* [3.13] gh-130940: Remove PyConfig.use_system_logger (#131129)Russell Keith-Magee2025-03-131-3/+0
| | | | | | | Removes ``PyConfig.use_system_logger``, resolving an ABI incompatibility introduced in 3.13.2. Changes the default behavior of iOS to *always* direct stdout/stderr to the system log.
* [3.13] gh-126925: Modify how iOS test results are gathered (GH-127592) (#127754)Russell Keith-Magee2024-12-091-0/+3
| | | | | | | | Adds a `use_system_log` config item to enable stdout/stderr redirection for Apple platforms. This log streaming is then used by a new iOS test runner script, allowing the display of test suite output at runtime. The iOS test runner script can be used by any Python project, not just the CPython test suite. (cherry picked from commit 2041a95e68ebf6d13f867e214ada28affa830669)
* gh-116167: Allow disabling the GIL with `PYTHON_GIL=0` or `-X gil=0` (#116338)Brett Simmers2024-03-111-0/+3
| | | | | | | | | 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-109853: Fix sys.path[0] For Subinterpreters (gh-109994)Eric Snow2023-10-021-0/+3
| | | This change makes sure sys.path[0] is set properly for subinterpreters. Before, it wasn't getting set at all. This PR does not address the broader concerns from gh-109853.
* gh-108753: Enhance pystats (#108754)Victor Stinner2023-09-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Statistics gathering is now off by default. Use the "-X pystats" command line option or set the new PYTHONSTATS environment variable to 1 to turn statistics gathering on at Python startup. Statistics are no longer dumped at exit if statistics gathering was off or statistics have been cleared. Changes: * Add PYTHONSTATS environment variable. * sys._stats_dump() now returns False if statistics are not dumped because they are all equal to zero. * Add PyConfig._pystats member. * Add tests on sys functions and on setting PyConfig._pystats to 1. * Add Include/cpython/pystats.h and Include/internal/pycore_pystats.h header files. * Rename '_py_stats' variable to '_Py_stats'. * Exclude Include/cpython/pystats.h from the Py_LIMITED_API. * Move pystats.h include from object.h to Python.h. * Add _Py_StatsOn() and _Py_StatsOff() functions. Remove '_py_stats_struct' variable from the API: make it static in specialize.c. * Document API in Include/pystats.h and Include/cpython/pystats.h. * Complete pystats documentation in Doc/using/configure.rst. * Don't write "all zeros" stats: if _stats_off() and _stats_clear() or _stats_dump() were called. * _PyEval_Fini() now always call _Py_PrintSpecializationStats() which does nothing if stats are all zeros.

* gh-106320: Remove private _PyErr_ChainExceptions() (#108713)Victor Stinner2023-08-311-1/+0
| | | | | | | | | | | | | Remove _PyErr_ChainExceptions(), _PyErr_ChainExceptions1() and _PyErr_SetFromPyStatus() functions from the public C API. * Move the private _PyErr_ChainExceptions() and _PyErr_ChainExceptions1() function to the internal C API (pycore_pyerrors.h). * Move the private _PyErr_SetFromPyStatus() to the internal C API (pycore_initconfig.h). * No longer export the _PyErr_ChainExceptions() function. * Move run_in_subinterp_with_config() from _testcapi to _testinternalcapi.
* gh-98608: Move PyInterpreterConfig to pylifecycle.h (#107191)Victor Stinner2023-07-241-39/+0
| | | | | Move PyInterpreterConfig structure and associated macros from initconfig.h to pylifecycle.h: it's not related to the Python Initialization Configuration.
* gh-105603: Change the PyInterpreterConfig.own gil Field (gh-105620)Eric Snow2023-06-131-3/+7
| | | We are changing it to be more flexible that a strict bool can be for possible future expanded used cases.
* gh-99113: Add PyInterpreterConfig.own_gil (gh-104204)Eric Snow2023-05-051-0/+3
| | | | | We also add PyInterpreterState.ceval.own_gil to record if the interpreter actually has its own GIL. Note that for now we don't actually respect own_gil; all interpreters still share the one GIL. However, PyInterpreterState.ceval.own_gil does reflect PyInterpreterConfig.own_gil. That lie is a temporary one that we will fix when the GIL really becomes per-interpreter.
* gh-104109: Expose Py_NewInterpreterFromConfig() in the Public C-API (gh-104110)Eric Snow2023-05-031-1/+1
| | | | | We also expose PyInterpreterConfig. This is part of the PEP 684 (per-interpreter GIL) implementation. We will add docs as soon as we can. FYI, I'm adding the new config field for per-interpreter GIL in gh-99114.
* gh-101659: Isolate "obmalloc" State to Each Interpreter (gh-101660)Eric Snow2023-04-241-0/+4
| | | | | | | | | | | | | | This is strictly about moving the "obmalloc" runtime state from `_PyRuntimeState` to `PyInterpreterState`. Doing so improves isolation between interpreters, specifically most of the memory (incl. objects) allocated for each interpreter's use. This is important for a per-interpreter GIL, but such isolation is valuable even without it. FWIW, a per-interpreter obmalloc is the proverbial canary-in-the-coalmine when it comes to the isolation of objects between interpreters. Any object that leaks (unintentionally) to another interpreter is highly likely to cause a crash (on debug builds at least). That's a useful thing to know, relative to interpreter isolation.
* gh-98608: Stop Treating All Errors from _Py_NewInterpreterFromConfig() as ↵Eric Snow2023-03-211-0/+1
| | | | | | | Fatal (gh-102657) Prior to this change, errors in _Py_NewInterpreterFromConfig() were always fatal. Instead, callers should be able to handle such errors and keep going. That's what this change supports. (This was an oversight in the original implementation of _Py_NewInterpreterFromConfig().) Note that the existing [fatal] behavior of the public Py_NewInterpreter() is preserved. https://github.com/python/cpython/issues/98608
* gh-98627: Add an Optional Check for Extension Module Subinterpreter ↵Eric Snow2023-02-161-0/+3
| | | | | | | | | | | | | | | Compatibility (gh-99040) Enforcing (optionally) the restriction set by PEP 489 makes sense. Furthermore, this sets the stage for a potential restriction related to a per-interpreter GIL. This change includes the following: * add tests for extension module subinterpreter compatibility * add _PyInterpreterConfig.check_multi_interp_extensions * add Py_RTFLAGS_MULTI_INTERP_EXTENSIONS * add _PyImport_CheckSubinterpIncompatibleExtensionAllowed() * fail iff the module does not implement multi-phase init and the current interpreter is configured to check https://github.com/python/cpython/issues/98627
* gh-98610: Adjust the Optional Restrictions on Subinterpreters (GH-98618)Eric Snow2022-10-311-2/+12
| | | | | | | Previously, the optional restrictions on subinterpreters were: disallow fork, subprocess, and threads. By default, we were disallowing all three for "isolated" interpreters. We always allowed all three for the main interpreter and those created through the legacy `Py_NewInterpreter()` API. Those settings were a bit conservative, so here we've adjusted the optional restrictions to: fork, exec, threads, and daemon threads. The default for "isolated" interpreters disables fork, exec, and daemon threads. Regular threads are allowed by default. We continue always allowing everything For the main interpreter and the legacy API. In the code, we add `_PyInterpreterConfig.allow_exec` and `_PyInterpreterConfig.allow_daemon_threads`. We also add `Py_RTFLAGS_DAEMON_THREADS` and `Py_RTFLAGS_EXEC`.
* gh-98608: Change _Py_NewInterpreter() to _Py_NewInterpreterFromConfig() ↵Eric Snow2022-10-261-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | (gh-98609) (see https://github.com/python/cpython/issues/98608) This change does the following: 1. change the argument to a new `_PyInterpreterConfig` struct 2. rename the function to `_Py_NewInterpreterFromConfig()`, inspired by `Py_InitializeFromConfig()` (takes a `_PyInterpreterConfig` instead of `isolated_subinterpreter`) 3. split up the boolean `isolated_subinterpreter` into the corresponding multiple granular settings * allow_fork * allow_subprocess * allow_threads 4. add `PyInterpreterState.feature_flags` to store those settings 5. add a function for checking if a feature is enabled on an opaque `PyInterpreterState *` 6. drop `PyConfig._isolated_interpreter` The existing default (see `Py_NewInterpeter()` and `Py_Initialize*()`) allows fork, subprocess, and threads and the optional "isolated" interpreter (see the `_xxsubinterpreters` module) disables all three. None of that changes here; the defaults are preserved. Note that the given `_PyInterpreterConfig` will not be used outside `_Py_NewInterpreterFromConfig()`, nor preserved. This contrasts with how `PyConfig` is currently preserved, used, and even modified outside `Py_InitializeFromConfig()`. I'd rather just avoid that mess from the start for `_PyInterpreterConfig`. We can preserve it later if we find an actual need. This change allows us to follow up with a number of improvements (e.g. stop disallowing subprocess and support disallowing exec instead). (Note that this PR adds "private" symbols. We'll probably make them public, and add docs, in a separate change.)
* gh-96512: Move int_max_str_digits setting to PyConfig (#96944)Gregory P. Smith2022-10-031-0/+1
| | | | | | | | | | | It had to live as a global outside of PyConfig for stable ABI reasons in the pre-3.12 backports. This removes the `_Py_global_config_int_max_str_digits` and gets rid of the equivalent field in the internal `struct _is PyInterpreterState` as code can just use the existing nested config struct within that. Adds tests to verify unique settings and configs in subinterpreters.

* gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)Victor Stinner2022-05-051-0/+1
| | | | | | | | | | | | 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-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-0/+3
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.

| | | | | | | frozen modules. (gh-28320) Currently we freeze several modules into the runtime. For each of these modules it is essential to bootstrapping the runtime that they be frozen. Any other stdlib module that we later freeze into the runtime is not essential. We can just as well import from the .py file. This PR lets users explicitly choose which should be used, with the new "-X frozen_modules=[on|off]" CLI flag. The default is "off" for now. https://bugs.python.org/issue45020

| | | | | | | | | | | | | | | | | | | | | Enhance the documentation of the Python startup, filesystem encoding and error handling, locale encoding. Add a new "Python UTF-8 Mode" section. * Add "locale encoding" and "filesystem encoding and error handler" to the glossary * Remove documentation from Include/cpython/initconfig.h: move it to Doc/c-api/init_config.rst. * Doc/c-api/init_config.rst: * Document command line options and environment variables * Document default values. * Add a new "Python UTF-8 Mode" section in Doc/library/os.rst. * Add warnings to Py_DecodeLocale() and Py_EncodeLocale() docs. * Document how Python selects the filesystem encoding and error handler at a single place: PyConfig.filesystem_encoding and PyConfig.filesystem_errors. * PyConfig: move orig_argv member at the right place.
* bpo-42236: Use UTF-8 encoding if nl_langinfo(CODESET) fails (GH-23086)Victor Stinner2020-11-011-30/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the nl_langinfo(CODESET) function returns an empty string, Python now uses UTF-8 as the filesystem encoding. In May 2010 (commit b744ba1d14c5487576c95d0311e357b707600b47), I modified Python to log a warning and use UTF-8 as the filesystem encoding (instead of None) if nl_langinfo(CODESET) returns an empty string. In August 2020 (commit 94908bbc1503df830d1d615e7b57744ae1b41079), I modified Python startup to fail with a fatal error and a specific error message if nl_langinfo(CODESET) returns an empty string. The intent was to prevent guessing the encoding and also investigate user configuration where this case happens. In 10 years (2010 to 2020), I saw zero user report about the error message related to nl_langinfo(CODESET) returning an empty string. Today, UTF-8 became the defacto standard and it's safe to make the assumption that the user expects UTF-8. For example, nl_langinfo(CODESET) can return an empty string on macOS if the LC_CTYPE locale is not supported, and UTF-8 is the default encoding on macOS. While this change is likely to not affect anyone in practice, it should make UTF-8 lover happy ;-) Rewrite also the documentation explaining how Python selects the filesystem encoding and error handler.
