Proper surrogate pair decoding added to JSON functions. See the mailing list bug report and [https://bugs.python.org/issue38749]. More test cases needed here, but it seems to work so far. check-in: 51027f08c0 user: drh tags: trunk
10:08

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
14:51
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

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

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

Add missing column translations to foreign key logic. Ticket [c28a01da72f8957c] check-in: bc6a43e7ee user: drh tags: trunk
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
12:30
Enhance the TreeView logic to show information about Expr.op2 for FUNCTION and COLUMN nodes. check-in: aceeaf9e28 user: drh tags: trunk
2019-10-30
18:50
Always disallow the use of non-deterministic functions in CHECK constraints, even date/time functions that use the 'now' or similar keywords. Provide improved error messages when this requirement is not met. Ticket [830277d9db6c3ba1] check-in: 2978b65ebe user: drh tags: trunk
16:29
Simplify the bytecode generation for SQL function calls such that the OP_Function or OP_PureFunc opcodes are coded directly, rather than using the intermediate OP_Function0 or OP_PureFunc0 - opcodes that are now removed. check-in: 84e02d773d user: drh tags: trunk
13:00
New tokens ALWAYS, GENERATED, and STORED used by generated columns should all be fallback tokens. check-in: 13fe6978b7 user: drh tags: trunk
2019-10-29
16:18
Remove the legacy_file_format PRAGMA. In its place, provide the SQLITE_DBCONFIG_LEGACY_FILE_FORMAT option to sqlite3_db_config(). Fix for ticket [6484e6ce678fffab] check-in: 4d424f3047 user: drh tags: trunk
03:39
Tighten the generated column requirement such that every table must have at least one non-generated column. Ticket [166347c6fc994155]. check-in: 4fba090e67 user: drh tags: trunk
03:30
Add a missing translation from table column numbers to storage table numbers while processing constraints on an UPDATE statement. Ticket [9621dd78a024d07a] check-in: 361ea81ae8 user: drh tags: trunk
01:26
Disallow tables that have only virtual columns. check-in: 591973217f user: drh tags: trunk
2019-10-28
13:54

13:07
Remove a NEVER() comparison from sqlite3ExprCompare(). check-in: f4285297e1 user: drh tags: trunk
04:20
ALWAYS macro added for coverage. check-in: a1e1ba9145 user: drh tags: trunk

Improved detection of attempts to use a generated column as part of the primary key. Ticket [91e86951016a6802] check-in: 6d1bbba9a0 user: drh tags: trunk
2019-10-26
23:51
Remove code from the constraint checker that generates virtual column values with the incorrect time. Turns out the the regular code for all other columns works correctly and so the incorrect special-case code is not actually needed. Fix for ticket [3ea175512444b0d1]. check-in: 5b4c0f2ddc user: drh tags: trunk
18:56
Remove redundant code resulting from a merge error on the previous check-in. check-in: 713fe86b8c user: drh tags: trunk
18:47
Add support for generated columns. check-in: b855acf183 user: drh tags: trunk
17:08
Performance optimization on sqlite3GenerateConstraintChecks() - bypass the loop that checks each column for NOT NULL constraints if it is known in advance that the table has no NOT NULL constraints. check-in: e3c3f4d787 user: drh tags: trunk
16:38
Clarify some comments and add assert() and testcase() macros to the replace-trigger recheck logic for ticket [c1e19e12046d23fe] check-in: 8c0042bd5c user: drh tags: trunk
16:02
Fix a problem in the legacy ".explain on" formatting when it is used on a query with more than 8 output columns. check-in: 070b49825c user: drh tags: trunk
15:40
Minor changes to help ensure the pointer returned by sqlite3VdbeGetOp() is not used after it becomes invalid. check-in: 346bdd49fb user: drh tags: trunk
12:27
Overnight, OSSFuzz helpfully pointed out a potential use-after-free bug in yesterdays changes, involving continued use of a pointer after the memory pointed to had been realloc()-ed. Thanks Google. check-in: c422afb507 user: drh tags: trunk
