efficient intersection of lists with rounding
Hi, I have to lists that I need to find the common numbers (2nd rounded to nearest integral) and I am wondering if there is a more efficient way of doing it. >>> a= [(123,1.3),(123,2.4),(123,7.8),(123,10.2)] >>> b= [(123, 0.9), (123, 1.9), (123, 8.0)] >>> [ (i,round(j)) for i,j in a for l,m in b if (i,round(j)) == (l,round(m))] [(123, 1.0), (123, 2.0), (123, 8.0)] >>> This works but a and b can be in the order of 30K long. A couple of other bits of info. - a and b are ordered smallest to largest (could bisect module be used?) - in the future I will want to round the second number of closest 0.25 rather than whole number. Would the sets module be more efficient? I'm using python 2.3. Thanks for any ideas. Regards, Gordon Williams -- http://mail.python.org/mailman/listinfo/python-list

Thanks for all your suggestions. I've tried each one with lists of 1K, 10K
and 30K long and tabulated the results below. Run with profile on W2K,
python 2.3.2, 1GHz Athlon.
1K, 10K and 30K long (seconds per call)

t4= 0.016, 0.190, 0.749
t5= 0.015, 0.224, 0.773
The non-set algorithims (t1,t3) came out the winners (maybe due to the
conversion of the set to a sorted list. I didn't look into it any farther.)

Web sites can't send you stuff unsolicited, and most of them have enough stake in their reputation to keep the obnoxious stuff off of them, since if they have viruses chances are you can't trust buying anything from them. "web bugs" aren't a problem with web sites since the server logs log *all* the hits, and they don't have to use hidden ones.

However, from some of the other replies, it seems that your suggestion involved identification of the sender with digital signatures. I think one necessary function of email and USENET is that it should allow you to SAFELY communicate with strangers or, worse, people you know but do not trust at all, and who are known to be malicious, if you wish to do so, especially since meeting in person might invoke the use of weapons of mass destruction (like, for example, me and my hypothetical ex-wife). For example, George W. Bush ought to be able to exchange email with Osama Bin Laden without risking revealing nuclear launch codes. Hitler and Winston Churchill should have been able to exchange email (had it been available during World War II) without revealing state secrets accidentally. I ought to be able to exchange email with my boss without his being able to track if/when I read it. I ought to be able to communicate with the Direct Marketing Association to get them to take my name off a mailing list without risking spyware installation or revealing my credit card numbers. Union leaders and management should be able to negotiate by email without unwittingly leaking information. HTML is *mostly* dangerous. (links. Javascript. references to other files on the user's computer. Forms.) It's a lot more than text formatting. I suggest that if you want a text formatting language, start with *TROFF* and take out the parts that refer to other files. As far as I know, troff doesn't have any networking references in it. Lots of people probably hate troff, but it's a better start than HTML. Gordon L. Burditt -- http://mail.python.org/mailman/listinfo/python-list

If you take all the dangerous stuff out of HTML, like:

you'd have very little left. I suggest that for formatted text,
TROFF would be a better start.

What possible harm can reading and setting cookies do? I had Javascript may be able to set cookies even if they are turned off by the normal mechanism of setting cookies. Even if that isn't the case, cookies are supposed to be domain-specific and a cookie from site A (which might have a session ID for an active login session, or login credentials for site A) should not be sent to site B. Javascript can apparently make its own URLs and send anything it gets its hands on to any site it wants to. The existence of a cookie from site A shouldn't be revealed at all to site B (or to Javascript from site B), regardless of what it contains. >always thought they were carefully and successfully designed to be >harmless. That's not personal information in your cookies. That Some websites *DO* put personal information in cookies. They don't all just use randomized session identifiers. Some of them store login credentials for a site (not just a currently active session, but permanent login credentials. That might not be "personal" the same way a SSN or credit card number is, but you could still do damage with it). A lot of the popularity of Javascript comes from the ability to steal information from the client computer that normal HTML does not give access to (e.g. screen/window size, email address, IP address as seen by the client (because of NAT and proxies, might not be the same IP as seen by the server), MAC address, browsing history, Windows serial number, Pentium CPU serial number, etc.) >information is set by websites for the sole purpose of being read by >websites. *BY THE WEBSITES THAT SET THEM*, not by all websites. The "domain" parameter for setting cookies has been in there since the beginning of the standard for cookies. If a marketer wants a piece of information, then I don't want him to have it, even if it's something like "I visited and then went to " even if there's no identification of who "I" is. >Plus, I'm pretty sure that browsers have always allowed us to >disable cookies.

Before worrying about the possible bugs in the implementations,
worry about security issues present in the *DESIGN*. Email ought
to be usable to carry out a conversation *SAFELY* with some person out
to get you. Thus features like this are dangerous (in the *design*,
not because they *might* hide a buffer-overflow exploit):
- Hyperlinks to anything *outside* the email in which the link
resides ("web bugs").
- Javascript.
- Any ability to automatically generate hits on sender-specified
servers when the email is read.
- Any kind of return-receipt mechanism that doesn't require initiation
by the recipient.
- Any kind of return-receipt mechanism that indicates that the
message got past the spam filter.

Generic utility class for passing data
I'm wondering if this is might be bad practice. Sometimes when I need to pass around several pieces of datum I will put them in a tuple, then when I need to use them in a receiving function I get them out with subscripts. The problem is that the subscript number is completely meaningless and I have to remember the order I used. As an alternative I was considering using a dummy class like this: class Dummy: pass Then when I need to pass some related data, Python lets me do this: prefill = Dummy() prefill.foreground = 'blue' #"foreground" is made up on the fly prefill.background = 'red' prefill.pattern = mypattern return prefill Now I can access the data later using meaningful names. Is this going to cause problems somehow? Should I rather go to the trouble of creating more substantial individual classes for every grouping of data I might need to pass (with __init__'s and default values and so on)? Should I just stick with subscripted groupings because of the overhead? -- http://mail.python.org/mailman/listinfo/python-list

There is no O_DIRECT or fcntl() in Standard C.
fcntl() operates on an open file descriptor, and the file descriptor
for stdin is 0. Two calls to fcntl(), one with F_GETFL and one
with F_SETFL, would do what you want.
I'm not sure why you want to do that, though. It's not going to
get you character-at-a-time I/O, if that's what you want.

Does O_DIRECT perhaps invoke some of the restrictions of "raw"
device files, where the current offset and transfer size must be a
multiple of some block size? (I don't see any mention of that in
FreeBSD's documentation.) What is the value of blocksize at the
time of the traceback above? I suggest keeping it well under 2G.

I just tried to pickle.load() a .pyc and it failed with a 'KeyError' exception - however that works. It might do that every time, it might not. Regarding b., if I type check I simply get the 'instance' type, which doesn't get me all of the way there because I might have an instance of the wrong class.

Using MSMQ on Windows (and Navision)
I'm investigating getting Microsoft Navision to do stuff from a Python
script. The recommended way seems to be to use message queues (MSMQ).
I can get Navision to send a message to itself fine. I found a couple
of code example in an ancient message in this newsgroup. The send.py
one I changed to the following:
from win32com.client import gencache
msmq = gencache.EnsureModule('{D7D6E071-DCCD-11D0-AA4B-0060970DEBAE}',
0, 1, 0)
qi = msmq.MSMQQueueInfo()
qi.PathName = ".\\testqueue"
try:
myq = qi.Open(msmq.constants.MQ_SEND_ACCESS,0)
except:
qi.Create()
myq = qi.Open(msmq.constants.MQ_SEND_ACCESS,0)
if myq.IsOpen:
msg = msmq.MSMQMessage()
msg.Priority = 3
msg.Body = "Hello World!"
msg.Label = "Navision MSMQ-BA"
print len(msg.Body)
print msg.BodyLength
msg.Send(myq)
myq.Close()
And the read one all I changed was the queue name.
# read.py - reads from the queue
# following bit generated via "makepy -i" ...
# Use these commands in Python code to auto generate .py support
from win32com.client import gencache
msmq = gencache.EnsureModule('{D7D6E071-DCCD-11D0-AA4B-0060970DEBAE}',
0, 1, 0)
qi = msmq.MSMQQueueInfo()
qi.PathName = ".\PyQueueX"
myq = qi.Open(msmq.constants.MQ_RECEIVE_ACCESS,0)
if myq.IsOpen:
msg = myq.Receive()
print " body: %s" % msg.Body
print "label: %s" % msg.Label
myq.Close()
-
They can send messages to each other fine.
The read.py can receive messages from Navision fine.
But messages sent to Navision (after changing the msg.Label to "Navision
MSMQ-BA") show up as empty messages (nothing in the body).
I can only see two differences between messages generated from Navision
and messages generated send.py.
1) Messages from Navision have something in the "Administration" bit
when you look at the message's properties in computer management (Format
name: PUBLIC=2bc802b2-7778-42c1-bc30-28caca20d974, Name:
it2-new\nsadminreceivequeue). Where as ones from send.py don't.
2) Every character in the body of messages sent from send.py has a 0
value character after them (ie in hex 48 00 65 00 6C 00 6C 00 6F 00 20
00 57 00 00 6F 00 72 00 6C 00 64 00 21 00)
Adding a print msg.BodyLength just before the msg.Send(myq) yields 24
for a 12 character message.
I'm assuming it is 2), coz it's just weird (unicode?).
Any ideas?

Tkinter - Resizing a canvas with a window
I'm trying to get my canvas to resize to fill its frame within a window,
but I can't figure out how to handle the callback data from the window's
properly. It has very strange behavior - resizing randomly
or growing by itself, shrinking to 0. The following works passably but
jumps around at random if you move the window and goes nuts if you add
the button (watch any wrapping):
from Tkinter import *
class testApp2:
def __init__( self, master ):
self.ma = master
self.f = Frame( self.ma )
self.f.pack()
self.cv = Canvas(self.f, width=25, height=25, bg='red')
self.cv.pack()
#self.b1 = Button( self.f, text='hello', command=None )
#self.b1.pack(side='bottom')
self.ma.bind('', self.resize )
def resize( self, event ):
#print '(%d, %d)' % (event.width, event.height)
self.cv.configure( width = event.width-4, height = event.height-4 )
root = Tk()
app = testApp2(root)
root.mainloop()

Re: Tkinter - Resizing a canvas with a window
Thanks you very much. I found something interesting though, the canvas's
width and height properties are not updated when it is resized by its
packing. Looks like an oversight to me, but I've just demonstrated that
I don't have a complete grasp of Tk, so... I can use a Configure
callback to keep track of the values, however.
from Tkinter import *
class testApp3:
def __init__( self, master ):
self.ma = master
self.f = Frame( self.ma )
self.f.pack(fill=BOTH, expand=YES)
self.cv = Canvas(self.f, width=125, height=125, bg='red')
self.cv.pack(fill=BOTH, expand=YES)
self.b1 = Button( self.f, text='Hello', height=1, width=10,
padx=0, pady=1, \
command = self.howbig )
self.b1.pack(side=BOTTOM, anchor=S, padx=4, pady=4)
self.cv.bind('', self.resize )
def howbig( self ):
print self.cv['width'], self.cv['height']
print self.cvw, self.cvh
def resize( self, event ):
print '(%d, %d)' % (event.width, event.height)
self.cvw, self.cvh = event.width-4, event.height-4

Some sites do much worse than that. If you have cookies off, they
cause an infinite redirect loop. Sometimes my browser manages to
detect this after a few minutes and shut it off, and sometimes it
doesn't (usually on different sites). I think I can manually get
out of this with the STOP button, but until I do, it likely causes
a lot of useless load on the web site.

thread safe SMTP module
I believe that I've seen this discussed previously, so maybe there's
some interest in it. I wrote a threaded mail filtering framework a
while ago, and one of the modules does address verification via SMTP.
Since smtplib.SMTP uses blocking IO, it can block the whole
interpreter. Sometimes the whole thing would stop working indefinitely.
I'm now aware that Twisted offers a non-blocking SMTP class, but I
didn't really want to make that a dependency of the address
verification. I ended up subclassing the smtplib.SMTP class and
rewriting the functions that do I/O. Perhaps someone who doesn't want
to install Twisted will find this class useful, someday. It doesn't
support TLS, but it is otherwise a thread-safe SMTP class.
class ThreadSMTP(smtplib.SMTP):
"""SMTP class safe for use in threaded applications.
This class reimplements the SMTP class with non-blocking IO,
so that threaded applications don't lock up.

Nevertheless, among the caveats listed at http://docs.python.org/lib/module-thread.html is: "Not all built-in functions that may block waiting for I/O allow other threads to run.

I subclassed smtplib.SMTP and replaced only the lines of code that had to do with blocking IO (connect, send and receive operations). Beforehand, python would occasionally lock up. Having made those changes, python stopped locking up. I think the problem was pretty well apparent. I can't pin it down to which one of those three operations was at fault, and it may be that only one was. However, when I use non-blocking IO, the application works. When I used smtplib.SMTP, it didn't. I'm open to other explanations. -- http://mail.python.org/mailman/listinfo/python-list

This note is included in the socket documentation, regarding "timeout mode": http://docs.python.org/lib/socket-objects.html "A consequence of this is that file objects returned by the makefile() method must only be used when the socket is in blocking mode; in timeout or non-blocking mode file operations that cannot be completed immediately will fail." smtplib.SMTP uses file objects when reading SMTP responses. If I used setdefaulttimeout(), then the socket would be in timeout mode and the above note would be applicable.

Ah, I forgot I have Cygwin installed, so I do have tail. Unfortunately Windows will not let most programs save to the file while tail is watching it, and when I force it with vim :w! the output from tail -f does not update. Maybe I'm using it wrong.

ClientForm .click() oddity
I've written a script using ClientForm to automate opening and closing
ports on my Linksys router. It works, but I wonder if there isn't a
better way to do it.
The problem is that the list of arguments in the request generated by
.click()ing the form is incomplete and I have to edit it manually. The
Submit button on the form is created with the following code:
document.write("");
Which calls this function in the form source:
function to_submit(F)
{
F.submit_button.value = "Forward";
F.action.value = "Apply";
F.submit();
}
Simply .click()ing on the form does not properly fill in
submit_button=Forward&action=apply, however. The arguments are there but
with no values.
Is this because ClientForm doesn't run javascript, or is there a way to
determine and fix these values without manually editing the .data string
of the Request with values I have to find on my own?

I agree that it is confusing, however. IMO the confusion could be lessened if the function with the current behavior were renamed 'telescope' or 'compact' or 'collapse' or something (since it collapses the iterable linearly over homogeneous sequences.)
