Currently, trait methods are aliased will continue to use the
original function name. In a few places in the codebase, we will
try to look up the actual method name instead. However, this does
not work if an aliased method is used indirectly
(https://bugs.php.net/bug.php?id=69180).
I think it would be better to instead actually change the method
name to the alias. This is in principle easy: We have to allow
function_name to be changed even if op array is otherwise shared
(similar to static_variables). This means we need to addref/release
the function_name separately, but I don't think there is a
performance concern here (especially as everything is usually
interned).
There is a bit of complication in opcache, where we need to make
sure that the function name is released the correct number of times
(interning may overwrite the name in the original op_array, but we
need to release it as many times as the op_array is shared).
Fixes bug #69180.
Fixes bug #74939.
Closes GH-5226.
In order of preference, the generated name will be:
new class extends ParentClass {};
// -> ParentClass@anonymous
new class implements FirstInterface, SecondInterface {};
// -> FirstInterface@anonymous
new class {};
// -> class@anonymous
This is intended to display a more useful class name in error messages
and stack traces, and thus make debugging easier.
Closes GH-5153.
RFC: https://wiki.php.net/rfc/static_return_type
The "static" type is represented as MAY_BE_STATIC, rather than
a class type like "self" and "parent", as it has special
resolution semantics, and cannot be cached in the runtime cache.
Closes GH-5062.
This helps to avoid unnecessary IS_REFERENCE checks.
This changes some notices "Only variables should be passed by reference" to exception "Cannot pass parameter %d by reference".
Also, for consistency, compile-time fatal error "Only variables can be passed by reference" was converted to exception "Cannot pass parameter %d by reference"
We need to extend the hash table before performing raw append
operations.
This doesn't matter if preloading happens in the same process,
as the tables will be large enough to hold all entries as a
side-effect of the preloading process. However, if preloading
happens in a different process, we need to reserve space here.
