bug#68648: 30.0.50; read-only-mode-hook's are not executed when buffer-read-only is t

[Björn Bidar via Bug reports for GNU Emacs, the Swiss army knife of text editors]

I noticed when opening a file which isn't readable that
read-only-mode-hooks are not executed.

1. (add-hook 'read-only-mode-hook (lambda () (print "foobar")))
2. open file that is read-only
3. foobar should be print but isn't.

That's because read-only-mode is not entered when you visit a write-protected file.  Maybe we should call the hook anyway, I'm not sure.  We don't honor view-read-only either in these cases, for the same reason.

It does look like the mode is entered because when calling
read-only-mode it is disabled.

It does look like the mode is entered because when calling
read-only-mode it is disabled.

That's only a circumstantial evidence.  read-only-mode is a thin
wrapper around buffer-read-only variable, but setting buffer-read-only
directly (which is what we do when you visit a write-protected file)
doesn't invoke the mode function, and thus the mode hook is not run.
For the same reason, the setting of view-read-only is not honored in
the scenario you described.

Stefan & Stefan, any comments or opinions on this issue?  I' debating
whether to do anything (and if so, what) about this, or close this bug
as wontfix.

I agree that it's far from clear that "read-only-mode is not entered".

That's the technical explanation of what happens, but it's not very
satisfactory as a justification for why it should happen.

I don't understand what you're trying to say here:

    emacs --eval '(setq view-read-only t)' -Q /etc/password

does put me in `view-mode`, so the setting of `view-read-only` seems to
be honored.

[ This a bug of my own making, when I decided to replace
  `toggle-read-only` with`read-only-mode`.  ]

I'd be in favor of replacing the `(setq buffer-read-only t)` with
`(read-only-mode 1)`, but it will require other changes: since calling
`read-only-mode` will handle `view-read-only`, it might make for a nice
simplification, but since the code is fairly complex over there, it
might also make things worse.

I agree that it would be nice to clean this up, but since it isn't
easy (which I, of course, noticed as well), I'm not sure it is worth
our while, given that the problem is really minor.  Thus my doubts and
my question.

I think trying to fix the problem if it so minor can take time.
However closing it as won't is not a good idea because of the ambiguity
of semantics here. It's easy to misunderstanding if you don't know.

On second thought, would it be okay to just call the mode hook where
we set buffer-read-only in after-find-file?

It's probably an acceptable middle ground until someone goes through the
trouble of sorting out how to make the code call `read-only-mode`.
Even better if the `run-hooks` is accompanied with a FIXME explaining
that :-)

Makes sense to me.

Now done on master, let's see what this breaks.

Closing.
