bug#12833: 24.2.50; Avoid questions asked in the echo area to be overridden by messages

[Sebastien Vauban]

This bug report will be sent to the Bug-GNU-Emacs mailing listand the GNU bug
tracker at debbugs.gnu.org. Please check that the From: line contains a valid
email address. After a delay of up to one day, you should receive an
acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':


Here a recipe to reproduce the symptom explained in
http://lists.gnu.org/archive/html/help-gnu-emacs/2012-04/msg00014.html

1. Take the following minimal Emacs file:

--8<---------------cut here---------------start------------->8---
   ;; "source" of the problem
   (defadvice require (around require-around)
     "Leave a trace of packages being loaded."
     (let* ((feature (ad-get-arg 0)))
       (cond ((featurep feature)
              (message "(info) Requiring `%s'... already loaded" feature)
              (setq ad-return-value feature))
             (t
              (let ((my/time-start))
                (message "(info) Requiring `%s'..." feature)
                (setq my/time-start (float-time))
                ad-do-it
                (message "(info) Requiring `%s'... %s (loaded in %.2f s)"
                         feature
                         (locate-library (symbol-name feature))
                         (- (float-time) my/time-start)))))))

   (ad-activate 'require)
--8<---------------cut here---------------end--------------->8---

2. Load the minimal Emacs.

3. Create a new file.

4. Apply org-mode on it (M-x org-mode). You see the information from the
   defadvice: every require'd package gets tracing info (from where, in how
   much time).

5. Create a headline with M-RET

6. Schedule a date from that item with `C-c C-s': the prompt for the date gets
   hidden (for something like 5 seconds) by the "require" message (though,
   that happened before displaying the prompt).

This is reproducible ever and ever, in the same session.

For the sake of clarity, please find a screencast of the problem:
   http://screencast.com/t/fmmkKf3CJ


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file

It shouldn't be 5 seconds, but more like 2 seconds (or rather "whatever
time it takes to display the messages plus setup the minibuffer plus 2s").

IOW this is `minibuffer-message-timeout'.

What behavior would you like to see instead?

Not speaking for the op, but I would like that messages only went to *Messages* and was never shown in the minibuffer if there is a prompt there.

Semantic/CEDET is a pain to use because of this with its useless "parsing..." messages.

Just checked that unknown var (for me): yep, equals 2. The true reality (now
that I'm chronometering it) is as well that the messages are more or less
displayed for 2 seconds -- but they seemed like 5 looong seconds.

> What behavior would you like to see instead?

IIUC, the require (of some package) is done before asking whatever question in
the minibuffer. So, for me, the same would apply as in other cases...

    If I do 2 requires in a row (package "A", then package "B"), the message
    telling I required the first one ("A") will certainly not be visible in
    the echo area, as immediately after, there is another message being
    displayed, saying that "B" just got required.

What does that change in case of interactive question?

    If I do 1 require before asking a question to the user, the message about
    that require should hardly be visible (if visible at all -- because
    actions happen so quickly). The question should use the space of the
    information message, point.

In the given example here above, things are happening in the function
`org-read-date':

--8<---------------cut here---------------start------------->8---
(defun org-read-date (...)
  "Read a date..."
  (require 'parse-time)
  ...
  (read-string prompt default-input 'org-read-date-history timestr)
  ...)
--8<---------------cut here---------------end--------------->8---

The require of `parse-time' does display a message in the minibuffer (echo
area, to be accurate). When executing `read-string', whatever displayed
message should disappear and be replaced by the prompt.

The prompt, IMO, should never be overridden by a reminiscent message.

Am I exposing clearly my point of view (be it shared or not)?

Best regards,
  Seb

I see, yes, that would make sense.

Does that mean it will be fixed that way?

BTW, I tested a workaround in the meanwhile: let-binding
`minibuffer-message-timeout' to 0.

--8<---------------cut here---------------start------------->8---
       (defadvice require (around require-around)
         "Leave a trace of packages being loaded."
         (let* ((feature (ad-get-arg 0))
                (require-depth (or (and (boundp 'require-depth) require-depth)
                                   0))
                (prefix (concat (make-string (* 2 require-depth) ? ) "+-> "))
                (minibuffer-message-timeout 0))
           (cond ((featurep feature)
                  (message "(info) %sRequiring `%s'... already loaded"
                           prefix feature)
                  (setq ad-return-value feature))
                 (t
                  (let ((lvn/time-start))
                    (message "(info) %sRequiring `%s'..." prefix feature)
                    (setq lvn/time-start (float-time))
                    (let ((require-depth (1+ require-depth)))
                      ad-do-it)
                    (message "(info) %sRequiring `%s'... %s (loaded in %.2f s)"
                             prefix feature
                             (locate-library (symbol-name feature))
                             (- (float-time) lvn/time-start)))))))

       (ad-activate 'require))
--8<---------------cut here---------------end--------------->8---

However, that does not work: questions are still overridden for 2 seconds by
old messages.

Setting it globally, in my .emacs, to 0 does well work.

Am I missing something?

Best regards,
  Seb

No, it just means that I'd accept such a change.  But I don't have time
to come up with a patch for it in the foreseeable future.

I think you'd need to let-bind it around the code that brings up
the minibuffer.

IIUC, in the examplified case, you mean to let-bind it in defun
`org-read-date'?

But that is only one case out of hundreds: the problem appears as well in many
other functions of many other packages (than Org): `describe-variable', and
`describe-function', just to name a few.

In fact, IIUC, it happens every time that a defun embeds a `require' and a
user interaction via the minibuffer.

All those packages (`org.el', `help-fns.el', etc.) are out of my
responsability area. I can't path them all, can I?

  Seb

That's one option, yes, tho doing it lower down the stack might help
make it work in more places.  E.g. you can try advising read-from-minibuffer.

These are just workarounds.  A real fix would need to be somewhere
probably in the C code, maybe in read-from-minibuffer.

Right!

I added the following (IIUC) to my .emacs file:

--8<---------------cut here---------------start------------->8---
  (defadvice read-from-minibuffer (around read-around)
    "Read ... ."
    (let* ((minibuffer-message-timeout 0))
      ad-do-it))

  (ad-activate 'read-from-minibuffer)
--8<---------------cut here---------------end--------------->8---

Sadly, it did not provide me with a workaround to the problem... User input is
still overridden by reminiscent messages.

  Seb

Maybe a more radical

  (defadvice read-from-minibuffer (before crush-message activate)
    (message nil))

will do

Thanks for the tip!  However, no, it did not change anything...

My guess is that the advice is not run, then.  Probably because the
minibuffer is setup via completing-read which is coded in C and calls
Fread_from_minibuffer directly, thus bypassing advice.

You can try adding

   (defadvice completing-read (before crush-message activate)
     (message nil))

[ tho Fcompleting_read is also called a few times from the C code, so
  that advice will also be bypassed in various occasions.  ]

Thanks again...

I now have added this to my .emacs:

--8<---------------cut here---------------start------------->8---
(defadvice read-from-minibuffer (before crush-message activate)
  (message nil))

(defadvice completing-read (before crush-message activate)
  (message nil))
--8<---------------cut here---------------end--------------->8---

However, that still does not solve this override problem...

  Seb

I think this was fixed some months ago -- messages are appended to
prompts now (in Emacs 28, at least).  So I'm closing this bug report.
If there's still more to be done in this area, please respond to the
debbugs address and we'll reopen.
