In mori: Shared Memory for R Objects

mori 0.2.2

• Region name counters now start at a per-process random value, so a process reusing a crashed process's PID no longer collides with its orphaned regions (#50).

mori 0.2.1

• New prune_shared() removes shared memory regions orphaned by a process that was killed before it could clean up (#25).
• When share() fails to create a shared memory region it now reports the requested size and, where applicable, an actionable hint (e.g. raising a container's /dev/shm limit) instead of a generic message (#29).

mori 0.2.0

• Wire-format change (breaking): The serialization format and the shared memory region naming scheme have both changed.
• shared_name() and map_shared() now round-trip for sub-lists and extracted elements, not just whole shared objects. Sub-object identifiers carry a bracketed index path (e.g. /mori_abc_1[2,3]).
• shared_name() now returns NULL for non-shared inputs (previously the empty string ""); shared_name(x) %||% "" retains the previous behaviour.
• share() on Linux fails with a clean R error when /dev/shm is too small (typical in containers, where the limit can be raised at start) instead of SIGBUS-ing mid-serialize (#14).
• map_shared() on Linux no longer prefaults the whole region, restoring lazy first-touch access to match macOS.

mori 0.1.0

• Initial CRAN release.
