Fix static variable behavior with inheritance When a method is inherited, the static variables will now always use the initial values, rather than the values at the time of inheritance. As such, behavior no longer depends on whether inheritance happens before or after a method has been called. This is implemented by always keeping static_variables as the original values, and static_variables_ptr as the modified copy. Closes GH-6705.

Added Inheritance Cache. This is a new transparent technology that eliminates overhead of PHP class inheritance. PHP classes are compiled and cached (by opcahce) separately, however their "linking" was done at run-time - on each request. The process of "linking" may involve a number of compatibility checks and borrowing methods/properties/constants form parent and traits. This takes significant time, but the result is the same on each request. Inheritance Cache performs "linking" for unique set of all the depending classes (parent, interfaces, traits, property types, method types involved into compatibility checks) once and stores result in opcache shared memory. As a part of the this patch, I removed limitations for immutable classes (unresolved constants, typed properties and covariant type checks). So now all classes stored in opcache are "immutable". They may be lazily loaded into process memory, if necessary, but this usually occurs just once (on first linking). The patch shows 8% improvement on Symphony "Hello World" app.

Use zend_type inside type lists Instead of having a completely independent encoding for type list entries. This is going to use more memory, but I'm not particularly concerned about that, as type unions that contain multiple classes should be uncommon. On the other hand, this allows us to treat top-level types and types inside lists mostly the same. A new ZEND_TYPE_FOREACH macros allows to transparently treat list and non-list types the same way. I'm not using it everywhere it could be used for now, just the places that seemed most obvious. Of course, this will make any future type system changes much simpler, as it will not be necessary to duplicate all logic two times.

Introduce extra counter to avoid RTD key collisions Also generate a fatal error if a collision occurs in zend_compile. This is not perfect, because collisions might still be introduced via opcache, if one file is included multiple times during a request, invalidate in the meantime and recompiled by different processes. This still needs to be addressed, but this patch fixes the much more common case of collisions occuring when opcache is not used. Fixes bug #78903.

Implement union types According to RFC: https://wiki.php.net/rfc/union_types_v2 The type representation now makes use of both the pointer payload and the type mask at the same time. Additionall, zend_type_list is introduced as a new kind of pointer payload, which is used to store multiple class types. Each of the class types is a tagged pointer, which may be either a class name or class entry. The latter is only used for typed properties, while arguments/returns will instead use cache slots. A type list can contain a mix of both names and CEs at the same time, as not all classes may be resolvable. One thing this is missing is support for union types in arginfo and stubs, which I want to handle separately. I've also dropped the special object code from the JIT implementation for now -- I plan to add this back in a different form at a later time. For now I did not want to include non-trivial JIT changes together with large functional changes. Another possible piece of follow-up work is to implement "iterable" as an internal alias for "array|Traversable". I believe this will eliminate quite a few special-cases that had to be implemented. Closes GH-4838.

Make zend_type a 2-field struct We now store the pointer payload and the type mask separately. This is in preparation for union types, where we will be using both at the same time. To avoid increasing the size of arginfo structures, the pass_by_reference and is_variadic fields are now stored as part of the type_mask (8-bit are reserved for custom use). Different types of pointer payloads are distinguished based on bits in the type_mask.

Fix bug #78226: Don't call __set() on uninitialized typed properties Assigning to an uninitialized typed property will no longer trigger a call to __set(). However, calls to __set() are still triggered if the property is explicitly unset(). This gives us both the behavior people generally expect, and still allows ORMs to do lazy initialization by unsetting properties. For PHP 8, we should fine a way to forbid unsetting of declared properties entirely, and provide a different way to achieve lazy initialization.

Remove legacy AC_CHECK_TYPE calls for uint and ulong The AC_CHECK_TYPE was refactored in more recent versions of Autoconf and the call with two arguments is obsolete and not recommended anymore. This patch also refactors some leftovers of using ulong and uint which are not standard nor common usages of types in C. The ulong can be used as zend_ulong and uint usage is actually `unsigned int`. The usage of HAVE_ULONG removed since it is not used in current code base. Legacy edgecase for some legacy HPUX systems removed: - sys/stream.h header is not checked and the HAVE_SYS_STREAM_H is not defined with current build system. - flags are unsigned int - max_allowed_packet changed to unsigned int
