FlameRobin 26.8.5 Release Notes

FlameRobin v26.8.5 delivers essential bug fixes and stability improvements for Data Grid multi-batch sorting on partial result sets, modal dialog dismissal and layout lifecycle handling in the Database Maintenance & Health Dashboard, and live in-place Database Properties settings modifications without connection teardown or application crashes.

Highlights & Key Improvements

1. Data Grid Sorting on Partially Fetched Result Sets Fix (#689)

• Dynamic Row Mapping Rebuilding: Automatically rebuilds and updates rowMappingM dynamically whenever new batches or individual rows are fetched while column sorting or real-time filtering is active.
• wxGrid Row Count Synchronization: Added notifyViewRowsChanged() to post wxGRIDTABLE_NOTIFY_ROWS_APPENDED and wxGRIDTABLE_NOTIFY_ROWS_DELETED table messages, preventing newly fetched rows from rendering empty/blank cells.
• On-Demand Fetch Boundary Trigger: Fixed the scrolling proximity detection in DataGridTable::GetValue() to test the visual UI view row position (unsigned)row + 20 >= (unsigned)GetNumberRows() instead of the underlying buffer index, ensuring scrolling seamlessly triggers further data retrieval regardless of active sort order.
• Automated Unit Tests: Added regression test suite data_grid_sort_partial_fetch_test verifying multi-batch ascending/descending sorts with NULLs, combined filter+sort additions, and scroll boundary triggers.

2. Database Maintenance & Health Dashboard Dialog Dismissal Fix (#690)

• Modal Loop Termination: Updated BaseDialog::OnCloseButtonClick and BaseDialog::OnClose to call EndModal(wxID_CANCEL) when IsModal() is true, terminating the wxWidgets modal event loop cleanly.
• Proper Control Layout & Parenting: Rooted all dialog controls in BaseDialog::getControlsPanel(), formatted with styleguide().createButtonSizer() and layoutSizers().
• Standard Key & Button Handling: Mapped the dialog close button to wxID_CANCEL so clicking Close, pressing Escape, or clicking the window titlebar X button closes the window immediately without requiring Task Manager.

3. Database Properties Settings Modification Fatal Crash Fix (#686)

• Eliminated Connection Teardown in URI Handler: Removed d->disconnect() and d->reconnect() inside DatabaseInfoHandler. Modifying database header parameters (Forced Writes, Reserve Space, Read-Only, Sweep Interval, Page Buffers) via the Services API does not require client disconnection.
• Prevented Frame Destruction & Use-After-Free: Prevented Database::setDisconnected() from firing observers that triggered getParentFrame()->Close(), avoiding deletion of the calling wxHtmlWindow while the click event handler was actively running on the call stack.
• Live In-Place HTML Re-rendering: Directly reload database header properties via d->loadInfo(), refreshing the Database Properties panel in real-time.
