[ANN] pypiserver 1.0.0 - minimal private pypi server
by Ralf Schmitt Oct. 26, 2012

Oct. 26, 2012

Hi, I've just uploaded pypiserver 1.0.0 to the python package index. pypiserver is a minimal PyPI compatible server. It can be used to serve a set of packages and eggs to easy_install or pip. pypiserver is easy to install (i.e. just 'pip install pypiserver'). It doesn't have any external dependencies. http://pypi.python.org/pypi/pypiserver/ should contain enough information to easily get you started running your own PyPI server in a few minutes. The code is available on github: https://github.com/schmir/pypiserver Changes in version 1.0.0 ------------------------ - add passlib and waitress to pypi-server-standalone - upgrade bottle to 0.11.3 - Update scripts/opensuse/pypiserver.init - Refuse to re upload existing file - Add 'console_scripts' section to 'entry_points', so 'pypi-server.exe' will be created on Windows. - paste_app_factory now use the the password_file option to create the app. Without this the package upload was not working. - Add --fallback-url argument to pypi-server script to make it configurable. -- Cheers Ralf

Tryton 2.6 released
by Cédric Krier Oct. 26, 2012

Oct. 26, 2012

Hi, We are happy to announce the 2.6 release of Tryton. What is Tryton ============== Tryton is a three-tiers high level general purpose application platform using either PostgreSQL, MySQL or SQLite as database engine. The core of Tryton (also called Tryton kernel) provides all the necessary functionalities for a complete application framework: data persistence, extensive modularity, users management (authentication, fine grained control for data access, handling of concurrent access of resources), workflow and report engines, web services and internationalisation. Thus constituting a complete application platform which can be used for any relevant purpose. Website: http://www.tryton.org/ What's new ========== This release brings major changes in the API with the introduction of the Active Record pattern. But also the graphical user interface was not left without improvements. And as usual there are many bugfixes, module improvements and new modules (as announced in the previous release news). Of course, migration from previous series is fully supported. Major changes in graphical user interface ----------------------------------------- * Management of model access and create/delete field access. The client is now aware of the model access which allows the disable buttons when the user doesn't have access to it. It is also possible to manage the create/delete event on fields in addition to read/write. * Dynamic size limit on the One2Many, Many2Many and Char It is now possible to limit the size of those fields and the client will enforce it. * Remove "Please wait" box. The popup was annoying because it make the client lost the focus. * Paste in editable list view. It is possible to paste from a spreadsheet to update a set of rows. Major changes on the server side -------------------------------- * Allow to use Reference field in One2Many & Many2Many. In addition to the Many2One, the reverse field could be a Reference field. In the future, the link between Move and Shipments will be done like that instead of having 4 exclusive Many2One fields. * All kind of buttons have been merge into one simple concept. * Active Record: This is the result of refactoring work started 2 years ago. Here are some benefits: * Reduce the amount of code (about 2.2k lines removed) for example on_change_with and getter of Function field can be merged. * Unify access to the value of record if it is stored or not in the database. It allows to remove of values dictionary on on_change method. * Remove loop over ids in getter of Function field: before: def getter(self, ids, name): res = {} for record in self.browse(ids): res[record.id] = ... return res now: def getter(self, name): return self.... * Rationale the register process of Model (use copy of fields etc.) * Remove session in wizard. Now the wizard instance is the session. * Allow to store the views in a XML file instead of the database. This supports the modification of a view without updating the database. A good speedup for designing views. * A new kind of validation has been added the pre_validation. The new 'pre_validation' allows to validate a record without saving it. This is used by the client to validate lines of a One2Many. With 'pre_validation' it is possible to provide feedback to the user as soon as possible and before the record is saved. Modules ------- account ~~~~~~~ * The Trial Balance report displays now the start and end balance in addition to the debit and credit columns. * Double-clicking on Balance Sheet opens accounts. * The Account Chart doesn't show cumulate Debit/Credit by default but only for the current period. * The Aged Balance is computed over all fiscalyears. * The Account Moves have been refactored to include an origin field which allows to easily link it to the master document. They have two number fields for draft and posted. account_stock_continental ~~~~~~~~~~~~~~~~~~~~~~~~~ * Updating cost price create automaticaly a stock accounting move. purchase ~~~~~~~~ * The purchase manages negative quantities on lines, they will generate Return Shipments and Credit Note. stock ~~~~~ * A graph has been added showing the evolution in past and future of the stock level for a product per warehouse. New modules ----------- * stock_lot defines lot of products. * stock_split adds a wizard to split move. * account_fr adds French account chart. * production defines the basics for production management. * stock_supply_production adds automatic supply mechanisms via production requests. Other changes graphical user interface -------------------------------------- * Constant interpolation has been added to line graph. * The group could have a readonly state. * It is possible to define a time format different of the classic '%H:%M:%S'. Other changes on server side ---------------------------- * The ModelSQL.default_sequence has been removed. The sequence fields will no more increase indefinitely. * The time format is validated, so it is possible to enforce the second to 0 for example. * __tryton__.py is replaced by tryton.cfg, a static file. * It is possible to use tuple as Reference value. It is usefull to construct dynamic domain on such field in PYSON. -- Cédric Krier B2CK SPRL Rue de Rotterdam, 4 4000 Liège Belgium Tel: +32 472 54 46 59 Email/Jabber: cedric.krier(a)b2ck.com Website: http://www.b2ck.com/

Learn Python and SQLAlchemy in Antwerp, Belgium
by Mike Müller Oct. 24, 2012

Oct. 24, 2012

Learn Python and SQLAlchemy in Antwerp, Belgium =============================================== So far most of our open courses are in Leipzig, Germany. After an open training right after EuroPython in Florence in July and one after PyCon PL in Poland in September, we now also offer Python training in Antwerp, Belgium [1]. This is in collaboration with Conceptive Engineering [2]. Python for Programmers - November 12 - 14, 2012 ----------------------------------------------- This is an introduction to the Python Programming languages for participants with some programming background in another language. The three days provide a hands-on training covering all basic language features. After the course participants can write their own Python programs. Stress is on pythonic solutions, i.e. taking advantage of Python's strengths while writing elegant and efficient code. See the course page for more information [3]. SQLAlchemy Training - November 15, 2012 --------------------------------------- SQLAlchemy is THE the library to use in the Python world when interacting with databases. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language. This practical course will make sure you understand the concepts behind SQLAlchemy. We will focus on practical patterns of SQLAlchemy usage and see how its use can grow from very simple to more advanced. See the course page for more information [4]. Camelot Training - November 16, 2012 ------------------------------------- Camelot is a framework for developing desktop database applications at warp speed. It is to desktop applications what Django is to web applications. Some see it as a replacement for MS Access, but its tight integration with SQLAlchemy enables a vast amount of more advanced features and possibilities. See the course page for more information [5].

ANN: Urwid 1.1.0 - Usability and Documentation
by Ian Ward Oct. 23, 2012

Oct. 23, 2012

Announcing Urwid 1.1.0 ---------------------- Urwid home page: http://excess.org/urwid/ Manual: http://excess.org/urwid/docs/ Package: http://pypi.python.org/pypi/urwid/1.1.0 About this release: =================== This is a major feature release for Urwid. The first focus for this release has been on improving the usability of container widgets by building a common API that works on all containers. This API allows reading and updating the focus, contents and options across most containers. Urwid's container widgets have grown organically over the years and many lack an API for updating their contents at all. These changes deprecate a number of existing methods and attributes, but continue to support them. Read about the new API here: http://excess.org/urwid/docs/manual/widgets.html#container-widgets The second focus has been improving Urwid's documentation. Urwid's Tutorial, Manual and Reference have been converted from HTML and wiki pages to Sphinx reStructured text. The tutorial has been largely rewritten. It now covers many more aspects of the library including common patterns and the new container API. The Manual has been heavily edited and most of the class and function docstrings have been updated to look their best in the new Reference. The new documentation is available here: http://excess.org/urwid/docs/ See "New in 1.1.0" below for other changes. Planned changes: ================ Urwid currently supports Python versions 2.4, 2.5, 2.6, 2.7, 3.2 and 3.3. That's just too many versions. I plan to drop support for Python 2.4 and 2.5 in the 1.2.x series to clean up some of the Python 3 compatibility code and start taking advantage of the futuristic language features from the year 2008. I will make a greater effort than usual to back port fixes to the 1.1.x series to support users that choose to continue using old versions of Python. New in 1.1.0: ============= * New common container API: focus, focus_position, contents, options(), get_focus_path(), set_focus_path(), __getitem__, __iter__(), __reversed__() implemented across all included container widgets A full description doesn't fit here, see the Container Widgets section in the manual for details * New Sphinx-based documentation now included in source: Tutorial rewritten, manual revised and new reference based on updated docstrings (by Marco Giusti, Patrick Totzke) * New list walker SimpleFocusListWalker like SimpleListWalker but updates focus position as items are inserted or removed * New decoration widget WidgetDisable to disable interaction with the widgets it wraps * SelectableIcon selectable text widget used by button widgets is now documented (available since 0.9.9) * Columns widget now tries to keep column in focus visible, hiding columns on the left when necessary * Padding widget now defaults to ('relative', 100) instead of 'pack' so that left and right parameters are more useful and more child widgets are supported * New list walker "API Version 2" that is simpler for many list walker uses; "API Version 1" will still continue to be supported * List walkers may now allow iteration from the absolute top or bottom of the list if they provide a positions() method * raw_display now erases to the end of the line with EL escape sequence to improve copy+paste behavior for some terminals * Filler now has top and bottom parameters like Padding's left and right parameters and accepts 'pack' instead of None as a height value for widgets that calculate their own number of rows * Pile and Columns now accepts 'pack' instead of 'flow' for widgets that calculate their own number of rows or columns * Pile and Columns now accept 'given' instead of 'fixed' for cases where the number of rows or columns are specified by the container options * Pile and Columns widgets now accept any iterable to their __init__() methods * Widget now has a default focus_position property that raises an IndexError when read to be consistent with new common container API * GridFlow now supports multiple cell widths within the same widget * BoxWidget, FlowWidget and FixedWidget are deprecated, instead use the sizing() function or _sizing attribute to specify the supported sizing modes for your custom widgets * Some new shift+arrow and numpad input sequences from RXVT and xterm are now recognized * Fix for alarms when used with a screen event loop (e.g. curses_display) * Fix for raw_display when terminal width is 1 column * Fixes for a Columns.get_cursor_coords() regression and a SelectableIcon.get_cursor_coords() bug * Fixes for incorrect handling of box columns in a number of Columns methods when that column is selectable * Fix for Terminal widget input handling with Python 3 About Urwid =========== Urwid is a console UI library for Python. It features fluid interface resizing, Unicode support, multiple text layouts, simple attribute markup, powerful scrolling list boxes and flexible interface design. Urwid is released under the GNU LGPL.
