[issue24792] zipimporter masks import errors
New submission from Amund Hov:
Due to mixed version .pyc files in my zipped python application I was getting
inconsistent loading of certain packages.
E.g.
n [4]: zf.find_module('kitconsole')
Out[4]:
In [5]: zf.load_module('kitconsole')
---
ZipImportErrorTraceback (most recent call last)
in ()
> 1 zf.load_module('kitconsole')
ZipImportError: can't find module 'kitconsole'
Unpacking the archive and doing the import from the file system revealed the
real issue, ImportError: Bad Magic Number.
As an end user it was confusing that zipimporter reported being able to find
the module in find_module(), but not in load_module(). Is it possible to have
load_module provide a better error message when import fails? The wording now
does not give any hints when searching the bug-tracker / Google.

[issue24794] PyZipFile mixes compiled files from different python versions.
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. -- messages: 248024 nosy: Amund Hov priority: normal severity: normal status: open title: PyZipFile mixes compiled files from different python versions. type: behavior ___ Python tracker <http://bugs.python.org/issue24794> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
