* gh-102027: Fix macro name (#102124)Max Bachmann2023-03-221-1/+1
| | | | | This fixes the ssse3 / sse2 detection when sse4 is available. Co-authored-by: Oleg Iarygin <oleg@arhadthedev.net>

* gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code ↵Eric Snow2022-08-112-4/+82
| | | | | | | | | | | | | | | | (gh-95860) We only statically initialize for core code and builtin modules. Extension modules still create the tuple at runtime. We'll solve that part of interpreter isolation separately. This change includes generated code. The non-generated changes are in: * Tools/clinic/clinic.py * Python/getargs.c * Include/cpython/modsupport.h * Makefile.pre.in (re-generate global strings after running clinic) * very minor tweaks to Modules/_codecsmodule.c and Python/Python-tokenize.c All other changes are generated code (clinic, global strings).

* bpo-43974: Move Py_BUILD_CORE_MODULE into module code (GH-29157)Christian Heimes2021-10-223-0/+12
| | | | | | | | | | | | | | setup.py no longer defines Py_BUILD_CORE_MODULE. Instead every module defines the macro before #include "Python.h" unless Py_BUILD_CORE_BUILTIN is already defined. Py_BUILD_CORE_BUILTIN is defined for every module that is built by Modules/Setup. The PR also simplifies Modules/Setup. Makefile and makesetup already define Py_BUILD_CORE_BUILTIN and include Modules/internal for us. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45434: Remove pystrhex.h header file (GH-28923)Victor Stinner2021-10-132-2/+2
| | | | | | | | | | | | | | | Move Include/pystrhex.h to Include/internal/pycore_strhex.h. The header file only contains private functions. The following C extensions are now built with Py_BUILD_CORE_MODULE macro defined to get access to the internal C API: * _blake2 * _hashopenssl * _md5 * _sha1 * _sha3 * _ssl * binascii

* bpo-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-262-52/+2

* bpo-40024: Update C extension modules to use PyModule_AddType() (GH-19119)Dong-hee Na2020-03-241-8/+2
| | | | | | Update _asyncio, _bz2, _csv, _curses, _datetime, _io, _operator, _pickle, _queue, blake2, multibytecodec and overlapped C extension modules to use PyModule_AddType().
* bpo-39573: Add Py_SET_TYPE() function (GH-18394)Victor Stinner2020-02-071-2/+2

* bpo-9216: Add usedforsecurity to hashlib constructors (GH-16044)Christian Heimes2019-09-134-20/+44
| | | | | 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. Contributed and Signed-off-by: Christian Heimes christian@python.org

* bpo-33729: Fix issues with arguments parsing in hashlib. (GH-8346)Serhiy Storchaka2018-07-314-120/+120
| | | | | | | | | | | | | | | | | | | | | | | | * 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)Jack O'Connor2017-11-032-4/+8
| | | | | | | | | | | | 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. See https://github.com/BLAKE2/libb2/issues/12.
* Remove nested comments in blake2 (#4173)Lars Viklund2017-11-011-2/+4
| | | | | | | | | | | Replace occurence of nested comments in blake2 reference implementation with preprocessor directive for disabling unused code. `blake2s-load-xop.h` is conditionally pulled in only on chips with XOP support, among others the AMD Bulldozer. The malformed comments in the source file breaks the build of `hashlib`'s `_blake2` on GCC 6.3.0. Official reference code on github uses `#if` so this change should be uncontroversial.
* fixes bpo-31834: Use optimized code for BLAKE2 only with SSSE3+ (#4066)Michał Górny2017-10-242-2/+6
| | | | | | | | | | | | | | | | Rework the code choosing BLAKE2 code paths from using the optimized variant on all x86_64 machines to using it when SSSE3 or better supported instructions sets are available. Firstly, this solves the problem of using pure SSE2 code path on x86_64 machines. As reported in the bug, this code is slower than the reference code on all tested x86_64 machines. Furthermore, on Athlon64 that lacks SSSE3, it is even 2.5 times slower than the reference code! Checking for SSSE3 therefore ensures that the optimized implementation will only be used when it has a chance of performing better. Secondly, this makes it possible to use SSSE3+ optimizations on 32-bit x86 systems. This allows for even 2 times speed gain on modern 32-bit x86 systems (tested in a 32-bit chroot).
