From 2ba535acb1f03fb7d1bdb57e4173d55661d300da Mon Sep 17 00:00:00 2001 From: "W. Trevor King" Date: Thu, 3 Dec 2009 21:19:54 -0500 Subject: Added libbe.TESTING (defaults to False). This flag allows us to skip unittest and testsuite declaration if we woln't need them. It speeds up simple be calls a suprising amount. With Testing=True (the old behavior): wking@thor:be.wtk$ time ./be > /dev/null real 0m0.393s user 0m0.340s sys 0m0.048s With TESTING=False (the new behavior): be.wtk$ time ./be > /dev/null real 0m0.216s user 0m0.152s sys 0m0.064s This adjustment was inspired by Jakub Wilk's Debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=559295 --- libbe/properties.py | 511 ++++++++++++++++++++++++++-------------------------- 1 file changed, 257 insertions(+), 254 deletions(-) (limited to 'libbe/properties.py') diff --git a/libbe/properties.py b/libbe/properties.py index 54375b4..f756ff0 100644 --- a/libbe/properties.py +++ b/libbe/properties.py @@ -30,7 +30,10 @@ for more information on decorators. import copy import types -import unittest + +import libbe +if libbe.TESTING == True: + import unittest class ValueCheckError (ValueError): @@ -383,257 +386,257 @@ def change_hook_property(hook, mutable=False, default=None): return funcs return decorator -
