[Bug] File descriptors aren't supported in the FS layer #359
Description
Describe the bug
Our FS layer doesn't support file descriptors at the moment, which causes issues in some cases (particularly ESLint).
To fix that, we need to:
- Create a new type in path.ts,
FSPath<T>, which isT | number - Use
FSPath<NativePath>in thefsfunctions that accepts file descriptors - Update ProxiedFS to accept/return a
FSPath<T>instead ofPath - Update ProxiedFS to not call
mapFromBase/mapToBaseon fds
To Reproduce
const {openSync, readFileSync, writeFileSync} = require(`fs`);
writeFileSync(`foo`, `hello world`);
const fd = openSync(`foo`, `r`);
expect(() => readFileSync(fd)).not.toThrow();Additional context
