Tkinter Caps Lock Weirdness
by Steve Holden Aug. 31, 2000

Aug. 31, 2000

I just noticed that Idle (first 0.4, then 0.5 when I realised a recent re-install had lost it) stop the indicator for my caps lock key working on my IBM Thinkpad running Windows 98. Further tests indicate this is generally true of Tkinter-based programs. Is this a know feature? It doesn't actually stop anything working, but I mistrust such weirdnesses. regards Steve -- Helping people meet their information needs with training and technology. 703 967 0887 sholden(a)bellatlantic.net http://www.holdenweb.com/

Error message in Tkinter
by Janos Blazi Aug. 31, 2000

Aug. 31, 2000

Is there a simple way of displaying an error message dialog box in Tkinter? Such a dialog box should contain a message, possibly the exclamation mark and the ok button.

SocketServer and makefile()
by Andy Bond Aug. 31, 2000

Aug. 31, 2000

I've been working with BaseHTTPServer which in turn uses SocketServer to write a little web server. It is used to accept PUT requests of 30MB chunks of data. I was having a problem where data was flowing at the rate of something like 64K per second over a 100MB network. Weird. Further tracing showed that the rfile variable from SocketServer (used to suck in data to the http server) was created using makefile on the original socket descriptor. It was created with an option of zero for buffering (see SocketServer.py) which means unbuffered. Now some separate testing with socket.py showed that I could whip a 30MB file across using plain sockets and send/recv but if I made the receivor use makefile on the socket and then read, it slowed down to my 1 sec per 64K. If I specify a buffer (something big but less than 64K ... IP packet size?) then I am back in speedy territory. The unbuffered mode seems almost like it is sending the data 1 char at a time AND this is the default mode used in SocketServer and subsequently BaseHTTPServer ... This is on solaris 7, python 1.5.2. Anyone else found this to be a problem or am I doing something wrong? andy

Re: Python/Java OOish type question
by jurgen.defurne＠philips.com Aug. 31, 2000

I think that Java as an OO language is implemented well, that is You define a class as an aggregate of functions and data. Then, in the compilation, you will have a table with pointers to the defined functions and a system which for instantiating your objects. Your object will consist of the following a parts : a) A pointer to the table of your class methods b) Space for the object members So, the overhead for class functions in each method, should at most be one pointer. I say at most, because this pointer is only needed in case of virtual functions. If the system can be complete statically typed, then you don't need even this pointer in the created objects. Jurgen

OpenSSL & Python -the Saga Continues

Ok... I finally installed OpenSSL and Python Correctly. I you saw in my previous posting I was having some trouble. Now I want to see if you one has seen this error before... my code: #!/usr/local/bin/python import urllib, urlparse, string, time, httplib, os, socket, mimetools def get_temp2(): url = httplib.HTTPS('login.isend.com') url.putrequest('GET', '/') url.putheader('Accept', 'text/html') url.putheader('Accept', 'text/plain') url.endheaders() errcode, errmsg, headers = url.getreply() print ("error code = %s" % errcode) f = url.getfile() data = f.read() f.close() print data and this is the error: Traceback (most recent call last): File "/home/kyoung/test.py", line 45, in ? get_temp2() File "/home/kyoung/test.py", line 25, in get_temp2 url = httplib.HTTPS('login.isend.com') File "/usr/local/lib/python1.6/httplib.py", line 84, in __init__ if host: self.connect(host, port) File "/usr/local/lib/python1.6/httplib.py", line 213, in connect ssl = socket.ssl(sock, self.key_file, self.cert_file) socket.sslerror: SSL_connect error Thank you for your time.

How to build a vector from two floats?
by Fredrik Lundin Aug. 31, 2000

Aug. 31, 2000

Hey! I am experiencing problems when I want to build a vector out of two floats. I am routing two SFFloats from a WRL-file to the python script. The function looks like this: class TextureScale(TypedField(SFVec2f,(SFFloat,SFFloat))): def evaluate(self, inputs): return inputs[0].get(),inputs[1].get() texturescale = TextureScale() Shouldn't the return be of the type SFVec2f with two SFFloat in x- & y-pos?

Python Problem - Important!
by Jon LaCour Aug. 31, 2000

Aug. 31, 2000

I am beginning development of a very large web application, and I would like to use Python (no, Zope is not an option). PyApache seems to be my best bet, but there is a MASSIVE problem with Python/PyApache that prevents it from being even marginally useful to me, and to most major software companies. My product requires database access, and the database module that I use for connecting depends on a library called mxDateTime. This is a very robust library that is in use all over our system (it has never given us problems). Yet, when I use PyApache to connect to a database, I have major issues. I have seen this same problem posted to this newsgroup and to the PyApache mailing list several times from over a year ago, and it appears to be unresolved. The essential problem is this: the second time a module is loaded, Python has cleaned up its dictionaries in its cleanup mechanism, and does not allow a re-init. With mxDateTime this gives an error: "TypeError: call of non-function (type None)" Essentially, this is a major problem in either the Python internals, or in PyApache. After tracing the previous discussions on this issue, it appears that this is a Python problem. I am very serious when I say that this problem *must* be resolved before Python can be taken seriously for use in web applications, especially when Zope is not an option. I require the use of Apache's security features, and several other Apache extensions. If anyone knows how to resolve this issue, or can even point out a way that I can resolve this *myself* I would love to hear it. This is the single stumbling block standing in the way of my company converting almost entirely to Python development, and I am hoping that python developers will take this bug and smash it quickly.
