When I run the test suite on OSX (configure; make test) I get unexpected est failures:

6 tests failed:
    test_codecencodings_cn test_codecencodings_hk
    test_codecencodings_jp test_codecencodings_kr
    test_codecencodings_tw

When I run one of these manually I get the following traceback:


./python.exe ../Lib/test/test_codecencodings_cn.py
Traceback (most recent call last):
  File "../Lib/test/test_codecencodings_cn.py", line 11, in <module>
    class Test_GB2312(test_multibytecodec_support.TestBase, unittest.TestCase):
  File "../Lib/test/test_codecencodings_cn.py", line 13, in Test_GB2312
    tstring = test_multibytecodec_support.load_teststring('gb2312')
  File "/Users/ronald/Projects/python/rw/2.7/Lib/test/test_multibytecodec_support.py", line 330, in load_teststring
    from test import cjkencodings_test
ImportError: cannot import name cjkencodings_test


The only reference to cjkencodings_test in the entire 2.7 tree is this import line, there is no module or extension with this name.

I've verified the issue in a fresh download of revision c449d3c3e0da of the 2.7 branch.

I'm on OSX 10.6, but that's not really relevant for this issue.

If I'm using 'hg bisect' correctly (and that's a big if as I haven't used it before) this failure is caused by this patch:

The first bad revision is:
changeset:   70161:1bd697cdd210
branch:      2.7
parent:      70145:978016199be8
user:        Victor Stinner <victor.stinner@haypocalc.com>
date:        Mon May 16 17:16:18 2011 +0200
summary:     Issue #12057: Convert CJK encoding testcase BLOB into multiple text files


And indeed in this revision:

$ ls cjkencodings_test.py 
ls: cjkencodings_test.py: No such file or directory

$ grep cjkencodings_test test_multibytecodec_support.py
    from test import cjkencodings_test
    return cjkencodings_test.teststring[encoding]

Oh oh. I forgot to patch .hgeol and test_multibytecodec_support.py during my "merge" 3.1 (16503022c4b8) -> 2.7 (1bd697cdd210). It should be ok with 83f4c270b27d.

Thank you for your report Ronald.
