🌐 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.
