Issue10403 - using 'attributes' instead of members in documentation
by Senthil Kumaran July 4, 2011

July 4, 2011

Hello! http://bugs.python.org/issue10403 is a documentation bug which talks about using the term 'attribute' instead of the term 'member' when it denotes the class attributes. Agreed. But the discussion goes on to mention that, "Members and methods" should just be "attributes". I find this bit odd. If the two terms are used together, then replacing it with attributes is fine. But the term 'methods' cannot be replaced with 'attributes' as it changes the meaning. Take this case, :class:`BZ2File` provides all of the methods specified by the :class:`io.BufferedIOBase`, except for :meth:`detach` and :meth:`truncate`. Iteration and the :keyword:`with` statement are supported. is correct, whereas replacing "methods with attributes" would make it as :class:`BZ2File` provides all of the attributes specified by the :class:`io.BufferedIOBase`, except for :meth:`detach` and :meth:`truncate`. Iteration and the :keyword:`with` statement are supported. It does not seem correct. My stance is, "It is attributes instead of term members and the term method when it denotes methods can be left as such." Can I still hold on to that and modify the patch which Adam has submitted or the 'attribute' substitution everywhere makes sense? Thanks, Senthil

Speed.Python.org
by Jesse Noller July 4, 2011

July 4, 2011

Now that we have the machine, we need to start working on collecting/organizing the resources needed to get a shared codespeed system in place. After speaking with various people, we felt that overloading codespeed-dev, pypy-dev or python-dev with the discussions around this would be sub optimal. I've spun up a new mailing list here: http://mail.python.org/mailman/listinfo/speed Those who are interested in working on or contributing to the speed.python.org project can subscribe there. I personally can not lead the project, and so I will be looking to the current speed.pypy.org team, and python-dev contributors for leadership in this. I got you the hardware and hosting! :) jesse

Threaded asynchronous return from functions
by Aigars Mahinovs July 4, 2011

July 4, 2011

Short version: Could we get def funct( args ): if args == 'good': return 'good' async_return "I'll think about it" if args == '123': do_x() elif args == 'abc': do_y() else: do_z() as equivalent to def do_thinking( args ): if args == '123': do_x() elif args == 'abc': do_y() else: do_z() def funct( args ): if args == 'good': return 'good' t = threading.Thread(target=do_thinking, args=args) t.start() return "I'll think about it" Longer version: I have been doing some multithreaded work lately and have found that often what I find wanting to do is to call a function, have it check it's arguments, possibly do some work and then return to the caller, but still do some extra processing right after that. Currently to accomplish such feat I need to separate the 'extra processing' bit into a separate function and call that in a separate thread. A nice convenience would be a function or statement that would allow to return a value from the current function, but still keep running its code (in a separate thread). Such approach could then be used in many places where async processing is required, such as GUI programming, XMLRPC, web applications, ... with less boilerplate and more obvious code flow. -- Best regards, Aigars Mahinovs mailto:aigarius@debian.org #--------------------------------------------------------------# | .''`.

Extending documentation innacuracies
by Alejandro Santos July 4, 2011

July 4, 2011

Hi, While reading through the Extending and Embedding docs for Python 3.2 I've noticed something. While the "Py_InitModule" does not exists on Py3k, it is still mentioned on the docs: http://docs.python.org/py3k/extending/extending.html#keyword-parameters-for… http://docs.python.org/py3k/extending/windows.html#a-cookbook-approach http://docs.python.org/py3k/faq/extending.html#what-does-systemerror-pyimpo… Should I report a new issue? -- Alejandro Santos http://alejolp.com.ar

I tried to find which commit removes TemporaryFileTests from the testcase list (to see if there is a good reason to do that, or if it's just a mistake): it's somewhere between Python 2.x and Python 3.0, but I didn't find the commit. Is there a tool to detect that a testcase is never executed to ensure that there is no other forgiven testcase?
