XPN (X Python Newsreader) is a multi-platform newsreader with Unicode support. It is written with Python+GTK. It has features like scoring/actions, X-Face and Face decoding, muting of quoted text, newsrc import/export, find article and search in the body, spoiler char/rot13, random taglines and configurable attribution lines. You can find it on: http://xpn.altervista.org/index-en.html or http://sf.net/projects/xpn Changes in this release: * added message-id recognition. Now XPN tries to recognize message-ids in the text and make them clickable in order to open a search window. * added a dialog window that informs you when XPN downloads new articles in watched threads. * some improvements in Global Search, now is possible to perform multiple searches. * now XPN checks if there are other istances running (it uses the file xpn.lock in the XPN directory). This behaviour should prevent database break off. * some fixes in the Score Window * fixed some bugs in header management * fixed a bug that caused crashes with multipart articles with email attached XPN is translated in Italian French and German, if you'd like to translate it in your language and you are familiar with gettext and po-files editing please contact me ([EMAIL PROTECTED]). -- No wanna work.

robert [EMAIL PROTECTED] wrote:

What? When I add/del an item to a dict or list, this is not an atomic

Exactly: there is no such guarantee in the Python language.
E.g.:
One thread does things like d['x']='y'
Another thread reads d['z'] or sets d['z']='w' or dels something.
If those operations are not atomic, then you'd have to use locks all the
time to not get RuntimeErrors and worse !?
If you want to be writing correct Python, yes. A preferred approach is
to simply avoid sharing objects among threads, except for objects
designed to be thread-safe (chiefly Queue.Queue).
I don't know the Python language (non?-)definition about this. But the
day, that will be a requirement in the Python implementation, I'll put
the last Python in a safe :-) ( ..and rethink my bad opinion about Ruby )
For example hundreds of things like sre._cache and tenthousands of
common global variables are shared thread safe in the standard lib
whithout locks.
;-) They never will change any Python implementation and do the work to
put millions of lock.acquire()'s into the standard lib...
Infact I rely on that all the time and standard python modules also do
so AFAIK
You're relying on an accident of a specific, particular implementation;
if any Python-coded standard library module does likewise, and I'm not
aware of any, that's somewhat different (since that module is PART of
the implementation, it may rely on all kinds of implementation details,
correctly if maybe not wisely). The situation is quite different for
C-coded modules in the CPython implementation, Java-coded ones in the
Jython one, C#-coded one in the IronPython one; each of these is subject
to specific constraints that it's perfectly wise to rely on (since each
implementation, as the language specification fully allows it to do,
adopts a different locking strategy at these low levels).
the other implementations whould also have a hard time to rewrite the
standard lib.
Python byte code is kind of defined and always interpreted similar and..
d={'a':1}
def f():
... print d['a']
... print d.keys()
... d['b']=2
...
dis.disassemble(f.func_code)
2 0 LOAD_GLOBAL 0 (d)
3 LOAD_CONST 1 ('a')
6 BINARY_SUBSCR
7 PRINT_ITEM
8 PRINT_NEWLINE
3 9 LOAD_GLOBAL 0 (d)
12 LOAD_ATTR1 (keys)
15 CALL_FUNCTION0
18 PRINT_ITEM
19 PRINT_NEWLINE
4 20 LOAD_CONST 2 (2)
23 LOAD_GLOBAL 0 (d)
26 LOAD_CONST 3 ('b')
29 STORE_SUBSCR
30 LOAD_CONST 0 (None)
33 RETURN_VALUE
..things like LOAD_CONST / STORE_SUBSCR will be atomic as long as there
is a GIL or at least a GIL during execution of one byte code. No
threaded script language can reasonably afford to have thread-switching
open down to native microprocessor execution atoms.
I think cPickle has not necessarily to iterate free over native dicts.
It's not forced to by language specification, but neither is it
forbidden. It would be an absurd implementation strategy to waste time
and space to extract a dict's keys() first, as it would NOT buy
atomicity anyway -- what if some other thread deletes keys while
you're looping, or calls any nonatomic method on the very value you're
in the process of serializing?!
First I look at the practical requirement: I have the threads and the
fast object tree and the need to autosave in this process. And don't
want to lock everywhere any dict-access to the tree just because of the
autosave (for app-reasons I need only a handful of locks so far). And I
don't want to use a slow overkill method like ZODB.
One clean method (A) in order to stay practical would be possible if a
global lock for Python treading would be offered by the thread-lib as
described in [EMAIL PROTECTED]
The other method (B), (that I believed to use so far) is to have a
little discipline, but no need for massive trivial locking:
* add complex objects to the hot tree only if the objects are
complete/consistent.
* don't do nasty things on removed complex objects; just forget them as
usual
* most attribute changes are already app-atomic; the overall majority of
operations is read-only access anyway - both regarding the number of
executions and the amount of source code (that is 99% the reason for
using this disciplined method in threaded apps)
* ..in case of non-atomic attribute changes, create a new appropriate
top object with compound changes (same logic as in fact you have, when
you use ZODB) and replace the whole top object in one step. Or use locks
in rare cases.
Now a practical autosave method in my app could fit to such practical
disciplined method ( or not :-(

My mistake comes from the subtle difference between defining descriptor as a class and by property() builtin (I've tested only second option and assumed that descriptor without __set__ cannot be rebinded): property is always overriding, of course, since type property does have a property.__set__ (which raises an exception if you build the instance of property w/o a setter function). class non_overriding(object): def __get__(*a): return 12 class C(object): x = non_overriding() y = property(lambda s:23) c = C() c.x = 4 print c.x # = 4 c.y = 5 # = AttributeError: can't set attribute Right: another example of overriding and nonoverriding descriptors. IMHO that's not very consistent. How so? Given the lower-level semantics of descriptors (and the distinction between overriding and non), are you suggesting that property should not be a type but a factory function able to return instances of either overriding or non-overriding types? I'm not sure how that complication would make things consistent in your view. Well, probably some code rely on this, so I just have to live with it. Backwards-incompatible changes can be proposed for Python 3.0, if they lead to a situation that's preferable to what we have now.

True. As you say, there are links to bug reporting tools and, at least on the current site, lots of links to other, potentially useful resources - too many in the sidebar for my liking, though. However, other projects and companies tend to move things which developers using the technology might find useful to other, more focused pages. Again, looking at the PostgreSQL site, they have such resources available via the Support link: http://www.postgresql.org/support/ Meanwhile, keeping the more corporate style of site in mind, the Trolltech one does have bug tracking resources on the developer page, but then that page isn't really about developing the offered products themselves, so there is really only one kind of developer audience involved.

Yes, that was my first thought, but I think since the PFS is directly involved in recruiting and organizing support for the development of python and the python community, it probably needs to be a bit more prominent than that. I think there is still room for improving the grouping of the web site in general. For example you could consider that there are three major groups... * For Python users: Those using python to write programs. This would b e the introduction, the user/library guide, the tutorial, and other documentation on how to use python for writing programs along with the download links for the current versions. * Python product(s) suppliers: Finished applications modules and tools written in python and third party information/products for python users. (outside website links, books, t-shirts, and other items ... also fit in this catagory) * Python development and support: For the development of the python core and the python library, the documentation, and the web site. As well as the PFS. These overlap, but the nice thing about hyper linked documents is that general groupings can be maintained and it still works. While the PFS is in the third group, since it is involved in both seeking and promoting support of python, it needs to be visible in the other groups as well. Of course, others would probably arrange things differently. :) Ron -- http://mail.python.org/mailman/listinfo/python-list

Customizing character set conversions with an error handler
When converting Unicode strings to legacy character encodings, it is
possible to register a custom error handler that will catch and process
all code points that do not have a direct equivalent in the target
encoding (as described in PEP 293).
The thing to note here is that the error handler itself is required to
return the substitutions as Unicode strings - not as the target encoding
bytestrings. Some lower-level gadgetry will silently convert these
strings to the target encoding.
That is, if the substitution _itself_ doesn't contain illegal code
points for the target encoding.
Which brings us to the point: if my error handler for some reason
returns illegal substitutions (from the viewpoint of the target
encoding), how can I catch _these_ errors and make things good again?
I thought it would work automatically, by calling the error handler as
many times as necessary, and letting it work out the situation, but it
apparently doesn't. Sample code follows:
--- 8 ---
#!/usr/bin/python
import codecs
# ==
# Here's our error handler
# ==
def charset_conversion(error):
# error.object = The original unicode string we're trying to
#process and which has characters for which
#there is no mapping in the built-in tables.
#
# error.start = The index position in which the error
#occurred in the string
#
# (See PEP 293 for more information)
# Here's our simple conversion table:
table = {
u\u2022: u\u00b7, # BULLET to MIDDLE DOT
u\u00b7: u*# MIDDLE DOT to ASTERISK
}
try:
# If we can find the character in our conversion table,
# let's make a substitution
substitution = table[error.object[error.start]]
except KeyError:
# Okay, the character wasn't in our substitution table.
# There's nothing we can do. Better print out its
# unicode codepoint as a hex string instead:
substitution = u[U+%04x] % ord(error.object[error.start])
# Return the substituted string and let the built-in codec
# continue from the next position:
return (substitution,error.start+1)
# ==
# Register the above-defined error handler with the name 'practical'
# ==
codecs.register_error('practical',charset_conversion)
# ==
# TEST
# ==
if __name__ == __main__:
print
# Here's our test string: Three BULLET symbols, a space,
# the word TEST, a space again, and three BULLET symbols
# again.
test = u\u2022\u2022\u2022 TEST \u2022\u2022\u2022
# Let's see how we can print out it with our new error
# handler - in various encodings.
# The following works - it just converts the internal
# Unicode representation of the above-defined string
# to UTF-8 without ever hitting the custom error handler:
print UTF-8: +test.encode('utf-8','practical')
# The next one works, too - it converts the Unicode
# BULLET symbols to Latin 1 MIDDLE DOTs:
print Latin 1: +test.encode('iso-8859-1','practical')
# This works as well - it converts the Unicode BULLET
# symbols to IBM Codepage 437 MIDDLE DOTs:
print CP 437: +test.encode('cp437','practical')
# The following doesn't work. It should convert the
# Unicode BULLET symbols to ASTERISKS by calling
# the error handler two times - first time substituting
# the BULLET with the MIDDLE DOT, then finding out
# that that doesn't work for ASCII either, and falling
# back to a yet simpler form (by calling the error
# handler again, which will this time substitute the
# MIDDLE DOT with the ASTERISK) - but apparently it
# doesn't work that way. We'll get a
# UnicodeEncodeError instead.
print ASCII: +test.encode('ascii','practical')
# So the question becomes: how can I make this work
# in a graceful manner?

the problem is not so much my sound card, but that I am making some
fundamentally wrong assumption on the way to do this ;) Also I am
definitely a newbie when it comes to audio coding, so any corrections
or tips are welcome.
Here is some test code that is failing for me
from twisted.internet.task import LoopingCall
from twisted.internet import reactor
import os, sys, wave, audioop
While playing the contents of test1.wav, talk into the mic
and have the audio recorded into /tmp/out.wav
def playnlisten_out():
audio = wavin.readframes(1024)
stereoaudio = audioop.tostereo(audio, 2, 1, 1)
dsp.write(stereoaudio)
def playnlisten_in():
audio = dsp.read(640)
wavout.write(audio)
def both():
playnlisten_out()
playnlisten_in()
dsp = ossaudiodev.open('/dev/dsp', 'rw')
wavin = wave.open(test1.wav, r)
wavout = wave.open(/tmp/out.wav, w)
both_loop = LoopingCall(both)
both_loop.start(0.02)
reactor.run()
Actual behavior
It fails with an error:
dsp.write(stereoaudio)
exceptions.IOError: [Errno 19] No such device
If I comment either playnlisten_out() or playnlisten_in() then the
other function will work. They just don't work at the same time.

Of course, just because __slots__ were invented for one purpose doesn't mean that you can't find another use for them, but this is not the way. PyChecker is a good solution for testing for misspelled variables. Another way is to avoid setters and getters: instead of creating a method to change the name and sex of the instance, just change the attributes directly. Not getters and setters means less code, and less code means fewer bugs (whether due to misspellings or not). The Original Poster, EP, wrote: def changeName(self, newname=): self.name=newname return self.name This is not a very Pythonic idiom. (I'm not saying that it is *wrong*, merely that it is unusual.) Generally, methods should implement one of two behaviours, as illustrated by the following simplified example: class Number(object): def __init__(self, num): self.value = num def __add__(self, other): add two instances of Number and return a new instance return Number(self.value + other.value) def increment(self, inc): increment this instance in place self.value += inc foo = Number(5) bar = Number(3) foo.increment(2) foo.value 7 baz = foo + bar baz.value 10 In other words, methods should generally return either a new instance, or nothing.

Re: Help Create Good Data Model
If you used a Queue, it wouldn't be the container itself; rather, it
would be a gatekeeper between the container and consumer code. A
minimal example of user-side code would be:
class Request:
def __init__(self, op, data):
self.op = op
self.data = data
self.reply = None
req = Request('get', key)
data_q.put(req, block=True)
while req.reply is None:
time.sleep(0.1)
do_something_with(req.reply)
The container-side code would be:
while True:
request = data_q.get(block=True)
request.reply = handle(request)
That can be improved with queue timeouts on both sides, but it shows
the basic idea.

Re: RuntimeError: dictionary changed size during iteration ; Good atomic copy operations?
[robert] In very rare cases a program crashes (hard to reproduce) : * several threads work on an object tree with dict's etc. in it. Items are added, deleted, iteration over .keys() ... ). The threads are good in such terms, that this core data structure is changed only by atomic operations, so that the data structure is always consistent regarding the application. Only the change-operations on the dicts and lists itself seem to cause problems on a Python level .. * one thread periodically pickle-dumps the tree to a file: cPickle.dump(obj, f) RuntimeError: dictionary changed size during iteration is raised by .dump ( or a similar ..list changed ... ) What can I do about this to get a stable pickle-dump without risiking execution error or even worse - errors in the pickled file ? Is a copy.deepcopy ( - cPickle.dump(copy.deepcopy(obj),f) ) an atomic opertion with a guarantee to not fail? No. It is non-atomic. It seems that your application design intrinsically incorporates a race condition -- even if deepcopying and pickling were atomic, there would be no guarantee whether the pickle dump occurs before or after another thread modifies the structure. While that design smells of a rat, it may be that your apps can accept a dump of any consistent state and that possibly concurrent transactions may be randomly included or excluded without affecting the result. Python's traditional recommendation is to put all access to a resource in one thread and to have other threads communicate their transaction requests via the Queue module. Getting results back was either done through other Queues or by passing data through a memory location unique to each thread. The latter approach has become trivially simple with the advent of Py2.4's thread-local variables. Thinking about future directions for Python threading, I wonder if there is a way to expose the GIL (or simply impose a temporary moratorium on thread switches) so that it becomes easy to introduce atomicity when needed: gil.acquire(BLOCK=True) try: #do some transaction that needs to be atomic finally: gil.release() Or can I only retry several times in case of RuntimeError? (which would apears to me as odd gambling; retry how often?) Since the app doesn't seem to care when the dump occurs, it might be natural to put it in a while-loop that continuously retries until it succeeds; however, you still run the risk that other threads may never leave the object alone long enough to dump completely.

Very, Very Green Python User
I have used Perl for a long time, but I am something of an experimental person and mean to try something new. Most of my 'work' with Vector Linux entails the use of Perl (a bit of a misnomer as it is not now a paid position -- I am not yet even out of K-12), and there a lot of things I love about it. I can look past a number of misfeatures in Perl, but I am surprised to see that Python has very few (that I know of). Most of them are documented here, it would seem: http://www.c2.com/cgi/wiki?PythonProblems. Is the Python debugger fairly stable? The one you get with Perl stinks on ice. More than anything else, I would like to have a powerful OO environment where I do not have to worry about the debugger sucking ass. A couple blemishes I'm concerned about, though: Python closures are apparently very poor, but from what I can surmise of the PyGTK2 page, instances of objects are dynamic enough to add new methods, so you get your callbacks, at least. Double-underscore methods are rewritten with the class name? That's an ugly hack, but remember I'm coming from Perl. If the language doesn't pull many other hijinks, that's OK.

Re: Tkinter / Mac OS X Question (Aqua vs. X11)
Install python using fink, and invoke that. Should work against X11 for all GUI-Toolkits. I prefer not to do this. Darwin is already a Unix, and Apple provides a version of X11 that works well with it. Fink seems like an unecessary layer that I would rather not mess with. Tcl/Tk has a very simple way to select. It would be nice if Python did something similar (command line option, an environment variable, whatever). I looked for an option in the build process, and from what I can tell, the OS X version looks like it only builds a single version (TkAqua). TkAqua and TkX11 do differ, and it would be nice to see the same script run under both Aqua and X11 without having to switch machines. -- http://mail.python.org/mailman/listinfo/python-list

As Steven mentioned, the GUI toolkits for python (and several other major programming languages such as Java and C) are challenging. I recommend you start with something that is already GUI-oriented that would eliminate a lot of the difficulty of display images, detecting mouse clicks, etc. The first thing that comes to mind would be Powerpoint with some short custom Visual Basic code. Another very easy alternative may be HTML with some basic Javascript. It won't take 10 lines of code if you make some compromises on the presentation but you can't include sound.

But if it's a string, why not just use a text file? What does a binary file do that a text file doesn't, aside from not converting the end of line characters? Nothing. It is all bytes under the hood. People generally consider a file to be text if it only includes bytes 32 through 126, plus a few control characters like 9 (tab) and 10 (newline). Other applications don't care what bytes are included. Python is (mostly) like that: you can deal with any bytes you collect from any file. Other than this informal difference between text an binary, the major difference comes about when you read lines from a text file. Each operating system has a line separator: Unix/BSD/Linux systems use newline (char 10), classic Macintosh used to use carriage return (char 12) and DOS/Windows uses a two-byte carriage return + newline. When writing lines to a file, Python does not automatically append the line marker, so you need to do so yourself. But some other languages do -- I believe C++ is one of those languages. So C++ needs to know whether you are writing in text mode so it can append that end-of-line maker, or binary mode so it doesn't. Since Python doesn't modify the line you write to the file, it doesn't care whether you are writing in text or binary mode, it is all the same. Operating systems such as Unix and Linux don't distinguish between binary and text mode, the results are the same. I'm told that Windows does distinguish between the two, although I couldn't tell you how they differ. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
