Subject: bug#4887: 23.1; list-load-path-shadows produces broken buffer
Date: Sat, 7 Nov 2009 21:34:54 -0800 [thread overview]
Message-ID: <200911080534.nA85YsTH029113@mailhub-pa1.hpl.hp.com> (raw)
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
* turn on global-linum-mode
* run list-load-path-shadows
* observe that the resulting buffer, *Shadows*, has no line numbering,
even if you change into that buffer, move around, and change text. [BUG]
Some debugging shows that:
*Shadows* has a post-command-hook value (^h v) of nil, when it should
contain (linum-update-current t) locally and
(... global-linum-mode-check-buffers) globally.
Looking at the source code shows that the following code creates the
buffer *Shadows*:
shadows.el:239:
;; Create the *Shadows* buffer and display shadowings there.
(let ((output-buffer (get-buffer-create "*Shadows*")))
(display-buffer output-buffer)
(set-buffer output-buffer)
(erase-buffer)
(while shadows
(insert (format "%s hides %s\n" (car shadows)
(car (cdr shadows))))
(setq shadows (cdr (cdr shadows))))
(insert msg "\n")))
Some experimentation shows that the offending code is:
(get-buffer-create "*Shadows*")
If you just run this via eval-expression, a new buffer called *Shadows*
is created with a broken value of post-command-hook. I do not appear to
have source code for this function, so I leave the rest of the debugging
job to you...
