Previously, the MovieClip error state contained one TODO in order to be
completely implemented: The HeaderExt variable uncompressed_len needs to
be -1 in the error state, but its type has been u32.
The type has now been changed to i32, and the variable is set to -1 in
the default_error_header function. Therefore, the MovieClip error state
is now fully implemented.
Other connected functions and variables like SwfMovie::uncompressed_len
or MovieClip::total_bytes have been adjusted to this type change. Code
has been adjusted if needed where this value is used.
Backends that need synchronous preload behavior now explicitly ask for it as follows:
* `tests` - repeatedly call `preload` in a loop with an exhausted execution limit to stress-test the chunked preload
* `exporter`, `scanner` - synchronous/unlimited preload to match prior behavior
These may change in the future.
Make it a thin abstraction layer over either the `futures` or `wasm-bindgen-futures`
crates, as already done in `render/wgpu/src/uniform_buffer.rs`,
instead of a hand-made single-thread executor.
Ideally this would also be usable on desktop, but I didn't manage to
get `LocalPool` working with `winit` (it needs to post a task to the
`EventLoopProxy` as a wake procedure).
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.
Since forking isn't an option in Rust (and is generally unsafe, incompatible with threads, and more or less not UNIX's best design idea) we instead grab the current binary path and run it again with a different subcommand.
This should allow us to grab all the panics, including uncatchable ones.
Note: this also requires that we introduce an IPC mechanism. I currently decided to have it spit out CSV rows, same as the main `scan` command. This also makes the psuedo-fork subcommand arguably useful on it's own as it will dump timing metrics for each step.
This relies on a proposed serial bridge as per https://github.com/rayon-rs/rayon/issues/858. As that project is licensed the same as Ruffle itself and the submitter intended it to be included in Rayon, I believe it's legal to copy this code.
Rayon's default of 2MB is about half of what the AVM1 recursion limit requires, and I have plenty of memory, so I might as well add some padding for long runs.
This currently fails to scan the entire Flashpoint `localflash` directory because Rust considers stack overflow to be an immediate program termination, no ifs, ands, or buts about it.
