| 21:41 | • New ticket [82ac75ba00] Incorrect result for query with 0 >= t0.c0 AND t0.c0 = v0.c0 condition. (artifact: f92e43ead6 user: mrigger) | |
| 19:45 | Create the "trusted_schema" pragma. Add sqlite3_vtab_config() calls to set the risk rank for many virtual tables. (check-in: 4c21373c21 user: drh tags: new-security-options) | |
| 18:10 | Enforce SQLITE_VTABRISK restrictions. (check-in: 3d87ff312e user: drh tags: new-security-options) | |
| 18:10 | Fix a performance regression caused by the previous check-in. (check-in: d7d98d3dff user: drh tags: trunk) | |
| 16:09 | Invert the UNTRUSTED_SCHEMA setting to be TRUSTED_SCHEMA. (check-in: f5fcf1fbc6 user: drh tags: new-security-options) | |
| 15:44 | Merge recent fixes from trunk. (check-in: 5dfa33a09e user: drh tags: new-security-options) | |
| 14:51 | Provide the ability to tag an application-defined function as "testonly". (Leaf check-in: e6f5c0e0ac user: drh tags: testonly-functions) | |
| 13:32 | Add an "|| CORRUPT_DB" term to an assert() statement inside of btree. (check-in: 03c1d75ddc user: drh tags: trunk) | |
| 09:06 | Fix an instance of an undefined behaviour (a left-shift of a 64-bit unsigned integer by a value greater than 64) that could occur in fts3. (check-in: e1f12978b5 user: dan tags: trunk) | |

| 16:52 | Fix another potential buffer overread in fts5. (check-in: d0e943d957 user: dan tags: trunk) | |
| 15:57 | For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign key constraints that causes SQLite to clobber any existing row without separately checking for it. This optimization causes SQLite to omit the expected pre-update-hook callbacks. (check-in: 6281ef974c user: dan tags: trunk) | |

| 23:28 | Avoid the use of utimensat() on older unix platforms. (check-in: 90cb01d8d6 user: drh tags: trunk) | |
| 21:58 | Remove the dependency on test_windirent.h from the generated shell.c file. (check-in: 0a50c9e3bb user: drh tags: trunk) | |
| 20:38 | Modify the sqltclsh startup script to look for a properly formatted SQLAR at the end of the executable. Fix the CLI so that it automatically links against appendvfs and so that the --append command-line option works. (check-in: 67c4a8c688 user: drh tags: trunk) | |
| 19:52 | Improved comments on the sqlar.c and compress.c extensions that describe the differences between the "zlib format" used by SQLAR, the raw deflate format used by ZIP, and the custom format used by compress.c. No changes to code. (check-in: c13415c5ca user: drh tags: trunk) | |

| 14:47 | Improvements to the iIdxNoSeek optimization of sqlite3GenerateRowDelete() so that it is automatically disabled for BEFORE triggers but works in all other cases. (check-in: 3178ec4c27 user: drh tags: trunk) | |
| 14:26 | Critical fix to the previous check-in so that it works when there are BEFORE triggers that move the cursor before the OP_Delete has a chance to be applied. (check-in: db2c0960ff user: drh tags: trunk) | |
| 03:26 | Avoid an unnecessary btree seek while deleting an index entry due to a conflict on a REPLACE operation. (check-in: f0495c5133 user: drh tags: trunk) | |
| 00:56 | Avoid duplicate b-tree searches in the duplicate row detector used to implement DISTINCT. (check-in: d577dda0a7 user: drh tags: trunk) | |
| 00:42 | This hack illustrates how to use the VDBE_PROFILE mechanism to show which bytecode operators are using resources other than time. In this case, the number of loops through the binary search code in sqlite3BtreeMovetoUnpacked() is measured, for the purpose of helping to identify unnecessary btree searches.

| 15:17 | Fix a bug in lemon in computation of which non-terminals can generate an empty string. This bug and the fix make absolutely no difference for the grammar used by SQLite, but it can make a difference when lemon is used in other grammars. (check-in: ce32775b23 user: drh tags: trunk) | |
