23:13 | Merge all recent trunk changes, including the movement of the pragma table into the separate pragma.h header file. (Closed-Leaf check-in: 3af19f8444 user: drh tags: index_xinfo) | |
2015-01-31
| ||
02:34 | Merge in support for the index_xinfo pragma. (check-in: f9b6dc7702 user: drh tags: ota-update) | |
02:00 | Add the "index_xinfo" pragma. Add new columns to the "index_info" and "index_list" pragmas. (check-in: 30f51d7b3b user: drh tags: index_xinfo) | |
2015-01-30
| ||
20:59 | Change SQLITE_TESTCTRL_INITMODE to SQLITE_TESTCTRL_IMPOSTER. Revise the order of parameters. Give it the ability to reset the schema parse table so that imposter tables can be erased. (check-in: 42d5601739 user: drh tags: trunk) | |
