Mike Welsh bf0b777246 avm1: Use ECMA-262 ToInt32 modulo behavior
Everything is a double in ES land, so when converting a number to
int, the double is modulo'd to allow for wrapping 32-bit int
semantics.

See ToInt32 and ToUInt32 in the specs:

David Wendt 854526923e Calls to `super` inherently bind to itself.
This requires some subclassing nonsense to be able to smuggle a self-reference into `SuperObject`s. When successfully smuggled, all calls to `call` will be invoked with the `super` object as `this`. This allows constructor chaining to work.

Note that not all `Object` trait methods are implemented on `SuperObject`, so things like `delete this.x` in super constructors will randomly fail. This should be fixed.

David Wendt eb06501492 Since `get_local` doesn't scale the prototype chain anymore, we don't need to change the prototype chain traversal anymore. 2019-12-15 13:32:04 -08:00
David Wendt 5c1ac19c1b Implement `super`, mostly.
We implement `super` by way of a new `Object` impl which wraps arbitrary objects with a modified prototype chain. Specifically, the lowest layer of the prototype chain is omitted. This new `SuperObject` script is composable: a chain of two `SuperObject`s will go two levels of inheritance upwards while still maintaining non-prototype property access.

David Wendt f856243247 Primitive coercions should not yield an object just because valueOf is undefined. 2019-11-28 20:53:32 -05:00
David Wendt ec3ac4e5d6 `undefined` coerces to `0.0` on SWF6 2019-11-28 20:53:32 -05:00
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 2c87888e28 Implement prototype chain recursion limit of 255 prototypes.
In Flash, this also at least claims to halt ActionScript execution on the movie. No such implementation of AVM poisoning currently exists in Ruffle, primarily because it's unclear what gets poisoned and implementing some of these options isn't yet possible:

1. AVM (e.g. all movies) - we would need to make the AVM fail silently in this case. This is the most straightforward way to poison the movie, but I'm not sure if this is how Flash actually does it, or if it poisons...
2. Movie - the current structure of movies is incompatible with adding arbitrary data to them. We need to merge `moviefetch` in before we can attach data to loaded movies.
3. MovieClip - this would also be implementable but has problems. How do child MovieClips know that their parent has been poisoned, or vice versa? What if a movie clip is loaded from one movie and moved into another?

As a result, I have decided to hold off on implementing recursion poisoning until I know where it's supposed to go and how to implement that.

David Wendt 73c3b42cd4 Move `force_set` and `force_set_virtual` into the `Object` trait. They are now called `define_value` and `add_property`, respectively.
While I don't expect every host object to implement it correctly, this also gets rid of a lot of unnecessary `unwrap` calls that would allow a poorly-written Flash file to kill the interpreter.

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 b8c24890fc Allow overwriting read-only virtual properties in scope chains.
The previous behavior had an oversight: if you tried to set a variable with the same name as an in-scope property, it would always try to overwrite that property. This can fail silently and doesn't match with Flash Player behavior. Now, an attempt to overwrite a read-only property is instead correctly rejected so that it can be defined in local scope.

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 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.

David Wendt 269775c0e1 Implement the SWF5 version negotiation algorithm.
On SWF5, the SWF version of the callee depends on it's this parameter. Calling it as a function rather than a method downgrades the callee. SWF6+ use the callee's inherent SWF version and do not allow changing the SWF version like this.

2. With scopes are now always inserted behind the current set of locals rather than overriding them
3. `ActionSubtract` now subtracts (instead of adds)

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 ("/").
