Add a test case to ensure that estLog() works for negative numbers. check-in: 813469d9 user: drh tags: trunk
Make sure the estLog() routine in the query planner handles negative values correctly (always returning 1). Prior to this change, estLog(-1) would return a large number which could throw off the cost computations in the query planner in obscure circumstances. check-in: 75437bee user: drh tags: trunk
Fix an obsolete comment on the whereRangeScanEst() routine. No changes to code. check-in: b16bf851 user: drh tags: trunk
