Portland area Code Sprint on April 9-10
XP / PYTHON CODE SPRINT XPDX will be hosting a code sprint on April 9-10, 2005 in downtown Portland, Oregon. We're all meeting in one big room, where we'll code and talk smack until beer-thirty. Come pair with long-time XPers to learn their techniques while working on nifty Python projects. If you're intending to attend at least part of the sprint, please email Arlo Belshee ([EMAIL PROTECTED]). You can also add your name to the Sprint wiki, at http://c2.com/cgi/wiki?XpCodeSprint . We've currently got about 20 confirmed attendees from Oregon, Washington, and California. There's no headcount limit; come on down and join us for a weekend of coding, learning, and fun. If you can't make it for the whole weekend, just tell Arlo which day you can make it for. Many of the attendees are new to Python. Some are experts. So feel welcome regardless of your skill level. Also, Python integrates well with other common languages, allowing us to easily blend in work in a number of different areas. There will probably be projects in a number of different languages, such as: * Pure Python * Python and C++, via boost.org's boost::python interoperability template library * Python and Java, via Jython * And probably some Smalltalk, just because This is not a pure XP Sprint. Please feel free to come if you've never even heard of the practice. Many of us will be learning it this weekend. Also, if you have no interest in XP, come anyway. There will be a lot of Python coding and a variety of interesting topics. There are several potential projects for you to work on. If any of these catch your eye, come to the sprint ready to plow into it. If they don't, come on down with your own pet project - or even with no project at all. Someone'll grab you as a pair partner. http://pythoncard.sourceforge.net/ http://moinmoin.wikiwikiweb.de/, or MoinMoin plugins. http://scons.sourceforge.net/ http://ipodder.sourceforge.net/index.php Agile programming infrastructure. Some (as yet poorly defined) set of integrated tools to allow unit testing, automated build, automated smoke testing, release control, SCM, and other necessary activities. How about a rocket telemetry data analysis or visualization tool for http://psas.pdx.edu/? We could even provide live hardware. Scope, a simpler automated test framework for C++ that takes advantage of the features of that language. --- LOCATION AND LOGISTICS Critical Path Software his kindly invited us to use a floor of its downtown facilities for this sprint. The office is at 711 SW Alder St. in downtown Portland. It is about a block from Pioneer Courthouse Square, so is an easy MAX ride from many places in the city. The code sprint will run on April 9th and 10th. We will start each day at 10:00, and run until evening. Saturday night, several of us will probably troop on down to one of the local beer establishments. Arlo Belshee is organizing this event.

[ANN] Release 0.27 of Task Coach
Hi all, I am pleased to announce release 0.27 of Task Coach. This release adds one feature: - Tasks can have a budget. You can set a time budget for tasks. If you also track effort for that task you can tack how much of the budget is still left. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://taskcoach.niessink.com https://sourceforge.net/projects/taskcoach/ A binary installer is available for Windows XP, in addition to the source distribution. Thanks, Frank -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html

EOL created by .write or .encode
Why is that some of my files written out by

both of these files's EOL are originally all ascii 10.
If i remove the EOL after the tt below in the place string, then this
doesn't happen.

Re: re module non-greedy matches broken
* lothar [EMAIL PROTECTED] wrote: no - in the non-greedy regex 1st-patnot-1st-pat*?follow-pat 1st-pat, not-1st-pat and follow-pat are arbitrarily complex patterns. The not is the problem. Regex patterns are expressed positive by definition (meaning, you can say, what you expect, but not what you don't expect). In other words, regexps were invented to define (uh... regular) sets, nothing more (especially you can't define non-sets). So the usual way is to define the set you've called 'not-1st-pat*?' and describe it as regex. Modern regular expression engines (which are no longer regular by the way ;-) allow shortcuts like negative lookahead assertions and the like. I want to make clear, that it isn't, that nobody _wants_ to give an advice how to express your pattern in general. The point is, that there's no real syntax for it. It depends on how your 1st-pat and follow-pat look like. Chances are, that's even not expressable in one regex (depends on the complexity and kind of the set they define). Each pattern you write is special to the particular use case. Said that, there are some common patterns on how to write some specific forms of regexes. I also suggest Friedl's book. Look for the C-comment-example, where your problem (more or less) is discussed execessively. Though I really recommend to read the book from start to end. It's more like a story, but a good one ;-) with character classes and negative character classes you do not need non-greediness anyway. AFAICS one needs non-greedy regexps very very rarely at all. I'm playing with regular expressions for about ten years now and I've actually used them, say, two or three times -- and only for quick hacks. I've never actually _needed_ them. nd -- http://mail.python.org/mailman/listinfo/python-list

Python Google Server
I've hacked together a 'GoogleCacheServer'. It is based on
SimpleHTTPServer. Run the following script (hopefully google groups
won't mangle the indentation) and set your browser proxy settings to
'localhost:8000'. It will let you browse the internet using google's
cache. Obviously you'll miss images, javascript, css files, etc.
See the world as google sees it !
(This is actually an 'inventive' short term measure to get round a
restrictive internet policy at work :-) I'll probably put it in the
Python Cookbook as it's quite fun (so if line lengths or indentation is
mangled here, try there). Tested on Windows XP, with Python 2.3 and IE.

Re: monitoring folder in python
A straw-man solution in Python that monitors a directory for changes (Linux only): #!/usr/bin/env python2 import sys import os if sys.platform not in (linux2,): sys.exit(%s only runs on Linux % os.path.basename(sys.argv[0])) # TODO: we should check that kernel version = 2.4.19 # e.g. with 'uname -r' import fcntl import signal TESTDIRECTORY = . def notify(directory, handler): fd = os.open(directory, os.O_RDONLY) fcntl.fcntl(fd, fcntl.F_NOTIFY, fcntl.DN_ACCESS|fcntl.DN_MODIFY|fcntl.DN_CREATE) signal.signal(signal.SIGIO, handler) def handler(signum, frame): print Something happened; signal =, signum if __name__ == __main__: notify(TESTDIRECTORY, handler) try: signal.pause() # sleep until signal received except KeyboardInterrupt: pass With Python 2.4 one could bind e.g. to signal.SIGRTMIN instead of the default SIGIO and get additional info, as suggested by the C example in Documentation/dnotify.txt (look in the Linux src tree). But then I am note sure you can access a siginfo structure directly from Python. With the example above, one would probably write the handler so that it rescans the directory when called to detect what actually changed.

Re: Decorator Base Class: Needs improvement.

Steve Holden wrote:
You have several times mentioned the possibility of a decorator
taking
more than one argument, but in my understanding of decorators this
just
wouldn't make sense. A decorator should (shouldn't it) take precisely
one argument (a function or a method) and return precisely one value
(a
decorated function or method).
I agree from an English language point of view. I.e., a verber is
something that does the verbing, so a decorator ought to be the thing
that does the decorating, which is the function/callable(s) resulting
on stack from the evaluation of the @-line.
In the case of a single @deco name, the evaluation is trivial, and
the difference between the @-expression and the resulting callable
might be overlooked. Full-fledged general expressions after the '@'
are for some reason disallowed, but it is handy to allow attribute
access and calling in the syntax, so the relevant Grammar rules are:
From the 2.4 Grammar, the key part seems to be
decorator: '@' dotted_name [ '(' [arglist] ')' ] NEWLINE
decorators: decorator+
funcdef: [decorators] 'def' NAME parameters ':' suite
and further on
dotted_name: NAME ('.' NAME)*
So the Python Grammar's name for the @-expression is just plain decorator
which conflicts with my English-based reading of the word ;-/
So it appears the intent is to call the entire @-line the decorator
and I guess to have a name for what evaluating the @-line returns on the
stack, we could call it the decorating callable since it is what takes
the function parameter as its first parameter and decorates the function
and returns the decorated function.
But I don't like it, English-wise. I would rather call the @-line
the decorator expression and what it evaluates to the decorator.
Can we change the grammar with s/decorator/decorator_expr/ ?
Yes. I think this sould be fixed into the minds of the people exacly
this way You state it:
I think we may be agreeing in principle but with different words ;-)
When writing
@decorator(x,y)
def f():
not the so called decorator function but decorator(x,y) is the
^--(the result of evaluating)
decorating function and decorator(x,y) is nothing but a callable object
^--(the result of evaluating)
that takes f as parameter. A little correcture of Your statement: it is
NOT nessacary that a function or method will be returned from a
decorator.
Yes, in fact it could even perversely be colluding with a known succeeding
decorator callable to pass info strangely, doing strange things, e.g.,
trick = ['spam', 'eggs']
def choose_name(tup):
... nx, f = tup
... f.func_name = trick[nx]
... return f
...
def namedeco(nx=1):
... return lambda f, nx=nx:(nx, f)
...
@choose_name
... @namedeco()
... def foo(): pass
...
foo
function eggs at 0x02EE8E64
@choose_name
... @namedeco(0)
... def foo(): pass
...
foo
function spam at 0x02EE8DF4
I.e., namedeco evaluates to the lambda as decorator function,
and that passes a perverse (nx, f) tuple on to choose_name, instead
of a normal f.
def decorator(x,y):
def inner(func):
return x+y
return inner
@decorator(1,2)
def f():pass
f
3
This is perfectly valid allthough not very usefull ;)
Perhaps even less useful, the final decorator can return something
arbitrary, as only the name in the def matters at that point in
the execution (as a binding target name), so:
def dumbdeco(f): return 'something dumb'
...
@dumbdeco
... def foo(): pass
...
foo
'something dumb'
Hm, maybe some use ...
def keydeco(name):
... return lambda f: (name, f)
...
@keydeco('pooh_foo')
... def foo(): pass
...
@keydeco('tigger_bar')
... def bar(): pass
...
dict([foo, bar])
{'pooh_foo': function foo at 0x02EE8DBC, 'tigger_bar': function bar at
0x02EE8DF4}
... nah ;-)
Anyway, I think a different name for what comes after the @ and the
callable that that (very limited) expression is supposed to return
would clarify things. My conceptual model is
@decorator_expression # = decorator
def decorating_target(...):
...

Thanks for the report. I've also tried it with firefox on windows.
Yeah - google search results aren't cached !! Perhaps anything in a
google domain ought to pass straight through. That could be done by
testing the domain and using urllib2 to fetch the page.
Have just tested the following which works.
Add the follwoing two lines to the start of the code :
import urllib2
txheaders = { 'User-agent' : 'Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.1; SV1; .NET CLR 1.1.4322)' }
Then change the start of the send_head method to this :
def send_head(self):
Only GET implemented for this.
This sends the response code and MIME headers.
Return value is a file object, or None.
print 'Request :', self.path # traceback to sys.stdout
url_tuple = urlparse.urlparse(self.path)
url = url_tuple[2]
domain = url_tuple[1]
if domain.find('.google.') != -1: # bypass the cache for

However when I use SQLyog to look at the database the info isn't there. When I close down Python, restart, reconnect and query the info isn't there. Info inserted from SQLyog is persistant.

The difficulty is 'on some other machine'... there's a fantastic python CGI proxy called approx - http://www.voidspace.org.uk/python/cgi.shtml#approx The trouble is the current policy is 'whitelist only'... so I need the proxy installed on a server that is *on the whitelist*... which will take a little time to arrange.

os.path query functions behavior incorrect?
The docs for os.path.exists(), isdir(), and the like, do not describe behavior when an I/O error occurs. Testing on Windows XP SP2 with Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)] on win32, on a machine with no a: drive, c: is a hard disk with a top level directory named path but without a top level directory named foo, and d: is a CD drive (with no disc inserted): import os print os.path.exists(c:\\) True print os.path.isdir(c:\\) True print os.path.isdir(c:\\boost) True print os.path.isdir(c:\\foo) False OK, that meets my expectations. But now: print os.path.exists(a:\\) False print os.path.isdir(a:\\) False print os.path.exists(d:\\) True print os.path.isdir(d:\\) True These to me are I/O errors that should result in an exception. Doing a command line dir a:\ reports The system cannot find the path specified. Dir d:\ reports The device is not ready. So are these os.path functions specified and implemented incorrectly? Should they instead throw exceptions for the above examples? If they are specified and implemented correctly, what is the rationale for this behavior?

Re: re module non-greedy matches broken
a non-greedy match - as implicitly defined in the documentation - is a match in which there is no proper substring in the return which could also match the regex. you are skirting the issue as to why a matcher should not be able to return a non-greedy match. there is no theoretical reason why it can not be done. André Malo [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] * lothar [EMAIL PROTECTED] wrote: no - in the non-greedy regex 1st-patnot-1st-pat*?follow-pat 1st-pat, not-1st-pat and follow-pat are arbitrarily complex patterns. The not is the problem. Regex patterns are expressed positive by definition (meaning, you can say, what you expect, but not what you don't expect). In other words, regexps were invented to define (uh... regular) sets, nothing more (especially you can't define non-sets). So the usual way is to define the set you've called 'not-1st-pat*?' and describe it as regex. Modern regular expression engines (which are no longer regular by the way ;-) allow shortcuts like negative lookahead assertions and the like. I want to make clear, that it isn't, that nobody _wants_ to give an advice how to express your pattern in general. The point is, that there's no real syntax for it. It depends on how your 1st-pat and follow-pat look like. Chances are, that's even not expressable in one regex (depends on the complexity and kind of the set they define). Each pattern you write is special to the particular use case. -- http://mail.python.org/mailman/listinfo/python-list

Re: re module non-greedy matches broken
a non-greedy match is implicitly defined in the documentation to be one such that there is no proper substring in the return which could also match the regex. the documentation implies the module will return a non-greedy match. the module does not return a non-greedy match.
