""" From 51723850df42de6084d4de40d1829ecc94a54f5b Mon Sep 17 00:00:00 2001 From: george Date: Thu, 18 Dec 2025 21:41:40 +0000 Subject: [PATCH 59/68] fix: Codex backend event limit and DictConfig serialization bugs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add max_events attribute to AgenticConfig (was missing, caused AttributeError) - Fix agentic.py to use max_events instead of max_turns for Codex event limit - Increase default max_events from 80 to 240 (3x) for longer sessions - Add _to_primitive() helper to convert OmegaConf DictConfig to JSON-serializable types - Extract session_id parsing to shared event_utils.py module - Handle Codex CLI non-zero exit gracefully when events were processed - Consolidate CodexAuthError into codex_cli.py (was in deleted codex_device_auth.py) These fixes enable Codex backend to complete full evolution runs without crashes. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- shinka/core/runner.py | 20 +++- shinka/edit/agentic.py | 30 +----- shinka/edit/codex_cli.py | 203 +++++++++++++++++++++++++++++++------ shinka/edit/event_utils.py | 42 ++++++++ 4 files changed, 233 insertions(+), 62 deletions(-) create mode 100644 shinka/edit/event_utils.py diff --git a/shinka/core/runner.py b/shinka/core/runner.py index 4efd283ea..65d55bced 100644 --- a/shinka/core/runner.py +++ b/shinka/core/runner.py @@ -33,10 +33,12 @@ summarize_diff, ) from shinka.edit.codex_cli import ( + CodexAuthError, CodexExecutionError, CodexUnavailableError, ensure_codex_available, run_codex_task, + validate_codex_setup, ) from shinka.edit.shinka_agent import ( ShinkaExecutionError, @@ -89,6 +91,7 @@ class AgenticConfig: sandbox: str = "workspace-write" approval_mode: str = "full-auto" max_turns: int = 50 + max_events: int = 240 # Event limit for Codex CLI streaming (3x default) max_seconds: int = 0 cli_path: Optional[str] = None extra_cli_config: Dict[str, Any] = field(default_factory=dict) @@ -110,7 +113,7 @@ class AgenticEvaluatorConfig: cli_profile: Optional[str] = None sandbox: str = "workspace-write" approval_mode: str = "full-auto" -
