* GH-104584: Fix incorrect uoperands (GH-107513)Brandt Bucher2023-07-311-1/+2
|
* GH-104909: Move unused cache entries from uops to macros (#107444)Guido van Rossum2023-07-313-21/+7
| | | | | | There's no need to use a dummy uop to skip unused cache entries. The macro syntax lets you write `unused/1` instead. Similarly, move `unused/5` from op `_LOAD_ATTR_INSTANCE_VALUE` to macro `LOAD_ATTR_INSTANCE_VALUE`.
* no-issue: Fix typo in import.c (gh-107498)Georg Brandl2023-07-311-1/+1

* gh-105699: Use a _Py_hashtable_t for the PyModuleDef Cache (gh-106974)Eric Snow2023-07-282-171/+122
| | | | | | | 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.
* gh-101524: Only Use Public C-API in the _xxsubinterpreters Module (gh-107359)Eric Snow2023-07-271-1/+1
| | | The _xxsubinterpreters module should not rely on internal API. Some of the functions it uses were recently moved there however. Here we move them back (and expose them properly).
* gh-104621: Check for Incompatible Extensions in import_find_extension() ↵Eric Snow2023-07-271-10/+11
| | | | | (gh-107184) This fixes a bug where incompatible modules could still be imported if attempted multiple times.
* gh-106931: Intern Statically Allocated Strings Globally (gh-107272)Eric Snow2023-07-271-0/+7
| | | | | 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.

* gh-107211: Rename PySymtable_Lookup() to _PySymtable_Lookup() (#107212)Victor Stinner2023-07-252-3/+3
| | | | Rename the internal PySymtable_Lookup() function to _PySymtable_Lookup() and no longer export it.

* gh-106320: Remove private _PyDict C API (#107145)Victor Stinner2023-07-244-1/+5
| | | | | | | | | | | | | Move private _PyDict functions to the internal C API (pycore_dict.h): * _PyDict_Contains_KnownHash() * _PyDict_DebugMallocStats() * _PyDict_DelItemIf() * _PyDict_GetItemWithError() * _PyDict_HasOnlyStringKeys() * _PyDict_MaybeUntrack() * _PyDict_MergeEx() No longer export these functions.
* gh-106320: Remove private _PyObject C API (#107147)Victor Stinner2023-07-231-1/+1
| | | | | | | | | | | | | | | | Move private debug _PyObject functions to the internal C API (pycore_object.h): * _PyDebugAllocatorStats() * _PyObject_CheckConsistency() * _PyObject_DebugTypeStats() * _PyObject_IsFreed() No longer export most of these functions, except of _PyObject_IsFreed(). Move test functions using _PyObject_IsFreed() from _testcapi to _testinternalcapi. check_pyobject_is_freed() test no longer catch _testcapi.error: the tested function cannot raise _testcapi.error.
* GH-103082: Rename PY_MONITORING_EVENTS to _PY_MONITORING_EVENTS (#107069)Victor Stinner2023-07-223-24/+24

* gh-106603: Make uop struct a triple (opcode, oparg, operand) (#106794)Guido van Rossum2023-07-175-68/+145
|
* gh-106581: Add 10 new opcodes by allowing `assert(kwnames == NULL)` (#106707)Guido van Rossum2023-07-175-30/+365
| | | | | | | | | | | | | By turning `assert(kwnames == NULL)` into a macro that is not in the "forbidden" list, many instructions that formerly were skipped because they contained such an assert (but no other mention of `kwnames`) are now supported in Tier 2. This covers 10 instructions in total (all specializations of `CALL` that invoke some C code): - `CALL_NO_KW_TYPE_1` - `CALL_NO_KW_STR_1` - `CALL_NO_KW_TUPLE_1` - `CALL_NO_KW_BUILTIN_O` - `CALL_NO_KW_BUILTIN_FAST` - `CALL_NO_KW_LEN` - `CALL_NO_KW_ISINSTANCE` - `CALL_NO_KW_METHOD_DESCRIPTOR_O` - `CALL_NO_KW_METHOD_DESCRIPTOR_NOARGS` - `CALL_NO_KW_METHOD_DESCRIPTOR_FAST`
* gh-106529: Generate uops for POP_JUMP_IF_[NOT_]NONE (#106796)Guido van Rossum2023-07-171-0/+17
| | | | | | | | These aren't automatically translated because (ironically) they are macros deferring to POP_JUMP_IF_{TRUE,FALSE}, which are not viable uops (being manually translated). The hack is that we emit IS_NONE and then set opcode and jump to the POP_JUMP_IF_{TRUE,FALSE} translation code.

* gh-106529: Fix subtle Tier 2 edge case with list iterator (#106756)Guido van Rossum2023-07-152-4/+24
| | | | | | | | | | | | The Tier 2 opcode _IS_ITER_EXHAUSTED_LIST (and _TUPLE) didn't set it->it_seq to NULL, causing a subtle bug that resulted in test_exhausted_iterator in list_tests.py to fail when running all tests with -Xuops. The bug was introduced in gh-106696. Added this as an explicit test. Also fixed the dependencies for ceval.o -- it depends on executor_cases.c.h.
* gh-105481: expose opcode metadata via the _opcode module (#106688)Irit Katriel2023-07-142-3/+33

* gh-106529: Split FOR_ITER_{LIST,TUPLE} into uops (#106696)Guido van Rossum2023-07-144-102/+314
| | | | Also rename `_ITER_EXHAUSTED_XXX` to `_IS_ITER_EXHAUSTED_XXX` to make it clear this is a test.
* gh-106701: Move the hand-written Tier 2 uops to bytecodes.c (#106702)Guido van Rossum2023-07-133-40/+66
| | | | | | | This moves EXIT_TRACE, SAVE_IP, JUMP_TO_TOP, and _POP_JUMP_IF_{FALSE,TRUE} from ceval.c to bytecodes.c. They are no less special than before, but this way they are discoverable o the copy-and-patch tooling.
