* bpo-43693: Add new internal code objects fields: co_fastlocalnames and ↵Eric Snow2021-06-031-4/+6
| | | | | | | | | | | | | | | | | 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-44206: Add a version number to dictionary keys (GH-26333)Mark Shannon2021-05-281-1/+1

* bpo-44180: Fix edge cases in invalid assigment rules in the parser (GH-26283)Pablo Galindo2021-05-211-0/+2
| | | | | | | | | | | | | | | The invalid assignment rules are very delicate since the parser can easily raise an invalid assignment when a keyword argument is provided. As they are very deep into the grammar tree, is very difficult to specify in which contexts these rules can be used and in which don't. For that, we need to use a different version of the rule that doesn't do error checking in those situations where we don't want the rule to raise (keyword arguments and generator expressions). We also need to check if we are in left-recursive rule, as those can try to eagerly advance the parser even if the parse will fail at the end of the expression. Failing to do this allows the parser to start parsing a call as a tuple and incorrectly identify a keyword argument as an invalid assignment, before it realizes that it was not a tuple after all.
* bpo-44032: Move data stack to thread from FrameObject. (GH-26076)Mark Shannon2021-05-211-3/+17
