* gh-116167: Allow disabling the GIL with `PYTHON_GIL=0` or `-X gil=0` (#116338)Brett Simmers2024-03-111-0/+4
| | | | | | | | | In free-threaded builds, running with `PYTHON_GIL=0` will now disable the GIL. Follow-up issues track work to re-enable the GIL when loading an incompatible extension, and to disable the GIL by default. In order to support re-enabling the GIL at runtime, all GIL-related data structures are initialized as usual, and disabling the GIL simply sets a flag that causes `take_gil()` and `drop_gil()` to return early.
* gh-73965: New environment variable PYTHON_HISTORY (#13208)Zackery Spytz2024-01-071-0/+3

* gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)Victor Stinner2022-05-051-1/+13
| | | | | | | | | | | | Add the -P command line option and the PYTHONSAFEPATH environment variable to not prepend a potentially unsafe path to sys.path. * Add sys.flags.safe_path flag. * Add PyConfig.safe_path member. * Programs/_bootstrap_python.c uses config.safe_path=0. * Update subprocess._optim_args_from_interpreter_flags() to handle the -P command line option. * Modules/getpath.py sets safe_path to 1 if a "._pth" file is present.
* bpo-44584: Deprecate PYTHONTHREADDEBUG env var (GH-27065)Victor Stinner2021-08-061-0/+1
| | | | | The threading debug (PYTHONTHREADDEBUG environment variable) is deprecated in Python 3.10 and will be removed in Python 3.12. This feature requires a debug build of Python.
* bpo-43862: Enhance -W cmdline option documentation (GH-25439)Victor Stinner2021-04-161-56/+61

* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

| | | | | | | | | | -I Run Python in isolated mode. This also implies -E and -s. In isolated mode sys.path contains neither the script’s directory nor the user’s site-packages directory. All PYTHON* environment variables are ignored, too. Further restrictions may be imposed to prevent the user from injecting malicious code.
