| 14:19 | Add a test case to check that the previous commit is effective. check-in: 948d6e5d user: dan tags: trunk | |
| 13:13 | Enhance whereLoopCheaperProperSubset(X,Y) so that it does not report true if X uses skip-scan less than Y, since in that case X might deserve to be cheaper even if it is a proper subset. check-in: c106b755 user: drh tags: trunk | |
| 09:07 | Add the ".scanstats on" command to the shell tool. Executing this command causes the shell tool to print values from sqlite3_stmt_scanstatus() after each query is run. check-in: 7974c0ed user: dan tags: trunk | |

Also, document the fact that setting scratch memory causes SQLite to try to avoid large memory allocations. check-in: a518bc33 user: drh tags: trunk | |
| 13:24 | When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to record the entire size of the allocation, not just the requested size. check-in: 3dda3c93 user: drh tags: trunk | |
| 11:25 | Remove unused variable from struct WhereInfo. Add some explanatory comments to new code. check-in: f5313e0c user: dan tags: scanstatus | |

Fix for ticket [43107840f1c02]. check-in: 24780f8d user: drh tags: trunk | |
