Add code to actually use the sqlite_stat2.cnt field in the query planner. This changes some plans resulting in a few failures in analyze5.test. Closed-Leaf check-in: d1248165e3 user: drh tags: query-planner-tweaks

The ANALYZE command adds the sqlite_stat2.cnt column if it does not already exist. check-in: 794fde6f91 user: drh tags: query-planner-tweaks

The sqlite_stat2.cnt field is parsed if it is present. But it is not yet used. A large comment added to analyze.c to explain the format of the ANALYZE system tables. check-in: 6d1e2372fe user: drh tags: query-planner-tweaks

Merge together the fork in the query-planner-tweaks branch. check-in: 2daab6bd42 user: drh tags: query-planner-tweaks

Fix a compiler warning when STAT2 is off. More test cases. Fix legacy tests to deal with the new STAT2 logic. check-in: 7e914aa999 user: drh tags: query-planner-tweaks

Bug fixes to the sample-count logic for STAT2. A few test cases added. check-in: e93c248c84 user: drh tags: query-planner-tweaks

Add a column to the sqlite_stat2 table that contains the number of entries with exactly the same key as the sample. We do not yet do anything with this extra value. Some tests in analyze2.test are failing. check-in: eb43422827 user: drh tags: query-planner-tweaks
01:09
Allow the sqlite_stat2 table to contain a number of samples other than the default of 10. check-in: b9d41c3490 user: drh tags: query-planner-tweaks

Merge the winopen-retry-logic branch into trunk. The biggest change here is to test scripts, which should now use such as copy_file and delete_file from tester.tcl rather than the raw file commands of TCL. check-in: b90c28be38 user: drh tags: trunk

Adjust the output row estimating logic when using STAT2. check-in: c8ba8855d8 user: drh tags: query-planner-tweaks
