New submission from Giuseppe Attardi :
I confirm the presence of a serious memory leak in ElementTree, using the
iterparse() function.
Memory grows disproportionately to dozens of GB when parsing a large XML file.
For further information, see discussion in:
http://www.gossamer-threads.com/lists/python/bugs/912164?do=post_view_threaded#912164
but notice that the comments attributing the problem to the OS are quite off
the mark.
To replicate the problem, try this on a Wikipedia dump:
iterparse = ElementTree.iterparse(file)
id = None
for event, elem in iterparse:
if elem.tag.endswith("title"):
title = elem.text
elif elem.tag.endswith("id") and not id:
id = elem.text
elif elem.tag.endswith("text"):
print id, title, elem.text[:20]
