[PATCH v2 0/1] git-p4: auto-delete named temporary file

From: Philip McGraw via GitGitGadget <gitgitgadget@gmail.com>
Date: Aug 2, 2019, 19:43 UTC
Message-ID: <pull.303.v2.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.303.git.gitgitgadget@gmail.com>

Take new approach using the NamedTemporaryFile() file-like object as input to the ZipFile() which auto-deletes after implicit close leaving with scope.

Original code produced double-open problems on Windows platform from using already open NamedTemporaryFile() generated filename instead of object.

Thanks to Andrey for patiently suggesting several iterations on this change for avoiding exceptions!

Also print error details after resulting IOError to make debugging cause of exception less mysterious when it has nothing to do with "git version recent enough."
