Any reason not to set the zip_safe flag in setup.py? This was addressed in #538 but the flag was lost at some point when setup.py was refactored.

[Russell Keith-Magee]

Yes, there is a reason - Django uses distutils, not setuptools. zip_safe is a setuptools option; if you apply the provided patch and run python setup.py install , you get the warning {{{UserWarning: Unknown distribution option: 'zip_safe'
}}}

[bhuztez]

the zip_egg_fixed patch for #14087 can fix this.

Django has since switched to setuptools in 1.7 and zip_safe=False was added as part of that change: 66f546b90624297858b0f958abbe5c2b3e8bdffb.
