ANN: Pyro 3.6 beta
by Irmen de Jong Feb. 12, 2007

Feb. 12, 2007

It is with great pleasure that I announce that the release of a beta version of Pyro 3.6-- the greatest Pyro release yet! "What is Pyro?" "Pyro is short for PYthon Remote Objects. It is an advanced and powerful Distributed Object Technology system written entirely in Python, that is designed to be very easy to use. Never worry about writing network communication code again." Go to Pyro's Sourceforge download page to get it, and please give it a good testing. It would be great to hear of any issues or problems you encounter, before putting out the final 3.6 release. Pyro has been a Sourceforge project for over 6 years now. http://pyro.sourceforge.net http://sourceforge.net/projects/pyro I have made a HUGE amount of improvements and fixes since the previous version, 3.5, which was released about 14 months ago (sorry!). If you want to review what has been done, read the 'changes' chapter in the manual, and/or visit Pyro's "todo" wiki page: http://www.razorvine.net/python/PyroTodoList Thanks for your support, and I'm looking forward to release a final Pyro-3.6 version soon ! Sincerely, --Irmen de Jong PS: Sourceforge's shell access is down at the moment so I can't update the Pyro web page itself yet.

by Nikita the Spider Feb. 12, 2007

Feb. 12, 2007

Hi all, Versions 1.1 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. Feedback is welcome. http://NikitaTheSpider.com/python/shm/ Enjoy! -- Philip http://NikitaTheSpider.com/ Whole-site HTML validation, link checking and more

SQLObject 0.8.0
by Oleg Broytmann Feb. 12, 2007

Feb. 12, 2007

Hello! I'm pleased to announce the 0.8.0 release of SQLObject. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.8.0 News and changes: http://sqlobject.org/News.html What's New ========== News since 0.7 -------------- Features & Interface -------------------- * It is now possible to create tables that reference each other. Constraints (in the DBMSes that support constraints) are added after the tables have been created. * Added ``createSQL`` as an option for sqlmeta. Here you can add related SQL you want executed by sqlobject-admin create after table creation. createSQL expects a string, list, or dictionary. If using a dictionary the key should be a dbName value (ex. 'postgres') and the value should be a string or list. Examples in sqlobject/tests/test_sqlobject_admin.py or at <http://sqlobject.org/sqlobject-admin.html#the-create-command> * Added method ``sqlhub.doInTransaction(callable, *args, **kwargs)``, to be used like:: sqlhub.doInTransaction(process_request, os.environ) This will run ``process_request(os.environ)``. The return value will be preserved. * Added method ``.getOne([default])`` to ``SelectResults`` (these are the objects returned by ``.select()`` and ``.selectBy()``). This returns a single object, when the query is expected to return only one object. The single argument is the value to return when zero results are found (more than one result is always an error). If no default is given, it is an error if no such object exists. * Added a WSGI middleware (in ``sqlobject.wsgi_middleware``) for configuring the database for the request. Also handles transactions. Available as ``egg:SQLObject`` in Paste Deploy configuration files. * New joins! ManyToMany and OneToMany; not fully documented yet, but still more sensible and smarter. * SELECT FOR UPDATE * New module dberrors.py - a hierarchy of exceptions. Translation of DB API module's exceptions to the new hierarchy is performed for SQLite and MySQL. * SQLiteConnection got a new keyword "factory" - a name or a reference to a factory function that returns a connection class; useful for implementing functions or aggregates. See test_select.py and test_sqlite_factory.py for examples. * SQLObject now disallows columns with names that collide with existing variables and methods, such as "_init", "expire", "set" and so on. Small Features -------------- * Configurable client character set (encoding) for MySQL. * Added a close option to .commit(), so you can close the transaction as you commit it. * DecimalValidator. * Added .expireAll() methods to sqlmeta and connection objects, to expire all instances in those cases. * String IDs. * FOREIGN KEY for MySQL. * Support for sqlite3 (a builtin module in Python 2.5). * SelectResults cannot be queried for truth value; in any case it was meaningless - the result was always True; now __nonzero__() raises NotImplementedError in case one tries bool(MyTable.select()) or "if MyTable.select():..." * With empty parameters AND() and OR() returns None. * Allows to use set/frozenset sets/Set/ImmutableSet sets as sequences passed to the IN operator. * ID columns are now INT UNSIGNED for MySQL. Bug Fixes --------- * Fixed problem with sqlite and threads; connections are no longer shared between threads for sqlite (except for :memory:). * The reference loop between SQLObject and SQLObjectState eliminated using weak references. * Another round of bugfixes for MySQL errors 2006 and 2013 (SERVER_GONE, SERVER_LOST). * Fixed a bug in MSSQLConnection caused by column names being unicode. * Fixed a bug in FirebirdConnection caused by column names having trailing spaces. * Order by several columns with inheritance. * Fixed aggregators and accumulators with inheritance. For a more complete list, please see the news: http://sqlobject.org/News.html Oleg. -- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

[ANN] Initial release of Throxy: throttling HTTP proxy in one Python file
by Johann C. Rocholl Feb. 11, 2007

Feb. 11, 2007

Throxy: throttling HTTP proxy in one Python file * Simulate a slow connection (like dial-up). * Adjustable bandwidth limit for download and upload. * Optionally dump HTTP headers and content for debugging. * Decompress gzip content encoding for debugging. * Multiple connections, without threads (uses asyncore). * Only one source file, written in pure Python. To use it, run throxy.py on your local machine and adjust your browser settings to use 127.0.0.1:8080 as HTTP proxy. Simulate analog modem connection: $ python throxy.py -u28.8 -d57.6 Show all HTTP headers (request & reply): $ python throxy.py -qrs Dump HTTP headers and content to a file, without size limits: $ python throxy.py -rsRS -l0 -L0 -g0 > dump.txt Tell command line tools to use the proxy: $ export http_proxy=127.0.0.1:8080 Command line options: --version show program's version number and exit -h, --help show this help message and exit -i <ip> listen on this interface only (default all) -p <port> listen on this port number (default 8080) -d <kbps> download bandwidth in kbps (default 28.8) -u <kbps> upload bandwidth in kbps (default 28.8) -o allow remote clients (WARNING: open proxy) -q don't show connect and disconnect messages -s dump headers sent to server -r dump headers received from server -S dump content sent to server -R dump content received from server -l <bytes> maximum length of dumped text content (default 1024) -L <bytes> maximum length of dumped binary content (default 256) -g <bytes> maximum size for gzip decompression (default 8192) Subversion repository (or simple download): http://svn.browsershots.org/trunk/throxy/throxy.py Pretty source code (and change history): http://trac.browsershots.org/browser/trunk/throxy/throxy.py This is a very early release. Please send feedback per email. Alternatively, you can file bugs and feature requests here: http://trac.browsershots.org/newticket?component=throxy Cheers, Johann

FlightFeather Social Networking Platform 0.3.3
by George Belotsky Feb. 10, 2007

Feb. 10, 2007

FlightFeather's goal is "social networking for everyone". This means that *anyone* should have a chance to run a *popular* social networking site -- on minimal hardware, and without wasting bandwidth. Version 0.3.3 is the current development release. It modifies the way the FlightFeather server loads the configuration, protocol, session, and storage modules on startup. The actual loading process now takes place after all options have been parsed. If the "-c" or "--command" option is present, the server does not import these modules at all, since they are not required. The new implementation also fixes a bug that caused the test versions of the above modules to always load, in addition to any modules specified on the command line. The current beta release of FlightFeather is 0.2.8. You can download these releases (free/open source under the GPL) from the "BoSStats" site, which runs on FlightFeather. http://www.bosstats.com/flightfeather.html You are always welcome to participate in the discussion on the "BoSStats" site; the topic covered (what makes a good boss, office politics, etc.) is valuable in and of itself. Please, however, refrain from posting test comments, as the site is live. A Brief Overview of FlightFeather and BoSStats ---------------------------------------------- You can see FlightFeather in action on the BoSStats site. BoSStats is dedicated to improving the world of work: you can discuss what makes a good boss, or share your experiences of office politics. You can also comment and vote on the posts made by others. The application does not set cookies, and no registration is required for anything except voting. http://www.bosstats.com/ BoSStats is a good testbed for FlightFeather, and has value of its own, since meaningful advice about work-related problems is very hard to find. A "Wisdom of Crowds" solution -- particularly with strong privacy protection (see below) -- is a necessary addition to this field. FlightFeather's most important feature is that all write requests generate (or modify) HTML files. In consequence, a pure read (the most common operation) merely serves static pages. The major design focus for FlightFeather are responsiveness and performance; the system should eventually support very high traffic volumes. In addition, FlightFeather allows for a great deal of user privacy -- a critical, rapidly emerging problem in the social networking realm.
