Document the temporary frozenset swap in __contains__(), remove(), and discard(). ........ r62887 | brett.cannon | 2008-05-08 14:50:51 -0500 (Thu, 08 May 2008) | 5 lines Make test.test_support.catch_warning() take an argument specifying if any triggered warnings should be captured. This allows the context manager to be used to just prevent the internal state of the 'warnings' framework and thus allow triggered warnings to be displayed. ........ r62892 | brett.cannon | 2008-05-08 15:20:24 -0500 (Thu, 08 May 2008) | 4 lines Fix a bug introduced by the addition of the 'record' argument to test.test_support.catch_warning() where showwarning() was not being set properly. ........ r62893 | brett.cannon | 2008-05-08 15:20:54 -0500 (Thu, 08 May 2008) | 2 lines Document the 'record' argument for test.test_support.catch_warning(). ........ r62894 | brett.cannon | 2008-05-08 15:23:06 -0500 (Thu, 08 May 2008) | 4 lines Fix sys.flags to properly expose bytes_warning.
