[issue39573] Make PyObject an opaque structure in the limited C API

STINNER Victor added the comment: To make PyObject opaque, we would have to convert Py_INCREF() and Py_DECREF() to opaque function calls. Example: #define Py_XINCREF(op) Py_IncRef(op) #define Py_XDECREF(op) Py_DecRef(op) Benchmarks should be run to measure to overhead and balance the

[issue36843] AIX build fails with failure to get random numbers

Michael Felt added the comment: FYI: I was contacted this week by someone with this problem. The problem was resolved after they updated AIX (was 7100-04-00-). Please note: any oslevel -s reporting six zeros at the end needs the SP that is released in parallel with the base.

[issue39576] Surprising MemoryError in `decimal` with MAX_PREC

Mark Dickinson added the comment: Agreed that this seems surprising. @Vedran: Trailing zeros in a Decimal object are significant, so `Decimal("2.0")` and `Decimal("2.00")` are different (equal, but different). The rules about the "ideal exponent" of the result of an arithmetic operation

[issue37413] Deprecate sys._enablelegacywindowsfsencoding()?
