[ANN] git JSONRPC web service and matching pyjamas front-end
by Luke Kenneth Casson Leighton 29 Jun '10

29 Jun '10

as more than just a proof-of-concept but to get pyjamas out of looking like "a nice toy, doesn't do much, great demos, shame about real life", i've created yet another git repository browser. this one, thanks to pyjamas, obviously runs as both a desktop application and also as a web application - same source code. pyjamasgitweb is actually two independent happily small projects. the first is simply a JSONRPC-based git web server (in python, using python-git) and the second is a matching front-end. the front-end is happily bare but functional. a demo is here (please be nice to it) where you will see immediately a total lack of colour or even borders: http://pyjs.org/pygit if anyone wants the source code, or to help contribute, it's at: git clone gitolite@pyjs.org:pyjamasgitweb to start the server, read the README, install the dependencies, then do: $ cd jsonservice $ python srv.py {path to top level of repository} & $ cd ../pyjamas $ ./build.sh # requires symlink ~/bin/pyjsbuild to sandbox $ firefox http://127.0.0.1:8000/outputJSONRPCService.html & $ python JSONRPCService.py # for the desktop version l.

[ANN] Six, utilities for supporting Python 2 and 3 with the same code base
by Benjamin Peterson 29 Jun '10

29 Jun '10

I've just released for the first time six, a set of helpers for maintaining a code base on Python 2 and 3 simultaneously. It includes fake byte and unicode literals and wrappers for syntax changes between the languages. The license is MIT. You can download it on PyPi: http://pypi.python.org/pypi/six or read the documentation: http://packages.python.org/six/ Bugs can be reported to the Launchpad page: http://bugs.launchpad.net/python-six -- Regards, Benjamin

[ANNOUNCE] PyGObject 2.21.4 - unstable
by Tomeu Vizoso 29 Jun '10

29 Jun '10

Hi, I am pleased to announce version 2.21.4 of the Python bindings for GObject. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://download.gnome.org/sources/pygobject/2.21/ What's new since PyGObject 2.21.3? - Build the cairo shim as a python module so the _gi module stops linking to it (Tomeu Vizoso) - add drawing area demo (John (J5) Palmieri) - sort the demo list (John (J5) Palmieri) - rename iter to treeiter so we aren't using a python reserved word (John (J5) Palmieri) - Fixup for change in buffer API (John (J5) Palmieri) - add ListStore, TreeStore and TreeViewColumn APIs (John (J5) Palmieri) - Add unit test for add_actions user data. (Ignacio Casal Quinteiro) - Pass user_data param when adding actions (Paolo Borelli) - add an exception type to the try/except block (John (J5) Palmieri) - return PyList instead of PyTuple for array, return empty list for NULL arrays (John (J5) Palmieri) - Fix 'make distcheck' (Tomeu Vizoso) - Allow building pygobject without introspection support by providing --disable-introspection to configure. (Tomeu Vizoso) - Make sure that sys.argv is a list and not a sequence. (Tomeu Vizoso) - Force loading the GObject typelib so we have available the wrappers for base classes such as GInitiallyUnowned. (Tomeu Vizoso) - we shouldn't g_array_free NULL pointers (John (J5) Palmieri) - remove unneeded TextIter creation in the tests (John (J5) Palmieri) - add override for TextBuffer (John (J5) Palmieri) - fix up some build issues (John (J5) Palmieri) - make the overrides file git friendly by appending to __all__ after each override (John (J5) Palmieri) - Override Dialog constructor and add_buttons method (Paolo Borelli) - Merge PyGI (Johan Dahlin) Note to packagers: The configure option --enable-pygi has been removed and we build now introspection support by default. It's not recommend for distros, but if needed, you can build PyGObject without requiring gobject-introspection by passing --disable-introspection. When built with introspection support (the default) we require pycairo as a build dependency. We now install one more python module _gi_cairo.so that links to libcairo and depends on pycairo and that should be packaged separately. Blurb: GObject is an object system library used by GTK+ and GStreamer. PyGObject provides a convenient wrapper for the GObject 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 PyGTK, and gnome-python, it can be used to write full featured Gnome applications. Like the GObject library itself PyGObject 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 featured applications. PyGObject requires glib >= 2.22.4 and Python >= 2.3.5 to build. GIO bindings require glib >= 2.22.4. Please remember that this is an unstable release and shouldn't be used in production. Regards, The PyGObject team

Pyro 4.1 released
by Irmen de Jong 28 Jun '10

28 Jun '10

Pyro 4.1 --------- I'm pleased to announce the release of Pyro 4.1! Detailed info here: http://www.razorvine.net/python/Pyro (a page about migration from Pyro 3.x is included) Download Pyro 4.1 here: http://www.xs4all.nl/~irmen/pyro4/download/ License: MIT software license. What is Pyro? ------------- PYthon Remote Objects provides a very easy way of remote communication between python objects somewhere in a network. It enables you to do remote method calls on objects as if they were normal local objects. Objects can be located by a direct identifier or indirectly by logical, humanly-readable names that are managed in a name server. Pyro is designed to be simple (but powerful) so it's only a manner of adding a few lines of code to ignite your objects. Simple example: http://www.razorvine.net/python/Pyro/Example Changes ------- The most important changes compared to Pyro 4.0 are: - socketserver now also implements handleRequests for external event loops - external event loop has been changed slightly, see the updated eventloop example for usage example - threadpool server now has a pool of worker threads that grows/shrinks as needed, between configurable limits - added @Pyro.callback decorator to be able to raise callback exceptions locally as well as on the caller side. Enjoy, Irmen de Jong
