Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Ritesh Raj Sarraf (riteshsarraf) Assigned to: Nobody/Anonymous (nobody) Summary: zipfile "append" mode should create a file if not present Initial Comment: The line filename = zipfile.ZipFile(zip_file_name, "a") throws an exception if the given filename is not present already. Shouldn't it create a file (in case one is not there) since it is "append" mode ?? It's throwing an OSError Exception stating "No such file/directory". Normal convention has been that when opening a file in append mode, if the file is not present a new file is created. Why is this non-standard? ---------------------------------------------------------------------- >Comment By: Gregory P. Smith (greg) Date: 2006-07-08 10:38 Message: Logged In: YES user_id=413 I agree. append semantics generally mean append or create. +1 from me on fixing this bug. if any existing code is depending on the side effect from opening a zip file in 'a' mode to tell them that it doesn't already exist this change would break that; but I'd argue that such code is already broken and should be cleaned up. ---------------------------------------------------------------------- Comment By: Thomas Lee (krumms) Date: 2006-07-05 19:31 Message: Logged In: YES user_id=315535 Patch #1517891 resolves this.
