Hi,
I run M-x find-dired and get a dired buffer. When I delete any file in
that buffer, the file's line is not removed from the buffer. This is
sometimes a bit annoying (and not really useful I guess?). Dunno what
other kinds of dired buffers and file actions are also affected.
One aspect of the issue is that `dired-fun-in-all-buffers' and
`dired-buffers-for-dir', which the former is based on, only consider
dired buffers in the `dired-buffers' variable, which, AFAICT, doesn't
include such "non-standard" dired buffers. I also dunno whether looking
in the buffer's `dired-subdir-alist' would be sufficient in my case.
OTOH, when I delete a file in a buffer, dired could be smart enough to
guess that the current buffer does include the file.
TIA,
Michael.

FWIW, I don't understand the last paragraph. What do
you mean by "delete a file in a buffer"? Do you mean
somehow delete a file (from disk) from a buffer that
is visiting it? Or delete it from a Dired buffer?
I'm guessing it's the latter, but in that case Dired
does do that, doesn't it?
For the rest, here's something to maybe consider:
`find-dired' gives you a snapshot of what's on disk
at a given time. Dired does that too, but for Dired
there's an optional behavior of having its display
auto-revert, to pick up any disk changes when you
revisit the Dired buffer.
Is that what you're requesting for `find-dired' too?
If so, should it be turned on by the same option,
`dired-auto-revert-buffer'? I can think that someone
might well want a different option for it.
I can also think that someone might sometimes want
the current behavior, i.e., s?he would turn off such
a new option.
For example, you might want to have a buffer with
such a `find-dired' snapshot, as reference/comparison,
as you go through and delete or modify some of the
listed files, i.e., to keep track of what you've done
so far. (But I guess such tracking would kind of be
available anyway, if you sort the `find-dired' output
by time.)

I hit D in the find-dired result buffer. Dired deletes the file but
it's not removed from the buffer.

No, that's not what I want. That might be very slow, so it's no general
solution. And also not necessary I think.
Michael.

I see. Yes, that sounds like a bug. Thx.

I don't think this is just an issue with dired. I've been noticing it
Emacs-wide. The only exception I've found is that using vterm updates
instantly. But `directory-files' etc. present the same issue.
Happy to debug further and provide more info if desired.
Matt

I think we should individually adress any issues you are seeing in
different parts of Emacs.
Could you please open, for each of these issues, new bug reports with a
recipe for how to reproduce the issues, starting from "emacs -Q"?
Please also state what you see and how this is different from what you
would expect to see.
Best regards,
Stefan Kangas

I think the canonical answer for that is `virtual-dired'.
Michael.
