| | | | | | (GH-26493)" (GH-26596) This reverts commit f3fa63ec75fdbb4a08a10957a5c631bf0c4a5970 as is causing crashes in some Windows tests in the buildbots.
* bpo-43693: Add the MAKE_CELL opcode and interleave fast locals offsets. ↵Eric Snow2021-06-071-0/+8

* bpo-39573: Py_TYPE becomes a static inline function (GH-26493)Victor Stinner2021-06-032-3/+38
| | | | | Convert the Py_TYPE() and Py_SIZE() macros to static inline functions. The Py_SET_TYPE() and Py_SET_SIZE() functions must now be used to set an object type and size.
* bpo-43693: Add new internal code objects fields: co_fastlocalnames and ↵Eric Snow2021-06-031-3/+2
| | | | | | | | | | | | | | | | | co_fastlocalkinds. (gh-26388) A number of places in the code base (notably ceval.c and frameobject.c) rely on mapping variable names to indices in the frame "locals plus" array (AKA fast locals), and thus opargs. Currently the compiler indirectly encodes that information on the code object as the tuples co_varnames, co_cellvars, and co_freevars. At runtime the dependent code must calculate the proper mapping from those, which isn't ideal and impacts performance-sensitive sections. This is something we can easily address in the compiler instead. This change addresses the situation by replacing internal use of co_varnames, etc. with a single combined tuple of names in locals-plus order, along with a minimal array mapping each to its kind (local vs. cell vs. free). These two new PyCodeObject fields, co_fastlocalnames and co_fastllocalkinds, are not exposed to Python code for now, but co_varnames, etc. are still available with the same values as before (though computed lazily). Aside from the (mild) performance impact, there are a number of other benefits: * there's now a clear, direct relationship between locals-plus and variables * code that relies on the locals-plus-to-name mapping is simpler * marshaled code objects are smaller and serialize/de-serialize faster Also note that we can take this approach further by expanding the possible values in co_fastlocalkinds to include specific argument types (e.g. positional-only, kwargs). Doing so would allow further speed-ups in _PyEval_MakeFrameVector(), which is where args get unpacked into the locals-plus array. It would also allow us to shrink marshaled code objects even further. https://bugs.python.org/issue43693

* bpo-43795: Remove Py_FrozenMain from the Limited API & Stable ABI (GH-26241)Petr Viktorin2021-05-252-1/+4
| | | | | | | | | | | Py_FrozenMain was added to the Limited C API in [bpo-42591]() (3.10.0a4); but to fix that issue it would be enough to add it to the regular C API. The function is undocumented, tests were added very recently ([bpo-44131]()), and most importantly, it is not present in all builds of Python, as the linker sometimes omits it as unused. It should be added back when these issues are fixed. Note that this does not affect Python's regular C API.
