Subject: 28.0.60; curly quote in lisp form in docstrings
Date: Sat, 2 Oct 2021 15:14:54 +0100

emacs -Q
C-h f show-paren-mode

Here, I see (among other things):

-- begin quotation --

To check whether the minor mode is enabled in the current buffer,
evaluate ‘(default-value ’show-paren-mode)’.

-- end quotation --

The straight quote inside the form has become curly (unless gmail has
mangled it), preventing evaluation. This part of the docstring comes
from a template in
easy-mmode.el, so versions of it appear everywhere.

Thanks,

David.

P.S. Not using nativecomp, in case that's relevant.

Yup, this should now be fixed in Emacs 28 (but requires recompiling all
files that use easy-mmode).

I 'touch'ed all the *.el files that use define-minor-mode, but then
rebuilding Emacs with native-compilation fails with error messages
that complain about frame-XXX.eln:

    ELC+ELN  ../lisp/international/mule-cmds.elc
  emacs: can't find function "F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_41" in compilation unit d:\gnu\git\emacs\native-comp\src\../native-lisp/28.0.60-bc5f6bd2/preloaded/frame-b40fc590-734bdcac.eln
  Makefile:286: recipe for target `../lisp/international/mule-cmds.elc' failed

I saw others report similar problems recently.

I worked around this by removing emacs and bootstrap-emacs executables
(and the corresponding pdmp files), which causes a re-dump.

There were no such problems in the build without native-compilation.

frame.el was one of the 'touch'ed files, so it was recompiled, and it
sounds like the problem is with some discrepancy between the old
frame-XXX.eln file with which emacs was dumped, and the new one?  And
it's somehow triggered by refreshing the preloaded *.eln files that
were meanwhile recompiled?

Andrea, what do these error messages mean, and how to avoid them in
the future?  Do we lack some cleanup or some prerequisites in our
Makefile's?

All looks well here after a bootstrap -- thank you very much for the
quick fix, Lars.

David.
