These need to get merged into py3k, which has no tests for bin. ........ r60968 | raymond.hettinger | 2008-02-22 20:50:06 +0100 (Fri, 22 Feb 2008) | 1 line Document itertools.product(). ........ r60969 | raymond.hettinger | 2008-02-23 03:20:41 +0100 (Sat, 23 Feb 2008) | 9 lines Improve the implementation of itertools.product() * Fix-up issues pointed-out by Neal Norwitz. * Add extensive comments. * The lz->result variable is now a tuple instead of a list. * Use fast macro getitem/setitem calls so most code is in-line. * Re-use the result tuple if available (modify in-place instead of copy). ........ r60972 | raymond.hettinger | 2008-02-23 05:03:50 +0100 (Sat, 23 Feb 2008) | 1 line Add more comments ........ r60973 | raymond.hettinger | 2008-02-23 11:04:15 +0100 (Sat, 23 Feb 2008) | 1 line Add recipe using itertools.product(). ........ r60974 | facundo.batista | 2008-02-23 13:01:13 +0100 (Sat, 23 Feb 2008) | 6 lines Issue 1881. Increased the stack limit from 500 to 1500. Also added a test for this (and because of this test you'll see in stderr a message that parser.c sends before raising MemoryError). Thanks Ralf Schmitt. ........ r60975 | facundo.batista | 2008-02-23 13:27:17 +0100 (Sat, 23 Feb 2008) | 4 lines Issue 1776581. Minor corrections to smtplib, and two small tests. Thanks Alan McIntyre. ........ r60976 | facundo.batista | 2008-02-23 13:46:10 +0100 (Sat, 23 Feb 2008) | 5 lines Issue 1781. Now ConfigParser.add_section does not let you add a DEFAULT section any more, because it duplicated sections with the rest of the machinery. Thanks Tim Lesher and Manuel Kaufmann. ........
