From a9047a722ba5de38e7c1d762ffcfb74c36725fe2 Mon Sep 17 00:00:00 2001 From: Andrew Cooper Date: Mon, 11 Mar 2019 19:18:40 +0000 Subject: [PATCH] tools/xen-foreign: Update python scripts to be Py3 compatible The issues are: * dict.has_key() was completely removed in Py3 * dict.keys() is an iterable rather than list in Py3, so .sort() doesn't work. * list.sort(cmp=) was deprecated in Py2.4 and removed in Py3. The has_key() issue is trivially fixed by switching to using the in keyword. The sorting issue could be trivially fixed, but take the opportunity to improve the code. The reason for the sorting is to ensure that "unsigned long" gets replaced before "long", and the only reason sorting is necessary is because inttypes[arch] is needlessly a dictionary. Update inttypes[arch] to be a list of tuples rather than a dictionary, and process them in list order.
