16:23

14:27
When we play games with COLLATE in order to commute an operator in the WHERE clause processing, be sure not to use the commuted operator to qualify a partial index, as insufficient COLLATE information is preserved to verify that the expression will correctly qualify the index. Ticket [767a8cbc6d20bd68] (check-in: 5351e920f4 user: drh tags: trunk)
2019-09-02
22:13

02:21
When applying the IN_INDEX_NOOP optimization and the LHS has REAL affinity, also apply REAL affinity to each element of the RHS. Ticket [2841e99d104c6436]. (check-in: 88833a9c28 user: drh tags: trunk)
01:25
Fix an obsolete comment that defines the meaning of one of the parameters to the sqlite3FindInIndex() subroutine. No changes to code. (check-in: 0c946f0846 user: drh tags: trunk)
00:58
When computing an expression value for an index-on-expression or a CHECK constraint and the expressions uses a REAL table column, but the value of that column is an integer (in other words, when it is using the store-real-as-integer optimization) be sure to promote the value to real before evaluating the expression. Ticket [57af00b6642ecd68]. (check-in: 0658c16e31 user: drh tags: trunk)
2019-09-01
23:36

Mark new VDBE branches never taken. (check-in: 83c2adffbf user: drh tags: trunk)
20:13
Improvements to the algorithm that determines which SELECT in a sequence of nested SELECT statements that an aggregate function belongs to. This resolves an issue identified by dbsqlfuzz. (check-in: d768007473 user: drh tags: trunk)
17:14
If a DELETE trigger fired by an UPDATE OR REPLACE statement deletes the row being updated, do not attempt to proceed with the original UPDATE operation. Fix for [d6a0fbc1]. (check-in: 4145b3e050 user: dan tags: trunk)
01:33

2019-08-30
23:56
When the affinity of a table column is INT or REAL, make the affinity of corresponding index columns NUMERIC. This increases the precision of index lookups for large numbers so that it matches the precision of ordinary comparison operators. Ticket [40812aea1fde9594] (check-in: e0d909c740 user: drh tags: trunk)
23:15
Make sure OP_RealAffinity has been applied to all columns of type REAL in the excluded.* pseudo-table of an UPSERT. Ticket [5a3dba8104421320] (check-in: 67381daded user: drh tags: trunk)
21:52
Improvements to VDBE tracing. No changes to code in normal deliverables. (check-in: 54553bf16f user: drh tags: trunk)

18:02
Back out the change at [47cd634c98b502d4] which was incorrect. Add a test case so that we don't accidently back out that change again. (check-in: 596ac2a4ea user: drh tags: trunk)
17:28
Add further comments to window.c. (check-in: 900464567b user: dan tags: trunk)
16:46
New test cases for window functions with RANGE BETWEEN and DESC NULLS FIRST. (check-in: f7002f86c7 user: drh tags: trunk)
