bpo-1635741: Port _random to multiphase initialization (GH-23359)

bpo-40286: Remove C implementation of Random.randbytes() (GH-19797) 
Remove _random.Random.randbytes(): the C implementation of
randbytes(). Implement the method in Python to ease subclassing:
randbytes() now directly reuses getrandbits().

bpo-40286: Makes simpler the relation between randbytes() and getrandbits() (GH-19574) 2020-04-17 23:51:28 +03:00

bpo-40282: Allow random.getrandbits(0) (GH-19539) 2020-04-17 19:32:14 +02:00
Victor Stinner 1a1bd2e238
bpo-40302: Replace PY_INT64_T with int64_t (GH-19573) 
* Replace PY_INT64_T with int64_t
* Replace PY_UINT32_T with uint32_t
* Replace PY_UINT64_T with uint64_t

sha3module.c no longer checks if PY_UINT64_T is defined since it's
always defined and uint64_t is always available on platforms
supported by Python.

bpo-40286: Add randbytes() method to random.Random (GH-19527) 
Add random.randbytes() function and random.Random.randbytes()
method to generate random bytes.

Modify secrets.token_bytes() to use SystemRandom.randbytes()
rather than calling directly os.urandom().

Rename also genrand_int32() to genrand_uint32(), since it returns an
unsigned 32-bit integer, not a signed integer.

The _random module is now built with Py_BUILD_CORE_MODULE defined.

bpo-38075: Fix random_seed(): use PyObject_CallOneArg() (GH-18897) 
Fix the random.Random.seed() method when a bool is passed as the
seed.

PyObject_Vectorcall() was misused: use PyObject_CallOneArg() instead.

bpo-39245: Switch to public API for Vectorcall (GH-18460) 
The bulk of this patch was generated automatically with:

    for name in \
        PyObject_Vectorcall \
        Py_TPFLAGS_HAVE_VECTORCALL \
        PyObject_VectorcallMethod \
        PyVectorcall_Function \
        PyObject_CallOneArg \
        PyObject_CallMethodNoArgs \
        PyObject_CallMethodOneArg \
    ;
    do
        echo $name
        git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g"
    done

    old=_PyObject_FastCallDict
    new=PyObject_VectorcallDict
    git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g"

and then cleaned up:

- Revert changes to in docs & news
- Revert changes to backcompat defines in headers
- Nudge misaligned comments

Dino Viehland 04f0bbfbed bpo-38075: Port _randommodule.c to PEP-384 (GH-15798) 
- Migrate `Random_Type` to `PyType_FromSpec`
- To simulate an old use of `PyLong_Type.tp_as_number->nb_absolute`, I added
  code to the module init function to stash `int.__abs__` for later
  use. Ideally we'd use `PyType_GetSlot()` instead, but it doesn't currently
  work for static types in CPython, and implementing it just for this case
  doesn't seem worth it.
- Do exact check for long and dispatch to PyNumber_Absolute, use vector call when not exact.

Siddhesh Poyarekar 55edd0c185 bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030) 
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.

until the system urandom entropy pool is initialized to increase the security.

This change is part of the PEP 524.
