ANN: A STOMP messaging broker in pure Python (GPLv3)
This is the first announcement of a release of Sprinkle, a messaging broker written in Python. http://www.thuswise.org/sprinkle/index.html Sprinkle implements the STOMP protocol http://stomp.codehaus.org/ Sprinkle is very simple and lightweight. I believe it is fully functional, but I need help testing it so I can make it suitable for an enterprise environment. In this early phase, you can get Sprinkle as a development snapshot: sprinkle-2007-07-01. Asynchronous messaging is receiving renewed interest from developers. Let's give Python a simple, effective, and trusted messaging solution. The code is distributed under version 3 of the GPL, and runs on Unix- like platforms. Python 2.3.4 or later is required. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
ANNOUNCE: PyGTK 2.10.5
I am pleased to announce the stable version 2.10.5 of the Python bindings for GTK+. The new release is available from ftp.gnome.org and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.10/ Blurb: GTK+ is a toolkit for developing graphical applications that run on systems such as Linux, Windows and MacOS X. It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full features applications. What's new since 2.10.4 ? - Do access private GtkTooltip member tips_data_list, fixes build against Gtk+ 2.11.x (Johan) - Allow None to gtk_rc_get_style_by_paths (Mariano Suarez-Alvarez) - Fix defs file inconsistencies (Andrew Cowie) - Documentation build fixes (Richard Hult) - Code generator improvements (Tim Evans, Gustavo) - Include atk-types.defs when building using distutils, so gtk.Accessible is available on win32 PyGTK requires GTK+ = 2.8.0 and Python = 2.3.5 to build. Bug reports, as always, should go to Bugzilla; check out http://pygtk.org/developer.html and http://pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK. -- Johan Dahlin [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
itools 0.16.1 released
itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalogitools.i18n itools.tmx itools.cmsitools.ical itools.uri itools.csvitools.odf itools.vfs itools.datatypes itools.pdf itools.web itools.gettextitools.rest itools.workflow itools.handlers itools.rss itools.xhtml itools.html itools.schemas itools.xliff itools.http itools.stl itools.xml This is (mostly) a bug fix release: - The command line tool rsync is not required anymore. - Indexing of XML documents (like web pages) works again. - Now itools.web supports X_FORWARDED_PROTO, what makes possible to deploy web applications behind Apache (or another web server) using the HTTPS protocol. - Now itools.xml is able to serialize documents with CDATA sections. - In itools.stl the repeat variables repeat/x/index, repeat/x/start and repeat/x/end work again. - The method set_handler works now when the container is a virtual handler. But most changes are in the itools.cms package: - The Quick Start is updated now, the icms-make-package -t quickstart command works again. - The new method get_object has been added to the itools.cms API. - An important bug has been fixed in the itools.cms database, where the incorrect usage of mkstemp made sometimes a transaction to fail because all files descriptors were used. - Now we correctly unindex the content of a folder when it is removed. - There are various fixes and improvements to the Calendar and Wiki objects. - The script icms-update has been improved in different ways. Most important, now it is possible to upgrade an itools.cms instance directly from 0.14 to 0.16 (no need to go through 0.15).

Re: ['a', 'b'][True] results 'b' But how?
In this case, [True] and [False] are not lists, rather you're accessing the items of the list with the index True or False, as per the following example: a_list = ['a', 'b'] a_list[True] 'b' a_list[False] 'a' This happens because the __getitem__ method takes its argument (which in this case is True or False) and casts it into an integer: int(True) 1 int(False) 0 So thus it follows logically that since: a_list[1] 'b' a_list[0] 'a' a_list[True] and a_list[False] must be its first and zeroth indexed members, respectively.

Re: Memory leak issue with complex data structure
Alan Franzoni [EMAIL PROTECTED] writes: I have a serious leak issue; even though I clear all those sets and I delete all the references I can have to the current namespace, memory is not freed. Maybe the memory is freed (marked as available for further use by Python), just not released to the operating system.[1] To test against that, try to allocate more Python structures and see if they reuse the freed memory or if they allocate even more memory. Even better, run code like this: while 1: ... populate your data structures ... clear() If this causes Python to allocate more and more memory, it means you have a real leak. If not, it means that the GC is working fine, but it's not possible to release the memory to the OS.

Re: Tkinter toggle a Label Widget based on checkbutton value

Following is a tk code, which will display a checkbutton, and when
checkbox is
enabled, it will show the below present Label.
What I was trying is, when checkbox is enabled the Label should be shown
and
when checkbox is disabled, the window should look like before.
But, I am finding that once enabled (shown), its not
very-straightforward to
hide it from the window.
Any suggestions on how can i make this checkbutton effect.
1) Press Enable IP, the Label IP should be shown.
2) Toggle Enable IP (So that its unset). the Label IP should not be
shown.
#!/usr/bin/python
from Tkinter import *
root = Tk()
root.title('something')
x = StringVar()
def display():
if x.get():
ip = Label(root,text=IP:)
ip.grid(row=3,column=0)
proxy = Checkbutton(root, text=Enable IP:, variable =
x,onvalue=proxy,
offvalue=,command=display)
proxy.grid(row=2,column=0)
root.mainloop()
Wojciech gave a perfectly valid answer that'll work in all cases.
Here is another one, that you may or may not be able to use, which
consists in using the same Tkinter variable for your check-button's value
and your label's text:
--
from Tkinter import *
root = Tk()
labelString = StringVar()
b = Checkbutton(root, text=Enable IP:, variable=labelString,
onvalue='IP:', offvalue='')
b.grid(row=2, column=0)
Label(root, textvariable=labelString).grid(row=3, column=0)
root.mainloop()
--
This doesn't really make the label disappear when the check-button is
off, but simply sets its text to the empty string.

As far as I understand the issue, any Python process has a sort of main thread. When the main thread exits, the Python process will exit if there are only daemon threads around. If there are any non-daemon threads, the Python process will only exit after those threads are finished. Or, as the documentation says: The entire Python program exits when no active non-daemon threads are left. Kind regards, Benjamin -- http://mail.python.org/mailman/listinfo/python-list

Paul Rubin wrote: John Nagle [EMAIL PROTECTED] writes: This has been tried. Original KR C had non-enforced static typing. All struct pointers were equivalent. It wasn't pretty. It takes strict programmer discipline to make non-enforced static typing work. I've seen it work in an aerospace company, but the Python crowd probably doesn't want that level of engineering discipline. I think even enforced static types wouldn't cure what I see as the looseness in Python. There is not enough composability of small snippets of code. For example, the for statement clobbers its index variable and then leaks it to the outside of the loop. That may be more of a culprit than dynamic types. Perl and C++ both fix this with syntax like for (my $i in ...) ... (perl) or for (int i = 0; i n; i++) ... (C++, Java) making a temporary scope for the index variable. Python even leaks the index variable of list comprehensions (I've mostly stopped using them because of this), though that's a recognized wart and is due to be fixed. Wow, you really take non-pollution of the namespace seriously. I agree it's a wart, but it's one I have happily worked around since day one. Python would be helped a lot by some way to introduce temporary scopes. We had some discussion of this recently, concluding that there should be a compiler warning message if a variable in a temporary scope shadows one from a surrounding scope. Yeah, well the approach to scoping could really be improved, but if you keep your namespaces small it's not difficult to keep things straight. I have always been rather guarded in my approach to accessing non-local scopes because the coupling is rather less than obvious, and is subject to variation due to non-local changes. regards Steve -- Steve Holden+1 571 484 6266 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden --- Asciimercial -- Get on the web: Blog, lens and tag the Internet Many services currently offer free registration --- Thank You for Reading - -- http://mail.python.org/mailman/listinfo/python-list

Re-raising exceptions with modified message
What is the best way to re-raise any exception with a message
supplemented with additional information (e.g. line number in a
template)? Let's say for simplicity I just want to add sorry to every
exception message. My naive solution was this:
try:
...
except Exception, e:
raise e.__class__, str(e) + , sorry!
This works pretty well for most exceptions, e.g.
try:
... 1/0
... except Exception, e:
... raise e.__class__, str(e) + , sorry!
...
Traceback (most recent call last):
File stdin, line 4, in module
ZeroDivisionError: integer division or modulo by zero, sorry!
But it fails for some exceptions that cannot be instantiated with a
single string argument, like UnicodeDecodeError which gets converted
to a TypeError:
try:
... unicode('\xe4')
... except Exception, e:
... raise e.__class__, str(e) + , sorry!
...
Traceback (most recent call last):
File stdin, line 4, in module
TypeError: function takes exactly 5 arguments (1 given)
Another approach is using a wrapper Extension class:
class SorryEx(Exception):
def __init__(self, e):
self._e = e
def __getattr__(self, name):
return getattr(self._e, name)
def __str__(self):
return str(self._e) + , sorry!
try:
unicode('\xe4')
except Exception, e:
raise SorryEx(e)
But then I get the name of the wrapper class in the message:
__main__.SorryEx: 'ascii' codec can't decode byte 0xe4 in position 0:
ordinal not in range(128), sorry!
Yet another approach would be to replace the __str__ method of e, but
this does not work for new style Exceptions (Python 2.5).
Any suggestions?

You're reusing the same md dictionary over and over, appending the

and some examples, and news that it has been recently improved. But
where is the full, current documentation for the dict() constructor?
There's no dict.append or dict.add because a dict doesn't require
them. You insert keys via the normal indexing interface:
somedict[somekey] = somevalue.
Depending on which direction your mapping is, you may be interested in
the setdefault method.
The dict constructor is described in section 2.1, built in functions
(even though it's not a function anymore).
The other dict methods are described in section 3.8, mapping types.

Well, if you catch an exception and don't return quickly, you have to
consider not only the possibility that there could be some open files
left in the traceback, but also that there could be a large and now
useless data structures stored in the traceback.
Some people here have been arguing that all code should use with to
ensure that the files are closed. But this still wouldn't solve the
problem of the large data structures being left around for an
arbitrary amount of time.
I don't think anyone has suggested that. Let me be clear about *my*
position: When you need to ensure that a file has been closed by a
certain time, you need to be explicit about it. When you don't care,
just that it will be closed soonish then relying on normal object
lifetime calls is sufficient. This is true regardless of whether
object lifetimes are handled via refcount or via true garbage
collection. Relying on the specific semantics of refcounting to give
certain lifetimes is a logic error.
For example:
f = some_file() #maybe it's the file store for a database implementation
f.write('a bunch of stuff')
del f
#insert code that assumes f is closed.
This is the sort of code that I warn against writing.
f = some_file()
with f:
f.write(a bunch of stuff)
#insert code that assumes f is closed, but correctly this time
is better.
On the other hand,
f = some_file()
f.write(a bunch of stuff)
#insert code that doesn't care about the state of f
is also fine. It *remains* fine no matter what kind of object lifetime
policy we have. The very worst case is that the file will never be
closed. However, this is exactly the sort of guarantee that GC can't
make, just as it can't ensure that you won't run out of memory. That's
a general case argument about refcounting semantics vs GC semantics,
and there are benefits and disadvantages to both sides.
What I am arguing against are explicit assumptions based on implicit
behaviors. Those are always fragile, and doubly so when the implicit
behavior isn't guaranteed (and, in fact, is explicitly *not*
guaranteed, as with refcounting semantics).

While the intersection of two sets is well-defined, these two sets intersect is (surprisingly!) _not_ well-defined. Poppycock! It's perfectly well defined: two sets intersect if and only if their intersection is nonempty. That's certainly _a_ definition. I'm not a professional set theorist, but in 15-odd years of studying and teaching maths I've never come across mathematicians using intersect as a verb except as informal short-hand. I often say North Street and South Street don't intersect, but the intersection of sets A and B is empty. Just because I've never come across it doesn't mean it exists, so I'd be grateful for any reference to a technical definition, or even references to any mathematician using intersect as a verb in a vigorous, non-hand-waving way. Here's a link to get you started: http://www.google.com.au/search?q=define%3Aintersect There's absolutely no reason to single out the empty set for special treatment in this definition. But you can't avoid treating the empty set as special, because it _is_ special. You can only choose where to do so. For instance, do sets intersect with themselves? By my rule, every set intersects with itself, no exceptions. By your rule, every set intersects with itself, except for the empty set. The problem comes if we (perhaps naively) try to say that if a set A is a subset of set B, set A must intersect with B. Well of course false statements are going to cause problems. My statement is only false if we treat the empty set as special, which you've said we shouldn't do. By my rule: if A = B, then A and B intersect, no exceptions. By your rule: if A = B and A is not the empty set, then A and B intersect. (Not all intersecting sets are subsets, but all subsets are intersecting sets.) Not true. Can you give a counter-example, without treating the empty set as special? Of course if you exclude the empty set by definition, my statement is no longer true -- but that's begging the question of whether we should exclude the empty set or not. As a result, any proposed function or method that returns a True/False value for whether set A intersects with set B needs to define (and justify) what it means to say that two sets intersect when one or both are the empty set. Nope. There's one, obvious, correct definition, as given above. No need to mention the empty set at all. It is obvious, but whether it is correct or not depends on how you decide whether two things intersect or not. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list

deliberate versus os socket timeout
While messing about with some deliberate socket timeout code I got an
unexpected
timeout after 20 seconds when my code was doing socket.setdefaulttimeout(120).
Closer inspection revealed that this error in fact seemed to come from the os
(in this case windows xp).
By inspection of test cases the error.reason from the deliberate socket timeout
looks like
'timed out'
whereas the windows caused timeout error.reason looks like
'(10060 operation timed out)'
it would be nice to know if that is in fact true and whether there is any way
to
do the attribution of errors more sensibly.
Both of these seem to cause urllib2.URLError and presumably appear somewhere in
the socket code.
It might be nice if the deliberate timeout could be something like 'timed out
deliberately after xxx seconds'.
More importantly is there anything I can do to avoid these wrong os inspired
timeouts? I'm just using urllib2 to read from a remote site inside of a cgi
script. I'm not sure it's a big problem, but I have no idea what could cause it.
The code I'm using is based on one of jjlee's recipes
def httpGet(self):
import urllib2, socket
from xml.sax.saxutils import escape
oto = socket.getdefaulttimeout()
try:
socket.setdefaulttimeout(self.timeout)
self.url = url = self.makeUrl(self.params)
try:

But that's not enough information for me to use. Also, the doc says
basically csv has dialects, but doesn't even enumerate them. Where is
the real documentation?
Also, when I do a print of row, it comes out as:
['12345', 'ET']
But there are no quotes around the number in the file. Why is Python
making it a string?

I don't think anyone has suggested that. Let me be clear about *my*
position: When you need to ensure that a file has been closed by a
certain time, you need to be explicit about it. When you don't care,
just that it will be closed soonish then relying on normal object
lifetime calls is sufficient. This is true regardless of whether
object lifetimes are handled via refcount or via true garbage
collection. Relying on the specific semantics of refcounting to give
certain lifetimes is a logic error.
For example:
f = some_file() #maybe it's the file store for a database implementation
f.write('a bunch of stuff')
del f
#insert code that assumes f is closed.
This is the sort of code that I warn against writing.
f = some_file()
with f:
f.write(a bunch of stuff)
#insert code that assumes f is closed, but correctly this time
is better.
This has raised a few questions in my mind. So, here's my newbie
question based off this.
Is this:
f = open(xyz)
f.write(wheee)
f.close()
# Assume file is closed properly.
as safe as your code:
f = some_file()
with f:
f.write(a bunch of stuff)
#insert code that assumes f is closed, but correctly this time
Thanks!

In addition to Chris's answer, the csv module can read and write
dictionaries directly. Look up csv.DictReader and csv.DictWriter.
DictReader gives one dict per row, with field names as keys. The OP is more
likely to want
dict(csv.reader(open(some.csv, rb)))
which produces a dict that maps ZIP codes to time zones.

Thanks Peter, that basically works, even if I don't understand it.
What does rb mean? (read binary?)
Why are the keys turned into strings (they are not quoted in the .csv file)?

rb is read, in binary mode. On DOS and derivatives this prevents intentional
file corruption when reading. (for ASCII files, omitting the b might be
desirable...)
Think of csv.reader as a fancy variant of the following: (fancy in that it
supports things like non-comma separators and comma escaping)
def CSVReader(file):
for line in file:
yield line.split(',')

Re: SMTP server w/o using Twisted framework
If you just want to send mail, you should be able to use the standard smtplib module (http://docs.python.org/lib/module-smtplib.html). If your recipients are on the Internet, you would need to handle MX resolution yourself. I know you said you want to avoid a relay server, but it's probably the best bet unless you control the SMTP infrastructure or are simply sending messages locally. Otherwise, you'll probably need to also implement queuing and retry logic (depending on your requirements). There are also some warning lights that may go off and flag your mail as spam if you're using a method like that... -Jeff On 7/5/07, _spitFIRE [EMAIL PROTECTED] wrote: Is it possible to run a SMTP server that sends mail to recipients using standard libraries, without using twisted framework, and also without using any relay server? -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list

You ought to be able to use the third arg of raise to raise a new
exception as if it were from the previous location, but now with
a new message.
You may need the traceback module to get at the error message, if
trying to read e.message can fail.
Something like this mess here: ;)
...
except Exception, e:
etype, evalue, etb = sys.exc_info()
ex = traceback.format_exception_only(etype, evalue)
message = ex[0].partition(':')[2].strip()
raise etype, message+. Sorry!, etb
Note that the above will break for SyntaxError (who's message
contains more than one line) and any kind of exception that
doesn't inherit from Exception.
You might need some crufty try, finally to avoid having a
circular reference hang around, according to the docs for
sys.exc_info.

The obvious naming is s1.intersects(s2) which reads as s1 intersects s2, a perfectly cromulent sentence. Agree.
