New reusable pending-execution coordinator with fail-closed command matching: - Store/TakeCatchUp/TakeRebuild/Cancel/Has/Peek - TakeCatchUp: fail-closed on target LSN mismatch (cancel + return nil) - TakeRebuild: same fail-closed semantics - Cancel callback invoked on mismatch or explicit cancellation 9 tests prove boundary behavior: - match succeeds, mismatch cancels, explicit cancel, noop on empty, peek non-destructive, store replaces, take from empty No weed/ imports. Pure coordination logic reusable by any adapter shell. weed/server/block_recovery.go rebinding deferred to Task I. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
sw-block
Private WAL V2 and standalone block-service workspace.
Purpose:
- keep WAL V2 design/prototype work isolated from WAL V1 production code in
weed/storage/blockvol - allow private design notes and experiments to evolve without polluting V1 delivery paths
- keep the future standalone
sw-blockproduct structure clean enough to split into a separate repo later if needed
Suggested layout:
design/: shared V2 design docsprototype/: code prototypes and experiments.private/: private notes, phase development, roadmap, and non-public working material
Repository direction:
- current state:
sw-block/is an isolated workspace insideseaweedfs - likely future state:
sw-blockbecomes a standalone sibling repo/product - design and prototype structure should therefore stay product-oriented and not depend on SeaweedFS-specific paths
