23.0.60; eval-buffer on a file containing help-xref-button doesn't update help mode text |
|

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Do the following to reproduce:
1. Invoke emacs with -q.
2. C-h f help-xref-button
3. Verify that you see a help mode buffer with this text:
> help-xref-button is a Lisp function in `help-mode.el'.
>
> (help-xref-button match-number type &rest args)
>
> Make a hyperlink for cross-reference text previously matched.
> match-number is the subexpression of interest in the last matched
> regexp. type is the type of button to use. Any remaining arguments are
> passed to the button's help-function when it is invoked.
> See `help-make-xrefs'.
>
> [back]
4. Hit the TAB key in that buffer to position over help-mode.el
5. Hit the return key. At this point, you should be in the file
.../share/emacs/23.0.60/lisp/help-mode.el.gz or some similarly named
.el.gz file.
6. Copy the full defun body of the help-xref-button function and paste
it into a new file, say, in /tmp/newfile.el
7. When in the buffer for newfile.el, type M-x eval-buffer
8. Redo step 2 and 3, but notice that the Lisp function in
`help-mode.el' still remains just that. It should instead read
`newfile.el'. Clicking on the link for `help-mode.el' brings me back
to the original definition, not the one I have redefined in newfile.el
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/home/brentg/emacs_from_source/install/share/emacs/23.0.60/etc/DEBUG for
instructions.

Sigh. Now I can't either. And I believe I had saved the file. I had
tried this a number of ways, too. Hmmm, I guess just close/ignore this
for now. Thanks for trying to reproduce it.
