45 check-ins using file test/dbfuzz2.c version cf600006

2019-01-19
15:55
Avoid a division-by-zero error in fts5 caused by a corrupt database. check-in: 928e6221 user: dan tags: trunk
15:27
Remove a broken assert() triggered by a "PRAGMA max_page_count = N" invocation, where N is larger than the number of pages in the database image, but smaller than the number of pages in the database file. check-in: 7cd56cad user: dan tags: trunk
14:07
Fix a problem with using ALTER TABLE to rename a table or column when the database schema contains a trigger or view that itself contains an expression "<column> AND 0". check-in: 908ff7ff user: dan tags: trunk
2019-01-18
21:17
Fix a memory leak introduced by [55c5d72a]. check-in: fbd681dc user: dan tags: trunk
21:12
Fix a crash in the fts5vocab module caused by including a "term < NULL" term in a WHERE clause. check-in: 9e717c43 user: dan tags: trunk
21:03
Fix an infinite loop caused by a corrupt database in fts3. Also an undefined left-shift in fts5. check-in: 55c5d72a user: dan tags: trunk
20:15
Avoid passing a NULL pointer to memcpy in fts5, even if the database is corrupt. check-in: acccc980 user: dan tags: trunk
19:33
Typecasts added to the GeoPoly extension to avoid harmless UBSAN warnings. check-in: a1f6a093 user: drh tags: trunk
19:26
Fix problems causing undefined left-shift operations in the fts3 snippet() function. check-in: b90dbaed user: dan tags: trunk
18:52
Avoid integer overflow when computing the array of a bounding box with the rtree_i32 virtual table. check-in: b352f159 user: drh tags: trunk
17:53
Handle oversize floating point values carefully when converting to integers for the '%' binary operator. check-in: 048add13 user: drh tags: trunk
16:06
Fix a fairly obscure problem allowing an "ALTER TABLE RENAME col TO ..." statement to modify the schema in such a way as to break a reference within a trigger program. check-in: 64bec9e6 user: dan tags: trunk
14:53
Use the full 64-bit integer value in the argument to randomblob(). check-in: 05df5f7a user: drh tags: trunk
2019-01-17
20:19
Disable the xfer-optimization if the two tables have the same root page due to schema corruption. check-in: f31b3bd2 user: drh tags: trunk
20:06
Fix another corruption related crash in fts5. check-in: 4538d9af user: dan tags: trunk
19:33
Add the SQLITE_ENABLE_EARLY_CURSOR_CLOSE compile-time option which causes read cursors to be closed after their usefulness ends during a two-pass UPDATE. check-in: 7def6c8e user: drh tags: trunk
19:11
Fix a buffer overwrite that could occur when running an fts5 prefix query against a corrupt database. check-in: 3910b563 user: dan tags: trunk
17:39
Fix problems with joining two or more fts5_vocab tables that access the same underlying fts5 table. check-in: 49956395 user: dan tags: trunk
15:47
Sync up with the latest enhancements on trunk. check-in: 475a179a user: drh tags: apple-osx
15:40
Revamp the SrcList allocator routines to be methods of Parse instead of being methods of the "sqlite3" object, so that they can leave better error messages when the SrcList object grows too large. check-in: df08d472 user: drh tags: trunk
14:34
Limit the size of SrcList objects to 200 entries (compile-time configurable using -DSQLITE_MAX_SRCLIST=n). The maximum number of tables in a join has always been 64, so this is not a real constraint on capability. Limiting the size of a SrcList prevents DOS attacks (discovered by OSSFuzz) using crazy nexted CTE joins. check-in: 7cac614d user: drh tags: trunk
04:40
Fix a corner-case for the logic that cause an insert of a NULL into an INTEGER PRIMARY KEY column to be converted into a valid integer key, when the NULL results from a CASE expression that lacks an ELSE clause. check-in: 9a425051 user: drh tags: trunk
03:43
Ensure that the variable-length integer decoder in FTS3 never tries to left-shift a negative number. check-in: 10ffc1fe user: drh tags: trunk
01:06
Fix a failure in sqlite3ExprCompare() check-in: 835e2cc5 user: drh tags: trunk
2019-01-16
20:48

19:44
Fix a problem in the fts3 matchinfo() function with corrupt database handling. check-in: 24ed5fb6 user: dan tags: trunk
19:26
Fix a problem in the code generator for sorting results with SRT_EphemTab and a LIMIT clause. check-in: 49fcde2f user: drh tags: trunk
14:58
Fix a problem with renaming a column that is used as part of an ORDER BY on a compound SELECT within a database view or trigger. check-in: b4b57413 user: dan tags: trunk
12:05
Avoid a dangling pointer comparison when renaming a table that has a trigger that itself contains a window function with an (illegal) column reference in a FOLLOWING expression. check-in: d45bee36 user: dan tags: trunk
11:38
Fix a memory leak that could occur in fts3 when handling a corrupt database. check-in: 65cebb06 user: dan tags: trunk
2019-01-15
20:51
Fix a problem with ALTER TABLE and vector assignments in UPDATE statements within triggers. check-in: cc6cd753 user: dan tags: trunk
18:14
Handle SQL NULL values without crashing in the fts5 snippet() and highlight() functions. check-in: a5e9cc79 user: dan tags: trunk
16:14
Fix a buffer overread in fts3 caused by a corrupt record. check-in: e54efd60 user: dan tags: trunk

14:44
Fix a harmless memory leak in the Lemon parser generator utility program. check-in: 1caff0fb user: drh tags: trunk
14:31
Fix a problem triggered by DELETE statements with WHERE clauses that use the OR-optimization on some virtual tables. check-in: ecf5caa7 user: dan tags: trunk
2019-01-14
20:44
Add scalar function "prefix_length()" to ext/misc/prefixes.c. check-in: 0bf15505 user: dan tags: trunk
19:13
Fix a problem causing some Tcl test cases to fail with errors like "expected: [<multiline-whitespace>], got: []". check-in: 11b8a4cb user: dan tags: trunk
16:16
Add the "prefixes" table-valued function in the ext/misc folder. check-in: f0fd2163 user: drh tags: trunk
15:35
Fix a problem causing a crash if an fts5vocab table was created to query an fts3/4 FTS index. check-in: 9cd64ce4 user: dan tags: trunk
15:09
Fix a problem with querying a corrupt fts3 database. check-in: 65e50706 user: dan tags: trunk
13:32
When parsing a corrupt record using sqlite3VdbeRecordUnpack(), make sure that the resulting UnpackedRecord object is completely initialized, to avoid (harmless) MSAN warnings. check-in: ddc3697e user: drh tags: trunk
11:56

2019-01-13
20:23
In dbfuzz2, avoid using a malloc in the LLVMFuzzerInitialize() initializer routine, so that no memory leaks are reported. Also, show the version of SQLite being used when the -v option is on. check-in: 824f9324 user: drh tags: trunk
