I think we should propagate the errors and not ignore them

@amrbashir - with a try / finally block, errors will still propagate as expected, no? Also, I think we should release the lock and close the file handle, regardless of an error, so it seems like finally is the right place for this. Let me know your thoughts.
function test() {
try {
throw new Error("Oops!");
} finally {
console.log("Finally block runs!");
}
}
test(); // Logs "Finally block runs!", then throws "Oops!"There was a problem hiding this comment.
this does work indeed, thank you

Thank you |
The
writeFilefunction accepts aReadableStream, however, under macOS this does not work since the built-in webview does not have async iterator support. See Safari's compatibility for more info.This PR converts the code to a manual read while-loop instead, fixing support for macOS.
Note: I have not tested this across all platforms. Perhaps @amrbashir could check this, if possible? 🙏
