1. [New issue] Unclosed file handles after execution of ZipFile.extractall method
http://ironpython.codeplex.com/workitem/33571
User constantineiv has proposed the issue:

"After extracting some zip archive by zipfile.ZipFile.extractall method there are sometimes unclosed handles to archive file (after execution under context manager or after explict archive closing by close method). These open handles prevent later deletion of archive zip file.

This issue manifested only in IronPython, never noticed in CPython.

Please consider following code run in IPy 2.7.3 and Win7 (also tested in IPy 2.7.1 and Win2003):

--------------------------------------------
import zipfile
import subprocess

archive_path = r'c:\dir\archive.zip'
unpack_path = r'c:\dir\unpacked'
handle_tool_path = r'c:\dir\handle.exe'

def print_archive_handles(archive_path):
    p = subprocess.Popen([handle_tool_path, archive_path],
                         stdout=subprocess.PIPE,
                         stderr=subprocess.STDOUT)
    stdout, stderr = p.communicate()
    print stdout

with zipfile.ZipFile(archive_path) as z:
    z.extractall(unpack_path)

print_archive_handles(archive_path)
--------------------------------------------

Print output is:

Handle v3.46

ipy.exe            pid: 7944   type: File           620: C:\dir\archive.zip



As seen in above output of handle.exe tool (downloadable from http://technet.microsoft.com/en-US/sysinternals), there is an open handle to archive file even after an archive is closed in context manager."
