extend peers/library/transfer list filters - Extend CLI commands with health, reputation, search-task, transfer cancel, cache clear; add --priority, --status/--limit, --artist/--title/--album/--genre - Refactor monolithic main.rs (~2000 lines) into commands.rs + formatters.rs - Make demo_output.rs use real formatter implementations to avoid drift - Unify KV output format (all via println + join);

wait_for signature improved to accept async closures with Duration-based timeout - three_nodes.rs: DHT propagation sleeps replaced with polling loops that wait until providers/records are actually discovered - concurrent_stress.rs: DHT and search sleeps replaced with polling loops using tokio::time::timeout - transfer.rs tests: wait_for_terminal_task uses timeout-based polling - control.rs tests: search completion polling uses timeout - p2p.rs tests: remove unnecessary startup sleep; known-peer polling uses timeout-based loop - network.rs tests: DHT propagation sleep replaced with polling loop - audit.rs tests: increase pipeline setup wait to 100ms for stability Refs: TEST_PLAN.md Phase 2, TEST-INFRA-1, TEST-INFRA-4 --- crates/wemusic-daemon-core/src/audit.rs | 3 +- crates/wemusic-daemon-core/src/control.rs | 21 +++++--- crates/wemusic-daemon-core/src/p2p.rs | 6 +-- crates/wemusic-daemon-core/src/transfer.rs | 5 +- .../tests/concurrent_stress.rs | 50 ++++++++++++------ .../tests/three_nodes.rs | 51 ++++++++++++------- crates/wemusic-protocol/src/network.rs | 13 +++-- crates/wemusic-test-utils/src/lib.rs | 29 +++++++---- 8 files changed, 117 insertions(+), 61 deletions(-) diff --git a/crates/wemusic-daemon-core/src/audit.rs b/crates/wemusic-daemon-core/src/audit.rs index 26c574e..546cf01 100644 --- a/crates/wemusic-daemon-core/src/audit.rs +++ b/crates/wemusic-daemon-core/src/audit.rs @@ -1036,7 +1036,8 @@ mod tests { ..Default::default() }) .unwrap();
