| 14:48 | Remove the "#ifdef SQLITE_TEST" condition from fts5_test_mi.c. Update fts5_main.c so that if SQLITE_FTS5_TEST_MI is defined when it is built the fts5_test_mi.c entry point is automatically called. This makes it easier to build versions of fts5 that include the matchinfo() demo by default. check-in: 87e6e225 user: dan tags: trunk | |
