| | | | | | | | | | | | | | | | | gh-113343: Fix error check on mmap(2) (GH-113342) Fix error check on mmap(2) It should check MAP_FAILED instead of NULL for error. On mmap(2) man page: RETURN VALUE On success, mmap() returns a pointer to the mapped area. On error, the value MAP_FAILED (that is, (void *) -1) is returned, and errno is set to indicate the error.

* [3.12] gh-110310: Add a Per-Interpreter XID Registry for Heap Types ↵Eric Snow2023-11-281-38/+120
| | | | | | | | | | | | | | | (gh-110311) (gh-110714) We do the following: * add a per-interpreter XID registry (PyInterpreterState.xidregistry) * put heap types there (keep static types in _PyRuntimeState.xidregistry) * clear the registries during interpreter/runtime finalization * avoid duplicate entries in the registry (when _PyCrossInterpreterData_RegisterClass() is called more than once for a type) * use Py_TYPE() instead of PyObject_Type() in _PyCrossInterpreterData_Lookup() The per-interpreter registry helps preserve isolation between interpreters. This is important when heap types are registered, which is something we haven't been doing yet but I will likely do soon. (cherry-picked from commit 80dc39e1dc2abc809f448cba5d2c5b9c1c631e11)
* [3.12] gh-105716: Support Background Threads in Subinterpreters Consistently ↵Eric Snow2023-11-281-0/+37
| | | | | | | | | (gh-109921) (gh-110707) The existence of background threads running on a subinterpreter was preventing interpreters from getting properly destroyed, as well as impacting the ability to run the interpreter again. It also affected how we wait for non-daemon threads to finish. We add PyInterpreterState.threads.main, with some internal C-API functions. (cherry-picked from commit 1dd9dee45d2591b4e701039d1673282380696849)
* [3.12] gh-109793: Allow Switching Interpreters During Finalization ↵Eric Snow2023-11-281-1/+16
| | | | | (gh-109794) (gh-110705) Essentially, we should check the thread ID rather than the thread state pointer.
* [3.12] gh-106931: Intern Statically Allocated Strings Globally (gh-107272) ↵Eric Snow2023-11-271-0/+7
| | | | | | | | | (gh-110713) We tried this before with a dict and for all interned strings. That ran into problems due to interpreter isolation. However, exclusively using a per-interpreter cache caused some inconsistency that can eliminate the benefit of interning. Here we circle back to using a global cache, but only for statically allocated strings. We also use a more-basic _Py_hashtable_t for that global cache instead of a dict. Ideally we would only have the global cache, but the optional isolation of each interpreter's allocator means that a non-static string object must not outlive its interpreter. Thus we would have to store a copy of each such interned string in the global cache, tied to the main interpreter. (cherry-picked from commit b72947a8d26915156323ccfd04d273199ecb870c)

| | | | | | | | | | | | | | | | | | | | | | | | | | | (#110342) * gh-108987: Fix _thread.start_new_thread() race condition (#109135) Fix _thread.start_new_thread() race condition. If a thread is created during Python finalization, the newly spawned thread now exits immediately instead of trying to access freed memory and lead to a crash. thread_run() calls PyEval_AcquireThread() which checks if the thread must exit. The problem was that tstate was dereferenced earlier in _PyThreadState_Bind() which leads to a crash most of the time. Move _PyThreadState_CheckConsistency() from thread_run() to _PyThreadState_Bind().
