RE: Terminate a python script from linux shell / bash script
by Gros Bedo July 31, 2008

July 31, 2008

Thank you guys for your help. My problem is that I project to use this command to terminate a script when uninstalling the software, so I can't store the PID. This command will be integrated in the spec file of the RPM package. Here's the script I'll use, it may help someone else: #!/bin/sh # PYTHON SCRIPT PROCESS KILLER by GBO v0.1 # This script will look for all the lines containing $SOFTWARENAME in the process list, and close them SOFTWARENAME='yoursoftware' #This is case insensitive JOBPRESENT=$(ps -ef | grep -i $SOFTWARENAME | grep -v grep) echo $JOBPRESENT ps -ef | grep -i $SOFTWARENAME | grep -v grep | awk '{print $2}' | xargs kill _________________________________________________________________ Pendant tout l'été, consultez vos emails Hotmail sur votre mobile ! http://www.messengersurvotremobile.com/?d=hotmail

ANN: Google custom search engine for Python
by Gerard flanagan July 31, 2008

July 31, 2008

What is it? ----------- A Google custom search engine which targets only the following sites: + `The Hazel Tree <http://thehazeltree.org>`__ + `The Python standard library docs <http://docs.python.org/lib>`__ + `The Python wiki <http://wiki.python.org>`__ + `Python Package Index <http://pypi.python.org/pypi>`__ Where can I access it? ---------------------- The home page of the search engine is here: http://www.google.com/coop/cse?cx=002031040340806163079:nkigkp_irqk As well as accessing it from its home page, you can link to it from your own web sites, or add it as a gadget to your Google home page (if you have one) - see the above link for details. No ads ------ `The Hazel Tree <http://thehazeltree.org>`__ is a not-for-profit site and no ads will appear in the search results. Using refinements ----------------- To refine the search to any of the individual sites, you can specify a refinement using the following labels: stdlib, wiki, pypi, thehazeltree So, to just search the python wiki, you would do: somesearchterm more:wiki and similarly: somesearchterm more:stdlib somesearchterm more:pypi somesearchterm more:thehazeltree About http://thehazeltree.org ----------------------------- `The Hazel Tree <http://thehazeltree.org/>`__ is a collection of popular Python texts that I have converted to reStructuredText and put together using `Sphinx <http://sphinx.pocoo.org>`__. It's in a publishable state, but not as polished as I'd like, and since I'll be mostly offline for the next month it will have to remain as it is for the present. However, the search engine is ready now and the clock is ticking on its subscription (one year, renewal depending on success of site), so if it's useful to anyone, it's all yours (and a link back to http://thehazeltree.org would be appreciated). Cheers, G.

Is it possible to consume UTF8 XML documents using xml.dom.pulldom?
by Simon Willison July 31, 2008

July 31, 2008

I'm having a horrible time trying to get xml.dom.pulldom to consume a UTF8 encoded XML file. Here's what I've tried so far: >>> xml_utf8 = """<?xml version="1.0" encoding="UTF-8" ?> <msg>Simon\xe2\x80\x99s XML nightmare</msg> """ >>> from xml.dom import pulldom >>> parser = pulldom.parseString(xml_utf8) >>> parser.next() ('START_DOCUMENT', <xml.dom.minidom.Document instance at 0x6f06c0>) >>> parser.next() ('START_ELEMENT', <DOM Element: msg at 0x6f0710>) >>> parser.next() ... UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 21: ordinal not in range(128) xml.dom.minidom can handle the string just fine: >>> from xml.dom import minidom >>> dom = minidom.parseString(xml_utf8) >>> dom.toxml() u'<?xml version="1.0" ?><msg>Simon\u2019s XML nightmare</msg>' If I pass a unicode string to pulldom instead of a utf8 encoded bytestring it still breaks: >>> xml_unicode = u'<?xml version="1.0" ?><msg>Simon\u2019s XML nightmare</msg>' >>> parser = pulldom.parseString(xml_unicode) ... /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ xml/dom/pulldom.py in parseString(string, parser) 346 347 bufsize = len(string) --> 348 buf = StringIO(string) 349 if not parser: 350 parser = xml.sax.make_parser() UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 32: ordinal not in range(128) Is it possible to consume utf8 or unicode using xml.dom.pulldom or should I try something else? Thanks, Simon Willison

Optimizing size of very large dictionaries
by python＠bdurham.com July 31, 2008

July 31, 2008

Are there any techniques I can use to strip a dictionary data structure down to the smallest memory overhead possible? I'm working on a project where my available RAM is limited to 2G and I would like to use very large dictionaries vs. a traditional database. Background: I'm trying to identify duplicate records in very large text based transaction logs. I'm detecting duplicate records by creating a SHA1 checksum of each record and using this checksum as a dictionary key. This works great except for several files whose size is such that their associated checksum dictionaries are too big for my workstation's 2G of RAM. Thank you, Malcolm

You are confusing languages with implementations, as I pointed out earlier. Java is a language. I have used at least 2 Java compilers, ie they compiled Java source to native machine language.

Possible to have multiple loop variables?
by laredotornado July 31, 2008

July 31, 2008

I don't know why I thought this would work, but I would like to have 3 variables in my for loop per iteration. Those familiar will know that this ms1 = {'managed1':7019:8020,'managed2':7020:8021} for m, lp, ssl_lp in ms1.items(): managedServer = create(m,'Server') print 'creating managed server '+m managedServer.setListenAddress('147.191.71.70') managedServer.setListenPort(lp) managedServer.setEnabled(0) cd('SSL/cgServer') managedServer.setEnabled(1) managedServer.setListenPort(ssl_lp) managedServer.setCluster(clus1) causes File "/export/third-party/etsbea/home/etsbea/tests/wlst/ createcluster.py", line 9 ms1 = {'managed1':7019:8020,'managed2':7020:8021} ^ SyntaxError: invalid syntax How would I set up the ms1 array such that I can use three items per object? Thanks, - Dave
