- Generalize the syntax for the type of a stack effect to allow a trailing `*`,
so we can declare something as e.g. `PyCodeObject *`.
- When generating assignments for stack effects,
the type of the value on the stack should be the default (i.e., `PyObject *`)
even when the variable copied to/from it has a different type,
so that an appropriate cast is generated
However, not when the variable is an array --
then the type is taken from the variable (as it is always `PyObject **`).
This is a follow-up to gh-107567 and gh-107733.
We skip test_basic_multiple_interpreters_deleted_no_reset on tracerefs builds. The test breaks interpreter isolation a little, which doesn't work well with Py_TRACE_REFS builds, so I feel fine about skipping the test.
PEP 683 (immortal objects) revealed some ways in which the Python documentation has been unnecessarily coupled to the implementation details of reference counts. In the end users should focus on reference ownership, including taking references and releasing them, rather than on how many reference counts an object has.
This change updates the documentation to reflect that perspective. It also updates the docs relative to immortal objects in a handful of places.
Cover all the Mapping Protocol, almost all the Sequence Protocol
(except PySequence_Fast) and a part of the Object Protocol.
Move existing tests to Lib/test/test_capi/test_abstract.py and
Modules/_testcapi/abstract.c.
Add also tests for PyDict C API.
This patch escapes the class name before embedding it in the regular expression
for `pat` in `doctest.DocTestFinder._find_lineno`. While class names do not
ordinarily contain special characters, it is possible to encounter these when a
class is created dynamically. Escaping the name will correctly return `None` in
this scenario, rather than potentially matching a different class or raising
`re.error` depending on the symbols used.
It is now possible to deprecate passing parameters positionally with
Argument Clinic, using the new '* [from X.Y]' syntax.
(To be read as "keyword-only from Python version X.Y")

- Add links to `__main__` and `sys.path` where appropriate
- Ensure each paragraph never has more than one link to the same thing, to avoid visual clutter from too many links
gh-107432 Fix incorrect indentation in annotations document
Body text in https://docs.python.org/3/howto/annotations.html was
indented throughout, and was being rendered in blockquote elements.
This fixes two tiny defects in analysis.py that I didn't catch on time in #107564:
- `get_var_names` in `check_macro_consistency` should skip `UNUSED` names.
- Fix an occurrence of `is UNUSED` (should be `==`).
Introducing a new file, stacking.py, that takes over several responsibilities related to symbolic evaluation of push/pop operations, with more generality.
- always wrap the offending line, token, or name in quotes
- in most cases, put the entire error message on one line
Added tests for uncovered branches that were touched by this PR.
