From ab9c5a01b0a62ad97b47ca02caf6bad8eb8f5a42 Mon Sep 17 00:00:00 2001 From: Robert Klink Date: Wed, 31 Jul 2024 14:38:25 +0200 Subject: [PATCH] unix-ffi/sqlite3: Add optional parameter for URI support. This commit adds the ability to enable URI on the connect, as can be done in the cpython sqlite3 module. URI allows, among other things, to create a shared named in-memory database, which non URI filenames cannot create.
