Twisted 13.2.0 Release Announcement
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 13.2! The highlights of this release are: * Twisted now includes a HostnameEndpoint implementation which uses IPv4 and IPv6 in parallel, speeding up the connection by using whichever connects first (the 'Happy Eyeballs'/RFC 6555 algorithm). (#4859) * Improved support for Cancellable Deferreds by kaizhang, our GSoC student. (#4320, #6532, #6572, #6639) * Improved Twisted.Mail documentation by shira, our Outreach Program for Women intern. (#6649, #6652) * twistd now waits for the application to start successfully before exiting after daemonization. (#823) * SSL server endpoint string descriptions now support the specification of chain certificates. (#6499) * Over 70 closed tickets since 13.1.0. For more information, check the NEWS file (link provided below). You can find the downloads at https://pypi.python.org/pypi/Twisted (or alternatively http://twistedmatrix.com/trac/wiki/Downloads) . The NEWS file is also available at http://twistedmatrix.com/Releases/Twisted/13.2/NEWS.txt. Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted!

Plumbum v1.4 released
Ever wished the compactness of shell scripts be put into a real programming language? Say hello to Plumbum Shell Combinators. Plumbum (Latin for lead, which was used to create pipes back in the day) is a small yet feature-rich library for shell script-like programs in Python. The motto of the library is “Never write shell scripts again”, and thus it attempts to mimic the shell syntax (shell combinators) where it makes sense, while keeping it all Pythonic and cross-platform. Apart from shell-like syntax and handy shortcuts, the library provides local and remote command execution (over SSH), local and remote file-system paths, easy working-directory and environment manipulation, and a programmatic Command-Line Interface (CLI) application toolkit. http://plumbum.readthedocs.org/en/latest/ Compatibility issue: `plumbum.utils` became `plumbum.path.utils` -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

Re: my favorite line of py code so far
Chris said : I think map is fine if you can use a named function, but if you can't come up with a descriptive name for what you're doing, a comprehension is probably better (as it'll have the code right there). Mapping _ across everything tells you nothing about what it's actually doing OK, this makes a lot of sense. (Any my apologies to Peter Otten if my previous post was overly snarky). How about this? I put the following in my catchall_utility.py module # the oneArg combinator takes a multi-argument calleable # and returns the equivalent single argument calleable oneArg = lambda c: lambda x : c(*x) With example code map(oneArg(P), zip([1,2,3], [6, 5, 4])) To my mind the idea that oneArg(P) is a calleble that behaves exactly like P, with the only difference being oneArg(P) accepts P's arguments packed into a single iterable, is very intuitive. I actually find the oneArg version more readable than the comprehension that unpacks explicitly using *. At this point I probably have equal experience coding Lisp and Py, with the latter more recent, so I don't think this bias can be chalked up to experienced functional programmer, beginner py programmer. To be clear, I was never really intending to keep the _ = lambda c : lambda x : c(*x) map(oneArg(P), zip([1,2,3], [6, 5, 4])) code snippets in my final work product. The purpose of this thread was too fish around for ideas on what to replace it with when I execute the use the unit tests to facilitate refactoring for better names and more professional idioms step. (We never, ever, skip that step, right?) Although it is unlikely you will convince me to use the comprehension in this sort of situation, it's possible someone could convince me to use starmap with P instead of map with oneArg(P). Those two techniques are fully equivalent. But, to my mind, the latter just feels right, and I find that I write fewer bugs when I use idioms that resonate.

As others have said, what you're asking for is actually magic. One of
the rules of Python - one for which I'm not aware of any exceptions -
is that you can always take a subexpression out and give it a new
name:
And it's not just Python: programming languages have been designed
that way since at least the 1960s. People are used to analysing
expressions inside and out according to rules common for almost all
languages.
That's true to at least some extent, but quite a few languages have
differences here and there. In C, there's no such thing as an array
literal, only an initializer list, so:
/* This works: */
int month_days[] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
int this_month_days = month_days[this_month];
/* This doesn't: */
int three = {1, 2, 3, 4, 5}[2];
PHP had similar issues up until a *very* recent version (5.3 or 5.4 or
something), where you couldn't dereference an array returned by a
function:
//Works:
$arr = func();
$val = $arr[5];
//Didn't work until recently, and therefore can't be trusted for
//deployment to random systems across the internet:
$val = func()[5];
JavaScript has magic around the dot and function-call operators, as I
mentioned earlier. Lots of other languages have some little quirk
somewhere that breaks this rule; some have a LOT of quirks that break
this rule. Does Python have any? Aside from parsing oddities like
attribute access on a literal integer[1], are there any cases where
two expressions yielding the same object are in any way different?
ChrisA
[1] You can write (1234).to_bytes(2,'big') but omitting the parens
gives a SyntaxError because it looks like the start of a float
literal.

Continuing the arrogance. Just to put that in perspective, by the way: *EVERYONE* writes vulnerable code. Even Python itself has been found to have had significant exploits (hash randomization had to get backported a long way). There's nothing wrong with fixing security bugs; there's not even a lot wrong with the iterative process of find bug, fix bug, find another bug, fix another bug. There are two major problems with what you did here, Nikos, and they are: 1) Starting with a hopelessly insecure system and then trying to band-aid patch it one vulnerability at a time, which is folly; and 2) Boasting that your system was now secure. The main issue is the boasting, which is utterly unwarranted arrogance. All you have to do is look at how, after boasting previously, you were provably vulnerable - which means that you clearly still had problems while you were boasting. A more humble attitude of Oops, well, that's fixed now without saying Ha ha, now try to break THAT, I'm oh so perfect now would suit you far better, based on your history. ChrisA Ha, ha ha!

We have tested the composition of translation and evaluation of the core for conformance with the primary Python implementa- tion, thereby giving confidence in the fidelity of the seman- tics.

The only thing that would have been better than this would be making it a piece of special syntax rather than something that looks like a function call, but it's too late to change now.

On Q4, you could try Waterloo Graphics http://waterloo.sourceforge.net. Its LGPLv3 and, although Java-based, runs in Python via Py4J. It has built-in mouse interactivity/GUI editors etc that will all be active when used from Python. It is Java Swing-based, so e.g. data points can be drawn as standard clickable Swing components (see http://waterloo.sourceforge.net/R/scatter.html for an example using R [N.B. not interactive on the web site which just shows a bit-map]).

I am not presently using it myself. At the moment a number of people including myself are comparing it with other programs such as XBasic for possible use. 1. How fast can Python do math calculations compared with other languages such as Fortran and fast versions of Basic. I would have to believe that it is much faster than Perl for doing math calculations. 2. Can Python be used to create CGI programs? These are the ones that run on Internet server computers and process data submitted through Web site data entry screens etc. I know that Perl CGI programs will do that. 3. If Python can be used for CGI programming, can it draw charts such as .png files that will then display on Web pages at a Web site? 4. How well does Python work for interactive programming. For example, if a Python program is running on a PC and is drawing a chart, can that chart be modified by simply pressing a key while the Python program is running. I have Perl and Gnuplot program combinations that can do that. Their interactive speed is not that great. But it is adequate for my own uses. 5. Can a running Python program send information to the Windows operating system as if it were typed in from the keyboard? Perl can do that and I would imagine that Python probably has that same capability. -- https://mail.python.org/mailman/listinfo/python-list

PyWart: Packages (oh how thou art lacking!)
The Pros of Python Packages: Python packages require no special syntax to declare which modules are members of the package. Instead, Python simply allows the programmer to utilize the hierarchy of his file system to decide *which* modules are in *which* packages. Sure you've got to create a __init__.py file under the directory which will become the package, which is just one operation to preform, as opposed to writing uses package blah in every damn source file! But the real genius is in the consistency! By utilizing such a novel approach to packaging, the implementation of Python packages remains consistent with Python modules. Let's face it people, packaging by any other means is just re-inventing the wheel! The Cons of Python Packages: 1. No ability to EASILY share state between package members. Sure you can import and inject symbols until you're fingers bleed, but all you've done is create an unmaintainable spaghetti mess! 2. Attempting to use packages to create a hierarchy of library modules is even more difficult and opens a Pandora's box of confusion, circular imports, name errors, unintended side effects, etc, etc... What should a package be anyway? Whilst python packages can be useful, their design is so woefully inadequate as to render them almost useless. To describe the disparities using an example: Imagine if classes were nothing more than an encapsulation of N functions that share information via a global variable self -- no inheritance, no polymorphism, no overloading, no blah blah blah... Sure, i could find a use for such a type, but the usage would be painfully limited. So now we find ourselves faced with the reality of the glaring question -- What the hell should a python package be exactly? A package SHOULD be an extrapolation of the namespace methodology, in the purest form. You start with local scope, then you proceed to module level scope, then package level scope (well, that's my wish anyway!), and finally, global scope[*] Just as class members can share information easily via self, package members should have this ability also. Some food for thought... Namespaces are one honking great idea -- let's do more of those! REFERENCES: [*] Even though Python does not officially support global variables, you can emulate such functionality by injecting objects into __builtins__, since __builtins__ is available in every module namespace. -- https://mail.python.org/mailman/listinfo/python-list
PyWart: Python modules are not so modular after all!
The Pros of Python Modules: Python modules require no special syntax to create, nor do they induce extra indentation in your source code to maintain readability. Simply write some Python code in an editor, save it with a py|pyw extension, throw in a directory that python can find, and WHAMO, you've got yourself an importable module namespace! Of all the package implementations i've seen, Python's use of the source file as a module is absolutely my favorite But don't pucker up your benevolent anus just yet! The Cons of Python Modules: 1. Modules cannot be extended or manipulated by the programmer. Basically the PyGods have handed us modules, but they failed to give us any tools to manipulate them -- heck, they might as well have blessed us an unlimited supply of high carbon steel but cursed us with an atmosphere that does not support combustion. What good is ANY namespace when you cannot override it's fundamental interface? And interfaces are the key to OOP!

[issue19530] cross thread shutdown of UDP socket exhibits unexpected behavior
Charles-François Natali added the comment: After some research... Which is normal, since UDP sockets aren't connected. But UDP sockets can be connected! No, they can't. Connecting a UDP socket doesn't established a duplex connection like in TCP: it's just a shortand for not having to repeat the destination address upon every sendto()/sendmsg(). FYI, the FreeBSD (and OpenBSD) shutdown manpages anticipate calling shutdown on DGRAM sockets. And the Linux connect manpage discusses connecting DGRAM sockets. And since shutdown() is designed for duplex connection, it doesn't really make much sense. It might very well work when you passe SHUT_RD because it can be interpreted as triggering an EOF, but I wouldn't rely on this. Here is the updated Python code. I do expect to try to report this upstream. (Also, I now have C/pthreads code, if you want to see it. As expected, C behaves identically.) So you see it's not a Python bug.

[issue19542] WeakValueDictionary bug in setdefault()pop()
New submission from Armin Rigo: WeakValueDictionary.setdefault() contains a bug that shows up in multithreaded situations using reference cycles. Attached a test case: it is possible for 'setdefault(key, default)' to return None, although None is never put as a value in the dictionary. (Actually, being a WeakValueDictionary, None is not allowed as a value.) The reason is that the code in setdefault() ends in return wr(), but the weakref wr might have gone invalid between the time it was fetched from self.data and the wr() itself, thus returning None. A similar problem occurs in pop(), leading it to possibly raise KeyError even if it is called with a default argument. -- components: Library (Lib) messages: 202510 nosy: arigo priority: normal severity: normal status: open title: WeakValueDictionary bug in setdefault()pop() versions: Python 2.7, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19542 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19499] import this is cached in sys.modules
Terry J. Reedy added the comment: Having import this behave differently from any other import is counter-intuitive I agree. My proposal (by design) does not change the property of executing only when first imported. I merely proposed that the text either start as cleartext or that the decrypted text be saved as a module attribute. *This* would make 'this' *more* like normal modules. Having side-effect code executed on import, as opposed to when running as main, is unusual. (Idlelib.idle is another intentional example, and one which currently has the same problem.) But I agree that this unusual behavior should remain for both. Having module code that is intentionally obfuscated and as about as inefficient as possible without being totally ridiculous is, I hope, unique, and not at all like other modules. Even if Tim wants to keep the literal encrypted, and the rot13 codec is not available in Py3 (?), the decoding would, I believe, be much more efficient using str.translate.

[issue19543] Add -3 warnings for codec convenience method changes
New submission from Nick Coghlan: The long discussion in issue 7475 and some subsequent discussions I had with Armin Ronacher have made it clear to me that the key distinction between the codec systems in Python 2 and Python 3 is the following differences in type signatures of various operations: Python 2 (8 bit str): codecs module: object - object convenience methods: basestring - basestring available codecs: unicode - str, str - str, unicode - unicode Python 3 (Unicode str): codecs module: object - object convenience methods: str - bytes available codecs: str - bytes, bytes - bytes, str - str The significant distinction is the fact that, in Python 2, the convenience methods covered all standard library codecs, but for Python 3, the codecs module needs to be used directly for the bytes - bytes codecs and the one str - str codec (since those codecs no longer satisfy the constraints of the text model related convenience methods). After attempting to implement a 2to3 fixer for these non-Unicode codecs in issue 17823, I realised that wouldn't really work properly (since it's a data driven error based on the behaviour of the named codec), so I'm rejecting that proposal and replacing it with this one for additional Py3k warnings in Python 2.7.7. My proposal is to take the following cases and make them produce warnings under Python 2.7.7 when Py3k warnings are enabled (remember, these are the 2.7 types, not the 3.x ones): - the str.encode method is called (redirect to codecs.encode to handle arbitrary input types in a forward compatible way) - the unicode.decode method is called (redirect to codecs.decode to handle arbitrary input types) - PyUnicode_AsEncodedString produces something other than an 8-bit string (redirect to codecs.encode for arbitrary output types) - PyUnicode_Decode produces something other than a unicode string (redirect to codecs.decode for arbitrary output types) For the latter two cases, issue 17828 includes updates to the Python 3 error messages to similarly redirect to the convenience functions in the codecs module. However, the removed convenience methods will continue to simply trigger AttributeError in Python 3 with no special casing. -- components: Interpreter Core messages: 202512 nosy: ncoghlan priority: normal severity: normal stage: needs patch status: open title: Add -3 warnings for codec convenience method changes type: enhancement versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19543 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19543] Add -3 warnings for codec convenience method changes
Martin Panter added the comment: Just thinking the first case might get quite a few false positives. Maybe that would still be acceptable, I dunno. - the str.encode method is called (redirect to codecs.encode to handle arbitrary input types in a forward compatible way) I guess you are trying to catch cases like this, which I have come across quite a few times: data.encode(hex) # data is a byte string But I think you would also catch cases that depend on Python 2 “str” objects automatically converting to Unicode. Here are some examples taken from real code: file_name.encode(utf-8) # File name parameter may be str or unicode # Code meant to be compatible with both Python 2 and 3: ?xml . . . encoding=iso-8859-1?.encode(iso-8859-1) (data %s\n % len(...)).encode(ascii) -- nosy: +vadmium ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19543 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19543] Add -3 warnings for codec convenience method changes
Marc-Andre Lemburg added the comment: On 10.11.2013 10:20, Nick Coghlan wrote: The long discussion in issue 7475 and some subsequent discussions I had with Armin Ronacher have made it clear to me that the key distinction between the codec systems in Python 2 and Python 3 is the following differences in type signatures of various operations: Python 2 (8 bit str): codecs module: object - object convenience methods: basestring - basestring available codecs: unicode - str, str - str, unicode - unicode Python 3 (Unicode str): codecs module: object - object convenience methods: str - bytes available codecs: str - bytes, bytes - bytes, str - str The significant distinction is the fact that, in Python 2, the convenience methods covered all standard library codecs, but for Python 3, the codecs module needs to be used directly for the bytes - bytes codecs and the one str - str codec (since those codecs no longer satisfy the constraints of the text model related convenience methods). Please remember that the codec sub-system is extensible. It's easily possible to add more codecs via registered codec search functions. Whatever you add as warning has to be aware of the fact that there may be codecs in the system that are not part of the stdlib and which can potentially implement codecs that use other type combinations that the ones you listed above. -- nosy: +lemburg ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19543 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ned Deily added the comment: Update: ActiveTcl 8.5.15.1 is now available and includes the fix for the 10.9 refresh problem documented here. Unfortunately, the built-in versions of Tcl/Tk 8.5 included with the pre-release python.org OS X 64-bit/32-bit x86-64/i386 installers for 3.3.3rc1 and 2.7.6rc1 (as described above) inadvertently broke compatibility with several third-party projects. As a result, as of 3.3.3rc2 and 2.7.6 final, the built-in Tcl/Tk support has been removed and these Pythons once again dynamically link with third-party Tcl and Tk 8.5 frameworks in /Library/Frameworks, such as those from ActiveState.

[issue18861] Problems with recursive automatic exception chaining
Nick Coghlan added the comment: It may not immediately look like it, but I think issue 17828 offers an example of a related problem. In that issue, I didn't want to *change* the exception raised, I wanted to annotate it to say Hey, something I called raised an exception, here's some relevant local state to help you figure out what is going on (in that case, the information to be added is the specific codec being invoked and whether it is an encoding or decoding operation). Setting the context is somewhat similar - you don't just want to know which specific exception happened to be active when the eventually caught exception was first raised - you also want to know which already active exception handlers you passed through while unwinding the stack. So really, what may be desirable here is almost an annotated traceback, where the interpreter can decide to hang additional information off the frame currently being unwound in the exceptions traceback, while leaving the exception itself alone. That's definitely PEP territory, but there are two distinct problems with the current exception chaining mechanism to help drive a prospective design for 3.5 (the status quo doesn't bother me enough for me to work on it myself, but if you're interested Nikolaus...) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18861 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18861] Problems with recursive automatic exception chaining
Nick Coghlan added the comment: Unrelated to my previous comment, I'm also wondering if this may actually represent a behavioural difference between contextlib.ExitStack and the interpreter's own exception handling machinery. ExitStack uses a recursive-iterative transformation for its stack unwinding (see issue 14963), and it needs to do a bit of fiddling to get the context right (see issue 19092). While the contextlib test suite goes to great lengths to try to ensure the semantics of normal stack unwinding are preserved, that definitely doesn't currently cover this case, and I'm thinking the way it works may actually be more like the behaviour Nikolaus expected in the original post (i.e. setting the context as the stack is unwound rather than when the replacement exception is raised). -- nosy: +alonho, hniksic ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18861 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19543] Add -3 warnings for codec convenience method changes
Nick Coghlan added the comment: Martin: you're right, it wouldn't be feasible to check for the 8-bit str encoding case, since the types of string literals will implicitly change between the two versions. However, the latter three cases would be feasible to check (the unicode.decode one is particularly pernicious, since it's the culprit that can lead to UnicodeEncodeErrors on a decoding operation as Python implicitly tries to encode a Unicode string as ASCII). MAL: The latter two Py3k warnings would be in the same place as the corresponding output type errors in Python 3 (i.e. all in unicodeobject.c), so they would never trigger for the general codecs machinery. Python 2 actually already has output type checks in the same place as the proposed warnings, it just only checks for basestring rather than anything more specific. Those two warnings would just involve adding the more restrictive Py3k-style check when -3 was enabled. A Py3k warning for unicode.decode is just a straight this method won't be there any more in Python 3 warning, since there's no way for the conversion from Python 2 to Python 3 to implicitly replace a Unicode string with 8-bit data the way string literals switch from 8-bit data to Unicode text. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19543 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

That API doesn't currently let you change the exception type, only the message (since the codecs machinery doesn't need to change the exception type, and changing the exception type is fraught with peril from a backwards compatibility point of view). BTW: Why don't we make that API a public one ? It could be useful in C extensions as well. Because I'm not sure it's a good idea in general and hence am wary of promoting it too much at this point in time (especially given the severe limitations of what it can currently wrap). I'm convinced it's worth it in this particular case (since being told the codec involved directly makes the meaning of codec errors much clearer and even with the limitations it can still wrap most errors from standard library codecs), and the implementation *has* to be in exceptions.c since it pokes around comparing the exception details to the internals of BaseException to figure out if it can safely wrap the exception or not. Issue 18861 also makes me wonder if there's an underlying structural problem in the way exception chaining currently works that could be better solved by making it possible to annotate traceback frames while unwinding the stack, which also makes me disinclined to add to the public C API in this area before 3.5. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17828 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
