38 check-ins using file src/main.c version 20c6325c

2019-11-12
03:45
Remove a harmless unused variable. check-in: 28091a48 user: drh tags: trunk
2019-11-11
15:13
Remove an asm() block from build tool mksourceid.c, as it causes build failures on some systems and performance is not important at build-time. check-in: 8e100e6c user: dan tags: trunk
2019-11-10
11:09
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: 51027f08 user: drh tags: trunk
10:08
Remove an incorrect ALWAYS() macro. check-in: f7a74f89 user: drh tags: trunk
2019-11-09
15:31
Change the COLFLAG_NOTAVAIL bitmask so that it fits in the single-byte Walker.eCode field. check-in: 53847f5c user: drh tags: trunk
14:44
New dbsqlfuzz test cases added. check-in: 18c3a17d user: drh tags: trunk
14:38
Make sure the WITH stack in the Parse object is disabled following an error. check-in: de6e6d68 user: drh tags: trunk
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: b59f94e4 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: 34f64f11 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: 104a2beb 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: 9e07b489 user: drh tags: trunk
19:25
Minor simplification to the changes from check-in [36c11ad51f]. check-in: 7bc8205d 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: 36c11ad5 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: 77b1c90a user: drh tags: trunk
2019-11-04
12:49
Changes an unreachable testcase() into an assert(). check-in: 5710845b 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: ea20068e 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: 3be19e11 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: 9c795c4d user: drh tags: trunk
13:45
"STORED" is not actually a keyword. The parser looks for STORED as an ordinary identifier. check-in: 167cd574 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: 17e9f658 user: drh tags: trunk
00:00
Restore the on-line ".help" for the ".explain" command in the CLI. check-in: 28b8f103 user: drh tags: trunk
2019-11-01
18:52
Fix a harmless compiler warning. check-in: f0ebea35 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: b47513d2 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: 0a2eb949 user: drh tags: trunk
16:08
Add another missing column number translation to the foreign key logic. check-in: 32df5edc 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: e6c96ed9 user: drh tags: trunk
13:37
Fix an fts3 assert() that could fail when operating on a database containing corrupt records. check-in: 7c52f547 user: dan tags: trunk
12:14
Add missing column translations to foreign key logic. Ticket [c28a01da72f8957c] check-in: bc6a43e7 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: cc6a4081 user: drh tags: trunk
02:30
Slightly faster keyword hash table. check-in: f12e743e 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: 40d3282e 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: acedb5c7 user: drh tags: trunk
13:16
Ignore differences in Expr.op2 in sqlite3ExprCompare() in cases where it does matter. Ticket [1d2a8efc6c3a595a]. check-in: 32982067 user: drh tags: trunk
12:30
Enhance the TreeView logic to show information about Expr.op2 for FUNCTION and COLUMN nodes. check-in: aceeaf9e 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: 2978b65e 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: 84e02d77 user: drh tags: trunk
13:00
New tokens ALWAYS, GENERATED, and STORED used by generated columns should all be fallback tokens. check-in: 13fe6978 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: 4d424f30 user: drh tags: trunk
