I wanted to show an image uploader (using Zend_Form_Element_File) but when the user was editing the image (replacing it) it showed the current image in the form. For some reason ZF devs won’t let you change the view helper for a Zend_Form_Element_File, so subclassing it and changing the view helper don’t work. There is a […]
Continue ReadingTags: Python, memory leak, leek, object, garbage collection, garbage collector, __del__, inspect, gc, DEBUG_LEAK I have a nasty memory leak in my Python script which I can’t find.

The os module […]

Here is a little example that downloads the msn.com web page, parses it using BS and grabs all the LINK tags that are linking to a CSS file: from BeautifulSoup import BeautifulSoup import urllib2url = “http://www.msn.com” request = urllib2.Request(url) […]

Continue ReadingThis post is about Zend Framework, sql error reporting. Problem: If your SQL has an error in it, Zend Framework throws a Zend_Db_Statement_Mysqli_Exception, the default exception message is pretty pants and does not show the whole SQL query (it only shows the first 10 characters or so!) Lets fix it so it shows the whole query. I found […]
