2018-10-30
| ||
| 16:25 | Split the SQLITE_WriteSchema flag in two flags, WriteSchema and SQLITE_NoSchemaError. Set only WriteSchema on a VACUUM to avoid problems when trying to vacuum a corrupt database. With this change, the size of the flags field on sqlite3 must grow from 32 to 64 bytes. file: [a1334e70] check-in: [4f987810] user: drh branch: trunk, size: 16349 | |

|
2018-10-01
| ||
| 21:26 | Change the name of the pragma to PRAGMA table_xinfo. Improve the mkpragmatab.tcl script to reuse column names where appropriate. file: [fc895d5a] check-in: [2fdd0689] user: drh branch: pragma-table-vinfo, size: 16101 | |

|
2018-09-28

|
2017-06-26
| ||
| 13:57 | Add the SQLITE_DBCONFIG_ENABLE_QPSG option to activate the query planner stability guarantee. This involves refactoring the sqlite3.flags bitvector to carve out a free bit to use. file: [aa94395a] check-in: [7076e828] user: drh branch: enable-QPSG, size: 14848 | |

|
2017-02-22
| ||
| 20:24 | Change the name of the analyze_as_needed pragma to "optimize".

| 13:38 | Enhance the Index and Table objects so that they remember if their stats come from the sqlite_stat1 table. Make the "PRAGMA stats" an SQLITE_DEBUG only pragma. Add the flags column to "PRAGMA stats".

|
2017-01-05
| ||
