The existing log send counter and error coverage remain in place. No log text, stack traces or device IDs go to Sentry. +Since 0.1.161, each visible simulator panel opens an app-only crash session for its booted iOS simulator or Android device, independent of Logs; log sessions run the same crash watcher scoped to their app or process. `logs.crash.detected` counts crash records, with `device_platform` and `crash_source`: `ios_exit` for SpringBoard's immediate crash-signal exit line, `ios_log` for the app's own crash message read from the unified log about a second later (uncaught exceptions, Swift fatal errors, React Native fatal JS errors; none for an external signal), `ios_report` for the `.ips` report written 30-45 seconds later, and `android_logcat` for `FATAL EXCEPTION` blocks and libc fatal signals. One iOS crash therefore usually records several sources. `logs.crash.parse` measures `.ips` parsing in milliseconds, the only expensive parse. Both use the `logs` surface and are recorded per crash because crashes are rare. In the UI, `ui.crash.toast_shown`, `ui.crash.attached`, `ui.crash.sent_to_chat`, `ui.crash.dismissed`, `ui.crash.report_attached` (a stack arriving for a toast already shown) and `ui.crash.watch_retry` count toast activity and session recovery; chat delivery time stays under `ui.logs.send`. Crash sessions long-poll for up to 20 seconds and pause reads while the document is hidden, sending only keep-alives. Crash messages, stack traces, app IDs, process names, report paths and device IDs stay local. + `ui.logs.session_expired` counts expired sessions that trigger automatic recovery. It uses the active Logs context without sending session IDs, error text or log content. `ui.logs.retention` measures bounded buffer updates in milliseconds. `ui.logs.evicted` counts rows removed locally to meet the shared row and text limits; `ui.logs.dropped` still counts only rows lost from the server buffer. Existing filter timing and row gauges cover the resulting list. These measurements contain no log text or source metadata. diff --git a/package-lock.json b/package-lock.json index bd6e876..56f680d 100644 --- a/package-lock.json +++ b/package-lock.json @@ -1,12 +1,12 @@ { "name": "codex-mobile-dev-plugin", - "version": "0.1.160", + "version": "0.1.161", "lockfileVersion": 3, "requires": true, "packages": { "": { "name": "codex-mobile-dev-plugin", - "version": "0.1.160", + "version": "0.1.161", "dependencies": { "@base-ui/react": "^1.8.0", "@fontsource-variable/inter": "^5.3.0", diff --git a/package.json b/package.json index c906332..5115495 100644 --- a/package.json +++ b/package.json @@ -1,6 +1,6 @@ { "name": "codex-mobile-dev-plugin", - "version": "0.1.160", + "version": "0.1.161", "private": true, "type": "module", "engines": { diff --git a/scripts/smoke-package.mjs b/scripts/smoke-package.mjs index ed65268..aafc7ae 100644 --- a/scripts/smoke-package.mjs +++ b/scripts/smoke-package.mjs @@ -146,7 +146,7 @@ try { assert.deepEqual(workspace._meta["openai/ui"].entrypoints, [{ type: "global" }]); const workspaceResource = await client.readResource({ uri: workspace._meta.ui.resourceUri }); assert.ok(workspaceResource.contents[0].text.includes('data-view="workspace" data-layout="split"')); - for (const name of ["mobile_log_sources", "mobile_logs_session", "mobile_read_logs", "mobile_logs_keep_alive", "mobile_logs_close", "mobile_performance_sources", "mobile_cpu_session", "mobile_read_cpu", "mobile_cpu_close"]) { + for (const name of ["mobile_log_sources", "mobile_logs_session", "mobile_read_logs", "mobile_logs_keep_alive", "mobile_logs_close", "mobile_crashes_session", "mobile_performance_sources", "mobile_cpu_session", "mobile_read_cpu", "mobile_cpu_close"]) { assert.ok(tools.tools.some(tool => tool.name === name), `Missing developer tool: ${name}`); } const panel = await client.callTool({ name: "mobile_open_simulator", arguments: {} }, undefined, { timeout: 30000 }); diff --git a/src/server/crash-reports.ts b/src/server/crash-reports.ts new file mode 100644 index 0000000..e1a6911 --- /dev/null +++ b/src/server/crash-reports.ts @@ -0,0 +1,297 @@ +import { execFile } from "node:child_process"; +import { watch } from "node:fs"; +import type { FSWatcher } from "node:fs"; +import { readFile, stat } from "node:fs/promises"; +import { homedir } from "node:os"; +import { join } from "node:path"; +import { promisify } from "node:util"; +import type { CrashWatchTarget, LogRecord, NativeLogTarget } from "../shared/logs.ts"; +import { parseLogcat } from "./log-parsers.ts"; +import { adbPath, keepReading, runLogProcess } from "./native-logs.ts"; +import type { StopLogSource } from "./native-logs.ts"; +import { recordCrash } from "./telemetry.ts"; + +const execute = promisify(execFile); +export const iosCrashReportDirectory = join(homedir(), "Library/Logs/DiagnosticReports"); +const frameLimit = 60; +type Emit = (crash: LogRecord) => void; + +/** Watch one device for app crashes.
