[issue24018] add a Generator ABC
Stefan Behnel added the comment: should inspect.isgenerator() be changed? Replying to myself, one thing that speaks against this approach is that inspect also has the functions getgeneratorlocals() and getgeneratorstate(), which depend on gen.gi_frame. Cython could emulate that, but normal user code usually can't. It's definitely not part of the Generator protocol but an implementation detail of GeneratorType. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24018 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24020] threading.local() must be run at module level (doc improvement)
Eric Snow added the comment: FYI, I've used thread-local namespaces with success in several different ways and none of them involved binding the thread-local namespace to global scope. I don't think anything needs to be fixed here. The SO answer is misleading and perhaps even wrong. The problem it describes is about sharing the thread-local NS *between function calls*. Persisting state between function calls is not a new or mysterious problem, nor unique to thread-local namespaces. In the example they give, rather than a global they could have put it into a default arg or into a class: def hi(threadlocal=threading.local()): ... class Hi: threadlocal = threading.local() def __call__(self): ... # change threadlocal to self.threadlocal hi = Hi() This is simply a consequence of Python's normal scoping rules (should be unsurprising) and the fact that threading.local is a class (new instance per call) rather than a function (with the assumption of a singleton namespace per thread). At most the docs could be a little more clear that threading.local() produces a new namespace each time. However, I don't think even that is necessary and suggest closing this as won't fix. -- nosy: +eric.snow ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24020 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24019] str/unicode encoding kwarg causes exceptions
Mahmoud Hashemi added the comment: Python already has one approach that fails to decode non-bytestrings: the .decode() method. This is about removing unicode barriers to entry and making the str constructor in Python 3 as succinctly useful as possible. There are several problems the helper does not solve: 1) Usage-wise, str/unicode is used to turn values into text. From a high-level perspective, the content does not change, only the representation format. Should this fundamental operation really require type inspection and explicit try/except blocks every single time? Or should it just work? sorted() does not raise an exception if the values are already sorted, why does str() raise an exception when the value is already a str?* 2) By and large, among developers, keyword arguments are viewed as optional arguments that have defaults which can be overridden. However, that is not the case here; str is not simply str(obj, encoding=sys.getdefaultencoding()). Explicitly passing the keyword argument breaks the call. 3) The helper does not help promote Python adoption when it must be copied and pasted it into new developer's projects. It does not help break down the misconception that unicode is a punishing concept to be around in Python. * This question is posed here rhetorically, but I have gotten variations on it from multiple Python developers in training. -- versions: +Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24019 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24020] threading.local() must be run at module level (doc improvement)
Paul Moore added the comment: That seems to merely be saying that each threading.local() object is distinct, so if you want to share threadlocal data between workers, creating local objects won't work. I think I see what the confusion is (although I can't quite explain it yet, I'll need to think some more about it) but threading.local() needs to be run at global scope is not accurate (for example, if I understand correctly, a class attribute which is a threading.local value would work fine, and it's not global scope. Basically, each time you call threading.local() you get a brand new object. It looks like a dictionary, but in fact it's a *different* dictionary for each thread. Within one thread, though, you can have multiple threading.local() objects, and they are independent. The wrong code in the SO discussion created a new threading-local() object as a local variable in a function, and tried to use it to remember state from one function call to the next (like a C static variable). That would be just as wrong in a single-threaded program where you used dict() instead of threading.local(), and for the same reasons. I don't know what your code was doing, so it may well be that the problem you were encountering was more subtle than the one on the wont_work() function. But threading.local() must be run in global scope is *not* the answer (even if doing that resulted in your problem going away). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24020 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24022] Python heap corruption issue
New submission from Benjamin Peterson: Reported by Hug Bounter to security@ Hello, I would like to report a heap corruption issue in Python/Parser/tokenizer.c:922, affecting latest Python 3.4.3 (from python.org) and also 2.7 ( tested 2.7.9-r1 on Gentoo ). The latest version available - 3.5.0a3 is also affected. It doesn't seem to affect 3.3 branch (tested with 3.3.5-r1 on Gentoo). The issue occurs when a malformed python script is executed by python binary, which results in a out-of-bound read access of heap and therefore a segmentation fault. I couldn't confirm nor deny its exploitability, to my knowledge this would be more of a infoleak, if anything. Nevertheless, as Google Project Zero proved many times, no heap corruption issue should be treated lightheartedly. :-) Hence the reason why I'm reporting it to secur...@python.org I tried to dig into the details of the bug and I have to admit the defeat - the Python Parser is quite a complex beast... What I was able to determine was that given malformed script (attached), the infinite 'for' loop defined in tokenizer.c:900 never reaches any of the exit conditions, which causes a infinite incrementation of *tok-cur and thus reading character by character of the heap, until the heap segment boundary is reached and segmentation fault occurrs.

[issue24020] threading.local() must be run at module level (doc improvement)
Ethan Furman added the comment: Here's a basic outline of what I was trying: --- CONTEXT = None class MyFUSE(Fuse): def __call__(self, op, path, *args): global CONTEXT ... CONTEXT = threading.local() # set several CONTEXT vars ... # dispatch to correct function to handle 'op' Under stress, I would eventually get threading.local objects that were missing attributes. Points to consider: - I have no control over the threads; they just arrive wanting their 'op's fulfilled - the same thread can be a repeat customer, but with the above scenario they would/should get a new threading.local each time Hmmm... could my problem be that even though function locals are thread-safe, the globals are not, so trying to create a threading.local via a global statement was clobbering other threading.local instances? While that would make sense, I'm still completely clueless why having a single global statement, which (apparently) creates a single threading.local object, could be distinct for all the threads... unless, of course, it can detect which thread is accessing it and react appropriately. Okay, that's really cool. So I was doing two things wrong: - calling threading.local() inside a function (although this would probably work if I then passed that object around, as I do not need to persist state across function calls -- wait, that would be the same as using an ordinary, function-local dict, wouldn't it?) - attempting to assign the threading.local object to a global variable from inside a function (this won't work, period) Many thanks for helping me figure that out. Paul, in your SO answer you state: - Just like an ordinary object, you can create multiple threading.local instances in your code. They can be local variables, class or instance members, or global variables. - Local variables are already thread-safe, aren't they? So there would be no point in using threading.local() there. - Instance members (set from __init__ of someother method): wouldn't that be the same problem I was having trying to update a non-threadsafe global with a new threading.local() each time?

The thread safety issue is that if you write over the global in one thread, before another thread has finished, you lose the second thread's values (because they were on the old, lost, namespace.

I only mentioned it to avoid giving any impression that only set at global scope was important. - Instance members (set from __init__ of someother method): wouldn't that be the same problem I was having trying to update a non-threadsafe global with a new threading.local() each time? You'd set vars on the namespace held in the instance variable. It's much like the local variable case, except you are more likely to pass an instance around between threads. It seems to me the take-away here is that you only want to create a threading.local() object /once/ -- if you are creating the same threading.local() object more than once, you're doing it wrong. Well, sort of. You can only create *any* object once :-) There seems to be a confusion (in the SO thread and with you, maybe) that threading.local objects are somehow singletons in that you create them repeatedly and get the same object. That's just wrong - they are entirely normal objects, that you can set arbitrary attributes on.

[issue24019] str/unicode encoding kwarg causes exceptions
Martin Panter added the comment: I don’t think changes to Python 2 are considered here, unless they are bug fixes, and this does not sound like a bug fix. For Python 3, it sounds like you are proposing that str() accept encoding arguments even when not decoding from bytes. It sounds like this would mask the error if you called str(buffer, ascii), and the buffer happened to be an integer or a list, etc, by accident. Also, this woul It seems str() is designed to have two separate modes: 1. str(object) is basically equivalent to format(object), with a warning if “object” happens to be a byte string or array 2. str(object, encoding, ...) is normally equivalent to object.decode(encoding, ...), or if that is not supported, codecs.decode(object, encoding, ...) Your proposal sounds like it would make it easier to confuse these two modes. What should str(b123, encoding=None) do? Why should the behaviour of str(file, encoding) vary depending on whether an ordinary file object or a memory-mapped file is passed? IMO in a perfect Python 4 world, str() would only have a single personality (perhaps always returning an empty string, or a more strict conversion). Making a formatted string representations of arbitrary objects would be left to the format() and repr() functions, and decoding bytes to text would be left to the existing decode() methods and functions, or maybe a separate str.from_bytes() constructor, mirroring int.from_bytes(). -- nosy: +vadmium ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24019 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24019] str/unicode encoding kwarg causes exceptions
Mahmoud Hashemi added the comment: Martin, it sounds that way because that is what is being proposed: Merging and simplifying the two modes. Given the existence of .decode() on bytestrings, the only objects that generally need decoding in Python 2 and 3, the existence of str/unicode's second mode constitutes a design bug. Without a doubt, Python has frequently preferred convenient idioms over EAFP. Look at dict.get for an excellent example of defaults being used instead of forcing users to catch KeyErrors. That conversation could have gone a different way, but Python is better off having stuck to its pragmatic roots. In answer to your questions, Martin, 1) I'd expect str(b123, encoding=None) to do the same thing as str(b123) and 2) I'd expect str(obj) behavior to continue to depend on whether the object passed is string-like. Python is a duck-typed, dynamic language, and dynamic languages are most powerful when their core types reflect usability. Consistency is one of the foremost factors of usability, and having to frequently switch between two call patterns of the str constructor feels inconsistent and unusable. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24019 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23863] Fix EINTR Socket Module issues in 2.7
Gregory P. Smith added the comment: ... Code review: In socket_eintr.5.patch I don't think the thread safety concerns about the s.settimeout() calls being done from Python code should be an issue but I'll ponder that for a bit. When you've got a socket s, why would code ever be calling s.recv() in one thread while calling another method on the same socket s in another thread? That seems unwise. (For UDP it might be a valid thing to do but it still has an odd smell to it) If you're worried about timer resolution, just check that the new timeout value deadline - now is less than the previous timeout value and if not, ensure the value decreases by some small amount. So long as it continually goes down, it will eventually timeout. Even if the duration isn't accurate in the face of a bunch of EINTRs, this is a degenerate case; it should still be reasonable behavior. On POSIX systems using os.times()[4] rather than an absolute time.time(), which can be changed out from underneath the process (even though that is rare on functioning systems), could be useful. But conditionally using that seems overly complex. I wouldn't bother. ... Side discussion Some things in 2.7 related to EINTR have already been fixed in the past few years such as data loss in readline() and IIRC writelines(). Correctness isn't a feature. Do you consider it an API change to prevent an error that nobody relies on or even expects (as PEP 475 notes) and virtually no code is written to properly handle when it _does_ happen? I don't. It is a bug fix. It's mostly a matter of if we can do it sanely and in a maintainable manner. Please don't WONTFIX this issue, I intend to get safe fixes in. ... Motivation The underlying motivation here is to enable the use of a signal based sampling profiler on a program that is using Python 2.7 (entirely, or embedded as one part of a larger C/C++ application). Signals (SIGPROF) used in that scenario cause EINTR returns from syscalls that otherwise rarely (read: never) have them in most environments. Result: Bugs show up making such a sampling profiler impossible to deploy in practice until those issues are fixed. Fixing the Python standard library is high value as it is a higher up place where these can be handled properly as you cannot even use some standard library modules at all otherwise because the unhandled EINTR surfaces too late or causes other unrecoverable errors internally before you see it. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23863 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24019] str/unicode encoding kwarg causes exceptions
Martin Panter added the comment: Okay, I was trying to confirm your proposal in Python 3 terms, because in Python 2, str has a different meaning and I was confused. I agree that the existence of the decoding mode is a design bug, so how would you feel about deprecating it, at least in the documentation? I.e. in Python 3, deprecate usage like str(buffer, utf-8) in favour of buffer.decode(utf-8) or using the codecs module directly. If this was done, it would clearly remove the need for an encoding parameter to str() in all cases. I would be in favour of deprecating the complementary bytes() and bytearray() encoding modes as well. Do you have an example use case in Python 3 that would benefit from always allowing an encoding parameter? I can understand that your to_unicode() function could be useful in Python 2. But in Python 3, byte strings tend to hold raw data that is not necessarily textual at all. There are some places (warts in my opinion) such as the binascii module where ASCII-encoded byte strings are common, but I still don’t think this proposal would be very helpful with that. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24019 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20851] Update devguide to cover testing from a tarball
Carol Willing added the comment: Brett, Is documentation for a testing a tarball dumped for an RC still needed? If so, are the following steps accurate? 1. Download tarball 2. Extract tarball into a directory tar -xzvf release.tar.gz 3. Change directory into release directory cd release 4. Install the release sudo python setup.py install My assumption: After installation above, testing should be similar to the existing devguide instructions for testing.

[issue15582] Enhance inspect.getdoc to follow inheritance chains
Martin Panter added the comment: My example was taken from a package that tends to “properly document” everything in separate documentation files, rather than in the source code. I don’t really think Python should dictate if and how one document their code based on what base classes they use, and pydoc is still useful with code that has no doc strings. But if this is to be the way of the future, perhaps a warning in the “What’s New” page might be a good idea. The inspect.getdoc() documentation should probably also have a “Changed in version 3.5” warning. I guess it would be less automatic, but maybe another option might have been to add an @inherit_docstring decorator, or some explicit way to say a particular API (re)implements an (abstract) API documented elsewhere. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15582 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24020] threading.local() must be run at module level (doc improvement)
Eric Snow added the comment: Think of threading.local this way: instances of threading.local are shared between all the threads, but the effective __dict__ of each instance is per-thread. Basically, the object stores a dict for each thread. In __getattribute__, __setattr__, and __delattr__ it swaps the dict for the current thread into place and then does proceeds normally. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24020 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue23979] Multiprocessing Pool.map pickles arguments passed to workers
Luis added the comment: Thanks for information and explanations. The option of writing a tweaked serialization mechanism in Queue for Pool and implement a sharedmem sounds like fun, not sure if the pure-copy-on-write of forking can be achieved tho, it would be nice to know if it is actually possible (the project mentioned in issue17560 still needs to dump the arrays in the filesystem) As quick fix for us, I've created a simple wrapper around Pool and its map, it creates a Queue for the results and uses Process to start the workers, this works just fine. Simplicity and consistency are great, but I still believe that Pool, in LINUX-based systems, by serializing arguments, creates duplication and works inefficiently, and this could be avoided. Obviously it's not me who takes the decisions and I don't have the time to investigate it further, so, after this petty rant, should we close this bug? : -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23979 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
