Commit Message

chris.laplante@agilent.com Nov. 25, 2024, 5:22 p.m. UTC 
From: Chris Laplante <chris.laplante@agilent.com>

Python 3.13 emits a ResourceWarning for unclosed sqlite3 `Connection`s.
See https://docs.python.org/3/whatsnew/3.13.html#sqlite3

The previous commit fixed persist_data's context manager to close the
connection, but we were never actually using `with` in the first place.

This change is not necessary on 'master' because persist_data was
removed.

Signed-off-by: Chris Laplante <chris.laplante@agilent.com>
(cherry picked from commit 61f803c7d92a012b62837b0cdae4789a394b260e)
