fix(updates): a manual check must not discard the update already downloaded - #1135
Conversation
…loaded #1134 let the Settings button check while an update was staged, and claimed the staged download was left untouched. It was not. electron-updater emits `update-available` BEFORE checkForUpdates() resolves, so for a newer version onUpdateAvailable took the supersede branch: it cleaned the updater cache ("superseded_ready_update") — deleting the finished download — and patched the status off `ready`. The resolve path's `status === "ready"` guard then no longer held, so it started downloading the new version. Pressing "Check for updates" with 1.2.61 staged therefore threw away ~200 MB of completed download and began again, and the pending restart was lost. A user-initiated check while ready is now metadata-only: it records the newest version and returns, leaving the cache, the status and the staged version alone. The pre-install refresh and the automatic timers are unchanged. The regression test now emits the real event order (checking-for-update and update-available before resolution) instead of only resolving, and asserts downloadUpdate is never called. Verified failing without the fix, with the snapshot reaching `downloading` — the mock in #1134 could not observe this, which is why the test passed against broken behaviour.

Failed metadata check discards staged update
High Severity
A Settings check while ready is meant to be metadata-only, but a failed feed request still hits onError and the checkPromise catch. Those paths call setErrorSnapshot because they only special-case readyRefreshInProgress. With currentPhase set to download by checking-for-update, the cache is deleted and status leaves ready, so the finished download and pending restart are lost.

… alone Both review bots caught the same hole independently: the metadata-only path covered success and not failure. onError and the runUpdateCheck catch special- cased only readyRefreshInProgress, so a feed error during a user-initiated check fell through to setErrorSnapshot — replacing the `ready` snapshot with `error` and, with currentPhase already moved to "download" by `checking-for-update`, taking the finished download with it. A network blip while pressing "Check for updates" would therefore destroy a completed update: worse than the silent no-op this all started as. Both paths now return early during a metadata refresh, logging autoUpdate.metadata_refresh_failed and leaving status, version and cache untouched. The user is told nothing new, which is the honest answer when the feed did not respond. Test extended to the failure path and verified failing without the fix (snapshot reached `error`). The added settle before the second check is deliberate: while checkPromise is set the in-flight guard swallows the call and the assertion would prove nothing.

Follow-up to #1134, which I merged too fast. CodeRabbit flagged this on that PR and it was right.
The defect #1134 introduced
#1134 allowed the Settings button to check while an update was staged, and both its code comment and PR body claimed the staged download was left untouched. It was not.
