* bpo-46712: Share global string identifiers in deepfreeze (GH-31261)Kumar Aditya2022-02-252-6/+13
| | | Where appropriate, deepfreeze.c now uses `&_Py_ID(blah)` references instead of locally defining constants. This saves some space.

* bpo-46748: Don't import <stdbool.h> in public headers (GH-31553)Petr Viktorin2022-02-251-2/+2
| | | | | | | <stdbool.h> is the standard/modern way to define embedd/extends Python free to define bool, true and false, but there are existing applications that use slightly different redefinitions, which fail if the header is included. It's OK to use stdbool outside the public headers, though. https://bugs.python.org/issue46748

* bpo-46541: Discover the global strings. (gh-31346)Eric Snow2022-02-151-255/+74
| | | | | | | Instead of manually enumerating the global strings in generate_global_objects.py, we extrapolate the list from usage of _Py_ID() and _Py_STR() in the source files. This is partly inspired by gh-31261. https://bugs.python.org/issue46541

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-082-11/+486
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) 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

* bpo-46608: exclude marshalled-frozen data if deep-freezing to save 300 KB ↵Kumar Aditya2022-02-042-22/+28
| | | | | | | | | | | | | space (GH-31074) This reduces the size of the data segment by **300 KB** of the executable because if the modules are deep-frozen then the marshalled frozen data just wastes space. This was inspired by comment by @gvanrossum in https://github.com/python/cpython/pull/29118#issuecomment-958521863. Note: There is a new option `--deepfreeze-only` in `freeze_modules.py` to change this behavior, it is on be default to save disk space. ```console # du -s ./python before 27892 ./python # du -s ./python after 27524 ./python ``` Automerge-Triggered-By: GH:ericsnowcurrently

* bpo-46576: bpo-46524: Disable compiler optimization within ↵Gregory P. Smith2022-02-021-0/+10
| | | | | | | | | | | | | | | | | | | | test_peg_generator. (#31015) Disable compiler optimization within test_peg_generator. This speed up test_peg_generator by always disabling compiler optimizations by using -O0 or equivalent when the test is building its own C extensions. A build not using --with-pydebug in order to speed up test execution winds up with this test taking a very long time as it would do repeated compilation of parser C code using the same optimization flags as CPython was built with. This speeds the test up 6-8x on gps-raspbian. Also incorporate's #31017's win32 conditional and flags. Co-authored-by: Kumar Aditya kumaraditya303
