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

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.

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

For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign key constraints that causes SQLite to clobber any existing row without separately checking for it.
