From 79f5ba9bf7656972dd988508eff9465562dde42c Mon Sep 17 00:00:00 2001 From: Vratko Polak Date: Mon, 4 May 2020 13:05:26 +0200 Subject: Separate files needing GPL license + Keep apache license for now, until this is completed: https://wiki.fd.io/view/TSC/Relicensing_Procedure + Add utilities for switching license comment blocks. - They do not preserve attributes, so executable flag is lost. + Move the affected files to GPL/. + Update paths so files are executed from the new location. + Change the way scripts are started to do not require executable flag. + Employ OptionString when constructing longer command lines. + Move also PacketVerifier.py and TrafficScriptArg.py as they are linked with traffic scripts. + That means the two files are outside "resources" package tree now. + Added __init__.py files so relative imports work in new package tree. + Start traffic scripts as python modules to allow relative imports. + Once again needed because they are outside the default PYTHONPATH.
