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.

  Make map() and filter() identical to itertools.imap() and .ifilter(),
  respectively.

  I fixed two bootstrap issues, due to the dynamic import of itertools:

  1. Starting python requires that map() and filter() are not used until
     site.py has added build/lib.<arch> to sys.path.
  2. Building python requires that setup.py and distutils and everything
     they use is free of map() and filter() calls.

  Beyond this, I only fixed the tests in test_builtin.py.
  Others, please help fixing the remaining tests that are now broken!
  The fixes are usually simple:
  a. map(None, X) -> list(X)
  b. map(F, X) -> list(map(F, X))
  c. map(lambda x: F(x), X) -> [F(x) for x in X]
  d. filter(F, X) -> list(filter(F, X))
  e. filter(lambda x: P(x), X) -> [x for x in X if P(x)]

  Someone, please also contribute a fixer for 2to3 to do this.
  It can leave map()/filter() calls alone that are already
  inside a list() or sorted() call or for-loop.

  Only in rare cases have I seen code that depends on map() of lists
  of different lengths going to the end of the longest, or on filter()
  of a string or tuple returning an object of the same type; these
  will need more thought to fix.

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Fred Drake 13634cf7a4 This patch addresses two main issues: (1) There exist some non-fatal
errors in some of the hash algorithms. For exmaple, in float_hash and
complex_hash a certain part of the value is not included in the hash
calculation. See Tim's, Guido's, and my discussion of this on
python-dev in May under the title "fix float_hash and complex_hash for
64-bit *nix"

(2) The hash algorithms that use pointers (e.g. func_hash, code_hash)
are universally not correct on Win64 (they assume that sizeof(long) ==
sizeof(void*))

As well, this patch significantly cleans up the hash code. It adds the
two function _Py_HashDouble and _PyHash_VoidPtr that the various
hashing routine are changed to use.

These help maintain the hash function invariant: (a==b) =>
(hash(a)==hash(b))) I have added Lib/test/test_hash.py and
Lib/test/output/test_hash to test this for some cases.
