* bug#64023: 29.0.91; gnus-icalendar does not update timestamp when description is empty

I use mu4e for my email and org-mode for managing my calendar.

When I accept a calendar invitation that has *no description* using
gnus-icalendar, and later I receive an update for that invitation, the
code that updates the corresponding org element will remove the
timestamp completely.

This is quite common for invitations from e.g. thunderbird, that have
only a summary but where the description field has been left empty.

To show this in action we would need a complete mu4e and gnus-icalendar
setup, but we can recreate the effect as follows:

we have an org file in "~/test.org" containing an event exported from an
icalendar invitation:

----- contents of test.org -----
* Test
:PROPERTIES:
:ICAL_EVENT: t
:ID:       xxx-11-yyy
:ORGANIZER: Me
:LOCATION:
:PARTICIPATION_TYPE: non-participant
:REQ_PARTICIPANTS:
:OPT_PARTICIPANTS:
:RRULE:
:REPLY:    Not replied yet
:END:

  <2023-08-01 01:00-01:00>
----- end of test.org -----

We can now call the function to update this event to a new date as
follows (this works with emacs -Q):


(require 'gnus-icalendar)
(let ((ev (gnus-icalendar-event :organizer "Me" :summary "Test"
                                :start-time (encode-time '(0 0 0 1 9 2023 nil nil nil))
                                :end-time (encode-time '(0 0 0 1 9 2023 nil nil nil))
                                :uid "xxx-11-yyy"
                                :recur nil
                                :description nil)))
  (gnus-icalendar--update-org-event ev nil (list (expand-file-name "~/test.org"))))

This results in the following:

----- new contents of test.org -----
* [#C] Test ()
:PROPERTIES:
:ICAL_EVENT: t
:ID:       xxx-11-yyy
:ORGANIZER: Me
:PARTICIPATION_TYPE: non-participant
:REPLY:    Not replied yet
:END:
----- end of test.org -----

Note how the timestamp has not been updated but completely erased.

This is because in gnus-icalendar--update-org-event, the code for
updating the timestamp is inside "(when description ...)", causing it to
only be run when the description is not empty.

I was sure Iʼd fixed this already, but that was in `gnus-icalendar-event->org-entry', not
`gnus-icalendar--update-org-event'

How does this work for you:

OK. Eli, emacs-29 or master? Itʼs a pretty small change, but itʼs not
a regression as such.

It looks like a bug. I canʼt find any code creating such a property,
the current code inserts the timestamp in the body of the org entry.

It would be nice to have a separate bug so we can track the change.

    Reindert-Jan> I would also like to try and write the fix for this, if you don't mind.

I never say no to other people writing patches 😺 Thereʼs lots of
useful info in CONTRIBUTE in the emacs sources about code and commit
message conventions.

    Reindert-Jan> Alternatively gnus-icalendar--update-org-event could update the entry to
    Reindert-Jan> include the word "cancelled" in the summary and deactivate the

Deactivating the timestamp is what the current code attempts to do, I
think thatʼs a less surprising change than removing the entry.

As a little exercise I've been writing some unit tests for the bug you
fixed regarding updates to events with empty description. Patch is
attached. Looking forward to any feedback.
