| 16:53 | Add a test case for detaching a database referenced by an fts4aux table created in the temp schema. (check-in: 6d6f0592 user: dan tags: trunk) | |
| 16:47 | Change the fts4aux virtual table module so that fts4aux tables created in the temp database may report on fts3/fts4 tables in any attached database. (check-in: 546a187f user: dan tags: trunk) | |
| 01:04 | In mptester: improve the way that child processes are dispatched. Pass the --vfs option through to children. Log the command used to start child processes when the tracing level is high enough. (check-in: 55718ae3 user: drh tags: trunk) | |
