Rollback logic is unreachable—forceSyncToBackend never throws.
forceSyncToBackend calls syncToBackend() which catches all errors internally (line 222–226) without re-throwing. Both functions always resolve successfully, making the catch block at lines 316–322 dead code.
Impact:
- When backend sync fails, the optimistic UI update persists (subscription appears removed).
- The user sees the success alert on line 324 even though sync failed.
- No rollback occurs, leaving local and backend state inconsistent.
To fix this, forceSyncToBackend must either propagate errors or return a success/failure indicator.
🛠️ Possible fix: Return sync result from forceSyncToBackend
Option 1: Modify forceSyncToBackend to return a boolean:
// In autoSync.ts
export async function forceSyncToBackend(): Promise<boolean> {
if (_debounceTimer) {
clearTimeout(_debounceTimer);
_debounceTimer = null;
}
_hasPendingLocalChanges = true;
return await syncToBackendWithResult();
}
async function syncToBackendWithResult(): Promise<boolean> {
// ... existing syncToBackend logic ...
try {
// ... sync ...
return failures.length === 0;
} catch (err) {
console.error('Failed to sync to backend:', err);
return false;
}
}Option 2: Check sync result in component:
- try {
- await forceSyncToBackend();
- } catch (error) {
- console.error('Failed to unsubscribe release:', error);
+ const syncSuccess = await forceSyncToBackend();
+ if (!syncSuccess) {
+ console.error('Failed to unsubscribe release');
updateRepository({ ...repo, subscribed_to_releases: true });
toggleReleaseSubscription(repo.id);
alert(t('取消订阅失败，请检查后端连接。', 'Failed to unsubscribe. Please check backend connection.'));
return;
