Mark Dickinson added the comment: I just wanted to ensure that there wouldn't be any bugs by my patch. Okay, understood. Thanks. Please note that this issue is now closed, though: the 2.3 compatibility workarounds have been dealt with. The use or non-use of dummy_threading has nothing to do with 2.3 compatibility and so is out of scope for the issue. You should feel free to open a new issue if there's a demonstrable problem or demonstrable room for improvement w.r.t. the way dummy threading is handled. (I'm personally not convinced that either of those is true, but others may have different views.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13701 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Do you mean that 'import threading' will always succeed, even on platforms built without thread support? Is this documented somewhere?

Raymond Hettinger raymond.hettin...@gmail.com added the comment: Mark, do you think the C version of decimal is going to happen for 3.3? If so, it make little sense to make any changes at all the current version of the pure python code. Another advantage to leaving the pure python code alone is that it will make maintenance easier if we have to make updates (remember, if the spec gets updated, that will be considered a bug fix and backported). -- priority: normal - low ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13701 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Mark Dickinson dicki...@gmail.com added the comment: Did you have specific changes in mind? While we're still maintaining 2.x and 3.x code in parallel, there's a benefit to not having the versions of decimal.py diverge too much. Given that the 2.3-compatible code isn't actually broken, I'm not sure that there's really that much to be gained by changing it. The ugliest part of the current code is probably the post-application of classmethod instead of using a decorator; I wouldn't object to fixing that. I do agree with the general principle that the 3.x version of decimal.py doesn't need to stay backwards compatible with Python 2.3. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13701 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
