It introduces a single function to check file paths passed to OpenSSL
functions. It expands the path, check null bytes and finally does
an open basedir check.
This does a compile time transformation of ``iterable`` into ``Traversable|array`` which simplifies some of the LSP variance handling.
The arginfo generation script from stubs is updated to produce a union type when it encounters the type ``iterable``
Extension functions which do not regenerate the arginfo, or write them manually are still supported by mimicking the compile time transformation while registering the function.
Type Reflection is preserved for single ``iterable`` (and ``?iterable``) to produce a ReflectionNamedType with name ``iterable``, however usage of ``iterable`` in union types will be converted to ``array|Traversable``
Newly added dl() tests trigger an assertion in ZEND_RC_DEBUG builds. This change
disables zend_rc_debug to allows these tests to pass until this issue is
resolved.
I did some historical digging and could not figure out why a copy is
made. Additionally, the copy was not using the `.size` member, so it
was probably wrong, but it's been that way for quite some time.
Class constants from parents should always be directly reused,
rather than re-evaluated as a separate copy. Previously this used
to happen automatically, as we'd just inherit the class constant
entry from the parent class. With mutable data there may now be
a separate copy of the constant, so we need to use that copy
when updating constants. Otherwise we may evaluate the same
constant multiple times.

Same as with userland classes, automatically add a string return
type to __toString() methods in internal classes, so the signature
is compatible with Stringable.
Requiring all internal classes (including those from 3rd-party
extensions) to implement Stringable if they provide __toString()
is too error prone. Case in point, our _ZendTestClass test class
was not doing so, resulting in preloading test failures after
recent changes.
Instead we automatically implement Stringable, the same as we do
for userland classes. We still allow explicit implementations,
but ignore them (normally they would result in an error due to
duplicate interface implementation). Finally, we need to be
careful about not trying to implement Stringable on Stringable
itself.
In some cases this changes the interface order, in particular the
automatic Stringable implementation will now come first.
Traits do not support interfaces, so we should not implement
Stringable on them.
Also check the __toString() return type in the same way other
magic methods do, otherwise we would now miss the check in the
trait case.
- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
This deprecates all callables that are accepted by
call_user_func($callable) but not by $callable(). In particular:
"self::method"
"parent::method"
"static::method"
["self", "method"]
["parent", "method"]
["static", "method"]
["Foo", "Bar::method"]
[new Foo, "Bar::method"]

Currently, CE_CACHE on strings is only used with opcache interned strings. This
patch extends usage to non-opcache interned strings as well. This means that
most type strings can now make use of CE_CACHE even if opcache is not loaded,
which allows us to remove TYPE_HAS_CE kind, and fix some discrepancies
depending on whether a type stores a resolved or non-resolved name.
There are two cases where CE_CACHE will not be used:
* When opcache is not used and a permanent interned string (that is not an
internal class name) is used as a type name during the request. In this case
we can't allocate a map_ptr index for the permanent string, as it would be
not be in the permanent map_ptr index space.
* When opcache is used but the script is not cached (e.g. eval'd code or
opcache full). If opcache is used, we can't allocate additional map_ptr
indexes at runtime, because they may conflict with indexes allocated by
opcache.
In these two cases we would end up not using CE caching for property types
(argument/return types still have the separate cache slot).
mutable_data may be used for IMMUTABLE classes, internal classes
and to-be-preloaded classes. Check whether the mutable_data
map_ptr is set rather than only the IMMUTABLE flag.
This adds support for internal enums with the same basic approach
as userland enums. Enum values are stored as CONSTANT_AST and
objects created during constant updating at runtime. This means
that we need to use mutable_data for internal enums.
This just adds basic support and APIs, it does not include the
stubs integration from #7212.
Closes GH-7302.
If fast_shutdown is used, then we don't need to destroy static
members at all. If fast_shutdown is not used, then we already
loop over classes to destroy static members and static variables
in methods.
While parent:: should inherit the called scope, it should only do
so if it is compatible. If there is no called scope, or it is not
a subtype of the scope, we should fall back to the scope.
When running without opcache, static_members_table is shared with
default_static_members_table. This is visible in reflection output,
because ReflectionProperty::getDefaultValue() will return the
current value, rather than the default value.
Address this by never sharing the table, which matches the behavior
we already see under opcache.
Fixes bug #80821.
Closes GH-7299.
Add support for new expressions inside parameter default values,
static variable initializers, global constant initializers and
attribute arguments.

Closes GH-7153.
Updating based on the properties info HT will miss private parent
properties that have been shadowed in the child class. Instead,
perform updating directly on the default properties table.
We can't do the same for static properties, because those don't
have a convenient way to look up the property type from the
property offset. However, I don't believe the problem exists for
static properties, because we're always going to be using the
property on the class it was declared on, while children only hold
INDIRECT references. As such, this should be covered by parent
class const updating.
Fixes oss-fuzz #35906.
