Unless you're one of a handful of projects with sufficient leverage, or are indeed a petty jealous person fighting a holy war, the GPL is a bad idea and everyone benefits from a more permissive licence. Oh sure: the GPL hurts everyone, like all the companies who have made quite a lot of money out of effectively making Linux the new enterprise successor to Unix, plus all the companies and individuals who have taken the sources and rolled their own distributions. Relative to what they could have done with a more permissive license? Yes. GPL hurts everyone relative to licenses that don't drive wedges and prevent interoperability between software. You might argue that GPL is sometimes better than proprietary closed source, and I won't disagree, but it's nearly always worse than other open source licenses. P.S. And the GPL isn't meant to further the cause of open source: it's meant to further the Free Software cause, which is not at all the same thing. It doesn't matter what the GPL meant to do, it matters what it does, which is hurt everyone (relative to almost all other licenses). Before you ridicule other people's positions, at least get your terminology right. I don't agree with FSF's defintion of free software and refuse to abide by it. GPL isn't free software; any software that tells me I can't compile it in with a closed source API isn't free. Period. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
Re: Fastest way to calculate leading whitespace

Extract all words that begin with x
Hello
I am trying to find if there is a string OR list function that will
search a list of strings for all the strings that start with 'a'
return a new list containing all the strings that started with 'a'.
I have had a search of Python site I could not find what I am
looking for, does a function like this exist?
The only one that I think could work is, use the string
function .count()
algorithm: to exract all the words inside a list that start with 'a'
- make sure the list is arranged in alphabetical order
- convert the list to a big string
- use list_string.count(',a') to obtain the index where the last 'a'
word occurs
- convert back into string (yes this is a REAL hack :P)
- and then create a new list, ie, new_list = list[0:32]
- return new_list
Ok that algorithm is terrible, I know, I just realise that it wont
work for letters after 'a'. So if anyone could suggest a function or
algorithm it would be extremely helpful

Because I've seen people specifically state that their purpose in GPLing small libraries is to encourage other people to change their behavior. I take those statements at face value. Certainly RMS carefully lays out that the LGPL should be used sparingly in his Why you shouldn't use the Lesser GPL for your next library post. (Hint: he's not suggesting a permissive license instead.) Sure, but all he's asking you to do is to make the software available under a GPL-compatible licence. [...] rst2pdf was licensed under the MIT license before I started contributing to it, and there is no way I was going to even consider adding patches for a GPLed package (which would certainly have to be GPLed) into the rst2pdf repository. (Say what you will about how sometimes differently licensed code can be combined, but RMS has to share quite a bit of the blame/credit for the whole combining licenses FUD.) I think the FSF are quite clear about combining licences - they even go to the trouble of telling you which ones are compatible with the GPL - so I don't see where FUD comes into it, apart from possible corner cases where people are trying to circumvent the terms of a licence and probably know themselves that what they're trying to do is at the very least against the spirit of the licence. Even then, warning people about their little project to make proprietary plugins, or whatever, is not really FUD. As for rst2pdf, what your modifications would mean is that the software would need to be redistributed under a GPL-compatible licence. I'll accept that this does affect what people can then do with the project, but once again, you've mentioned at least one LGPL- licensed project which was previously in this very situation, and it was never actually GPL-licensed itself. Here's the relevant FAQ entry: http://www.gnu.org/licenses/gpl-faq.html#LinkingWithGPL [...] This is exactly the same situation that Carl was describing, only with two different open source packages rather than with a proprietary package and a GPL package. The whole reason people use words like force and viral with the GPL is that this issue would not have come up if svglib were MIT and rst2pdf were GPL. (Note that the LGPL forces you to give back changes, but not in a way that makes it incompatible with software under other licenses. That's why you see very few complaints about the LGPL.) Actually, the copyleft licences don't force anyone to give back changes: they oblige people to pass on changes. [...] But I have definitely seen cases where people are offering something that is not of nearly as much value as they seem to think it is, where one of the goals is obviously to try to spread the GPL.

Re: accessing superclass methods from subclass
ben wrote: Ok, thanks for the info. What would be a better way to do this? What I'm trying to do is treat things in a reasonable OOP manner (all fairly new to me, esp. in Python). Here's a made-up example with a little more context. Let's say you're making a drawing program that can draw various shapes. So in the interest of not repeating oneself, I want a class Shape that handles everything that shapes have, such as a color, and a location. Then I can subclass Shape to create Square, which has code specific to drawing a square (e.g. 4 equal sides). So, like this: class Shape: x = 0 y = 0 def setColor(self,color): self.color = color def setLocation(self,x,y): self.x = x self.y = y def getLocation(self): return [self.x,self.y] class Square(Shape): size = 0 def __init__(self,size): self.size = size def draw(self): location = getLocation() # code to draw shape from location[0],location[1] at size size # etc... It seems to me that you would want the location code handled in the Shape class so that I'm not rewriting it for Circle, Triangle, etc., but I'm not allowed to call any of those methods from the subclass. I must be thinking of this in the wrong way. Help? thanks! Hi Ben, Please do not top post. You already been given good advices, especially the one suggesting to go through the tutorial. You're making basic mistakes here. Here is a very simple version of your code. class Shape: def __init__(self, x=0, y=0): self.x = 0 self.y = 0 self.color = None def draw(self): print 'drawing %s' % self class Square(Shape): def __init__(self,size): self.size = size def draw(self): Shape.draw(self) # this is one way to call the base class method location = (self.x, self.y) # code to draw shape from self.x, self.y at size self.size # etc... mySquare = Square(5,2) mySquare.color = 'red' print mySquare.x 5 Since your attributes are flagged as public, you don't really need setters getters.

Relative to what they could have done with a more permissive license? Well, yes. Some people would have it that the only reason why BSD variants never became as popular as Linux (or rather, GNU/Linux, but lets keep this focused) is because the litigation around the BSD code base scared people away. Yet I remember rather well back in the mid-1990s when people using the same proprietary-and-doomed platform as myself started looking into Unix-flavoured operating systems, and a group of people deliberately chose NetBSD because of the favourable licensing conditions and because there was a portability headstart over Linux, which at the time people seriously believed was rather non- portable. So, that scary ATT myth can be sunk, at least when considering its impact on what people were doing in 1994. Although the NetBSD port in question lives on, and maybe the people responsible all took jobs in large companies, its success on that platform and its derivatives has been dwarfed by that of the corresponding Linux port. Yes. GPL hurts everyone relative to licenses that don't drive wedges and prevent interoperability between software. I can think of another case, actually connected to the above proprietary platform and its practitioners, where software licensing stood in the way of just getting on with business which is what you seem to be advocating: a company released their application under the GPL, except for one critical library which remained proprietary software. Now, although you can argue that everyone's life would be richer had the GPL not prohibited interoperability (although I imagine that the application's licensing actually employed an exception to glue everything together in that particular case), a community never formed because people probably assumed that their role would only ever be about tidying up someone else's code so that the original authors could profit from it. All the GPL is designed to do in such cases is to encourage people to seek control (in terms of the four freedoms) of all the technology, rather than be placated by the occasional airdrop of proprietary software and to be convinced never to explore the possibility of developing something similar for themselves. The beneficiary of the refusal to work on the above application was the GPL-licensed Inkscape, which might not be as well-liked by many people, but it does demonstrate, firstly, that permissive licences do not have the monopoly on encouraging people to work on stuff, and secondly, that actually going and improving something else is the answer if you don't like the licensing of something. You might argue that GPL is sometimes better than proprietary closed source, and I won't disagree, but it's nearly always worse than other open source licenses. For me, I would argue that the GPL is always better than proprietary closed source, recalling that the consideration is that of licensing and not mixing in other concerns like whether a particular program is technically better. In ensuring that an end-user gets some code and can break out those four freedoms on it, it is clearly not worse than other open source licenses, and I don't accept that this is some rare thing that only happens outside a theoretical setting on an occasional basis. P.S. And the GPL isn't meant to further the cause of open source: it's meant to further the Free Software cause, which is not at all the same thing. It doesn't matter what the GPL meant to do, it matters what it does, which is hurt everyone (relative to almost all other licenses). This is your opinion, not objectively established fact. Before you ridicule other people's positions, at least get your terminology right. I don't agree with FSF's defintion of free software and refuse to abide by it. GPL isn't free software; any software that tells me I can't compile it in with a closed source API isn't free. Period. Well, if you can't (or can't be bothered) to distinguish between what is known as Free Software and open source, then I'm hardly surprised that you take offence at people releasing software for one set of reasons while you only consider another set of reasons to be valid ones.

Just upgraded on my Windows 7 machine my copy of 2.6.4 to 2.6.5. However doing sys.version still shows 2.6.4 even so python.exe is dated 19. March 2010 with a size of 26.624 bytes. Is this a known issue? Or did I do something wrong? If I install to a new folder all is well, but I would have to install all my other stuff again (kinterbasdb, matplotlib, sphinx etc etc).

Re: Is Python a functional programming language?
Samuel Williams, 10.05.2010 14:24: Is Python a functional programming language? No. Python is a multi-paradigm language. But it does have functions (and methods) as first-class objects. Is this a paradigm that is well supported by both the language syntax and the general programming APIs? I'd say so, but it certainly depends on what functional language features you desire. I heard that lambdas were limited to a single expression ... which is a good thing. An expression in Python can do pretty complex things already. Not allowing more puts a limit to code readability degradation. and that other functional features were slated for removal in Python 3... is this the case or have I been misinformed? No such functionality has been removed in Py3, and in fact, several core language features were adapted to make functional programming easier and more efficient. Finally, even if Python supports functional features, is this a model that is used often in client/application code? From my point of view, yes. But the beauty is that Python is multi-paradigm, so you're not restricted to functional language features. Stefan -- http://mail.python.org/mailman/listinfo/python-list
Re: Is Python a functional programming language?
Samuel Williams a écrit : Dear Friends, Is Python a functional programming language? Depends on your definition of functional programming language, but well, not really. It's mostly an imperative, object-oriented (but not pure-object) language. It has some restricted support for some functional idioms but trying to use it a true FPL would be a waste of time (both developper's and computer's). Is this a paradigm that is well supported by both the language syntax and the general programming APIs? No. I heard that lambdas were limited to a single expression, True. and that other functional features were slated for removal in Python 3... False. Some FP-inspired functions and types are moving from builtins to a dedicated module, but they are still available. is this the case or have I been misinformed? Finally, even if Python supports functional features, is this a model that is used often in client/application code? Once again, depends on your definitions of what's functional.

My guess is you mixed tabs and spaces. One tab is always treated by the

indentation levels in your code.
Though if it were exactly as you show it, you'd be getting a syntax
error, because even there, it looks like the indentation of your `def

three columns relative to the other methods.

Because I've seen people specifically state that their purpose in GPLing small libraries is to encourage other people to change their behavior. I take those statements at face value. Certainly RMS carefully lays out that the LGPL should be used sparingly in his Why you shouldn't use the Lesser GPL for your next library post. (Hint: he's not suggesting a permissive license instead.) Sure, but all he's asking you to do is to make the software available under a GPL-compatible licence. I'll be charitable and assume the fact that you can make that statement without apparent guile merely means that you haven't read the post I was referring to: http://www.gnu.org/philosophy/why-not-lgpl.html [...] rst2pdf was licensed under the MIT license before I started contributing to it, and there is no way I was going to even consider adding patches for a GPLed package (which would certainly have to be GPLed) into the rst2pdf repository. (Say what you will about how sometimes differently licensed code can be combined, but RMS has to share quite a bit of the blame/credit for the whole combining licenses FUD.) I think the FSF are quite clear about combining licences - they even go to the trouble of telling you which ones are compatible with the GPL Yes, but one of the things they are quite clear on is that the overall work must be licensed as GPL, if any of the components are licensed as GPL. They claim this is true, even if a non-GPL work dynamically links to a GPL work. - so I don't see where FUD comes into it, apart from possible corner cases where people are trying to circumvent the terms of a licence and probably know themselves that what they're trying to do is at the very least against the spirit of the licence. Legally, I don't think they can dictate the license terms of, e.g. clisp just because it can link to readline. But practically, they DID manage to do this, simply because Bruno Haible, the clisp author, was more concerned about writing software than spending too much time sparring with Stallman over the license, so he finally licensed clisp under the gpl. clisp *could* use readline, but didn't require it; nonetheless Stallman argued that clisp was a derivative of readline. That case of the tail wagging the dog would be laughable if it hadn't worked. In any case, Stallman's success at that tactic is probably one of the things that led him to write the paper on why you should use GPL for your library. (As an aside, since rst2pdf *can* use GPL-licensed svglib, it could possibly be subject to the same kind of political pressure as clisp. But the fact that more people are better informed now and that the internet would publicize the dispute more widely more quickly means that this is a battle Stallman is unlikely to wage at this point, because if the leader of any such targeted project has enough cojones, the FSF's inevitable loss would reduce some of the FUD dramatically.) Even then, warning people about their little project to make proprietary plugins, or whatever, is not really FUD. I think that, legally, they probably don't have a leg to stand on for some of their overarching claims (e.g. about shipping proprietary software that could link to readline, without even shipping readline). But morally -- well, they've made their position reasonably clear and I try to abide by it. That still doesn't make it not really FUD. I'd call this sort of badgering copyright misuse myself. As for rst2pdf, what your modifications would mean is that the software would need to be redistributed under a GPL-compatible licence. That's parsing semantics rather finely. In practice, what it really means is that the combination (e.g. the whole program) would effectively be GPL-licensed. This then means that downstream users would have to double-check that they are not combining the whole work with licenses which are GPL-incompatible, even if they are not using the svg feature. Hence, the term viral. I'll accept that this does affect what people can then do with the project, but once again, you've mentioned at least one LGPL- licensed project which was previously in this very situation, and it was never actually GPL-licensed itself. Here's the relevant FAQ entry: http://www.gnu.org/licenses/gpl-faq.html#LinkingWithGPL Yes, I've read that, but this is much more informative: http://www.gnu.org/licenses/gpl-faq.html#GPLInProprietarySystem A system incorporating a GPL-covered program is an extended version of that program. The GPL says that any extended version of the program must be released under the GPL if it is released at all. This makes it clear that the

I will just add that I believe that Apache-style licensing could not work in the absence of GPL software. IOW, I believe that GPL confers a form of herd immunity to Open Source in general, and Stallman gets full credit for creating the idea of GPL to protect Open Source. I believe that Stallman understands this perfectly well and it in part represents why he is so opposed to non-GPL licensing; it makes sense that he feels some resentment toward the freeloading from the rest of the Open Source community. OTOH, I also believe that having only GPL would destroy Open Source as a viable development environment and community; it's too restrictive for some very valuable projects (including Python in specific, to bring this back on topic). Each project needs to think carefully about its relationship to the Open Source ecosystem and community before deciding on a license.

Turbogears 2 training this weekend in Washington, DC USA
Hi all, Sorry for the short notice. We (the Zope/Python Users Group of DC) are having a TurboGears 2 training class this weekend in Washington, DC USA taught by core developer Chris Perkins. Please consider attending! And, I would appreciate you spreading the word to anyone you think may be interested as well. Details are here: http://www.meetup.com/python-meetup-dc/messages/10123013/ And here is a taste: --- The DC Python Meetup is pleased to present Turbogears 2 training, delivered by Turbogears core developer Christopher Perkins. You can register now at http://tg2-class.eventbrite.com/ Turbogears is a modern python web framework with a powerful ORM (the one and only SQLAlchemy), designer friendly templates, and a widget system that simplifies Ajax development. If you're a web developer interested in expanding your toolkit or a python developer who wants to dabble in the web space, this training is an excellent opportunity to learn an agile and mature web framework. The training itself will be wonderfully practical, taking you from basic setup to a real application over the course of a day. You're invited to bring your own data, so that you can work with Chris to start migrating that legacy PHP app you have sitting around to Python beauty. This hands-on training aims to bring students up to speed with TurboGears 2, its administration interface, and touch common deployment scenarios. Students will also get to customize auto generated forms and tables. --- I hope to see you there!

The fact is, I know the man would force me to pay for the chocolate, so in some cases that enters into the equation and keeps me from wanting the chocolate. This isn't whining; just a common-sense description of reality. Personally, I think this use of the word force is much less inflammatory than the deliberate act of co-opting the word freedom to mean if you think you can take this software and do anything you want with it, you're going to find out differently when we sue you.

Problem displaying jpgs in Tkinter via PIL
Hi everyone, I'm new to Python and have been playing around with it using the Enthought Python distribution for Mac OS X 10.6.3 (EPD academic license, version 6.1 with python 2.6.4). It's been great learning the basics, but I've started running into problems when I'm trying to use the PIL library with Tkinter. All I'm trying to do is display a JPG as a Tkinter label: # code below: from Tkinter import * import Image, ImageTk def main(): filename = images/testimg.jpg imgPIL = Image.open(filename) root = Tk() imgTK = ImageTk.PhotoImage(imgPIL) label = Label(root, image=imgTK) label.pack() root.mainloop() main() # end of code It all works fine when I'm just using GIF images through Tkinter's photoimage object, but as soon as I'm trying to convert an image through ImageTk, I get the following error: ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/6.1/lib/python2.6/site-packages/PIL/_imagingtk.so, 2): Library not loaded: /sys...@rpath/Tcl Referenced from: /Library/Frameworks/Python.framework/Versions/6.1/lib/python2.6/site-packages/PIL/_imagingtk.so Reason: image not found I have no idea what that means, but I've always assumed the EPD includes all the stuff that's needed to make Tkinter work with PIL.

Precisely because there *is* force involved: copyright law is enforced, ultimately, by police with threats to put you in a box forcibly. But that force, it must be recognised, comes from the force of law. The GPL, and all free software licenses, do *not* force anyone to do anything; exactly the opposite is the case. Free software licenses grant specific exceptions to the enforcement of copyright law. They grant freedom to do things that would otherwise be prevented by force or the threat of force. This is obvious when you consider what would be the case in the absence of any free software license: everything that was prohibited is still prohibited in the absence of the license, and indeed some more things are now prohibited as well. Conversely, in the absence of any copyright law (not that I advocate that situation), copyright licenses would have no force in or behind them. So I object to muddying the issue by misrepresenting the source of that force.

Your XML message is an XML RPC message. You will use xmlrpclib like this:
server_proxy = xmlrpclib.ServerProxy(('somehost.com', 80))
result = server_proxy.search()
The call to server_proxy.search will result in an actual XML RPC
message being sent.
Read up on the xmlrpclib documentation here:

[issue8674] audioop: incorrect integer overflow checks
New submission from Tomas Hoger tho...@redhat.com: SVN commit r64114 added integer overflow checks to multiple modules. Checks added to audioop module are incorrect and can still be bypassed: http://svn.python.org/view/python/trunk/Modules/audioop.c?r1=64114r2=64113 - audioop_tostereo - should be fine, but relies on undefined behaviour - audioop_lin2lin - undetected overflow: size=1, size2=4, len=0x4001 - audioop_ratecv - undetected overflow: nchannels=0x5fff (32bit) - audioop_ulaw2lin - undetected overflow: size=4, len=0x4001 - audioop_alaw2lin - same as audioop_ulaw2lin - audioop_adpcm2lin - undetected overflow: size=4, len=0x2001 Most of these are triggered by large fragment as an input. Attached patch replaces checks added in r64114 by checks using INT_MAX. -- components: Extension Modules files: python2.6-audioop-int-overflows.diff keywords: patch messages: 105434 nosy: thoger priority: normal severity: normal status: open title: audioop: incorrect integer overflow checks type: security versions: Python 2.6 Added file: http://bugs.python.org/file17281/python2.6-audioop-int-overflows.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8674 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8674] audioop: incorrect integer overflow checks
Mark Dickinson dicki...@gmail.com added the comment: Thanks for the patch. I agree that undefined behaviour (e.g., from signed overflow) should be avoided where at all possible. Do you have any Python examples that failed to trigger the overflow on your platform? If so, it would be useful to add them to Lib/test/test_audioop.py as extra testcases. One other question: is there something about the formats that audioop is dealing with that limits sizes to INT_MAX (rather than PY_SSIZE_T_MAX, for example)? I'm not really familiar with audio formats. As an aside, I also find it strange that the code raises MemoryError in these cases, since these exceptions can be raised even when there's plenty of memory available. IMO MemoryError should only be raised as a result of a failed attempt to allocate memory from the system. Some other exception---perhaps OverflowError---would seem more appropriate here. -- nosy: +mark.dickinson ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8674 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8674] audioop: incorrect integer overflow checks
Mark Dickinson dicki...@gmail.com added the comment: Okay, it looks to me as though all those 'int' lengths should really be 'Py_ssize_t'. I don't think that's something we can change in 2.6, though; probably not in 2.7 either, since we're getting too close to the release. It can and should be changed in py3k, though. I'll review this patch and (assuming it looks good) apply it to the 2.x branches. It would be great to have some tests, though. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8674 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4256] optparse/argparse: provide a simple way to get a programmatically useful list of options
R. David Murray rdmur...@bitdance.com added the comment: zsh's completion system is completely programmable. I looks like it would be pretty easy to add generic 'python script' support widgets(*) using this hidden option, and probably other neat tricks as well. Something that would make it even more useful for zsh completion would be to include information on the type of the argument when known. A zsh completer could then be programmed to do smart completion on the option value as well. (*) You can write a 'widget' and assign it to a key, and then when you use that key the completion widget (shell function) is called and could run the command with the hidden option to get the option info and generate the completion list. That's just the *easiest* way to integrate support for this into zsh completion. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4256 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8674] audioop: incorrect integer overflow checks
Tomas Hoger tho...@redhat.com added the comment: Do you have any Python examples that failed to trigger the overflow on your platform? No, I've not really tried to create some, as I found it while looking into similar checks added to rgbimg module (which is dead and removed upstream now) in the same commit r64114. Having another close look, I can reproduce crash with lin2lin: audioop.lin2lin(A*0x4001, 1, 4) ratecv may cause issues too. Other cases use for loop with multiplication product as an upper bound, so the integer overflow should be harmless in those case. is there something about the formats that audioop is dealing with that limits sizes to INT_MAX (rather than PY_SSIZE_T_MAX, for example)? I've started looking into this on oldish python 2.4, where PyString_FromStringAndSize accepts int size, rather than Py_ssize_t. Rest of the audioop code was using ints too. It's possible it is ok to more to size_t in current python version. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8674 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
