* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-0/+1
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).
* gh-71052: Fix several Android build issues (#115955)Malcolm Smith2024-02-291-1/+1
| | | | | | | | | | | | | | | | | | | This change is part of the work on PEP-738: Adding Android as a supported platform. * Remove the "1.0" suffix from libpython's filename on Android, which would prevent Gradle from packaging it into an app. * Simplify the build command in the Makefile so that libpython always gets given an SONAME with the `-Wl-h` argument, even if the SONAME is identical to the actual filename. * Disable a number of functions on Android which can be compiled and linked against, but always fail at runtime. As a result, the native _multiprocessing module is no longer built for Android. * gh-115390 (bee7bb331) added some pre-determined results to the configure script for things that can't be autodetected when cross-compiling; this change adds Android to these where appropriate. * Add a couple more pre-determined results for Android, and making them cover iOS as well. This means the --enable-ipv6 configure option will no longer be required on either platform.

* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
