added: export import notebook to include connection - #425
Conversation
📝 WalkthroughWalkthroughThe PR adds connection-aware notebook export and import flows, including import-file previews and optional credential transfer. It also serializes notebook writes per file to prevent concurrent read-modify-write conflicts. ChangesNotebook transfer and persistence
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Notebook import and export can leave partial connections, omit recent edits, or overwrite concurrent changes; oversized previews can also exhaust application memory. These issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Reject oversized files before fs.readFile.
The size check runs only after fs.readFile allocates the complete file. A user can select a multi-gigabyte file, which can exhaust main-process memory before this method rejects it. Check the file size before reading its contents.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Flush pending cell saves before both export reads.
NotebookEditor delays useUpdateNotebook().mutate for 500 ms. Both getNotebook and listNotebooks read notebook files from disk, so an export started during this delay can omit the latest in-memory cell content. Expose one async flush barrier for the active NotebookEditor, await the completed mutateAsync save, and use it in both handleExportConfirm and handleExportAllNotebooksConfirm.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift
Rollback the saved connection and its credentials when credential storage fails.
saveConnection persists finalConnection before storeImportedConnectionCredentials performs sequential secure-storage writes. If a write fails, notebook import stops and a retry selects an (Imported) name. connectorsServices.deleteConnection(id) alone is insufficient because its cleanup uses the connection ID, while these credentials use the connection name. Delete the partially written name-based credentials and the saved connection together, or provide a main-process operation that performs both atomically.
