diary in emacs 21.2

diary in emacs 21.2

[Victor S. Miller]

I've been using the emacs calendar and diary for many years, without
much problem.  Recently, the linux systems where I work have been
upgraded so that the version of emacs used there is 21.2.  Now,
whenever I invoke calendar (I use Fancy diary entries), it craps out
after displaying the calendar with a message saying "Calendar buffer
is read only".  If I type 'd' (to get the diary display) I get the
same message.  Things work fine when I use emacs 20.7 (which are on
some other systems).  Strangely when I set debug-on-error to 't, it
does NOT give me an error traceback at all.  Does this sound like a
known bug in 21.2?

some questions, which could help you to help yourself:

  do you start your emacs-21 session with the old emacs-20 init file ?

  what do your (old ?) init file or (new !) site-lisp directories
  contain, which could be relevant to diary and calendar ?

  did you try to start your emacs-21 session with the options
  --no-init-file --no-site-file and then set up  your calendar/diary
  step by step from scratch ?

have a look at a file named NEWS (in the etc directory of the emacs-21
tree ?) for 20->21 changes of diary and calendar.

Not in the calendar/diary code.  Since I don't use a Linux system, can
somebody help debug this?

Well, some errors do not enter the debugger.  Set debug-ignored-errors
to nil for maximum debugging.  Furthermore, try it in Emacs with -q
and --no-site-file -- perhaps you have code on a hook that tries to
modify the calendar after display?

I run GNU Emacs 21.2.90.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll
bars) of 2002-05-28 on confusibombus, just created a diary file, added
an entry, used (setq diary-display-hook '(fancy-diary-display)), used
m to update the calendar, saw the marked entry, pressed d on the day,
and got a fancy diary buffer with my test entry.  "It works for me."
