gh-93172: Remove unnecessary "if"s in binascii_a2b_qp_impl() from Modules/binascii.c (GH-93181) 2022-05-25 11:38:47 -04:00

bpo-38256: Fix binascii.crc32() when inputs are 4+GiB (GH-32000)
When compiled with `USE_ZLIB_CRC32` defined (`configure` sets this on POSIX systems), `binascii.crc32(...)` failed to compute the correct value when the input data was >= 4GiB. Because the zlib crc32 API is limited to a 32-bit length.

This lines it up with the `zlib.crc32(...)` implementation that doesn't have that flaw.

**Performance:** This also adopts the same GIL releasing for larger inputs logic that `zlib.crc32` has, and causes the Windows build to always use zlib's crc32 instead of our slow C code as zlib is a required build dependency on Windows.

bpo-43974: Move Py_BUILD_CORE_MODULE into module code (GH-29157)
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.

bpo-35134: Add Include/cpython/longobject.h (GH-29044)
Move Include/longobject.h non-limited API to a new
Include/cpython/longobject.h header file.

Move the following definitions to the internal C API:

* _PyLong_DigitValue

bpo-45434: Remove pystrhex.h header file (GH-28923)
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-45085: Remove the binhex module (GH-28117)
The binhex module, deprecated in Python 3.9, is now removed. The
following binascii functions, deprecated in Python 3.9, are now also
removed:

* a2b_hqx(), b2a_hqx();
* rlecode_hqx(), rledecode_hqx().

The binascii.crc_hqx() function remains available.

bpo-43086: Add handling for out-of-spec data in a2b_base64 (GH-24402)
binascii.a2b_base64 gains a strict_mode= parameter. When enabled it will raise an
error on input that deviates from the base64 spec in any way.  The default remains
False for backward compatibility.

bpo-39824: module_traverse() don't call m_traverse if md_state=NULL (GH-18738)
Extension modules: m_traverse, m_clear and m_free functions of
PyModuleDef are no longer called if the module state was requested
but is not allocated yet. This is the case immediately after the
module is created and before the module is executed (Py_mod_exec
function). More precisely, these functions are not called if m_size is
greater than 0 and the module state (as returned by
PyModule_GetState()) is NULL.

Extension modules without module state (m_size <= 0) are not affected.

bpo-22385: Support output separators in hex methods. (#13578)
* bpo-22385: Support output separators in hex methods.

Also in binascii.hexlify aka b2a_hex.

The underlying implementation behind all hex generation in CPython uses the
same pystrhex.c implementation.  This adds support to bytes, bytearray,
and memoryview objects.

The binascii module functions exist rather than being slated for deprecation
because they return bytes rather than requiring an intermediate step through a
str object.

This change was inspired by MicroPython which supports sep in its binascii
implementation (and does not yet support the .hex methods).
