From 4af4ddb0606db0da7aac4d418183435114239808 Mon Sep 17 00:00:00 2001 From: Marc Mintel Date: Sat, 2 May 2026 19:57:33 +0200 Subject: [PATCH] fix: prevent SessionStateEncoder crash from non-serializable datetime on args MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: bot_flow.py injected configs.args.global_start_time = datetime.now() which polluted the args namespace. SessionStateEncoder blindly serialized args.__dict__ via json.dump, which crashed mid-write on the datetime object, leaving sessions.json truncated/corrupt. Every subsequent restart failed. Fixes: - Remove global_start_time from configs.args (only lives on engine class vars) - Harden SessionStateEncoder with _sanitize_value() to convert any non-JSON-serializable type (datetime, timedelta, arbitrary objects) to strings - Add test_system_session_persistence.py with 4 tests covering the exact production crash scenario (datetime injection → json.dumps → round-trip) - Fix test_engine_timeout.py broken GoalExecutor module reference --- GramAddict/core/bot_flow.py | 1 - GramAddict/core/session_state.py | 24 +++- tests/e2e/test_engine_timeout.py | 14 +- tests/e2e/test_system_session_persistence.py | 140 +++++++++++++++++++ 4 files changed, 171 insertions(+), 8 deletions(-) create mode 100644 tests/e2e/test_system_session_persistence.py diff --git a/GramAddict/core/bot_flow.py b/GramAddict/core/bot_flow.py index 6b9b755..1b6aa2d 100644 --- a/GramAddict/core/bot_flow.py +++ b/GramAddict/core/bot_flow.py @@ -307,7 +307,6 @@ def start_bot(**kwargs): try: bot_start_time = datetime.now() - configs.args.global_start_time = bot_start_time max_runtime = getattr(configs.args, "max_runtime_minutes", None) dopamine.global_start_time = bot_start_time diff --git a/GramAddict/core/session_state.py b/GramAddict/core/session_state.py index 3caf81f..19bebba 100644 --- a/GramAddict/core/session_state.py +++ b/GramAddict/core/session_state.py @@ -277,7 +277,29 @@ class SessionState: class SessionStateEncoder(JSONEncoder): + """JSON encoder for SessionState that is crash-proof against non-serializable types.""" + + _SAFE_TYPES = (str, int, float, bool, type(None)) + + @classmethod + def _sanitize_value(cls, value): + """Convert any non-JSON-serializable value to a safe string representation.""" + if isinstance(value, cls._SAFE_TYPES): + return value + if isinstance(value, datetime): + return value.isoformat() + if isinstance(value, dict): + return {k: cls._sanitize_value(v) for k, v in value.items()} + if isinstance(value, (list, tuple)): + return [cls._sanitize_value(v) for v in value] + # Last resort: stringify unknown objects to prevent json.dump mid-write crashes + return str(value) + def default(self, session_state: SessionState): + # Sanitize args dict — never trust raw __dict__, it may contain datetime or other garbage + raw_args = session_state.args.__dict__ if hasattr(session_state.args, "__dict__") else {} + safe_args = {k: self._sanitize_value(v) for k, v in raw_args.items()} + return { "id": session_state.id, "total_interactions": sum(session_state.totalInteractions.values()), @@ -291,7 +313,7 @@ class SessionStateEncoder(JSONEncoder): "total_scraped": session_state.totalScraped, "start_time": str(session_state.startTime), "finish_time": str(session_state.finishTime), - "args": session_state.args.__dict__, + "args": safe_args, "profile": { "posts": session_state.my_posts_count, "followers": session_state.my_followers_count, diff --git a/tests/e2e/test_engine_timeout.py b/tests/e2e/test_engine_timeout.py index f78c367..5d11ff8 100644 --- a/tests/e2e/test_engine_timeout.py +++ b/tests/e2e/test_engine_timeout.py @@ -112,9 +112,12 @@ def test_workflow_lifecycle_hard_kill(e2e_device, monkeypatch): if hasattr(bot_flow, loop_func): monkeypatch.setattr(bot_flow, loop_func, lambda *args, **kwargs: "BOREDOM_CHANGE_FEED") - monkeypatch.setattr(bot_flow.GoalExecutor, "achieve", lambda *args, **kwargs: True) - monkeypatch.setattr(bot_flow.QNavGraph, "navigate_to", lambda *args, **kwargs: True) - monkeypatch.setattr(bot_flow.QNavGraph, "do", lambda *args, **kwargs: True) + from GramAddict.core.goap import GoalExecutor + from GramAddict.core.q_nav_graph import QNavGraph + + monkeypatch.setattr(GoalExecutor, "achieve", lambda *args, **kwargs: True) + monkeypatch.setattr(QNavGraph, "navigate_to", lambda *args, **kwargs: True) + monkeypatch.setattr(QNavGraph, "do", lambda *args, **kwargs: True) # 4.
