Remove sleeps and replace with events. (This may fail on some slow platforms, but we can fix those cases which should be relatively isolated and easier to find now.) Move two test cases that didn't require a server to be started to a separate TestCase. These tests were taking 3 seconds which is what the timeout was set to. ........ r61082 | christian.heimes | 2008-02-26 09:18:11 +0100 (Tue, 26 Feb 2008) | 1 line The contains function raised a gcc warning. The new code is copied straight from py3k. ........ r61084 | neal.norwitz | 2008-02-26 09:21:28 +0100 (Tue, 26 Feb 2008) | 3 lines Add a timing flag to Trace so you can see where slowness occurs like waiting for socket timeouts in test_smtplib :-). ........ r61086 | christian.heimes | 2008-02-26 18:23:51 +0100 (Tue, 26 Feb 2008) | 3 lines Patch #1691070 from Roger Upole: Speed up PyArg_ParseTupleAndKeywords() and improve error msg My tests don't show the promised speed up of 10%. The code is as fast as the old code for simple cases and slightly faster for complex cases with several of args and kwargs. But the patch simplifies the code, too. ........ r61087 | georg.brandl | 2008-02-26 20:13:45 +0100 (Tue, 26 Feb 2008) | 2 lines #2194: fix some typos. ........ r61088 | raymond.hettinger | 2008-02-27 00:40:50 +0100 (Wed, 27 Feb 2008) | 1 line Add itertools.combinations(). ........ r61089 | raymond.hettinger | 2008-02-27 02:08:04 +0100 (Wed, 27 Feb 2008) | 1 line One too many decrefs. ........ r61090 | raymond.hettinger | 2008-02-27 02:08:30 +0100 (Wed, 27 Feb 2008) | 1 line Larger test range ........ r61091 | raymond.hettinger | 2008-02-27 02:44:34 +0100 (Wed, 27 Feb 2008) | 1 line Simply the sample code for combinations(). ........
