POP connection timeout.

Hi

I am have written an application that queries a POP mailbox and
downloads messages. When the application tries to connect to the mail
server, but takes too long (eg. longer than 60 seconds) I want to have
it time out.

Something like

try:
pop = poplib.POP3(POPHOST, POPPORT)
except someerror, err:
print "Connecting to mail box has timed out:\n", err

I know that in python 2.5 I could pass an additional timeout parameter
to the above statement ( ie: pop = poplib.POP3(POPHOST, POPPORT,
TIMEOUTINSECONDS), but I am using python 2.4.

Can anyone help me implement this timeout functionality.

wxpython ms-dos black window popping up in background   (245 Views)
platform: windows xp professional, python 2.5, wxpython When I double-check on my program file test.py (for simplicity I'll be using this code below), I see the window just fine. But the ms-dos black window pops up in the background. On Linux, no issues at all. How can I get rid of that ms-dos black window in the background something I need to add to my code a setting to adjust in windows thanks in advance. #!/usr/bin/python import wx appwx = wx.App() frame = wx.Frame(None, -1, 'test.py') frame.Show() appwx.MainLoop()
pop langs website ranking   (107 Views)
In February, i spent few hours researching the popularity of some computer language websites. (The message can be found here: http://xahlee.org/lang_traf/lang_sites.html http://community.livejournal.com/lisp/42778.html http://groups.google.com/group/comp....c87899c2668f4c ) In that post, one question i puzzeled over is why PaulGraham.com's traffic is surprisingly high, since the site doesn't seems to host forums, computer lang documentation, or wiki type of thing, yet it is ranked higher than perl.com, which actually host online forum, faq, documentation, news etc. I wrote: ------------ paulgraham.com 48153 (lisp bigwig, but huh) Perl.com 49104 xahlee.org 80060 Me! ------------- Compared to xahlee.org, it's a ranking difference about 32 thousand! Today, while checking the web ranking site alexa.com, they seems to have updated their ranking algorithm to be more fair, as opposed basing it solely on a browser toolbar that users install. So i went over to my essay and checked the ranking again of sites i reported. I have spent only about 20 min to cursorily go thru the sites i reported before. It appears that, in general, the order of sites that i listed ROUGHLY remains unperturbed, but the specific ranking ordinal has changed rather significantly. However, there's a big surprise. My website is now actually ranked higher than PaulGraham.com ! LOL. Paul Graham Bah humbug. Painters == Hackers Fuck ya ass. Arc Eat shit and die. PS: not having no confidence of myself, but i note that xahlee.org is now marginally ranked higher than perl.com and perl.org, both of which host forum/blog/wiki, news, docs, etc., while my website don't do any of these and is all static html pages. For those unflagging, alternative web ranking site is http://ww.quantcast.com/ . I'll be doing some research sometimes soon on this.

"env" parameter to "popen" won't accept Unicode on Windows - minorUnicode bug   (86 Views)
I passed a dict for the "env" variable to Popen with Unicode strings for the dictionary values. Got: File "D:\Python24\lib\subprocess.py", line 706, in _execute_child TypeError: environment can only contain strings It turns out that the strings in the "env" parameter have to be ASCII, not Unicode, even though Windows fully supports Unicode in CreateProcess.

pop langs website ranking   (106 Views)
while doing my website's traffic report, i did some research on major computer lang or tech website ranking. Here's the result ranked by alexa.com (some non-lang tech sites are given just for comparison): Php.net 550 (largely due to online doc and forum) sun.com 900 (java doc and forum) java.com 1122 slashdot.com 1223 (forum) Mysql.com 1296 (online doc, forum) gnu.org 7328 (massive docs, mailing list archives) wolfram.com 9065 (online doc, mathworld etc) Python.org 9410 (python doc and prob forums) Perl.org 26067 (perl doc, forum) paulgraham.com 48153 (lisp bigwig, but huh) Perl.com 49104 xahlee.org 80060 Me! haskell.org 118703 novig.com 130568 (lisp bigwig) franz.com 292598 lispworks.com 377906 (common lisp doc) Gigamonkeys.com 529551 (pop common lisp book) schemers.org 880284 The list is not that surprising. Many top ones are due to the popularity of the lang, but also because their site hosts the lang's documentation and discussion forum (or wiki,blogs). Hosting a web forum are likely to increase traffic some 10 or 100 fold. Questions: paulgraham.com is unusually high. What's up with that python.org at 9k seems also unusally high, compare that perl.org with online doc and forum is only 26k. Python.org has mailing list archives... maybe blogs too but am not sure it has forums... still the gab seems surprising. Even perl is not much talked about these days, but i'm guessing its market share is at least still 10 or 100 times of python... If any one so wishes, add entries to the above list.

os.popen does not seem to catch stdout   (139 Views)
, I've been banging my head against this for a day, and I can't take it anymore. It's probably a stupid error, but I don't see where. I'm trying to use Python to call an external program, and then catch and process the output of that program. Seems simple enough. The command I'm trying to run, in the test, is: "/Users/zane/svn/stress/satstress/satstress -r1.561e+06 -a5 -s45000 - e0 -R6.709e+08 -g1.31472 -m1.8987e+27 -Q57100.1 -n0.333355 -Y9.29881e +09 -k1e+22 -Z1.19173 -z-6.293e-05 -V0.309434 -v-2.903e-05 -W1.81305 - w-0.00418645 -U0.474847 -u-0.00276624 -C /tmp/18_tmp.gen -b 60" When I run it at my zsh prompt, I get the expected output. If I let ss_cmd equal the above string within ipython (or the standard python interactive interpreter): ss_outlines = os.popen(ss_cmd).readlines() ss_outlines contains the same output I saw when I ran the command at my zsh prompt, one line per list element, as expected. However, when I try doing the same thing from within a program, it fails. ss_outlines is an empty list. I've tried using subprocess.Popen(), and subprocess.call(), and subprocess.check_call(), and all have yielded similar results. I did find, however, that the return value python is getting from the program I'm calling is different from what I get at the command line (I get 0, python gets -11). Does this ring a bell for anyone I'm using Python 2.5.1 on a Mac running OS X 10.5.

How popular is Django ?   (96 Views)
Hi! I was surprised when I did a google-groups search for python, ( http://groups.google.com/groups/sear...=Search+Groups ) it shows these groups: comp.lang.python with about 11000 users, and second, Django users Discussion group for Django users. Django is a high-level Python Web ... with 6500 members !!!! I cannot believe that django is *that* popular ... where am I going wrong Cheers, Sebastian Haase
wx.ToplevelWindow.SetIcon: Native MS Windows error dialog pops upin wxPython app, no exception raised, no stack trace   (137 Views)
, I wrote a small program that works uses wxPython. The same application works on Linux and Windows. When I start it from MS Windows, I see this error message appearing each time I open a window: --------------------------- Warehouseclient Error --------------------------- Can't load image from file '': file does not exist. --------------------------- OK --------------------------- The message box itself is a native MS Windows dialog. Otherwise the program works fine, just here is this annoying message. There is no exception raised in the Python program. Nothing printed on console. I figured out that this happens only when I set the icon of the window using this code: self.SetIcon(icon) However, the error dialog is not displayed right after the SetIcon call and no exception is raised. The dialog is displayed after __init__ has been called, and probably before EVT_SHOW gets called. Documentation of SetIcon (http://wxwidgets.org/manuals/stable/...lwindowseticon) says that it is safe to delete the icon after calling this function. Now here are the wreid things: 1. The icon is displayed correctly in the left top corner, so where is the error 2. The error message complains about a file. What has wx.ToplevelFrame.SetIcon do with files I'm using: Windows XP Professional, Python 2.5, wxPython 2.8
mode parameter in popen2-4   (110 Views)
In the popen docs, a file like object is returned, and may be read to or written to depending on the 'mode' parameter ('r', or 'w'). Why is the mode parameter needed for popen2 and greater, when both a stdin and stdout object is returned One wouldn't want to 'append' to a stream.... is it because binary mode can still be turned on and off this way
subprocess.popen question   (126 Views)
I am trying to modify a programming example and I am coming up with two problems... first is that I can't seem to pass along the arguments to the external command (I have been able to do that with the old module and cmd is the command I wish to try) all the output seems to be returned as one line (at least when I run the program in spe). import subprocess from os import system cmd = """gawk -f altertime.awk -v time_offset=4 -v outfile="testdat.sco" "i1.sco" """ #subprocess.Popen. last_line = subprocess.Popen(['gawk.exe'], stdout=subprocess.PIPE).communicate()[0] xx = 0 for line in last_line: xx = xx + 1 if xx < 2: print line print str(xx)
poplib.retr doens't flag message as read   (121 Views)
, I am trying to use the poplib library to get emails using the retr method. The small program bellow works but the message aren't flagged as read which puzzles me. I believe the pop server is qmail 1.0.6 / vpopmail 5.2.1 and I am running the following script on Windows using Pyhton 2.5. import poplib import email pop = poplib.POP3('mail.server.com') pop.user('email@server.com') pop.pass_('password') status, msg_list, octets = pop.list() for msg_number in [msg.split(' ')[0] for msg in msg_list]: status, lines, octets = pop.retr(msg_number) msg = email.message_from_string('\n'.join(lines)) if not msg.is_multipart() and msg.get_content_type() == 'text/plain': print msg.get('Subject') print msg.get_payload() pop.quit() Why aren't the message flagged as read Is there a way to manually mark them read
popen5: New POSIX process module   (117 Views)
I've written a new popen-like module for Python. This module overcomes several limitations with the old popen2 module, but also aims to be a generic module for starting and communicating with processes on POSIX systems. It can replace several older modules and functions, like: os.system os.spawn* os.popen* popen2.* commands.* This module features: * Cross-process exceptions: Exceptions happening in the child before the new process has started to execute are re-raised in the parent. This means that it's easy to handle exec() failures, for example. With popen2, it's impossible to detect if the execution failed. * A hook for executing customized code between fork and exec. This can be used for, for example, changing uid. * No implicit call of /bin/sh. This means that there is no need for escaping dangerous shell meta characters. * A communicate() method, which makes it easy to send stdin data and read stdout and stderr data, without risking deadlocks. * Support for connecting several subprocesses (shell "pipe"). The module is available from http://cvs.lysator.liu.se/viewcvs/vi...=python-popen5, or via anonymous CVS (server:anonymous@cvs.lysator.liu.se:/cvsroot/python-popen5). feedback is appreciated. /Peter strand
POP3 - Using poplib only shows the first few hundred messages in themailbox   (267 Views)
, I am trying to use POP3_SSL class of the poplib module to read email from my gmail account. I can connect just fine using the example here http://www.python.org/doc/lib/pop3-example.html import getpass, poplib M = poplib.POP3('localhost') M.user(getpass.getuser()) M.pass_(getpass.getpass()) numMessages = len(M.list()[1]) for i in range(numMessages): for j in M.retr(i+1)[1]: print j That is the above sample code from the python doc. While everything works fine, the problem is that when I use the list() function it only returns about 400 messages starting from the beginning of my inbox. I have probably 10,000 emails in my gmail account. I don't see any pop3 object functions to "move" around the inbox or anything of the like. Could someone point me in the right direction I'm sure there must be something simple I am missing.

popen hangs sporadically   (130 Views)
I have a script that calls the function write_tmpfile, which looks something like this: def write_tmpfile(f, tmpfile): # set-up code omitted in_f = popen("""grep -v '^\\[eof\\]$' %s |\ grep '[^[:space:]]' |\ sort -u""" % f) out_f = open(tmpfile, 'w') try: while 1: line = in_f.readline() if not line: break # i omit the code that munges line out_f.write(line) finally: in_f.close() out_f.close() The script calls this function several thousand times. (The average size of the input file f is 70K lines (0.5MB); the maximum size is about 35M lines, or 200MB.) This function works perfectly most of the time, but it deadlocks sporadically. (And it's a deadlock! The script can be stuck for hours, until I kill it.) I can't say for sure where the deadlock is happening (and I'd appreciate suggestions on how to pinpoint this), but I *think* it is at the in_f.readline() statement. So maybe the problem is with the pipe. (But FWIW, I've used exactly the same pipe in another script that processes the same set of files (but does not write a temporary file when it does this), and this script terminates without any problem. I.e. the input files are not too large for the pipe.) I suppose that I could use some timeout mechanism to unwedge the script when it deadlocks and then repeat the call to write_tmpfile, but I'd prefer to avoid the deadlock in the first place. I'd appreciate suggestions on how to troubleshoot and debug this thing. TIA! Kynn -- NOTE: In my address everything before the first period is backwards; and the last period, and everything after it, should be discarded.
Using poplib to parse headers   (113 Views)
, I am writing a Python program to check email using POP3. I've tried the sample code from python.org, and it works great. In other words, the code below successfully prints out my emails. import getpass, poplib, email M = poplib.POP3('mail.blah.com') M.user('username') M.pass_('password') numMessages = len(M.list()[1]) for i in range(numMessages): for j in M.retr(i+1)[1]: print j M.quit() However, if I understand right, the Python poplib library will also parse the email for me so that I can iterate through the headers, body, etc, of each message, and use them in my program. I think the method I need to use is email.message_from_file, but I'm having difficulty getting it to work. Can anyone explain me how I would extend the above example to do this I tried to do this by using in the i loop the line: message = email.message_from_file(j) but I get the error: "AttributeError: 'str' object has no attribute 'readline'" Please forgive this very basic question. I do most of my programming in PHP and I'm just getting started with Python. Many
poplib - retr() getting stuck   (212 Views)
I am using poplib's retr() to fetch mails from my gmail account. It works fine, in some cases it gets stuck inside the retr() method and does not come out. From the logs I could find that when retr() is called, it stops executing further statements, nor does it throw an exceptions but simply stops. My code is roughly like the foll: try: print "1" mymsg = M.retr(msg_no) print "2" except poplib.error_proto, e: print "exception1" except Exception, e: print "exception2" What can be the reason for this Can anyone help me.
