| 20:22 | Suppress harmless compiler warnings in union-vtab. check-in: 4d147a1e user: drh tags: trunk | |
| 20:17 | Remove an unused variable from unionvtab.c. check-in: a447fdf1 user: dan tags: trunk | |
| 20:03 | Improve the readability of the unionvtab code. check-in: 5bcf0f86 user: dan tags: trunk | |
| 19:51 | Have unionvtab support constraints on the column that corresponds to the INTEGER PRIMARY KEY field of the underlying source tables in the same way as rowid. check-in: 4a6c416f user: dan tags: trunk | |
| 18:50 | Add test cases to unionvtab.test. check-in: 6c9128e1 user: dan tags: trunk | |
| 18:19 | Add the union-vtab extension - still experimental and under active development. check-in: 948f9504 user: drh tags: trunk | |
| 17:34 | Do not use the flattening optimization for a sub-query on the RHS of a LEFT JOIN if that subquery reads data from a virtual table. Because it prevents the planner from creating an automatic index on the results of the sub-query, the flattening optimization sometimes slows things down in this case. check-in: 9dbae1df user: dan tags: trunk | |
| 17:13 | Avoid creating an automatic index on the RHS of a LEFT JOIN to optimize an IS term. Fix for [ce68383b]. check-in: d2f0b2e8 user: dan tags: trunk | |
| 14:41 | Change the default command-line shell history depth to 2000 lines. check-in: 0b69aa7e user: drh tags: trunk | |

| 21:03 | Add test cases to test/unionvtab.test. Closed-Leaf check-in: f2c4a584 user: dan tags: union-vtab | |
| 20:25 | Enhance error detection and fix other issues in unionvtab code. check-in: 9c3f1b9a user: dan tags: union-vtab | |
| 20:21 | Merge all the latest fixes and enhancements from trunk. check-in: e181225d user: drh tags: apple-osx | |
| 19:37 | Try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. This is a cherry-pick of [6df18e949d36] with bug fixes. check-in: cd6ac078 user: drh tags: branch-3.8.9 | |
| 19:25 | When checking for the WHERE-clause push-down optimization, verify that all terms of the compound inner SELECT are non-aggregate, not just the last term. Fix for ticket [f7f8c97e97597]. Closed-Leaf check-in: adc082c1 user: drh tags: push-down-backport | |
| 19:14 | Do not apply the WHERE-clause pushdown optimization to terms that originate in the ON or USING clause of a LEFT JOIN. Fix for ticket [c2a19d81652f40568c]. check-in: 52674f94 user: drh tags: push-down-backport | |
| 19:07 | For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Cherry-pick from [6df18e949d36]. Still need to backport bug fixes associated with that check-in. check-in: 043d6ce8 user: drh tags: push-down-backport | |
| 18:45 | Merge all changes from branch-3.20. Improvements to the fts5() extension interface. Work around a gcc/valgrind bug in the sqlite3_value_pointer() interface. check-in: e0aca7d2 user: drh tags: trunk | |
| 17:46 | Interchange to branches within an "if" statement in sqlite3_value_pointer() in order to work around a bug in gcc. Closed-Leaf check-in: 8a606e4a user: drh tags: branch-3.20 | |
| 15:38 | Improved the interface to the fts5() extension mechanism for enhanced security. check-in: bc78235f user: drh tags: branch-3.20 | |
| 13:37 | Merge the pointer-type enhancement from the 3.20 branch. check-in: 9e8e1c4a user: drh tags: trunk | |
| 12:41 | Comment changes clarifying details of the pointer-type parameter. No changes to code. check-in: e4579e50 user: drh tags: branch-3.20 | |
| 12:27 | Add the pointer-type parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a static string that must match (according to strcmp()) or else the pointer is passed as a NULL. This is a security measure to prevent crossing pointers between different extensions. check-in: e1196567 user: drh tags: branch-3.20 | |
| 11:39 | Improve the sqlite3_result_pointer() interface so that it cannot be faked using sqlite3_result_null() and sqlite3_result_subtype(). Closed-Leaf check-in: c13264d5 user: drh tags: pointer-types | |
| 09:30 | Use integer handles for fts3 cursors for a small performance improvement. Closed-Leaf check-in: f4f7196b user: dan tags: union-vtab, fts3-int-cursor | |
| 00:40 | Add an experimental "pointer type" parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a string that must compare equal using strcmp() or else the pointer comes through as a NULL. check-in: 211cce04 user: drh tags: pointer-types | |

| 15:42 | Include a hint in the header comment of the LSM1 makefile about how to set the LSMOPTS variable. check-in: b5e3b264 user: drh tags: trunk | |
| 15:32 | Update the Makefile for LSM1 so that the LSMOPTS can be set prior to including the Makefile, in order to add platform arguments such as -fPIC. check-in: fe319bcd user: drh tags: trunk | |
| 15:18 | Fix a typo in the header comment to the remember extension. No code changes. check-in: 604b9664 user: drh tags: trunk | |
| 15:14 | Change the name of the STMT virtual table to SQLITE_STMT. Also remove the first column of that virtual table, which was a pointer leak. check-in: 1bc4e934 user: drh tags: trunk | |

| 21:06 | Make the freelist format a separate feature from the page-level locking. Freelist format is now configure using "PRAGMA freelist_format". check-in: dcc40797 user: dan tags: server-process-edition | |
| 20:11 | Fix documentation typo. No changes to code. check-in: 9319f7b7 user: drh tags: trunk | |
| 19:11 | Update header comments on the carray() and remember() extensions to bring out the fact that the pointer arguments must be bound using sqlite3_bind_pointer(). check-in: 55f53965 user: drh tags: trunk | |
| 18:09 | Add new interfaces sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information. check-in: 72de49f2 user: drh tags: trunk | |

| 18:33 | In LSM, avoid calling the VFS xTestLock method to test for a lock that conflicts with one held by the same process. The results of such a call are considered undefined (since they are different under win32 and posix). check-in: a82a9bea user: dan tags: trunk | |
| 18:04 | Add the "--newlines" option to the ".dump" command in the shell to disable the newline escaping mechanism. check-in: bde431b1 user: drh tags: trunk | |
| 17:00 | When multiple constraints need to be evaluated for a row, do any constraints that involve correlated subqueries last. Hence, the priority is index-covered constraints first, correlated subquery constraints last, and all others in the middle. This is a follow-on and improvement to the push-down optimization of check-in [d7bb79ed]. check-in: c4cb9048 user: drh tags: trunk | |
