Hi,

I get an error when I do this, and the content of the buffer is
completely replaced by a single "y".

1. Start with "emacs -Q"
2. M-x delete-selection-mode
3. Open some text file (fundamental mode)
4. Modify the file externally
5. While a selection is active, yank some text
6. Answer yes to the question "<file> changed on disk..."

The content of the buffer is now completely replaced by a single "y".
The message "No catch for tag: exit, nil" is shown in the minibuffer.

I can't reproduce this on Emacs 26.3.

Kind regards,
Lars Ljung

I can confirm that this bug is still present in Emacs 28.

The backtrace is included below, if that helps anybody.

Debugger entered--Lisp error: (no-catch exit nil)
  throw(exit nil)
  exit-minibuffer()
  read-char-from-minibuffer-insert-char()
  funcall-interactively(read-char-from-minibuffer-insert-char)
  call-interactively(read-char-from-minibuffer-insert-char nil nil)
  command-execute(read-char-from-minibuffer-insert-char)

I'm guessing this is some unintended consequence of replacing
read-char-choice in userlock.el with read-char-from-minibuffer.

Juri, could you please look into this regression in Emacs 27?  I'd
like to try to fix this for 27.2.

Thanks.

Here is a brief trace that explains the cause of the problem:

1. C-y (yank) calls delete-selection-pre-hook from pre-command-hook
2. delete-selection-helper calls delete-active-region
3. this activates ask-user-about-supersession-threat on a modified file
4. it calls read-char-from-minibuffer ('this-command' is still 'yank')
5. read-char-from-minibuffer waits when user types 'y'
   (bound to the command 'read-char-from-minibuffer-insert-char')
6. after typing 'y', read-char-from-minibuffer returns 'y', but
   now 'this-command' is 'read-char-from-minibuffer-insert-char'
7. when delete-selection-pre-hook finishes, due to 'this-command'
   'read-char-from-minibuffer-insert-char' is called again,
   and this time operates on the buffer as if it's the minibuffer

It seems there is a fundamental problem when read-from-minibuffer
is used from pre-command-hook it modifies the value of this-command.
But I wonder why this problem doesn't occur in other places.
Maybe other places doesn't try to operate on the buffer as on
the minibuffer?

Anyway, here is a patch with two fixes:
1. Guards read-char-from-minibuffer-insert-char against inadvertent
   operating on the non-minibuffer buffer;
2. Prevents read-char-from-minibuffer from changing the value of
   'this-command' by read-from-minibuffer:

So I pushed the patch to master, and backported it to the emacs-27 branch
(separate commits were needed to avoid merge conflicts).

I suspect this will/would just hide a problem (such as the current one)
under the rug.

Right, but I think that this needs to apply to all recursive edits
rather than only `read-char-from-minibuffer`.

I admit this is a workaround, but I have no idea what would be a proper fix.

I tried to test recursive commands at the read-char-from-minibuffer's
prompt, but can't reproduce the same problem.

The let-binding of `this-command` fixes the problem, doesn't it?

No, I mean other uses of a recursive edit from `pre-command-hook` would
cause the same problem, so the let-binding should be placed deeper than
in `read-char-from-minibuffer`, e.g. inside `recursive_edit_1`.

But might other uses of a recursive edit break it again?
I guess `when (minibufferp)` can't be removed
from `read-char-from-minibuffer-insert-other`
until all cases below are fixed.

I see, so this problem is more general and not specific to
`read-char-from-minibuffer`?  It would be nice to find
a test case for other commands to confirm that a change in
`recursive_edit_1` fixes them.

What do you mean by `it`?

There's only one recursive edit associated with
`read-char-from-minibuffer-insert-char`, so no definitely not that
(unless the user binds (or somehow uses) that command in keymaps used in
other recursive edits, of course).

And AFAICT, the bug see is that `delete-selection-mode` ends up running
a command (originally run inside a recursive edit) a second time.
IOW it's not "recursive edit broke `read-char-from-minibuffer-insert-char`"
but "recursive edit broke `delete-selection-mode`".
This can/will cause problems with loads of commands, not just
`read-char-from-minibuffer-insert-char`.

So yes, other uses of recursive edits can break `delete-selection-mode`
as well, but no amount of changing
`read-char-from-minibuffer-insert-char` will hide the problem because
those other uses will use other commands.

OTOH, the let-binding of `this-command` should fix the problem once and
for all uses of recursive edit *if* it's placed deep enough that it
affects all recursive edits.

I don't see the "cases below" you're referring to.

Exactly.  Any recursive edit happening from the `pre-command-hook`.

Even without trying to reproduce the specific problem that caused this
bug report, think of this scenario:

   - User causes COMMAND to be run.
   - `this-command` is thus set to COMMAND.
   - We run the `pre-command-hook`.
   - One of the functions on `pre-command-hook` use a recursive edit.
   - `this-command` is now set to whichever command was run last in the
     recursive edit, which is just plain wrong.

I remember seeing places in the code where we try and circumvent this
problem, but this bug report makes it clear what is the real source of
the problem.

Thanks for explanations.  I thought it is specific to
`delete-selection-mode` and `read-char-from-minibuffer`.
But since a combination of `pre-command-hook` and a recursive command
is a general problem, and OTOH `read-char-from-minibuffer` is already
safeguarded by the let-binding of `this-command`, so probably
`when (minibufferp)` could be removed from
`read-char-from-minibuffer-insert-other`.

Frankly speaking, I'm afraid of making such change at great depths ;-)
