Antoine Pitrou 4879a963d4 Issue #18756: os.urandom() now uses a lazily-opened persistent file descriptor, so as to avoid using many file descriptors when run in parallel from multiple threads. 2013-08-31 00:26:02 +02:00

Antoine Pitrou 95b21460ee Issue #18756: Improve error reporting in os.urandom() when the failure is due to something else than /dev/urandom not existing. 2013-08-16 20:49:32 +02:00
Antoine Pitrou ec34ab5010 Issue #18756: Improve error reporting in os.urandom() when the failure is due to something else than /dev/urandom not existing. 2013-08-16 20:44:38 +02:00
Martin v. Löwis 3f50bf652b Drop support for Windows 2000; allow any XP API (but not Vista+).
Drop SDK version configuration for Tk compilation, to not bind it to W2k
anymore. Binding it to XP would conflict with Tk's own binding of tkMenu to W2k.

Georg Brandl 2daf6ae249 Issue #13703: add a way to randomize the hash values of basic types (str, bytes, datetime)
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.

The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.
