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.
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::$a instead of the simplexml property.
This patch adds a reset to the cache slots in the property address fetch
code and also in the extensions with a non-standard reference handler.
This keeps the run time cache consistent and avoids the issue without
complicating the fast paths.
Closes GH-17739.
The only difference between `DateTime::__wakeup()` and
`DateTimeImmutable::__wakeup()` is which class name is included in the error
message if the initialization from the data fails. Factor out a helper method
that is given the class name, and use it for both methods.
`timelib_astro_rise_set_altitude()` is not prepared to deal with non-
finite values (`nan`, `inf` and `-inf`) for `lon` and `lat`; instead
these trigger undefined behavior. Thus we catch non-finite values
before even calling that timelib function; for `date_sun_info()` we
trigger `ValueError`s; for `date_sunrise()` and `date_sunset()` we
silently return `false`, since these functions will be sunsetted
anyway.
Closes GH-16497.
After normalization, `N` is supposed to be in range [0, 24], but for
very large and very small `$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.
