Hi,
I have this code:

|(defun make-search-sensitive-to-ifpmod-advice (orig-fun &rest args) 
"Temporary advice the search functions to make them sensitive to 
`isearch-filter-predicate'" (let ((POINT (point))) (catch 'filtered 
(while (apply orig-fun args) (let ((B (match-beginning 0)) (E (match-end 
0))) ;; 1 - If all points in the region that matches the search ;; from 
the previous "search-command" meet the criteria ;; accepted by the 
filter, then the loop stops (`throw') and ;; returns the position 
`(point)`: (when (funcall isearch-filter-predicate B E) (throw 'filtered 
(point))))) ;; 2 - If the search is unsuccessful, or does not meet ;; 
the criteria accepted by the filter, then return to the ;; starting 
position and return the value `nil'. (goto-char POINT) nil))) |

|(defalias 'search-forward-ifpmod (symbol-function 'search-forward) 
"Copy of `search-forward' function (to be) adviced to obey to 
`isearch-filter-predicate'") (advice-add 'search-forward-ifpmod :around 
#'make-search-sensitive-to-ifpmod-advice) (defalias 
're-search-forward-ifpmod (symbol-function 're-search-forward) "Copy of 
`re-search-forward' function (to be) adviced to obey to 
`isearch-filter-predicate'") (defalias 'search-forward-regexp-ifpmod 
're-search-forward-ifpmod) ;; The following breaks my minor-modes 
definitions (advice-add 're-search-forward-ifpmod :around 
#'make-search-sensitive-to-ifpmod-advice) |

I found that this particular code snippet:

|(advice-add 're-search-forward-ifpmod :around 
#'make-search-sensitive-to-ifpmod-advice) |

breaks my minor-modes definitions. E.g. if I evaluate the code above and 
later on the following code (MWE):

|(defun mwe-function-1 () "MWE function 1" (interactive) (message 
"function 1 executed")) (define-minor-mode mwe-mode "MWE mode" 
:init-value nil :lighter (:eval (propertize " MWE " 'face '(:foreground 
"RoyalBlue" :background "DarkGoldenrod1"))) :keymap `( (,(kbd 
"<C-kp-1>") . mwe-function) ) (if mwe-mode (easy-menu-define mwe-menu 
mwe-mode-map "MWE" '("MWE mode" ;; I want the menu on mode-line only: 
:visible (not (eq (framep (selected-frame)) 'x)) ["mwe-function-1" 
mwe-function-1 :help "mwe-function 1"] )) t)) |

I get this error:

    internal-macroexpand-for-load: Eager macro-expansion failure:
    (wrong-type-argument integer-or-marker-p nil)


        Step to reproduce the error:

 1. |emacs -Q|
 2. Evalute the |add-advice| code
 3. Evalute my minor-mode definiton

Did I make a mistake in the |add-advice| usage or is it a bug?

Best regards,

Gabriele Nicolardi

Thanks.

I can't find a commit "ac89b1141a26" in my repository, though.  Where
does your Emacs come from (is it maybe a modified version)?

Forget this question please.  I can now reproduce with master, too.

But: This is only reproducible when I build Emacs with native
compilation enabled.  Then I get this backtrace with your recipe:

| Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
|   forward-paragraph(1)
|   fill-forward-paragraph(1)

|   #f(compiled-function (arg1 arg2 &rest rest) "Define a new minor mode MODE....
|   elisp--eval-last-sexp(nil)

When I load the source of paragraphs.el (where `forward-paragraph' is
defined) the problem goes away.

Maybe Andrea can help?  Just CC'd - I don't know how to continue here.

Thx,

Michael.

I confirm that evaluating paragraphs.el makes the problem go away.

But why? I create a copy of the `re-search-forward` function because I 
DON'T want advice the original function:

;; The following breaks my minor-modes definitions (advice-add 
're-search-forward-ifpmod :around #'make-search-sensitive-to-ifpmod-advice)

Why `forward-paragraph` should be sensitive to a function 
`re-search-forward-ifpmod` that it doesn't call?

Is my code wrong in some way?

I mean that I think that

(defalias 're-search-forward-ifpmod (symbol-function 're-search-forward) 
"Copy of `re-search-forward' function (to be) adviced to obey to 
`isearch-filter-predicate'")

should create a COPY, not an ALIAS, of the `re-search-forward` function 
indipendent of the original function.

Anyway, how can I force the loading of paragraphs.el? I don't se the 
"provide" feature and I need to share my code with my teammates.

Stefan, can you help maybe?  Gabriele then does this:

#+begin_src emacs-lisp
(advice-add 're-search-forward-ifpmod
            :around
            #'make-search-sensitive-to-ifpmod-advice)
#+end_src

and we have found that this causes weird errors because at least some
definitions, like `forward-paragraph', call `re-search-forward-ifpmod'
afterwards.  This seems to happen only when using a native compiled
Emacs, and the effect disappears when loading the source - paragraphs.el
in this case.  Is this normal?

Sounds like a problem in the code that installs trampolines.

Andrea?

If we look at `fset`, the C code does:

    if (!NILP (Vnative_comp_enable_subr_trampolines)
        && SUBRP (function)
        && !SUBR_NATIVE_COMPILEDP (function))
      CALLN (Ffuncall, Qcomp_subr_trampoline_install, symbol);

so indeed if the SUBR_NATIVE_COMPILEDP function is stored in another
symbol, we will still call Qcomp_subr_trampoline_install, even tho it's
a case where it should not be necessary, and I suspect this can lead to
the kind of problems mentioned above, if we do something like

    (defalias 'foo (symbol-function 'bar))
    (fset 'foo <something-else>)

where native calls to `bar` could end up redirected to the definition of
`foo` :-(

Here I'm,

mmmhh, I'm really not sure why calling Qcomp_subr_trampoline_install
should be problematic.  I'll look at it, but this week I'm on holiday so
might take a bit more :)

I'm not completely sure either, but the arg of
`comp-subr-trampoline-install` is called `subr-name` whereas the value
we pass there is the symbol that was found to contain that subr but is
*not* the name of the subr (and when that's the case, there's simply no
need to install any trampoline).

So, I'd expect `comp-subr-trampoline-install` to compare its argument
with the actual name of the subr (presumably extracted from the subr),
but I don't see any such test.

Okay I've installed 00553628558 into master, I believe it does what we
want and seems to fix the minimal reproducer I made from the original
example.

Gabriele could you check it solves the issue for you?

Now thinking about, I think we should install it into 29 if it proves to
be the right fix.

Thanks!

I'm sorry, but I'm not sure what to do to test the modification.
I have Emacs 29.2 installed via snap. I suppose I would need to
install the modified version by downloading it from the repo.
This is something I've never done before.
If necessary, I could try doing it on a virtual machine.

This would be desirable since the version provided by snap is indeed 29.

Thanks!

Something like this should do the job (you might need to install some
package):

$ git clone https://git.savannah.gnu.org/git/emacs.git
$ cd emacs && ./autogen.sh && ./configure --with-native-compilation && make -j16

Once done you can run this emacs without installing it with $ ./src/emacs

So if you wanted to use a VM not to install this particular Emacs it
might not be necessary.

Once we are more confident is not causing issues I'll do it.  Maybe we
can revist this in few weeks, hopefully sitting on master we should get
a report if something breaks.

I was not able to build Emacs because of:

configure: error: ELisp native compiler was requested, but libgccjit was 
not found.
Please try installing libgccjit or a similar package.

(I installed libgccjit-10-dev)

If you want a lightweight approximation to the real test, you could add
the following to the beginning of your init file:

    (with-eval-after-load 'comp-run
      (require 'cl-lib)
      (defun comp-subr-trampoline-install (subr-name)
        "Make SUBR-NAME effectively advice-able when called from native code."
        (when (memq subr-name comp-warn-primitives)
          (warn "Redefining `%s' might break native compilation of trampolines."
                subr-name))
        (let ((subr (symbol-function subr-name)))
          (unless (or (not (string= subr-name (subr-name subr))) ;; (bug#69573)
                      (null native-comp-enable-subr-trampolines)
                      (memq subr-name native-comp-never-optimize-functions)
                      (gethash subr-name comp-installed-trampolines-h))
            (cl-assert (subr-primitive-p subr))
            (when-let ((trampoline (or (comp-trampoline-search subr-name)
                                       (comp-trampoline-compile subr-name))))
              (comp--install-trampoline subr-name trampoline))))))

and then try and reproduce the problem.

I'm not sure comp-run is not already loaded when this gets evaluated,
removing "(with-eval-after-load 'comp-run" might do the job?  The real
test would be recompiling tho :)

I confirm that the version compiled from master resolves my issue.

Thank you!

Very cool.  I'll keep this bug open a bit just so we remeber to
re-evaluate the backport.

Thanks!

Okay backported the fix to emacs-29.  I'm closing this.

`load'.  But I think this would only work around one symptom, and I
guess more things are broken by your advice.  Let's first wait for
someone who understands better what's going on, ok?

This is the backtrace in 29.2:

Thanks - I think that's the same problem as my backtrace showed.

My guesses are that either `easy-mmode--mode-docstring's setup of the
temporary buffer it uses for filling the docstring doesn't always suffice,
or there is an interference with nadvice's advices of docstring making
functions (`advice--defalias-fset', `nadvice--make-docstring').

Michael.
