If a page inlines some other page (such as this page by the bugs page),
and the page is removed (such as by this page being linked to bugs/done),
the inlining page is not updated to remove it.
This only happens if the page is removed from the inlined pagespec due to
a tag changing; the problem is that once the tag is changed, ikiwiki does
not know that the page used to match before.
Another example would be a pagespec that allowed only matching new pages:
newer(1 day)
Obviously, the pages that matches are going to change, and again once they
do, ikiwiki will no longer know that they matched before, so it won't know
to remove them from a page that used that to inline them.
To fix, seems I would need to record the actual list of pages that are
currently included on an inline page, and do a comparison to see if any
have changed.
At first I thought, why not just add them to the dependencies
explicitly, but that failed because the dependencies GlobList failed to match
when a negated expression like "!tag(bugs/done)" is matched. It is,
however, doable with PageSpecs:
(real deps here) or (list of all currently inlined pages here)
However, it's not really clear to me how to _remove_ inlined pages from the
deps when they stop being inlined for whatever reason. So a separate list
would be better.
So this is blocked by [[todo/plugin_data_storage]] I suppose.
