  • SIG for Development of Persistence and Transaction Frameworks

    ...object changes or save objects. Applications should not have to explicitly query most objects. Typically, some "root" objects will be explicitly retrieved and other objects will be retrieved through normal Python object traversal. Application objects should not contain storage code, such as SQL statements or file operations, needed to provide their persistence. Application code may need to contain code to generate persistence-related events, but even these sho...

    ...Objective-C/NeXTSTEP/OpenStep SIG on Python bindings for Objective-C/NeXTSTEP/OpenStep This sig has been retired. New postings to the mailing list will be rejected, but the archives of the old list are still available for perusal. See the SIGs home page for info about active and inactive lists. The Python / Objective C connection lives on in the PyObjC project at SourceForge! The purpose of this SIG is to complete a Python extension module binding the Objective-C and P...

  • Debugging Reference Count Problems

    ...object is created, it already comes with a reference count of one. The API manual says of this situation that you "own" a reference. (You don't own the object -- it may be shared. E.g. small integers and short strings are cached and shared aggressively -- but that doesn't affect whether you own a reference to them.) Many routines that extract objects from other objects also give you the responsibility of owning a reference to the object, e.g. PyObject_GetAttr() and PyObject_GetItem()....

  • Objective-C SIG Status

    Objective-C SIG Status Objective-C SIG Status Lele Gaifax has recently posted a much improved module to provide Python bindings to the Objective-C runtime. Bill Bumgarner is archiving the latest releases, along with quad-fat binaries and other useful Objective-C/Python stuff. Bill's archive is available at ftp://ftp.thoughtport.net/pub/next/lang/

    ...objects and data mining. ZSQLCatalog solves several major problems often encountered in Enterprise applications: locks, slow reports, and inconsistent transactions. Most Enterprise applications use tables in a relational database to store data. In ERP5 data is stored instead in Zope's object database. Zope eliminates the need for storage adapters or attribute mappings by providing transparent persistence of Python objects. Zope also speeds up object access: Reading the Zope object database is 10...

(each device running a GZF Client). Regarding these Shared objects one can think of both simple User Interface objects or complex objects related to for example the operations of a nuclear reactor. In both instances these objects are handled identically by the core of the GravityZoo Framework. Identically,...

The Pilot lets the user manipulate object data, and links between objects, by clicking on the respective item (see Figure A). This click opens an object editor for modification of attributes. The object editor is parameterized with the type of object in the model. The code for drawing the object model, for the object editor, and for extracting the help information, is all part of the framew...

The subclass __new__ can do two things to affect the resulting object: pass different arguments to the base class __new__, and modify the resulting object after it's been created (for example to initialize essential instance variables). __new__ must return an object. There's nothing that requires that it return a new object that is an instance of its class argument, although that is the convention. If you return an existing object, the constructor call will still call its __i...
