You can create your own serialization process, by providing some kind of 
serialize() method
 in a base class that would dump part of the object.

Let's say, the instance __dict__ dictionnary ?
this serialize method can then remove the attributes that starts with '_v_'
(that's what we do in Zope to avoid pickling some attribute)

That's a long discussion, you should look at the archives in the list.

But anyway, all attributes that starts with '__' are considered private 
to the class.
(ie: can't be reached by "instance.__attribute")

even though you can find it if you dig into instance.__dict__

make: circular dependency for Modules/signalmodule.o

[James Buchanan]

Hi group,

I'm preparing Python 2.4.2 for the upcoming Minix 3.x release, and I
have problems with make.  configure runs fine and creates the makefile,
but right at the end ends with an error about a circular dependency in
Modules/signalmodule.o.

I'm new to makefiles and makefile rules, so I can understand what this
means, but I don't know how I can fix this problem.  Looks like I'll
need to rewrite one or more makefile rules and during Minix builds add
some code to patch it up for those rules (as opposed to perhaps porting
a more capable `make` like gmake right now).

Can someone please help me make this problem go away?

Thanks!
James Buchanan

RE: Don't want to serialize a variable of object

Thanks a lot.

Actually you are right I would be trying same thing now.
Writing my own custom serializable for the object.

But everyone else who face the same problem would come up with their own
Serializable code.

Can't we plug something into cpickle So that it discards some variable from 
being serializable. Similar to __data for private variables. But on second 
thought that would be too much of change that I am asking.

Anyway thanks a lot.

See the pickle documentation. The example given in the documentation 
pickles a class while excluding one of its attributes.

http://www.python.org/doc/2.4.2/lib/pickle-example.html

> Another question:
>  Is there a concept of private variables?

'private variables' can mean either of two things: hiding the variables to 
prevent accidental naming conflicts in subclasses, or security to prevent 
malicious manipulation of a class's internal state.

Python provides the former (to a certain extent) when you give an attribute 
a name prefixed with a double underscore, but makes no attempt to provide 
the latter. Some other languages (such as C++) make no attempt to provide 
the former and a completely inadequate attempt at the latter.

In other words: Python has a concept of private variables, but it is 
different than in some other languages, and if you google past threads you 
can find endless discussions on the pro's and con's of the Python approach.

I didn't think unicode domain names existed.

It seems that they are in the pipeline:

``After much debate and many competing proposals, a system called 
  Internationalizing Domain Names in Applications (IDNA) was adopted as 
  the chosen standard, and is currently, as of 2005, in the process of 
  being rolled out.''

 - http://en.wikipedia.org/wiki/Internationalized_domain_names

It looks like the security issues are probably going to be dealt
with via technical fixes:

``On February 17, 2005, Mozilla developers announced that they would ship 
  their next versions of their software with IDN support still enabled, 
  but showing the punycode URLs instead, thus thwarting any attacks while 
  still allowing people to access websites on an IDN domain. This is a 
  change from the earlier plans to disable IDN entirely for the time 
  being.''

 - http://en.wikipedia.org/wiki/Internationalized_domain_names

Anyway, I'm inclined to suggest this is a DNS problem.  It would
apply to any format that allowed rendering of domain names using
the unicode character set they are intended to be displayed using.

Even without unicode, the "homograph attack" is still viable, due
to things like the "l"/"I" issue in many fonts - as pointed out on:

I mean property here. My aim was to create an ObserverProperty class

That's essentially what the IM folk did.

It seems quite possible that future email systems will evolve out of
existing IM ones.

Essentially, IM can do pretty-much everything email can these days, but 
the reverse is not true at all.

IM also seems more evolvable than email is managing to be.

About all email has going for it these days is an open format and a
large existing user base.

I don't have the exact numbers, and I'm pretty certain they'd be
confidential if I did, but I believe the factors you mention (browsers
completely lacking JS, and users turning JS off), *combined*, still
allow JS-rich interfaces to run for well over 95% of visitors to our
sites.  Maybe that's the key difference between the mindset of a
mathematician and that of an engineer -- I consider reaching over 95% of
visitors to be _quite good indeed_, while you appear to disagree because
of "WWW spirit" issues.  Is making a rapidly responsive site (not
requiring roundtrips for every interaction) a "compelling reason"?  It
seems to me that it is -- and why else would one use ANY Javascript,
after all?

My one issue with the JS/AJAX mania is that I really dislike JS as a
language, particularly when you take the mixed mongrel dialect that you
do need to reach all the various browsers and releases needed to make
that 95% goal.  But, alas, there is really no alternative!-(

If you think about it, much as you hate spammers you WANT them to have

The problem with IM is the various IM schemes don't talk to each
other.  You need a client that knows all the IM protocols.  But that
seems to be happening with Jabber and Trillian.

You have too much reliance on a central server. You have to trust the
relaying company.  I think it is time that nearly all mail was
routinely and transparently end to end encrypted, with the exception
of long enclosures that are explicitly marked not confidential.

You still have spam to a lesser extent and strangers just wanting to
talk.

A property is an 'overriding descriptor', AKA 'data descriptor', meaning
it "captures" assignments ('setattr' kinds of operations), as well as
accesses ('getattr' kinds), when used in a newstyle class.  If for some
reason you need an _instance_ to bypass the override, you'll need to set
that instance's class to one which has no overriding descriptor for that
attribute name.  A better design might be to use, instead of the builtin
type 'property', a different custom descriptor type that is specifically
designed for your purpose -- e.g., one with a method that instances can
call to add or remove themselves from the set of "instances overriding
this ``property''" and a weak-key dictionary (from the weakref module)
mapping such instances to get/set (or get/set/del, if you need to
specialize "attribute deletion" too) tuples of callables.

Easy -- in your class's body, just code:

  def getFoo(self): ...
  def setFoo(self, value): ...
  def delFoo(self): ...
  foo = property(getFoo, setFoo, delFoo, 'this is the foo')


Note that if you want subclasses to be able to customize behavior of foo
accesses by simple method overrides, you need to program some "hooks"
(an extra level of indirection, if you will).

Without parentheses after it, getMember is a method.  The difference
between a method object and an integer object (which is what member
itself is in your example) are many indeed, so your question is very
strange.  You cannot call an integer, you cannot divide methods, etc.

How to make command history persistent?

[vbfoobar]

Hello,

My question is:
  Is there an easy mean to make Python "command history"
  persistent across interpreter invokations?

PS:
  In the case the question above is not clear, I rephrase
  it below verbosely...
  When I work from the Python prompt, I enjoy features
  like command line editing and searching/recalling
  previous lines of code from the history.
  (This is similar to working from a Unix shell prompt.)
But I would like, in addition, be able to keep the history
  from one session to another (when I quit Python, the history
  is lost, but I would like to retrieve it each time In
  invoke again Python interactively).

Thanks

I see it's clear how to modify the behaviour of the descriptor instance, but is

 x = ObserverProperty('x')

a=A()

yup, but unfortunately, it's a bug at the windows level, not in Python.  from 
what
I can tell, the problem is that cmd.exe cannot parse the command string it's 
given
by the C-level system() call.

possible workarounds:

1. get rid of the quotes around the command name:

result = os.system('pythonbugtest.exe "test"')

2. add an extra quote (!) before the quoted command name:

result = os.system('""pythonbugtest.exe" "test"')

3. use os.spawn or the subprocess module instead.

And if companies are allowed to behave this way (because of your

Showing companies that you don't excuse such behavior would include not
buying there products, using other products, whatever. To say that they

Sorry, I didn't express myself clear to you. I mean:
b = A().getMember()
c = A().member
what's the difference between b and c? If they are the same, what's the
difference in the two way to get the value besides the style.

Bloodhound.Exploit.49 trojan found in MIMEBase.pyc

[Alex Hunsley]

Symantec antivirus has apparently picked up a virus in my Python 2.4 
(under cygwin):

Scan type:  Scheduled Scan
Event:  Threat Found!
Threat: Bloodhound.Exploit.49
File:  C:\cygwin\lib\python2.4\email\MIMEBase.pyc
Location:  Quarantine
Action taken:  Quarantine succeeded


There's info to be found on various pages, but it's a pretty terse 
explanation:
http://secunia.com/virus_information/22534/bloodhound.exploit.49/

Has anyone had this also? Is it perhaps a false positive?

I think MS obligation to its shareholders to maximise profits, does seem to 
make them cross the line quite frequently. Because of the slow legal process it 
seems that it's more profitable to do so.
A lot of these were however settled out of court, so technically, in a lot of 
them MS was not proven to have crossed the line, it does show a certain pattern 
though, some examples for googling "Microsoft lawsuit":
- 1982 Microsoft vs Seattle Computer Products, settled out of court.
- 1982 Microsoft vs Digital Research, DR won.
- 1985 Microsoft vs Apple, settled by Apple leasing MS access to the MacOS code.
- 1988-1998 Microsoft vs Apple, settled out of court, MS buys $150 mil Apple 
stock
- 1989 Microsoft vs DEC, settled out of court, MS paid $150 mil
- 1994 Microsoft vs Stac Electronics, MS lost, paid $84 mil
- 1996 Microsoft vs Novell/Caldera, settled out of court, MS paid $200 mil
- 1998-2002 Microsoft vs DOJ&20 states, MS lost, MS ordered to split up 
overturned in appeal.
- 2003 Microsoft vs Time-warner, settled out of court, MS pays $750 mil
- 2004 Microsoft vs EU, MS fined $613 mil
- 2004 Microsoft vs Sun, settled out of court, MS pays $700 mil

these guys also have a list, but it contains very few details:
http://www.theinquirer.net/?article=24621
They compute a total of over 9 billion in fines/settlements over the 30 year 
history of Microsoft.
 
To me it seems that MS finds it more profitable to do cross the line, and just 
pay the fines afterwards. I find it a real flaw in the corporate legal system 
that this is a valid way of doing business. That's a whole different topic 
though.

html parser?

Hi *,

is there a html parser available, which could i.e. extract all links from a

"""

and return a set of dicts like that:
"""

unittest of file-reading function

[Helge Stenstroem]

Say I have a function

def f(filename):
result = openFileAndProcessContents(filename)
return result

Can that function be unit tested without having a real file as input?
Something along the lines of

import unittest
class tests(unittest.TestCase):
def test1(self):
fileContents = "bla bla bla\nmore bla bla bla"
???   # make f read this string instead of opening a file
expected = expectedResult
result = f(filename)
self.assertEqual(result, expected)

One possibility would be to make the unit test write to a temporary
file. Are there better alternatives?

Second form is better because it makes it easier to refactor.

Like, at first A had a direct access to the member member. But later you 
want to control the access to it. So you change it into a property and 
you don't need to change client code.

ANN: ConfigObj 4.0.0 Final and Pythonutils 0.2.3

[Fuzzyman]

ConfigObj 4.0.0 final and Pythonutils 0.2.3 have just hit the streets.

http://www.voidspace.org.uk/python/configobj.html
http://www.voidspace.org.uk/python/pythonutils.html

They are both pure Python modules - the source distributions include
full documentation, which is also online.

What's New ?


ConfigObj 4.0.0 final has two bugfixes.
Using ``setdefault`` to create a new section would return a reference
to the dictionary you passed in - not the new section.
Also fixed a trivial bug in ``write`` (wouldn't have affected anyone).

Pythonutils 0.2.3 is updated to include the ConfigObj 4.0.0 final and
cgiutils 0.3.3

ConfigObj is now marked stable. (But caveat emptor :-)

What is ConfigObj ?
===

ConfigObj is a simple but powerful config file reader and writer: an
*ini file round tripper*. Its main feature is that it is very easy to
use, with a straightforward programmer's interface and a simple syntax
for config files. It has lots of other features though :

* Nested sections (subsections), to any level
* List values
* Multiple line values
* String interpolation (substitution)
* Integrated with a powerful validation system

- including automatic type checking/conversion
- repeated sections
- and allowing default values

* All comments in the file are preserved
* The order of keys/sections is preserved
* No external dependencies

What is Pythonutils ?
=

The Voidspace Pythonutils package is a simple way of installing the
Voidspace collection of modules. Several of the Voidspace Projects
depend on these modules. They are also useful in their own right of
course. They are primarily general utility modules that simplify common
programming tasks in Python.

These are currently :

* ConfigObj - simple config file handling
* validate - validation and type conversion system
* listquote - string to list conversion
* StandOut - simple logging and output control object
* pathutils - for working with paths and files
* cgiutils - cgi helpers (and functions for sending emails etc)
* urlpath - functions for handling URLs
* odict - Ordered Dictionary Class

All the best,

If getMember's body is nothing but a 'return self.member', then there is
no difference -- 'assert b is c'.

What is the difference between:

x = 2

and 

y = 2+2-2*2/2

???  Answer: in terms of final results, no difference.  On the other
hand, the second approach does a lot of obviously useless and intricate
computation, so it's a sheer waste of time and effort.

Exactly the same answer applies to your question -- obtaining the
.member attribute "indirectly", by calling a method that returns it,
does some obviously useless and moderately intricate computation, which
in some ways is a waste of (some) time and effort.  That's all!

The problem here is that Python's parse trees are of non-trivial ugliness.

A page on the compiler.ast module:
http://docs.python.org/lib/node792.html

it is, in fact, perfectly possible to write yourself a pre-processor for 
your particular application.  You may have to fiddle with the token you 
want for notation depending on how the AST fleshes out (% is used by at 
least a couple of things, after all).  My cursory familiarity with 
python grammar suggests to me that this particular choice of token could 
be a problem.

I would say try it and see.  Keep in mind though that since Python's AST 
is not a trivial matter like it is in Lisp and the like that doing 
metaprogramming of this sort probably falls into the category of black 
magic unless it turns out to be very trivial.

Another option is to define your own tiny class that will override the 
__mult__ method so that you can simply do:

A * B

Which may not be what you want.

It might also make your code more readable. I would like "A dot B", but even

A |dot| B

where dot was an object which had the OR operator for left and right

I guess you could hack something together along the same lines. I

The simplest approach is to use a StringIO.  Often that will require 
passing a "file" object to the routine instead of a file *name*, but 
often that's better anyway (decouples file management and parsing).

Another approach is to create a "mock file" object.  Depending on your 
needs, this can be a very simple or a very complex thing to do.  I can 
offer more detail/suggestions here if you need.

Yes, I see what you mean, it is pretty confusing. It almost looks like
a function that multiplies two matrices and returns the result. 

Have you tried coming up with better names for your arguments than A and
B? Many people find that using self-documenting variable names helps make

If you can refactor openFileAndProcessContents() so it looks like this:
def openFileAndProcessContents(filename):
  data = open(filename).read()
  processContents(data)

then you can write your tests against processContents() and just pass it a 
string with the test data.

I usually have a set of test files as part of my project that I can pass to 
functions like this.

I'm not speaking theroetically. My company (though not me personally) 
creates browser-based UIs, and one of the biggest expenses has been dealing 
with IE rendering bugs   Given the market share of IE, the fact that 
something should work, and even does work in Firefox, Opera, etc, is 
irrelevant.  If it breaks IE, we can't use it.

When we've had similar issues with C++ compilers, patches have usually been 
forthcoming, or perhaps optimization has to be turned off on a few source 
files.  In a few areas, though, the solution has been "Don't do that", and 
again, the fact that the standard supports it is irrelevant.

The thing is that I have in ProgramB a class derived from
threading.Thread, that runs a TCPServer, listening to a port on local
ip address.

As you surely know, you have to specify certain parameters when
instantiating the tcpserver:

SocketServer.TCPServer(server_address, RequestHandlerClass)
where server_address is a tuple (ip,port)
ip has to be one of three modes of values (If I remember well):

1. A null string ''
   Listens on all IP local address

2. A string containing the local IP address where you want it to listen
   Listens only in the specified local IP address

3. A string containing "localhost".
   Listens only for connections from "localhost".

Here comes the problem:
When you specify the case number 2, the IP must be valid for the
computer where the program runs, otherwise, it raises an exception
saying that "Can't assign requested address".
The TCPServer class, defined in a module, is ran (instantiatedly) from
the main program through a started thread. The thread also is in the
same module as TCPServer class.
It looks like (it's much more code than this. If you want the whole
code, tell me):

MainProgram.py
...
SrvrTCP = module.ThreadedTCPServer(ip,port)
SrvrTCP.start()
#Here, I want to know if the TCPServer started well.
...


module.py
...
class ThreadedTCPServer(threading.Thread):

def __init__(self, ip,port):
threading.Thread.__init__(self)
self.ip= ip
self.port= port

def run(self):
TCPServer((self.ip,self.port)) #Here, if the self.ip is
invalid, it raises an exception.

It is possible to decorate a method in a way that it seems like
property() respects overridden methods. The decorator cares
polymorphism and accesses the right method.

def overridable(f):
def __wrap_func(self,*args,**kwd):
func = getattr(self.__class__,f.func_name)
if func.func_name == "__wrap_func":
return f(self,*args,**kwd)
else:
return func(self,*args,**kwd)
return __wrap_func


class A(object):
def __init__(self, x):
self._x = x

@overridable
def get_x(self):
return self._x

x = property(get_x)

class B(A):

def get_x(self):
return self._x**2

class C(B):pass

You snipped the bits that provide the context showing that here Peter and I
were talking about versions of SunOS, not MS-DOS.

I too don't recall an MS-DOS 3.4.  The Victor/Sirius version I mentioned
was definitely 3.10 (three point ten)--the version byte was hex 030A.
Perhaps the gap in sequencing was introduced to separate the versions
for IBM-compatible machines from the versions for non-IBM-compatible
machines.

Oh? So you'd consider an SMTP/IMAP/POP/DNS/NFS/etc server that
rejected 5% of the systems connecting to be _quite good indeed_? I
think I'm glad that the internet wasn't built by people who agreed
with that.

If you know what you're doing, you can have the best of both worlds
for a lot of web applications. Yes, it won't be as rich or functional
for the five percent who worry about security (or whatever), but it'll
still work. And yes, you can't do it for every application. For those,
anyone vaguely competent will add a warning.

What surprises me is that marketing types will accept turning away -
what's the current internet user base? 200 million? - 10 million
potential customers without a complaint. Or maybe they just don't get
told that that's what's going on.

Been there, done that, threw out the T-shirt as to ugly to wear.

Yes, you have to work around bugs in the popular browsers. That hasn't
changed since the first published specs showed up. That doesn't mean
you throw out the standards and only support a trivial set of
browsers. That means you restrict yourself to a subset of the
standard, or - better - detect the deficiency and fail soft, the same
as you would do when you get a visit from someone who's disabled some
feature you want to use. In extreme cases, you wind up implementing
something twice: once for busted-but-popular browsers, and once for
people using browsers written by developers who read specifications.

Obviously we all agree the effort to support both is significant.  The 
question is not so much "do we turn away 5%" as "do we use the effort we 
do have to provide a better experience for the 95%, or to provide a 
slightly worse experience for the 95%, and an ok experience for the 5%".

If you're a business, the question then becomes, does the incrementally 
better experience produce a higher conversion rate (i.e. more sales), in 
which case it may well be a better investment to focus there and ignore 
the 5%.  It's but one perspective, but depending on your goals, can be a 
reasonable choice to make.

There wàs indeed a version 3.4, but I don't know whether this was
MS-DOS.  IBM did have a PC-DOS 3.4 at one stage, where it offered the
purchaser of the PS/2 series computers the choice between DOS 3.4 and
DOS 4.00.

However, Peter was of course not talking of DOS. ;-)

Re: Yes, this is a python question, and a serious one at that (moving to Win XP)

[Chris Lambacher]

The shell that comes with MSys (from the MinGW guys). Is pretty good, although
it does have a bit of a problem with stdout output before a process exits, ie
it will hold back output until the process exits.

As a bonus, the file system is a little more sane, and if you are interested
in compiling software that is not open source, you are not tied to the Cygwin
DLL which is GPLed.

I have given up on Cygwin in favour of the tools that come with MSys because
they seem slightly better suited to the windows environment.

This is so true, although I don't expect those people relentlessly

to necessarily make an accessible Web site for those people who, for
whatever reason, can't use the mountains of JavaScript that perform the
fancy fades and colour flashes that seem "de rigeur" in their "Web 2.0"
applications.

Here's an interesting perspective from outside the "AJAX clique":

In firms where marketing has lots of power, they may indeed well decide
to pursue those "10 millions" by demanding an expenditure of effort
that's totally out of proportion (to the detriment of the other "190
millions", of course, since there IS a finite amount of development
resources to allocate).  Maybe that's part of the explanation for the
outstanding success of some enterprises founded by engineers, led by
engineers, and staffed overwhelmingly with engineers, competing with
other firms where marketing wield power...?

What features are you looking for.  I think most Vim users just add what 
they want to Vim.

Here's what I use to launch a script and capture the output into a read 
only panel.  I think it may still needs a little fine tuning.  This is 
on windows, but it should work on linux with some minor changes.

Cheers,
Ron


Add this to your python.vim file in your ftplugin directory.

" Run a python script and get the output into a window.
set switchbuf=useopen
function! RunPython(rmode)
 if a:rmode=='wnd'
 " Run in python shell and capture the
 "   output to a vim buffer window.
 execute "w!"
 if bufnr("python_stdout") >0
 exe "sb python_stdout"
 else
 exe 'split python_stdout'
 endif
 setlocal noswapfile
 set buftype=nofile
 setlocal modifiable
 normal ggdG
 silent! exe 'r!python #'
 setlocal nomodified
 set filetype=txt
 normal 1G
 elseif a:rmode=='ext'
 " Execute script in python shell
 execute "w!"
 !start python -i %
 else
 " Open an interactive shell
 !start python
 endif
endfunction

" Add keymap to run and open console
map  :call RunPython("wnd")
map  :call RunPython("ext")

Have a main function that you pass the arguments into.  This entry on Guido's

Re: PEP: Adding decorators for everything

[Diez B. Roggisch]

> @GuardedClass
> class Foo:

The functionality can be done using a meta-class, in a similarily 
declarative way.

These are tricky, as the implicitly change the nature of the values - 
they become properties. And the decorator protocol has to change, as the 
passed value is obviously not a callable, but a random value. So in the 
end, you could simply do something like this:


@Const(3.24)
def PI(self):
pass

with Const basically ignoring its callable-argument and simply returning 
a get-only-property. I have to admit that I was tempted to use such a 
thingy just the other day. But it is not exactly nice, and using

PI = Const(3.14) as you suggested is even more pleasing.

Additionally, the first @Transient-decorator can't be done that way, as 
the decorator protocol doesn't know about the _name_ a thing is bound to 
later. And you'd need that to actually set up e.g. __getstate__ operate 
properly.

And it doesn't mkae much sense anyway, as "a" is a class variable, not a 
instance variable.

So - I'm not very much in favour of these enhancements.

Re: Vim capable IDE?

[Chris Lambacher]

I would second that.  I use Vim for editing.  I find I don't need an IDE (not
even for C/C++).  Vim does everything I need.  If I want a debugger I will use
the shell debugger.  Most other things can be added to Vim, though I tend to
run with very few plugins.

Re: html parser?

[HTMLParser example]

I've used SGMLParser with some success before, although the SAX-style
processing is objectionable to many people. One alternative is to use
libxml2dom [1] and to parse documents as HTML:

import libxml2dom, urllib
url = 'http://www.python.org'
doc = libxml2dom.parse(urllib.urlopen(url), html=1)
anchors = doc.xpath("//a")

Currently, the parseURI function in libxml2dom doesn't do HTML parsing,
mostly because I haven't yet figured out what combination of parsing
options have to be set to make it happen, but a combination of urllib
and libxml2dom should perform adequately. In the above example, you'd
process the nodes in the anchors list to get the desired results.

Well, what he said was

  "During my service in the United States Congress, I took the
   initiative in creating the Internet."

What you say he did is what he actually did, but what he said gives a
different impression. I don't think he's careless or stupid, so I
think he said that in order to create the impression in the minds of
the people listening to the interview that he's responsible for the
internet. 

That's just what politicians do, regardless of party affiliation.

Using scons zip builder to create zip

[Chris Becker]

What I am looking for is how to call the builder so that it does not
recurse directories and does not add paths:

zipFile = env.Zip(outputFile, sourcePath)

I seen something in the docs about ZIPFLAGS env var, but there is no
documentation on what the options are.

Re: Web based applications are possible with wxPython?

[Brett Hoerner]

I don't think this is possible, unless I am grossly misunderstanding.

For the web, pretty much every "UI" is build with some variation of
HTML (XHTML is the new standard) with JavaScript thrown in for fancy
GUI-like interfaces.

You can't use OS-native widgets in the web browser, no.
