error finding workspace for tab to delete %s: %w

Error message

error finding workspace for tab to delete %s: %w

What it means

When recursive=true and the block's parent tab becomes empty, DeleteBlock tries to close the tab too. It first resolves the owning workspace with DBFindWorkspaceForTabId; if that lookup fails it wraps it as "error finding workspace for tab to delete %s: %w". The tab cascade cannot proceed without the workspace id needed by DeleteTab.

Solutions

1. Inspect the wrapped cause; if it is a DB error, fix the store/IO issue first.
2. Verify the tab actually belongs to a workspace (check its ParentORef); delete orphaned tabs manually.
3. Skip the recursive cascade (recursive=false) and delete the empty tab through a separate code path once the workspace mapping is repaired.
4. Rebuild workspace-tab relationships from block/tab ParentORef data if the index is inconsistent.

Example fix

// before
wcore.DeleteBlock(ctx, blockId, true) // fails when tab's workspace row is gone
// after
wsId, err := wstore.DBFindWorkspaceForTabId(ctx, tabId)
if err != nil {
    // repair or skip tab cascade
    return wcore.DeleteBlock(ctx, blockId, false)
}
wcore.DeleteBlock(ctx, blockId, true)

wsId, err := wstore.DBFindWorkspaceForTabId(ctx, tabId)
if err != nil {
    // fall back to non-recursive delete
    return wcore.DeleteBlock(ctx, blockId, false)
}

if err := wcore.DeleteBlock(ctx, blockId, true); err != nil && strings.Contains(err.Error(), "error finding workspace for tab") {
    // degrade gracefully: block deletion matters more than tab cleanup
    log.Printf("skipping tab cascade: %v", err)
}

When it happens

Trigger: Recursive delete of the last block in a tab, but DBFindWorkspaceForTabId returns an error — the tab's workspace linkage is missing from the store or the DB query itself fails.

Common situations: Orphaned tab rows after a partial workspace deletion or corrupted store; DB read error during the workspace->tab join lookup.
