* Deprecate passing null to non-nullable arg of internal functionNikita Popov2021-02-111-51/+51
| | | | | | | | | | | | | | | | | | | | | This deprecates passing null to non-nullable scale arguments of internal functions, with the eventual goal of making the behavior consistent with userland functions, where null is never accepted for non-nullable arguments. This change is expected to cause quite a lot of fallout. In most cases, calling code should be adjusted to avoid passing null. In some cases, PHP should be adjusted to make some function arguments nullable. I have already fixed a number of functions before landing this, but feel free to file a bug if you encounter a function that doesn't accept null, but probably should. (The rule of thumb for this to be applicable is that the function must have special behavior for 0 or "", which is distinct from the natural behavior of the parameter.) RFC: https://wiki.php.net/rfc/deprecate_null_to_scalar_internal_arg Closes GH-6475.
* Added Inheritance Cache.Dmitry Stogov2021-02-091-0/+33
| | | | | | | | | | 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.
* Replace zend_bool uses with boolNikita Popov2021-01-151-26/+26
| | | | | | | 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.
* Remove Z_PARAM separate params where they don't make senseNikita Popov2021-01-141-72/+30
| | | | | | | | | Separation can only possibly make sense for array parameters (or something that can contain arrays, like zval parameters). It never makes sense to separate a bool. The deref parameters are also of dubious utility, but leaving them for now.
* Flesh out HashTable insertion APIsSara Golemon2020-12-011-0/+18
| | | | | | | | | | | | | | | | Fills out the array/object-property insert helpers for zend_array, zend_object, and zend_reference. This adds the following matrix of 18 APIs add_next_index_T() add_index_T() add_assoc_T() add_assoc_T_ex() add_property_T() add_property_T_ex() Where T in array, object, reference Converted internal callsites currently doing an explicit object wrap.

| | | | | | | | | | | | Export the zend_is_callable_impl() function as zend_is_callable_at_frame() for use by extension. As twose pointed out, an extension may want to retrieve fcc for a private method.

* Consolidate new union type ZPP macro namesMáté Kocsis2020-09-111-46/+46
| | | | | | | They will now follow the canonical order of types. Older macros are left intact due to maintaining BC. Closes GH-6112
* Make null byte error a ValueErrorNikita Popov2020-09-081-2/+2
| | | | | | | | | | | | | Currently we treat paths with null bytes as a TypeError, which is incorrect, and rather inconsistent, as we treat empty paths as ValueError. We do this because the error is generated by zpp and it's easier to always throw TypeError there. This changes the zpp implementation to throw a TypeError only if the type is actually wrong and throw ValueError for null bytes. The error message is also split accordingly, to be more precise. Closes GH-6094.

* Release call trampolines in zpp fccNikita Popov2020-09-041-0/+4
| | | | | | | | | | | | | | When using zpp 'f' or Z_PARAM_FUNC, if the fcc points to a call trampoline release it immediately and force zend_call_function to refetch it. This may require additional callability checks if __call is used, but avoids the need to carefully free fcc values in all internal functions -- in some cases this is not simple, as a type error might be triggered by a later argument in the same zpp call. This fixes oss-fuzz #25390. Closes GH-6073.

* Rehash function table after disabling functionsNikita Popov2020-08-281-1/+1
| | | | | | | | | | | | To perform fast shutdown without full table cleanup we need all internal functions to be in one continuous chunk. This was violated when functions were deleted via disable_functions. This drops the zend_disable_function() API in favor of zend_disable_functions(), which disables the given list of functions and performs the necessary rehash afterwards. Also drop PG(disabled_functions), which is no longer used.

* Implement named parametersNikita Popov2020-07-311-5/+35
| | | | | | | | | | | | | | | | | | From an engine perspective, named parameters mainly add three concepts: * The SEND_* opcodes now accept a CONST op2, which is the argument name. For now, it is looked up by linear scan and runtime cached. * This may leave UNDEF arguments on the stack. To avoid having to deal with them in other places, a CHECK_UNDEF_ARGS opcode is used to either replace them with defaults, or error. * For variadic functions, EX(extra_named_params) are collected and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS. RFC: https://wiki.php.net/rfc/named_params Closes GH-5357.

* Cache __unserialize() instead of unserialize()Nikita Popov2020-06-261-2/+2

* Add ZVAL_OBJ_COPY macroNikita Popov2020-06-171-0/+2

* Use unused attribute for _dummyNikita Popov2020-06-121-2/+1
| | | | | | | | | The (void)_dummy is apparently considered a read of an uninitialized variable. As it is a _Bool now, which has trap representations, this is no longer considered legal and results in somewhat odd ubsan warnings of the form: runtime error: load of value 0, which is not a valid value for type 'zend_bool' (aka 'bool')
* Add zend_call_known_function() API familyNikita Popov2020-06-091-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | This adds the following APIs: void zend_call_known_function( zend_function *fn, zend_object *object, zend_class_entry *called_scope, zval *retval_ptr, int param_count, zval *params); void zend_call_known_instance_method( zend_function *fn, zend_object *object, zval *retval_ptr, int param_count, zval *params); void zend_call_known_instance_method_with_0_params( zend_function *fn, zend_object *object, zval *retval_ptr); void zend_call_known_instance_method_with_1_params( zend_function *fn, zend_object *object, zval *retval_ptr, zval *param); void zend_call_known_instance_method_with_2_params( zend_function *fn, zend_object *object, zval *retval_ptr, zval *param1, zval *param2); These are used to perform a call if you already have the zend_function you want to call. zend_call_known_function() is the base API, the rest are just really thin wrappers around it for the common case of instance method calls. Closes GH-5692.
* Add helper APIs for maybe-interned string creationtwosee2020-06-081-24/+44
| | | | | | | | | | | | Add ZVAL_CHAR/RETVAL_CHAR/RETURN_CHAR as a shortcut for using ZVAL_INTERNED_STRING and ZSTR_CHAR. Add zend_string_init_fast() as a helper for the empty string / one char interned string / zend_string_init() pattern. Also add corresponding ZVAL_STRINGL_FAST etc macros. Closes GH-5684.
