* [3.12] gh-107471: Fix Refleaks in test_import (gh-107569) (#107571)Miss Islington (bot)2023-08-021-0/+1
| | | | | | | | | | | | gh-107471: Fix Refleaks in test_import (gh-107569) gh-107184 introduced a refleak in test_import.SubinterpImportTests (specifically test_singlephase_check_with_setting_and_override and test_single_init_extension_compat). We fix it here by making sure _testsinglephase is removed from sys.modules whenever we clear the runtime's internal state for the module. The underlying problem is strictly contained in the internal function _PyImport_ClearExtension() (AKA _testinternalcapi.clear_extension()), which is only used in tests. (This also fixes an intermittent segfault introduced in the same place, in test_disallowed_reimport.)

* [3.12] gh-105699: Use a _Py_hashtable_t for the PyModuleDef Cache ↵Eric Snow2023-07-282-171/+122
| | | | | | | | | | | | | (gh-106974) (gh-107412) gh-105699: Use a _Py_hashtable_t for the PyModuleDef Cache (gh-106974) This fixes a crasher due to a race condition, triggered infrequently when two isolated (own GIL) subinterpreters simultaneously initialize their sys or builtins modules. The crash happened due the combination of the "detached" thread state we were using and the "last holder" logic we use for the GIL. It turns out it's tricky to use the same thread state for different threads. Who could have guessed? We solve the problem by eliminating the one object we were still sharing between interpreters. We replace it with a low-level hashtable, using the "raw" allocator to avoid tying it to the main interpreter. We also remove the accommodations for "detached" thread states, which were a dubious idea to start with. (cherry picked from commit 8ba4df91ae60833723d8d3b9afeb2b642f7176d5)

| | | | | | | | (gh-105765) This fixes a race during import. The existing _PyRuntimeState.imports.pkgcontext is shared between interpreters, and occasionally this would cause a crash when multiple interpreters were importing extensions modules at the same time. To solve this we add a thread-local variable for the value. We also leave the existing state (and infrequent race) in place for platforms that do not support thread-local variables.
