If the problem is AV scanners, then they should be opening them properly for this (and since the delete is not failing but is being deferred, I assume it's allowing deletes). If the problem is elsewhere in our code base then we have a different bug.

One additional thing that may help (if support.unlink doesn't already do it) is to rename the file before deleting it. Renames are always possible even with open handles, and then you can create a new file at the original name.
Renaming open files typically fails with a sharing violation (32). Most programs open files with read and write sharing but not delete sharing. This applies to Python, except temporary files (i.e. os.O_TEMPORARY) do share delete access. Renaming a file is effectively adding a new link and deleting the old link, so it requires opening the file with delete access. Also, renaming a directory that has open files in the tree fails with access denied (5). _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/steve.dower%40python.org
