GH-101520: Move tracemalloc functionality into core, leaving interface in Modules. (#104508)

gh-103763: Implement PEP 695 (#103764)

2023-05-16T03:36:23+00:00

This implements PEP 695, Type Parameter Syntax. It adds support for:

- Generic functions (def func[T](): ...)
- Generic classes (class X[T](): ...)
- Type aliases (type X = ...)
- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules

gh-99108: Replace SHA3 implementation HACL* version (#103597)

2023-05-08T03:50:04+00:00

Replaces our built-in SHA3 implementation with a verified one from the HACL* project.

This implementation is used when OpenSSL does not provide SHA3 or is not present.

3.11 shiped with a very slow tiny sha3 implementation to get off of the <=3.10 reference implementation that wound up having serious bugs. This brings us back to a reasonably performing built-in implementation consistent with what we've just replaced our other guaranteed available standard hash algorithms with: code from the HACL* project.

GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython (GH-103083)

2023-04-12T11:04:55+00:00

* 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-87092: move assembler related code from compile.c to assemble.c (#103277)

gh-101659: Add _Py_AtExit() (gh-103298)

2023-04-06T00:42:02+00:00

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-102304: Move _Py_RefTotal to _PyRuntimeState (gh-102543)

2023-03-20T16:03:04+00:00

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.

gh-99726: Improves correctness of stat results for Windows, and uses faster API when available (GH-102149)

2023-03-16T17:27:21+00:00

This deprecates `st_ctime` fields on Windows, with the intent to change them to contain the correct value in 3.14. For now, they should keep returning the creation time as they always have.

gh-99108: Import MD5 and SHA1 from HACL* (#102089)

2023-02-22T21:18:43+00:00

Replaces our fallback non-OpenSSL MD5 and SHA1 implementations with those from HACL* as we've already done with SHA2.
