We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules.
The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings).
https://bugs.python.org/issue46541#msg411799 explains the rationale for this change.
The core of the change is in:
* (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros
* Include/internal/pycore_runtime_init.h - added the static initializers for the global strings
* Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState
* Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers
I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config.
The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *.
The following are not changed (yet):
* stop using _Py_IDENTIFIER() in the stdlib modules
* (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API
* (maybe) intern the strings during runtime init
https://bugs.python.org/issue46541
Prepare for module state:
- Add "get state by defining class" and "get state by module def" stubs
- Add AC defining class when needed
- Add state pointer to connection context
- Pass state as argument to utility functions
Automerge-Triggered-By: GH:encukou
With this, all sqlite3 static globals have been moved to the global state.
There are a couple of global static strings left, but there should be no need for adding them to the state.
https://bugs.python.org/issue42064
* Move connection type to global state
* Move cursor type to global state
* Move prepare protocol type to global state
* Move row type to global state
* Move statement type to global state
* ADD_TYPE takes a pointer
* pysqlite_get_state is now static inline

Fixes issue #3103. In the sqlite3 module, made one more function static. All renaming public symbos now have the pysqlite prefix to avoid name clashes. This at least once created problems where the same symbol name appeared somewhere in Apache and the sqlite3 module was used from mod_python.

Merged changes from standalone version 2.3.3. This should probably all be
merged into the 2.5 maintenance branch:
- self->statement was not checked while fetching data, which could
lead to crashes if you used the pysqlite API in unusual ways.
Closing the cursor and continuing to fetch data was enough.
- Converters are stored in a converters dictionary. The converter name
is uppercased first. The old upper-casing algorithm was wrong and
was replaced by a simple call to the Python string's upper() method
instead.
-Applied patch by Glyph Lefkowitz that fixes the problem with
subsequent SQLITE_SCHEMA errors.
- Improvement to the row type: rows can now be iterated over and have a keys()
method. This improves compatibility with both tuple and dict a lot.
- A bugfix for the subsecond resolution in timestamps.
- Corrected the way the flags PARSE_DECLTYPES and PARSE_COLNAMES are
checked for. Now they work as documented.
- gcc on Linux sucks. It exports all symbols by default in shared
libraries, so if symbols are not unique it can lead to problems with
symbol lookup. pysqlite used to crash under Apache when mod_cache
was enabled because both modules had the symbol cache_init. I fixed
this by applying the prefix pysqlite_ almost everywhere. Sigh.

number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html
Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:
test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec
This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.
