|
2020-03-05
| ||
| 19:00 | Merge trunk change [895bd20b29] into this branch. (Actually check-in date was 2020-05-18) (check-in: 507f972e user: dan tags: reuse-schema) | |
| 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) | |
| 16:30 | Merge trunk enhancements into the reuse-schema branch. (Actual check-in date is 2020-05-18) (check-in: 9d068e1e user: drh tags: reuse-schema) | |
| 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) | |
|
2020-03-03
| ||
| 20:48 | Fix a false-positive in the debugging logic that attempts to detect the use of uninitialized registers inside triggers. Ticket [c4c56482ced89d90] (check-in: 0463576b user: drh tags: trunk) | |
| 20:04 | Remove an invalid assert() on the debugging logic that checks to ensure that register values are not used after they go stale. Ticket [d165ad781b39d574]. (check-in: bd94d7d0 user: drh tags: trunk) | |
| 01:16 | Improved detection of corruption in the interior nodes of a segment btree in FTS3/4. (check-in: cc99447a user: drh tags: trunk) | |

2020-03-02
| ||
| 16:31 | Enhance the fuzzcheck test program so that it is able to simulate OOM errors in the same way that dbsqlfuzz does. (check-in: a65c8d4e user: drh tags: trunk) | |
| 01:50 | Fix a faulty assert() statement in the stale-register detection logic. Ticket [da5a09be6dabbf42]. (check-in: 219c296c user: drh tags: trunk) | |
| 01:16 | Ensure that the NULL-scan pass counter is initialized when a ORDER BY NULLS LAST is used on the right table of a LEFT JOIN. Ticket [e12a0ae526bb51c7]. (check-in: 704bb9a3 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) | |
| 15:20 | 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) | |
| 13:26 | Merge bugfix from trunk. (check-in: b542dee9 user: drh tags: stat4-truthprob) | |
|

|
2020-02-22
| ||
| 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
| ||

| 14:08 | Early-out on the INTERSECT query processing following an out-of-memory error. This fixes a potential null pointer dereference found by sakura(@eternalsakura13) of Alpha Team, Qihoo 360. (check-in: a67cf5b7 user: drh tags: trunk) | |
|
2020-02-19

|
2020-02-18
| ||
| 23:58 | Remove a NEVER() macro and add a test case to cause its argument to be true. (check-in: ee034fe9 user: drh tags: trunk) | |
| 19:49 | Add the new sqlite3_create_filename() and sqlite3_free_filename() interfaces for use by Shims. Use these interfaces inside the multiplexor. (check-in: 9469f36a user: drh tags: trunk) | |
|
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
| ||
| 17:40 | Avoid an infinite recursion on an illegal recursive definition of an fts5vocab table. (check-in: 109ee074 user: drh tags: trunk) | |
|
2020-02-13
| ||

| 14:51 | Disallow the skip-scan optimization in the absence of sqlite_stat1 data. (check-in: e0c6b8bd user: drh tags: trunk) | |
| 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) | |
|
2020-02-10
| ||

|
2020-02-06
| ||
| 20:46 | There is no need to keep track of the number of changed rows or of the last-insert-rowid while running VACUUM. (check-in: a8a7c05b user: drh tags: trunk) | |

|
2020-02-03
| ||

| 14:40 | Revise the layout of filenames in the Pager object so that it is unchanged from prior versions. It turns out that some important 3rd-party software does questionable pointer manipulations on those filenames that depend on that legacy layout. Technically, this is a misuse of SQLite by the 3rd-party software, but we want to avoid unnecessary breakage. (check-in: 34ab7606 user: drh tags: trunk) | |
