New submission from Mark Shannon : In https://bugs.python.org/issue44032 we moved most of the data in the frame stack, that is the locals, stack, and "specials" (globals, builtins, code etc), from the heap allocated stack to a (mostly) contiguous array in memory. That offered som

2021-07-07 Thread Mark Shannon
Mark Shannon added the comment: This is a tricky one. Which is the "correct" line appears to be subjective. I'm inclined to leave it as is, as the tracing sequence seems better in the case of method chaining. See https://github.com/python/cpython/blob/main/Lib/test/test_compi

2021-07-07 Thread Mark Shannon
New submission from Mark Shannon : This breaks a key invariant of PEP 659. Inserting `assert(cframe.use_tracing == 0);` at the top of all quickened instructions results in several failures when running the test suite. -- assignee: Mark.Shannon components: Interpreter Core messages

Mark Shannon added the comment: I suspect that the 0.1% increase is noise. The size of importlib.h etc show a small decrease, suggesting that the information content of the code object has *decreased*. After all, the qualname has to stored somewhere and moving it from caller to callee

Mark Shannon added the comment: I think this is a worthwhile improvement. A few comments on this issue and your PR. 1. We already have qualified names on functions and generators and those can be modified by @decorators. In those cases, the code object and the function would disagree. Code
