Alex Hall	fa6b57855e	(core) Cache converting timestamp to date ... Summary: Adds `@functools.lru_cache` to `ts_to_dt` and `ts_to_date` which are used in `_make_rich_value` in Date/DateTime columns, i.e. every time such a column is accessed in a formula. I noticed that these operations are surprisingly expensive while working on https://phab.getgrist.com/D4075. This is just an easy way to potentially significantly speed up certain docs and formulas. Test Plan: Put this code in an engine test case: ``` def test_(self): self.apply_user_action(["AddTable", "Table1", [ {"id": "A", "type": "DateTime:America/Chicago"}, ]]) self.add_records("Table1", ["A"], [ [i] for i in range(1000) ]) formula = "for _ in range(1000): $A\nreturn 1" import time start = time.time() self.add_column( "Table1", formula, type="Any", isFormula=True, formula=formula ) elapsed = time.time() - start print(f"Took {elapsed:.2f} for formula {formula}") ``` The time goes from ~10s to ~1s. Similar tests showed no noticeable slowdown when caching had no effect. Reviewers: dsagal Reviewed By: dsagal Differential Revision: https://phab.getgrist.com/D4099	9 months ago
Alex Hall	5d671bf0b3	(core) New type conversion in the backend ... Summary: This is https://phab.getgrist.com/D3205 plus some changes (https://github.com/dsagal/grist/compare/type-convert...type-convert-server?expand=1) that move the conversion process to the backend. A new user action ConvertFromColumn uses `call_external` so that the data engine can delegate back to ActiveDoc. Code for creating formatters and parsers is significantly refactored so that most of the logic is in `common` and can be used in different ways. Test Plan: The original diff adds plenty of tests.
