Remove the `swf_version` parameter from `Activation` constructors,
because this was incorrectly using the global or root SWF version
most times.
Instead, grab the SWF version for the activation directly from the
base clip.
Remove the preload step that would pre-create the shapes for each
morph shape ratio on SWF load. Instead, lazily crate the shapes
when they are needed.
`core` already depends on the `instant` crate which abstracts
`std::instant::Instant` and polyfills it on Web. Use it to replace
`NavigatorBackend::time_since_launch` in order to make `NavigatorBackend`
a little smaller and more simple.
Previously there were 3 implementations of `LocaleBackend`:
`DesktopLocaleBackend`, `WebLocaleBackend` and `NullLocaleBackend`.
While `DesktopLocaleBackend`, `WebLocaleBackend` were identical,
`NullLocaleBackend` always returned a fixed date/time for tests
determinism.
Unify them in a single file, and use `cfg!(test)` and a new dedicated
`deterministic` feature to decide whether to mock date/time or not.
This should not cause any behavioral changes.
Instead of storing shared pointers to `Avm1ConstructorRegistry` in
`MovieLibrary`, access the `PropertyMap` directly, without an extra
abstraction.
Also, move the constructor registries to `Avm1`, for better
encapsulation.
This requires adding another notion of mouse-release events to `ClipEvent`. We now have four:
* `MouseUp` - the mouse was released, any object on the render list can handle this event ("anycast" event)
* `MouseUpInside` - the mouse was released inside this display object, only the mouse-picked target of the event can handle it
* `Release` - the mouse was released inside the last clicked display object
* `ReleaseOutside` - the mouse was released outside the last clicked display object
For those keeping score at home, in AVM2, the valid progression of events is either...
* On the same object, `mouseDown`, `mouseUp`, and `click`
* On one object, `mouseDown`, then some mouse movement that takes the cursor out of the first object, then on another object `mouseUp`, and then finally the first object gets `releaseOutside`.
`onLoadInit` is queued after all `DoAction`s of the loaded clips.
That is, if clip1, clip2, clip3 are loaded in the same frame
(in this order), then actions will be executed as follows:
* `DoAction` of clip3
* `DoAction` of clip2
* `DoAction` of clip1
* `onLoadInit` of clip3
* `onLoadInit` of clip2
* `onLoadInit` of clip1
Previously, those were incorrectly executed as follows:
* `DoAction` of clip3
* `onLoadInit` of clip3
* `DoAction` of clip2
* `onLoadInit` of clip2
* `DoAction` of clip1
* `onLoadInit` of clip1
`handle_clip_event` is now a default trait method that calls three methods in order:
* `filter_clip_event`, to determine which events that either this object or it's children may handle
* `propagate_to_children`, to check if any children of this object want to handle an event. (This also includes AVM2 button states, which are not technically "children" in the usual sense...)
* `event_dispatch`, which does the actual "object reacts to an event" bit if no child handles the object.
These roughly correspond to phases of existing event-handling objects pre-`InteractiveObject`.
Use prototype depths instead. Most calls passed `base_proto = None`,
which is equivalent to `depth = 0`, and is now the default.
The few other cases were adapted to use `Executable::exec` directly,
where `depth` can be specified manually.
The last usage of it was in `Player`, which anyway should operate
only on newly created objects that don't have any virtual properties
nor watchers. So it is safe to replace with `define_value`, that
also cannot fail.
`__proto__` seems to behave much like a regular data property. So
simply remove the `prototype` field of `ScriptObject` in favor of
storing the prototype in the general properties hash map.
This also incurred a large number of ancillary changes, as it turns out nearly every native object is currently pulling a prototype and sticking it into an object. Right now, I have it instead pulling the constructor out of the prototype, but a future PR will also remove `system_prototypes` as well.
Other ancillary changes include:
* `Domain` now supports partial initialization to avoid an order-of-events issue. Accessing domain memory on a partially-initialized `Domain` will panic.
* `Domain` construction requires a full `activation` now, except for `global_scope` which needs to be initialized later with valid domain memory before user code runs.
* Pretty much every native object constructor now takes a proto/constr pair
* Trait lookup was rewritten to handle this. It's still buggy - seven tests don't work
* `TObject.construct` now actually does the full object construction dance. This allows `ClassObject` to implement the ES4 object construction pathway directly while `FunctionObject` maintains ES3 compatibility.
This is a tentative commit; there are still seven failing tests that I need to fix.
When reading an SWF, search for FileAttributes and
SetBackgroundColor and return this along with the header data
because it's useful (in particular, the AS3 flag).
Move `MovieClip::is_swf` flag to `DisplayObject::is_root`, and use
this flag to handle the behavior of `DisplayObject.root` crawling
upwards until it hits a top-most loaded SWF/Bitmap.
Simplify `root` and `stage` so that they don't have to consider
buttons. Instead, do some trickery to ensure the button's states
see the proper values of `parent`, `root`, and `stage` during
construction.
Add `RufflePlayer.metadata` that exposes the SWF header fields to
JavaScript.
Add `RufflePlayer.readyState` and fire a `loadedmetadata` event
once the metadata is available, mimicking the HTML5 media APIs.
This appears to only be in use for AVM2. Objects placed on a given frame are constructed before anything else happens with it's parent - even it's constructor being called. This involves splitting AVM2 up into a bunch of steps that really don't make sense for AVM1 content. Hence, `construct_frame` is a no-op for AVM1 and pre-running the first frame when instantiated is AVM1 exclusive now.
