Category: Library (Lib) Group: Python 2.5 Status: Open >Resolution: Accepted Priority: 6 Private: No Submitted By: David Watson (baikie) Assigned to: A.M. Kuchling (akuchling) Summary: mailbox (Maildir): avoid losing messages on name clash Initial Comment: The Maildir specification says that messages should be moved into the "new" directory using link()/unlink(), not rename(). This isn't for compatibility with ancient Unixes, but to avoid overwriting an existing message if the "unique" name turns out not to be unique after all. (In the current implementation this can happen if the system clock only has whole-second resolution and deliveries are being done in subprocesses, or the clock has been adjusted backwards, or two machines have the same hostname.) Similarly, the file in "tmp" should be created O_EXCL. This patch implements these requirements, falling back to rename() if link() is unavailable (where on Windows at least, it's supposed to fail if the destination exists), and raising ExternalClashError when the link/rename fails due to the name already being taken in "new". ---------------------------------------------------------------------- >Comment By: A.M.
