17:46
Fix a bug in the hard_heap_limit pragma so that it returns the new value of the hard_heap_limit, not the soft_heap_limit. Change SQLITE_MAX_MEMORY so that it works by setting the default hard_heap_limit value. Closed-Leaf check-in: 33fd0c3abc user: drh tags: hard-heap-limit

2019-11-08
20:13
When a virtual table reports orderByConsumed, that tells us nothing about whether or not the SQLITE_DISTINCTBY constraint is met. Fix for ticket [7e59041f9c4e5102]. Test cases in TH3. check-in: b59f94e4da user: drh tags: trunk
2019-11-07

Fix the xferCompatibleIndex() function so that it recognizes that a PRIMARY KEY index for a WITHOUT ROWID table is different from a UNIQUE constraint index on the primary key. Ticket [302027baf1374498] check-in: 34f64f11ca user: drh tags: trunk
02:32
Restore generated column loop detection logic that was incorrectly removed from the previous check-in [9e07b48934e9a972]. This fixes ticket [299b50ba812d8e54] check-in: 104a2beb57 user: drh tags: trunk
2019-11-06
22:19
Change the way generated columns are computed so that no column is computed inside branch code that might not be taken. Ticket [4fc08501f4e56692] check-in: 9e07b48934 user: drh tags: trunk
19:25
Minor simplification to the changes from check-in [36c11ad51f]. check-in: 7bc8205dd9 user: mistachkin tags: trunk
17:31
Fix the OP_DeferredSeek index-to-table column map in P4 so that it works with generated columns. Ticket [ce22a07731530118] check-in: 36c11ad51f user: drh tags: trunk
14:49
Fix the handling of NOT NULL constraint violations for generated columns in a REPLACE statement. Ticket [2399f5986134f79c] check-in: 77b1c90add user: drh tags: trunk
2019-11-04
12:49
Changes an unreachable testcase() into an assert(). check-in: 5710845b63 user: drh tags: trunk
02:05
Fix a false-postive in the sqlite3ExprImpliesNonNullRow() decision routine, that resulted in an incorrect LEFT JOIN strength reduction when the WHERE clause contained a row-value comparison. Ticket [02aa2bd02f97d0f2] check-in: ea20068e6d user: drh tags: trunk
2019-11-03
00:07
The optimization of check-in [9b2879629c34fc0a] is incorrectly reasoned. The WHERE clause of the partial index might not be true if the table of the partial index is the right table of a left join. So disable the optimization in that case. Ticket [623eff57e76d45f6] check-in: 3be19e1151 user: drh tags: trunk
2019-11-02
17:59
Fix a problem in VIEW creation that was introduced by the generated columns feature. check-in: 9c795c4d2b user: drh tags: trunk
13:45
"STORED" is not actually a keyword. The parser looks for STORED as an ordinary identifier. check-in: 167cd574d6 user: drh tags: trunk
13:32
In sqlite3GenerateIndexKey(), do not attempt to reuse column values from the previous index if the current index is a partial index as the partial index test may have changed those values. Ticket [a9efb42811fa41ee] check-in: 17e9f65814 user: drh tags: trunk
00:00
Restore the on-line ".help" for the ".explain" command in the CLI. check-in: 28b8f1036d user: drh tags: trunk
2019-11-01
18:52
Fix a harmless compiler warning. check-in: f0ebea35d9 user: drh tags: trunk
17:31
The SET DEFAULT and SET NULL conflict resolution actions for foreign key constraints should cause an error when they appear on a generated column. check-in: b47513d2b3 user: drh tags: trunk
16:37
Fix a potential use-after-free bug that follows an OOM error in code added two days ago by check-in [84e02d773d60cffe]. Problem discovered by OSSFuzz. check-in: 0a2eb949f8 user: drh tags: trunk
16:08
Add another missing column number translation to the foreign key logic. check-in: 32df5edcfe user: drh tags: trunk
15:19
Omit the optimization that reduces the column-count on rowid-table cursors when the table has generated columns, because we do not know what columns the generator expressions might try to access. check-in: e6c96ed91e user: drh tags: trunk
13:37
Fix an fts3 assert() that could fail when operating on a database containing corrupt records. check-in: 7c52f5478f user: dan tags: trunk
12:14

10:49
Fix a potential array bounds overflow in the mkkeywordhash.c code generator. Also add marks to omit keywords specific to generated columns when building with -DSQLITE_OMIT_GENERATED_COLUMNS. check-in: cc6a408183 user: drh tags: trunk
02:30
Slightly faster keyword hash table. check-in: f12e743e19 user: drh tags: trunk
2019-10-31
20:54
Correctly generate pre-UPDATE content for virtual columns that are used by foreign key constraints. Ticket [b9befa4b83a660cc] check-in: 40d3282ec2 user: drh tags: trunk
17:13
Add a few simple TCL test cases for generated columns. (Full test coverage of the generated column logic is provided separately by TH3.) check-in: acedb5c7f7 user: drh tags: trunk
13:16
Ignore differences in Expr.op2 in sqlite3ExprCompare() in cases where it does matter. Ticket [1d2a8efc6c3a595a]. check-in: 329820673a user: drh tags: trunk
