`new Reflectionproperty($scope, $propName)` keeps a reference to the
zend_property_info of $propName declared in $scope. In getRawValue() and
related methods, we use this reference to check whether the property is hooked.
Calling `new ReflectionProperty($scope, $propName)->getRawValue($object)` is
equivalent to the expression $object->$propName from scope $scope (except that
it bypasses hooks), and thus may access an overridden property (unless the
original is private). This property may have hooks and different flags.
Here I fetch the effective property info before checking for hooks and
property flags.

Closes GH-17714
Normally, accesses to properties marked as lazy trigger the object's
initialization, or forward to a real instance if the object is an initialized
proxy.
The purpose of ReflectionProperty::setRawValueWithoutLazyInitialization() and
ReflectionProperty::skipLazyInitialization() is to bypass auto-initialization,
so that some properties can be initialized without triggering initialization.
However, when the object is an initialized proxy, these methods would
unexpectedly update the proxy.
Here I make sure that these methods have an effect on the real instance, when
the object is an initialized proxy.
Fixes GH-16344
Additionally fixes wrong behaviour in ReflectionParameter when you first
have a construction that uses an object and the subsequent doesn't.

* reflection: Fix the return value of ReflectionFunction::{getNamespaceName,inNamespace}() for closures
Fixes GH-16122
* reflection: Clean up implementation of `ReflectionFunctionAbstract::inNamespace()`
* reflection: Clean up implementation of `ReflectionFunctionAbstract::getNamespaceName()`
For the `Exception`, `ReflectionClass`, and `ReflectionAttribute` classes, the
`__clone()` method is declared to be private, and the implementation has a
comment that it should never be executed. However, the implementation can be
executed by using a `ReflectionMethod`. Fix the comments to instead explain why
the implementation is needed.

Dynamic properties are generally referred to as "dynamic" properties, while
non-dynamic properties are not commonly referred to as "default" properties.
Thus, the existing method `ReflectionProperty::isDefault()` has a non obvious
name; while an alias could be added for `isNotDynamic()`, a new `isDynamic()`
method seems cleaner. The new method returns the opposite of `isDefault()`;
dynamic properties are not present on the class by default, and properties
present by default are not added dynamically.
Closes GH-15754
For dynamic properties, instead of crashing with a segmentation fault, just say
that there are no hooks. Also includes a test to prevent regression.
Fixes GH-15718

This is useful to reduce the memory usage of objects that don't actually
use the backing storage. Examples are XMLReader and DOM. When the
properties were added to the stubs, these objects became much much
bigger, which is a waste of memory.

* Include from build dir first
This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.
Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :
-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/
As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.
After this change, the include path is defined as follows:
-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
* Fix extension include path for out of tree builds
* Include config.h with the brackets form
`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.
Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.
* Make `ReflectionGenerator::getFunction()` legal after generator termination
* Expose the generator function name via `Generator::__debugInfo()`
* Allow creating `ReflectionGenerator` after termination
* Reorder `struct _zend_generator` to avoid a hole
* Adjust `ext/reflection/tests/028.phpt`
This is legal now.
* Fix Generator Closure collection
* Add test to verify the Closure dies with the generator
* NEWS / UPGRADING
* Add `zend_get_attribute_object()`
This makes the implementation for `ReflectionAttribute::newInstance()`
reusable.
* Add test for the stack trace behavior of ReflectionAttribute::newInstance()
This test ensures that the `filename` parameter for the fake stack frame is
functional. Without it, the stack trace would show `[internal function]` for
frame `#0`.
* Fix return type of `call_attribute_constructor`
Fixes GH-13970
Closes GH-14105
We cannot validate at compile-time for multiple reasons:
* Evaluating the argument naively with zend_get_attribute_value can lead to code
execution at compile time through the new expression, leading to possible
reentrance of the compiler.
* Even if the evaluation was possible, it would need to be restricted to the
current file, because constant values coming from other files can change
without affecting the current compilation unit. For this reason, validation
would need to be repeated at runtime anyway.
* Enums cannot be instantiated at compile-time (the actual bug report). This
could be allowed here, because the value is immediately destroyed. But given
the other issues, this won't be needed.
Instead, we just move it to runtime entirely. It's only needed for
ReflectionAttribute::newInstance(), which is not particularly a hot path. The
checks are also simple.
This allows consumers of just the CSPRNG to include a much smaller header. It
also allows to verify at a glance whether a source file might use non-secure
randomness.
This commit includes the new header wherever the CSPRNG is used, possibly
replacing the inclusion of php_random.h if nothing else is used, but also
includes it in the main php_random.h header for compatibility.
Somewhat related to 45f8cfaf10,
2b30f18708, and
b14dd85dca.
There were 4 different reports of this breaking behavior. This is higher than I
expected. This bug fix may still be desirable, but should be discussed on the
list beforehand.
Closes GH-12127
Evaluating constants at comptime can result in arrays that contain objects. This
is problematic for printing the default value of constant ASTs containing
objects, because we don't actually know what the constructor arguments were.
Avoid this by not propagating array constants.
