@dalcde Every test fails here, the errors are TypeError: Cannot read property '_PyErr_Occurred' of undefined from pyodide._module._PyErr_Occurred. So the problem is pyodide._module is undefined. Why would that be?? Maybe if we changed pyodide.js like:

  let Module = {};
  Module._module = Module; // add this
  self.Module = Module;

@rth @dalcde The tests failed because now it correctly fails test_numpy.py::test_python2js_numpy_dtype which leaves the error indicator set.

I can merge this after the tests from #1111 are tidied up

Okay, will do.

Oops should have merged first.

Also, the array.array test uses Q as the format which means 64 bit integers. Javascript has a BigUint64Array. Ideally it would be good to make a memoryview with a more definitely invalid format to make the test more forward compatible.

For whatever inexplicable reason the tests seem to be genuinely failing

I will try to figure out what's wrong tomorrow.

I also added a second test with the "u" format, which is the only alternative to "Q" for a format which triggers the bug and can be made with array.array

(numpy seems to make all sorts of other exotic format strings, from C I could make anything I want, but this seems good enough.)

Now the docs is failing because files.pythonhosted.org is returning a 502...
