Explicitly note that transactions are only closed if there is an open
transation at `__exit__`, and that transactions are not implicitly
opened during `__enter__`.

Move the follow functions and type from frameobject.h to pyframe.h,
so the standard <Python.h> provide frame getter functions:
* PyFrame_Check()
* PyFrame_GetBack()
* PyFrame_GetBuiltins()
* PyFrame_GetGenerator()
* PyFrame_GetGlobals()
* PyFrame_GetLasti()
* PyFrame_GetLocals()
* PyFrame_Type
Remove #include "frameobject.h" from many C files. It's no longer
needed.
- gh-93957: Provide nicer error reporting from subprocesses in test_venv.EnsurePipTest.test_with_pip.
- Update changelog
This change does three things:
1. Extract a function for trapping output in subprocesses.
2. Emit both stdout and stderr when encountering an error.
3. Apply the change to `ensurepip._uninstall` check.
Deprecate global configuration variable like
Py_IgnoreEnvironmentFlag: the Py_InitializeFromConfig() API should be
instead.
Fix declaration of Py_GETENV(): use PyAPI_FUNC(), not PyAPI_DATA().
test_asyncio, test_logging, test_socket and test_socketserver now
create AF_UNIX domains in the current directory to no longer fail
with OSError("AF_UNIX path too long") if the temporary directory (the
TMPDIR environment variable) is too long.
Modify the following tests to use create_unix_domain_name():
* test_asyncio
* test_logging
* test_socket
* test_socketserver
test_asyncio.utils: remove unused time import.
Revert "bpo-23689: re module, fix memory leak when a match is terminated by a signal or memory allocation failure (GH-32283)"
This reverts commit 6e3eee5c11.
Manual fixups to increase the MAGIC number and to handle conflicts with
a couple of changes that landed after that.
Thanks for reviews by Ma Lin and Serhiy Storchaka.
regrtest now also implements checking for leaked temporary files and
directories when using -jN for N >= 2. Use tempfile.mkdtemp() to
create the temporary directory. Skip this check on WASI.
SharedMemory.unlink() uses the unregister() function from resource_tracker. Previously it was imported in the method, but this can fail if the method is called during interpreter shutdown, for example when unlink is part of a __del__() method.
Moving the import to the top of the file, means that the unregister() method is available during interpreter shutdown.
The register call in SharedMemory.__init__() can also use this imported resource_tracker.
GH-26658 introduced a regression in copy / pickle protocol for combined
`enum.Flag`s. `copy.copy(re.A | re.I)` would fail with
`AttributeError: ASCII|IGNORECASE`.
`enum.Flag` now has a `__reduce_ex__()` method that reduces flags by
combined value, not by combined name.
Align the docs for the following methods with the actual implementation:
- sqlite3.complete_statement()
- sqlite3.Connection.create_function()
- sqlite3.Connection.create_aggregate()
- sqlite3.Connection.set_progress_handler()
The fix involves using pysqlite_check_remaining_sql(), not only to check
for multiple statements, but now also to strip leading comments and
whitespace from SQL statements, so we can improve DML query detection.
pysqlite_check_remaining_sql() is renamed lstrip_sql(), to more
accurately reflect its function, and hardened to handle more SQL comment
corner cases.
When changing PyType_FromMetaclass recently (GH-93012, GH-93466, GH-28748)
I found a bunch of opportunities to improve the code. Here they are.

Suppress writing an XML declaration in open files in ElementTree.write()
with encoding='unicode' and xml_declaration=None.
If file patch is passed to ElementTree.write() with encoding='unicode',
always open a new file in UTF-8.
Classes ReferenceType, ProxyType and CallableProxyType have now correct
atrtributes __module__, __name__ and __qualname__.
It makes them (types, not instances) pickleable.
Fix the importlib.resources.as_file() context manager to remove the
temporary file if destroyed late during Python finalization: keep a
local reference to the os.remove() function. Patch by Victor Stinner.
Documentation for `pathlib` says:
> Spurious slashes and single dots are collapsed, but double dots ('..') are not, since this would change the meaning of a path in the face of symbolic links:
However, it omits that initial double slashes also aren't collapsed.
Later, in documentation of `PurePath.drive`, `PurePath.root`, and `PurePath.name` it mentions UNC but:
- this abbreviation says nothing to a person who is unaware about existence of UNC (Wikipedia doesn't help either by [giving a disambiguation page](https://en.wikipedia.org/wiki/UNC))
- it shows up only if a person needs to use a specific property or decides to fully learn what the module provides.
For context, see the BPO entry.
This checks the bases of of a type created using the FromSpec
API to inherit the bases metaclasses. The metaclass's alloc
function will be called as is done in `tp_new` for classes
created in Python.

copy.copy() and copy.deepcopy() now always raise a TypeError if
__reduce__() returns a tuple with length 6 instead of silently ignore
the 6th item or produce incorrect result.
