Porcupine Web Application Server 0.0.4 released
by t.koutsovassilis＠gmail.com Sept. 25, 2005

Sept. 25, 2005

This release includes the latest QuiX build and also contains an enhanced version of the "pakager" utility. Furthermore, the previous versions required the data type's class name and the Porcupine object's attribute name to be identical; this limitation no longer exists. This release also takes care of those having installed the previous release (0.0.3) and wish to upgrade in a straightforward manner. Python, AJAX and XUL roaring under the same hood... For more info, see http://www.innoscript.org/content/view/34/2/ Enjoy.

Proboscis 0.1 Release
by James William Pye Sept. 25, 2005

Sept. 25, 2005

This is the first release announcement for Proboscis[1], the PQueue based Green Trunk implementation. It is a PostgreSQL driver/interface for Python. Another one? Well, yes and no. Proboscis is not libpq based, nor does it primarily produce a DB-API 2.0 interface(0.2 may include a layer for DB-API 2.0 users). The release news item can be found here[2]. This frontend features, in no particular order, the following: * Pure Python * Green Trunk interface * Thread safety * Windows support * Basic SSL support * COPY TO/FROM support * Protocol level prepared statements and cursors(Portals) * Demand based cursor activity * query and procedure methods (see Green Trunk documentation) * bytea transparency (hint: no need to escape when using parameters) * Wire Tap (asynchronous notifications) * Automatic client encoding/decoding Pure Python? It must be slow, no? Well, first, there is an optional C extension module to provide an optimization in one sensitive area, so it's not necessarily pure Python. As 1.0 approaches, other sensitive areas may be optimized as well. So how slow or fast is it? The following are some simple trials: (The server and the client are on the same machine) Copying, COPY FROM Summary, copied tuples: 50000 copied bytes: 2882981 duration: 2.186987 average tuple size(bytes): 57.000000 average KB per second: 1287.159045 average tuples per second: 22862.505244 COPY TO Summary, copied tuples: 50000 duration: 2.299819 average KB per second: 1224.009372 average tuples per second: 21740.841414 (Warning: Without the C extension module, COPY TO's TPS will be cut in half) Querying, INSERT Summary, inserted tuples: 1000 total time: 1.903957 average tuples per second: 525.221976 (Note: Mass INSERT will likely be ~2-3x faster in version 0.2) SELECT Summary, looped: 51 read tuples: 1000 looptime: 0.323199 time reading tuples: 0.322262 loop overhead: 0.000937 average tuples per second: 3103.064739 (Warning: Without the C extension module, SELECT will lose 1000TPS) While it is unlikely that these speeds will be seen in practice, it does give one an idea as to what this interface can do with simple data. For the quickest way to get started, see the Frontend sections of the Quick Start page[4]. For further help, sign-up and post questions to the mailing list[5].

[ANN] Release 0.48 of Task Coach
by Frank Niessink Sept. 24, 2005

Sept. 24, 2005

Hi all, Unfortunately, the previous release of Task Coach contained two nasty bugs. This release aims to fix those bugs: Bugs fixed: * Filtering tasks by status ('View' -> 'Tasks that are' -> '...') would cause an exception. * Sorting by days left would cause an exception. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://taskcoach.niessink.com https://sourceforge.net/projects/taskcoach/ A binary installer is available for Windows XP, in addition to the source distribution. Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

PyODB version 0.3 released
by Neil Moses Sept. 24, 2005

Sept. 24, 2005

I would like to announce version 0.5 of PyODB a Python unixODBC API binding. This release contains improvements to the mapping between the SQL and Python datatypes and a re-write of the data retrieval code. PyODB is a Python module and provides a simplified set of bindings to unixODBC (http://www.unixodbc.org) allowing fast and easy development of open database applications. The module supports multiple data source connections with the following connection methods; execute(), fetch(), disconnect(), begin(), commit() and rollback(). The software has been developed on a Linux environment using Python 2.x and SWIG (http://www.swig.org). The module has been tested on Linux and Solaris platforms using databases MySQL, Informix and PostgreSQL but in theory should work on any platform supporting unixODBC and an ODBC database driver. To download the release visit http://sourceforge.net/projects/pyodb Regards, Neil Moses

Present files for download and statistics (basic) about download rates. This update has a security fix and uses the pythonutils 0.2.2 set of modules. Also other minor updates. It also needs the updated version of cgiutils. cgiutils 0.3.3 http://www.voidspace.org.uk/python/recipebook.shtml#utils A helpful set of constants and functions when working with CGI scripts. This update has two bugfixes. copy2cgi 1.1.1 http://www.voidspace.org.uk/python/recipebook.shtml#copy2cgi A small convenience script to copy files and directories to a target location. Useful for copying files to a server directory for testing. pycrypto 2.0.1 http://www.voidspace.org.uk/python/modules.shtml#pycrypto I've (finally) updated the prebuild windows binary of PyCrypto (Python 2.4) to the 2.0.1 version. All the best, Fuzzyman http://www.voidspace.org.uk/python/weblog/index.shtml All the Voidspace modules and applications are available under the OSI Approved Open Source BSD License - http://www.voidspace.org.uk/python/license.shtml
