Johannes,
I completely agree about the E_ERROR - in general. An error should be
recoverable as much as possible. In this concrete case as I've reworking a
patch descending from 2010 and that E_ERROR was there, I just let it go.
The situation is that doing an E_WARNING possibly leaves user with an
invalid object, which will crash on arbitrary places - in method calls,
var_dump or iterator. In 5.5 it is even possible to throw exception in
__wakeup as unserialize cares about it there. But anyway - any recoverable
error would need even more intervention into that code which could
consequently bring further behavior changes.
For #53437 as workaround maybe one could initialize the objects in
DatePeriod (as there are multiple) to some freezed value and put a
warning? That would be more permissive and bring minimal behavior changes.
I could give it a try if you mean it's acceptable. Any solution is better
than a PHP crash I mean :)
Other workaround you've possibly in mind?
Regards
Anatol
