Summary by CodeRabbit

  • New Features

    • Panel installation now verifies existing panels through configured hosts, resolved addresses, and loopback.
    • Panel startup waits for health checks to pass and provides diagnostics if startup fails.
    • Health-check URLs support IPv6 addresses and correctly handle HTTP or HTTPS ports.
  • Bug Fixes

    • Existing installations are stopped safely before updates, including inactive services.
    • Binary replacement is more reliable and preserves executable permissions.
    • Temporary download and replacement files are cleaned up automatically.

Panel installation reliability

Layer / File(s) Summary
Atomic binary replacement
pkg/utils/fs.go, pkg/utils/fs_*test.go, pkg/panel/install.go, internal/actions/daemon/install/daemon_install.go
Binary installation uses utils.ReplaceFile with mode 0755. The helper stages, replaces, and cleans up files. Download directories are removed after use.
Health URL construction
internal/pkg/panel/install.go, internal/pkg/panel/install_internal_test.go
Health URLs normalize IPv6 hosts and select default ports according to the HTTP or HTTPS scheme.
Panel lifecycle and detection
internal/actions/panel/install/checkers_v4.go, internal/actions/panel/install/health_v4.go, internal/actions/panel/install/panel_install_v4.go, internal/actions/panel/install/*_internal_test.go
V4 installation stops previous panels, validates scope and port, probes saved hosts and loopback, and polls the health endpoint with retries and cancellation handling. Tests cover service states, host selection, SPA fallback rejection, and health readiness.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 30322

A failed installation can stop an otherwise working panel before the replacement is ready, leaving the panel unavailable. The PR should not merge until shutdown occurs at the final replacement boundary or failure paths reliably restart the previous panel.

In `@internal/actions/panel/install/panel_install_v4.go`:
- Line 338: Update HandleV4 so stopPreviousPanelV4 occurs only after preflight
and immediately before binary replacement, while preserving previous-panel port
detection earlier in the flow. Ensure any pre-install failure, including
packagemanager.Load errors, leaves the previously running same-scope panel
available; if stopping earlier is unavoidable, restart it before returning the
error.

In `@internal/pkg/panel/install.go`:
- Around line 201-202: Update the hostPort construction in createHealthURL to
omit the port only when it matches the default port for the selected scheme,
while preserving explicit ports for cross-scheme combinations; extend
Test_createHealthURL with HTTP on 443 and HTTPS on 80 cases.

In `@pkg/utils/fs.go`:
- Line 81: Update ReplaceFile to create a unique staging file within
filepath.Dir(dst) for each replacement instead of using the shared dst + ".new"
path. Track that exact generated path for all rename/remove operations and
cleanup, preserving the existing replacement behavior under concurrent calls.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Restore service availability when a later installation step fails.

stopPreviousPanelV4 stops a working panel before later failure points. If packagemanager.Load fails at Line 362, or another pre-install step fails, HandleV4 returns and leaves the previous panel stopped.

Move this stop closer to binary replacement after preflight work, while retaining previous-panel port detection. If the stop must occur here, restart the same-scope panel on later pre-install failures.
