Big internal change that should have no external effects: unify the
'slotdef' structure typedef and 'struct wrapperbase'. By adding the wrapper docstrings to the slotdef structure, the slotdefs array can serve as the data structure that drives add_operators(); the wrapper descriptor contains a pointer to slotdef structure. This replaces lots of custom code from add_operators() by a loop over the slotdefs array, and does away with all the tab_xxx tables.

/* This function is called by PyType_Ready() to populate the type's

dictionary with method descriptors for function slots. For each

||||
function slot (like tp_repr) that's defined in the type, one or
|
||||
more corresponding descriptors are added in the type's tp_dict
|
||||
dictionary under the appropriate name (like __repr__). Some
|
||||
function slots cause more than one descriptor to be added (for
|
||||
example, the nb_add slot adds both __add__ and __radd__
|
||||
descriptors) and some function slots compete for the same
|
||||
descriptor (for example both sq_item and mp_subscript generate a
|
||||
__getitem__ descriptor). This only adds new descriptors and
|
||||
doesn't overwrite entries in tp_dict that were previously
|
||||
defined. The descriptors contain a reference to the C function
|
||||
they must call, so that it's safe if they are copied into a
|
||||
subtype's __dict__ and the subtype has a different C function in
|
||||
its slot -- calling the method defined by the descriptor will call
|
||||
the C function that was used to create it, rather than the C

/* This function is called by PyType_Ready() to populate the type's
|
||||
dictionary with method descriptors for function slots. For each
|
||||
function slot (like tp_repr) that's defined in the type, one or
|
||||
more corresponding descriptors are added in the type's tp_dict
|
||||
dictionary under the appropriate name (like __repr__). Some
|
||||
function slots cause more than one descriptor to be added (for
|
||||
example, the nb_add slot adds both __add__ and __radd__
|
||||
descriptors) and some function slots compete for the same
|
||||
descriptor (for example both sq_item and mp_subscript generate a
|
||||
__getitem__ descriptor). This only adds new descriptors and
|
||||
doesn't overwrite entries in tp_dict that were previously
|
||||
defined. The descriptors contain a reference to the C function
|
||||
they must call, so that it's safe if they are copied into a
|
||||
subtype's __dict__ and the subtype has a different C function in
|
||||
its slot -- calling the method defined by the descriptor will call
|
||||
the C function that was used to create it, rather than the C
|
||||
function present in the slot when it is called. (This is important
|
||||
because a subtype may have a C function in the slot that calls the
|
||||
method from the dictionary, and we want to avoid infinite recursion
|
||||
here.) */
