Ezio Melotti ezio.melo...@gmail.com added the comment: Indeed that paragraph is not really clear. I had to read it till the end (verbs for methods and nouns for data attributes) to figure out what it was talking about. Even then it's still not clear what it's trying to say. I *think* it means that if you have a class Foo with a method bar, and you do Foo.bar = 'data', the method will be overridden (so you won't be able to do Foo.bar for the 'data' and Foo.bar() for the method), but the opposite is also true. Moreover I find both the suggestions for avoiding conflicts (capitalizing method names and/or using an underscore) wrong (both against PEP8). Also it never happened to me to have an attribute with the same name of a method, and I think in general it's not a common case (becase, as the paragraph says, methods are verbs and attributes nouns). The whole thing could be rewritten to just say that an attribute name always refers to a single object, either to a method or to some data. -- nosy: +eric.araujo, ezio.melotti, terry.reedy versions: +Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12634 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12632] Windows GPF with Code Page 65001
Bruce Ferris bferri...@bferris.co.uk added the comment: I use code page 65001 because 1) it displays the UTF-8 characters in my text files with echo filename on the command line, and 2) that's Microsoft's official (whatever that means) code page for UTF-8, and 3) it works in cmd.exe. Setting aside why I use it, it IS used by some, and Python shouldn't GPF for ANY reason if it can be easily fixed. Right? Essentially, 65001 makes Microsoft's console output behave properly (at least with the limited characters in Lucinda Console) so I would think Python should consider not blowing up when it's set. To be honest, I just happened to have it set to 65001 to get the output from another program to look right and just happened to run Python to do some quick unrelated calculations. Imagine my surprise when Python blew, especially when all I did was to run it. It's not like I asked it to do any UTF-8 or anthing! Anyway, as far as I understand... Any GPF is a potential back door.

[issue10639] reindent.py converts newlines to platform default
Jason R. Coombs jar...@jaraco.com added the comment: I looked into the possibility of retaining newline characters even for files with mixed newlines, but I've decided that's too intrusive an approach. The current implementation specifically takes measures to strip whitespaces from the ends of lines, so it seems outside the scope of this bug to alter that behavior. So I've taken another stab at a more robust implementation that does newline detection but raises an error if the file contains mixed newlines. Furthermore, it adds an option (--newline) to specify which newline character to use, bypassing the mixed-newline error and allowing the user to override newline detection. Here's a demo run: PS C:\cpython-issue10639 python .\Tools\scripts\reindent.py .\foo.py .\foo.py: mixed newlines detected; cannot continue without --newline PS C:\cpython-issue10639 python .\Tools\scripts\reindent.py --newline CRLF .\foo.py PS C:\cpython-issue10639 python .\Tools\scripts\reindent.py --newline LF .\foo.py PS C:\cpython-issue10639 python .\Tools\scripts\reindent.py .\foo.py I've published this change as https://bitbucket.org/jaraco/cpython-issue10639/changeset/900df5732f93.

New submission from Carl c...@carlbook.com: urllib.URLopener (or urllib.request.URLopener for Python 3) and user defined classes that inherit from these prematurely delete files upon cleanup. Any temporary files downloaded using the .retrieve() method are deleted when an instance of a URLopener is garbage collected.

Re: [issue12638] urllib.URLopener prematurely deletes files on cleanup
urlretrieve is a helper function from urllib module. The way to use
it is:
import urllib.request
urllib.request('http://bugs.python.org')
('/tmp/tmpe873xe', http.client.HTTPMessage object at 0xb72c2f6c)
import os
os.stat('/tmp/tmpe873xe')
posix.stat_result(st_mode=33152, st_ino=4462517, st_dev=2054,
st_nlink=1, st_uid=1000, st_gid=1000, st_size=33128,
st_atime=1311608669, st_mtime=1311608670, st_ctime=1311608670)
Works properly for me 3.3 and 2.7. Is there any service that is
running on your machine that deleting the tmp files as soon as they
are created?

[issue6477] Pickling of NoneType raises PicklingError
Jason R. Coombs jar...@jaraco.com added the comment: I've encountered a use-case where the need to pickle NoneType is more relevant (and difficult to work around). We have a strongly-type Limited Python language, LimPy, which is based on Python (https://bitbucket.org/yougov/limpy). This parser takes, as part of its initialization arguments, a type specification (indicating which types are allowed and not allowed). In some cases, the return value may be `None`, in which case the specification says the type must be `NoneType`. We're attempting to run this parser in a separate process, using the multiprocessing module, which requires that the arguments passed to and from the parser be pickleable. Unfortunately, because `NoneType` is in the type specification, it cannot be passed to the parser. Here's an example of one such type specification (from the test suite): class SomeFunctionNamespace: @signature([IListType], [], None, ListOfInt) def listcount(self, l): return range(len(l)) @signature([IListType], [], None, int) def listlen(self, l): return len(l) # ... @signature([IIntType], [IStringType], IStringType, NoneType) def givespec(self, *args): for a in args: print a Note that we can pickle `str` and `int` just fine. Only type(None) fails. It would be possible to re-write the entire LimPy system (and its child projects) to use a different object where currently NoneType is used, though NoneType is precisely the right thing to be used here except that it can't be pickled. Since type(None) is a fundamental Python type, it strikes me as a bug that it's not pickleable, though I concede that it's also reasonable to interpret this issue as a feature request (as it's never been pickleable). Nick makes some good comments that pickling of NoneType should be done right, but other than that, there haven't been any reasons why in principle NoneType should not be pickleable. NoneType is more akin to `str` and `int` which are pickleable than it is to a function or type(NotImplemented), and this is evident by the way that LimPy uses it (before there was any consideration for pickleability). Therefore, I propose we reconsider that NoneType should be made pickleable. -- nosy: +jaraco ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6477 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue6419] Broken test_kqueue.py on OpenBSD
Charles-François Natali neolo...@free.fr added the comment: Stephan, did you apply the patch? I think the failures you were experiencing on amd64 could be due to issue #12181: OpenBSD's struct kevent definition differs from FreeBSD/NetBSD, which can trigger a segfault on sparc64 (which doesn't allow unaligned access).

[issue12632] Windows GPF with Code Page 65001
Bruce Ferris bferri...@bferris.co.uk added the comment: I disagree with the it's not really a GPF since it calls Abort. Consider the following cmd.exe session... Microsoft Windows [Version 6.0.6002] Copyright (c) 2006 Microsoft Corporation. All rights reserved. D:\chcp 65001 Active code page: 65001 D:\python t.txt Fatal Python error: Py_Initialize: can't initialize sys standard streams LookupError: unknown encoding: cp65001 This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. D:\type t.txt D:\dir t.txt Volume in drive D is DATA Volume Serial Number is 2E61-626C Directory of D:\ 25/07/2011 06:10 PM 0 t.txt 1 File(s) 0 bytes 0 Dir(s) 16,768,655,360 bytes free D:\ This means that, even if it was intentional, from a programatic point of view. the Python process in this case leaves no other indication other than transient bytes in the transient cmd.exe console buffer. No way of redirecting the output and examining it. I strongly disagree with the statement (If it were a true segfault-like error, there would be no message from Python itself.) The no message from Python itself case is shown above. My application handles code page 65001 just fine, no problems. If it attempts to use Windows WriteConsole function and it fails, it tries using WriteFile instead. So, when my application fails and output is redirected, it produces output. But, Python 3.1 doesn't. See the following Microsoft MSDN link, it states the WriteConsole point explicitly... http://msdn.microsoft.com/en-us/library/ms687401%28v=VS.85%29.aspx So, if Python doesn't like Code Page 65001, for whatever reason, it can simply save it on startup, and change it to whatever makes it happy. Then, upon Python exit (including Abort), change it back to 65001 before calling Abort. I'm sorry, but the following is easy in my book... 1) At Startup... Call GetConsoleOutputCP and save that somewhere. If code page is 65001, change it to something that doesn't cause problems by calling SetConsoleOutputCP 2) On Write... If WriteConsole fails, try calling WriteFile instead. 3) At Abort or Exit... Call SetConsoleOutputCP to set it back to whatever it was on Startup. I don't care if your app (Python) can display UTF-8 on Microsoft's cmd.exe console or if it can't. All I'm trying to do is point out a bit of misbehaviour that CAN be easily changed and will make your product more resilient. I don't know the details of how Python deals with character encoding and, quite honestly, I shouldn't need to since it's not my product. however, I DO know how I handle a similiar scenario in my own app. Microsoft made it complicated, not me. But, I can easily get around the problem using the above scenario. If Python can't do it just as easily, then it tells me more about Python's implementation and the people behind Python then it tells me about Microsoft and the people behind Windows. Don't get me wrong, I love Python as a tool for solving certain classes of problems and, please, keep up the good work.

[issue12463] Calling SocketServer.shutdown() when server_forever() was not called will hang
Petri Lehtinen pe...@digip.org added the comment: OK, so this is intentional. But why? Why does it *have to* block on every call? It would be more reasonable to make in not block if serve_forever() is not running and for example add a function to check whether serve_forever() is running or not. If for some reason it has to fail when serve_forever() is not running, a deadlock is still not good.

[issue11877] Change os.fsync() to support physical backing store syncs
Steffen Daode Nurpmeso sdao...@googlemail.com added the comment:
Are you willing to update your patch accordingly?
I'm a vain rooster! I've used fullfsync() in 11877-standalone.1.diff!
Sorry for that, haypo. :-/
11877.fullsync-1.diff uses fullsync() and will instead always be
provided when fsync() is available, to which it will fall back if
no special operating system functionality is available.
I really think this is the cleanest solution, because like this
a user can state i want the strongest guarantees available on
data integrity, and Python does just that.

+
+ The POSIX standart requires that :c:func:`fsync` must transfer the buffered
+ data to the storage device, not that the data is actually written by the
+ device itself. It explicitely leaves it up to operating system implementors
+ whether users are given stronger guarantees on data integrity or not. Some

+ stronger guarantees, i.e., Mac OS X and NetBSD. :func:`fullsync` is
+ identical to :func:`fsync` unless there is such special functionality

+ To strive for best-possible data integrity, the following can be done::
+
+ # Force writeout of local buffer modifications
+ f.flush()
+ # Then synchronize the changes to physical backing store

note: the arm systems i have access to (meego armv7 android sl4a/py4a) both
natively use python 2.6.7; forgive my ignorance if 2.7 series is not expected
to be mature on arm. please also forgive if i should have just disabled ctypes
in setup.py as many of the online (cross-compile) instructions suggest:
disabled_module_list.append('_ctypes')

test_ctypes for a native build of 2.6.7 does not seg fault, but does have the
same test failures:

[issue12464] tempfile.TemporaryDirectory.cleanup follows symbolic links
Nick Coghlan ncogh...@gmail.com added the comment: I agree with Antoine - it's a simple bug introduced by the attempt to allow temporary directories to be correctly cleaned up during interpreter shutdown. The race condition due to the usage of LBYL is shared with the full shutil.rmtree implementation, so the patch looks reasonable to me. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12464 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
