Decorator syntax
by Rob Cliffe Sept. 3, 2009

Sept. 3, 2009

Hi All, This is my first post to python-dev so I will briefly introduce myself: My name is Rob Cliffe and I am a commercial programmer living in London, UK. I have some 30 years of programming experience but have only been using Python for a couple of years. First I want to say what a fantastic language Python is. It is THE best language for development in my opinion, and a joy to use. My specific issue: I eventually got my head round decorator syntax and realised that what came after the '@… [View More]

Bugs discovered by researchers at Case Western Reserve University
by Boya Sun Sept. 3, 2009

Sept. 3, 2009

Dear Developers, I am a Ph.D student from Case Western Reserve University, specialized at software engineering. Our recent approach analyzes bugs that are being fixed in the issue database, and tries to discover any latent bug instances that are the same as the fixed bug but are left unfixed. We have found some spurious code in your project in this approach, and pointed out these code by comments (sometimes also with patches) to the fixed bugs in the issue DB from which it is discovered as … [View More]

Setting up a buildbot
by Paul Moore Sept. 3, 2009

Sept. 3, 2009

I've just had a look on python.org, but couldn't immediately see a pointer to instructions on what the process is to set up a buildbot. There's a not on setting things up for pybots, but nothing on the core buildbot setup. The reason I'm asking is that I'm thinking of seeing if I could set up a Windows buildbot of some sort, to offer extra coverage. It's early days, yet, but I wonder if someone could answer a few questions for me: - Is there any documentation on how to set up a buildbot? If … [View More]

why different between staticmethod and classmethod on non-callable object?
by xiaobing jiang Sept. 2, 2009

Sept. 2, 2009

hi all: In the svn thunk tree, I find in file Object/funcobject.c, the two functions: sm_init and cm_init have a little different. the cm_init function will check the object is really callable, but the sm_init don't. the code like this: if (!PyCallable_Check(callable)) { PyErr_Format(PyExc_TypeError, "'%s' object is not callable", callable->ob_type->tp_name); return -1; } so when use staticmethod and classmethod on a class variable, there are two … [View More]

Whether to call Py_Finalize when exiting from the child process of a fork from a spawned thread
by Reid Kleckner Sept. 2, 2009

Sept. 2, 2009

Hi all, I'm working on http://bugs.python.org/issue6642 for unladen swallow (because it happens to bite us in a weird way), and Jeff Yasskin told me to ask python-dev what the proper behavior should be at exit from the child process of a fork from a spawned thread. Right now, it seems that there is an assumption that when exiting the process, control will always return through Py_Main, which in turn calls Py_Finalize, to do things like GC and calling atexit handlers. Normally, if you fork a … [View More]

Re: [Python-Dev] Support for Encrypted Zip as python scripts
by Brett Cannon Sept. 1, 2009

Sept. 1, 2009

There is a standard for encrypting entire zip files. And I was looking at the zip docs the other day and zipfile can already decrypt but not encrypt (assuming my memory is accurate; doing this from my phone on vacation).

how important is setting co_filename for a module being imported to what __file__ is set to?
by Brett Cannon Sept. 1, 2009

Sept. 1, 2009

I am going through and running the entire test suite using importlib to ferret out incompatibilities. I have found a bunch, although all rather minor (raising a different exception typically; not even sure they are worth backporting as anyone reliant on the old exceptions might get a nasty surprise in the next micro release), and now I am down to my last failing test suite: test_import. Ignoring the execution bit problem (http://bugs.python.org/issue6526 but I have no clue why this is … [View More]

by Joe Amenta Sept. 1, 2009

Sept. 1, 2009

Hello all, I have released the first alpha version of 3to2 after finishing it for my Google Summer of Code 2009(tm) project. You can get the tarball for this release at http://bitbucket.org/amentajo/lib3to2/downloads/3to2_0.1-alpha1.tar.gz. This requires python 2.7, because it requires a newer version of 2to3 than what comes with 2.6. Release notes are in the RELEASE file. Development happens at http://bitbucket.org/amentajo/lib3to2/, and the source code for this release lives at http://… [View More]
