brooklyn! 98528c78c1 fix(desktop/windows): stop racing our own backend during in-app update (#39828) ... * fix(desktop/windows): stop racing our own backend during in-app update The Windows in-app update (Update button -> hermes-setup.exe --update handoff) bricked because it raced a still-locked hermes.exe: the desktop quit fire-and-forget without reaping its backend child + grandchildren, so when the updater ran `hermes update`, the venv shim was still open. The quarantine rename then failed, uv's `pip install -e .` hit "Access is denied", the git path bailed to a full ZIP re-download, and the deps still couldn't write the locked shim -- leaving a half-applied install. macOS is fine because it never blocks REPLACE on a running executable. Three coordinated fixes restore Mac-style parity (click Update -> progress -> relaunch, no terminal): A. Desktop (main.cjs): before spawning the updater, releaseBackendLockForUpdate() tree-kills the primary + pool backends (taskkill /T /F on Windows, to catch REPL/pty/gateway grandchildren that SIGTERM misses) and polls the venv shim until it is actually writable (bounded 15s) -- so the lock is gone before we hand off. Also fixes resolveHermesCliBinary to use venv\Scripts\hermes.exe on Windows. B. Updater (update.rs): wait_for_venv_free no longer "proceeds anyway" on timeout -- it force-kills any lingering hermes.exe (excluding itself) and re-checks, so a straggler can't doom the install. C. Updater (update.rs): pass --force to `hermes update`. By contract the desktop has exited + waited, and the wait force-kills stragglers, so the running-exe guard would only produce a false "Hermes is still running" dead-end. Verified: node --check on main.cjs, cargo check on the updater (clean), and the Windows-gated taskkill body type-checks standalone. Field repro: ryanc's update.log (manual + handoff both hit the same lock cascade). * review: scope backend kill+wait to Windows; drop meaningless POSIX pgid kill		2026-06-05 08:33:53 -05:00
