v0.8.1-dev to master#183
Conversation
WalkthroughThe changes update two components. In the database module, the identity order management now enforces referential integrity by adding a cascading delete foreign key and cleaning up orphaned identifiers during loading. In the UI module, the reordering logic has been refined by introducing a HashSet for efficient filtering of IDs, ensuring only valid identities are processed and preventing out-of-bound index errors.

338-345: Graceful handling of parse failures.
By pushing unparseable ID bytes toto_remove, the code avoids errors downstream. Consider logging a warning for easier debugging if parse failures become frequent.

288-289: Ensures proper referential integrity with cascading deletes.
By defining a FOREIGN KEY withON DELETE CASCADE, orphaned rows will be automatically removed when the referenced identity is deleted. This is a healthy step for data consistency.
320-321: Doc comment accurately reflects the revised logic.
Confirmation that identities not found in the main identity table are removed is well-expressed here.
323-323: No issue with the table existence check.
Callingensure_identity_order_table_exists()at the start prevents SQL errors.
329-329: Ordering by pos is appropriate.
Selecting identity rows by ascending position is correct for preserving the intended user order.
332-333: Separation of valid and invalid IDs is clear.
Usingfinal_listfor valid entries andto_removefor invalid entries is straightforward and maintainable.
347-369: Robust cleanup of dangling references.
The logic checks for the identity’s presence in the main table before finalizing the list. Unmatched IDs are queued and removed in one step, preventing stale data. You might optionally log how many references were cleaned to facilitate monitoring.src/ui/identities/identities_screen.rs (6)
33-33: Introduction ofHashSetis a straightforward improvement for membership checks.
This data structure choice helps keep the code concise and performant for reordering operations.
104-105: Doc comments neatly summarize the reordering changes.
They clarify that any IDs not in the provided list remain where they are, ensuring partial reordering is supported.
108-110: Early return for empty sets avoids unnecessary computation.
Guarding against empty inputs helps prevent edge-case errors or wasted cycles.
112-114: Efficient extraction of existing identifiers.
Collecting the current IDs into aHashSetallows quick membership checks, particularly valuable if the list is large.
115-121: Filtered list construction ensures valid ordering.
Discarding any unknown or extraneous IDs is a sound approach, preventing index errors and preserving consistency.
123-136: Index swapping logic is concise and well-bounded.
By checking for out-of-range indices and skipping missing IDs, you avoid panics or invalid manipulations. Good reordering safeguard.

Includes a fix for an issue that was causing some apps to panic on startup. If a user had moved their identities around in the identities screen (they were using a custom order) and then removed an identity, the identity would be removed from identity table in database but not identity_order, and it would cause a panic when loading the order.
To fix, we do 3 things:
