From f22f76c56b3476e1efb7a006d15159626d108903 Mon Sep 17 00:00:00 2001 From: Mohamed Boudra Date: Thu, 25 Dec 2025 19:14:51 +0700 Subject: [PATCH] Fix Codex MCP timeline persistence after daemon restart MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When daemon restarts, SESSION_HISTORY is lost because it's an in-memory Map. This fix adds disk-based timeline loading from Codex rollout files. Changes: - Add loadPersistedHistoryFromDisk() method to load from rollout files - Add helper functions for finding and parsing rollout JSONL files - Call disk loading in connect() when resumeHandle exists but SESSION_HISTORY is empty - Add E2E test for timeline persistence across daemon restart The rollout files are stored at ~/.codex/sessions//rollout-*.jsonl and contain JSONL entries with response_item and event_msg types. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../server/agent/providers/codex-mcp-agent.ts | 310 +++++++++++++++++- packages/server/src/server/daemon.e2e.test.ts | 122 +++++++ plan.md | 23 +- 3 files changed, 445 insertions(+), 10 deletions(-) diff --git a/packages/server/src/server/agent/providers/codex-mcp-agent.ts b/packages/server/src/server/agent/providers/codex-mcp-agent.ts index ea52ea79c..f1f01eb3f 100644 --- a/packages/server/src/server/agent/providers/codex-mcp-agent.ts +++ b/packages/server/src/server/agent/providers/codex-mcp-agent.ts @@ -1,5 +1,9 @@ import { execSync } from "node:child_process"; import { randomUUID } from "node:crypto"; +import { promises as fs } from "node:fs"; +import type { Dirent } from "node:fs"; +import os from "node:os"; +import path from "node:path"; import { Client } from "@modelcontextprotocol/sdk/client/index.js"; import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js"; @@ -1922,6 +1926,25 @@ function extractFileReadFromParsedCmd(parsedCmd: ParsedCmdItem[] | undefined): { return null; } +function shouldReportCommandError(input: { + exitCode?: number; + success?: boolean; + status?: string; + error?: unknown; +}): boolean { + if (input.error !== undefined) { + return true; + } + const statusFailed = input.status === "failed"; + if (input.exitCode === undefined) { + return input.success === false || statusFailed; + } + if (input.exitCode === 0) { + return input.success === false || statusFailed; + } + return false; +} + function buildFileChangeSummary(files: { path: string; kind: string }[]): string { if (files.length === 1) { return `${files[0].kind}: ${files[0].path}`; @@ -2514,6 +2537,7 @@ class CodexMcpAgentSession implements AgentSession { private pendingPatchChanges = new Map(); private patchChangesByCallId = new Map(); private managedAgentId: string | null = null; + private resumeHandle: AgentPersistenceHandle | null = null; constructor(config: CodexMcpAgentConfig, resumeHandle?: AgentPersistenceHandle) { this.config = config; @@ -2522,6 +2546,7 @@ class CodexMcpAgentSession implements AgentSession { this.pendingLocalId = `codex-${randomUUID()}`; if (resumeHandle) { + this.resumeHandle = resumeHandle; this.sessionId = resumeHandle.sessionId; const metadata = resumeHandle.metadata; if (metadata) { @@ -2538,9 +2563,11 @@ class CodexMcpAgentSession implements AgentSession { this.conversationId = this.sessionId; } } + // Try in-memory history first (for same-process resume) const history = this.sessionId ?
