problem: what are you using
for a mouse? I dont see it on my macbook trackpad or my logitech
trackman marble wheel, but neither of those are really typical.

I do not have this problem with the macbook trackpad either.
I do however have this problem with the apple wireless mouse.

I spoke too soon: the problem _is_ present, but it is _much_ less pronounced.
(I have to scroll with 2 finger for emacs to be overloaded with scroll events)

> I do however have this problem with the apple wireless mouse.

"Apple Magic Mouse" connected via USB.
(scrolling with one finger is enough).
