# windows.ps1 -- repo-owned Windows Desktop update hand-off.
|
|
#
|
|
# WHY THIS EXISTS (the frozen-binary problem): the Desktop's Update button
|
|
# used to hand off exclusively to the staged Tauri binary
|
|
# (%HERMES_HOME%\hermes-setup.exe). That binary has no self-update path --
|
|
# copy_self_to_hermes_home deliberately no-ops during --update -- so every
|
|
# updater-side fix (cache refresh #67369, marker self-adopt #74782, straggler
|
|
# handling) only reaches users when a new installer is built, signed, and
|
|
# published. In practice binaries go months stale and users hit long-fixed
|
|
# bugs on every update (the 2026-08-09 incident chain).
|
|
#
|
|
# This script lives in the repo checkout, so EVERY `hermes update` refreshes
|
|
# the very code that drives the next update. The Desktop spawns it through a
|
|
# `cmd start` wrapper (see wrapHandoffForDetachedConsole in
|
|
# apps/desktop/electron/updater-process.ts -- a bare detached+hidden
|
|
# powershell dies before -File runs) and exits; only PowerShell itself -- an
|
|
# OS component -- is "frozen".
|
|
#
|
|
# CONTRACT (keep in sync with apps/desktop/electron/main.ts):
|
|
# cmd /d /s /c start "" /min powershell -NoProfile -ExecutionPolicy Bypass
|
|
# -File scripts\desktop-update\windows.ps1
|
|
# -InstallRoot <path> repo checkout (HERMES_HOME\hermes-agent)
|
|
# -Branch <ref> branch to update against
|
|
# -DesktopPid <pid> the Electron main process to wait out
|
|
# [-RelaunchExe <path>] Hermes.exe to start when done (omit = no relaunch)
|
|
# [-NoUi] headless (tests); default shows a progress window
|
|
# [-NoMarkerCleanup] leave .hermes-update-in-progress in place (tests)
|
|
#
|
|
# SAFETY POSTURE: both preflight gates FAIL CLOSED. A Desktop that never
|
|
# exits, or a venv shim that never unlocks, aborts the hand-off without
|
|
# mutating the install -- a skipped update is recoverable, a half-updated
|
|
# venv is not. Every exit path (success, abort, crash) writes
|
|
# .hermes-update-result.json for the relaunched Desktop to surface, and
|
|
# relaunches the Desktop so the user is never left stranded.
|
|
#
|
|
# Marker: we claim HERMES_HOME\.hermes-update-in-progress with OUR pid as
|
|
# step 0 (the wrapper cmd.exe pid the Desktop saw is useless -- it exits
|
|
# immediately). hermes_cli/update_lock.py's ancestry rule lets our
|
|
# `hermes update` child adopt the claim; electron/update-marker.ts parks a
|
|
# relaunched Desktop on it. Cleanup only removes the marker while WE still
|
|
# own it (a handoff partner that rewrote it keeps its claim).
