June 25, 2011

Hi, I'm pleased to announce the release of circuits 1.6 [oceans] This release adds full Python 3 compatibility and support while dropping the support for Python 2.5 (a maintainable branch will be kept available).. Also included in this release is the new and exciting "greenlet" support bringing easy-to-use core functionality with a synchronous-like API on top of circuits. This release also includes a number of minor bug fixes and greater test coverage. For more information see the PyPi page:… [View More]

Hello new world ! i’m glad to announce the release of version GOZERBOT 0.9.2, a bot that has been declared dead but has arrived from the pits of hell to serve our people here well ;] Discovered that SQLAlchemy has been fixed in such a way that it was easy to resurrect the thing, and release a new version of it. It’s not my intention to still maintain GOZERBOT as i prefer users to switch to JSONBOT but this switch is to be done in such a way that GOZERBOT users can port their data to JSONBOT … [View More]

ANN: ETS 4.0 released
by Ilan Schnell June 21, 2011

June 21, 2011

Hello, I am happy to announce the release of ETS 4.0. This is the first major release of the Enthought Tool Suite in almost three years. This release removes the 'enthought' namespace from all projects. For example: from enthought.traits.api import HasTraits is now simply:: from traits.api import HasTraits For backwards compatibility, a proxy package 'etsproxy' has been added, which should permit existing code to work. For convenience this package also contains a refactor tool '… [View More]

gcc python plugin and static analyser for CPython sources
by David Malcolm June 21, 2011

June 21, 2011

I've been working on a new plugin for GCC, which supports embedding Python within GCC, exposing GCC's internal data structures as Python objects and classes. The plugin links against libpython, and (I hope) allows you to invoke arbitrary Python scripts from inside a compile. My aim is to allow people to write GCC "plugins" as Python scripts, and to make it much easier to prototype new GCC features. As an example of use for the plugin, I have also been writing a static analysis tool for … [View More]checking the C code of CPython extension modules. So far this only checks the arguments passed to PyArg_ParseTuple*, but I'm working on autodetecting reference counting errors, and turning these into compile-time warnings (See [1]) The plugin is Free Software, licensed under the GPLv3 (or later). The code can be seen here: http://git.fedorahosted.org/git/?p=gcc-python-plugin.git;a=summary and the website for the plugin is the Trac instance here: https://fedorahosted.org/gcc-python-plugin/ The documentation is in the "docs" subdirectory (using sphinx). You can see a pre-built HTML version of the docs here: http://readthedocs.org/docs/gcc-python-plugin/en/latest/index.html It's still at the "experimental proof-of-concept stage"; expect crashes and tracebacks. However, it is already possible to use this to add additional compiler errors/warnings, e.g. domain-specific checks, or static analysis. One of my goals for this is to "teach" GCC about the common mistakes people make when writing extensions for CPython [1], but it could be used - e.g. to teach GCC about GTK's reference-counting semantics, - to check locking in the Linux kernel - to check signal-safety in APIs, etc - rapid prototyping Other ideas include visualizations of code structure. There are handy methods for plotting control flow graphs (using graphviz), showing the source code interleaved with GCC's internal representation, such as the one here: http://readthedocs.org/docs/gcc-python-plugin/en/latest/cfg.html It could also be used to build a more general static-analysis tool. The CPython API checker has the beginnings of this: Example output: test.c: In function ‘leaky’: test.c:21:10: error: leak of PyObject* reference acquired at call to PyList_New at test.c:21 [-fpermissive] test.c:22: taking False path at if (!list) test.c:24: reaching here item = PyLong_FromLong(42); test.c:27: taking True path at if (!item) test.c:21: returning NULL Numerous caveats right now (e.g. how I deal with loops is really dubious). It's disabled for now within the source tree (I need to fix my selftests to pass again...) It perhaps could be generalized to do e.g. {malloc,FILE*, fd} leaks, array bounds checking, int overflow, etc, but obviously that's a far bigger task. So far, I'm just doing a limited form of "abstract interpretation" (or, at least, based on my understanding of that term), dealing with explicit finite prefixes of traces of execution, tracking abstract values (e.g. NULL-ptr vs non-NULL-ptr) and stopping when the trace loops (which is just an easy way to guarantee termination, not a good one, but for my use-case is good enough, I hope. Plus it ought to make it easier to generate highly-readable error messages). Thanks to Red Hat for allowing me to devote a substantial chunk of $DAYJOB to this over the last couple of months. I hope this will be helpful to both the GCC and Python communities.
