[issue38286] tarfile forgets set sgid when targetpath has it

[Charles Coulombe]

New submission from Charles Coulombe :

An archive that does not have sgid that is extracted in a directory with sgid 
set does not end up having its sgid set since the targetpath is chmod with the 
mode of the tarinfo. (Lib/tarfile.py#L2277) 

For comparison, an archive extracted with tar has the sgid bit set.

I added a patch as attachment to gather comments before making this PR.

[issue21042] ctypes.util.find_library() should return full pathname instead of filename in linux

[Charles Coulombe]

Charles Coulombe  added the comment:

Any update on this issue? 

This would be helpful to HPC systems that don't have libraries installed in 
standard place, and to standardize find_library as well!
