Emacs 29.1, org-agenda and SCHEDULED entries

Emacs 29.1, org-agenda and SCHEDULED entries

[Christian Barthel]

Hi,

while upgrading from emacs 28.1 to 29.1, my org-agenda stopped working.
The message in the echo area was:

--8<---------------cut here---------------start------------->8---
    Search failed: "\\<SCHEDULED: *<\\([^>]+\\)>"
--8<---------------cut here---------------end--------------->8---

The search seemed to fail in an old org file:

--8<---------------cut here---------------start------------->8---
  * someentry
    SCHEDULED: [2017-12-12 Tue 17:42]
--8<---------------cut here---------------end--------------->8---

Not sure why I've used an inactive timestamp there but it shouldn't
be a problem I guess?

As a workaround, I have updated the `org-schedule-time-regexp` to
match the brackets as well:

--8<---------------cut here---------------start------------->8---
(setq org-scheduled-time-regexp
  (concat "\\<" org-scheduled-string " *[[<]\\([^]>]+\\)[]>]"))
--8<---------------cut here---------------end--------------->8---

With that new regexp, my agenda loads again without errors but
I do wonder:


Was/Is that change on purpose? (I haven't seen anything in the
ChangeLog)

It is exactly the problem.
Inactive timestamps are not allowed in SCHEDULED/DEADLINE.

Only internals changed. Previously, agenda used a dumb regexp search
using this failing regexp (and skipped your problematic entry
completely). Now, we first query parser cache, which considers your
"someentry" as :scheduled. But agenda expects scheduled items to use
active timestamps all the time, causing the error.

We should update the parser to treat such malformed SCHEDULED/DEADLINE
lines as ordinary paragraphs and report them in org-lint.

I went another way, without changing the existing syntax.

org-agenda will now ignore scheduled/deadline with inactive timestamps,
as it did in the past.
org-lint now has a checker that will report such scenarios.
Fixed, on main.
