This is a private property, so we are allowed to add a type.
The new declaration of the property is:
private array $trace = [];
This ensures that Exception::getTrace() does indeed return an array.
Userland code that was modifying the property through refleciton
may have to be adjusted to assign an array (instead of null,
for example).
Closes GH-5636.
From now on, we always display the given object's type instead of just reporting "object".
Additionally, make the format of return type errors match the format of argument errors.
Closes GH-5625
We have a bunch of APIs for getting type names and it's sometimes
hard to keep them apart ... make it clear that this is the one
you definitely do not want to use.
Currently, disabling a function only replaces the internal
function handler with one that throws a warning, and a few
places in the engine special-case such functions, such as
function_exists. This leaves us with a Schrödinger's function,
which both does not exist (function_exists returns false) and
does exist (you cannot define a function with the same name).
In particular, this prevents the implementation of robust
polyfills, as reported in https://bugs.php.net/bug.php?id=79382:
if (!function_exists('getallheaders')) {
function getallheaders(...) { ... }
}
If getallheaders() is a disabled function, this code will break.
This patch changes disable_functions to remove the functions from
the function table completely. For all intents and purposes, it
will look like the function does not exist.
This also renders two bits of PHP functionality obsolete and thus
deprecated:
* ReflectionFunction::isDisabled(), as it will no longer be
possible to construct the ReflectionFunction of a disabled
function in the first place.
* get_defined_functions() with $exclude_disabled=false, as
get_defined_functions() now never returns disabled functions.
Fixed bug #79382.
Closes GH-5473.
This is only used in reflection, where doing a simple string check
is acceptable.
I'm also dropping the "dtor" printing in the reflection dump.
Dtors are just one of many magic methods, I don't think there's
a point in explicitly highlighting them, when the name is already
unambiguous.
The callable name is provided also if it's not callable, in which
case it's basically "what it would be if it were callable", which
is ClassName::__invoke. The current behavior of casting the object
to string makes very little sense as this will just throw an
exception for most objects.
Avoid subtle differences in behavior depending on whether the
handler is absent or returns FAILURE.
If you previously set cast_object to NULL, create a handler that
always returns FAILURE instead.
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.

This is inline with similar changes to the math functions. Especially,
array to number conversion makes no sense here, and is likely to hide
a programming error.
To make that feasible, we introduce the `n` specifier for classic ZPP
so we can stick with `zend_parse_method_parameters()`.
We also remove a test case, which has been degenerated to a ZPP test.
