* GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython ↵Mark Shannon2023-04-124-0/+16
| | | | | | | | | | (GH-103083) * The majority of the monitoring code is in instrumentation.c * The new instrumentation bytecodes are in bytecodes.c * legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs
* gh-103088: Sanitize venv paths when using MSYS or Cygwin Bash (GH-103325)Stanislav Syekirin2023-04-111-1/+1

* gh-87092: move assembler related code from compile.c to assemble.c (#103277)Irit Katriel2023-04-114-8/+16

* gh-101659: Add _Py_AtExit() (gh-103298)Eric Snow2023-04-062-0/+4
| | | | | The function is like Py_AtExit() but for a single interpreter. This is a companion to the atexit module's register() function, taking a C callback instead of a Python one. We also update the _xxinterpchannels module to use _Py_AtExit(), which is the motivating case. (This is inspired by pain points felt while working on gh-101660.)

* gh-103097: Add workaround for Windows ARM64 compiler bug (GH-103098)Steve Dower2023-03-281-0/+9
| | | See https://developercommunity.visualstudio.com/t/Regression-in-MSVC-1433-1434-ARM64-co/10224361 for details of the issue. It only applies to version 14.34.

* gh-102304: Move _Py_RefTotal to _PyRuntimeState (gh-102543)Eric Snow2023-03-202-0/+4
| | | | | | | The essentially eliminates the global variable, with the associated benefits. This is also a precursor to isolating this bit of state to PyInterpreterState. Folks that currently read _Py_RefTotal directly would have to start using _Py_GetGlobalRefTotal() instead. https://github.com/python/cpython/issues/102304

* gh-99108: Import MD5 and SHA1 from HACL* (#102089)Jonathan Protzenko2023-02-222-0/+8
| | | Replaces our fallback non-OpenSSL MD5 and SHA1 implementations with those from HACL* as we've already done with SHA2.
* gh-99108: Refactor _sha256 & _sha512 into _sha2. (#101924)Gregory P. Smith2023-02-162-6/+2
| | | | | | | | | This merges their code. They're backed by the same single HACL* static library, having them be a single module simplifies maintenance. This should unbreak the wasm enscripten builds that currently fail due to linking in --whole-archive mode and the HACL* library appearing twice. Long unnoticed error fixed: _sha512.SHA384Type was doubly assigned and was actually SHA512Type. Nobody depends on those internal names. Also rename LIBHACL_ make vars to LIBHACL_SHA2_ in preperation for other future HACL things.

* gh-99108: Replace SHA2-224 & 256 with verified code from HACL* (#99109)Jonathan Protzenko2023-02-072-1/+5
| | | | | | | | | | | | | | | | | | | | | | replacing hashlib primitives (for the non-OpenSSL case) with verified implementations from HACL*. This is the first PR in the series, and focuses specifically on SHA2-256 and SHA2-224. This PR imports Hacl_Streaming_SHA2 into the Python tree. This is the HACL* implementation of SHA2, which combines a core implementation of SHA2 along with a layer of buffer management that allows updating the digest with any number of bytes. This supersedes the previous implementation in the tree. @franziskuskiefer was kind enough to benchmark the changes: in addition to being verified (thus providing significant safety and security improvements), this implementation also provides a sizeable performance boost! ``` --------------------------------------------------------------- Benchmark Time CPU Iterations --------------------------------------------------------------- Sha2_256_Streaming 3163 ns 3160 ns 219353 // this PR LibTomCrypt_Sha2_256 5057 ns 5056 ns 136234 // library used by Python currently ``` The changes in this PR are as follows: - import the subset of HACL* that covers SHA2-256/224 into `Modules/_hacl` - rewire sha256module.c to use the HACL* implementation Co-authored-by: Gregory P.

* gh-101524: Split Up the _xxsubinterpreters Module (gh-101526)Eric Snow2023-02-042-0/+4

| | | | | | Windows (GH-101352) To use this, ensure that clang support was selected in Visual Studio Installer, then set the PlatformToolset environment variable to "ClangCL" and build as normal from the command line. It remains unsupported, but at least is possible now for experimentation.

* gh-47146: Soft-deprecate structmember.h, expose its contents via Python.h ↵Petr Viktorin2022-11-222-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-99014) The ``structmember.h`` header is deprecated, though it continues to be available and there are no plans to remove it. There are no deprecation warnings. Old code can stay unchanged (unless the extra include and non-namespaced macros bother you greatly). Specifically, no uses in CPython are updated -- that would just be unnecessary churn. The ``structmember.h`` header is deprecated, though it continues to be available and there are no plans to remove it. Its contents are now available just by including ``Python.h``, with a ``Py`` prefix added if it was missing: - `PyMemberDef`, `PyMember_GetOne` and`PyMember_SetOne` - Type macros like `Py_T_INT`, `Py_T_DOUBLE`, etc. (previously ``T_INT``, ``T_DOUBLE``, etc.) - The flags `Py_READONLY` (previously ``READONLY``) and `Py_AUDIT_READ` (previously all uppercase) Several items are not exposed from ``Python.h``: - `T_OBJECT` (use `Py_T_OBJECT_EX`) - `T_NONE` (previously undocumented, and pretty quirky) - The macro ``WRITE_RESTRICTED`` which does nothing. - The macros ``RESTRICTED`` and ``READ_RESTRICTED``, equivalents of `Py_AUDIT_READ`. - In some configurations, ``<stddef.h>`` is not included from ``Python.h``. It should be included manually when using ``offsetof()``. The deprecated header continues to provide its original contents under the original names. Your old code can stay unchanged, unless the extra include and non-namespaced macros bother you greatly. There is discussion on the issue to rename `T_PYSSIZET` to `PY_T_SSIZE` or similar. I chose not to do that -- users will probably copy/paste that with any spelling, and not renaming it makes migration docs simpler.

* gh-81057: Move the Allocators to _PyRuntimeState (gh-99217)Eric Snow2022-11-112-0/+12
| | | | | The global allocators were stored in 3 static global variables: _PyMem_Raw, _PyMem, and _PyObject. State for the "small block" allocator was stored in another 13. That makes a total of 16 global variables. We are moving all 16 to the _PyRuntimeState struct as part of the work for gh-81057. (If PEP 684 is accepted then we will follow up by moving them all to PyInterpreterState.) https://github.com/python/cpython/issues/81057

For projects still using distutils and cannot be updated to something else, the setuptools project can be installed: it still provides distutils. * Remove Lib/distutils/ directory * Remove test_distutils * Remove references to distutils * Skip test_check_c_globals and test_peg_generator since they use distutils
