`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.
Resolving `_levelN` had some inconsistencies with Flash:
1. `_flash` can be a prefix too.
2. The level ID parsing cannot fail; non-digit characters are ignored,
the value wraps around at `i32::MAX`, and negative values are valid.
This logic is relevant also for the `GetUrl` and `GetUrl2` opcodes.
For now only add TODOs for this.
This PR adds the following class stubs:
* 'flash.display.Loader'
* 'flash.net.URLRequest'
* 'flash.ui.Keyboard'
* 'flash.utils.Timer'
These are needed for 'This is the Only Level TOO' (though we'll need
actual implementations to get this game past the loading screen).
Previously, `isFinite()` with no arguments on SWF<7 incorrectly
returned `true`, as `undefined` coerced to `f64` is `0.0`, which
is finite. Fix this by not defaulting to `undefined`, similarly to
the `isNaN()` implementation.
Instead of returning a `Result` which is anyway always handled with
a `log::warn!()`, simply `log::warn!()` in place of errors. This
removes the last 3 remaining `Error` enum members besides `InvalidXml`.
The 2 existing usages of `remove_node` always operated on a child and
its parent: One iterates over all of its children and removes each one,
and the other explicitly grabs the parent of a given node.
As a simplification, `remove_node` operates only on a child node,
without the need for the parent node in addition; it grabs the parent
from the child by itself. As such, it's non-failable.
Text nodes are guaranteed to not be parents, as `adopt_child`
refuses to adopt children into them. So instead of returning an
`Err(Error::TextNodeCantHaveChildren)` in case of a text node parent,
mark those code paths as `unreachable!()`. This makes `orphan_child`
non-failable.
The `json` crate seems unmaintained, and recently also causes compile
errors with stable Rust 1.59.0. On the other hand, `serde_json` is
very maintained and more popular.
However, from some reason a cyclic package dependency has introduced
by this change. For now use a workaround from: https://github.com/tkaitchuck/aHash/issues/95#issuecomment-903560879
This is basically a revert of 61298b2be3.
`SharedObject`s used to be saved as JSON in Ruffle, but since #4238
they're saved in AMF to match Flash's behavior. The legacy JSON
deserialization remained for backwards-compatibility, but from what it
seems, it has never worked; cd1cde1708
changed `LocalStorageBackend` to store base64-encoded strings instead
of plain ones. Therefore, Ruffle attempts to base64-decode old JSON
data, and unsurprisingly fails.
In addition, this removes 1 out of 2 usages of the unmaintained `json`
crate, which recently also causes compile errors with stable Rust 1.59.0.
The only use of `last_parse_error` was in the `XML.prototype.status`
property, where it was converted into a number. Avoid storing it by
storing just the number.
Revert some of e50aea864b for an even
better approach - Remove `XmlNodeObject::empty_node` entirely by
making `XmlNodeObject::from_xml_node` a suitable alternative. That is,
being able to accept a custom `proto` like before.
Also, make it return an `XmlNodeObject` instead of an `Object`, and
add a few `.into()` where needed.
* Don't use `quick_xml::Writer` for formatting the XML, being much
more simple.
* Return `WString` instead of `String`, reducing `to_utf8_lossy()`
calls except when the string needs to be escaped (attribute values
and text contents).
