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 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.

  Move abc._Abstract into object by adding a new flag Py_TPFLAGS_IS_ABSTRACT,
  which forbids constructing types that have it set. The effect is to speed

  Thread.start() used sleep(0.000001) to make sure it didn't return before the
  new thread had started. At least on my MacBook Pro, that wound up sleeping for
  a full 10ms (probably 1 jiffy). By using an Event instead, we can be absolutely
  certain that the thread has started, and return more quickly (217us).

  Before:
  $  ./python.exe -m timeit -s 'from threading import Thread'  't = Thread(); t.start(); t.join()'
  100 loops, best of 3: 10.3 msec per loop
  $  ./python.exe -m timeit -s 'from threading import Thread; t = Thread()'  't.isAlive()'
  1000000 loops, best of 3: 0.47 usec per loop

  After:
  $  ./python.exe -m timeit -s 'from threading import Thread'  't = Thread(); t.start(); t.join()'
  1000 loops, best of 3: 217 usec per loop
  $  ./python.exe -m timeit -s 'from threading import Thread; t = Thread()'  't.isAlive()'
  1000000 loops, best of 3: 0.86 usec per loop

  To be fair, the 10ms isn't CPU time, and other threads including the spawned
  one get to run during it. There are also some slightly more complicated ways to
  get back the .4us in isAlive() if we want.
