fix(updates): let "Check for updates" run when an update is already staged

[arul28]

The bug

Reported from a real install: on 1.2.60 with 1.2.61 downloaded and pending restart, Settings showed Downloaded 1.2.61 · Latest 1.2.61 and pressing Check for updates did nothing — days after 1.2.62 shipped.

runUpdateCheck (autoUpdateService.ts:967) returns early when snapshot.status === "ready":

|| (!args.allowReady && snapshot.status === "ready")

That guard is correct for the startup and periodic timers — they must not disturb an update that is downloaded and waiting. But the Settings button went through the same checkForUpdates() entry point with no allowReady, so it never made a network request. No error, no state change, and the displayed "Latest" frozen at whatever the last real check found. Indistinguishable from a broken button.

The only caller that passed allowReady: true was refreshReadyUpdateBeforeInstall, which re-checks just before installing — which is why restarting to update did eventually pick up newer versions.

The fix

checkForUpdates takes { userInitiated }; the IPC handler (the button's only caller) passes it, and the timers keep standing down.

This does not restart or clobber a download. The ready branch of the check (:999) returns before the download block, so a user-initiated check refreshes latestKnownVersion and leaves the staged update intact. The card then honestly reads Downloaded 1.2.61 · Latest 1.2.63.

Tests

New regression test in autoUpdateService.test.ts: from a staged-ready state, an automatic check makes no request, a user-initiated one does, and the result reports the newer version while status/version stay on the staged update. 56 tests pass; tsc --noEmit clean.

📝 Walkthrough

Walkthrough

The update service now distinguishes automatic and user-initiated checks when an update is staged. Settings-triggered checks pass the user-initiated flag, and regression coverage verifies metadata refresh without replacing the staged update.

Update check behavior

Layer / File(s)	Summary
Ready-update check handling apps/desktop/src/main/services/updates/autoUpdateService.ts, apps/desktop/src/main/services/updates/autoUpdateService.test.ts	checkForUpdates accepts a user-initiated option and allows manual checks to refresh metadata while preserving the staged update. Automatic checks retain the early return.
Settings check wiring apps/desktop/src/main/services/ipc/registerIpc.ts	The Settings-triggered IPC handler passes userInitiated: true to checkForUpdates.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 9cec3

A manual update check can replace an already downloaded update instead of preserving it, potentially changing which version is installed after restart. Merge should wait until the refresh preserves the staged update and avoids starting a new download.

🧩 Analysis chain

🌐 Web query:

For electron-updater 6.8.3, when autoDownload is false and checkForUpdates finds a newer version, can it emit update-available before checkForUpdates resolves?

💡 Result:

Yes, in electron-updater 6.8.3, the update-available event is emitted before the promise returned by checkForUpdates resolves [1]. When you call checkForUpdates, the internal implementation executes the update check process. Once it determines that an update is available, it calls its internal onUpdateAvailable method, which explicitly emits the update-available event [1]. Only after this emission (and other associated logic) does the function return the UpdateCheckResult object, which resolves the promise [1]. Therefore, your event listener for update-available will trigger before the code awaiting checkForUpdates resumes execution [1].

Preserve the staged update during a manual check.

When autoDownload is false, electron-updater emits update-available before checkForUpdates() resolves. The newer event changes ready to checking. The resolved check then calls downloadUpdate() and can replace staged version 1.2.61 with 1.2.63.

• Add a metadata-only ready-refresh mode in autoUpdateService.ts. Preserve the staged version and skip download handling for newer update-available events.
• Update the named regression test to emit checking-for-update and update-available for 1.2.63. Assert that 1.2.61 remains staged and downloadUpdate is not called.
