It gets even simpler: cursor objects are iterable after the `execute()`
call. So you don't need the number of rows::
gert.excecute('select * from person')
for row in gert:
print row
gert.close()

Don't think about clicking a coordinate or typing something; think about the actions on the page. e.g. to fill in a field on a form you'll want something like: ie.document.forms[formname][fieldname].value = 'whatever' to click a button call its click method e.g. submit = ie.document.forms[0]['submit'] submit.focus() submit.click() Check out the documentation at msdn.microsoft.com for the application, document, form etc. objects.

Linking in a Linux environment
Bonjour, We have implemented Python as an "embedded script language" in our NLP application, XIP which a grammar rule engine written in C++ and available as a library. We have also developped a GUI in Java, which is linked to this XIP library, to simplify the development of NL grammars. JAVA GUI IDE Library: XIP (C++) Python Modules can be called from grammar rules Now we have the following problem, when we try to execute a Python script from a grammar in a Linux environment, the system fails when this Python module tries to import basic modules like "math" for instance. The system returns a "PyExc_OverflowException undefined variable" error. This problem only occurs on Linux platforms, we do not have any problems on Mac OS and on Windows. We have linked our NLP library with Python 2.4.4, and we have tried many different manipulations to solve this problem. We have tried to link with the static and the dynamic Python library, without any success. Searching the WEB, we have discovered similar problems, but none of the proposed solutions actually worked. For instance, some people wrote that the problem was to due to the compiling options of our Python library; we checked the Makefile for these options, which we found to be already there. We also tried to modify the dlopen options, as suggested, through the specific dlopen operations in the Python corresponding library. NOP... However, the use the Python 2.5 dynamic library seems to solve most of these problems, which would be ok, if people would accept to switch to a version that is quite new. Halas, this is not that simple... I still do not have any clear answer about what is going on. If someone could help me on this one, I'll be really grateful... :-) Merci d'avance, Claude -- http://mail.python.org/mailman/listinfo/python-list

Program eating memory, but only on one machine?
Hi Everybody: I'm having a difficult time figuring out a a memory use problem. I have a python program that makes use of numpy and also calls a small C module I wrote because part of the simulation needed to loop and I got a massive speedup by putting that loop in C. I'm basically manipulating a bunch of matrices, so nothing too fancy. That aside, when the simulation runs, it typically uses a relatively small amount of memory (about 1.5% of my 4GB of RAM on my linux desktop) and this never increases. It can run for days without increasing beyond this, running many many parameter set iterations. This is what happens both on my Ubuntu Linux machine with the following Python specs: Python 2.4.4c1 (#2, Oct 11 2006, 20:00:03) [GCC 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import numpy >>> numpy.version.version '1.0rc1' and also on my Apple MacBook with the following Python specs: Python 2.4.3 (#1, Apr 7 2006, 10:54:33) [GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import numpy >>> numpy.version.version '1.0.1.dev3435' >>> Well, that is the case on two of my test machines, but not on the one machine that I really wish would work, my lab's cluster, which would give me 20-fold increase in the number of processes I could run. On that machine, each process is using 2GB of RAM after about 1 hour (and the cluster MOM eventually kills them). I can watch the process eat RAM at each iteration and never relinquish it. Here's the Python spec of the cluster: Python 2.4.4 (#1, Jan 21 2007, 12:09:48) [GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-49)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import numpy >>> numpy.version.version '1.0.1' It also showed the same issue with the April 2006 2.4.3 release of python. I have tried using the gc module to force garbage collection after each iteration, but no change. I've done many newsgroup/google searches looking for known issues, but none found. The only major difference I can see is that our cluster is stuck on a really old version of gcc with the RedHat Enterprise that's on there, but I found no suggestions of memory issues online. So, does anyone have any suggestions for how I can debug this problem? If my program ate up memory on all machines, then I would know where to start and would blame some horrible programming on my end. This just seems like a less straightforward problem.

Last time I checked there is no > such thing as SSH-over-HTTP. Are you sure that is possible? He's referring to the HTTP CONNECT method, which can tunnel arbitrary TCP connections, not just HTTP. The IETF draft for this is titled "Tunneling TCP based protocols through Web proxy servers". AFAIK, there are no Python modules which support that. The protocol itself is fairly simply though, so it shouldn't be too hard to write your own wrapper or proxy for the client side. Things get a little more complicated if you have to authenticate with the proxy first. -- http://mail.python.org/mailman/listinfo/python-list
GetBoundingMetrics
Hi,
I have been moving from Windows XP to Debian Etch. Most of my
Python scripts work fine with minor modifications. However, I have a
script that launches a browser and goes to various sites using the
Python module webbrowser.open ("url-goes-here")
On Debian Etch, Firefox (or IceWeasel, I guess) opens the sites, but
back in the
commandline window I get repeated messages that say:
GetBoundingMetrics (char *)
Anybody know what's causing that? I don't get it if I just launch
firefox from the commandline. Only when I use the Python module.
Thank you,

you can use urllib2 python module:
# TestGoogle.py
#
import urllib2
#
f = urllib2.urlopen('http://www.google.fr/images/nav_logo.png')
data = f.read()
f = file('nav_logo.png', 'w')
f.write(data)
f.close()
in your case, may be parameters are passed thru url to get a particular
barcode image (http://myserver/myapplication/barcode?format=xxx&id=yyy
etc. ...).
for authentication, if any, it needs a little more sophisticated coding.

Is there a better way to implement this:

This function just runs for the specified number of seconds and returns. However, before it returns, throws an exception. c) If test() is still running when abort() is finished, ftimed() should catch the exception and return. It is catching the exception, however it continues running the function. Why does it continue and not return? What am I missing, or is there a better way to implement this (having ftimed() return when the abort-timer time is exceeded? import time, thread, sys thread_finished = "MAX RUN TIME EXCEEDED!" def abort (seconds): start_time = time.time() while ((time.time() - start_time) < seconds): time.sleep(0.01) print "script run time exceeded max_run_time of", seconds, "seconds." raise thread_finished return def test(): i = 0 while (True): time.sleep(1) print "HELLO", i i+=1 def ftimed (func, seconds): thread.start_new_thread (abort, (seconds,)) try: func() except thread_finished: print "Timeout" return ftimed (test, 30) print "Script finished" It presently generates the following output: $ python ./testthread.py HELLO 0 HELLO 1 HELLO 2 HELLO 3 HELLO 4 HELLO 5 HELLO 6 HELLO 7 HELLO 8 HELLO 9 HELLO 10 HELLO 11 HELLO 12 HELLO 13 HELLO 14 HELLO 15 HELLO 16 HELLO 17 HELLO 18 HELLO 19 HELLO 20 HELLO 21 HELLO 22 HELLO 23 HELLO 24 HELLO 25 HELLO 26 HELLO 27 HELLO 28 HELLO 29 script run time exceeded max_run_time of 30 seconds.

Here is a snipped that show a "software terminateable threading TCP
socker server". The "server" object is a SocketServer instance,
server_stopped is a threading.Event instance. You should also import the
"select" module.
srvfd = server.fileno()
while not server_stopped.isSet():
ready = select.select([srvfd], [], [], 1) # Give one second
for incoming connection so we can stop the server in seconds

Re: closing a "forever" Server Socket
Oh my God! it's really so complicated?
3 modules (threading, SocketServer, select) only for design a way to
shutdown a TCP server
...but they told me that python was easy... :)
I'm working on a simulator and I have a monitor server that collects
information. I can shutdown it using Ctrl-C from the keyboard but for
my purpose could be very nice if I introduce a timer. So I could launch
my monitor like this:
./monitor 100
and my monitor will run for 100 seconds. For this I'm using the Timer
class provided by threading module, I have implemented a function like
this:
def shutdown():
sys.exit()
but it doesen't work because the server remain alive...maybe
SocketServer create immortal server...
I need only to close my application, there is a way to force the server
thread to close?
thanks!

Re: Program eating memory, but only on one machine?
I had a similar problem with an extension module on Solaris years ago. My problem at that time: I requested memory and released it and requested more memory in the next step and so on. The reason that the memory was eaten up: An answer out of this group was that the operating system doesn't release the memory space because it assumes you will need it soon again. The memory will only be released with the end of the process. The solution was always to request memory for the largest array the process will demand and it worked for me.

Yes, Python is easy. The language is very clear, and you do not need to install third party modules in order to create a server. :-) Of course the easiest way is to call serve_forever. Isn't it easy? The other way is to implement your own message handling loop. The SocketServer is flexible enough to do this; and I don't think it is complicated. 7 lines of code will allow you to stop the server safely from anywhere, even from other threads. Try to implement the same in C or Delphi... > but it doesen't work because the server remain alive...maybe > SocketServer create immortal server... > I need only to close my application, there is a way to force the server > thread to close? > In pure Python, no. Python threads are "cooperative". In other words, they cannot be terminated from outside. A thread will stop after the execution exits its "run" method. (You can, of course terminate the tread with an operating system function, but it is not recommended.) Here is a class that can be stopped with an event: import threading stop_requested = threading.Event() class SoftWaitThread(threading.Thread): """SoftWaitThread can wait for a given time except if the thread was asked to terminate itself.""" def waitsome(self,amount=10): """Wait the specified amount of time. This can be terminated by stop_requested within 0.1 seconds.""" for idx in range(int(10*amount)): time.sleep(0.1) if stop_requested.isSet(): break Then you can do this: class MyServerThread(SoftWaitThread): def run(self): server = MySocketServerClass() srvfd = server.fileno() while not stop_requested.isSet(): ready = select.select([srvfd], [], [], 1) if srvfd in ready[0]: server.handle_request() else: pass And then: import time def main(): sth = MyServerThread() # Create your thread sth.start() # Start handling requests in another thread try: time.sleep(TIMEOUT_IN_SECONDS) # Wait... finally: stop_requested.set() # Request the server thread to stop itself sth.join() # Wait until the server thread stops print "Stopped." You could start several threads and request them to stop with the same event. I hope this helps.

AES and Credit card number encryption
I browsed this subject and thought I might use the
'AES' cypher scheme to do this. Would this be
a good choice?
I came across a "Python Cryptography Toolkit"
http://www.amk.ca/python/code/crypto
which has a nice AES implementation, but in
the example, a simple string is passed as the
key:
obj=AES.new('abcdefgh', AES.ECB)
So my real question is, how do I go about
generating the best key. Isn't the length
supposed to be a 2^n bits, and soforth?
Thanks,
Tobiah

Building extensions with vc8

I'm not sure what precisely "used memory" is, most likely it is the working set of the process, i.e. the amount the number of physical pages that are allocated for the process. That is typically much smaller than the address space, since many pages will be paged out (or not yet read in at all). You need to display the virtual address space in the task manager to determine how much address space the application is using. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list

AES key length is your choice of 128, 192, or 256 bits. In practice 128 bits (16 bytes) is fine and is what most people use. You should use 16 completely random bytes.

To my knowledge, no. There might be virtual memory quotas, but I don't think Windows supports such a concept. More likely, this is entirely unrelated to the mmap issue. I would guess that the machine on which the problem occurs is close to exhausting its swap file (because of other activities in the system), so Python occasionally manages to exhaust the swap file, through regular allocations (memory-mapped files don't contribute to swap file usage, as they have their own disk-backing, namely in the file being mapped).

To get the facts straight: it *might* be possible to build an extension with msvc8 (thus linking with msvcr8.dll); this should work as long as the extension doesn't use any API that is forbidden for the mixed-CRT case. Only a source inspection of the extension module can tell whether there is any risky code. > Since the "free" compiler from Microsoft is now VC8, I *assume* this will > be the new method.

Virtual address space fragmentation isn't affected by the amount of physical memory in your system. A system with 64MB of RAM might be able to map a 400MB file while system with 3G of RAM might not be able to map it because of how DLLs got loaded in to the process. > Actually I am less concerned about whether a MemoryError > is raised or not in this case and more about the fact that even if > there's no exception, the program may suffer from severe thrashing due > to constant swapping. Well, that's what you're asking for when you use mmap. The same mechanism that creates virtual memory using a swap file is used to create a virtual memory mapping of your file. When you read from the mmap file pages from the file a swapped into memory and stay in memory until they need to be swapped out to make room for something else. If you don't want this behaviour, don't use mmap. Ross Ridge -- http://mail.python.org/mailman/listinfo/python-list

You are confusing dynamic typing with weak typing. Weakly typed languages (such as BASIC perform) such implicit conversions. However, Python is dynamically and strongly typed. With dynamic typing, the type information resides with the actual object and not with the name referring to it. That simply means that the type cannot be determined till the object is actually created (i.e till runtime). But once created, the object does have a type. So you will need to explicitly convert yourself. In this case with int_value = int(string_value) Ravi Teja. -- http://mail.python.org/mailman/listinfo/python-list

But when put it under timerit.Timer, like this:
t = timeit.Timer("func1()","")

# want to time how long it takes to run 'func1' 10 times, I get an

I've noticed it on Ubuntu Linux, Mac OSX, and earlier today on Sun Solaris. What do I need to do to install / configure readline? -- http://mail.python.org/mailman/listinfo/python-list

Have you changed your terminal (either the program itself or its config) so that it is no longer sending the correct codes? When you hit the arrow key, what happens? Do you just get nothing at all, or do you get control characters appearing? e.g. ^Z or similar. -- Steven D'Aprano -- http://mail.python.org/mailman/listinfo/python-list

Because the code in timeit is running in a different namespace. You have
to import your function first. That's what the setup parameter is used for.
Here's the hard way:
t = timeit.Timer("func1()", """def func1():
#do something here
return result
""")
Here's the easy way:
t = timeit.Timer("func1()", "from __main__ import func1")

Everything works for the bash shell and common lisp. It's just python acting up. > When you hit the arrow key, what happens?

Re: arrow keys don't work
It looks like I got readline working. Thanks for the help! -- http://mail.python.org/mailman/listinfo/python-list
