From paul at boddie.org.uk Sun May 1 23:44:46 2005 From: paul at boddie.org.uk (Paul Boddie) Date: 1 May 2005 14:44:46 -0700 Subject: WebStack 0.9 Message-ID: <1114983886.704882.267550@o13g2000cwo.googlegroups.com> Announcing release 0.9 of WebStack - a common API for Python Web applications. Applications written using the WebStack API can be deployed on the following servers and frameworks: BaseHTTPRequestHandler, CGI, Jython/Java Servlet API, mod_python, Twisted, Webware, WSGI and Zope 2. It should therefore be possible to develop applications and to run them with a single command using Python's standard library server modules, then to deploy them alongside other applications in more sophisticated environments when this becomes necessary or desirable. The PyPI entry for WebStack is here: http://www.python.org/pypi?%3Aaction=search&name=WebStack The public Web page for WebStack is here: http://www.boddie.org.uk/python/WebStack.html Since the last release, some introductory documentation has been added and some general improvements made to the stability and quality of the package. Have fun!

It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. 0.7.12 is a bug fix release: - handle capitalisation of class names in text hyperlinking (sf bug 1101043) - quote full-text search text in URL generation - fixed problem migrating mysql databases - fix search_checkboxes macro (sf patch 1113828) - fix bug in date editing in Metakit - allow suppression of search_text in indexargs_form (sf bug 1101548) - hack to fix some anydbm export problems (sf bug 1081454) - ignore AutoReply messages (sf patch 1085051) - fix ZRoundup syntax error (sf bug 1122335) - fix RDBMS clear() so it resets all class itemid counters If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.1.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: python demo.py Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.1+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and seven database back-ends (anydbm, bsddb, bsddb3, sqlite, metakit, mysql and postgresql).

With this release support for systems with limited CPU power and bandwidth (like PDA, mobile phones and hand-held devices) is introduced. Some bugs were fixed and now it's possible to search for "adult" titles. A GUI for Symbian Series 60 smart phones, developed by Tero Saarni, is available at http://kotisivu.mtv3.fi/terosaarni/python/imdbpygui/ IMDbPY aims to provide an easy way to access the IMDb's database using a Python script. Platform-independent and written in pure Python, it's independent from the data source (since IMDb provides two or three different interfaces to their database). IMDbPY is mainly intended for programmers and developers who want to build their Python programs using the IMDbPY package, but some example scripts - useful for the end users - are included. Other IMDbPY-based programs are available from the home page. -- Davide Alberani [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/ From frank at niessink.com Mon May 2 23:54:59 2005 From: frank at niessink.com (Frank Niessink) Date: Mon, 02 May 2005 23:54:59 +0200 Subject: [ANN] Release 0.35 of Task Coach Message-ID: <4276A1B3.1080805@niessink.com> Hi all, I'm pleased to announce release 0.35 of Task Coach. New in this release: Bugs fixed: * Toolbar icons had a black background instead of a transparent background on some Windows platforms (1190230). * Package i18n was missing (1190967). Features added: * Internationalization support. Task Coach is available with Dutch and English user interface (1164461). * Added 'expand selected task' and 'collapse selected task' menu items to the view menu and the task context menu (1189978). Features removed: * 'Select' -> 'Completed tasks'. This can be done through the View menu too. 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.

Pytest is a testing interpreter for Python. Unlike a testing /framework/, pytest requires nothing of its test scripts that is not included in the Python language itself. Pytests are regular Python scripts that are interpreted in a special way. Specifically, all explicit comparison statements (i.e., those with a comparison operator), are interpreted as tests, and their results are tallied and reported on following execution of the script. Documentation and downloads are available at: http://www.zetadev.com/software/pytest/ This initial release, version 0.3.0, is a development release. It will be of interest to those with a special interest in testing under Python, but will have bugs that may frustrate general users. Pytest is released under the following license: (c) 2005 Chad Whitacre This program is beerware. If you like it, buy me a beer someday. No warranty is expressed or implied. Thank you.

Written and optimized from the ground up to complement mod_python, as well as WSGI, CGI and application embedded environments, its conceptual design and template syntax is derived from HTML::Mason, the most widely used web application platform in the mod_perl world. It is designed with both the migrating Mason user and the original Python user in mind, supporting not just the full featureset of Mason, including a fully componentized development paradigm, page inheritance, autohandlers, dhandlers, component caching, friendly exception handling, etc. but also many Pythonic and environment-agnostic enhancements including full Python whitespace support within templates, a "module component"-based controller paradigm (compare to Servlets), a fully customizable rule-based URI resolver, full support and helper methods for multithreaded environments, component-specific flags for buffering, caching and whitespace trimming, environment-agnostic session support, full support for WSGI, an out-of-the-box demonstration runner, and a streamlined design taking full advantage of Python's unique architectural features. Version 0.97 brings higher-scaling memory management features, a new resolver strategy paradigm allowing full control of URI resolution and caching, fully customizable error handling, multiple character encoding support, and a new AJAX toolkit example illustrating seamless integration of Python functions and Myghty Methods with javascript. Since its last comp.lang.python.announce announcement in October 2004, Myghty has gained a fair userbase in its first nine months which is growing at a fast pace, being used on a handful of commercial and non-commercial sites. It receives favorable reviews for its ease of use, small footprint, quick and smooth operation, and great flexibility. Myghty is released under the GNU Lesser General Public License (LGPL).

Fred Pacquier alertly pointed out a bug I introduced in the last version. It occurs when you select all records in a table; newline characters were not getting stripped off the end of every returned record. The bug has been fixed in this version. Thanks Fred! KirbyBase is a simple, plain-text, database management system written in Python. It can be used either embedded in a python script or in a client/server, multi-user mode. You use python code to express your queries instead of having to use another language such as SQL. KirbyBase is disk-based, not memory-based. Database changes are immediately written to disk.

CherryPy-2 is a pythonic, object-oriented web development framework. CherryPy-2 is a redesign of CherryPy-1 (the unpythonic features have been removed): no more compilation step, pure python source code (no more "CherryClass"). Here is a sample Hello, World in CherryPy-2: # from cherrypy import cpg # class HelloWorld: # @cpg.expose # def index(self): # return "Hello world!" # cpg.root = HelloWorld() # cpg.server.start() Main properties: - this code starts a multi-threaded HTTP server that dispatches requests to methods - requests like "http://domain/dir/page?arg1=val1&arg2=val2" are mapped to "dir.page(arg1='val1', arg2='val2')" - CherryPy also supports "positional" arguments in URLs like http://domain/book/science/9 - requests are mapped to an object tree that is "mounted" on cpg.root (for instance: "cpg.root.user", "cpg.root.user.remi", ...) - method must be explicitely exposed with a decorator "@cpg.expose" (or "index.exposed = True" for Python-2.3) - methods can return a generator instead of a string (useful when generating big pages) Here is a non-exhaustive list of CherryPy-2 features: multi-threaded HTTP server, XML-RPC server, sessions, form handling, authentication, unicode support, gzip-compression, virtual hosting, WSGI adapter The design of CherryPy-2 allows to easily write/use pluggable "filters" or "modules": - filters perform operations on the request/response such as gzip-compression or string encoding - modules are web applications (like a blog or a web forum) than can be easily "mounted" anywhere you want in your website CherryPy-2 is already used in production by many sites and is supported by an active community.

Spyce is a python web application server, combining the features of popular frameworks such as JSP and ASP.NET with Pythonic elegance. Spyce may be deployed as a standalone server (or proxied behind Apache), or under mod_python, FastCGI, or CGI. Documentation and demos are at http://spyce.sourceforge.net/. Highlights of Spyce 2.0 include: Active Handlers - reusable components without the leaky abstractions seen in ASP.NET et al. - http://spyce.sourceforge.net/docs/doc-lang_handlers.html Active Tag compiler - http://spyce.sourceforge.net/docs/doc-tag_new2.html OpenACS-like (Tiles-ish, for you JSP people) parent/child templating system - roughly the same speed as include.spyce, so using one parent template has about 1/2 the overhead as the old standard two-includes-for-header-and-footer. - http://spyce.sourceforge.net/docs/doc-tag_core.html#parent Full changelog at http://svn-hosting.com/svn/spyce/trunk/spyce/CHANGES. -Jonathan From jacob at cd.chalmers.se Thu May 5 11:03:41 2005 From: jacob at cd.chalmers.se (Jacob Hallen) Date: 5 May 2005 09:03:41 GMT Subject: Europython update Message-ID: This is a news update about the Europython 2005 conference, to be held in Göteborg, Sweden 27-29 June - Due to some technical prolems with the registration website we have decided to extend the registration of talks until 8 May.

PuLP is an LP modeler written in python. PuLP can generate MPS or LP files and call GLPK[1], COIN CLP/SBB[2], CPLEX[3] and XPRESS[4] to solve linear problems. PuLP provides a nice syntax for the creation of linear problems, and a simple way to call the solvers to perform the optimization. See the example below. This version adds C modules to use the GLPK, COIN and CPLEX solvers without using intermediate MPS or LP files. It is faster and more reliable.

New in this release: Bug fixed: - Descriptions loose newlines after reload (1194259). Feature added: - French user interface added, thanks to Jerome Laheurte. 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.

SC-Corporate-ID is a commercial Smart Card security system that can be extended by the user using the Python language. SC-Corporate-ID is written in Python and wxPython for the most part (except for the PCSC wrapper, the GINA dll and the crypto) on the PC side, and in .... other languages on the Smart Card side. The PCSC driver (PYCSC) and the crypto (PYCRYPTO) are public domain packages (PYCSC was slightly modified by us) SC-Corporate-ID is an off-the shelf package: you can use it as is; yet, as it is based on a set of libraries (SCF), it can be modified and customized by the company using it (the restriction being the capabilities of the code in the Smart Card which would have to be modified by us). SC-Corporate-ID can be used for PC Access, Data Security (file encryption/signature), Company Electronic Purse and Corporate Identification. Some of its possible extentions are Building Access and WEB Security. SC-Corporate-ID cards can be delivered pre-programmed (firwmare + data) or simply with the firmware so the user may handle its own cards issuance. Although it is a commercial product, SC-Corporate-ID intends to be a true low cost security solution for Corporations. SC-Corporate-ID will soon be followed by a School/University ID as well as an Health Card ID. You may find information on SC-Corporate-ID at www.snakecard.com.

The API is 98 % stable now. And pysqlite itself should be a lot more stable too, now. The most notable changes are a lot of fixed refcount bugs, and the added documentation. Download the release here: Sources: http://initd.org/pub/software/pysqlite/releases/2.0/2.0.beta1/pysqlite-2.0.beta1.tar.gz win32 binaries for Python 2.3: http://initd.org/pub/software/pysqlite/releases/2.0/2.0.beta1/pysqlite-2.0.beta1.win32-py2.3.exe win32 binaries for Python 2.4: http://initd.org/pub/software/pysqlite/releases/2.0/2.0.beta1/pysqlite-2.0.beta1.win32-py2.4.exe pysqlite homepage, bug tracker, wiki: http://pysqlite.org/ Changes since 2.0.alpha4: ========================= - Added pysqlite 2.0 documentation: usage guide and source installation guide. Adapted from kinterbasdb documentation with the permission of David Rushby. - Fixed several refcount problems. Per test suite run, lose 0 references instead of 550 per test suite run like in alpha4. - If a database file cannot be opened, raise an OperationalError specifically instead of a DatabaseError. - Call the row factory with (cursor, row_tuple) instead of (row_tuple). - Fixed a crash in .connect() when you tried to set a keyword argument. It's quite annoying that Python doesn't offer a method to extract a single keyword argument at C-level easily. Argh! So I bit the bullet and duplicated the parameter extraction code. - The type name of PrepareProtocol was corrected. Only interesting for introspection. - Added more tests to the test suite. - Implemented cursor.arraysize. - cursor.rowcount is now -1 instead of None in case of "not determined", like the DB-API requires. - Implemented autocommit mode which replaces the ''no_implicit_begin'' parameter to the module-level connect(). This way, we're more compatible with other DB-API modules. autocommit parameter in module-level connect and also an autocommit property of connections. -- The "begin" method of connections is gone. - Completely reworked the advanced type detection: o connection.register_converter is gone o instead, the dictionary connection.converters is exposed directly. o The parameter more_types to the module-level connect is gone. o Instead, use any combination of PARSE_DECLTYPES and PARSE_COLNAMES for the new paramter detect_types. PARSE_DECLTYPES will parse out the first word of a declared type and look up a converter in connection.converters: create table foo(col mytype not null) The decltype would be "mytype not null", but PARSE_DECLTYPES will cut out "mytype" and look for a converter in converters["mytype"]. If it finds any, it will use it to convert the value. Otherwise, the standard SQLite manifest typing will be used. PARSE_COLNAMES will parse out the column names and look up a converter in connection.converters: cur.execute("select 1 as "colname [mytype]") the column names will be parsed for [...], in this case mytype will be found as the type for the colum, and the converters dictionary will be consulted for an appropriate converter function. If none is found, the standard SQLite manifest typing will be used. Also, the column names in cursor.description will only consist of the first word. So it would be "colname" in our example, not "colname [mytype]". - cursor.coltypes is gone. - The connection attribute of cursors is now made available at Python level. That's an optional DB-API extension. - The exception classes are now attributes of the connection objects. That's an optional DB-API extension. - Optimized the _sqlite_step_with_busyhandler() function by making time.time() and time.sleep() available at module import instead of importing the "time" module each time and getting out the "time" and "sleep" functions each time. Big performance improvement. - Some work on the benchmarks. - Made the destructor of the Cursor class more stable. It used to crash when an error occured in the Cursor *constructor*. - Implemented a check that the parameter for Cursor() is actually an instance of the Connection class (or a subclass thereof). - Allow long integers as parameters. Re-enable test cases for this. -- Gerhard H?ring - gh at ghaering.de - Python, web & database development pysqlite - Powerful and fast embedded database engine "SQLite" for Python. -------------- next part -------------- A non-text attachment was scrubbed...

The query is expressed either as a rough sketch painted by the user or as another image you supply (or an image in your collection). You may also do slideshows, generate web photo albums, edit image metadata including EXIF and IPTC data, organize images into a keyword hierarchy, and more. Changes ------- * fixes bug at startup on new versions of PyQT (QSizePolicy) * fixes bug at startup when detecting locale * Applied patch by Daniel Fahlgren. Fixes bug which made compared image (when loaded from an external file) to be loaded rotated. * implemented a "low level" jpeg loader, which interacts directly with libjpeg so now imgSeek doesn't have to read the whole jpeg file in order to generate thumbnails and add an image to database. That represents a reduction by 1/3 to the time needed to thumbnail and add images to the database. On some benchmarks, adding 160 files (1600x1200) would take an average of 1'10" and now it takes 32". * fixed bug on Windows where dialogs wouldn't show up again after being closed * fixed some unicode bugs * added "Rename image" menu option * finished Portuguese (BR) translation * added i18n support Requires -------- - Python 2.2.x, QT 3.x and PyQT 3.5. (3.4 should work) - ImageMagick development files or QT development files. Recommended: - Python Imaging Library.

You can download it from: http://www.zope.org/Members/Brian/PythonNet Highlights of this release: - Implemented a workaround for the fact that exceptions cannot be new-style classes in the CPython interpreter. Managed exceptions can now be raised and caught naturally from Python - Implemented support for invoking methods with out and ref parameters. Because there is no real equivalent to these in Python, methods that have out or ref parameters will return a tuple. The tuple will contain the result of the method as its first item, followed by out parameter values in the order of their declaration in the method signature. - Fixed a refcount problem that caused a crash when CLR was imported in an existing installed Python interpreter. - Added an automatic conversion from Python strings to byte[]. This makes it easier to pass byte[] data to managed methods (or set properties, etc.) as a Python string without having to write explicit conversion code. Also works for sbyte arrays. Note that byte and sbyte arrays returned from managed methods or obtained from properties or fields do *not* get converted to Python strings - they remain instances of Byte[] or SByte[]. - Added conversion of generic Python sequences to object arrays when appropriate (thanks to Mackenzie Straight for the patch). - Added a bit of cautionary documentation for embedders, focused on correct handling of the Python global interpreter lock from managed code for code that calls into Python. - PyObject.FromManagedObject now correctly returns the Python None object if the input is a null reference. Also added a new AsManagedObject method to PyObject, making it easier to convert a Python-wrapped managed object to the real managed object. - Created a simple installer for windows platforms. All known bugs have also been fixed - thanks to all who have sent in issue reports and patches for past releases. At this point, the only thing I plan to do before a 1.0 final is fix any new issues and add to the documentation (probably including a few specific examples of embedding Python for .NET in a .NET application).

It's an early release - lot's more features still to be added - but it all works. *Hurrah* rest2web is a tool for autogenerating websites. It allows you to store your contents in reST format, and generate pages and indexes from templates. It uses a simple but flexible templating system and generates index pages and navigation links. This means that adding new pages is as easy as dropping a text file into the right folder. rest2web will handle adding the link to the index page and creating the new page from a template and the contents. Removing a page is as easy as deleting a single file, and have rest2web automatically rebuild the indexes. The download includes the rest2web code, and docs, and a test site. The test site serves as a simple illustration of how rest2web builds pages and indexes. For full details see any of the following pages : * `rest2web Docs` - http://www.voidspace.org.uk/python/rest2web * `Example Site` - http://www.voidspace.org.uk/python/rest2web/test_site * `Quick Download (608k)` - http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=rest2web.zip The next features to add will be auto sitemap generation and a bigger change (under the hood) to make the index data available to every page in a section. This will allow pages to have sidebars with links, rather than just a single index page per section. I'm already building part of the Voidspace website with rest2web, over the next few months it will take over.... Lots of other features, tested on Linux and Windoze.

The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.6/pygtk-2.6.2.tar.gz Changes since 2.6.1: - Allow None to be sent in to set_group radio widgets (Johan, Lorenzo) - guint/gsize as longs (Gustavo) - Check for exceptions in child_watch (Mark McLoughlin) - Bug fixes (Johan, Manish Singh, John Finaly, Ulrik Svensson) Blurb: GTK is a toolkit for developing graphical applications that run on POSIX systems such as Linux, Windows and MacOS X (provided that the X server for MacOS X has been installed). It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full features applications. PyGTK requires GTK+ >= 2.6 and Python >= 2.3 to build. Bug reports, as always, should go to Bugzilla; check out http://pygtk.org/developer.html and http://pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK. -- Johan Dahlin johan at gnome.org From ianb at colorstudy.com Tue May 10 02:44:50 2005 From: ianb at colorstudy.com (Ian Bicking) Date: Mon, 09 May 2005 19:44:50 -0500 Subject: Topic - Tutorial: Web programming in Python with Paste Message-ID: <42800402.2070904@colorstudy.com> Topic - Tutorial: Web programming in Python with Paste ------------------------------------------------------ This month Ian Bicking will be presenting a tutorial Python web programming, using several different systems: Python Paste, Webware/WebKit, Zope Page Templates (not just for Zope!), and SQLObject. The technology covered will be similar to those presented in the To-Do tutorial. Except it will be live and in person.

Solipsis is a peer-to-peer system for a massively multi-participant virtual world. Like any real pear-to-pear system, there is no server at all: it only relies on end-users' machines. Overview -------- The shared virtual worlds of nowadays MMORPG strongly rely on privately owned servers. These servers are an expensive bottleneck that limits their scalability. In addition, these servers bound the freedom of the virtual world inhabitants and the imagination of the world-builders and developers. Solipsis solves these problems with a free and open-source system. Solipsis is a public virtual territory. The world is initially empty and only users will fill it by creating and running entities. No pre-existing cities, habitants nor scenario to respect... Solipsis is open-source, so everybody can enhance the protocols and the algorithms. Moreover, the system architecture clearly separates the different tasks, so that peer-to-peer hackers as well as multimedia geeks can find a good place to have fun here! Getting the software -------------------- The current version is 0.8.1, available as a tar.gz and as a windows installer http://solipsis.netofpeers.net/wiki/DownLoad Official Web site ----------------- http://solipsis.netofpeers.net/wiki/HomePage Requirements ------------ Current implementations of node and navigator require: * python?(at least 2.3) * wx-python?(at least 2.5) * twisted?

On this release you will find a series of exciting new features, being the most important the Undo/Redo capabilities, support for objects (and indexes!) with more than 2**31 rows, better I/O performance for Numeric objects, new time datatypes (useful for time-stamping fields), support for Octave HDF5 files and improved support for HDF5 native files. What it is ========== **PyTables** is a package for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data (with support for full 64-bit file addressing). It features an object-oriented interface that, combined with C extensions for the performance-critical parts of the code, makes it a very easy-to-use tool for high performance data storage and retrieval. It is built on top of the HDF5 library and the numarray package, and provides containers for both heterogeneous data (``Table``) and homogeneous data (``Array``, ``EArray``) as well as containers for keeping lists of objects of variable length (like Unicode strings or general Python objects) in a very efficient way (``VLArray``). It also sports a series of filters allowing you to compress your data on-the-fly by using different compressors and compression enablers. But perhaps the more interesting features are its powerful browsing and searching capabilities that allow you to perform data selections over heterogeneous datasets exceeding gigabytes of data in just tenths of second. Besides, the PyTables I/O is buffered, implemented in C and carefully tuned so that you can reach much better performance with PyTables than with your own home-grown wrappings to the HDF5 library. Changes more in depth ===================== Improvements: - New Undo/Redo feature (i.e. integrated support for undoing and/or redoing actions). This functionality lets you to put marks in specific places of your data operations, so that you can make your HDF5 file pop back (undo) to a specific mark (for example for inspecting how your data looked at that point). You can also go forward to a more recent marker (redo). You can even do jumps to the marker you want using just one instruction. - Reading Numeric objects from ``*Array`` and ``Table`` (Numeric columns) objects have a 50-100x speedup. With that, Louis Wicker reported that a speed of 350 MB/s can be achieved with Numeric objects (on a SGI Altix with a Raid 5 disk array) while with numarrays, this speed approaches 900 MB/s. This improvement has been possible mainly due to a nice recipe from Todd Miller. Thanks Todd! - With PyTables 1.0 you can finally create Tables, EArrays and VLArrays with more than 2**31 (~ 2 thousand millions) rows, as well as retrieve them. Before PyTables 1.0, retrieving data on these beasts was not well supported, in part due to limitations in some slicing functions in Python (that rely on 32-bit adressing). So, we have made the necessary modifications in these functions to support 64-bit indexes and integrated them into PyTables. As a result, our tests shows that this feature works just fine. - As a consequence of the above, you can now index columns of tables with more than 2**31 rows. For instance, indexes have been created for integer columns with 10**10 (yeah, 10 thousand million) rows in less than 1 hour using an Opteron @ 1.6 GHz system (~ 1 hour and half with a Xeon Intel32 @ 2.5 GHz platform). Enjoy! - Now PyTables supports the native HDF5 time types, both 32-bit signed integer and 64-bit fixed point timestamps. They are mapped to ``Int32`` and ``Float64`` values for easy manipulation. See the documentation for the ``Time32Col`` and ``Time64Col`` classes. - Massive internal reorganization of the methods that deal with the hierarchy. Hopefully, that will enable a better understanding of the code for anybody wanting to add/modify features. - The opening and copying of files with large number of objects has been made faster by correcting a typo in ``Table._open()``. Thanks to Ashley Walsh for sending a patch for this. - Now, one can modify rank-0 (scalar) ``EArray`` datasets. Thanks to Norbert Nemec for providing a patch for this. - You are allowed from this version on to add non-valid natural naming names as node or attribute names. A warning is issued to warn (but not forbid) you in such a case. Of course, you have to use the ``getattr()`` function so as to access such invalid natural names. - The indexes of ``Table`` and ``*Array`` datasets can be of long type besides of integer type. However, indexes in slices are still restricted to regular integer type. - The concept of ``READ_ONLY`` system attributes has disappeared. You can change them now at your own risk! However, you still cannot remove or rename system attributes. - Now, one can do reads in-between write loops using ``table.row`` instances. This is thanks to a decoupling in I/O buffering: now there is a buffer for reading and other for writing, so that no collisions take place anymore. Fixes #1186892. - Support for Octave HDF5 output format. Even complex arrays are supported. Thanks to Edward C. Jones for reporting this format. Backward-incompatible changes: - The format of indexes has been changed and indexes in files created with PyTables pre-1.0 versions are ignored now. However, ``ptrepack`` can still save your life because it is able to convert your old files into the new indexing format. Also, if you copy the affected tables to other locations (by using ``Leaf.copy()``), it will regenerate your indexes with the new format for you. - The API has changed a little bit (nothing serious) for some methods. See ``RELEASE-NOTES.txt`` for more details. Bug fixes: - Added partial support for native HDF5 chunked datasets. They can be read now, and even extended, but only along the first extensible dimension. This limitation may be removed when multiple extensible dimensions are supported in PyTables. - Formerly, when the name of a column in a table was subsumed in another column name, PyTables crashed while retrieving information of the former column. That has been fixed. - A bug prevented the use of indexed columns of tables that were in other hierarchical level than root. This is solved now. - When a ``Group`` was renamed you were not able to modify its attributes. This has been fixed. - When whether ``Table.modifyColumns()`` or ``Table.modifyRows()`` were called, a subsequent call to ``Table.flush()`` didn't really flush the modified data to disk. This works as intended now. - Fixed some issues when iterating over ``*Array`` objects using the ``List`` or ``Tuple`` flavor. Important note for Python 2.4 and Windows users =============================================== If you are willing to use PyTables with Python 2.4 in Windows platforms, you will need to get the HDF5 library compiled for MSVC 7.1, aka .NET 2003. It can be found at: ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/bin/windows/5-164-win-net.ZIP Users of Python 2.3 on Windows will have to download the version of HDF5 compiled with MSVC 6.0 available in: ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/bin/windows/5-164-win.ZIP Where can PyTables be applied? ============================== PyTables is not designed to work as a relational database competitor, but rather as a teammate. If you want to work with large datasets of multidimensional data (for example, for multidimensional analysis), or just provide a categorized structure for some portions of your cluttered RDBS, then give PyTables a try. It works well for storing data from data acquisition systems (DAS), simulation software, network data monitoring systems (for example, traffic measurements of IP packets on routers), very large XML files, or for creating a centralized repository for system logs, to name only a few possible uses. What is a table? ================ A table is defined as a collection of records whose values are stored in fixed-length fields. All records have the same structure and all values in each field have the same data type. The terms "fixed-length" and "strict data types" seem to be quite a strange requirement for a language like Python that supports dynamic data types, but they serve a useful function if the goal is to save very large quantities of data (such as is generated by many scientific applications, for example) in an efficient manner that reduces demand on CPU time and I/O resources. What is HDF5? ============= For those people who know nothing about HDF5, it is a general purpose library and file format for storing scientific data made at NCSA. HDF5 can store two primary objects: datasets and groups. A dataset is essentially a multidimensional array of data elements, and a group is a structure for organizing objects in an HDF5 file. Using these two basic constructs, one can create and store almost any kind of scientific data structure, such as images, arrays of vectors, and structured and unstructured grids. You can also mix and match them in HDF5 files according to your needs. Platforms ========= We are using Linux on top of Intel32 as the main development platform, but PyTables should be easy to compile/install on other UNIX machines. This package has also been successfully compiled and tested on a FreeBSD 5.4 with Opteron64 processors, a UltraSparc platform with Solaris 7 and Solaris 8, a SGI Origin3000 with Itanium processors running IRIX 6.5 (using the gcc compiler), Microsoft Windows and MacOSX (10.2 although 10.3 should work fine as well). In particular, it has been thoroughly tested on 64-bit platforms, like Linux-64 on top of an Intel Itanium, AMD Opteron (in 64-bit mode) or PowerPC G5 (in 64-bit mode) where all the tests pass successfully. Regarding Windows platforms, PyTables has been tested with Windows 2000 and Windows XP (using the Microsoft Visual C compiler), but it should also work with other flavors as well.

What's New ---------- * PyDO2 is now in the PyDO2 package, to facilitate peaceful coexistence with PyDO1. * explicit schema support (as in 'myschema.mytable'). * The "table" attribute can now be left out if the class name is the name of the table. * "refetch" behavior has been refactored. * there are a bunch of classes to help in doing various kinds of joins. What it is ---------- PyDO is Drew Csillag's ORM (Object-Relational Mapper) database access library for Python that facilitates writing a Python database access layer. PyDO attempts to be simple, flexible, extensible, and unconstraining. PyDO 2 is a rewrite of the 1.x series distributed with SkunkWeb. It has several enhancements: * PyDO can now be used in multi-threaded or twisted-style asynchronous sitations, with or without a customizable connection pool. * PyDO objects are now dict subclasses, but also support attribute access to fields. * Projections -- subsets of the field list of a super-class -- are now supported by the PyDO.project() method. * Table attributes are now declared in a more concise way. * Overall, the API has been tightened and the code restructured. It also has several limitations: * PyDO 2 is alpha code. Bugs should be expected, and the API is not guaranteed to be stable. * Currently, PyDO 2 supports fewer database systems than PyDO 1 (PostgreSQL, SQLite, and MySQL), although adding new drivers should not be difficult. * PyDO 2 requires Python 2.4 or later. PyDO is dual GPL/BSD licensed. The source tarball is available at SkunkWeb's berlios site: https://developer.berlios.de/projects/skunkweb/ or, more directly: http://download.berlios.de/skunkweb/PyDO-2.0a1.tar.gz Questions pertaining to PyDO can be addressed to the SkunkWeb mailing list at sourceforge: http://lists.sourceforge.net/lists/listinfo/skunkweb-list Cheers, js -- Jacob Smullyan From bud at comune.grosseto.it Tue May 10 19:04:56 2005 From: bud at comune.grosseto.it (Bud P.

SC-Corporate-ID is a commercial Smart Card security system that can be extended by the user using the Python language. SC-Corporate-ID is written in Python and wxPython for the most part (except for the PCSC wrapper, the GINA dll and the crypto) on the PC side, and in .... other languages on the Smart Card side. The PCSC driver (PYCSC) and the crypto (PYCRYPTO) are public domain packages (PYCSC was slightly modified by us) SC-Corporate-ID is an off-the shelf package: you can use it as is; yet, as it is based on a set of libraries (SCF), it can be modified and customized by the company using it (the restriction being the capabilities of the code in the Smart Card which would have to be modified by us). SC-Corporate-ID can be used for PC Access, Data Security (file encryption/signature), Company Electronic Purse and Corporate Identification. Some of its possible extentions are Building Access and WEB Security. SC-Corporate-ID cards can be delivered pre-programmed (firwmare + data) or simply with the firmware so the user may handle its own cards issuance. Although it is a commercial product, SC-Corporate-ID intends to be a true low cost security solution for Corporations. SC-Corporate-ID will soon be followed by a School/University ID as well as an Health Card ID. You may find information on SC-Corporate-ID at www.snakecard.com.

Many thanks to all the speakers who are putting their efforts into this. - A list of talks is now available,either through the "Track Overview" menu item on the Europython website, or directly at http://www.python-in-business.org/ep2005/atracks.chtml - Around the end of May we will be soliciting input from all attendees on what talks they aremost interested in. This information will be used in scheduling, in order to reduce the amounts of collisions between popular talks and in order to reduce the risk of overcrowding a small room with a talk that turns out to be very popular. - Early bird registrations end 15 May. Registration for the low cost accomodation close to the conference venue ends on the same day. We may have further accomodation available at a later date, but we can't make any promises. - Please help us become the biggest Python/Zope conference. Talk to your friends about Europython and write about the conference in your blog. The more people who show up, the more we can spend on getting the best and most interesting talks. - This year we have a special focus on Python newbies in the Tutorials track. If you have staff or customers who need a well rounded introduction to Python, send them to Europython 2005. For all conference details, go to: http://www.europython.org See you in Göteborg. EuroPython Team. About EuroPython: Europython is an annual conference for the Python and Zope communities. It circulates between different sites in Europe. Having started in Charleroi, Belgium, it is now in Göteborg, Sweden and will move to CERN in Swizerland next year. Europython is a community conference run by volunteers. -- From unicorn at kurskline.ru Thu May 12 11:52:10 2005 From: unicorn at kurskline.ru (Roman V.

New in this release: Bugs fixed: - Icons in tree view on Windows 2000 (1194654). I hope I fixed this, but since I have no access to Windows 2000 it's a bit difficult to test. Features added: - Columns in the task list view can be turned on/off by right-clicking on the column headers. - Tasks can be sorted either by due date or alphabetically (1177984). - More options when editing an effort record. - Used a new DatePickerCtrl (1191909). 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.

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 summer 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 at uniserve.com Beta 0.14: A number of bug fixes, many more system macros, ALLTRACKS command added, major fixes to chord generation.

Another problem is that you risk scheduling talks against each other that have a very large set of interested people in common. At Europython we are this year going to try a new way of scheduling, in order to reduce these problems. Before the schedule is made, we will give all attendees the opportunity to register what talks they are most interested in. We then want to make a schedule that is optimised based on these data. Since I am no expert in optimising algorithms of this type, and since the time I have available for these things is limited, I'm turning to the readers of c.l.p and python-logic for help. I'm offering the following bounty for a working solution (in Python): - Free attendance at this years Europython, as a guest of honour - A Europython T-shirt in a limited special edition - Fame and gratitude from conference attendees who get better scheduling The winner of the bounty is the person who scores most points, according to the criteria below. If we get more than one solution that does good optimisation, we will award more than one bounty. Here are the parameters: 1. There are 10 tracks with between 1 and 30 talks in each track. You may not schedule two talks in the same track against each other, unless there is more talks than available calendar time. 2. A track should be continuous. Each track that is continuous gives you 10 points. 3. We expect about 300 attendees. About half of them are expected to register their interests. Interests may range from a single talk to more than half of all the talks. You get one point for each talk an attendee can attend out of the ones the attendee has registered interest in. 4. Talks are of varying lengths. Lengths can be 30, 45, 60 and 90 minutes. The large majority of talks are 30 minutes. Only a very few are 45 minutes. 5. Rooms come in different sizes Room A has 180 seats Room B has 140 seats Room C has 140 seats Room D has 70 seats Room E has 70 seats Room A-D should be scheduled throughout the conference while room E is extra expansion space, only to be used when absolutely necessary. For every person scheduled above (Room capacity * (Number of responding attendees / Total number of attendees)) you get one point taken off your score. 6. There are a total of 10 90-minute time blocks. Day 1: 09:00 Day 1: 11:00 Day 1: 14:00 Day 1: 16:00 Day 2: 09:00 Day 2: 11:00 Day 2: 14:00 Day 2: 16:00 Day 3: 09:00 Day 3: 11:00 A track should not change room in the middle of a time block. Doing so reduces your score by 50 points. 7. Input data You get your input data in the form of a list of tuples; one tuple per talk. Each tuple looks like this: (, , , [list of interested attendees]) Talk length is an integer, all other items are strings. 8. Output data You should supply your output data in the form of a list of tuples; one tuple per talk. Each tuple should look like this: (, , , ) Talk id should be the same as in the input. Room should be a one letter string with a value in the range A-E. Day should be a one letter string in the range 1-3. Starting time should be a string on the form HH:MM, in the 24 hour clock. Solutions should be sent by email to europython at python.org no later than 1 June 2005. Currently we haven't started gathering real data, but there should be some available for real world testing before 1 June. -- From aahz at pythoncraft.com Mon May 16 07:18:25 2005 From: aahz at pythoncraft.com (Aahz) Date: Sun, 15 May 2005 22:18:25 -0700 Subject: BayPIGgies: May 19, 7:30pm (FIRST meeting at Google) Message-ID: <20050516051825.GA4426@panix.com> NOTE: we are no longer meeting at Stanford; the May meeting is at Google in Mountain View.

Message-ID: <20050516183006.GA4284@mylene.ghaering.de> Hello everyone, After pondering about a redesign of pysqlite for years, and now after half a year of development, I am happy to finally announce the first stable release of pysqlite2. pysqlite a DB-API 2.0-compliant database interface for SQLite. SQLite is a relational database management system contained in a relatively small C library. It is a public domain project created by D. Richard Hipp. Unlike the usual client-server paradigm, the SQLite engine is not a standalone process with which the program communicates, but is linked in and thus becomes an integral part of the program. The library implements most of SQL-92 standard, including transactions, triggers and most of complex queries. pysqlite makes this powerful embedded SQL engine available to Python programmers. It stays compatible with the Python database API specification 2.0 as much as possible, but also exposes most of SQLite's native API, so that it is for example possible to create user-defined SQL functions and aggregates in Python. If you need a relational database for your applications, or even small tools or helper scripts, pysqlite is often a good fit. It's easy to use, easy to deploy, and does not depend on any other Python libraries or platform libraries, except SQLite. SQLite itself is ported to most platforms you'd ever care about. It's often a good alternative to MySQL, the Microsoft JET engine or the MSDE, without having any of their license and deployment issues. pysqlite homepage: http://pysqlite.org/ On the homepage, there's also a bug tracking system and a wiki. Sources: http://initd.org/pub/software/pysqlite/releases/2.0/2.0.0/pysqlite-2.0.0.tar.gz Windows binaries for Python 2.3: http://initd.org/pub/software/pysqlite/releases/2.0/2.0.0/pysqlite-2.0.0.win32-py2.3.exe Windows binaries for Python 2.4: http://initd.org/pub/software/pysqlite/releases/2.0/2.0.0/pysqlite-2.0.0.win32-py2.4.exe Advantages of pysqlite 2.0 over pysqlite 1.x ============================================ - Straightforward: No surprises: pysqlite 2.0 does not convert any types behind your back. With default settings, it only supports the database types SQLite supports out of the box: INTEGER, REAL, TEXT, BLOB and NULL. - Documentation: pysqlite 2.0 now has usable documentation. The usage manual covers the full API. - Advanced type system: It is, however, possible to turn on type detection like in the old pysqlite. Types can be detected by their declared type in the "CREATE TABLE" statement. Or, for values that don't originate directly from tables or views, it's possible to detect the type from the column name via a neat trick. For details, look into the pysqlite usage manual. No more "-- types" hack like in the old pysqlite. Type conversion from Python to SQLite works via PEP-246-like object adaptation. - Fine-grained transaction control: pysqlite 2.0 allows to control which type of transactions are opened via the transaction_isolation property - None for auto-commit mode or one of SQLite's transaction types "DEFERRED", "IMMEDIATE", "EXCLUSIVE". - executemany() uses precompiled statements for optimal speed. - Result sets are not prefetched any more, rows are only fetched on demand. So, pysqlite 2.0 behaves a lot nicer with respect to memory usage. - pysqlite 2.0 supports both the "qmark" and "named" paramstyle. So you can supply query parameters as sequences or as mappings. - Performance: pysqlite 2.0 is almost entirely written in hand-coded C. Under most circumstances, it is noticeably faster than the old pysqlite. On the pysqlite wiki, there's a page with benchmarks: http://initd.org/tracker/pysqlite/wiki/PysqliteBenchmarks The benchmark shows that executemany() is 5 times as fast as in pysqlite 1.1. Open issues: ============ pysqlite 2.0 does currently not compile under MacOS X Tiger (10.2 seems to work for me on the SF compile farm), because of unresolved symbols. Unfortunately, I don't have access to that platform. I will need a patch with a real fix from a MacOS X users to fix the problem. And, for those who have followed the alpha/beta testing: Changes since pysqlite 2.0beta1 =============================== - Removed dead code. - Improved error handling. - Fixed a leak that occurred when erroneous SQL was sent to execute(many)(). - Recognize REPLACE as DML statement and start transactions appropriately. - Issue a Warning when users send more than one SQL statement to execute(many)(). - Changed a few mappings SQLite error => DB-API exception. - Added lots of new unit tests so all testable code paths are tested/executed. This was done when doing coverage testing using gcov. - Implemented a nonstandard convenience method cursor.executescript(sql) to execute several SQL statements in a bunch, for example for creating a database initially. - The converters dictionary was moved from the Connection object into the DB-API module. Register converters with register_converter(converter_name, callable). - the prepareProtocol parameter is gone. - instead, register adapters directly with register_adapter(type, adapter_callable) in the DB-API module. - check for closed connections - make sure it's impossible to destroy connections as long as there are still cursors using them - fixed a crash when a converter returned None - fixes to MANIFEST.in - default converters and adapters for date/date and datetime/timestamp - Replaced autocommit flag with isolation_level flag. This way, it's possible to use no transaction handling at all (autocommit), or control the types of transactions that are created (DEFERRED, IMMEDIATE, EXCLUSIVE). - thread_id is now long instead of int - so pysqlite compiles on 64-bit platforms, too. -- Gerhard H?ring - gh at ghaering.de - Python, web & database development -------------- next part -------------- A non-text attachment was scrubbed...

The documentations contains a (hopefully) nice collections of use cases (which are also test cases, sice I take doctest very seriously ;). You can find it here: http://www.phyast.pitt.edu/~micheles/python/decorator.zip It is released under the Python licence. Let me know if you are using it and if you would like further additions/improvements/changes/etc. Feeback is welcome!

Note that this is an implementation of Set class -- not BaseSet or ImmutableSet. For more information about the Set class, see the current Python documentation on that module: http://docs.python.org/lib/module-sets.html jyset currenly lacks some type checking -- for example, if you try to check to see if s2 is a superset of s1 and s2 is really an integer, you will get a more cryptic error. You have been warned (if someone would like to help with this . . ) See the main function of jyset.py or the sample.py for usage help, although the link to the Python Docs would probably be more helpful!
