- updater-fallback.mjs (82 assertions): GitHub probe fallback to Gitea,
timeout budgets, in-flight check never stuck in 'checking'; updater.ts
gains a setUpdateTimeouts test seam, electron-updater aliased to a stub
- ipc-guard.mjs (43): trusted-frame guard exercised through real
registerIpc handlers with forged senderFrames; electron-stub now records
registrations via globalThis so bundle and test share one instance
- log-sanitizer.mjs (71): CSI/OSC/charset state machine, alt-screen fold,
byte-split fuzz equal to whole-chunk output; fixes a wrong comment
- sftp-timeout.mjs (39): per-op timeouts (metadata 30s, transfer chunk 60s,
open 10s) evict half-dead channels with one retry, slow-but-progressing
transfers untouched, late rejections never unhandled
- reservedAccelerators.ts: single pure isReservedAccelerator shared by the
settings recorder and applyGlobalShortcut (the two tables had drifted —
main now also refuses Ctrl+=/-/0/PgUp/PgDn legacy values); 56 assertions
- ssh-loopback.mjs loads the real ssh.ts via a bundle (50 assertions):
TOFU pinning, fail-closed stores, auth gate, connect budget
Offline suite grows 13 -> 17. Renderer test framework evaluated: not
introducing vitest/jsdom; pure logic keeps being extracted and tested
through the existing bundle harness.
Lock screen (main-window overlay, no second window):
- scrypt password verifier in <userData>/lock.json (per-write salt,
timingSafeEqual); salt/hash/password never leave the main process
- lock now / idle auto-lock / lock at startup, growing failure cooldown,
lock flags persisted so a quit-and-relaunch cannot bypass the lock
- locked shell and body portals go inert while sessions keep running;
menu accelerators (reload, DevTools, zoom) are swallowed while locked
- settings gains a Lock tab; all copy in zh-CN/zh-TW/en/ja
Security and stability:
- packaged builds ignore ELECTRON_RENDERER_URL / OT_UPDATE_URL (devEnv)
- renderer preload runs with sandbox: true
- unreadable known_hosts store fails closed instead of being overwritten
- connect-time secrets gated by the bookmark's auth method (connectPromptFor)
- ssh stream teardown is idempotent: PTY_EXIT broadcasts exactly once
- sysinfo polling is refcounted for split panes (forceStopPolling on close)
- session-log index entries are path-contained; settings store writes
atomically with EPERM/EBUSY retry
- sync-changelog tolerates CRLF checkouts (was a silent no-op)
- retry ssh2 host-key generation (flaky malformed key, ~1/500)
Tests: lock-store + lock-controller suites; transport-death PTY_EXIT e2e;
GitHub Actions CI (typecheck + 10 offline tests + build)
