bug#60233: 30.0.50; Dired buffer not updating sometimes

bug#60233: 30.0.50; Dired buffer not updating sometimes

[Jean Louis]

Here is what happens sometimes:
https://gnu.support/images/tmp/2022-12-21/2022-12-21-08:09:15.ogv

- Using d to delete in Dired, also sometimes does not update the Dired
  buffer

- Using b byte compile does what is shown on video

- killing the non-updating Dired buffer and opening new one in the
  same directory solves the problem

- I cannot reproduce with emacs -Q 

- what I know this is happening for long time, more than a year

- I guess that problem lies somewhere in refresh function being missed
  to be executed for some reason

- as additional possible info, my computer "sleeps" sometimes

bug#60233: 30.0.50; Dired buffer not updating sometimes

I cannot watch this.  Would you please back up any images with textual
descriptions of what do you do and what happens?

We'd need a reproducible recipe to investigate.

Which is what?

Some problems with updates to Dired buffers when files or directories
are deleted were fixed about 3 months ago.  So if these problems
happen for much longer, either they are different problems, or you
have stale dired*.el files lurking somewhere that Emacs picks up.

Thanks, but if this is all the information you can provide, I don't
see how we could investigate something that happens only sometimes and
only in your configuration.  I can only hope someone else will report
the missing details.

It creates new file, it does insert the file in Dired buffer, but the
file is double to previous one. It starts appearing as following:

  -rw-r--r-- 1  22K Dec 21 09:54 rcd-org-export.el
  -rw-r--r-- 1  22K Dec 21 21:50 rcd-org-export.elc

That is problem, I can't know when and why is that happening. It is
probably not related to byte compile. I have observed this for a year
or longer.

I use latest from git.

I also use dired-x

and I use switches:

-gohl --group-directories-first

Tell me directions on how to find what is happening the next time it
happens.

Just by pressing B?  I cannot reproduce this here.  Please tell how to
reproduce in "emacs -Q".  (Btw, byte-compile-file is not bound to b,
it is bound to B, upper-case, at least by default.)  What I see is
that after the compilation finishes, Dired moves to the line of the
.elc file just compiled, and the entry is refreshed.

> I also use dired-x

How?

Tried that, still cannot reproduce.

Type "C-h l" and post everything that pops up in a buffer, I guess.
I'm really in the dark here.  You need to try to note what you were
doing that is somewhat special in those cases.

Yes, it was my mistake when writing bug report.

I just load that library every time, as I use it's functions.

OK I am sure it will come again, then I will use C-h l and report back.

bug#60233: 30.0.50; Dired buffer not updating sometimes

I see this on the modeline of your video:

[[[[(Dired by name Launch Hypb WK)]]]]

Unless you customized your modeline in a strange way, these four "[[[[" 
and "]]]]" mean that you're in recursive edit, in a recursive edit, in a 
recursive edit, in a recursive edit (yes, four times).  Is that really 
what you want?

(info "(emacs)Recursive Edit") says: "You could probably do all the rest 
of your editing inside the recursive edit, visiting files and all.  But 
this could have surprising effects (such as stack overflow) from time to 
time.  So remember to exit or abort the recursive edit when you no longer 
need it. In general, we try to minimize the use of recursive editing 
levels in GNU Emacs."

I got now the buffer that does not refresh and I can inspect it if you
provide me guidance.

Thanks, you notices something I did not notice. I can't know why and
how that came in the modeline.

I invoke recursive edits all the time, though not related to Dired buffer.

That is definitely some other bug that I will report. I do use
recursive edit, but I see now that after closing recursive edit those
square brackets do not close.

bug#60233: 30.0.50; Dired buffer not updating sometimes

[Jean Louis]

Hello Eli,

Now I can reproduce the bug "why Dired buffer does not update" with
`emacs -Q'.

The new video for those who can see it is here: 
https://gnu.support/images/tmp/2022-12-23/2022-12-23-07:56:46.ogv

Conditions that Dired buffer will not update is related to default
directory being changed, being something else than what is the Dired
buffer. 

To reproduce it in `emacs -Q' you please do following:

- go into any Dired buffer;

- M-x cd RET and change default directory to something else than Dired
  buffer

- key B will inject new lines of a byte-compiled file without
  refreshing, delete by moving to Trash will delete without refreshing
  the Dired buffer.

I can only assume that variable `default-directory' shall remain local
to Dired buffer even if user invokes `M-x cd' or programmatically `cd'.

And I never invoke `M-x cd' in Dired buffers, but I may invoke it in
other functions such as below:

(defun cf-send-sms (id)
  "Sends the SMS by using default SMS function"
  (cd (getenv "HOME"))

And the reason to `cd' to HOME directory is to escape programs to try
external commands within Tramp directories. I will try using
`executable-find' for external programs, but again I think that when
my functions get Tramp directory as default directory then they don't
find either executables or directories, that is why I am changing to
$HOME.

For Dired updating, I think that M-x cd shall not change the
default-directory for Dired buffer -- and again -- I am not using it
interactively but in functions.

Now I can't remember how I invoked a function that uses `cd' but I can
focus on it next time. Maybe I just launched some of functions.

You're better with

--8<---------------cut here---------------start------------->8---
(defun cf-send-sms (id)
  "Sends the SMS by using default SMS function"
  (let ((default-directory (getenv "HOME")))
    ...)

It's also possible that you get errors, which pop up the debugger and
enter recursive-edit, and you don't abort recursive-edit with C-]
after that.

I get it, I will use that.

Thanks.

I think there's a misunderstanding here of what "M-x cd" does.  Its
_only_ effect is to change the default-directory of the current
buffer.  So:

  (1) doing this in a Dired buffer is shooting yourself in the foot;
  (2) if 'cd' is not allowed to change default-directory in Dired
      buffers, then it will have no effect, which sounds unjustified
      and unnecessary;
  (3) whatever you think you need "M-x cd" for in Dired buffers must
      be done in some other way

I don't think I see any bug here.  It's a cockpit error: you should
not invoke "M-x cd" in Dired buffers if you want to keep updating
them.

Alright. I have changed the program by Michael's advise.

I'm therefore closing the bug.
