fix(langgraph-dev): rotate langgraph_dev.log when it exceeds 50MB (#270)
* fix(langgraph-dev): rotate langgraph_dev.log when it exceeds 50MB ``_LOG_FILE`` (``~/.config/evoscientist/langgraph_dev.log``) was opened in ``start_langgraph_dev`` with plain ``"ab"`` and never rotated, so it grew unbounded over weeks/months of heavy use — especially when chatty MCP servers spawned by langgraph dev filled it, or when failure paths produced stack traces. Implement the recommended option 1 from #209: filesize-based rollover. When the active log exceeds 50MB on the next ``start_langgraph_dev`` invocation, rename it to ``langgraph_dev.log.1`` (overwriting any existing backup) via ``os.replace`` and start fresh. Single-backup policy keeps the disk footprint bounded at roughly 2x threshold. Rotation is best-effort: ``_rotate_log_if_needed`` logs and swallows OSError so a permission error or racing rename can't block langgraph dev from starting. The next ``start`` invocation will try again — worst case the log grows for one more session. Options 2 (timestamped per-session + 7-day sweep) and 3 (``RotatingFileHandler`` + pipe) are explicitly NOT done — option 1 is simplest, no async machinery, matches the issue's recommendation. Closes #209 * test(langgraph-dev): redirect _PID_DIR in rotate integration test Address CodeRabbit review comment on #270: the ``TestStartLanggraphDevRotatesLog::test_rotate_called_before_open`` test patched only ``_LOG_FILE`` to a tmp path, but ``start_langgraph_dev`` also calls ``_PID_DIR.mkdir(...)`` as part of its prelude, which would create a real directory under ``~/.config/evoscientist/`` on a dev machine. Redirect ``_PID_DIR`` to ``tmp_path / "pids"`` too so the test stays fully isolated. Add a final assertion that ``pid_dir.is_dir()`` holds, proving the function reached past the mkdir call. * refactor(langgraph-dev): bundle runtime paths into LanggraphRuntimePaths @din0s review follow-up on #270: the previous test isolation patched only ``_LOG_FILE`` (and after a second round, ``_PID_DIR``), but ``start_langgraph_dev`` still touches 5 distinct on-disk paths. Patching any subset of those still leaves the others pointing at the user's real ``~/.config/evoscientist/`` — exactly the case that produced the "Port 6174 cannot be bound after waiting 60s" symptom on the reviewer's machine. Replace the five free-floating module-level constants (``_PID_DIR`` / ``_PID_FILE`` / ``_LOG_FILE`` / ``_WORKSPACE_SIDECAR`` / ``_FILE_LOCK_PATH``) with a single ``LanggraphRuntimePaths`` frozen dataclass exposed as a module-level ``RUNTIME`` instance. Production code accesses ``RUNTIME.pid_file`` etc.; tests can now substitute the *whole* bundle in one assignment: monkeypatch.setattr( manager, "RUNTIME", manager.LanggraphRuntimePaths.for_directory(tmp_path / "runtime"), ) The classmethod ``for_directory(pid_dir)`` builds an isolated bundle rooted at a single dir, so the test author doesn't spell out every path field. Tests that only care about one field (e.g. pid_file during the stale-process kill path) use ``dataclasses.replace(manager.RUNTIME, pid_file=X)`` — frozen dataclass-friendly, no need to enumerate the other four fields. The dataclass's docstring records the migration rationale (the old five-name layout invited inconsistent patches). External callers of the old constants updated: - ``EvoScientist/deploy/server.py`` and ``webui.py`` now import ``RUNTIME`` and use ``RUNTIME.log_file`` for the on-screen log path hint. The other imports they had (``_DEFAULT_PORT``, ``_is_port_occupied``, ``_read_workspace_sidecar``) are still module-level functions/values, untouched. Test updates: - ``tests/test_langgraph_manager.py``: ``patch.object(manager, "_XXX", X)`` patterns now go through ``dataclasses.replace(manager.RUNTIME, xxx=X)``; the ``TestStartLanggraphDevRotatesLog::test_rotate_called_before_open`` test (from the previous #270 review iteration) uses ``for_directory`` for one-shot isolation. - ``tests/test_langgraph_dev_workspace_sidecar.py``: each test now goes through a tiny ``_isolated_runtime(monkeypatch, tmp_path)`` helper that calls ``for_directory``. - ``tests/test_langgraph_dev_deploy_mode.py``: same ``for_directory`` swap. No production behavior change. All ``langgraph_dev``-side tests (``test_langgraph_manager.py`` 26/26, ``test_langgraph_dev_workspace_sidecar.py`` 14/14, ``test_langgraph_dev_deploy_mode.py`` 14/14, ``test_cli_deploy.py`` 18/18 — which indirectly exercises deploy/server.py and deploy/webui.py imports) pass. Full-project test count unchanged from baseline; the remaining 22 Windows-only pre-existing failures (test_background ``os.killpg``, test_file_mentions tilde, mcp_client ``shutil.which``, test_sessions 8.3 short path) are documented as out-of-scope for #207. * style: apply ruff format to langgraph_dev test + module files CI lint check on #270 failed: Run ruff format --check . Would reformat: EvoScientist/langgraph_dev/manager.py Would reformat: tests/test_langgraph_manager.py Plus two test files touched by the prior consolidation commit that ``ruff format`` hadn't seen yet: tests/test_langgraph_dev_deploy_mode.py tests/test_langgraph_dev_workspace_sidecar.py Just formatting. No logic change. All 75 refactor-related tests pass. * fix(test): use for_directory for full path isolation + patch _can_bind_port to skip real socket ops Two fixes for TestStartLanggraphDevRotatesLog: 1. Replace dataclasses.replace(manager.RUNTIME, ...) with LanggraphRuntimePaths.for_directory(pid_dir) so pid_file, workspace_sidecar, and lock_file are also temp-rooted (prevents leak to ~/.config/evoscientist/). 2. Monkeypatch _can_bind_port to always return True so the bind-poll loop in _wait_for_port_bindable passes immediately without touching real sockets (fixes 60s timeout on machines where port 6174 is already in use). * fix: cross-platform compatibility for Windows CI runners - background.py: replace POSIX-only os.killpg/os.getpgid with cross-platform _kill_process_tree() helper. On Windows falls back to Popen.terminate()/Popen.kill() (TerminateProcess); on POSIX keeps existing os.killpg logic. - test_backends.py: replace mkdir -p shell execution in test_literal_workspace_path_replaced with preprocessing-boundary assertion (patch LocalShellBackend.execute, capture command, assert workspace path was rewritten to ./). Avoids POSIX-only mkdir -p on Windows runners. - test_file_mentions.py: monkeypatch USERPROFILE on Windows so ntpath.expanduser() resolves ~ to tmp_path even when HOME is unset on CI runners. * refactor(test): add runtime_paths fixture to isolate manager.RUNTIME Adds a reusable fixture that monkeypatches manager.RUNTIME to a temp-rooted LanggraphRuntimePaths.for_directory(). Tests that need specific fields can still dataclasses.replace(runtime_paths, ...) but the baseline is always temp-isolated, preventing leaks to ~/.config/evoscientist/. Updated test_langgraph_dev_deploy_mode.py, test_langgraph_dev_workspace_sidecar.py, and test_langgraph_manager.py to use the fixture, consolidating sequential lock_file + pid_dir patches into single dataclasses.replace calls. * Revert "fix: cross-platform compatibility for Windows CI runners" This reverts commit eb025d24af32e195a982cd40f6d70dba885c4019. * style: ruff format conftest.py * fix: address review issues in log-rotation + runtime paths - Use for_directory(tmp_path/pids) as base in ensure_langgraph_dev tests so pid_file/log_file are co-located with pid_dir, not split across paths - Remove unused runtime_paths param from test_no_existing_file_is_noop - Replace manager.RUNTIME with runtime_paths in two sidecar tests - Use for_directory(DEFAULT_PID_DIR) instead of explicit construction - Fix stale _LOG_FILE reference in TestRotateLogIfNeeded docstring * style: ruff format test files --------- Co-authored-by: Xi Zhang <106144707+X-iZhang@users.noreply.github.com> |

feat(deploy): add EvoSci deploy subcommand (#228)
* feat(deploy): implement standalone LangGraph server and CLI command for deployment * feat(deploy): enhance port validation and environment variable management for deployment * Refactor langgraph dev deployment and introduce workspace sidecar protocol - Updated the deployment mode handling in `server.py` to use a single environment variable `EVOSCIENTIST_DEPLOY_MODE` with values `full` and `stripped`. - Enhanced the `manager.py` to implement a workspace fingerprint sidecar, allowing cross-process reuse of langgraph dev instances while ensuring workspace consistency. - Introduced functions to write and read the workspace sidecar, with error handling for missing or corrupt data. - Added tests for the workspace sidecar functionality, including validation of the JSON schema and ensuring proper error handling for workspace mismatches. - Updated existing tests to reflect changes in deployment mode handling and added new tests for signal handling during shutdown. - Ensured that cleanup routines remove the workspace sidecar alongside the PID file during shutdown. * fix(langgraph): improve workspace sidecar checks for process ownership and stale handles |
