Thanks Neal. ........ r61051 | mark.dickinson | 2008-02-24 19:12:36 +0100 (Sun, 24 Feb 2008) | 2 lines Remove duplicate 'import re' in decimal.py ........ r61052 | neal.norwitz | 2008-02-24 19:47:03 +0100 (Sun, 24 Feb 2008) | 11 lines Create a db_home directory with a unique name so multiple users can run the test simultaneously. The simplest thing I found that worked on both Windows and Unix was to use the PID. It's unique so should be sufficient. This should prevent many of the spurious failures of the automated tests since they run as different users. Also cleanup the directory consistenly in the tearDown methods. It would be nice if someone ensured that the directories are always created with a consistent name. ........ r61057 | christian.heimes | 2008-02-24 23:48:05 +0100 (Sun, 24 Feb 2008) | 2 lines Added dependency rules for Objects/stringlib/*.h stringobject, unicodeobject and the two formatters are rebuild whenever a header files changes ........
