svn+ssh://pythondev@svn.python.org/python/trunk (Note: some conflicts in the PCbuild9 directory reverted. Sorry Christian!) ........ r59120 | christian.heimes | 2007-11-22 03:21:16 -0800 (Thu, 22 Nov 2007) | 3 lines Backport of the PCbuild9 directory from the py3k branch. I've finished the last task for the PCbuild9 directory today. I don't think there is much left to do. Now you can all play around with the shiny new VS 2008 and try the PGO builds. I was able to get a speed improvement of about 10% on py3k. Have fun! :) ........ r59126 | brett.cannon | 2007-11-22 16:06:51 -0800 (Thu, 22 Nov 2007) | 2 lines Fix a bug in the test for using __loader__.get_data(). ........ r59131 | christian.heimes | 2007-11-22 23:05:03 -0800 (Thu, 22 Nov 2007) | 1 line Backport of PCbuild9 fixes from py3k r59130 ........ r59132 | christian.heimes | 2007-11-23 01:10:36 -0800 (Fri, 23 Nov 2007) | 2 lines Applied patch #1754273 and #1754271 from Thomas Glee The patches are adding deprecation warnings for back ticks and <> ........ r59133 | christian.heimes | 2007-11-23 04:12:02 -0800 (Fri, 23 Nov 2007) | 2 lines Fixed problems in the last commit. Filenames and line numbers weren't reported correctly. Backquotes still don't report the correct file. The AST nodes only contain the line number but not the file name. ........ r59134 | christian.heimes | 2007-11-23 04:16:35 -0800 (Fri, 23 Nov 2007) | 1 line How did the comment get there? ........ r59135 | christian.heimes | 2007-11-23 05:25:31 -0800 (Fri, 23 Nov 2007) | 1 line And yet another fix for the patch. Paul Moore has send me a note that I've missed a declaration. The additional code has moved the declaration in the middle of the block. ........ r59136 | andrew.kuchling | 2007-11-23 05:37:39 -0800 (Fri, 23 Nov 2007) | 1 line Add item ........ r59137 | skip.montanaro | 2007-11-23 09:08:35 -0800 (Fri, 23 Nov 2007) | 2 lines Make trace and doctest play nice together (issue 1429818).

This avoids a lot of conversions, and achieves a speedup of 40%. The API remains intact. Thanks Mark Dickinson. ........ r59146 | facundo.batista | 2007-11-23 10:14:50 -0800 (Fri, 23 Nov 2007) | 3 lines Test cases from Cowlishaw, v2.57.

I'm wonder why I was trying to add the filename to the node all the time. The compiling struct is more obvious. ........ r59158 | christian.heimes | 2007-11-23 17:53:59 -0800 (Fri, 23 Nov 2007) | 2 lines Backport of fixes from py3k branch svn merge -r59131:HEAD ../../py3k/PCbuild9/ . ........ r59159 | skip.montanaro | 2007-11-23 20:29:08 -0800 (Fri, 23 Nov 2007) | 1 line revert change that breaks test_doctest (which I forgot to run - sorry) ........ r59162 | skip.montanaro | 2007-11-23 20:31:15 -0800 (Fri, 23 Nov 2007) | 1 line revert ........ r59164 | georg.brandl | 2007-11-24 03:31:46 -0800 (Sat, 24 Nov 2007) | 3 lines #1344: document that you need to open std{in,out,err} with PIPE if you want communicate() to work as described. ........ r59165 | georg.brandl | 2007-11-24 03:39:13 -0800 (Sat, 24 Nov 2007) | 2 lines #1467: fix documentation for TestResult.add{Error,Failure}. ........ r59166 | georg.brandl | 2007-11-24 03:42:14 -0800 (Sat, 24 Nov 2007) | 2 lines #1355: remove mention of PyXML from xml.dom docs. ........ r59169 | amaury.forgeotdarc | 2007-11-24 05:20:22 -0800 (Sat, 24 Nov 2007) | 2 lines Warning "<> not supported in 3.x" should be enabled only when the -3 option is set. ........ r59170 | amaury.forgeotdarc | 2007-11-24 05:44:17 -0800 (Sat, 24 Nov 2007) | 3 lines Issue #1445: Fix a SystemError when accessing the ``cell_contents`` attribute of an empty cell object.
