bpo-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)

2020-12-01T09:37:39+00:00

No longer use deprecated aliases to functions:

* Replace PyObject_MALLOC() with PyObject_Malloc()
* Replace PyObject_REALLOC() with PyObject_Realloc()
* Replace PyObject_FREE() with PyObject_Free()
* Replace PyObject_Del() with PyObject_Free()
* Replace PyObject_DEL() with PyObject_Free()

bpo-1635741: Port _blake2 module to multi-phase init (GH-21856)

2020-09-02T09:45:13+00:00

Port the _blake2 extension module to the multi-phase
initialization API (PEP 489).

bpo-40268: Remove explicit pythread.h includes (#19529)

2020-04-15T00:04:42+00:00

Remove explicit pythread.h includes: it is always included
by Python.h.

bpo-9216: Add usedforsecurity to hashlib constructors (GH-16044)

2019-09-13T00:30:00+00:00

The usedforsecurity keyword only argument added to the hash constructors is useful for FIPS builds and similar restrictive environment with non-technical requirements that legacy algorithms be forbidden by their implementations without being explicitly annotated as not being used for any security related purposes.  Linux distros with FIPS support benefit from this being standard rather than making up their own way(s) to do it.

bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async (GH-13464)

2019-05-31T02:13:39+00:00

Automatically replace
tp_print -> tp_vectorcall_offset
tp_compare -> tp_as_async
tp_reserved -> tp_as_async

Fix misleading mentions of tp_size in comments (GH-9093)

2018-09-10T16:46:08+00:00

Many type object initializations labeled a field "tp_size" in the
comment, but the name of that field is tp_basicsize.

bpo-33729: Fix issues with arguments parsing in hashlib. (GH-8346)

2018-07-31T06:50:16+00:00

* help(hashlib) didn't work because of incorrect module name in blake2b and
  blake2s classes.
* Constructors blake2*(), sha3_*(), shake_*() and keccak_*() incorrectly
  accepted keyword argument "string" for binary data, but documented as
  accepting the "data" keyword argument. Now this parameter is positional-only.
* Keyword-only parameters in blake2b() and blake2s() were not documented as
  keyword-only.
* Default value for some parameters of blake2b() and blake2s() was None,
  which is not acceptable value.
* The length argument for shake_*.digest() was wrapped out to 32 bits.
* The argument for shake_128.digest() and shake_128.hexdigest() was not
  positional-only as intended.
* TypeError messages for incorrect arguments in all constructors sha3_*(),
  shake_*() and keccak_*() incorrectly referred to sha3_224.

Also made the following enhancements:

* More accurately specified input and result types for strings, bytes and
  bytes-like objects.
* Unified positional parameter names for update() and constructors.
* Improved formatting.

bpo-31933: fix blake2 multi-byte params on big endian platforms (#4250)

2017-11-03T19:02:41+00:00

All Blake2 params have to be encoded in little-endian byte order. For
the two multi-byte integer params, leaf_length and node_offset, that
means that assigning a native-endian integer to them appears to work on
little-endian platforms, but gives the wrong result on big-endian. The
current libb2 API doesn't make that very clear, and @sneves is working
on new API functions in the GH issue above. In the meantime, we can work
around the problem by explicitly assigning little-endian values to the
parameter block.
