19:33
Typecasts added to the GeoPoly extension to avoid harmless UBSAN warnings. (check-in: a1f6a093ac user: drh tags: trunk)
19:26
Fix problems causing undefined left-shift operations in the fts3 snippet() function. (check-in: b90dbaed30 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: b352f1590d user: drh tags: trunk)
17:53
Handle oversize floating point values carefully when converting to integers for the '%' binary operator. (check-in: 048add13fc 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: 64bec9e621 user: dan tags: trunk)
14:53
Use the full 64-bit integer value in the argument to randomblob(). (check-in: 05df5f7aea 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: f31b3bd2a6 user: drh tags: trunk)
20:06
Fix another corruption related crash in fts5. (check-in: 4538d9afe4 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: 7def6c8edd 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: 3910b5639d 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: 49956395e1 user: dan tags: trunk)
15:47
Sync up with the latest enhancements on trunk. (check-in: 475a179a27 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: df08d472b0 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: 7cac614d5d 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: 9a425051e7 user: drh tags: trunk)
03:43

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: b4b5741366 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: d45bee36f2 user: dan tags: trunk)
11:38

2019-01-14
20:44
Add scalar function "prefix_length()" to ext/misc/prefixes.c. (check-in: 0bf1550507 user: dan tags: trunk)

16:16
Add the "prefixes" table-valued function in the ext/misc folder. (check-in: f0fd2163fc user: drh tags: trunk)

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: 824f932469 user: drh tags: trunk)
20:17
Relax the minimum size database file constraint on the dbtotxt utility program. (check-in: 97e723d746 user: drh tags: trunk)
