ethernet 6b54582438 fix: tool_calls double-encoding on import (#68856) ... * nix: add `cage` to devShell * test(desktop): add pre-filled sessions support Exports createSandbox, writeMockProviderConfig, writeEnvFile, buildAppEnv, findElectron, and launchDesktop from fixtures.ts so specs can compose their own seeded-backend fixtures without duplicating the sandbox/config/launch logic. * test(desktop): auto-fail e2e tests on error banner Adds a shared test fixture (e2e/test.ts) that wraps @playwright/test's page with an error-banner guard. When any [role="alert"] element (error notification toast) appears in the DOM during a test, the test fails with the error message text. The guard uses: - A MutationObserver (injected via addInitScript) that watches for [role="alert"] elements appearing at any point during the test - A final DOM scan in afterEach for alerts still visible at teardown - Deduplication so the same error text only fires once All existing e2e specs updated to import { test, expect } from './test' instead of '@playwright/test'. No per-spec setup needed — the guard is auto-installed on every page via the extended fixture. This catches issues like the "resume failed" error banner that can appear during session loading — previously the test would pass while an error toast was silently visible on screen. * fix(state): parse tool_calls JSON string before re-serializing _insert_message_rows and append_message both do json.dumps(tool_calls) to serialize the field for SQLite storage. But when tool_calls arrives as a JSON string (from import_sessions / export_session, which store it as TEXT), json.dumps double-encodes it — wrapping the already-serialized string in quotes and escaping the inner quotes. When _rows_to_conversation later does json.loads(row['tool_calls']), the double-encoded string parses back to a plain string (not a list). _history_to_messages then iterates this string character-by-character, calling tc.get('function', {}) on each char — 'str' object has no attribute 'get'. This was a pre-existing bug (on main), but only triggered by the import_sessions path (the live agent always passes tool_calls as a Python list). The e2e error-banner guard caught it via the 'Resume failed' notification toast. Fix: in both append_message and _insert_message_rows, parse tool_calls with json.loads first if it's a string, then re-serialize. * fix(desktop): exempt boot-failure from error guard - boot-failure: add allowErrorBanners() beforeEach — these tests deliberately trigger boot errors, so error toasts are expected - test.ts: export allowErrorBanners() opt-out + reset flag in afterEach		2026-07-21 18:53:05 +00:00
