[ANN] Execnet 1.3.0 released
by Ronny Pfannschmidt 14 Feb '15

14 Feb '15

Hello, is my pleasure to announce the release of execnet 1.3.0 availiable at https://pypi.python.org/pypi/execnet/1.3.0 -- Ronny PS: execnet: distributed Python deployment and communication ======================================================== .. _execnet: http://codespeak.net/execnet execnet_ provides carefully tested means to ad-hoc interact with Python interpreters across version, platform and network barriers. It provides a minimal and fast API targetting the following uses: * distribute tasks to local or remote processes * write and deploy hybrid multi-process applications * write scripts to administer multiple hosts Features ------------------ * zero-install bootstrapping: no remote installation required! * flexible communication: send/receive as well as callback/queue mechanisms supported * simple serialization of python builtin types (no pickling) * grouped creation and robust termination of processes * well tested between CPython 2.6-3.X, Jython 2.5.1 and PyPy 2.2 interpreters. * interoperable between Windows and Unix-ish systems. * integrates with different threading models, including standard os threads, eventlet and gevent based systems. Changelog =========== 1.3.0 -------------------------------- - fix issue33: index.txt to correctly mention MIT instead of GPL. - fix issue35: adapt some doctests, fix some channel tests for py3. - use subprocess32 when available for python < 3. - try to be a bit more careful when interpreter is shutting down to avoid random exceptions, thanks Alfredo Deza. - ignore errors on orphan file removal when rsyncing - fix issue34: limit use of import based bootstrap 1.2 -------------------------------- - fix issue22 -- during interpreter shutdown don't throw an exception when we can't send a termination sequence anymore as we are about to die anyway. - fix issue24 -- allow concurrent creation of gateways by guarding automatic id creation by a look. Thanks tlecomte. - majorly refactor internal thread and IO handling. execnet can now operate on different thread models, defaults to "thread" but allows for eventlet and gevent if it is installed. - gateway.remote_exec() will now execute in multiple threads on the other side by default. The previous neccessity of running "gateway.remote_init_threads()" to allow for such concurrency is gone. The latter method is now a no-op and will be removed in future versions of execnet. - fix issue20: prevent AttributError at interpreter shutdown by not trying to send close/last_message messages if the world around is half destroyed. - fix issue21: allow to create local gateways with sudo aka makegateway("popen//python=sudo python"). Thanks Alfredo Deza for the PR. - streamline gateway termination and simplify proxy implementation. add more internal tracing. - if execution hangs in computation, we now try to send a SIGINT to ourselves on Unix platforms instead of just calling thread.interrupt_main() - change license from GPL to MIT - introduce execnet.dump/load variants of dumps/loads serializing/unserializing mechanism. - improve channel.receive() communication latency on python2 by changing the default timeout of the underlying Queue.get to a regular None instead of the previous default -1 which caused an internal positive timeout value (a hack probably introduced to allow CTRL-C to pass through for <python2.5 versions). - extended ssh-syntax to allow passing of command line args, e.g. "ssh= -p 50 hostname". The options are passed to the underlying ssh client binary. Thanks tundish. - fix issue15: interoperability with inspect.getstack(). Thanks Peter Feiner. - fix issue10 : skip PYTHONDONTWRITEBYTECODE test if it we are running with PYTHONDONTWRITEBYTECODE set. - dont try the jython pid fixup on a RemoteIO - avoid accidentally setting exc_info() in gateway_base.py

Cython 0.22 released
by Robert Bradshaw 12 Feb '15

12 Feb '15

I'm pleased to announce the release of Cython 0.22. This release has numerous bug fixes and several new features. It is is available in the usual locations: http://cython.org/release/Cython-0.22.tar.gz https://pypi.python.org/pypi/Cython/0.22 Happy Coding! Robert Features added -------------- * C functions can coerce to Python functions, which allows passing them around as callable objects. * C arrays can be assigned by value and auto-coerce from Python iterables and to Python lists (and tuples). * Extern C functions can now be declared as cpdef to export them to the module's Python namespace. Extern C functions in pxd files export their values to their own module, iff it exists. * Anonymous C tuple types can be declared as (ctype1, ctype2, ...). * PEP 479: turn accidental StopIteration exceptions that exit generators into a RuntimeError, activated with future import "generator_stop". See http://legacy.python.org/dev/peps/pep-0479/ * Looping over ``reversed(range())`` is optimised in the same way as ``range()``. Patch by Favian Contreras. Bugs fixed ---------- * Mismatching 'except' declarations on signatures in .pxd and .pyx files failed to produce a compile error. * Failure to find any files for the path pattern(s) passed into ``cythonize()`` is now an error to more easily detect accidental typos. * In Py2.6/7 and Py3.2, simple Cython memory views could accidentally be interpreted as non-contiguous by CPython, which could trigger a CPython bug when copying data from them, thus leading to data corruption. See CPython issues 12834 and 23349. Other changes ------------- * Preliminary support for defining the Cython language with a formal grammar. To try parsing your files against this grammar, use the --formal_grammar directive. Experimental. * ``_`` is no longer considered a cacheable builtin as it could interfere with gettext. * Cythonize-computed metadata now cached in the generate C files. * Several corrections and extensions in numpy, cpython, and libcpp pxd files.

CrocToy inquiry
by Andrew Kostadis 12 Feb '15

12 Feb '15

Hello, I am working on CrocToy project, which is a big robotic toy with artificial intellect, a mix of an animal and a 3-4 years old kid. After the research on possible main functionality, I decide to use Python as a programming platform. I am looking for help in developing the entire architecture or at least the main functionality modules: – text-to-speech synthesizer – voice recognition – use xbox to maintain a “vision”, simple object distancing and recognition functions – use Python to move (program) servo motors Having a limited programming skills, I am looking for much of help or perhaps someone is interested to get over of programming part of CrocToy’s project. Question is how to let know about my project to as many programmers as possible? If it helps, I can prepare a short overview of my project. Thank you, sorry for imperfect English, Andrew PS I may have troubles of follow answers to my post, please use my e-mail: croctoy(a)gmail.com Thank you, Andrew

fades 1.0
by Facundo Batista 11 Feb '15

11 Feb '15

Hello all, We're glad to announce the release of fades 1.0. fades, a FAst DEpendencies for Scripts, is a system that automatically handles the virtualenvs in the simple cases normally found when writing scripts or simple programs. It will automagically create a new virtualenv (or reuse a previous created one for your script), installing or updating the necessary dependencies, and execute your script inside that virtualenv. You only need to execute the script with fades (instead of Python) and also mark the required dependencies. More details here: https://github.com/PyAr/fades/ To get it: - For debian/ubuntu you have a .deb here: http://taniquetil.com.ar/fades/fades-1.0.deb - Install it in Arch is very simple: yaourt -S fades - Using pip if you want: pip3 install fades - You can always get the multiplatform tarball and install it in the old fashion way: wget http://taniquetil.com.ar/fades/fades-1.0.tar.gz tar -xf fades-1.0.tar.gz cd fades-1.0 sudo ./setup.py install Help / questions: - You can ask any question or send any recommendation or request to the mailing list. http://listas.python.org.ar/mailman/listinfo/fades - Also, you can open an issue here (please do if you find any problem!). https://github.com/PyAr/fades/issues/new Thanks in advance for your time! -- .
