My suggestion is therefore to replace PyOS_InputHook by two functions PyOS_AddInputHook and PyOS_RemoveInputHook, and let Python keep track of which hooks are installed. This way, an extension module can add a hook function without having to worry about other extension modules trying to use the same hook.
Any comments? Would I need to submit a PEP for this proposal?
Because this is only for the C API, your best bet is to write a patch and submit it to SF. If people whine or it gets rejected, then write a PEP.
I did modify the readline module that hooks this and can call back to a Python function. There are also methods for installing and removing the Python function. I did this for a different reason. I need Python signal handlers to run, and they don't run when the execution path is currently in some C code (such as readline). The hook forces the interpreter to run, and check for signals as a side effect. Using this I can be sitting in raw_input(), or interactive mode, and signal handlers are still run.
If you want it, let me know.
Actually, the modded readline module is part of pyNMS, on sourceforge.
