From 84c95b94075f73e452539e71230537644a4932f8 Mon Sep 17 00:00:00 2001 From: Neal Norwitz Date: Mon, 3 Apr 2006 05:28:31 +0000 Subject: Fix test_pty on OSF/1 (Tru64). The problem is that the newline gets converted to CR CR NL. There may be a way to fix this with tcsetattr, but I couldn't find it. There was a similar problem on IRIX. Just normalize the output and compare that. Will backport. --- Lib/test/test_pty.py | 28 +++++++++++++++++++++++----- 1 file changed, 23 insertions(+), 5 deletions(-) diff --git a/Lib/test/test_pty.py b/Lib/test/test_pty.py index f8ae479..3a90dd8 100644 --- a/Lib/test/test_pty.py +++ b/Lib/test/test_pty.py @@ -18,6 +18,27 @@ else: def debug(msg): pass +def normalize_output(data): + # Some operating systems do conversions on newline.
