Are you sending all the lines in a single packet:
>>> sock.send('\n'.join(lines))
or sending them one at a time:
>>> for line in lines:
>>> sock.send(line + '\n')
? If the latter, you are probably experiencing "Nagle delays". Google
will furnish you with any number of explanations of what that means, but
in summary, one end of a TCP/IP connection should never send two
consecutive small packets without receiving a packet from the other end.
('Small' typically means less than about 1400 bytes.) Each time you do
that, you'll suffer an artificial delay introduced by TCP/IP itself.

It *didn't* work, as it turns out. It didn't overwrite python24.dll.

I'd be surprised if the existing 2.4 was per-user, because I usually ask for all-users. It's possibly that it was an all-users installation but I copied the DLL into C:\Python24 for some reason [...digs around...] yes, I think that must be the case. It has a creation date much later than C:\python24\Lib, for example. The python24.dll in C:\windows\system32 is 2.4.1c1.

I think it's your JavaScript '\r' processing that's broken. Certainly the
error ("unexpected EOF while parsing") is consistent with having a \r on the
end of the expression. Won't this:
if (input.length == 1)
always fail in the case where the user has typed a newline? I'd ditch that
code and do it at the server end:
expr = expr[4:].strip()

That's a carriage return, not a newline:

Ah, OK. Your comment talks about DOS - that won't happen on DOS (or
Windows) which uses \r\n. I don't know about the Mac. But the \r\n pair
isn't handled by your code - strip() on the server side will make it work if
that's the problem:

[Pierre] > I am Karrigell's author.

Which one would you advice : BSD ? Python licence ? another ? Well done on being open-minded! You will hear valid arguments for GPL, LGPL, BSD and other licenses (though the Python license is unsuitable for anything other than Python - see http://wiki.python.org/moin/PythonSoftwareFoundationLicenseFaq) A good solution would be multiple-licensing. You state that the code is (for example) triple-licensed under the GPL, LGPL and BSD licenses. The user of your code decides which license to obey. It's no more work for you, and you can please almost everyone (the only people you won't please are those who believe that there is One True License, and frankly you should ignore them - it's your code). The only downside of allowing people to choose the BSD license rather than the GPL is that potentially someone can choose the BSD license, improve Karrigell, ship their product based on the improved code, and not give those improvements back to the community. But the Python license allows for this too, and Python hasn't suffered for it. IMO choosing a BSD license will get you more users than GPL, and the benefits of that will outweigh the potential downside. -- Richie Hindle [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list

Re: Which Python web framework is most like Ruby on Rails?
[Paul] > The web app gets run by Karrigell like a CGI script > is run by Apache, like a Linux app is run by the Linux kernel. Paul, you keep making comparisons between Python web frameworks and the Linux kernel. Are you aware that there is a special note attached to the Linux GPL[1] explaining that user-space code is not considered a derived work of the Linux kernel? Without that note, user-space code *could* be considered a derived work of the kernel (obviously, or Linus Torvalds would not have included the note). Unless a GPL web framework carries a similar notice, the comparison doesn't hold up.

You need urllib.unquote:
>>> import urllib
>>> help(urllib.unquote)
Help on function unquote in module urllib:
unquote(s)
unquote('abc%20def') -> 'abc def'.
