From c0caf43af91a8178ebb518243c71e5c4aba65eaf Mon Sep 17 00:00:00 2001 From: perhaps <2025680871@qq.com> Date: Sun, 26 Jul 2026 16:37:00 +0800 Subject: [PATCH 1/4] feat: add session replay consistency framework MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a backend-agnostic replay harness that runs a fixed set of fixture cases against InMemory and a configurable backend (SQLite by default, Redis or MySQL via env var), then diffs the canonical snapshots so silent divergences between backends surface as test failures. - trpc_agent_sdk/replay: harness + diff engine + multiple backends - tests/sessions: replay fixtures, integration tests for Redis and SQL - .github/workflows: replay-integration CI (Redis + MySQL jobs) - docs/mkdocs: en + zh design docs - pyproject.toml: register 'integration' marker - examples/replay_consistency_demo: end-to-end demo - tests/sessions/replay_cases: replay case fixtures (jsonl) - tests/sessions/replay_diff_report.json: latest replay snapshot ci: replay-integration workflow skip semantics The integration jobs (Redis, MySQL) deliberately do NOT use a job-level ``if:`` condition. ``secrets.X`` is intentionally unavailable in job-level ``if:`` expressions for security reasons, and ``env.X`` is resolved in declaration order — both trip the GitHub Actions expression linter. The "skip cleanly when the operator has not configured the integration secret" behaviour is implemented one layer down, in the ``integration_runtime`` fixture in tests/sessions/conftest.py: every Redis/MySQL integration test reads the fixture and calls ``pytest.skip(...)`` when the env var is unset. Pytest's skip is a clean exit code 0, so the workflow stays green for forks that opt out of running external services — exactly as the header comment promises.
