No. The term 'buffer-local' contradicts the formulation "for all buffers".

Window deletion events as well as events that remove a buffer from a window are caught by the default value only. Note in this context that 'window-old-buffer' might not even return a meaningful value if the old buffer has been deleted in the meantime. > All I see is `buffer-list-update-hook' which is run by > `get-buffer-create' (OK), but it's also run by =E2=80=98make-indirect-= buffer=E2=80=99, > =E2=80=98rename-buffer=E2=80=99, =E2=80=98kill-buffer=E2=80=99, =E2=80= =98bury-buffer-internal=E2=80=99 and > =E2=80=98select-window=E2=80=99 (all unnecessary for setting a buffer-= local value in > `window-buffer-change-functions').

It it finds a definition in version 27.1 and not in version 26.1, it doesn't want to deny that the variable might have already existed in version 22.1 and was temporarily deleted in version 25.1. martin

Thanks for the informative response. None of the symbols you mentioned are available in the emacs version I normally use, so they were all new to me. I do have two follow-up questions that could save me some time: 1) For function `window-buffer-change-functions' when set globally: the docstring says that it takes an arg FRAME. During execution of those functions, will that arg necessarily be `(selected-frame)'? 2) For function `window-buffer-change-functions' when set buffer-local: Is there a straightforward way to ensure that the value will be set for all buffers, current and future? This would be subtly different from the description of what occurs when setting the value globally, because no window-walk would be required, and it wouldn't be triggered by window deletion events.

From what I've read so far, Baruch wants to react to two events only: A window displays another buffer and a window gets selected, where the latter subsumes anything like frame selection or switching, or a frame getting focus. The former should be handled by adding a function to 'window-buffer-change-functions'. The latter should be handled by adding a function to 'window-selection-change-functions'. When these added functions (probably it's one and the same function) are run, one can use 'window-old-buffer', 'frame-old-selected-window', 'old-selected-window' and 'old-selected-frame' to individually check what has changed since the last time. For example, to find out whether a window on the frame reported by 'window-buffer-change-functions' has changed its buffer, 'walk-window-tree' for that frame with a function that checks whether 'window-buffer' for any such window differs from 'window-old-buffer'. If it does differ, you probably want to check whether that buffer should be reverted. For 'window-selection-change-functions' you probably want to just check whether the buffer of the selected window of the reported frame should be reverted. I would avoid using 'window-configuration-change-hook' because that hook also triggers when a window changed its size. All hooks are described in detail in section "28.28 Hooks for Window Scrolling and Changes" of the Elisp manual. If you have any further questions, please ask. martin

I'm needing now to focus on Rosh HaShanna preparations, and can let
emacs distract me for the next few days, but from memory, on tty emacs:
1) touch ~/foo
2) find it in emacs
3) bury the frame so it's not human-visible
3.1) OT: I find it useful to globally bind C-x 5 b to function
select-frame-by-name, because I do this routinely as part of my
workflow. Another option might be C-x 5 2.
4) M-! echo "bar" >> ~/foo
5) switch to the buried frame
6) Depending upon your timing, you'll need to wait up to
auto-revert-interval seconds for the buffer to be updated.

It maybe could all be solved if there were a hook for frame change of
state (eg. getting/losing focus, being raised/buried). It's surprising
to me that such events were never thought significant enough in emacs to
merit a hook.

Actually testing the code would be helpful.

Don't know what you mean. What are you suggesting? Like I mentioned earlier, I need a few days for the Holiday. If you can test the patch, that would be great. =2D- hkp://keys.gnupg.net CA45 09B5 5351 7C11 A9D1 7286 0036 9E45 1595 8BC0

It looks to me like that's not the case: my testing seems to show that it does catch cases of changing a buffer displayed in a window but does not catch changes of frames due to functions like `other-frame' or `select-frame'. So, the good news is that I've written the code that makes the improvement for the caught cases, and I can submit that. As for the cases of changing frames, a less-desirable option would be to preempt bug-reports by documenting the limitation. Auto-revert already has other curious limitations (eg. for dired buffers it doesn't operate _at__all_ on many types of file changes), and this limitation only introduces a delay, so by comparison its a pretty mild limitation. A better option would be able to catch frame-change events. I haven't found a straightforward way to trap that. Does such a method exist? An inelegant solution that would cover most of the remaining events would be to advise :after ~4 frame functions, and to add an element to variable `move-frame-functions'. =2D- hkp://keys.gnupg.net CA45 09B5 5351 7C11 A9D1 7286 0036 9E45 1595 8BC0

I haven't tested your patch, but I'm asking myself whether it cooperates with autorevert triggered by file notifications. That is, if a file changes on disk, a notification event is sent, and autovert happens. If autorevert does not happen because the buffer is not visible, this event will be lost, and no autorevert will happen later on when the buffer becomes visible. Have you tested this scenario?

"Frame visibility" is a concept in Emacs, so changing it now, and for TTY displays on top of that, is next to unimaginable, IMO. > > Btw, what will be the effect of this option?

Maybe we should arrange it to actually auto-revert before being displayed. I envision bug reports if we don't.

In the case of TTY emacs, only one frame seems possible to ever be
visible, but each and every frame seems to be considered, let's say
'displayed'. In that situation, this patch only auto-reverts buffers
displayed on windows of the actually 'displayed' TTY frame.

Thanks. I had just taken a guess.

For users of TTY emacs (ahem, me), most assuredly. In TTY emacs, AFAICT
only one frame can ever be 'displayed' (actually visible), but function
`get-buffer-window-list' with argument ALL-FRAMES set to 'visible
returns all windows on all frames. From that function's docstring:
--8<--cut here-(start)------------------------------------------- >8
- =E2=80=98visible=E2=80=99 means consider all windows on all visible fr=
ames on
the current terminal.
--8<--cut here-(end)--------------------------------------------- >8
That behavior of function `get-buffer-window-list' may in turn be
because of the behavior of function `frame-visible-p', whose docstring
begins with:
--8<--cut here-(start)------------------------------------------- >8
Return t if FRAME is "visible" (actually in use for display).
--8<--cut here-(end)--------------------------------------------- >8
But ends with the punch-line:
--8<--cut here-(start)------------------------------------------- >8
If FRAME is a text terminal frame, this always returns t.
Such frames are always considered visible, whether or not they are
currently being displayed on the terminal.
--8<--cut here-(end)--------------------------------------------- >8
So since for the purposes of this patch, what matters is the actual user
experience, the distinction *was* needed.
Off-topic: would anything constructive result if I submit a separate
'complaint' about that behavior / judgment / decision that 'Such
frames are always considered visible'?

I kind of mentioned this in my note: From my testing, at the instant an
un-reverted buffer is displayed, it is in its 'stale' state but is also
instantly considered for auto-revert. The *theoretical* maximum delay to
the auto-revert then being performed is based upon defcustom
`auto-revert-interval', whose default is five seconds. In practice, the
possible downsides are that: 1) it might be visually surprising to the
user to see the auto-revert occur; 2) if the user was very hurried to
type at wherever POINT was in the buffer, then the auto-revert would be
further delayed if defcustom `auto-revert-stop-on-user-input' was non-nil
(the default), and would only happen once the hurried typist pauses. In
my anecdotal use / testing / debugging, this has only every happened
when I consciously made the effort to race the auto-revert, but the
experience of a caffeinated or adrenaline-d user might be different.

"Visible" is ambiguous in this context. I suggest "not displayed in
any window" instead. Or, better, just "auto-revert only if buffer is
displayed" (which also solved a problem with double negation).

Is the different treatment of GUI and TTY frames necessary here?
Btw, what will be the effect of this option? Suppose some buffer was
not displayed and missed its auto-revert opportunity. Then I switch
to it in some window -- will it appear with stale contents, or will it
auto-revert before being displayed in the window?

The attached proposed patch adds a defcustom and makes a change to two
existing functions in order to allow a user the option to only have
autorevert mode operate on visible buffers. The change to function
'after-find-files' may also fix a bug (or change behavior) in that
sometimes when being prompted to manually revert a buffer that had been
in auto-revert-mode, the auto-revert-mode status would be lost, ie. set
to nil.
Use of this feature:
1) Reduces CPU workload when using autorevert
2) Reduces messages when using `auto-revert-verbose'
Possible disadvantage:
1) When making a buffer visible, it might take as long as
'auto-revert-interval' seconds for any accumulated changes to
auto-revert. The default for that value is five seconds.
