New submission from Serhiy Storchaka:
If ElementTree.iterparse() is called with file names, it opens a file. When
resulting iterator is not exhausted, the file lefts not closed.
>>> import xml.etree.ElementTree as ET
>>> import gc
>>> ET.iterparse('/dev/null')
<xml.etree.ElementTree._IterParseIterator object at 0xb6f9e38c>
>>> gc.collect()
__main__:1: ResourceWarning: unclosed file <_io.BufferedReader name='/dev/null'>
34
Martin Panter proposed in issue25688 to add an explicit way to clean it up,
like a generator.close() method.
