| | | | | | Also remove some now unused variables, and add comments clarifying the possible outputs of the parsing section of _Py_dg_strtod. Thanks Eric Smith for reviewing.

| | | | | | | | Py3K warnings are DeprecationWarning by default this was causing -3 to essentially be a no-op. Now DeprecationWarning is only silenced if -3 is not used. Closes issue #7700. Thanks Ezio Melotti and Florent Xicluna for patch help.

* Fix off-by-one error introduced in r77483. I have a test for this, but it ↵Mark Dickinson2010-01-141-2/+2

* DeprecationWarning is now silent by default.Brett Cannon2010-01-101-20/+23
| | | | | | | | | | | | This was originally suggested by Guido, discussed on the stdlib-sig mailing list, and given the OK by Guido directly to me. What this change essentially means is that Python has taken a policy of silencing warnings that are only of interest to developers by default. This should prevent users from seeing warnings which are triggered by an application being run against a new interpreter before the app developer has a chance to update their code. Closes issue #7319. Thanks to Antoine Pitrou, Ezio Melotti, and Brian Curtin for helping with the issue.
