[issue12955] urllib2.build_opener().open() is not friendly to "with ... as:"
by Valery Khamenya 12 Apr '15

12 Apr '15

New submission from Valery Khamenya <khamenya(a)gmail.com>: The following intuitive construction with urllib2.build_opener().open() as: ... leads to AttributeError: addinfourl instance has no attribute '__exit__' http://docs.python.org/library/urllib2.html says almost nothing about concept of closing. Could it be possible to add a canonical "with ... as:" example for urllib2.build_opener() ?

[issue11468] Improve unittest basic example in the doc
by Ezio Melotti 24 Mar '15

24 Mar '15

New submission from Ezio Melotti <ezio.melotti(a)gmail.com>: The current example[0] uses assertTrue(element in self.seq) but it would be better to use assertIn instead. The whole example could be changed to something simpler that uses only the assertTrue/assertEqual/assertRaises methods correctly, e.g.: import unittest class TestStringMethods(unittest.TestCase): def test_upper(self): self.assertEqual('foo'.upper(), 'FOO') def test_isupper(self): self.assertTrue('FOO'.isupper()) self.assertFalse('Foo'.isupper()) def test_split(self): s = 'hello world' self.assertEqual(s.split(), ['hello', 'world']) # check that s.split fails when the separator is not a string with self.assertRaises(TypeError): s.split(2) if __name__ == '__main__': unittest.main() [0]: http://docs.python.org/py3k/library/unittest.html#basic-example ---------- assignee: docs@python components: Documentation keywords: easy messages: 130598 nosy: docs@python, eric.araujo, ezio.melotti, michael.foord, ncoghlan, rhettinger priority: low severity: normal stage: needs patch status: open title: Improve unittest basic example in the doc type: feature request versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11468> _______________________________________

[issue12155] queue example doesn't stop worker threads
by STINNER Victor 18 Mar '15

18 Mar '15

New submission from STINNER Victor <victor.stinner(a)haypocalc.com>: The queue doc contains the following example: ------------------ def worker(): while True: item = q.get() do_work(item) q.task_done() q = Queue() for i in range(num_worker_threads): t = Thread(target=worker) t.daemon = True t.start() for item in source(): q.put(item) q.join() # block until all tasks are done ------------------ http://docs.python.org/library/queue.html It doesn't define do_work(), num_worker_threads or do_work(), but my concern is that it doesn't stop worker threads. I consider "t.daemon = True" as an hack to not care about stopping threads. The example should pass a special value to each worker to stop it. For example: <worker> while True: job = queue.get() if job is None: break audio.play(*job) queue.task_done() Main thread: ... threads = [] for i in range(num_worker_threads): t = Thread(target=worker) threads.append(t) t.start() ... for i in range(num_worker_threads): queue.put(None) queue.join() for thread in threads: thread.join() ---------- assignee: docs@python components: Documentation messages: 136601 nosy: docs@python, haypo, pitrou priority: normal severity: normal status: open title: queue example doesn't stop worker threads versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue12155> _______________________________________

[issue9913] Misc/SpecialBuilds.txt is out of date
by Alexander Belopolsky 18 Feb '15

18 Feb '15

New submission from Alexander Belopolsky <belopolsky(a)users.sourceforge.net>: It looks like Misc/SpecialBuilds.txt has not been updated since 2.4. This file is referenced from C-API documentation [1], but is not accessible as a hyperlink. Some of the recommendations in this file are out of date, in particular those that recommend setting make variables where a configure switch is available. I believe it would be best to retire Misc/SpecialBuilds.txt and move still relevant sections to proper .rst files.

[issue12954] Multiprocessing logging under Windows
by paul j3 10 Feb '15

10 Feb '15

New submission from paul j3 <ajipanca(a)gmail.com>: The Windows programming guidelines for the multiprocessing module documentation should include a warning that any logging initialization should be protected by the 'if __name__' block. Otherwise you will get duplicate logging entries for the child processes. This is because the multiprocessing.forking.prepare() function explicitly calls log_to_stderr(), and may implicitly do so again when it imports the parent module, resulting in duplicate logging handlers. ---------- assignee: docs@python components: Documentation messages: 143815 nosy: docs@python, paul.j3 priority: normal severity: normal status: open title: Multiprocessing logging under Windows _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue12954> _______________________________________

[issue17876] Doc issue with threading.Event
by Xavier Ordoquy 16 Dec '14

16 Dec '14

New submission from Xavier Ordoquy: The documentation isn't correct for the threading.Event class under python 3.2. In the threading doc page (http://docs.python.org/3.2/library/threading.html), Event is said to be at the same time a function and a class. This is misleading and lead to a regression for celery under python 3.2 (https://github.com/celery/celery/pull/1333). Could the doc be updated under python 3.2 so that threading.Event leads to the function and threading._Event leads to the class ? Regards, Xavier. ---------- assignee: docs@python components: Documentation messages: 188127 nosy: docs@python, xordoquy priority: normal severity: normal status: open title: Doc issue with threading.Event type: enhancement versions: Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue17876> _______________________________________

[issue9536] defaultdict doc makes incorrect reference to __missing__ method
by John Posner 12 Dec '14

12 Dec '14

New submission from John Posner <jjposner(a)optimum.net>: The documentation for collections.defaultdict is confusing with respect to the __missing__ method. The fact is that a programmer using defaultdict does not need to know anything about __missing__. The attached patch contains a rewrite of the entire section (but not the "defaultdict Examples" section, which is fine. ---------- assignee: docs@python components: Documentation files: defaultdict.patch keywords: patch messages: 113105 nosy: docs@python, jjposner priority: normal severity: normal status: open title: defaultdict doc makes incorrect reference to __missing__ method versions: Python 2.7 Added file: http://bugs.python.org/file18417/defaultdict.patch _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue9536> _______________________________________

[issue16518] add "buffer protocol" to glossary
by Chris Jerdonek 31 Oct '14

31 Oct '14

New submission from Chris Jerdonek: This issue is to add "buffer protocol" (or perhaps "buffer object") to the glossary. The concept is currently described here: http://docs.python.org/dev/c-api/buffer.html#buffer-protocol Éric initially suggested doing this in the comments to issue 13538. Such a glossary entry would be useful because the buffer protocol (or buffer object) should likely be cited, for example, wherever a function accepts a bytes object, bytearray object, or any object that supports the buffer protocol. The str() constructor is one example where this is done: http://hg.python.org/cpython/file/59acd5cac8b5/Doc/library/functions.rst#l1… "Buffer object" might be the more useful term to add to the glossary because it would help to have a briefer way of saying "any object that supports the buffer protocol." (I'm assuming this is what "buffer object" actually means.) The patch for this issue should also do a comprehensive review of occurrences of buffer object/protocol throughout the docs and add or update links and index entries where appropriate. ---------- assignee: docs@python components: Documentation messages: 176042 nosy: chris.jerdonek, docs@python, eric.araujo, ezio.melotti, pitrou priority: normal severity: normal status: open title: add "buffer protocol" to glossary type: enhancement versions: Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue16518> _______________________________________
