| 16:04 | • Fixed ticket [e63b4d1a]: Query on rtree unexpectedly yields 0 rather than 0.0 plus 5 other changes (artifact: 7861527d user: drh) | |
| 16:04 | The RTREE extension behaves as if data columns have type REAL, so we should actually declare them as REAL so that automatic indexes handle them correctly. Ticket [e63b4d1a65546532] (check-in: 85a9b6a9 user: drh tags: trunk) | |
| 14:49 | • New ticket [e63b4d1a] Query on rtree unexpectedly yields 0 rather than 0.0. (artifact: 5e3591cf user: mrigger) | |

| ||
| 17:16 | In sqlite3changeset_apply(), ensure that DELETE and UPDATE changes are always executed on main database tables, not similarly named temp tables, as documented. INSERT statements are already being handled correctly. (check-in: f71a13d0 user: dan tags: trunk) | |
| 16:21 | Fix harmless compiler warnings from MSVC. (check-in: 951b39ca user: drh tags: trunk) | |
| 15:20 | Merge latest trunk changes into this branch. (check-in: 3f5650aa user: dan tags: reuse-schema) | |
| 15:07 | Optimization for "SELECT min(x) FROM tbl" where "x" is indexed and NOT NULL. This also allows similar queries on NOT NULL virtual table columns to be optimized. (check-in: 59726777 user: dan tags: trunk) | |
| 13:54 | Extra zero terminators on the end of the blank filename returned by sqlite3PagerFilename() for an in-memory database. This helps the result work better with sqlite3_filename_journal() and similar functions. (check-in: 63e533d2 user: drh tags: trunk) | |
| 12:33 | Backport the change that allows the filename passed into the xFullPathname to be used as an argument to sqlite3_uri_parameter(). (check-in: 9c77bfe4 user: drh tags: branch-3.31) | |
| 11:32 | Ensure that the filename passed into the xFullPathname method of the VFS is acceptable as an argument to sqlite3_uri_parameter(). The interface spec does not guarantee this, but it has been so historically and some applications have come to depends on it. (check-in: bfb09371 user: drh tags: trunk) | |
|
2020-02-25
| ||
| 20:05 | Update the fuzzcheck test module so that it avoids inserting text values that contain embedded NULs in the XSQL table. Fix some legacy entries in the test/fuzzdata8.db that had embedded NULs. Add in new dbsqlfuzz cases that have accumulated over on the dbsqlfuzz project for a while. (check-in: 47d4240c user: drh tags: trunk) | |
|
2020-02-24
| ||
| 17:05 | If STAT4 determines that a WHERE clause term that is not used by an index has very high probability of being true, then do not use that term to reduce the estimated output row count. (check-in: 40739c79 user: drh tags: trunk) | |
| 16:46 | Rework this changes so that instead of setting the WhereTerm.truthProb when a term is seen to be of low selectivity, it merely sets a new flag (the TERM_HIGHTRUTH flag) which causes whereLoopOutputAdjust() to ignore that term. (Closed-Leaf check-in: 4558163b user: drh tags: stat4-truthprob) | |
| 13:35 | Disable the new analyzeG.test module if not building with STAT4. (check-in: 4a9d3005 user: drh tags: stat4-truthprob) | |

| ||
| 18:27 | Do not activate the truthProb adjustment mechanism if the truth probability is less than the heuristic value, as there could be correlations unknown to stat4. Also add additional tracing output to make truthProb adjustments more visible. (check-in: c535fea1 user: drh tags: stat4-truthprob) | |
| 17:32 | Add new test file analyzeG.test, containing a test for the change on this branch. (check-in: 243ab185 user: dan tags: stat4-truthprob) | |
| 16:58 | When stat4 information is available, try to use it to improve the truth probability of WHERE clause terms that do not participate in the index. (check-in: 1babd6ec user: drh tags: stat4-truthprob) | |
| 13:07 | • Fixed ticket [aa437869]: sqlite3.c:87338: int sqlite3VdbeExec(Vdbe *): Assertion `sqlite3BtreeCursorIsValid(pCrsr)' failed. plus 6 other changes (artifact: 9fee2067 user: drh) | |
| 13:01 | In the OP_Column opcode, if the cursor is marked NullRow (due to being the right table of a LEFT JOIN that does not match) and the cursor is the table cursor for an OR-optimization with a covering index, then do not substitute the covering index cursor, since the covering index cursor does not have the NullRow flag set. Ticket [aa4378693018aa99] (check-in: f02030b3 user: drh tags: trunk) | |
| 04:18 | • New ticket [aa437869] sqlite3.c:87338: int sqlite3VdbeExec(Vdbe *): Assertion `sqlite3BtreeCursorIsValid(pCrsr)' failed.. (artifact: ba0b33c0 user: yongheng) | |
