Named counting-semaphore resources — the Dep::Resource side of the v2 model. A ResourceTable tracks per-name capacity + held counts; unconfigured names default to capacity 1 (created lazily). try_acquire_all grants every requested unit or none, leaving the table untouched on failure — so a node never holds one resource while waiting for another, which is what makes the scheduler deadlock-free without cycle detection. Duplicate names in a request are summed; over-capacity requests can never acquire. release_all saturates rather than underflowing. Runtime scheduler state, not persisted: held counts are rederived from running nodes on restart. Guard objects (RAII release, recursive re-entrancy) wrap this in a follow-up. |
