Antoine Pitrou f9d0b1256f Issue #13390: New function :func:`sys.getallocatedblocks()` returns the number of memory blocks currently allocated. 
Also, the ``-R`` option to regrtest uses this function to guard against memory allocation leaks.

Benjamin Peterson 2afe6aeae8 perform yield from delegation by repeating YIELD_FROM opcode (closes #14230) 
This allows generators that are using yield from to be seen by debuggers. It
also kills the f_yieldfrom field on frame objects.

Patch mostly from Mark Shannon with a few tweaks by me.

Stefan Krah 9a2d99e28a - Issue #10181: New memoryview implementation fixes multiple ownership 
and lifetime issues of dynamically allocated Py_buffer members (#9990)
  as well as crashes (#8305, #7433). Many new features have been added
  (See whatsnew/3.3), and the documentation has been updated extensively.
  The ndarray test object from _testbuffer.c implements all aspects of
  PEP-3118, so further development towards the complete implementation
  of the PEP can proceed in a test-driven manner.

  Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
  and many ideas.

- Issue #12834: Fix incorrect results of memoryview.tobytes() for
  non-contiguous arrays.

- Issue #5231: Introduce memoryview.cast() method that allows changing
  format and shape without making a copy of the underlying memory.

Georg Brandl 2fb477c0f0 Merge 3.2: Issue #13703 plus some related test suite fixes. 2012-02-21 00:33:36 +01:00
Georg Brandl 09a7c72cad Merge from 3.1: 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.
