Dropping the lookup stopwatch also dropped what it checked: a gated peer now proves lookup returns from the owner while a slow peer still holds, with the probe timeout raised past the guard so a serial lookup fails. --- sandboxd/pool/claims_test.go | 5 +++-- sdk/python/tests/test_fault_matrix.py | 27 +++++++++++++++++++++++++++ 2 files changed, 30 insertions(+), 2 deletions(-) diff --git a/sandboxd/pool/claims_test.go b/sandboxd/pool/claims_test.go index 8bcba06dc..6650d485e 100644 --- a/sandboxd/pool/claims_test.go +++ b/sandboxd/pool/claims_test.go @@ -27,14 +27,15 @@ func TestRecommitKeepsOneRetrierWhileWritesFail(t *testing.T) { dir := filepath.Join(t.TempDir(), "absent") m.store.path = filepath.Join(dir, "claims.json") + before := recommitGoroutines(t) for range 50 { m.mu.Lock() snap := m.store.set(sb) m.mu.Unlock() m.store.recommit(t.Context(), snap) } - if n := recommitGoroutines(t); n != 1 { - t.Fatalf("%d retriers for 50 failed persists, want one", n) + if n := recommitGoroutines(t) - before; n > 1 || !m.store.recommitting.Load() { + t.Fatalf("%d new retriers for 50 failed persists, want one", n) } if err := os.MkdirAll(dir, 0o750); err != nil { diff --git a/sdk/python/tests/test_fault_matrix.py b/sdk/python/tests/test_fault_matrix.py index 15ec6cf1e..e7c400dbd 100644 --- a/sdk/python/tests/test_fault_matrix.py +++ b/sdk/python/tests/test_fault_matrix.py @@ -3,9 +3,12 @@ import errno import http.client import socket +import threading +import cocoonsandbox.client import pytest from cocoonsandbox import APIError, Client +from conftest import bounded ENTRY_POINTS = pytest.mark.parametrize( ("path", "claim"), @@ -183,6 +186,30 @@ def test_lookup_resolves_past_an_unreachable_peer(spawn_node, request, peer): assert sb.owner == "10.0.0.9:7777" +def test_lookup_returns_the_first_owner_without_waiting_for_a_slow_peer(spawn_node, monkeypatch): + monkeypatch.setattr(cocoonsandbox.client, "_PEERS_TIMEOUT", 60.0) + gate = threading.Event() + + def slow(body, path): + gate.wait(60) + return 404, {"error": "not here"} + + slow_peer = spawn_node({("GET", "/v1/sandboxes/sb_1/owner"): slow}) + owner = spawn_node({("GET", "/v1/sandboxes/sb_1/owner"): lambda body, path: (200, {"owner_addr": "10.0.0.9:7777"})}) + entry = spawn_node( + { + ("GET", "/v1/sandboxes/sb_1/owner"): lambda body, path: (404, {"error": "not here"}), + ("GET", "/v1/peers"): lambda body, path: (200, {"peers": [slow_peer, owner]}), + } + ) + try: + sb = bounded(lambda: Client(entry, timeout=60.0).lookup("sb_1", "tok")) + assert not gate.is_set() + finally: + gate.set() + assert sb.owner == "10.0.0.9:7777" + + def test_lookup_all_miss(spawn_node, dead_addr): entry = spawn_node( {
