George Gevoian	62db263d1f	(core) Add diff preview to Importer ... Summary: Updates the preview table in Importer to show a diff of changes when importing into an existing table and updating existing records. Test Plan: Browser tests.

George Gevoian	e1780e4f58	(core) Migrate import code from data engine to Node ... Summary: Finishing imports now occurs in Node instead of the data engine, which makes it possible to import into on-demand tables. Merging code was also refactored and now uses a SQL query to diff source and destination tables in order to determine what to update or add. Also fixes a bug where incremental imports involving Excel files with multiple sheets would fail due to the UI not serializing merge options correctly. Test Plan: Browser tests.

George Gevoian	8a7edb6257	(core) Enable incremental imports ... Summary: The import dialog now has an option to 'Update existing records', which when checked will allow for selection of 1 or more fields to match source and destination tables on. If all fields match, then the matched record in the destination table will be merged with the incoming record from the source table. This means the incoming values will replace the destination table values, unless the incoming values are blank. Additional merge strategies are implemented in the data engine, but the import dialog only uses one of the strategies currently. The others can be exposed in the UI in the future, and tweak the behavior of how source and destination values should be merged in different contexts, such as when blank values exist. Test Plan: Python and browser tests. Reviewers: paulfitz Reviewed By: paulfitz Subscribers: alexmojaki Differential Revision: https://phab.getgrist.com/D3020	3 years ago
Paul Fitzpatrick	5ef889addd	(core) move home server into core ... Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported). Test Plan: existing tests pass Reviewers: dsagal Reviewed By: dsagal Differential Revision: https://phab.getgrist.com/D2552	4 years ago
