ANN: Release of a new ViTables video
by Vicent Mas (V+) Jan. 31, 2008

Jan. 31, 2008

=============================== Release of a new ViTables video =============================== `Carabos <http://www.carabos.com/>`_ is very happy to announce the second video of the series dedicated to introducing the main features of ViTables to the public. http://www.carabos.com/products/videos/vitables-2-queries `ViTables <http://www.carabos.com/products/vitables>`_ is a GUI for `PyTables <http://www.pytables.org>`_. It allows to open arbitrarely large PyTables and HDF5 files and browse their data and metadata in a variety of ways. This second video explains in depth how to quickly query multi-billion row tables using ViTables in combination with OPSI [1]_, the powerful indexing engine that comes with PyTablesPro. The covered topics are: * how to do queries involving several fields a.k.a complex queries * how to include the indexes of the selected rows in a query result * detailed description of the queries dialog * how indexing fields with OPSI affects the speed of queries It has a running length of about 8 minutes, so you can watch it during any short break. We would like to hear your opinion on the video so we can do it better the next time. We are also open to suggestions for the topics of future videos. ..

ANN: epydoc 3.0
by Edward Loper Jan. 30, 2008

Jan. 30, 2008

Announcing epydoc 3.0 ~~~~~~~~~~~~~~~~~~~~~ Webpage: http://epydoc.sourceforge.net/ Download: http://tinyurl.com/yoo6d7 About epydoc ~~~~~~~~~~~~ Epydoc is a tool for generating API documentation for Python modules, based on their docstrings. A lightweight markup language called epytext can be used to format docstrings, and to add information about specific fields, such as parameters and instance variables. Epydoc also understands docstrings written in reStructuredText, Javadoc, and plaintext. Improvements in Version 3.0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Version 3.0 of epydoc adds support for extracting documentation information using both introspection (i.e., importing & inspecting the modules programmatically) and parsing (i.e., reading the source code of the modules); and for combining both sources of information. This is important because each source has its own advantages and disadvantages with respect to the other. See the epydoc FAQ for more information about the relative benefits of introspection and parsing, and why it's good to merge information from both sources: http://epydoc.sourceforge.net/faq.html#introspect_vs_parse Version 3.0 also adds the following features: * Support for variable docstrings. * Automatic generating of source code graphs, including class trees, package trees, uml class graphs, and import graphs. * Syntax highlighted source code, including links from identifiers back into the documentation. For more details about what's new in Epydoc 3.0, see: http://epydoc.sourceforge.net/whatsnew.html <P><A HREF="http://epydoc.sourceforge.net/">epydoc 3.0</A> - a tool for generating API documentation for Python modules, based on their docstrings.

ANN: shm and shm_wrapper 1.2
by Nikita the Spider Jan. 29, 2008

Jan. 29, 2008

Hi all, Versions 1.2 of shm and shm_wrapper -- two modules which enable IPC (shared memory and sempahores) via Python -- are now available. The former is Vladimir Marangozov's old shm module with some bug fixes, the latter is my wrapper which I find more Pythonic. Changes from version 1.1 include code that should enable shm to be used in conjunction with threads as well as setup and compilation improvements for various platforms. Enjoy! http://NikitaTheSpider.com/python/shm/ -- Philip http://NikitaTheSpider.com/ Whole-site HTML validation, link checking and more

Announcing the Python core sprint at PyCon 2008
by Brett Cannon Jan. 29, 2008

Jan. 29, 2008

As has occurred since the inception of PyCon, there will be a sprint on the Python core at this year's conference! If you will be attending PyCon (or will be in Chicago during the dates of the sprints), attending the sprint is a great way to give back to Python. Working on Python itself tends to deepens one knowledge of the language and the standard library. Plus it is just plain fun getting to sit around some tables with fellow Python programmers for several days (the sprint will last four days, but you do not need to attend all four days to participate). The sprint is open to everyone of all skill levels. We can always use help with things from updating documentation to preparing for the next release of Python 3.0. On Sunday evening of the conference there will not only be a sprint intro session, but also a tutorial on how to develop for Python. Details will be covered from where to look in the code base for things to some best practices tips. If you are interested enough to want to sign up to attend, please go to http://wiki.python.org/moin/PyCon2008/SprintSignups/Python and add your name and email address. If you have questions you may email me. Please sign up for the sprint by the end of February as an email on what you need to do beforehand will be sent at that time based on the sprint sign-up page. And if you are not attending PyCon, we will most likely have several people in attendance on IRC, thus allowing even people not at PyCon to participate! -Brett Cannon Python core sprint coach, PyCon 2008

Storm 0.12 is out!
by Gustavo Niemeyer Jan. 28, 2008

Jan. 28, 2008

On behalf of the Storm development team, I'm proud to announce that the release 0.12 is out! This is a very exciting release, as it brings several fixes and quite a few new features. Thank you very much to everyone who contributed. Storm is available at: https://storm.canonical.com Improvements ------------ - The Connection will reconnect automatically when connection drops are detected and a rollback is performed. As a result, the Store should handle reconnections in a seamless way in most circumstances (#94986, by James Henstridge). This is supported in the MySQL and PostgreSQL backends. - Store.flush() will not load values inserted in the database. Instead, undefined variables are set to AutoReload, and resolved once first accessed. This won't be noticeable in normal usage, but will boost the performance of inserts. - Support in the postgres backend to use the RETURNING extension of the INSERT statement to retrieve the primary key on inserts for object identity mapping (PostgreSQL >= 8.2 only) - Introduced a cache mechanism that keeps the N last retrieved objects in memory to optimize cases where the same object is retrieved often while no strong references are kept elsewhere. Implemented by Bernd Dorn, from Lovely Systems. - Improved support for TimeDelta properties on all backends. Many more formats are accepted now, and some issues were fixed. Bug fixes --------- - TimeDelta was added to storm.locals. - Fixed TimeDelta support in SQLite, MySQL, and PostgreSQL, and enabled base test for all backends to ensure that it continues to work. - Schema names are accepted in __storm_table__ when using PostgreSQL as the database (e.g. "schema.table"). (#146580, reported by James Mayfield) - Test runner handles path correctly on Windows, and SQLite tests won't break (patch by Ali Afshar). - In the SQLite backend, ensure that we're able to recommit a transaction after "database is locked" errors. Also make sure that when this happens the timeout is actually the expected one (patch by Richard Boulton) - TransactionFailedError is now imported from the public place: ZODB.POSException (#129715, by James Henstridge). - TimeDelta was added to storm.locals. - Tables named with reserved keywords are properly escaped. - Reserved keywords on column names are properly escaped when part of an insert or update statement (#184849, by Thomas Herve). - Prevent cached objects from issuing selects to retrieve their data when find()s were previously made and already brough their data (#174388, reported and fixed by Bernd Dorn). - Fixed bug which caused an object to be readded to the store when a reference of an object that had already been removed was looked up. - Prevent pathological case which happens when a statement like "SELECT ... WHERE table.id = currval(...)" is executed in PostgreSQL. The change is only meaningful on PostgreSQL < 8.2, as newer versions will use the RETURNING extension instead. - Specify both of the joining tables explicitly when compiling Proxy, so that it doesn't break due to incorrect references in the ON clause when multiple tables are used (reported in #162528 by S3ym0ur and Hamilton Tran) - MySQL client charset now defaults to UTF-8 (reported by Brad Crittenden). -- Gustavo Niemeyer http://niemeyer.net
