| 23:01 | [38ad90cab8] part of check-in [31942b3dd3] Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined.
