New submission from Stephen Gildea <stepheng-...@gildea.com>:
A message's flags are stored in its filename by Maildir, so the flags are available without reading the message file itself. The structured message file name makes it efficient to scan a large mailbox to select only messages that are, for example, not Trashed. The mailbox.Maildir interface does not expose these flags, however. The only way to access the flags through the mailbox library is to create a mailbox.MaildirMessage object, which has a get_flags() method. But creating a MaildirMessage requires opening the message file, which is slow. I propose adding a parallel get_flags(key) method to mailbox.Maildir, so that the flags are available without having to create a MaildirMessage object. In iterating through a mailbox with thousands of messages, I find that this proposed Maildir.get_flags() method is 50 times faster than MaildirMessage.get_flags(). ---------- components: Library (Lib) messages: 413145 nosy: gildea priority: normal severity: normal status: open title: Add Maildir.get_flags() to access message flags without opening the file type: enhancement versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46734> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
