NanoThreads 11
by simonwittber＠gmail.com 04 Oct '05

04 Oct '05

NanoThreads v11 NanoThreads allows the programmer to simulate concurrent processing using generators as tasks, which are registered with a scheduler. While the scheduler is running, a NanoThread can be: - paused - resumed - ended (terminate and call all registered exit functions) - killed (terminate and do not call any registered exit functions) - preempted to the top of the execution queue New in v11: A NanoThread task can now yield control using 'yield nanothreads.UNBLOCK', which performs the next iteration of the task in a separate, OS level thread. This allows the scheduler to keep running other tasks, while the nanothread is, for example, performing CPU blocking IO, or calling some time consuming function. Sw.

ANN: Paste Packages 0.3
by Ian Bicking 02 Oct '05

02 Oct '05

I'm pleased to release the first official packaging of the Paste suite of tools. I'm starting at 0.3 -- less committal than 1.0, but more confident than 0.1... just right for now. Python Paste aims brings consistency to Python web development and web application installation, providing tools for both developers and system administrators. Paste includes these packages: Paste (Core): A set of tools for building web frameworks, built on WSGI. Paste Deploy: A configuration loader for composing WSGI applications into application instances (and implicitly a sort of application server). Paste Script: A pluggable script (paster) for application development, particularly web development. Paste WebKit: A reimplementation of the Webware API, implemented with the tools in Paste Core, the configuration of Paste Deploy, and the application setup of Paste Script. Wareweb: An alpha framework taking some of the ideas from WebKit, and presenting them in a simplified and more decoupled form.

MMA Musical MIDI Accompaniment version: Beta 0.16
by Bob van der Poel 02 Oct '05

02 Oct '05

I'm pleased to announce the release of my program mma - Musical MIDI Accompaniment version: Beta 0.16 MMA is a accompaniment generator -- it creates midi tracks for a soloist to perform with. User supplied files contain pattern selections, chords, and MMA directives. MMA is very versatile and generates excellent tracks. It comes with an extensive user-extendable library with a variety of patterns for various popular rhythms, an extensive user manual, and many demo songs. MMA is a command line driven program. It creates MIDI files which need a sequencer or MIDI file play program. MMA is written in Python. You'll need Python 2.3 (or later) for MMA to function. MMA is supplied in 4 tar.gz archives. Included: mma-bin -- the main script and library files. mma-html -- documentation in HTML format. mma-pdf -- documentation in PDF format. mma-songs -- a collection of about 230 songs in MMA format. If you get all four download packages the total size is still less than 1.5 megabytes. MMA is currently in final BETAs. We are hoping for a 1.0 release in winter 2005. Right now we need help in debugging the program, creating songs for distribution, and new and improved library files. Best of all, MMA is free. It is released under the terms of the GNU General Public License. It has been developed on a Linux platform, but should be usable on just about any system. A detailed page now exists on our web site on how-to install on a Windows system. MMA is available on my personal home page: http://mypage.uniserve.com/~bvdp/mma/ If you have any questions or comments, please send them to: bvdp(a)uniserve.com Beta 0.16: Lots of little bug fixes, new SWINGMODE, more note offset and length options, NOTESPAN directive, better KEYSIG support, enhanced VOLUME options, negative offsets (prior bar) in patterns. You really need to read the DOCS for all this! Comments appreciated! -- Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bvdp(a)uniserve.com WWW: http://mypage.uniserve.com/~bvdp

Zope 3.1.0 released!
by Stephan Richter 02 Oct '05

02 Oct '05

The Zope 3 development team is proud to announce Zope 3.1.0 final. Zope 3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. It is in our opinion that Zope 3.1 is more than ready for production use, which is why we decided to drop the 'X' for experimental from the name. We will also continue to work on making the transition between Zope 2 and Zope 3 as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in the form of Five. Now that we have a release that we would like to declare stable next week, we are looking for translators, who translate Zope 3 into their favorite language! We are utilizing the Rosetta system from Ubuntu for managing those translations. If you are not familiar with Rosetta, please send us a mail to zope3-dev(a)zope.org and we get you set up. Downloads http://zope.org/Products/Zope3/ Installation instructions for both Windows and Un*x/Linux are now available in the top level 'README.txt' file of the distribution. The binary installer is recommended for Windows. Zope 3.1 requires Python 2.3.5 or 2.4.1 to run. You must also have zlib installed on your system. Most Important Changes Since 3.0 - New Pluggable Authentication Utility (PAU), which is similar in philosophy to the Zope 2 PAS. The following features are available in the in the basic PAU facility: + Credentials Plugins: Basic HTTP Auth, Session + Authenticator Plugins: Principal Folder, Group Folder For a detailed description of the pluggable authentication utility, see 'zope/app/authentication/README.txt'. - Major simplifications to the component architecture: + Removal of the concept of a service. All outstanding services were converted to utilities: Error Reporting, FSSync, Authentication. + Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar. + Local registrations can now only have two states: active and inactive. This simplified the code so much, that 'zope.app.utility', 'zope.app.registration' and 'zope.app.site' were all merged into 'zope.app.component'. + Implemented menus as utilities. The API also supports sub-menus now. + Implemented views as adapters. Skins and layers are now simply interfaces that the request provides. - Added an integer-id facility for assigning integer identifiers to objects. - Added basic catalog and index frameworks. - Added "sources", which are like vocabularies except that they support very large collections of values that must be searched, rather than browsed. - Created a new granting UI that allows advanced searching of principal sources. - Implemented a generic user preferences systsem that was designed to be easily used in TALES expressions and via Python code. Preferences can be edited via 'http://localhost:8080/++preferences++/'. A demo of the preferences can be found at:: http://svn.zope.org/Zope3/trunk/src/zope/app/demo/skinpref/ - ZCML now supports conditional directives using the 'zcml:condition' attribute. The condition is of the form "verb argument". Two verbs, 'have feature' and 'installed module' are currently implemented. Features can be declared via the 'meta:provides' directive. - Improved API doctool: Code Browser now shows interfaces, text files and ZCML files; the new Book Module compiles all available doctext files into an organized book; the new Type Module lets you browser all interface types and discover interfaces that provide types; views are shown in the interface details screen; views and adapters are categorized into specific, extended and generic; user preferences allow you to customize certain views; 3rd party modules can now be added to the Code Browser. - Improved I18n-based number and datetime formatting by integrating 'pytz' for timezone support, implementing all missing format characters, and reinterpreting the ICU documentation to correctly parse patterns. - Added '++debug++' traversal adapter that allows you to turn on debugging flags in 'request.debug'. Currently the following flags are defined: source, tal, errors. - Improved logout support. - Developed a generic 'browser:form' directive. It is pretty much the same as the 'browser:editform' directive, except that the data is not stored on some context or adapted context but sent as a dictionary to special method (by default). For a complete list of changes see the 'CHANGES.txt' file.

ZRS Now Available for FREE 30-day Evaluation
by Brian Lloyd 30 Sep '05

30 Sep '05

Hi all, We are happy to announce that Zope Corporation is now offering Zope Replication Services (ZRS) in a 30-day evaluation format! For more information and to download the evaluation release, visit: http://customers.zope.com/ZRS/ About ZRS: Zope Replication Services (ZRS) increases the reliability of all Zope enterprise clusters and eliminates the storage system as a single point of failure. Sites with high availability requirements must manage planned and unplanned downtimes. Planned outages include system maintenance, software / operating system upgrades, and backups. Unplanned outages include hardware and network failures. ZRS reduces the downtime associated with these events by replicating and distributing mission-critical data storage across distinct physical storages (possibly in distinct geographic locations). Should a primary storage fail, a secondary storage can take its place. Secondary servers can be taken off-line at any time to undergo repairs, backups, or system upgrades. When a secondary returns to service, it automatically resynchronizes with the primary server. ZRS also improves scalability since secondary servers can optionally provide additional read-only ZEO connections while maintaining their replication functions. ZEO client storages can be configured to connect to any available secondary, and can be load-balanced among the available secondary ZRS servers to implement highly-available and highly-scalable Zope clusters. ZRS is a 'battle-tested' solution that has provided the high-availability and disaster recovery solution critical to large-scale public and internal Zope deployments for years. Premier brands including the VIACOM radio and television group, AARP, Community Newspaper Holdings Inc. (CNHI), and the Joint Intelligence Center, Pacific (JICPAC) rely on ZRS to ensure reliability and scalability for their mission-critical Web sites. The 30-day evaluation release allows organizations to install and operate ZRS on up to five primary ZODB servers and on an unlimited number of secondary servers for up to thirty days. The current evaluation release (ZRS 1.4.2) is compatible with Zope versions 2.4 - 2.7. Full releases of ZRS compatible with Zope 2.8.x and Zope 3.x are also available.
