[issue11272] input() has trailing carriage return on windows
Duncan Booth kupu...@gmail.com added the comment: If anyone knows how to reproduce the two bugs with a short Python script, I can try to convert it into a test. If you don't mind kicking off some sub-processes then here's a script that shows the bugs. I couldn't figure out how to do a script that would work on Python 3.1 but fail on Python 3.2, because I think to show the problem you have to use the shell to pipe data and Popen on Python 3.1 quotes the pipe character. -- Added file: http://bugs.python.org/file20857/stdintests.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11272 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Other APIs such as PyString_FromStringAndSize() allow exactly this convention. Right. They allow for this because those are object constructors that allow for creating objects without pre-defined content (hence the NULL). The 0 length feature is just a side-effect, not the main reason why we allow NULLs to be passed in as content buffer to those constructors. PyUnicode_Decode() et al. are conversion functions and these require valid content to work on. Passing in a NULL pointer does not fit that specification and so allowing for this would hide programming errors. E.g. an application using PyUnicode_Decode() might have hit a C lib error and forgets to check the pointer for NULL. It then calls PyUnicode_Decode() and the application continues happily without reporting the error. That's a broken application. -- title: Some trivial python 2.x pickles fails to load in Python 3.2 - Some trivial python 2.x pickles fails to load in Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11286 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Antoine Pitrou pit...@free.fr added the comment: PyUnicode_Decode() et al. are conversion functions and these require valid content to work on. Passing in a NULL pointer does not fit that specification and so allowing for this would hide programming errors. Valid content doesn't mean a lot when the length is 0. What is a valid 0-length string compared to an invalid one? What if the pointer is non-NULL but segfaults when trying to dereference it? Is it valid? Moreover, malloc() is allowed by POSIX to return NULL when called with a 0 length: If size is 0, either a null pointer or a unique pointer that can be successfully passed to free() shall be returned. (http://www.opengroup.org/onlinepubs/007904875/functions/malloc.html) ... which means that such a pointer can then, depending on the platform, get passed (legitimately) to PyUnicode_Decode(). So, IMO, practicality beats purity here. Especially since it is bound to land in a bugfix release (3.2.1), which users don't expect to produce regressions in their own code. OTOH, I agree that a NULL pointer combined with non-0 length could produce an explicit error. -- title: Some trivial python 2.x pickles fails to load in Python 3.2 - Some trivial python 2.x pickles fails to load in Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11286 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

In my opinion, unbound methods should be pickled exactly like all the other Python definitions, such as bound methods, top-level functions, and classes: They should be pickled by name. IIUC, the challenge is how to figure out on which class an unbound method is defined. I'm using the term unbound method colloquially, I know it's implemented as a function.

[issue11286] Some trivial python 2.x pickles fails to load in Python 3.2
Alexander Belopolsky belopol...@users.sourceforge.net added the comment: Antoine is right, my patch is only of discussion quality and if my approach gets support, I will produce a more polished patch. While I am fairly certain that this bug should be fixed where it was introduced, namely in the _pickle module, I am not sure patching both load_binstring() and load_short_binstring() is the right approach. It may be better to modify _Unpickler_Read() so that it returns self-input_buffer (or even self-input_buffer + self-next_read_idx) for zero n. This would be a cleaner design similar to that for PyMem_Malloc() et al. (Since _Unpickler_Read() is private API and the comment documenting it does not specify that it returns NULL for n = 0, I think this can be done in a bugfix release. Furthermore, I reviewed the uses of _Unpickler_Read() with variable and thus potentially zero size and one of them is followed by a null check for s.) On the other hand, my patch also eliminates redundant call to _Unpickler_Read() and makes load_binstring() and load_short_binstring() logic similar to that in load_counted_long(). The main advantage, of course is skipping PyUnicode_Decode() which will load a codec potentially triggering an import and execution of python code. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11286 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Well, a theoretical argument could be made that some codec could return a non-empty string when asked to decode an empty bytestring, but I'm not sure it has much practical worth :) I was thinking about that as well. Note that the opposite is quite common, for example any encoding that uses BOM will turn empty unicode string into a non-empty byte string. I don't think a codec that decodes b'' into non-empty string exists, but it would be reasonable for a codec that requires BOM or some other metadata to reject raise an error on b''. If we rely on decode(b'') == '', these errors will go unnoticed. I am going to prepare a Unpickler_Read() patch with tests and play with it a little. It is a good idea to separate performance optimizations from bug fixes anyways.

It went through 0 and 1, and it still has 2 and 3 to yield. We deepcopy it: live_generator_deepcopy = copy.deepcopy(live_generator) The deepcopied generator assumes the same state of the original one. Let's exhaust it: list(live_generator_deepcopy) [2, 3] list(live_generator_deepcopy) [] Pypy also lets us pickle and unpickle the live generator: live_generator_pickled = pickle.dumps(live_generator) live_generator_unpickled = pickle.loads(live_generator_pickled) list(live_generator_unpickled) [2, 3] list(live_generator_unpickled) [] And the original live generator was unchanged by all these operations: list(live_generator) [2, 3] list(live_generator) [] All the above was demonstrated in Pypy.

[issue11297] Make ChainMap() public in the collections module.
R. David Murray rdmur...@bitdance.com added the comment: Yes, that's part of what I find more intuitive about it. I think of the chainmap as a stack. Perhaps if I had a different application (I would use it for either configuration or namespace management) I'd want a different API, but for those two the stack approach seems most natural to me. In particular, since only the top dict can be updated, it seems most natural to pop it off the top of the stack in order to modify the next one down (and then push it back, if desired). If instead the way to modify the next one down is to do parents, then I'm mutating the chainmap I just did the parents call on, but I'm not referencing that object, I'm referencing the one I got back from the parents call. It just seems more natural that the mutation operations should be carried out via a single chainmap object by using pop and push rather than effectively modifying (potentially multiple) chainmap objects by manipulating other chainmap objects. (Yes, I realize that it is really the underlying dicts that are being modified, but conceptually I'm thinking of the chainmap as a single data structure). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11297 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11297] Make ChainMap() public in the collections module.
Raymond Hettinger rhettin...@users.sourceforge.net added the comment: FWIW, the new_child() and parents() part of the API was modeled after contexts in ANLTR where they are needed to overcome the limitations of Django's push/pop style which precludes a context from having multiple, independent children at the same time. The module docstring in the http://code.activestate.com/recipes/577434/ recipe shows how new_child() can be used to easily model both dynamic scoping and nested scoping. The other advantage of the new_child/parents API over the push/pop API is that it overcomes the occasional templating need to keep two copies of the context (before a push and after a push). In some ways, it is more difficult to keep track of a mutating chain that is being continuously pushed and popped. It is simpler to assign a chain to a variable and always know that it is associated with a given template and not have to worry about whether some utility function pushed a new context and failed to pop it when it was done. A push/pop style introduces the same problems as matching matching malloc() with free() in C. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11297 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11300] mmap() large file failures on Mac OS X docfix
New submission from Steffen Daode Nurpmeso sdao...@googlemail.com: Issue 11277 was closed upon the generally accepted conclusion that the failure is that mmap(2) on Mac OS X has a long time known bug (see msg129107, or directly http://lists.apple.com/archives/darwin-development/2003/Jun/msg00141.html). Issue 11277 fixed the problem in the test suite, but it does give end-users no hint that such a problem exists (on the documentation side). And it's my believe that a beginner or even a non-low-level programmer may be lost in an equal situation. (Though one could argue that such a HE should not use mmap(2), but everyone has a first-time somewhen, say.) In addition, there are many people who don't have the chance to work/test on multiple operating systems and/or hardware, and who need the hand of people who are experienced and can give hints on stupidiness or however this word is correctly spelled. (Am i preaching already?) Because Python is expected to be a user-friendly language i do request a documentation patch which gives a hint. I'll apply a patch, but i'm somewhat new to Python and rST etc., so it surely needs a hand.

[issue11252] Handling statement OR assignment continuation '\' on Win32 platform
Łukasz Langa luk...@langa.pl added the comment:
OK, now I know more about glob than I ever wanted to! :) Basically it comes
down to this:
unix os.path.split('\\')
('', '\\')
win32 os.path.split('\\')
('\\', '')
This is why \ is recognized as the root directory on Win32 and as a
non-existent file on Unix.
In case of / both Unix and Win32 treat it as a valid directory separator so
`os.path.split('/')` returns `('/', '')`. This is why / is recognized as the
root directory on both systems.
Does this answer your questions?

[issue11301] cookielib.LWPCookieJar.save() doesn't save cookies
New submission from Mike Cencula m...@cencula.com: I'm trying to use cookielib.LWPCookieJar.save() to save cookies from a website.

[issue11286] Some trivial python 2.x pickles fails to load in Python 3.2
Alexander Belopolsky belopol...@users.sourceforge.net added the comment: I am attaching a new version of issue11286.diff which fixes the issue by removing special handling of n == 0 case from _Unpickler_Read(). Note that _Unpickler_Read() (formerly known as unpickler_read()) only started to return null pointer instead of a pointer to an empty string when given n == 0 after optimizations implemented in issue #9410. This observation makes me more comfortable with changing the behavior of this function because current behavior is itself a regression from 3.1. (An off-topic remark: What was the point of renaming static functions in _pickle.c made in r84653? There is no need to prefix static C functions with an underscore to make them private and the convention seems to be not to use CamelCase in the names of non-CAPI functions.) -- stage: patch review - commit review Added file: http://bugs.python.org/file20870/issue11286.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11286 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11303] b'x'.decode('latin1') is much slower than b'x'.decode('latin-1')
New submission from Alexander Belopolsky belopol...@users.sourceforge.net:
$ ./python.exe -m timeit b'x'.decode('latin1')
10 loops, best of 3: 2.57 usec per loop
$ ./python.exe -m timeit b'x'.decode('latin-1')
100 loops, best of 3: 0.336 usec per loop
The reason for this behavior is that 'latin-1' is short-circuited in C code
while 'latin1' has to be looked up in aliases.py. Attached patch fixes this
issue.

[issue8426] multiprocessing.Queue fails to get() very large objects
Charles-Francois Natali neolo...@free.fr added the comment: Alright, it's normal behaviour, but since it doesn't seem to be documented, it can be quite surprising. A queue works like this: - when you call queue.put(data), the data is added to a deque, which can grow and shrink forever - then a thread pops elements from the deque, and sends them so that the other process can receive them through a pipe or a Unix socket (created via socketpair). But, and that's the important point, both pipes and unix sockets have a limited capacity (used to be 4k - pagesize - on older Linux kernels for pipes, now it's 64k, and between 64k-120k for unix sockets, depending on tunable systcls). - when you do queue.get(), you just do a read on the pipe/socket In multiproc3.py, the items are first appended to the queue, then the sender process is waited on. But when size = 7279, the data submitted reaches 64k, so the writting thread blocks on the write syscall. And since a join is performed before dequeing the item, you just deadlock, since the join waits for the sending thread to complete, and the write can't complete since the pipe/socket is full! If you dequeue the item before waiting the submitter process, everything works fine: t0 = time.time() try: get_t0 = time.time() vals = q.get(timeout=3.) get_duration = time.time() - get_t0 s.join() Now, for the initial report, the problem is related: def child(task_q, result_q): while True: print Getting task... task = task_q.get() print Got task, task[:10] task = task * 1 print Putting result, task[:10] result_q.put(task) print Done putting result, task[:10] task_q.task_done() tasks = [foo, bar, ABC, baz] for task in tasks: print Putting task, task[:10], ... task_q.put(task) print Done putting task, task[:10] task_q.join() for task in tasks: print Getting result... print Got result, result_q.get()[:10] When the child puts results, since they're bigger tha 64k, the underlying pipe/socket fills up. Thus, the sending thread blocks on the write, and doesn't dequeue the result_q, which keeps growing. So you end up storing in the result_q every object before starting to dequeue them, which represents roughly 4 * 3 * 1e8 = 1.2GB, which could explain the out-of-memory errors (and if it's Unicode string it's even much more)... So the moral is: don't put() to much data to a queue without dequeuing them in a concurrent process... -- nosy: +neologix ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8426 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Alexander Belopolsky belopol...@users.sourceforge.net added the comment:
In issue11303.diff, I add similar optimization for encode('latin1') and for
'utf8' variant of utf-8. I don't think dash-less variants of utf-16 and utf-32
are common enough to justify special-casing.
