Stackpulse 0.3.0 makes perf attachment transactional, generation-safe, and more faithful to Linux perf while reducing duplicated lifecycle state.

Fixed

  • Output rings retain a live poll anchor after their original owner exits.
  • Ring sizing uses the runtime page size.
  • Stop/resume failures and rollback errors are propagated without losing raw errno.
  • Hardware, kernel, and inheritance fallbacks are limited to the exact syscall errors they can recover from.
  • Reattaching the same process generation is idempotent, and process snapshots reject PID-reuse races.
  • Thread-directory errors are propagated instead of producing partial snapshots.

Changed

  • ELF parse errors preserve the affected path and original parser source chain.
  • Perf event and output-ring state use one canonical representation per role.
  • Duplicated Python-runtime predicates and stale live-recording benchmark helpers were removed.
