[issue2704] IDLE: Patch to make PyShell behave more like a Terminal interface
Phil Webster added the comment: After reading about beginners having difficulty with IDLE's terminal behavior, I wrote a (very) simple patch to disable left clicking in the text area. I realize that this doesn't solve the problem completely (and the fact that there is already a patch here), but I wanted to become familiar with the contribution process.

[issue995907] memory leak with threads and enhancement of the timer class
Charles-François Natali added the comment: IMO, this shouldn't be implemented atop thread, but ought to be a regular thread pool: this way, you won't get behind if some task takes too long to execute, the thread pool can start new threads as needed, and we get the general work submit/cancel (through future) for free. Also, it would probably deserve a new interface in concurrent.futures, as ScheduledExecutor, with new schedule(delay, fn, *args, **kwargs) and schedule_periodic(delay, fn, *args, **kwargs) for one-shot and periodic calls. It would be much more consistant than an ad-hoc implementation in the threading module. -- nosy: +neologix ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue995907 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17862] itertools.chunks(iterable, size, fill=None)
Serhiy Storchaka added the comment: A week ago I implemented chunks() on C for issue17804. This is an equivalent of such Python code for unlimited sequences: def chunks(seq, size, start=0): for i in itertools.count(start, size): yield seq[i: i + size] or simpler for limited sequences: def chunks(seq, size, start=0): for i in range(start, len(seq), size): yield seq[i: i + size] Later I gave up the idea when I saw the insignificance of the benefits. Personally I have such arguments against including it in stdlib: 1. While C implemented chunks() is faster than manual iteration, speed up of real loops is not worth the use of special function. 2. This idiom is used less than I expected (about two dozen times in stdlib, not counting tests and tools) and use chunks() saves too little number of lines. In any case Python implementation is only 2-3 lines. 3. This function is not very well suited for the itertools module, because it works with sequences and not with iterators. -- keywords: +patch nosy: +serhiy.storchaka Added file: http://bugs.python.org/file30177/iter_chunks.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17862 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17935] Failed compile on XP buildbot
David Bolen added the comment: Yeah, the XP buildbot was pretty old, at nasm 2.02, so I updated to the same 2.09 as the Win7 buildbot, restarted the last build and it went through compilation fine. However, then it failed in test_ssl, and in checking, it looks like my Win7 buildbot is failing the same way. I thought it might just be an independent problem, but then found issue 15172 from last June (like Jeremy I have 2.09.02) which seems to say OpenSSL 1.0.1+ needs nasm 2.10. In Jeremy's case it only affected his 64-bit build, so maybe that's why I haven't seen it yet, but perhaps with the recent move to 1.0.1d it can affect 32-bit as well? Ah, or wait, there's also issue 17425 that seems to indicate 1.0.1d may be at fault for that test failure. Anyway, I installed the latest nasm 2.10.07 both both XP and Win7, and flushed the openssl tree in the 3.3 and 3.x build branches. In retrying the XP 3.x build it still fails test_ssl, so I don't think there's anything else I can change on the buildbot side as it looks like fixing that needs us to switch to 1.0.1e -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17935 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

http://docs.python.org/3/reference/simple_stmts.html#the-import-statement
After the Examples, there's a duplicated paragraph:
The public names defined by a module are determined by checking the module’s
namespace for a variable named __all__; if defined, it must be a sequence of
strings which are names defined or imported by that module. The names given in
__all__ are all considered public and are required to exist. If __all__ is not
defined, the set of public names includes all names found in the module’s
namespace which do not begin with an underscore character ('_'). __all__ should
contain the entire public API. It is intended to avoid accidentally exporting
items that are not part of the API (such as library modules which were imported
and used within the module).
The from form with * may only occur in a module scope. Attempting to use it in
class or function definitions will raise a SyntaxError.

[issue17939] Misleading information about slice assignment in docs
New submission from Stefan Chrobot: http://docs.python.org/3/reference/simple_stmts.html#assignment-statements The docs says: If the target is a slicing: The primary expression in the reference is evaluated. It should yield a mutable sequence object (such as a list). The assigned object should be a sequence object of the same type. This seems wrong, because the assigned object can be any iterable: a = [4, 5, 6] a[0:0] = range(1, 4) # a is now [1, 2, 3, 4, 5, 6] -- assignee: docs@python components: Documentation messages: 188738 nosy: docs@python, stefanchrobot priority: normal severity: normal status: open title: Misleading information about slice assignment in docs type: enhancement versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17939 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11354] argparse: nargs could accept range of options count
paul j3 added the comment:
Wouldn't it be simpler to use the re {m,n} notation to grab the appropriate
number of arguments?
In ArgumentParser _get_nargs_pattern we could add:
+# n to m arguments, nargs is re like {n,m}
+elif is_mnrep(nargs):
+nargs_pattern = '([-A]%s)'%nargs
# all others should be integers
where is_mnrep() tests that the nargs string looks like '{m,n}' (or '{,n}' or
'{m,}'). The resulting nargs_pattern will look like
'([-A]{m,n})'
In _format_args() a similar addition would be:
+elif is_mnrep(action.nargs):
+result = '%s%s' % (get_metavar(1)[0], action.nargs)
'FOO{2,5}'
It would take more code to generate
FOO FOO [FOO [FOO [FOO]]]
A matching programmer input would be:
parser.add_argument('Foo', nargs='{2,5}')
though it wouldn't be much work to also translate a tuple.
parser.add_argument('Foo', nargs=(2,5))
I'll try to test this implementation against wm's tests.

[issue17908] Unittest runner needs an option to call gc.collect() after each test
Michael Foord added the comment: I'm afraid I'm inclined to agree with Antoine. This seems a relatively specialised problem and I'd expect to see it solved in the test system rather than in unittest itself. One solution, and something I'd like to see, is a way for test systems to extend the unittest command line handling so that they can add extra options. At the moment it's very painful to do. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17908 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17941] namedtuple should support fully qualified name for more portable pickling
New submission from Eli Bendersky:
[this came up as part of the Enum discussions. Full details in this thread:
http://mail.python.org/pipermail/python-dev/2013-May/126076.html]
namedtuple currently uses this code to obtain the __module__ for the class it
creates dynamically so that pickling works:
result.__module__ = _sys._getframe(1).f_globals.get('__name__', '__main__')
This may not work correctly on all Python implementations, for example
IronPython.
To support some way to pickle on all implementations, namedtuple should support
a fully qualified name for the class:
Point = namedtuple('mymodule.Point', ['x', 'y'])
If the name is a qualified dotted name, it will be split and the first part
becomes the __module__.

[issue14146] IDLE: source line in editor doesn't highlight when debugging
Terry J. Reedy added the comment: 64 bit Win 7 with 32 bit debug build. Patch imported cleanly with all 3 branches. I cannot currently test 2.7. On 3.3 and 3.4, debugger worked fine relative to this issue: editor window highlight tracked line displayed in debugger as far as I checked. Normal selection and Shell Go to file/line highlight seem to work normally. Normal color marking seems not affected. I cannot think of any more manual tests. So if someone else checks 2.7 and it is also ok, I think you should apply this, so if there is any problem, it can show up in other usage. We can deal with a patched tk if and when it happens. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14146 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17942] IDLE Debugger: names, values misaligned
New submission from Terry J. Reedy: The IDLE debugger has subwindows to display name-object bindings for locals and (optionally) globals. They have a gray background. Text is black, object strings get a white background box. The issue is that the white box and text for each name is slightly raised relative to the name. This is somehow especially noticeable to me for something like 'd = 3', resulting in d3 with 3 boxed and raised a bit so it almost looks like a superscript. This is a fairly minor issue, so low priority now unless trivially fixed. But it should be part of polishing IDLE. I am hoping that this is not a tk bug that is terrible to work around. -- components: IDLE messages: 188752 nosy: roger.serwy, terry.reedy priority: normal severity: normal stage: needs patch status: open title: IDLE Debugger: names, values misaligned type: enhancement versions: Python 2.7, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17942 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
