Grok 0.14 released!

The Grok team is happy to announce the release of Grok 0.14! This release is available on PyPI and a new index of specific versions of packages used by this release has been frozen at http://grok.zope.org/releaseinfo/grok-0.14.cfg. This means that new projects created with grokproject will start using this release right away. This release is the first release of Grok that officially supports Python 2.5 (besides Python 2.4 itself). The main focus of this release has been a restructuring of Grok, spinning off packages that can now be used independently in Zope 3 projects as well as in Zope 2 (through five.grok): * Spin off of grokcore.view - support for views is now maintained in this package. * Spin off of grokcore.security - support for security declarations is now maintained here * Spin off of grokcore.formlib - support for zope.formlib based forms * Spin off of grokui.admin - the admin UI is now distributed separately, but grokproject automatically will include it when you create a new grok project. * the grok.Skin baseclass is now gone and has been simplified with the grok.skin directive that can be placed on a layer instead. To upgrade an existing project from 0.13 to 0.14 you have to: * include grokui.admin explicitly as a dependency in your setup.py * update the versions.cfg in your project with the version from http://grok.zope.org/releaseinfo/grok-0.14.cfg * modify uses of grok.Skin to use the grok.skin directive For the detailed changelog, see Grok's PyPI entry page. For detailed upgrade notes, including how to change your application, see http://grok.zope.org/project/upgrade-notes For installation instructions and much more on how to use Grok, see the Grok tutorial: http://grok.zope.org/documentation/book We hope to hear from you! If you enjoy Grok, please subscribe to the grok-dev mailing list and join us in the #grok channel on irc.freenode.net.

zc.async 1.5.0
by Gary Poster 22 Sep '08

http://pypi.python.org/pypi/zc.async =========== What is it? =========== The ``zc.async`` package provides **an easy-to-use Python tool that schedules work persistently and reliably across multiple processes and machines.** For instance... - *Web apps*: maybe your web application lets users request the creation of a large PDF, or some other expensive task. - *Postponed work*: maybe you have a job that needs to be done at a certain time, not right now. - *Parallel processing*: maybe you have a long-running problem that can be made to complete faster by splitting it up into discrete parts, each performed in parallel, across multiple machines. - *Serial processing*: maybe you want to decompose and serialize a job. High-level features include the following: - easy to use; - flexible configuration, changeable dynamically in production; - reliable; - supports high availability; - good debugging tools; - well-tested; and - friendly to testing. While developed as part of the Zope project, zc.async can be used stand-alone. ================= How does it work? ================= The system uses the Zope Object Database (ZODB), a transactional, pickle-based Python object database, for communication and coordination among participating processes. zc.async participants can each run in their own process, or share a process (run in threads) with other code. The Twisted framework supplies some code (failures and reactor implementations, primarily) and some concepts to the package. ====================== Where can I read more? ====================== Quickstarts and in-depth documentation are available in the package and in the `new and exciting on-line documentation`_. .. _`new and exciting on-line documentation`: http://packages.python.org/zc.async/1.5.0/ Thanks for your attention Gary
