ANN: Cheesecake Service launched and Cheesecake 0.6.1 released
Thanks to the hard work of Michal Kwiatkowski, I'm proud to announce the launch of the Cheesecake Service (http://pypi.pycheesecake.org/ pypi/) and the release of Cheesecake 0.6.1 (http://python.org/pypi/ Cheesecake/0.6.1).

FlightFeather Social Networking Platform 0.3.3
FlightFeather's goal is social networking for everyone. This means that *anyone* should have a chance to run a *popular* social networking site -- on minimal hardware, and without wasting bandwidth. Version 0.3.3 is the current development release. It modifies the way the FlightFeather server loads the configuration, protocol, session, and storage modules on startup. The actual loading process now takes place after all options have been parsed. If the -c or --command option is present, the server does not import these modules at all, since they are not required. The new implementation also fixes a bug that caused the test versions of the above modules to always load, in addition to any modules specified on the command line. The current beta release of FlightFeather is 0.2.8. You can download these releases (free/open source under the GPL) from the BoSStats site, which runs on FlightFeather. http://www.bosstats.com/flightfeather.html You are always welcome to participate in the discussion on the BoSStats site; the topic covered (what makes a good boss, office politics, etc.) is valuable in and of itself. Please, however, refrain from posting test comments, as the site is live. A Brief Overview of FlightFeather and BoSStats -- You can see FlightFeather in action on the BoSStats site. BoSStats is dedicated to improving the world of work: you can discuss what makes a good boss, or share your experiences of office politics. You can also comment and vote on the posts made by others. The application does not set cookies, and no registration is required for anything except voting. http://www.bosstats.com/ BoSStats is a good testbed for FlightFeather, and has value of its own, since meaningful advice about work-related problems is very hard to find. A Wisdom of Crowds solution -- particularly with strong privacy protection (see below) -- is a necessary addition to this field. FlightFeather's most important feature is that all write requests generate (or modify) HTML files. In consequence, a pure read (the most common operation) merely serves static pages. The major design focus for FlightFeather are responsiveness and performance; the system should eventually support very high traffic volumes. In addition, FlightFeather allows for a great deal of user privacy -- a critical, rapidly emerging problem in the social networking realm. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html

(Why routine() and not main()? Unfortunately you can't repeteadly
initialize/finalize the interpreter, you must do that only once.)
The code compiles just fine, but when I execute it the call to
Py_Initialize() comes back with:
'import site' failed; use -v for traceback
Traceback (most recent call last):

ImportError: No module named time
Try this:
PyRun_SimpleString(import sys; print sys.path);
to see where Python expects to find its library (or call the Py_GetPath
function).
You may need to call Py_SetProgramName (before Py_Initialize) so it can
find where the standard library resides.
At least for testing purposes, you can copy your executable into the same
directory where Python is installed.

So the server has sent you a cookie back, and cookielib accepted it.
Success!
What your PHP program prints out is information about cookies that
were received *from* the browser (or from your script, in this case).
It does not print information about cookies that it is sending *to*
the browser. Your PHP program is not a time machine, so it can't
print out information about a cookie that was *not there* in the
request you sent. And the cookie was not there in the request you
sent because the server hadn't sent the cookie yet!
Send a second request (either in the same run of your program, or by
saving and loading the cookies), and you should see a cookie sent back
to the server (and then printed out by your PHP script in the response
you get back). Web sites and web applcations sometimes use a trick
like a using a redirect or Refresh to get the browser to send a
second request, so that they get the cookie they set sent back to the
server again, without the user needing to perform any second action.
Also note that saving and loading cookies with cookielib will by
default drop session cookies, unless you explicitly ask otherwise.

[...] Presumably Windows? (Unix systems almost always have at least a loopback interface) John Sorry, I should have been more specific. The network interfaces are up - ie lo and eth1, it's where the wireless connection has dropped out. The underlying problem is that Python's socket timeout is implemented using select() or poll(). Those system calls only allow timing out activity on file descriptors (e.g. sockets). The problem you're seeing is caused by getaddrinfo() blocking for a long time, and that function doesn't involve file descriptors. The problem should really be fixed at the C level (in Modules/socketmodule.c), using something like alarm() or a thread to apply a timeout to getaddrinfo() calls. Seems doing this portably with threads is a bit of a nightmare, actually. You'd have to extend every one of CPython's thread implementations (pthreads, Solaris threads, etc. etc. etc.) -- and I don't even know if it's possible on all systems. And since the GIL is released around the getaddrinfo() call in socketmodule.c (and that can't be changed), one can't guarantee that a Python thread won't set a different signal handler, so alarm() is not good. And of course Windows is a separate case. Is the best solution to test for a wireless connection through / proc before trying to download data? That may be a good practical solution. Another workaround that might be useful is to do your DNS lookups only once, then use only IP addresses. The portable way to actually solve what I assume is your underlying problem (latency in a GUI) is to have a Python thread or separate process do your urlopen()s (this can be done at the Python level).

Re: pygame and python 2.5
Python used to work that way. You'd then silently get errors if the API changed between version A and version B and you neglected to recompile the extensions you compiled against version A. bearophile Can't the compiled module have one or more test functions bearophile that can be used during linking to see if the compiled bearophile module respects the expected standard? Given the complexity of the formal API how would you test to see if the extension violated a particular aspect of the API? What if one of the API bits used is implemented as a C macro (as parts are) and it was changed simply to fix a bug. Wouldn't you want to know with a high degree of certainty that you should recompile? How would a test function tell you that? A simple API versioning scheme does that. It means you have to recompile when a new version of Python comes out. In fact, you can think of it as the test function you suggest. It's just that it's noted at the time a module is imported, not strictly speaking at link time. It tells you, Hey buddy. You're using an outdated version of the API. What it can't tell you is if the parts of the API your particular module uses are used incorrectly. Skip -- http://mail.python.org/mailman/listinfo/python-list

Must I use regex?
There are two approaches: one is the solve once and forget approach
where you code around this particular problem. Mario showed you one
solution for this.
The other approach would be to realise that your problem is a specific
case of two general problems: partitioning a sequence by a separator
and partioning a sequence into equivalence classes. The bonus for this
approach is that you will have a /lot/ of problems that can be solved
with either one of these utils or a combination of them.
1 a = '45 324 45324'
2 quotient_set(part(a, [' ', ' '], 'sep'), ident)
2: {'324': ['324'], '45': ['45'], '45324': ['45324']}
The latter approach is much more flexible. Just imagine your problem
changes to a string that's separated by newlines (instead of spaces)
and you want to find words that start with the same character (instead
of being the same as criterion).

wxPython libraries never detected
Hi, I recently started coding with Python and I've been trying for the past hour or so to determine why, every time I import wx (or compile another piece of code that imports wx), Python can never find the libraries. I'm running Ubuntu Edgy 6.10, and, as per http://www.wxpython.org/download.php#sources, updated sources.list with the sources and installed python-wxgtk2.8, python-wxtools and wx2.8-i18n. I compiled the latest Python (as of writing), 2.5, from source. For example, SPE tells me that I need to install at least wxPython v. 2.5.4.1 to run SPE and any code that relies on import wx reports ImportError: No module named wx. However, whereis wx on the command line reports wx: /usr/lib/wx /usr/local/lib/wx /usr/include/ wx. What could be wrong here? I can't figure out why wx isn't being detected.

Data point: When using winsock2, the number of simultaneous TCP connections is limited by the FD_SETSIZE preprocessor constant, which is often 64. It must be set before including winsock2.h.

Re: Something like the getattr() trick.
This is a really common question. What you really need here is to
lookup some value (one of the two classes) by a key (the names of the
classes). Does that sound like something familiar? You seem to need a
dictionary, where you think you want lookup some global objects by
name.
Alternatively, if you use new-style classes (by`inheriting the object
class in your base class), you could perhaps add a method such as
getSubClass() like:
class Vuln(object):
...
@classmethod
def getSubClass(cls, name):
for c in cls.__subclasses__():
if c.__name__ == name:
return c
raise ValueError(No subclass named '%s' found. % name)
Of course, this only makes sense if you needs dont extend outside the
pattern of looking up subclasses by name. It has the advantage that
you can also put the subclasses in other modules and still look them
up from one place.

Of course, functions get called at the ends of the message passing process, but those functions can stay the same across versions while the messages themselves change. The important part is reducing the binary interface between the two sides to a level where it's trivial to guarantee that part of the equation is safe. eg.

That function can return NULL and set up an exception if it doesn't understand the object you asked for, so Python versions earlier than the one that implement the type you want will just raise an exception gracefully rather than not linking.

I have tried parsing the html with pyparsing, and the examples will get it to print all instances with span, of which there are a hundred or so when I use: for srvrtokens in printCount.searchString(printerListHTML): print srvrtokens If I set the last line to srvtokens[3] I get the values, but I don't know grab a single line and then set that as a variable. I have also tried Beautiful Soup, but had trouble understanding the documentation, and HTMLParser doesn't seem to do what I want. Can someone point me to a tutorial or give me some pointers on how to parse html where there are multiple lines with the same tags and then be able to go to a certain line and grab a value and set a variable's value to that?

Re: Best Free and Open Source Python IDE

Re: Need a cross-platform way to execute binary
En Sat, 10 Feb 2007 08:48:31 -0300, techtonik [EMAIL PROTECTED] escribió: On Feb 10, 12:03 pm, Gabriel Genellina [EMAIL PROTECTED] Here executable means file that could be be launched by system() (if there are any other ways - I'd be happy to know them) This is a very specific definition of executable. os.access does not use that definition. os.access(../../ufo2map, os.X_OK) False That's right - such file does not exist. On Windows, in general, X_OK is the same as F_OK: for any existing file, whatever name or extension, returns True. Permissions are managed thru ACL and this simple function does NOT consider them. It shouldn't matter if the file exists or not. Quoting http:// docs.python.org/lib/os-file-dir.html: X_OK Value to include in the mode parameter of access() to determine if path can be executed. See - there is no file notation as only path is tested and path is pretty executable. It appears that your argument is: os.system(../../ufo2map) launches a new process, so ../../ufo2map must be executable. But os.system(foo.txt) also works, so foo.txt is also executable? Please define executable first. The definition may be so restrictive as to only include PE files (all others require a wrapping process) or so broad as to include almost anything known to the system. I think this should be clarified in os.access() documentation to make the whole business less confusing if not implemented in interpreter itself. After all the purpose of cross- platform language is to free developer from writing platform-specific code. os.access documentation is rather clear - it's just a wrapper around the access() system call, and I think it should not be changed. It is the underlying OS which gives the answer, not Python. On the other hand, an utility library exposing FindExecutable, ShellExecute, associations and other shell goodies might be useful. Maybe you could do some research, whether such thing exists, and help improve it or design a good interfase? I would prefer to know as little about underlying platforms as possible. It would only be a big plus for Python. Sure, but someone has to write it. I can't think of a good abstraction right now, perhaps you have some ideas? -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
