Release Aether 0.467.0 · aether-lang-dev/aether

What's new in 0.467.0

A caught panic leaked every allocation made since the try (#1301).
longjmp skipped the deferred scope-exit frees, so guarded blocks (and
every scheduler-wrapped actor step) leaked whatever they had allocated
before panicking. A thread-local allocation journal now mirrors the armed
deferred frees one-for-one: generated code journals a tracked local when
its flag is armed, the single free choke point forgets on every normal
free, ownership handoffs (return, container/actor/message adoption)
forget at the transfer, and aether_panic() drains the innermost frame's
still-live entries before the jump, freeing exactly the frees the jump
would have skipped. Escaped values are never journaled, so the drain is a
leak-fix by construction, never a use-after-free. Nested try drains
stay frame-local; a panicking actor's step-scoped allocations are
reclaimed before the actor is marked dead; the no-panic hot path shows no
measurable cost on the ping-pong benchmark. Verified 405 leaks to 0 on
the issue's alloc-then-panic matrix. Regressions:
tests/regression/test_panic_unwind_cleanup.ae,
tests/integration/panic_unwind_no_leak/ (50000 caught panics, RSS
flat), tests/integration/panic_actor_step_drain/.

fs.mounts() and fs.block_info(dev) (#1118). Mount enumeration
with per-entry source/point/fstype/options accessors: Linux
/proc/self/mountinfo (octal escapes decoded), macOS and the BSDs
getmntinfo(3), Windows drive letters. Block-device size/removable/
transport via the Linux sysfs backend (partitions resolve the removable
flag through their parent disk); other platforms report unsupported
through the error slot rather than fabricating an answer. Regression:
tests/regression/test_std_fs_mounts.ae.
