HTSQL 2.0 RC1 -- a Query Language for the Accidental Programmer
by Clark C. Evans 21 Jan '11

21 Jan '11

Kirill Simonov and myself would like to introduce HTSQL, a novel approach to relational database access which is neither an ORM nor raw SQL. HTSQL is a URI-based high-level query language for relational databases. It's implemented as a Python WSGI application. Currently it supports PostgreSQL and SQLite (more databases & juicy features forthcoming). Homepage: http://htsql.org Download: http://pypi.python.org/pypi/HTSQL/ Source: http://bitbucket.org/prometheus/htsql At this point, HTSQL 2.0 may not be mature enough for production use; we expect to fill in any remaining gaps in the coming months. We're curious what you think. Join us in #htsql on freenode [1], subscribe to the mailing list [2] and please come to our PyCon 2011 talk [3]. Clark & Kirill [1] irc://irc.freenode.net/#htsql [2] http://lists.htsql.org/mailman/listinfo/htsql-users [3] http://us.pycon.org/2011/schedule/sessions/264/

Sala 1.0 released
by Petri Lehtinen 21 Jan '11

21 Jan '11

I'm proud to announce the first release of sala, an encrypted plaintext password store. Sala is a command-line utility that lets you store passwords and other bits of sensitive plain-text information to encrypted files on a directory hierarchy. This makes it integrate nicely with the shell; tab completion works, for example. It's also convenient to store your passwords in version control, for example. The stored information is protected by GnuPG's symmetrical encryption. Sala has been written in Python. It requires gpg[1], the GnuPGInterface[2] library, and (with the default configuration) uses pwgen[3] to suggest good passwords, if it's installed. To install: pip install sala Docs & download: http://pypi.python.org/pypi/sala Git repository: http://github.com/akheron/sala Author: Petri Lehtinen, http://www.digip.org [1] http://www.gnupg.org/ [2] http://py-gnupg.sourceforge.net/ [3] http://sourceforge.net/projects/pwgen/

soaplib 2.0.0 beta1 released
by Chris Austin 21 Jan '11

21 Jan '11

Announcing soaplib 2.0.0 beta 1 We are pleased to announce 2.1.0-beta1 of soaplib. This introduces significant API changes since the 2.1.0-alpha released in Sept 2010. This release also marks the transition to new maintainers (Brad Allen and Chris Austin), and a new repository location indicated on the new PyPI record ( https://github.com/soaplib/soaplib). Soaplib is an easy to use Python library for publishing SOAP web services using WSDL 1.1 standard, and answering SOAP 1.1 requests. With a very small amount of code, soaplib allows you to write and deploy useful web services. It is designed to be web framework agnostic, with bundled examples of use with specific servers (Zope2, Twisted, CherryPy, WSGI). Soaplib is fast: it relies on lxml for performance intensive aspects such as XML parsing, validation, and namespace mapping. This release includes many bug fixes and API changes designed to improve readability. Highlights of this release are: +Now we have Sphinx docs with working examples: http://soaplib.github.com/soaplib/2_0/ +The Serializer types have been renamed to Model to better fit their use and similarity to “active record” declarative models seen in ORMs. +Standalone xsd generation for ClassSerializer objects has been added. This allows soaplib to be used to define generic XML schemas, without SOAP artifacts. +Annotation Tags for primitive Models has been added. +Custom PortType(s) and Service(s) are now supported. +WSDL generation has been moved out of the Application class and is now handled by a standalone WSDL class. +The soaplib client has been re-written after having been dropped from recent releases. It follows the suds API but is based on lxml for better performance. WARNING: the soaplib client is not well-tested and future support is tentative dependent on community response. It's current location is in a seperate repo at https://github.com/soaplib/soaplib.client +0mq support has been added via a service and client. Again, this is experimental and not fully supported at this point. +Increased test coverage for soaplib and supported servers. Upcoming soaplib organization releases: Tres Seaver has built a WSRP (Web Services for Remote Portlets) library called wsrplib on top of soaplib. This library is being release shortly under the soaplib organization and can currently be found at https://github.com/soaplib/wsrplib . Many of the recent API additions to soaplib were driven by this effort. Once again, this work would not have been possible without the sponsorship of ZeOmega. We are interested in establishing a robust community process to encourage adoption and contribution. Please let us know if you have input on how we can get there; the goal is to provide a solid end-to-end choice for working with SOAP using Python. We'd like to thank ZeOmega (my employer) for sponsoring the work done by myself, Brad Allen and many others to help keep soaplib moving. Special thanks to Burak Arslan. Even though his currently not able to maintain the package he is responsible for a huge amount of leading up to this release. Special thanks also to Tres Seaver who while working on wsrplib provide invaluable input for improving soaplib. Additional thanks go out to everyone who has made suggestions, rants, and most importantly submitted any type of bugfix.
