Why

Restart to Update on 0.22.0 → 0.23.0 downloaded the zip, then ShipIt failed with No space left on device. The handler destroyed every window first, so the error never appeared.

Fix

  • Do not destroy windows before quitAndInstall
  • Skip the before-quit flush while ShipIt is installing
  • Refuse download/install under 1 GB free
  • Show a disk-full / incomplete-zip message

Squash-merge. Not a backmerge.

Summary by CodeRabbit

  • New Features

    • Added disk-space checks before downloading or installing updates.
    • Update errors now provide clearer messages, including available free space and incomplete-download details.
    • Update installation failures are reported directly in the update banner and Settings.
  • Bug Fixes

    • Improved update installation reliability by preserving the normal installation flow and shutdown handling.
    • Added coverage for disk-space, download, and unrelated updater errors.

ShipIt ditto failed with ENOSPC after Restart to Update destroyed every window, so the error never showed and the app looked dead. Check free space before download/install, skip the before-quit intercept while ShipIt runs, and surface a disk-full message.

📝 Walkthrough

Walkthrough

The updater now checks temporary-directory disk space, formats common updater errors, returns installation outcomes through IPC, preserves installation state during shutdown, and displays returned errors in update UI components.

Changes

Updater handling

Layer / File(s) Summary
Disk guard and updater error formatting
apps/desktop/src/main/handlers/updaterError.ts, apps/desktop/src/main/handlers/updateHandlers.ts, apps/desktop/src/main/handlers/__tests__/updaterError.test.ts
The updater checks for 1 GB of free space, formats disk-space and incomplete-download errors, applies the checks to downloads and errors, and tests the formatting helpers.
Installation result and shutdown lifecycle
apps/desktop/src/main/handlers/updateHandlers.ts, apps/desktop/src/preload/api/updates.ts, apps/desktop/src/main/index.ts
Installation now returns { ok: boolean; error?: string }, schedules quitAndInstall, tracks installation state, and bypasses normal shutdown work during installation.
Renderer update outcome handling
apps/desktop/src/renderer/components/UpdateBanner.tsx, apps/desktop/src/renderer/pages/settings/sections/UpdatesSection.tsx
The update UI displays returned download and installation errors and handles rejected installation calls.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 959e3

Update installation failures can still leave the application in an incomplete state: users may see a download error and retry the wrong operation, while an interrupted installer can suppress normal shutdown cleanup and permit repeated attempts. The PR should address these bounded failure-path risks before merge.

- Around line 102-104: Update the installNow failure handling in UpdateBanner so
it preserves an installation-specific error state and renders the corresponding
installation failure message and retry action. Ensure the Retry control invokes
the installation flow rather than handleDownload, while leaving download
failures on their existing path.

A disk-full install used the generic error state, which said Download
failed and retried the download. Install errors now retry Restart to Update.
