| 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) | |

| 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) | |

| 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) | |
| 15:18 | Have fts5 reject attempts to insert a non-integer, non-null value into a rowid column with SQLITE_MISMATCH. (check-in: 4a9483f8 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 | Have fts3 ignore empty sets of parenthesis if built with SQLITE_ENABLE_FTS3_PARENTHESIS. (check-in: c93c6b45 user: dan tags: trunk) | |
| 05:48 | Avoid reading off the front of a page buffer when balancing a corrupt btree page. (check-in: cb505090 user: drh tags: trunk) | |

| 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) | |
| 20:17 | Relax the minimum size database file constraint on the dbtotxt utility program. (check-in: 97e723d7 user: drh tags: trunk) | |
| 20:17 | Improved detection of database corruption while balancing pages from an auto_vacuum database with overflow pages. Test cases in TH3. (check-in: 35f04235 user: drh tags: trunk) | |
| 00:58 | Move a local variable declaration into the outermost scope in which it is used. This fixes an ASAN warning. (check-in: ac3b6021 user: drh tags: trunk) | |

| 16:19 | Fix an off-by-one error on a Goto in the code generator, that only causes problems for a REPLACE on an INTEGER PRIMARY KEY in non-debug builds. Test case in TH3. (check-in: e35eb877 user: drh tags: trunk) | |
| 14:58 | Fix a problem with corrupt database handling in the fts3 matchinfo() function. (check-in: 703646b1 user: dan tags: trunk) | |

| 00:12 | Improved shadow table corruption detection in the matchinfo() function of FTS3. (check-in: 567be3bb user: drh tags: trunk) | |
| 00:07 | Indicate that the database may be corrupt in the fts3corrupt4.test test script. (check-in: 473626d5 user: drh tags: trunk) | |
