From a79ec1c6cd80b96294f3f4dcf72eb2aea5a8da1d Mon Sep 17 00:00:00 2001 From: david-sarah Date: Thu, 5 Aug 2010 22:00:51 -0700 Subject: [PATCH] test_util.py: use SHA-256 from pycryptopp instead of MD5 from hashlib (for uses in which any hash will do), since hashlib was only added to the stdlib in Python 2.5. --- NEWS | 1 + src/allmydata/test/test_util.py | 16 ++++++++-------- 2 files changed, 9 insertions(+), 8 deletions(-) diff --git a/NEWS b/NEWS index f1be66dc..050e79c0 100644 --- a/NEWS +++ b/NEWS @@ -8,6 +8,7 @@ created by other Tahoe-LAFS versions.
