[issue32866] zipimport loader.get_data() requires absolute zip file path

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

I believe this bug does not affect Python 3.8:

(Using a Python 3.8 virtualenv):

% python demo.pyz 
Reading: resource.txt
Length: 19
% python `pwd`/demo.pyz 
Reading: resource.txt
Length: 19

I think it's too risky (and too much work, given it would have to be ported to 
the C implementation of zipimport) to change this in earlier Pythons.  So, 
closing.

zipimport has been rewritten in pure Python (issue25711).

[issue32866] zipimport loader.get_data() requires absolute zip file path

[Barry A. Warsaw]

New submission from Barry A. Warsaw :

Over in https://gitlab.com/python-devs/importlib_resources/issues/48 we have a 
report of a FileNotFoundError when trying to read a resource from a zip file.  
Upon further debugging, I found that zipimport's loader.get_data() raises an 
unexpected OSError.  Interestingly, if the path to the zip file is absolute, 
everything works as expected, but if the path is relative, then it fails.

There's probably a missing abspath() in there somewhere, but as zipimport is 
written in C, I really didn't spend much time digging around in gdb.
