If it's possible to get the timer to work, then I think the rest is just a small matter of programming.

Yes, getting the timer to work, canceling it when needed, etc... It's
fiddly. Especially when compared to the simplicity of
progress-reporter-update/progress-reporter-done.

They exist and are called progress-reporter-update and
progress-reporter-done respectively. They just need to be improved to
allow non-numerical non-nil updates.

That's much too tricky to implement. Making it reliable is going to
be painful. Much easier to allow progress-reporter-update to output
non-percentage messages (e.g. for bytecomp, the changing part is not
a percentage but a function name).

As I wrote earlier, `message' is the wrong place to fix this kind of problems: it doesn't have enough context to decide whether or not it's TRT to skip a message. A Lisp program that calls `message' could have good reasons to do this; not displaying those messages violates the principle of least surprise. The right place for applying this logic is in the Lisp program that calls `message'. > The net effect will be that normal messaging (where it's been a long > time since the previous message) is displayed as usual, but when we > enter a "high-message" storm, we start skipping messages. But we always > end up showing the final message, anyway. You are assuming that the final message is the only one that counts. Undoubtedly, there are use cases where this is correct. But there are others where it will be wrong, and `message' will not be able to second-guess its callers well enough to know which one is true.

I didn't know about progress-reporter, so my time wasn't wasted, at least. :-) But I wonder whether a simpler, more general function would be possible. If we're outputting stuff that's not a percentage, progress-reporter doesn't help much. `message' could work as follows: If it's been less than (say) 50th of a second since the previous message, then don't message anything. However, set up a timer in a 100th of a second's time to display that message -- if nothing else has been displayed in the mean time. The net effect will be that normal messaging (where it's been a long time since the previous message) is displayed as usual, but when we enter a "high-message" storm, we start skipping messages. But we always end up showing the final message, anyway. This would be a very simple interface for programmers to deal with (i.e., "don't worry about it"), and the user wouldn't notice anything in particular -- other than Emacs being faster in some situations. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog http://lars.ingebrigtsen.no/

There's a middle path: provide a `progress-message' function. That allows the caller to provide the semantic context that this particular message isn't critical without burdening every single application with building its own throttling updater. -- Dave Abrahams BoostPro Computing http://www.boostpro.com

Indeed. The main problem with changing `message' is that if it is
called too soon after the previous `message' we can't easily say "don't
display this one" since there may not be any subsequent message coming,
so we'd have to stash the last undisplayed message and then try and
figure out good places/times to cause them to be displayed.
So the general approach to fixing those problems is to say "use
progress-reporter-update" since this function has the advantage of
knowing that there will be a `progress-reporter-done' at some later
point, which allows it to skip a message without worries.

No doubt: Emacs redisplay is among its slowest operations, and while
"message" is handled specially so it doesn't cause a full redisplay,
it's still a slow operation.

I think it's largely unavoidable.

Any such circumstance where messages flash by quickly and repeatedly
(the repetition is important, since otherwise the speed impact is
negligible compared to the redisplay that takes place at the end
of every command anyway) is a bug, so please report them.

We could try and have such a mechanism, yes, but it might be easier to
handle it at some other level. E.g. the progress-reporter functions
attack one instance of the problem.

We've already had cases where we found that most of the time was spent
displaying messages. That's why progress-reporter doesn't call message
at every update. "A few milliseconds" sounds negligible, but if it's
done at every iteration of a loop whose body takes less than
a millisecond to run (we can do a lot of work in a millisecond on
today's machines), then it's a major slowdown.

My results are different: . in a GUI session: (16.172 2.891) . in a -nw (TTY) session: (26.125 4.734) The above is from an unoptimized build. Here are timings from an optimized build: . GUI session: (10.875 2.0) . TTY: (19.313 3.453) This shows that it takes 45% _less_ time to write the same message 10 times than 10x time to write the message once. So at best the numbers are inconclusive. Anyway, I know for a fact that Emacs does optimize screen writes in this case. Look at the function dispnew.c:update_text_area, around lines 3784 to 3967. I actually put a breakpoint there and saw that only the changing number is being redrawn while running your test code. E.g., on line 3885, I see i = 9 while stop = 11, which means Emacs will redraw only 2 characters.

I don't think it's clever enough. Try this:
--8<---------------cut here---------------start------------->8---
(let (timings)
(dolist (reps '(1 10))
(let ((start-time (current-time)))
(loop for x to 10000 do
(loop repeat reps do
(message "message #%s" x)))
(push (time-subtract (current-time) start-time) timings)))
(message "%s" (mapcar 'time-to-seconds timings)))
--8<---------------cut here---------------end--------------->8---
I get (29.539774 2.514761)
I think this shows that it takes (more than) 10x as long to write out
the same message 10 times as it does to write it out once.

But actually it's those that set the message once for each percentage (or even more often) that cause me the most (perceived) slowdown.

I don't understand the details of the feature you are requesting. Suppose `message' is being repeatedly called by some Lisp program in quick succession -- what would you like to be actually displayed? only the text of final message? If so, why is that a good idea? Most "good" uses of fast echoing display very similar messages, like "Updating... NN% done", where only the number changes. It would be a pity to lose this checkpointing feature, IMO. So you will probably say that there should be a variable to be bound to select one behavior or the other. But if Lisp code needs to bind a variable to avoid the flashing of different messages, why not avoid those messages in the first place? Your original report says: I haven't done actual timings, but I'm finding that I have a *very* strong perception that when emacs is writing lots of messages, it slows down considerably. Redisplay always slows down, but on any modern machine displaying only the echo area should take a few milliseconds at the most, so I'd be surprised if some real slowdown was involved. If you can show some timings, please do, as there could be a bug or misfeature somewhere. Anyway, can you describe the situation in which you see these flashing messages? The only one I can think of is when Emacs starts up and restores a previous session. Is that your use case, or did you see this in other situations?

I'm sorry; you've misunderstood me. I agree with you! I don't mean to pause emacs; I mean to buffer the message until it has been stable for some amount of time.

Even if this is only a perception, if it's shared by others I think it should be considered a bug. Unless the *Message* buffer is visible, these messages are often flashing by so quickly that nobody could hope to see them. It would be good, IMO, to delay updating the visible message in the minibuffer line long enough to be sure that the message just written isn't about to be overwritten so fast that the user couldn't read it anyway.
