Porcupine Description

Open source web app server that provides front-end and back-end technologies for building modern data-centric Web 2.0 applications Porcupine is an open-source Python based web application server that provides front-end and back-end revolutionary technologies for building modern data-centric Web2.0 applications.Many of the tasks required for building web applications as you know them, are either eliminated or simplified. For instance, when developing a Porcupine application you don't have to design a relational database. You only have to design and implement your business objects as Python classes, using the building blocks provided by the framework (data-types). Porcupine integrates a native object database, therefore the overheads required by an object-relational mapping technique when updating or retrieving a single object are removed.Porcupine comes with three applications pre-installed:· User and Groups Management· POQL Query Performer. A good testbed for your queries, although in a very early development stage.· HyperSearch Here are some key features of "Porcupine": · Embedded hierarhical object database with transaction support based on Berkeley DB · The Porcupine Object Query Language (powered by David Beazley's PLY parsing tools) · Configurable in-memory object cache · Simple role based security · Support for custom data-types · Custom event handlers per content class · Integrates QuiX, inno:script's JavaScript framework · Remote methods (Web Methods) bound to content classes become directly accessible over HTTP · Compiled Python Server Pages · Support for pre and post-processing filters (GZIP, i18n, impersonation and many other filters are offered out of the box) · Web Methods can be secured with policies by using the provided pre-processing filter · Connectivity with WSGI, CGI enabled web servers. A MOD_PYTHON connector is also available. · Single file deployment. Use the pakager utility to include all of your application files and object definitions in a single file. Installation is done by the same utility using a single command. · Full UTF-8 support · Runs on Mac OS, Linux, and Windows NT · Easy to learn API · Supported protocols: HTTP, XML-RPC Requirements: · Web server · Web connector What's New in This Release: · NEW: Object indexing support including unique indexes per container. Currently, · the indexes are used for common database usage patterns such as getting the · children of a container, but not yet fully leveraged by OQL. · NEW: Added multi-processing support for the asynchrounous TCP-IP services · (requires Python 2.6). · NEW: Added conditional Etag support by using the provided · "porcupine.filters.etag" decorator or the "porcupine.filters.caching.Etag" · pre-processing filter. · NEW: New database and cookie based session managers. · NEW: Added support for shortcuts by using the new · "porcupine.systemObjects.Shortcut" content type. · NEW: Cascade deletes for Relator1 and RelatorN data types. · NEW: QuiX now includes a lightweight rich text editor based on · Cameron Adams' work (http://www.themaninblue.com/). · NEW: QuiX now supports auto sized labels, icons, buttons and boxes. The · dimensions of these kind of widgets are automatically adjusted based · on their contents. · NEW: Added themes support for QuiX. · NEW: New "QuiX.queryString" function for getting query string parameters. · NEW: New "QuiX.baseUrl" setting that contains the toolkit's root folder. · NEW: QuiX now includes a JSON parser. See "QuiX.parsers.JSON". · NEW: QuiX now has a client side persistence module based on PersistJS · (http://pablotron.org/?cid=1557). · NEW: New "QuiX.utils.hashlib" module. · NEW: Ability for having persistent datasets on the client side by using smart · conditional Etags. · NEW: QuiX now supports IE 8, Safari 4 and Opera 9. · NEW: New method "setValue" for QuiX select lists. · NEW: New "hbox" and "vbox" shortcuts for horixontal and vertical boxes. · OPT: QuiX now has namespaces (i.e XButton is now QuiX.ui.Button). · The old naming convention is kept for backwards compatibility. · OPT: "db.getItem" no longer raises an ObjectNotFound exception. Instead None is · returned. · OPT: "relCc" attribute of relators and references now accepts base classes. · OPT: server side XMLRPC encoding speed improvements. · OPT: Porcupine OQL is now using PLY 2.5. · OPT: New implementation of "QuiX.innerText" function. · OPT: The "setExpiration" method of the HttpResponse class now accepts a · "cache_type" optional argument. The default value is "private". · OPT: New refactored transactions. Transactions are now non-blocking by using · the DB_TXN_NOWAIT flag. · OPT: Otimized session management. · OPT: Optimized asyncore loop by using longer timeouts. · OPT: Do not retrieve session info for static files. · OPT: Ability to set widget overflow values per axis i.e "auto hidden". · OPT: "porcupineadmin.py -c" now performs disaster recovery. · OPT: The "_safetype" class attribute of data type classes now accepts a list · of the allowed Python types. · OPT: If the bsddb module is not present then try to import bsddb3, since bsddb · is removed from the latest Python versions. · OPT: The "@db.transactional" decorator now accepts an optional "nosync" argument · for having faster but non durable transactions. · OPT: Ability to have the data and log files in different locations by using · the "bdb_log_dir" setting in the porcupine configuration file. · OPT: QuiX now includes a universal base Widget script. · FIX: Fixed QuiX's "onunload" event (it was fired only when the destroy method · of a widget was explicitly called) · FIX: Fixed __props__ generation when using codegen. · FIX: Fixed internal redirection. · FIX: "padding" is now a valid parameter for QuiX windows. · FIX: Fixed hidden buttons. · DEP: "HttpContext.current()" is deprecated. Use "from porcupine import context" · instead. · DEP: Containers no longer have the "_subfolders" and "_items" attributes. This · kind of info is now derived from indexes allowing hundrends of thousands · descendants with no perfomance penalty. · DEP: Most of the API methods are deprecrated due to PEP8 alignment. Check · the server's log for deprecated calls. · DEP: Removed all __slots__ attributes from all schema related classes. · DEP: "porcupine.core.servicetypes.asyncBaseServer.BaseRequest" is now · "porcupine.core.networking.request.BaseRequest" · DEP: "porcupine.security.objectAccess.getAccess" is deprecated. · Use "porcupine.utils.permsresolver.get_access" instead. · DEP: QuiX boxes are no longer redrawn when removing a child widget. · The developer should take care of this. · DEP: "QuiX.getOS" is deprecated use "QuiX.utils.BrowserInfo.OS" instead.
