Bug? org-id-find not finding some IDs

[Jack Kamm <jackkamm@tatersworld.org>]

Hello,

The documentation for org-id-extra-files suggests that org-id-find
should search in Org files visited by Emacs:

> When Org reparses files to remake the list of files and IDs it is
> tracking, it will normally scan the agenda files, the archives
> related to agenda files, ... and any Org file currently visited by
> Emacs.

But, I've found that's not true, or maybe I'm misunderstanding the
doc.

For a minimal example, put the following in test.org:

> * Headline 1
> :PROPERTIES:
> :ID:       b1569c92-3872-4ab9-80eb-274c4950991e
> :END:

Then:

1. emacs -Q test.org
2. C-x b *scratch*
3. M-: (org-id-find "b1569c92-3872-4ab9-80eb-274c4950991e")

Which returns nil. Also, "C-h v org-id-files" doesn't contain
test.org.

Or maybe the docstring for org-id-extra-files should be rewritten to
say "the current buffer" instead of "any Org file currently visited"?

Also, this seems to be the cause of this bug in org-caldav, which is
how I ran into it:
https://github.com/dengste/org-caldav/issues/230

Would there a recommended mitigation for this on org-caldav's side? I'm
thinking it could call

(org-id-update-id-locations org-caldav-files)

early on, to make sure org-caldav-files ends up in org-id-files.
