Re: Is this the proper way to use a class method?

But if I make the super call as super().move(), how does that work? The move method in the superclass takes an argument, and if I just do super().move(), isn't it the subclass that's getting passed to it? The self that gets passed into the superclass.move() or the subclass.move() is the exact same object in either case. There is no up-casting (or any casting at all, for that matter) in Python. How does the superclass move method know what 'self' is if it doesn't get passed to it as I did originally? super() called without arguments is equivalent to super(class this method was defined in, self) -- it collects the value of self from the current stack frame. So self is able to be passed in because the super object implicitly knows what self is. Cheers, Ian -- http://mail.python.org/mailman/listinfo/python-list

Python - CGI-BIN - Apache Timeout Problem
Hello List, Would appreciate some insight/help, ran out of ideas... BRIEF OVERVIEW: I am trying to create a simple webserver gui wrapper for a set of scripts I developed to test some of our firewalls here at Cisco. Being that the total amount of engineer that will ever probably use this is 4 people and my limited python experience I just decided to do a quick cgi-bin solution. I control the machine with the webserver on em0 where I do my fw testing on em1/em2. Browser goes to http://webserver/main.py- main.py executes a script-tests.py -test.py imports my engine v6tester_main.py which is a series of functions I wrote. tests.py kicks of whatever test main.py wanted. THE PROBLEM: When I execute the scripts from the command line (#python main.py) it generates it fine (albeit slowly), it prints all the html code out including the script. The 'core' part of the script dumbed down to the lowest level is- proc = subprocess.Popen(['/usr/local/bin/python', 'tests.py'], stdout=subprocess.PIPE) output = proc.stdout.read() print output proc.stdout.close() When I open main.py and execute the script it just hangs... it seems to execute the script (I see pcap fires on the interface that I am testing on the firewall) but its not executing correctly... or loading the entire webpage...the webpage keeps chugging along and eventually gives me an error timeout. I know it's not a permissions issue or setup issue b/c I did a proof of concept where I just fired one simple pcap and it works fine (reported back just like it would if I ran it on the command line).. it has something to do with either the amount of prints out the script is doing, or the timing. I see no problems except the timeout (nothing in logs: /var/log/http-error.log). My script takes about 8 secounds to run. It does use threading but I wouldn't think that would mess it up. BTW: I posted here if this helps anyone: http://stackoverflow.com/questions/9524758/cgi-bin-timing-timeout-on-fre ebsd-apache22 Thanks in advance for any ideas. I can include the whole main.py if that would help. Sean Cavanaugh Cisco Systems -- http://mail.python.org/mailman/listinfo/python-list

RE: Python - CGI-BIN - Apache Timeout Problem
Hey All, So maybe this part is important (after doing some troubleshooting) hopefully not everyone has beers in hand already since its Friday :-) The way the code works if you want to send through the firewall (i.e. SERVER-FIREWALL-SERVER) I split the process into two threads. One is listening on the egress, then I send on the ingress. The main waits until the thread finishes (it times out after 2 seconds). I had to do this b/c scapy (the library I used) won't let me send pcaps while I receive them. This lets me see packets on both sides (i.e. did that sort of internet traffic go through the firewall).

Re: Is it necessary to call Tk() when writing a GUI app with Tkinter?
After that, you can nest as many frames, toplevels, and blah widgets under that root window as you so desire. Actually you don't even need a frame, you can pack widgets directly into a Toplevel or Tk widget. This is interesting. I completely understand your point about always calling (and using) the instance of Tk as the root. Given that, what is the point of creating a Frame object at all? I tried NOT doing it, like you said, and it seemed to work fine with my simple example. But is there a benefit to using a Frame object to group the widgets together? Or is it cleaner to just use the Tk object? -- http://mail.python.org/mailman/listinfo/python-list
A possible change to decimal.Decimal?
HISTORY:
In using python 2.7.2 for awhile on a web project (apache/wsgi web.py), I
discovered a problem in using decimal.Decimal. A short search revealed that
many other people have been having the problem as well, in their own
apache/wsgi implementations (django, mostly), but I found no real solutions
among the posts I read. So I did some experimentation of my own.
The following code will break unexpectedly on standard python2.7 (and earlier)
because of the way that isinstance fails after reload() (which is called by
both of the above web frameworks).
This is the error: TypeError(Cannot convert %r to Decimal % value)
THE TEST CODE
import decimal
from decimal import Decimal
#this works
Decimal(Decimal())
reload(decimal)
#this fails before patching, but works fine afterwards
Decimal(Decimal())
THE SOLUTION:
So, looking into decimal.py I discovered lots if statements using isinstance,
and have slightly rearranged the code inside __new__() to mostly remove their
use, and for my purposes totally fixes the problem within wsgi.
I am not an official python dev, so would appreciate it if someone who *IS*
could just look this over, improve it if necessary, and get it (or some
variation) submitted into the library.

Re: A possible change to decimal.Decimal?
The problem with that though is: I am not the one calling reload(). That is actually being called for me by web.py (or django, or some other framework, take your pick). More than that, I believe it's called (or caused, anyway) by something happening in WSGI under apache. (And I don't really want to start digging around in there either) The patch in this case is very limited in scope, and all it inflicts on the subject code inside of decimal.Decimal.__new__(), is better programming practices. --jeff On Fri, Mar 2, 2012 at 5:49 PM, Ethan Furman et...@stoneleaf.us wrote: Jeff Beardsley wrote: HISTORY: In using python 2.7.2 for awhile on a web project (apache/wsgi web.py), I discovered a problem in using decimal.Decimal.

Interestiong idea. Generators are fully supported so I could do this now.
So gens would have to be allowed absolutely everywhere lists are allowed (is

No, the former. Most of the time you never really use a full, naked list

I strongly suggest the standard (in math anyway) syntax for set notation. It
shouldn't be hard to parse whether code syntax is referring to a set vs. dict.
--Functions that return multiple, but unique, values should return a

This is something that still hasn't really been implemented in PythonV3.
--Dict should inherit from Set.
Also cool (I feel like the credits of Holy Grail saying Also wik).
An alternative is to create a named association type, similar to the ABC
programming language, denoted by the colon. name: []. A dict then would
simply be a set of these. Having a compound type would come in handy in
several other ways too.
--With prothon's immutability bit and other considerations, does the
language need both tuples AND lists?
I like this a lot. Tuples are already implemented internally as lists.
I think, in fact, that the object model could be more unified. Under such a
new object model, the worries about having a full library becomes rather
pointless, as the new model will require a revamping of everything.
More like a few dollars. This is really good stuff. Can I talk you into

I take it from the ABC language. The thing that's relevant (and apropos to Paul Rubin's objection), is that when unifying models, you have to decide where the decimal point is from which all the different dimensions that the language is encoding and silently tracking can pivot around. The : of a compound is a sort of decimal point. Then the task is finding a formalism in which to define and incorporate all the relavent dimensions into one.

[issue14173] PyOS_FiniInterupts leaves signal.getsignal segfaulty
New submission from Ferringb ferri...@gmail.com: During Py_Finalize (pythonrun.c), it does the following: 1) suppress signal handling PyOs_FiniInterupts 2) clear caches 3) force gc collection; first for objects, then via wiping modules. The problem is that for unix OSs, Modules/signal.c's PyOs_FiniInterrupts leaves itself in a state where its internal Handlers are effectively reset to NULL, except the various functions don't properly handle that scenario. Attached is a test case demonstrating it; it segfaults on every python version I've tested (2.4-3.2; haven't tried 3.3). Since this *only* occurs during the final gc sweep when modules are destroyed, its a bit of a pain in the ass to detect that we're in that scenario, and that we must not touch signal.getsignal lest it segfault the interp. That said, def _SignalModuleUsable(): try: signal.signal(signal.SIGUSR1, signal.signal(signal.SIGUSR1, some_handler)) return True except (TypeError, AttributeError, SystemError): # we were invoked in a module cleanup context. return False does manage to poke the api just right so that it can be detected w/out segfaulting the interp. Finally, note that while folks could point at __del__... its not really at fault. Doing a proper weakref.ref finalizer can trigger the same- the fault is signal.c's PyOs_FiniInterrupts leaving the signal module in a bad state. For the testcase, I used __del__ just because it was quicker/less code to do so. -- components: Interpreter Core files: test.py messages: 154758 nosy: ferringb priority: normal severity: normal status: open title: PyOS_FiniInterupts leaves signal.getsignal segfaulty type: crash versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2 Added file: http://bugs.python.org/file24703/test.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

c.getresponse().getheaders()
[('Date', 'Fri, 02 Mar 2012 16:56:40 GMT'), ('Server', 'Apache'),
('Set-Cookie', 'test_cookie1=foobar; expires=Fri, 02-Mar-2012 16:57:40 GMT'),

As you can see, in 2.7.2 HTTPResponse.getheaders() in 2.7.2 joins headers with
the same name by , . In 3.2.2, the headers are kept separate and two or more
2-tuples.
This causes problems if you convert the list of 2-tuples to a dict, because the
keys collide (causing all but one of the values associated the non-unique keys
to be overwritten). It looks like this problem is caused by using the email
header parser (which keeps the keys and values as separate 2-tuples). In Python
2.7.2, the HTTPMessage.addheader(...) function does the comma-separating.
Is this API change intentional? Should HTTPResponse.getheaders() comma-separate
the values like the HTTPResponse.getheader(...) function (in both 2.7.2 and
3.2.2)?

[issue14144] urllib2 HTTPRedirectHandler not forwarding POST data in redirect
Jay Deiman ad...@splitstreams.com added the comment: Senthil, The HTTPRedirectHandler is already breaking RFC2616 by it's own admission in the code comments (from the source): # Strictly (according to RFC 2616), 301 or 302 in response # to a POST MUST NOT cause a redirection without confirmation # from the user (of urllib2, in this case). In practice, # essentially all clients do redirect in this case, so we # do the same. # be conciliant with URIs containing a space I can definitely understand the issue with changing the default behavior to redirect the POST data. However, an added option which leaves the current behavior as the default shouldn't hurt. I'm submitting a new patch file (urllib2.py.redirect_option.patch), which will do exactly that. -- Added file: http://bugs.python.org/file24711/urllib2.py.redirect_option.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14144 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Do you know anything about spaces in the button text causing the addition of
{bra ces}? I would prefer not to have to use an underscore in Hello_World.
I fixed the long line and also updated pack calls pass options by name instead
of a dict.

[issue14176] Fix unicode literals (for PEP 414)
Jean-Michel Fauth wxjmfa...@gmail.com added the comment: I deliberately hid the information about the used interactive interpreter; just to show you the experience of new Python user. (This is what I'm showing to potential Python devs who are interested in this tool; I know Python and use it since v. 1.5.6 as a non computer scientist). The interactive interpreter was: Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32 Type copyright, credits or license() for more information. In that precise case, it was Windws 7 Pro (Windows 7 Professionnel, in French because of a Swiss French version) and IDLE is just the IDLE an end user see after a fresh installation. I can ensure you, such a behaviour exists / existed on all Windows versions I used (from Win98, win2000, ...) with all the Python 2 versions since the unicode introduction. The technical reasons/aspects: sys.defaultencoding, non iso-8859-1 chars [#], *non working unicode literals*, sys.stdout.encoding = 'cp1252' and so on. [#] For those who do not know, one can not write text in French with Latin-1. Please do not take my aggressive (I recognize it), but sometimes necessary message badly. IDLE is not the cause, I use here IDLE to show as an example the disaster of code containing *unicode literals*. I'm not really happy to see this mess again in Py3.3 [†]; the key point beeing *unicode literals*. The Pandora's box is opened. [†] In fact, I will somehow never see or suffer from it.
