Data-HashMap-0.09

Changes for version 0.09 - 2026-09-11

  • Per-process hash seed; key order and freeze output vary between runs
  • SV* variants: opt-in value copying (fourth new() argument)
  • Maps are not cloned into new threads; maps made in a thread work
  • Storable support for non-SV* variants; SV* variants croak
  • new() croaks on refs, non-numbers and extra arguments
  • ttl below one second rounds up to one
  • Out-of-range integers croak instead of wrapping
  • Downgradable UTF-8 keys equal their Latin-1 form
  • keys, values and items return a count in scalar context
  • Every variant isa Data::HashMap
  • TTL maps stay bounded; lru_skip below 50 takes effect
  • Fix crashes: tied from_hash, destroyed-map merge, re-entrant DESTROY
  • Fix clone losing keys, pop/shift missing entries, put_ttl leak
  • Fix severe LRU and sparse-table slowdowns
  • thaw, from_hash and merge fail cleanly on bad input or low memory
  • POD: caveats section, a page per variant
