* PHP-8.3:
Fix GH-18309: ipv6 filter integer overflow
Fix GH-18304: Changing the properties of a DateInterval through dynamic properties triggers a SegFault
For dynamic fetches the cache_slot will be NULL, so we have to check for
that when resetting the cache. For zip and xmlreader this couldn't
easily be tested because of a lack of writable properties.
Closes GH-18307.
$start and $end use the H:i:s from the current time. If $end happens on
a second boundary, $start + 4 days will include $end, thus performing an
extra iteration. Fix this by setting H:i:s to 00:00:00.
The cache slot for FETCH_OBJ_W in function `test` is primed with the
class for C. The next call uses a simplexml instance and reuses the same
cache slot. simplexml's get_property_ptr handler does not use the cache
slot, so the old values remain in the cache slot. When
`zend_handle_fetch_obj_flags` is called this is not guarded by a check
for the class entry. So we end up using the prop_info from the property
C::$a instead of the simplexml property.
This patch adds a reset to the cache slots in the property address fetch
code and also in the extensions with a non-standard reference handler.
This keeps the run time cache consistent and avoids the issue without
complicating the fast paths.
Closes GH-17739.
`timelib_astro_rise_set_altitude()` is not prepared to deal with non-
finite values (`nan`, `inf` and `-inf`) for `lon` and `lat`; instead
these trigger undefined behavior. Thus we catch non-finite values
before even calling that timelib function; for `date_sun_info()` we
trigger `ValueError`s; for `date_sunrise()` and `date_sunset()` we
silently return `false`, since these functions will be sunsetted
anyway.
Closes GH-16497.
After normalization, `N` is supposed to be in range [0, 24], but for
very large and very small `$utcOffset` this is not necessarily the
case, since the normalization might yied `-inf` or `inf`. If that
happens, we let the function fail silently, since it is highly unlikely
that such `$utcOffset`s are passed in practice.
Closes GH-16483.
To match other capitalized strings like `ZEND_STR_UNKNOWN_CAPITALIZED` and
`ZEND_STR_ARRAY_CAPITALIZED`. Since this known string was only added in PHP
8.4, no backwards compatibility alias is needed.
When a class (or enum) has no methods, rather than using an array that only
contains `ZEND_FE_END`, use `NULL` for the functions. The implementation of
class registration for internal classes, `do_register_internal_class()` in
zend_API.c, already skips classes where the functions are `NULL`. By removing
these unneeded arrays, we can reduce the size of the header files, while also
removing an unneeded call to zend_register_functions() for each internal class
with no extra methods.
Currently, internal classes are registered with the following code:
INIT_CLASS_ENTRY(ce, "InternalClass", class_InternalClass_methods);
class_entry = zend_register_internal_class_ex(&ce, NULL);
class_entry->ce_flags |= ...;
This has worked well so far, except if InternalClass is readonly. It is because some inheritance checks are run by zend_register_internal_class_ex before ZEND_ACC_READONLY_CLASS is added to ce_flags.
The issue is fixed by adding a zend_register_internal_class_with_flags() zend API function that stubs can use from now on. This function makes sure to add the flags before running any checks. Since the new API is not available in lower PHP versions, gen_stub.php has to keep support for the existing API for PHP 8.3 and below.
