Fix the windowB test module so that it works even if SQLite is built without JSON support. check-in: 807975c76b user: drh tags: trunk
18:27
Add the SQLITE_SUBTYPE flag, which may be passed to sqlite3_create_window_function() to indicate that the window function uses sqlite3_value_subtype() to check the sub-type of its arguments. check-in: ba2ebc3a34 user: dan tags: trunk
17:51
Add the SQLITE_SUBTYPE flag, which may be passed to sqlite3_create_window_function() to indicate to the core that the window function may call sqlite3_value_subtype() on its arguments. Closed-Leaf check-in: c12653d3d2 user: dan tags: mistake

2019-09-03
16:23
Updates to the default settings in Makefile.linux-gcc. check-in: 3044cf6917 user: drh tags: trunk
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

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

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

The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] check-in: dd66134817 user: drh tags: trunk
15:11
The expression "(X IS FALSE) BETWEEN FALSE AND TRUE" does not implie that X is not NULL. Ticket [fba33c8b1df6a915] check-in: 057fb8b180 user: drh tags: trunk
13:07
The expression "(x IS FALSE) IS FALSE" does not imply that X is not NULL. Ticket [a6408d42b9f44462] check-in: 45ff2b1f26 user: drh tags: trunk

Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. check-in: 616f5663b3 user: dan tags: trunk
15:06
Avoid assuming that for "~ (? AND FALSE)" to be true, "?" must not be NULL, just as we do for "NOT (? AND FALSE)". Fix for ticket [c0390363]. check-in: 84ae41fd2f user: dan tags: trunk
14:25
Fix a potential buffer overrun in fts5 caused by corrupted database records. check-in: c465d0eb47 user: dan tags: trunk

17:01
Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years. check-in: 7f5168a76a user: drh tags: trunk
10:05
If a TEMP TRIGGER references an auxiliary schema, and that auxiliary schema is detached, move the trigger to reference the TEMP schema before completing the detach, so that the trigger does not hold a dangling schema pointer. Ticket [ac8dd4a32ba4322f] check-in: 069c2f4c61 user: drh tags: trunk
