* gh-84436: Implement Immortal Objects (gh-19474)Eddie Elizondo2023-04-221-1/+1
| | | | | | | | | This is the implementation of PEP683 Motivation: The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime. Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.

* GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython ↵Mark Shannon2023-04-122-5/+3
| | | | | | | | | | (GH-103083) * The majority of the monitoring code is in instrumentation.c * The new instrumentation bytecodes are in bytecodes.c * legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs
* gh-91276: remove unused _PyOpcode_RelativeJump (#103156)Irit Katriel2023-04-111-2/+0

* gh-87092: move CFG related code from compile.c to flowgraph.c (#103021)Irit Katriel2023-03-311-1/+3

* gh-100227: Move the Dict of Interned Strings to PyInterpreterState (gh-102339)Eric Snow2023-03-281-2/+2
| | | | | We can revisit the options for keeping it global later, if desired. For now the approach seems quite complex, so we've gone with the simpler isolation solution in the meantime. https://github.com/python/cpython/issues/100227
* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-4/+6
| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().
* GH-94851: check unicode consistency of static strings in debug mode (#102684)Kumar Aditya2023-03-141-0/+1
|
* gh-101524: Split Up the _xxsubinterpreters Module (gh-101526)Eric Snow2023-02-041-0/+1
| | | | | This is step 1 in potentially dropping all the "channel"-related code. Channels have already been removed from PEP 554. https://github.com/python/cpython/issues/101524
* Add advice how to freeze fewer modules (#101298)Guido van Rossum2023-01-251-1/+6
| | | (And fix a bug that only occurs when you follow the advice.)
* gh-100712: make it possible to disable specialization (for debugging) (#100713)Irit Katriel2023-01-191-0/+5
|
* GH-100719: Remove the `co_nplaincellvars` field from code objects. (GH-100721)Mark Shannon2023-01-041-6/+2

* gh-100720: refactor calculation of number of frame slots for a code object ↵Irit Katriel2023-01-041-0/+1
| | | | into the new function _PyFrame_NumSlotsForCodeObject (#100722)
* GH-98522: Add version number to code objects. (GH-98525)Mark Shannon2022-12-091-0/+5
| | | | | | * Add version number to code object for better versioning of functions. * Improves specialization for closures and list comprehensions.
* gh-96002: Add functional test for Argument Clinic (#96178)colorfulappl2022-11-211-0/+1

* gh-81057: Move contextvars-related Globals to _PyRuntimeState (gh-99400)Eric Snow2022-11-161-0/+3
| | | | | This is part of the effort to consolidate global variables, to make them easier to manage (and make it easier to later move some of them to PyInterpreterState). https://github.com/python/cpython/issues/81057
* gh-81057: Add PyInterpreterState.static_objects (gh-99397)Eric Snow2022-11-111-2/+4
| | | | | As we consolidate global variables, we find some objects that are almost suitable to add to _PyRuntimeState.global_objects, but have some small/sneaky bit of per-interpreter state (e.g. a weakref list). We're adding PyInterpreterState.static_objects so we can move such objects there. (We'll removed the _not_used field once we've added others.) https://github.com/python/cpython/issues/81057
* gh-81057: Generate a Separate Initializer For Each Part of the Global ↵Eric Snow2022-11-111-48/+49
| | | | | | | Objects Initializer (gh-99389) Up until now we had a single generated initializer macro for all the statically declared global objects in _PyRuntimeState, including several one-offs (e.g. the empty tuple). The one-offs don't need to be generated, but were because we had one big initializer. Having separate initializers for set of generated global objects allows us to generate only the ones we need to. This allows us to add initializers for one-off global objects without having to generate them. https://github.com/python/cpython/issues/81057
* gh-90868: Add _PyStaticObject_CheckRefcnt() function (#99261)Victor Stinner2022-11-091-5/+2
| | | | | | Add _PyStaticObject_CheckRefcnt() function to make _PyStaticObjects_CheckRefcnt() shorter. Use _PyObject_ASSERT_FAILED_MSG() to log the object causing the fatal error.
* gh-90868: Adjust the Generated Objects (gh-99223)Eric Snow2022-11-081-3/+49
| | | | | | | | | | | We do the following: * move the generated _PyUnicode_InitStaticStrings() to its own file * move the generated _PyStaticObjects_CheckRefcnt() to its own file * include pycore_global_objects.h in extension modules instead of pycore_runtime_init.h These changes help us avoid including things that aren't needed. https://github.com/python/cpython/issues/90868
* gh-98627: Add the _testsinglephase Module (gh-99039)Eric Snow2022-11-081-0/+1
| | | | | This makes it more clear that a given test is definitely testing against a single-phase init (legacy) extension module. The new module is a companion to _testmultiphase. https://github.com/python/cpython/issues/98627
* gh-92584: Remove the distutils package (#99061)Victor Stinner2022-11-031-1/+0
| | | | | | | | | | | | Remove the distutils package. It was deprecated in Python 3.10 by PEP 632 "Deprecate distutils module". For projects still using distutils and cannot be updated to something else, the setuptools project can be installed: it still provides distutils. * Remove Lib/distutils/ directory * Remove test_distutils * Remove references to distutils * Skip test_check_c_globals and test_peg_generator since they use distutils
* gh-99016: Make build scripts compatible with Python 3.8 (GH-99017)Serhiy Storchaka2022-11-022-3/+3
|
* GH-98686: Quicken everything (GH-98687)Brandt Bucher2022-11-021-18/+11
|
* gh-97669: Create Tools/build/ directory (#97963)Victor Stinner2022-10-1716-0/+4529
Create Tools/build/ directory. Move the following scripts from Tools/scripts/ to Tools/build/: * check_extension_modules.py * deepfreeze.py * freeze_modules.py * generate_global_objects.py * generate_levenshtein_examples.py * generate_opcode_h.py * generate_re_casefix.py * generate_sre_constants.py * generate_stdlib_module_names.py * generate_token.py * parse_html5_entities.py * smelly.py * stable_abi.py * umarshal.py * update_file.py * verify_ensurepip_wheels.py Update references to these scripts.
