| 00:29 | In the push-down optimization, do not substitute columns that have previously been identified as being constant by the propagate-constants optimization. Fix for ticket [51166be0159fd2ce]. Also, avoid factoring out constant expressions on the LHS of an IN(...) operator, as the IN(...) operation may affect the affinity of these values. Fix for [fd1bda016d1]. (Leaf check-in: 43612157 user: drh tags: branch-3.31) | |

| 13:39 | Do not suppress errors when resolving references in an ORDER BY clause belonging to a compound SELECT within a view or trigger within ALTER TABLE. Fix for ticket [a10a14e9b4ba2]. Also, in the event of a semantic error in an aggregate query, early-out the resetAccumulator() function to prevent problems due to incomplete or incorrect initialization of the AggInfo object. Fix for ticket [af4556bb5c285c08]. (check-in: b6467491 user: drh tags: branch-3.31) | |
| 13:29 | Fix a case when a pointer might be used after being freed in the ALTER TABLE code. Fix for [4722bdab08cb1]. (check-in: 52f800fa user: drh tags: branch-3.31) | |

| 19:23 | Prevent the read-only expressions held in the schema from being passed down into code generating subroutines where they might be changed. Pass a copy of the expression instead. (check-in: 2b750b0f user: drh tags: branch-3.31) | |
| 18:55 | Further changes to ensure that expressions held in table and index definitions do not get passed down into code generator logic where they might be modified. (check-in: f45f5de0 user: drh tags: trunk) | |
| 13:35 | Make a copy of the expression that defines a value of a generated column before sending it to the code generator routines. (check-in: 03d201c0 user: drh tags: trunk) | |
| 11:50 | Apply the correct affinity transformations when pulling values off of the sorter index used for GROUP BY. Ticket [e0c2ad1aa8a9c691] (check-in: 101f7dea user: drh tags: trunk) | |
| 02:57 | The sqlite3ExprCodeFactorable() routine should make a copy of non-factorable expressions, as they might be coming from a DEFAULT or generated column in a table constraint. (check-in: a2d6f108 user: drh tags: trunk) | |
| 01:24 | Background work for experiments trying to enhance ANALYZE so that it runs off of samples of the entire index and does not need to read the entire index. (check-in: 29d1cc5c user: drh tags: approximate-analyze) | |
|
2020-03-09

| 18:04 | Report an error if the main, or any other, database encoding is modified by an external process (perhaps using the backup API) after the db has been opened. (check-in: 895bd20b user: dan tags: trunk) | |
| 16:13 | Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc]. (check-in: 4a585189 user: drh tags: trunk) | |
| 14:19 | When printing the OP_CollSeq opcode for EXPLAIN listings, include the text encoding with the name of the collating sequence. (check-in: eb5c1b77 user: drh tags: trunk) | |

|
2020-02-29
| ||
| 17:19 | Fix a problem with window functions occuring within sub-selects that are part of an OR term in a WHERE clause of the outer SELECT. (check-in: 1e174ed0 user: dan tags: trunk) | |
| 15:53 | In the CLI, add the ".oom" command for debugging builds. (check-in: 9c3136a7 user: drh tags: trunk) | |
|
2020-02-28
| ||
| 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) | |
|
2020-02-27
| ||
| 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) | |
| 15:07 | 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) | |

| 17:34 | Fix a problem with ALTER TABLE for views that have a nested FROM clause. Ticket [f50af3e8a565776b]. (check-in: c431b3fd user: drh tags: trunk) | |
|
2020-02-22
| ||
| 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) | |
| 13:01 | 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) | |
|
2020-02-20

|
2020-02-17
| ||
| 23:08 | Convert invalid surrogates to 0xfffd when translating UTF. (check-in: 7fab1393 user: drh tags: trunk) | |
| 19:25 | A better (smaller and faster) solution to ticket [4374860b29383380]. (check-in: abc473fb user: drh tags: trunk) | |
| 00:12 | Take care when checking the table of a TK_COLUMN expression node to see if the table is a virtual table to first ensure that the Expr.y.pTab pointer is not null due to generated column optimizations. Ticket [4374860b29383380]. (check-in: 9d0d4ab9 user: drh tags: trunk) | |
|
2020-02-16

| 13:45 | Omit O_NOFOLLOW from the open() call when opening /dev/null, since /dev/null is a symlink on Solaris, we are told. (check-in: 0c683c43 user: drh tags: trunk) | |
| 11:46 | Fix an incorrect assert() statement that was added yesterday. Tickets [41c1456a6e61c0e7] and [fb8c538a8f57ae2a]. (check-in: abfb043e user: drh tags: trunk) | |
|
2020-02-12

| 20:50 | Increase the default upper bound on the number of parameters in a single SQL statement to 32766 (from 999). (check-in: 2def7569 user: drh tags: trunk) | |
| 11:57 | When determining whether an == or IS constraint in a WHERE clause makes an ORDER BY term redundant, consider the collation sequence used by the == or IS comparison, not the collation sequence of the comparison expression itself. Possible fix for [fb8c538a8f]. (check-in: 16aed5d0 user: dan tags: trunk) | |
