Newer versions of PHP in 5.4 and 5.5 line add micro seconds
precision to datetime representations.
This adds a regular expression to ignore the .000000 suffix.
Use v8::Persistent handle to keep module instances around.
Objects cannot be shared between isolates anyhow, hence moved
modules_loaded map from global V8JSG structure to php_v8js_ctx.
Besides fixes a use-after-free on normalised_module_id.
Before the idle notifications to V8 were sent without a special
Isolate entered, which results in V8 using it's default isolate
(which we don't use at all). Hence those were pretty useless
anyways (if they were called, which was unlikely).
Besides V8 seems to not trigger the weak object callbacks if
the isolate is destroyed, hence the PHP objects we add-ref'ed
before will leak.
Therefore this removes the previous idle notification logic
and forces garbage collection from the V8Js object destructor.
Use the NamedPropertyHandler feature of v8 to wrap accesses to PHP properties
and methods from JavaScript. This enables us to support property
set/delete/query.
The `in` and `delete` operators in JavaScript work like the `isset()` and
`unset()` functions in PHP. In particular, a PHP property with a null
value will not be `in` the JavaScript object. (This holds when enumerating
all properties of an object as well.)
Because JavaScript has a single namespace for both properties and methods,
we allow the use of the `__call` method on a PHP object (even if the
PHP class does not natively define the `__call` magic function) in order
to unambiguously invoke a method. Similarly, you can prefix a property
name with `$` to unambiguously access the property. (When enumerating all
properties, properties are `$`-prefixed in order to ensure they are not
conflated with method names.)
Use the v8::Signature parameter to FunctionTemplate::New to guarantee that
the info->Holder() is of the proper type when `php_v8js_php_callback` is
invoked.
Add test case demonstrating the segfault (which is now prevented).
