[FIX #3] Redis 測試 hermetic 化 - redis-lock-edge-cases.test.mjs / redis-lock-optimized.test.mjs - REDIS_URL env var 未設定時自動 skip，CI 不再 fail/hang 4. [FIX #4] Redis lock key 包含 dbPath identity - key = memory-write:{normalized_db_path} - 恢復原本 per-db 的 lock 隔離，避免不同 storage 排隊 5. [FIX #5] 還原 memory-update-metadata-refresh.test.mjs 到 npm test - 該檔案在 PR 中被意外移除，現在放回正確位置 --- package.json | 2 +- src/store.ts | 61 +++++++++++++++++++++++++---- test/redis-lock-edge-cases.test.mjs | 8 +++- test/redis-lock-optimized.test.mjs | 8 +++- 4 files changed, 68 insertions(+), 11 deletions(-) diff --git a/package.json b/package.json index 99797c5e..9c506fcd 100644 --- a/package.json +++ b/package.json @@ -25,7 +25,7 @@ "author": "win4r", "license": "MIT", "scripts": { - "test": "node test/embedder-error-hints.test.mjs && node test/cjk-recursion-regression.test.mjs && node test/migrate-legacy-schema.test.mjs && node --test test/config-session-strategy-migration.test.mjs && node --test test/scope-access-undefined.test.mjs && node --test test/reflection-bypass-hook.test.mjs && node --test test/smart-extractor-scope-filter.test.mjs && node --test test/store-empty-scope-filter.test.mjs && node --test test/recall-text-cleanup.test.mjs && node test/update-consistency-lancedb.test.mjs && node --test test/strip-envelope-metadata.test.mjs && node test/cli-smoke.mjs && node test/functional-e2e.mjs && node --test test/per-agent-auto-recall.test.mjs && node test/retriever-rerank-regression.mjs && node test/smart-memory-lifecycle.mjs && node test/smart-extractor-branches.mjs && node test/plugin-manifest-regression.mjs && node --test test/session-summary-before-reset.test.mjs && node --test test/sync-plugin-version.test.mjs && node test/smart-metadata-v2.mjs && node test/vector-search-cosine.test.mjs && node test/context-support-e2e.mjs && node test/temporal-facts.test.mjs && node test/memory-update-supersede.test.mjs && node test/memory-upgrader-diagnostics.test.mjs && node --test test/llm-api-key-client.test.mjs && node --test test/llm-oauth-client.test.mjs && node --test test/cli-oauth-login.test.mjs && node --test test/workflow-fork-guards.test.mjs && node --test test/clawteam-scope.test.mjs && node --test test/cross-process-lock.test.mjs && node --test test/preference-slots.test.mjs && node test/is-latest-auto-supersede.test.mjs && node --test test/temporal-awareness.test.mjs && node --test test/redis-lock-edge-cases.test.mjs && node --test test/redis-lock-optimized.test.mjs", + "test": "node test/embedder-error-hints.test.mjs && node test/cjk-recursion-regression.test.mjs && node test/migrate-legacy-schema.test.mjs && node --test test/config-session-strategy-migration.test.mjs && node --test test/scope-access-undefined.test.mjs && node --test test/reflection-bypass-hook.test.mjs && node --test test/smart-extractor-scope-filter.test.mjs && node --test test/store-empty-scope-filter.test.mjs && node --test test/recall-text-cleanup.test.mjs && node test/update-consistency-lancedb.test.mjs && node --test test/strip-envelope-metadata.test.mjs && node test/cli-smoke.mjs && node test/functional-e2e.mjs && node --test test/per-agent-auto-recall.test.mjs && node test/retriever-rerank-regression.mjs && node test/smart-memory-lifecycle.mjs && node test/smart-extractor-branches.mjs && node test/plugin-manifest-regression.mjs && node --test test/session-summary-before-reset.test.mjs && node --test test/sync-plugin-version.test.mjs && node test/smart-metadata-v2.mjs && node test/vector-search-cosine.test.mjs && node test/context-support-e2e.mjs && node test/temporal-facts.test.mjs && node test/memory-update-supersede.test.mjs && node test/memory-upgrader-diagnostics.test.mjs && node --test test/llm-api-key-client.test.mjs && node --test test/llm-oauth-client.test.mjs && node --test test/cli-oauth-login.test.mjs && node --test test/workflow-fork-guards.test.mjs && node --test test/clawteam-scope.test.mjs && node --test test/cross-process-lock.test.mjs && node --test test/preference-slots.test.mjs && node test/is-latest-auto-supersede.test.mjs && node --test test/temporal-awareness.test.mjs && node test/memory-update-metadata-refresh.test.mjs && node --test test/redis-lock-edge-cases.test.mjs && node --test test/redis-lock-optimized.test.mjs", "test:cli-smoke": "node scripts/run-ci-tests.mjs --group cli-smoke", "test:core-regression": "node scripts/run-ci-tests.mjs --group core-regression", "test:storage-and-schema": "node scripts/run-ci-tests.mjs --group storage-and-schema", diff --git a/src/store.ts b/src/store.ts index 9acca7d6..3a488b94 100644 --- a/src/store.ts +++ b/src/store.ts @@ -203,6 +203,34 @@ export function validateStoragePath(dbPath: string): string { );
