Previously, code such as subclasses of SplFixedArray would check for method
overrides when instantiating the objects.
This optimization was mentioned as a followup to GH-6552
If the initializing assignment is an array append we will go through
the UNDEF codepath of get_property_ptr_ptr, which did not verify
that the initialization scope is valid.
When running without opcache, static_members_table is shared with
default_static_members_table. This is visible in reflection output,
because ReflectionProperty::getDefaultValue() will return the
current value, rather than the default value.
Address this by never sharing the table, which matches the behavior
we already see under opcache.
Fixes bug #80821.
Closes GH-7299.
Convert zend_hash_find_ex(..., 1) to zend_hash_find_known_hash(...)
Convert zend_hash_find_ex(..., 0) to zend_hash_find(...)
Also add serializable changes to UPGRADING.INTERNALS summary
Add support for readonly properties, for which only a single
initializing assignment from the declaring scope is allowed.

Closes GH-7089.
We partially fixed this in bug #78379, but still don't handle
the case where the properties array is marked as grey first,
which causes a delref to not be performed later.
Fix this by treating the object properties HT the same way as
other refcounted values, including addrefs/delrefs. The object
dtor code already handles properties HT with NULL GC type, so
out of order destruction should not be a problem.
Fixes oss-fuzz #36023.
Static trait members may only be accessed through a class in which
the trait is used, not directly on the trait.
A complication here is that we should not store static
methods/properties for which a deprecation is triggered in a
cache slot. As the check for this is simple and cheap, I'm handling
this in the cache slot population code in the VM. The alternative
would be to pass the cache slot down into the fetching code.

The analysis in the bug report wasn't correct (at least not in
this case -- there may still be a more general problem here),
the issue was that write_property returned the original variable_ptr
rather than the zend_assign_to_variable() return value, which will
DEREF the variable before overwriting it.
Only reset the uninitialized property flag once the type check
has succeeded. Previously the property was treated as unset rather
than uninitialized after a failed assignment.
Noticed this edge-case while working on accessors...

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
The "member" string here does not necessarily have a pre-calculated
hash value. In particular this is not the case if the class has no
properties.
Fixes oss-fuzz #25546.
This can happen if zend_call_function inserted a dummy frame,
and we already switched to the dummy frame in leave_helper,
and an exception is thrown during CV destruction.
Fixes oss-fuzz #25343.
If we're accessing an uninitialized typed property and __get is
defined, don't perform a read_property callback, as __get is
supposed to have no effect on uninitialized typed properties.
Usually it doesn't, but by-reference assignments cannot be
performed through read_property.
I'm deleting the test for bug #80039 again, as it doesn't really
make sense anymore with this fix.
