Changing PyModuleDef.m_reload to m_slots
by Petr Viktorin April 25, 2015

April 25, 2015

Hello, PEP 489, Redesigning extension module loading [0], is currently discussed on import-sig, but one question calls for a wider audience. As a background, the PyModuleDef structure [1] is currently: struct PyModuleDef{ PyModuleDef_Base m_base; const char* m_name; const char* m_doc; Py_ssize_t m_size; PyMethodDef *m_methods; inquiry m_reload; traverseproc m_traverse; inquiry m_clear; freefunc m_free; }; ... where … [View More]

How to behave regarding commiting
by Facundo Batista April 25, 2015

April 25, 2015

Hola! I'm asking this because quite some time passed since I was active in the development of our beloved language. I'm trying to not break any new rule not known by me. I opened a bug recently [0], somebody else proposed a patch that I like. However, that patch has no test. I will do a test for that code, but then what? Shall I just commit and push? Or the whole branch should be proposed for further reviewing? Thank you!! [0] http://bugs.python.org/issue23887 -- . Facundo Blog: … [View More]

PEP 3152 and yield from Future()
by Victor Stinner April 24, 2015

April 24, 2015

(I prefer to start a new thread, the previous one is too long for me :-)) Hi, I'm still trying to understand how the PEP 3152 would impact asyncio. Guido suggests to replace "yield from fut" with "cocall fut()" (add parenthesis) and so add a __cocall__() method to asyncio.Future. Problem: PEP 3152 says "A cofunction (...) does not contain any yield or yield from expressions". Currently, Future.__iter__() is implemented using yield: def __iter__(self): if not self.done(): … [View More]

Questionable TCP server example
by Andrea Griffini April 23, 2015

April 23, 2015

It's not the first time someone is confused by the server example of https://docs.python.org/3/library/socketserver.html where the receiving side is not making a loop over recv. Moreover the documentation contains a misleading description of what really happens: "The difference is that the readline() call in the second handler will call recv() multiple times until it encounters a newline character, while the single recv() call in the first handler will just return what has been sent from … [View More]

Committing into which branches?
by Facundo Batista April 23, 2015

April 23, 2015

Hola! I just commited a simple improvement to HTTPError repr, and checking in the source code page [0], I see that my commit has a small "default" besides it; and other commits don't have that, but have 2.7, or 3.4, etc... So, question: Did I commit in the correct branch? Should I have done anything different? Thanks! [0] https://hg.python.org/cpython/ -- .

Python 3.x Adoption for PyPI and PyPI Download Numbers
by Donald Stufft April 22, 2015

April 22, 2015

Just thought I'd share this since it shows how what people are using to download things from PyPI have changed over the past year. Of particular interest to most people will be the final graphs showing what percentage of downloads from PyPI are for Python 3.x or 2.x. As always it's good to keep in mind, "Lies, Damn Lies, and Statistics". I've tried not to bias the results too much, but some bias is unavoidable. Of particular note is that a lot of these numbers come from pip, and as of version … [View More]
