[Distutils] why does easy_install set +x on all .py files?

[Erik Bray]

Hi all,

I've used setuptools for a long time, and yet I've only just noticed
this behavior.  It came up because I wanted nose to run some installed
tests, and it was mysterious as to why it wasn't finding them.  Debug
output from nose revealed the answer: it was skipping searching those
modules because they're exectuable.

That's fine, because I can just add --exe to nose.  But I was
wondering why it is that easy_install sets 0755 on all files?  Why not
preserve the existing executable bit set on the file?

Thanks,
Erik
