fix: bound devicectl calls with a timeout + cache the iOS app list#19
Merged
Conversation
Jaca polls `devicectl list devices` on the discovery loop and runs `device info apps` for the app picker, but CommandRunner had no timeout. When CoreDevice stalls (common with devicectl), those calls hang forever and pile up zombie processes -- which wedges CoreDevice further, so `device info apps` then times out and the iOS app picker shows "No apps found on this device". - CommandRunner.run gains an optional `timeout` that SIGKILLs a wedged child, so a hung tool can't block the call or accumulate. Applied to every devicectl site: list devices (discovery poll), info apps, lockState poll, and the device-availability checks. - The iOS app list is cached to disk per device; a slow/empty/failed query falls back to the last good list so the picker never blanks while devicectl flakes.

Building on the devicectl timeout + cache (#19), make the picker resilient to a slow/flaky devicectl instead of just bounding it: - Retry the `device info apps` query once. devicectl's first call after a cold start often stalls warming the tunnel, then the retry returns fast — so a single transient timeout no longer drops to an empty list. - Cache-first: show the last good list instantly while a refresh runs, and keep it shown if the refresh fails — no blank "No apps found" flash when we have a cache. - Reopening the picker re-fetches whenever the list is empty, and the empty state now has a Retry button — so a wedged-then-recovered devicectl is one click (or reopen) away from populating.

Problem
The iOS-device app picker shows "No apps found on this device" even though the apps are installed.
Root cause is a robustness gap, surfaced by
devicectlbeing flaky (CoreDevice stalls):devicectl list deviceson the discovery loop and runsdevicectl device info appsfor the picker — butCommandRunner.runhad no timeout.devicectlwedges, those calls hang forever and pile up zombie processes (observed 5+ stucklist devicesat once). That congestion wedges CoreDevice further, sodevice info appsthen times out and the picker comes back empty.Fix
CommandRunner.run— an optionaltimeoutSIGKILLs a child that runs too long, so a hung tool can't block the call or accumulate. Applied to everydevicectlsite:list devices(discovery poll, 12s),device info apps(25s),lockStatepoll (8s), and the device-availability checks (12s).devicectlflakes.Notes
