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.

Mike Welsh 23ca66a7e3 avm1: Use enum_trait_object for avm1::Object 2019-12-10 01:36:01 -08:00
Mike Welsh b27bc578e0 core: Add enum_trait_object proc macro 
The enum_trait_object attribute macro can be used to define an enum where
each variant holds an implementor of a trait. It implements all
methods to forward to the underlying object, as well as `From` impls.

This an aliternative to using trait objects that gets along nicer
with `gc-arena`.

Mike Welsh 29754eace8 web: Avoid `copyToChannel` on Safari 
`AudioBuffer.copyToChannel` does not work on Safari, so switch to
using `getChannelData` to fill the audio buffers.

Limitations in wasm-bindgen prevent us from actually modifying the
data returned by `getChannelData` on the Rust side, so import a JS
function to fill the audio buffer (js-src/ruffle-imports.js).

David Wendt 89e060be4e Add a regression test for `_global` being a bare object 2019-11-28 20:53:31 -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 504f962256 Add a test for every string coercion I could find. 2019-11-28 20:28:46 -05:00
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`)
