python27: Python Frameworks not codesigned in MacOS Sierra

[tcwan (TC Wan)]

I am using a python app which opens a listening socket for network connections, which is intercepted by the MacOS Firewall with the permission dialog "XXX accept incoming connections?" each time the app is executed.

The reason for this behavior is due to the Python Frameworks not having a valid signature

$ codesign -vvv /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app: code object is not signed at all
In architecture: x86_64

To overcome this, the python framework(s) should be codesigned after installation.

$sudo codesign -f -s - /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app

Note the '-' after -s is needed to force codesign to use an ad hoc signature.

After codesigning, the following output is seen:

$ codesign -vvv /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app: valid on disk
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app: satisfies its Designated Requirement

I think the codesigning requirement is true for all versions of Python, not just Python 2.7

I'm still getting this issue. Could we implement this please?
