* bpo-43950: Add code.co_positions (PEP 657) (GH-26955)Pablo Galindo2021-07-022-4/+23
| | | | | | | | | | | | | | | This PR is part of PEP 657 and augments the compiler to emit ending line numbers as well as starting and ending columns from the AST into compiled code objects. This allows bytecodes to be correlated to the exact source code ranges that generated them. This information is made available through the following public APIs: * The `co_positions` method on code objects. * The C API function `PyCode_Addr2Location`.

* bpo-44531: Add _PyType_AllocNoTrack() function (GH-26947)Victor Stinner2021-07-011-0/+2
| | | | | | | | | | | | Add an internal _PyType_AllocNoTrack() function to allocate an object without tracking it in the GC. Modify dict_new() to use _PyType_AllocNoTrack(): dict subclasses are now only tracked once all PyDictObject members are initialized. Calling _PyObject_GC_UNTRACK() is no longer needed for the dict type. Similar change in tuple_subtype_new() for tuple subclasses. Replace tuple_gc_track() with _PyObject_GC_TRACK().

* bpo-43693 Get rid of CO_NOFREE -- it's unused (GH-26839)Guido van Rossum2021-06-231-6/+0
| | | | | | All uses of this flag are either setting it or in doc or tests for it. So we should be able to get rid of it completely.
* bpo-39947: Remove old private trashcan C API functions (GH-26869)Victor Stinner2021-06-231-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove 4 C API private trashcan functions which were only kept for the backward compatibility of the stable ABI with Python 3.8 and older, since the trashcan API was not usable with the limited C API on Python 3.8 and older. The trashcan API was excluded from the limited C API in Python 3.9. Removed functions: * _PyTrash_deposit_object() * _PyTrash_destroy_chain() * _PyTrash_thread_deposit_object() * _PyTrash_thread_destroy_chain() The trashcan C API was never usable with the limited C API, since old trashcan macros accessed directly PyThreadState members like "_tstate->trash_delete_nesting", whereas the PyThreadState structure is opaque in the limited C API. Exclude also the PyTrash_UNWIND_LEVEL constant from the C API. The trashcan C API was modified in Python 3.9 by commit 38965ec5411da60d312b59be281f3510d58e0cf1 and in Python 3.10 by commit ed1a5a5baca8f61e9a99c5be3adc16b1801514fe to hide implementation details.

* bpo-43693: Turn localspluskinds into an object (GH-26749)Guido van Rossum2021-06-212-27/+18
| | | Managing it as a bare pointer to malloc'ed bytes is just too awkward in a few places.
* bpo-44337: Improve LOAD_ATTR specialization (GH-26759)Mark Shannon2021-06-211-0/+1
| | | | | | | | * Specialize obj.__class__ with LOAD_ATTR_SLOT * Specialize instance attribute lookup with attribute on class, provided attribute on class is not an overriding descriptor. * Add stat for how many times the unquickened instruction has executed.

* bpo-43693: Eliminate unused "fast locals". (gh-26587)Eric Snow2021-06-152-8/+2
| | | | | Currently, if an arg value escapes (into the closure for an inner function) we end up allocating two indices in the fast locals even though only one gets used. Additionally, using the lower index would be better in some cases, such as with no-arg `super()`. To address this, we update the compiler to fix the offsets so each variable only gets one "fast local". As a consequence, now some cell offsets are interspersed with the locals (only when an arg escapes to an inner function). https://bugs.python.org/issue43693

* bpo-44378: Fix a compiler warning in Py_IS_TYPE() (GH-26644)Victor Stinner2021-06-111-1/+3
| | | | Py_IS_TYPE() no longer uses Py_TYPE() to avoid a compiler warning: no longer cast "const PyObject*" to "PyObject*".

* bpo-44348: Move trace-info to thread-state (GH-26623)Mark Shannon2021-06-101-0/+6

* bpo-43693: Un-revert commit f3fa63e. (#26609)Eric Snow2021-06-083-6/+16
| | | | | | | | | This was reverted in GH-26596 (commit 6d518bb) due to some bad memory accesses. * Add the MAKE_CELL opcode. (gh-26396) The memory accesses have been fixed. https://bugs.python.org/issue43693

* bpo-44348: Revert "bpo-39573: Py_TYPE becomes a static inline function ↵Pablo Galindo2021-06-081-8/+2
| | | | | | (GH-26493)" (GH-26596) This reverts commit f3fa63ec75fdbb4a08a10957a5c631bf0c4a5970 as is causing crashes in some Windows tests in the buildbots.
* bpo-43693: Silence some compiler warnings. (gh-26588)Eric Snow2021-06-072-5/+2
| | | | | | | The plan is to eventually make PyCodeObject opaque in the public C-API, with the full struct moved to Include/internal/pycore_code.h. _PyLocalsPlusKinds and _PyLocalsPlusKind started off there but were needed on PyCodeObject, hence the duplication. This led to warnings with some compilers. (Apparently it does not trigger a warning on my install of GCC.) This change eliminates the superfluous typedef. https://bugs.python.org/issue43693
* bpo-43693: Add the MAKE_CELL opcode and interleave fast locals offsets. ↵Eric Snow2021-06-073-6/+16
| | | | | | | (gh-26396) This moves logic out of the frame initialization code and into the compiler and eval loop. Doing so simplifies the runtime code and allows us to optimize it better. https://bugs.python.org/issue43693
