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."
