Mike Welsh d7740bc3ad core: Don't touch UpdateContext::active_clip in DisplayObjects
DisplayObject code no longer has to manage
UpdateContext::active_clip before calling out to children, because
each child still has access to its Gc pointer.

David Wendt 16259ad74a Calling uncallable values does not actually cause a runtime error in Flash; it just returns null.
This was discovered almost by accident: @Dinnerbone noticed that `_global == null`, and surmised that `valueOf` was the culprit. However, this doesn't really make sense: `_global` is a bare object, so it shouldn't have a `valueOf` (and in practice, it doesn't).

The ultimate cause of such an odd comparison is as such:

1. Flash coerces the `_global` object to a numerical primitive by calling `valueOf`.
2. `_global.valueOf` is undefined. Flash handles calls to any uncallable value by literally just having it return `undefined`. In other words, all values are implicitly callable as empty functions.
3. `undefined` is then compared to `null`. These two values *are* equal under abstract equality (`==`). Hence, `_global == null`.

For comparison, modern ECMAScript engines throw errors on calls to uncallable values; and won't attempt to use an invalid `valueOf` to coerce objects. So none of this applies to, say, standard JavaScript in your browser.

David Wendt 129d50bfa6 Implement ECMAScript compliant type coercions.
This includes ECMA-262 2ed `ToNumber`, `ToPrimitive` (Number), `ToString`, and abstract equality and less-than implementations. Note that `ToPrimitive` is only the "number hint" variant, and Flash specifically *never* calls `toString` like how ECMA-262 specifies.

Several builtins inherit numerical coercion - I'm not 100% sure if that's correct.

The following ActionScript opcodes now perform ECMA-262 style coercions:

`ActionAdd2` (uses `valueOf` / "ToPrimitive hint Number")
`ActionDecrement` (uses `valueOf`)
`ActionEquals2` (uses `valueOf`)
`ActionGetMember` (member names, uses `toString`)
`ActionIncrement` (uses `valueOf`)
`ActionLess2` (uses `valueOf`)
`ActionGreater` (uses `valueOf`)
`ActionSetMember` (member names, uses `toString`)
`ActionStringEquals` (uses `toString`)
`ActionStringGreater` (uses `toString`)
`ActionStringLess` (uses `toString`)
`ActionToNumber` (uses `valueOf`)
`ActionToString` (uses `toString`)
`ActionTrace` (uses `toString`)

The following functions now gained user-specified coercions via `toString`:
`_global.number` (uses `valueOf`)
`_global.is_nan` (uses `valueOf`)
Every function in `Math` (uses `valueOf`)

David Wendt 3c8d9b9c1c `new` should be called on the prototype - not the constructor function. This will allow different host object impls to subclass correctly. 2019-11-26 14:51:06 -05:00
David Wendt 0e59e1c961 Allow host-provided constructors to override `new` and provide host objects to the AVM when a particular constructor is called. 2019-11-26 14:51:06 -05:00
David Wendt d25bdbacf8 Separate `Object` into an interface trait and a standard implementation. Host object implementations may bypass `ScriptObject` and directly interface with the AVM using this trait.
Note that host objects that do so will *not* have access to their standard representation from within member functions - you will need to extend the interface to accomodate for them. This is due to long-standing limitations with type IDs and downcasting with types that bear lifetimes - it's entirely an unsafe operation and exposing such a facility to safe Rust is unsound. However, this will at least let us separate out several things from ScriptObject that don't need to be there for the time being.

David Wendt 813783881b Implement explicit prototypes on user-generated functions.
`Object::function` now returns a pre-allocated function object. You may supply it an explicit prototype to have it linked into the function object (which is why we have to return a cell).

David Wendt bc74b2fc4a Track the no-double-reader flag on a per-frame basis, and add a "run until current frame exits" routine. 2019-11-20 14:30:31 -05:00
David Wendt a2ee7f9e3a Replace `Option<Value<'gc>>` with a dedicated `ReturnValue<'gc>` type with associated methods.
This type explicitly signals if an immediate value is to be returned, if a value is to be returned on the stack, or if no return value is to be generated. Holders of a `ReturnValue` can also use `and_then` to schedule a `StackContinuation` to be executed when and if that value is ready.

`StackContinuations` now yield `ReturnValues` as well, so they have a moderate level of composability. For example, if you need to get a property from an object and push it on the stack, you can return the result of calling `get` directly and the machinery ensures it eventually gets there.

David Wendt 9d422dc269 Allow getters to resolve on the AVM1 stack.
This involved yet another macro, `and_then!`, to avoid a ridiculous amount of duplicate code. It calls a continuation whenever it's value is ready, even if the value resolved on the Rust stack.

`locals_into_form_values` does not currently support this. It skips any property that does not resolve on the Rust stack. Future work is required to resolve this.
2019-11-20 14:30:30 -05:00
David Wendt a59fffbc4e Ensure that the value of the newly constructed `this` is returned in all cases.
This involves the use of a "stack continuation" system. Due to previous lifetime issues with using closures directly (see `8ea6c6234dba925ec5fbc61502627fb62b05916c`), we instead use a macro that constructs a `Collect`able type holding the things the continuation needs to continue working with. The syntax is largely similar to Rust closures but with the addition of an explicit list of bound variables, all of which must be `Collect`.

David Wendt a95861d596 Stack continuations can now directly manipulate the return value of an ActionScript function. 2019-11-20 14:30:29 -05:00
David Wendt 8485e919db Add a notion of "and_then" to activation objects.
This effectively constitutes the ability to assign arbitrary native contiuations to the AVM stack.

This pushes an extra `undefined` onto the stack to fix underflow in AS2 interface declarations.

It is currently unknown if this is a miscompilation or if some other value is supposed to be there.

David Wendt 7e2cf03789 Implement register underflow behavior.
This has the side effect of letting us remove the `Option` on register_count since setting this to `0` is equivalent now. Furthermore, we can skip an allocation if a function requests no registers.

Mike Welsh c8cec3132f avm1: Fix GotoFrame2 one-frame-off error
Frame numbers pushed/popped from the stack for GotoFrame2 are
1-based. This differs for GotoFrame which is 0-based and encodes
the frame alongside the instruction.

Mike Welsh 7b63dc05c4 core: Initial implementation of SetTarget2
Implement the SetTarget2 action, which pops the target off of the
stack, and GetProperty 11, which pushes _target.

However, our implementation of _target is not accurate yet,
because it requires dynamically building the target path. Currently
we fake it by caching the last path to tellTarget.

Mike Welsh 856a4c6130 core: Improve TellTarget support
The AVM1 contains an explicit "target clip" that is used for older
Flash 4-era actions. This target clip can be set to an invalid
value, at which point Play, Stop, etc. will fail silently.

For GetVariable and SetVariable, if the target is invalid,
the variables will be modified on root ("/").
