bug#58286: 29.0.50; (dired-toggle-read-only) should verify if file names changed

[Jean Louis]

I have noticed that C-x C-q does not verify if file names changed.

If file name was:

my-file.ext.part

once C-x C-q is invoked, it does not refresh buffer. In my opinion it
shall refresh buffer or warn that file name does not exist any more, if
it does not, so that editing of file names makes sense.

I don't understand what you mean here -- editing file names in wdired
works fine for me.

Do you have a step-by-step recipe, starting from "emacs -Q", that
demonstrates the problem?

It is explained above. The file my-file.ext.part was edited, but then
at some point the file named changed during editing, or file may be
removed. After editing, the buffer was not refreshed. I could see new
file name in the buffer while that file did not exist.

With emacs -Q I see that it refreshes.

I can't understand why and how, that is what happened. I do not change
dired myself in anyway, even if not used with emacs -Q.

That's still not a step-by-step recipe -- I don't understand what you
say you've done, or what you're seeing.

If the case is that you can't repeat the problem, but that it was
something odd that happened once, but you don't know how or why, then I
don't think we're going to get any further here.
