[issue38946] IDLE on macOS 10.15 Catalina does not open double-clicked files if app already launched

Terry J. Reedy added the comment: By design, IDLE should only allow one editor instance per file for a given python-IDLE process. "$ python3 fails.py" opens a new python-IDLE process, independent of existing processes. It is possible that double-clicking good.py multiple times opens a new

[issue38360] single-argument form of -isysroot should be supported

Joshua Root added the comment: That ValueError I mentioned causes build failures for extension modules whenever the CFLAGS in sysconfig contains an -isysroot flag in the single arg form. We ran into it a lot in MacPorts on Mojave and Catalina. So I would consider it a bug, and would prefer
