- Establish global state struct
- Convert static types to heap types and add them to global state:
* PyDecContextManager_Type
* PyDecContext_Type
* PyDecSignalDictMixin_Type
* PyDec_Type
- Add to global state:
* PyDecSignalDict_Type
* DecimalTuple

This produces longer traces (superblocks?).
Also improved debug output (uop names are now printed instead of numeric opcodes). This would be simpler if the numeric opcode values were generated by generate_cases.py, but that's another project.
Refactored some code in generate_cases.py so the essential algorithm for cache effects is only run once. (Deciding which effects are used and what the total cache size is, regardless of what's used.)
Added a new, experimental, tracing optimizer and interpreter (a.k.a. "tier 2"). This currently pessimizes, so don't use yet -- this is infrastructure so we can experiment with optimizing passes. To enable it, pass ``-Xuops`` or set ``PYTHONUOPS=1``. To get debug output, set ``PYTHONUOPSDEBUG=N`` where ``N`` is a debug level (0-4, where 0 is no debug output and 4 is excessively verbose).
All of this code is likely to change dramatically before the 3.13 feature freeze. But this is a first step.
* Add table describing possible executable classes for out-of-process debuggers.
* Remove shim code object creation code as it is no longer needed.
* Make lltrace a bit more robust w.r.t. non-standard frames.
Remove compatibility code for Python 2 and early Python 3 versions.
* Remove os_fsencode() reimplementation: use os.fsencode() directly.
os.fsencode() was added to Python 3.2.
* Remove references to Python 2 and "Python 3": just say "Python".
* Remove outdated u'' string format: use '' instead.
This fixes a race during import. The existing _PyRuntimeState.imports.pkgcontext is shared between interpreters, and occasionally this would cause a crash when multiple interpreters were importing extensions modules at the same time. To solve this we add a thread-local variable for the value. We also leave the existing state (and infrequent race) in place for platforms that do not support thread-local variables.
For a while now, pending calls only run in the main thread (in the main interpreter). This PR changes things to allow any thread run a pending call, unless the pending call was explicitly added for the main thread to run.
The _xxsubinterpreters module was meant to only use public API. Some internal C-API usage snuck in over the last few years (e.g. gh-28969). This fixes that.
When I added the relevant condition to type_ready_set_bases() in gh-103912, I had missed that the function also sets tp_base and ob_type (if necessary). That led to problems for third-party static types.
We fix that here, by making those extra operations distinct and by adjusting the condition to be more specific.
Upgrade builds to OpenSSL 1.1.1u.
This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t.
The Mac/BuildScript/build-installer.py was already updated.
Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9, and adds a new _ssl_data_31.h file from 3.1.1 along with the ssl.c code to use it.
Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting).
backports of this prior to 3.12 will not include the openssl 3.1 header.
* refcounts.dat:
* Remove Py_UNICODE functions.
* Replace Py_UNICODE argument type with wchar_t.
* _PyUnicode_ToLowercase(), _PyUnicode_ToUppercase(),
_PyUnicode_ToTitlecase() are no longer deprecated in comments.
It's no longer needed since they now use Py_UCS4 type, rather than
the deprecated Py_UNICODE type.
* gdb: Remove unused char_width() method.
