Python 3's "zipfile" has an annoying bug where the `external_attr` field
|
|
of a ZIP file cannot be set to 0. However, if the original DRMed ZIP has
|
|
that set to 0 then we want the DRM-free ZIP to have that as 0, too.
|
|
See https://github.com/python/cpython/issues/87713
|
|
|
|
We cannot just set the "external_attr" to 0 as the code to save the ZIP
|
|
resets that variable.
|
|
|
|
So, here's a class that inherits from ZipInfo and ensures that EVERY
|
|
read access to that variable will return a 0 ...
