From 49fd7fa4431da299196d74087df4a04f99f9c46f Mon Sep 17 00:00:00 2001 From: Thomas Wouters Date: Fri, 21 Apr 2006 10:40:58 +0000 Subject: Merge p3yk branch with the trunk up to revision 45595. This breaks a fair number of tests, all because of the codecs/_multibytecodecs issue described here (it's not a Py3K issue, just something Py3K discovers): http://mail.python.org/pipermail/python-dev/2006-April/064051.html Hye-Shik Chang promised to look for a fix, so no need to fix it here. The tests that are expected to break are: test_codecencodings_cn test_codecencodings_hk test_codecencodings_jp test_codecencodings_kr test_codecencodings_tw test_codecs test_multibytecodec This merge fixes an actual test failure (test_weakref) in this branch, though, so I believe merging is the right thing to do anyway. --- Doc/lib/libthreading.tex | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) (limited to 'Doc/lib/libthreading.tex') diff --git a/Doc/lib/libthreading.tex b/Doc/lib/libthreading.tex index 33839a4306..8fb3137744 100644 --- a/Doc/lib/libthreading.tex +++ b/Doc/lib/libthreading.tex @@ -675,3 +675,26 @@ keyword arguments \var{kwargs}, after \var{interval} seconds have passed.
