This saves one allocation per-attr, per-message. When running imap.fetch(1..-1, 'UID') on a mailbox with 30000 messages; this saves 30000 allocations. This relies on the String#-@ change in [Feature #13077] * net/imap: use frozen, deduplicated string in attr name (key) Trivial (1-byte change :), I may commit in a few days if no response. ---Files-------------------------------- 0001-net-imap-dedupe-attr-keys-in-Net-IMAP-FetchData.patch (1 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
