Data-Pool-Shared-0.08

Changes for version 0.08 - 2026-07-22

  • Fix a use-after-free in set() for the Raw and Str pools: the value argument is a bare SV, so its overload or tie magic runs Perl that can destroy the pool, after which the already-captured handle was still used. Such a call now croaks.
  • Reject a crafted header whose full layout overflows 64 bits. The attach-time check counted only the header, while the create paths counted header + bitmap + owners + data, so a wrapped total_size could place the slot pointers outside the mapping.
  • Give Data::Pool::Shared::Guard a $VERSION so PAUSE indexes it.
  • Reject alloc_n counts above 2^32.
  • A guard no longer frees the parent slot from a forked child.
