[brettcannon]

This issue is to track the silencing of DeprecationWarning by default.

To start a patch has been attached against trunk which silences
DeprecationWarning. Documentation changes are still needed, though.

[brettcannon]

New patch that includes proposed doc changes.

[pitrou]

Just FYI, there are tabs in your spaces in _warnings.c.

[ezio-melotti]

The second paragraph ("There is also the issue...") is IMO redundant, especially the third sentence ("But because Python is an interpreted language...").

[briancurtin]

warnings_rst_reword.diff proposes slightly different wording on the "Updating Code..." section of documentation.

[brettcannon]

Thanks for the feedback, everyone. The tabs have been fixed in the source. As for the docs, I moved the explanation as to why the warnings are silenced to the end of the section and chopped the "compilation" reasoning as it is not the critical reason for the silencing.

[briancurtin]

The wording of the documentation flows and is arranged better than before.

However, there is a test failure: test_exceptions.testDeprecatedMessageAttribute depends on the deprecation warning always occuring.
@unittest.skipIf(DeprecationWarning in [filter[2] for filter in warnings.filters], "DeprecationWarning disabled") or something like that could avoid it.

[brettcannon]

Latest patch adds fixes to test_exceptions test_ascii_formatd to pass.

[brettcannon]

Committed in r77402. I am going to wait to see if any doc changes occur before I commit in py3k.

For historical reasons, here is the thread that hashed out the reasonsing: http://mail.python.org/pipermail/stdlib-sig/2009-November/000789.html

And thanks to everyone who helped out with this!

Has enough time elapsed yet for py3k merging?

Sure. I will try to do it before or at PyCon.
