From 4710c53dcad1ebf3755f3efb9e80ac24bd72a9b2 Mon Sep 17 00:00:00 2001 From: darylm503 Date: Mon, 16 Apr 2012 22:12:42 +0000 Subject: AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site. These files are a subset of the python-2.7.2.tgz distribution from python.org. Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.

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