bpo-38316: describe co_stacksize a little bit better #16983

hmm, now that I think about this more. I think more appropriate wording would be:

co_stacksize is the largest size the stack will grow to when executing the function;

@ammaraskar can you check it now?

ammaraskar

LGTM with final suggestion

Doc/reference/datamodel.rst

ammaraskar · 2019-11-15T23:19:34Z

@vstinner Would you mind taking a look at this?

vstinner

Objects/frameobject.c allocates an array of code->co_stacksize + code->co_nlocals + ncells + nfrees items. The array size doesn't chagne during the execution of the function, it's not like x86 machine mode which manipulates the stack pointer (SP) register and use PUSH/POP.

:attr:co_stacksize is the required stack size (including local variables)

So this definition sounds wrong to me.

Instead, I suggest this definition:

:attr:`co_stacksize` is the required stack size

=> just remove (including local variables).
