Experimental support for new sqlite3_bind_blob() and sqlite3_bind_text() interfaces that take an extra void* argument that is passed into the destructor in front of the object that is to be destroyed. Leaf check-in: 33a1924e user: drh tags: custom-destructors
20:28

20:20
Add the OP_ColumnsUsed opcode (when compiled with SQLITE_ENABLE_COLUMN_USED_MASK) as a hint to the b-tree layer as to which columns of a btree cursor will be used. (Backport from 3.8.11) check-in: b29e02f8 user: drh tags: branch-3.8.9

13:18
When saving the position of a cursor at the b-tree layer, allocate a few extra bytes at the end of the buffer used to save the key. Otherwise, if the key is corrupt, the code that restores the cursor position may overread the buffer by a little. check-in: 160b1e31 user: dan tags: trunk

20:39
Add new test file wal2big.test. check-in: e3e50bcd user: dan tags: wal2

03:59
Invoking the sqlite3_trace() or sqlite3_trace_v2() interfaces cancels any sqlite3_profile() that is running. check-in: ec63d350 user: drh tags: trunk

2018-12-05
23:56
Get rid of the hash table used to track IN operators in the sqlite3_normalized_sql() implementation. Use simple integer variables instead. check-in: 272dc74f user: drh tags: trunk
23:45
The sqlite3_normalized_sql() interface should not be transforming quoted identifier names into wildcards. Fix this, and at the same time simplify the code substantially. check-in: e8540377 user: drh tags: trunk
