[New-bugs-announce] [issue24794] PyZipFile mixes compiled files from different python versions.

[Amund Hov]

New submission from Amund Hov:

In my project I have a mixture of scripts using Python 2.7 and 3.4.
Some of the scripts using python 3.4 are packaged into archives using
PyZipFile.

Through some combination I ended up with 2.7 compiled packages in my archive when packaging using python 3.4. In combination with issue 24792 "zipimporter masks import errors" this led to many grey hairs figuring out why my packaging scripts suddenly broke.

Are there sufficient provisions in PyZipFile to prevent this? It seems it will happily mix compiled files with differing magic bytes.
