sednaobject - Pythonic interface to Sedna XML Database
by Jim Washington April 9, 2008

April 9, 2008

I've put out a new alpha (0.10alpha2) of zif.sedna, a Python adapter to Sedna, a multi-user XML database, at the Python Cheese Shop. The new alpha has a start at objectifying XML from the Sedna database in a manner kind of like sqlobject does for SQL. The aim is to make easy, pythonic CRUD (create, read, update, delete) operations for the XML store. Push data in, get data back out. sednaobject, now included in zif.sedna, provides three classes. First is SednaXQuery, which gives you list-like semantics for the results of any arbitrary XQuery or XPath expression. You init it with a Sedna cursor, a query statement, and an optional parser method. Then, you can iterate, or obtain items by index or slice. If you do not provide a parser, you get items as unicode strings. Second is SednaContainer, which behaves like a SednaXQuery, except it is read-write. Like SednaXQuery, you init it with a cursor, a query statement, and an optional parser method. The query statement must refer to exactly one element in the database. This is the container, and you can obtain and replace items in the container by index. Slicing works for retrieval, and append, remove, insert, and del work as per the elementtree API. Third is SednaObjectifiedElement, which also operates on a single element in the database. SednaObjectifiedElement is a thin wrapper around lxml.objectify. Alter the item with the objectify API, and save(). Thanks, lxml team, for making this really easy! Since, in XML, an element is an element is an element, you can use the second and third sednaobject classes on any element in the database. Which you would use in a situation depends on the aspect you are interested in at the moment. I see Sedna as an attractive middle ground between SQL databases and object databases like ZODB. Data size is practically unlimited. You can alter a small portion of a data set transactionally, in a multi-user environment, without a full rewrite of the data. Like SQL databases, it uses a query language to obtain and format just the data you want, from anywhere in the database. XQuery has nice built-in functionality for counting, filtering, reordering, doing math, etc., on items. Like ZODB, you can store and retrieve items of arbitrary complexity without too much fuss. A Sedna database can have multiple XML documents and multiple 'collections' of (similar) documents that can be queried together or separately. The Sedna team just released version 3.0 of the Sedna server, which has improved speed and reliability. 3.0 now runs on Mac OSX, in addition to x86 Linux and Win2K/XP. zif.sedna with sednaobject version 0.10 is alpha, so interfaces can and probably will change. The included doctests all pass using a Sedna 2.x server. I have not included the new features of 3.0 (e.g., faster, read-only queries) yet. Testing with a 3.0 server results in a single harmless failure. Speed? I'm getting 60-70 single-query transactions per second through Pylons on a 2Ghz Opteron. Transaction speed of course depends on how many queries are in the transaction and what the queries do. zif.sedna: http://pypi.python.org/pypi/zif.sedna/ Sedna: http://modis.ispras.ru/sedna/ I am currently the sole developer for zif.sedna. Feedback is welcome. - Jim Washington

Guppy-PE / Heapy 0.1.8
by Sverker Nilsson April 8, 2008

April 8, 2008

I am happy to announce Guppy-PE 0.1.8 Guppy-PE is a library and programming environment for Python, currently providing in particular the Heapy subsystem, which supports object and heap memory sizing, profiling and debugging. It also includes a prototypical specification language, the Guppy Specification Language (GSL), which can be used to formally specify aspects of Python programs and generate tests and documentation from a common source. The current version is updated to work in 64-bit mode and with Python-2.6, and still works in 32-bit mode and with Python 2.3, 2.4 and 2.5. No other major changes have been made from Guppy 0.1.6. In the nearest future, I plan to add interactive help and more examples to the documentation, perhaps a tutorial. Look out for this in the svn HEAD according to instructions at the project home page, if you want the latest version. I will try to make a new release in perhaps a month or so. License: MIT Guppy-PE 0.1.8 is available in source tarball format on the Python Package Index (a.k.a. Cheeseshop): http://pypi.python.org/pypi/guppy/0.1.8 The project homepage is on Sourceforge: http://guppy-pe.sourceforge.net Enjoy, Sverker
