izip not documented in Py3
by Juergen Novak July 6, 2013

July 6, 2013

Hi there, today I was stumpling over a nice video of Raymond Hettinger. He also described izip, which I did not knew before. So I looked into the documentation and did not find it, because it was in 2.x in itertools and in 3.x it is a builtin. But it is not documented as a builtin in 3.x -- either it is not documented in 3.x itertools (what is correct, since it can not be imported from there anymore, I guess). I only did find it in 3.x documentation in a little doc about the conversion … [View More]

[issue11366] xml.etree.ElementTree.Element: docs should mention immediate subelement
by Christian Heimes July 5, 2013

July 5, 2013

Christian Heimes added the comment: The introduction [1] to etree explains it: Element.findall() finds only elements with a tag which are direct children of the current element. IMHO it's also the obvious outcome for anybody familiar with XML and XPath.

[issue6128] Consequences of using Py_TPFLAGS_HAVE_GC are incompletely explained
by Christian Heimes July 5, 2013

July 5, 2013

Christian Heimes added the comment: Python's extension modules aren't consistent. Some places deallocate the object with PyObject_Del(), other places are using PyObject_GC_Del() or simple Py_DECREF(). ---------- nosy: +christian.heimes priority: normal -> low stage: -> needs patch type: -> enhancement versions: +Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue6128> _______________________________________

[issue14206] multiprocessing.Queue documentation is lacking important details
by Garrett Moore July 2, 2013

July 2, 2013

New submission from Garrett Moore <garrettmoore(a)gmail.com>: 1) If cancel_join_thread() is called, data may be lost. This is not explicitly stated. I had multiple writers put() data in a Queue, and wanted to have the workers finish before I began consuming the data. This caused a deadlock because my Queue was not empty, and it seemed like the a way to force my workers finish was to use cancel_join_thread(). This caused data loss. 2) multiprocessing.Queue states "The Queue class is a … [View More]
