Tyson Andre	241bd3f454	Fix use after free when WeakMap is modified during field write ... (When a value's destructor triggers a resizing or rehashing of the WeakMap) Closes GH-7671	2021-11-20 16:52:25 -05:00

Nikita Popov	614c0b846e	Allow removing non-existing key from WeakMap ... In line with usual PHP semantics. This previously triggered an assertion failure.	2020-08-27 12:42:08 +02:00
Nikita Popov	0026d8a783	Fix use-after-free is WeakMap key and value are the same ... Drop the object from the WeakMap as the last step, as this might end up destroying the object.	2020-08-27 12:05:06 +02:00

Nikita Popov	653e4ea1c5	Add flag to forbid dynamic property creation on internal classes ... While performing resource -> object migrations, we're adding defensive classes that are final, non-serializable and non-clonable (unless they are, of course). This path adds a ZEND_ACC_NO_DYNAMIC_PROPERTIES flag, that also forbids the creation of dynamic properties on these objects. This is a subset of #3931 and targeted at internal usage only (though may be extended to userland at some point in the future). It's already possible to achieve this (what the removed WeakRef/WeakMap code does), but there's some caveats: First, this simple approach is only possible if the class has no declared properties, otherwise it's necessary to special-case those properties. Second, it's easy to make it overly strict, e.g. by forbidding isset($obj->prop) as well. And finally, it requires a lot of boilerplate code for each class. Closes GH-5572.	2020-06-24 11:52:36 +02:00
