Also fix jit_empty_cache when callbacks are pending (fixes#53)
This is also a preparation for setting WASM_TABLE_SIZE to a low value to
work around memory limitations in browsers.
Simplifies both the filestorage.js code as well as the starter.js code
that uses these FileStorage classes.
Now, the ServerFileStorageWrapper decorates the other FileStorage
classes by loading from the server when the file is not available.
Moreover, the previous starter.js was incorrectly passing the `baseurl`
parameter (it was passing it when baseurl was not defined nor needed).
Fallback logic is moved to the caller's responsibility.
Empty FileStorages and FileStorages that load from the server are
separated into different classes. This is to avoid faults where the
caller of the constructor forgets to pass in a `baseurl` parameter and
leads to some confusing bug.
Uses MemoryFileStorage as a fallback when:
- v86 is used in a browserless environment, e.g. NodeJS
- browser doesn't support indexedDB
- opening indexedDB fails
- existing database is a newer version
- existing database is an old version and is under use - blocking
current v86 instance to connect to it.
The "// jshint ignore:line" comments are pretty messy, so squint your eyes.
They're systematically placed, so we can regex it out when jshint's
new version finally arrives.
Using async/await instead of callbacks due to callback hell, and it also
helps minimising the diff)
This commit contains the final changes requires for porting all C code
to Rust and from emscripten to llvm:
- tools/wasm-patch-indirect-function-table.js: A script that rewrites
the wasm generated by llvm to remove the table limit
- tools/rust-lld-wrapper: A wrapper around rust-lld that removes
arguments forced by rustc that break compilation for us
- src/rust/cpu2/Makefile: A monstrosity to postprocess c2rust's output
- gen/generate_interpreter.js: Ported to produce Rust instead of C
- src/rust/*: A few functions and macros to connect the old Rust code
and the new Rust code
- src/*.js: Removes the loading of the old emscripten wasm module and
adapts imports and exports from emscripten to llvm
If mountpoint already exists, then we're silently making its children
inaccessible which may not be what we expected/intended.
Create a new forwarder inode upon mounting.
