- PROPOSAL: A Generic Python Object Interface for Python C Modules\r
-\r
-Problem\r
-\r
- Python modules written in C that must access Python objects must do\r
- so through routines whose interfaces are described by a set of\r
- include files. Unfortunately, these routines vary according to the\r
- object accessed. To use these routines, the C programmer must check\r
- the type of the object being used and must call a routine based on\r
- the object type. For example, to access an element of a sequence,\r
- the programmer must determine whether the sequence is a list or a\r
- tuple:\r
-\r
- if(is_tupleobject(o))\r
- e=gettupleitem(o,i)\r
- else if(is_listitem(o))\r
- e=getlistitem(o,i)\r
-\r
- If the programmer wants to get an item from another type of object\r
- that provides sequence behavior, there is no clear way to do it\r
- correctly.\r
-\r
- The persistent programmer may peruse object.h and find that the\r
- _typeobject structure provides a means of invoking up to (currently\r
- about) 41 special operators. So, for example, a routine can get an\r
- item from any object that provides sequence behavior. However, to\r
- use this mechanism, the programmer must make their code dependent on\r
- the current Python implementation.\r
-\r
- Also, certain semantics, especially memory management semantics, may\r
- differ by the type of object being used. Unfortunately, these\r
- semantics are not clearly described in the current include files.\r
- An abstract interface providing more consistent semantics is needed.\r
-\r
-Proposal\r
-\r
- I propose the creation of a standard interface (with an associated\r
- library of routines and/or macros) for generically obtaining the\r
- services of Python objects. This proposal can be viewed as one\r
- components of a Python C interface consisting of several components.\r
-\r
- From the viewpoint of C access to Python services, we have (as\r
- suggested by Guido in off-line discussions):\r
-\r
- - "Very high level layer": two or three functions that let you exec or\r
- eval arbitrary Python code given as a string in a module whose name is\r
- given, passing C values in and getting C values out using\r
- mkvalue/getargs style format strings. This does not require the user\r
- to declare any variables of type "PyObject *". This should be enough\r
- to write a simple application that gets Python code from the user,\r
- execs it, and returns the output or errors. (Error handling must also\r
- be part of this API.)\r
-\r
- - "Abstract objects layer": which is the subject of this proposal.\r
- It has many functions operating on objects, and lest you do many\r
- things from C that you can also write in Python, without going\r
- through the Python parser.\r
-\r
- - "Concrete objects layer": This is the public type-dependent\r
- interface provided by the standard built-in types, such as floats,\r
- strings, and lists. This interface exists and is currently\r
- documented by the collection of include files provided with the\r
- Python distributions.\r
-\r
- From the point of view of Python accessing services provided by C\r
- modules:\r
-\r
- - "Python module interface": this interface consist of the basic\r
- routines used to define modules and their members. Most of the\r
- current extensions-writing guide deals with this interface.\r
-\r
- - "Built-in object interface": this is the interface that a new\r
- built-in type must provide and the mechanisms and rules that a\r
- developer of a new built-in type must use and follow.\r
-\r
- This proposal is a "first-cut" that is intended to spur\r
- discussion. See especially the lists of notes.\r
-\r
- The Python C object interface will provide four protocols: object,\r
- numeric, sequence, and mapping. Each protocol consists of a\r
- collection of related operations. If an operation that is not\r
- provided by a particular type is invoked, then a standard exception,\r
- NotImplementedError is raised with a operation name as an argument.\r
- In addition, for convenience this interface defines a set of\r
- constructors for building objects of built-in types. This is needed\r
- so new objects can be returned from C functions that otherwise treat\r
- objects generically.\r
-\r
-Memory Management\r
-\r
- For all of the functions described in this proposal, if a function\r
- retains a reference to a Python object passed as an argument, then the\r
- function will increase the reference count of the object. It is\r
- unnecessary for the caller to increase the reference count of an\r
- argument in anticipation of the object's retention.\r
-\r
- All Python objects returned from functions should be treated as new\r
- objects. Functions that return objects assume that the caller will\r
- retain a reference and the reference count of the object has already\r
- been incremented to account for this fact. A caller that does not\r
- retain a reference to an object that is returned from a function\r
- must decrement the reference count of the object (using\r
- DECREF(object)) to prevent memory leaks.\r
-\r
- Note that the behavior mentioned here is different from the current\r
- behavior for some objects (e.g. lists and tuples) when certain\r
- type-specific routines are called directly (e.g. setlistitem). The\r
- proposed abstraction layer will provide a consistent memory\r
- management interface, correcting for inconsistent behavior for some\r
- built-in types.\r
