Description David Edmundson 2017-11-07 23:39:54 UTC

Steps to reproduce:
Set groupingAppIdBlacklist=firefox.desktop
Open two firefox windows
restart plasma
Crashes

goes away when I remove the config line, happens reliably when I re-add it.

It looks to me like we're killing a delegate mid-way through instantiating it.

Comment 1 Eike Hein 2017-11-13 13:21:57 UTC

Git commit b40c0de099fc951dbe3423b99310e7c7f799c8c4 by Eike Hein.
Committed on 13/11/2017 at 13:21.
Pushed by hein into branch 'master'.

When used by QML, only populate after component is complete

Summary:
This introduces the use of QQmlParserStatus to delay populating
the model until all properties have been set, to avoid delegate
churn.

TasksModel is also meant to be used by C++. There's no good way
to determine whether an object is being instanciated by QML
during construction time, therefore this patch also introduces a
delay in initial population of the model after construction via
a single-shot timer. At the time the slot is invoked we know if
we're used by QML (because QQmlParserStatus::classBegin has
either been called or not by then) so we can decide to populate
or wait more for QQmlParserStatus::componentComplete.

I'm not super happy with this behavior change for C++ users,
however as the model is usually used via QML currently, it's
pragmatic to optimize performance for the common case, and it
doesn't technically break QAbstractItemModel semantics, as model
population isn't required to be sync.

There's a decent change this fixes a recently-reported crash as a
by-product:

Phabricator comment says this commit fixes the issue, but it was (intentionally?) only CC'd, so got not closed automatically.

Please clarify, either by changing the bug status, or by adding a comment what still needs to be done to resolve this ticket.

Comment 3 Eike Hein 2017-11-24 08:01:31 UTC

It's waiting on David to re-test.

Comment 4 David Edmundson 2017-12-06 19:55:11 UTC

Lets assume so. 

I'll reopen if I see it again
