Instead mark name/value as readonly and the class as
NO_DYNAMIC_PROPERTIES. This gives us the desired limitations
using native features.
In fact, this also fixes a bug where opcache cache slot merging
might result in a write to the name/value properties being
allowed. The readonly implementation handles this case correctly.
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).
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 readonly properties, for which only a single
initializing assignment from the declaring scope is allowed.

Closes GH-7089.
Add support for new expressions inside parameter default values,
static variable initializers, global constant initializers and
attribute arguments.

With this patch, it is no longer required to call
`ReflectionProperty#setAccessible()` or
`ReflectionMethod#setAccessible()` with `true`.
If a userland consumer already got to the point of accessing
object/class information via reflection, it makes little sense
for `ext/reflection` to disallow accessing `private`/`protected`
symbols by default.
After this patch, calling `ReflectionProperty#setAccessible(true)`
or `ReflectionMethod#setAccessible(true)` on newly instantiated
`ReflectionProperty` or `ReflectionMethod` respectively will have
no effect.

Closes GH-5412.
Implement printing for ReflectionAttribute. Attributes aren't
printed as part of reflection output for other structures (classes
etc) yet.
Closes GH-6117.
There was a loophole here when it came to usage with named arguments,
which was not intended. Close the loophole thoroughly by actually
dropping the default value from the signature entirely. The default
is still used to make the type nullable, but not for anything else.
Because php supports doc comments on class constants, I believe it would also
make sense to support them on enum cases.
I don't have strong opinions about whether attributes should be moved to be the
last element or whether the doc comment should go after the attribute,
but the ast will likely change again before php 8.1 is stable.
So far, all attributes are the last ast child node.
I didn't notice that doc comments weren't implemented due to
https://github.com/php/php-src/pull/6489 being a large change.
https://wiki.php.net/rfc/enumerations
did not mention whether or not doc comments were meant to be supported
Now similar "fake" frames now materialized when fetching debug
backtraces. The patch also fixes few incorrect backtraces for generators
in *.phpt tests.
This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)
