[New-bugs-announce] [issue37641] Embeddable distribution pyc filenames show build machine location

[Bill Collins]

New submission from Bill Collins <bilbocollins at gmail.com>:

pyc files within the embeddable zip are compiled with their filename as the temporary directory in which they are compiled. Thus, stack traces will appear as (e.g.) D:\obj\windows-release\37win32_Release\msi_python\zip_win32\image.py, which is a little surprising and not obvious that it's actually from email/mime/image.py.

We currently work around this by updating the pyc files before shipping to be relative paths to Lib/; however, fixing this upstream would appear to be as simple as passing through the dest from _write_to_zip to _py_temp_compile (https://github.com/python/cpython/blob/21a92f8cda525d25a165b773fbe1bfffd303a000/PC/layout/main.py#L302) to be passed into _compile_one_py
