|14:37||Improve the accuracy of the estimates used when searching an index for values not present in any stat4 samples. check-in: 3aff9a9cac user: dan tags: trunk|
|10:22||Add a test to show that the change on this branch is effective. Closed-Leaf check-in: fc619be057 user: dan tags: stat4-avgeq|
|00:07||Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside. check-in: efd87ba142 user: drh tags: stat4-avgeq|
|19:29||Fix a division-by-zero error that might occur if the sqlite_stat1 table is corrupt. check-in: f9c053b23e user: dan tags: stat4-avgeq|
|19:16||Improve the accuracy of the estimates used when searching an index for values not present in any stat4 samples under some circumstances. check-in: e6f7f97dbc user: dan tags: stat4-avgeq|
|16:00||Add requirements marks on the sqlite3_db_status() interface implementation. Fix a typo in the documentation. Fix the new sqlite3_result_text64() routine so that it works correctly with an encoding parameter of SQLITE_UTF16. check-in: d2fc322728 user: drh tags: trunk|
