Re: [cx-freeze-users] Problems with inspect.getmodule

[Thomas K. <ta...@gm...>]

I see. I'm not sure there's an easy fix for that: the filename it's
retrieving for the calling code is baked in when it's byte-compiled, i.e.
when cx_Freeze freezes it, while the filename in modulesbyfilename is
calculated at runtime.

Looking up the stack at the calling function is a nasty practice, and I'd
be wary of using any code that does that in production.
