32 check-ins using file src/btree.c version 8ac6ae35

2017-06-07
19:46
Fix another lsmtest build problem. Add the "-trans BOOLEAN" option to "lsmtest speed2". check-in: 61853bc1 user: dan tags: lsm-vtab
16:25
Merge in trunk enhancements. check-in: f8bbb608 user: drh tags: prepare_v3
10:55
Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk. Some TCL tests fail on this check-in due to the new stat1 entries. Leaf check-in: c81f260c user: drh tags: analyze-empty-tables
