2018-10-08
23:29
Add the ability to open a database connection in -reuseschema mode in the CLI. Adjust memory allocation accounting so that a shared schema is allocated across each database sharing it. check-in: 3869b210 user: drh tags: reuse-schema
20:57
Fix a problem with using virtual tables via reuse-schema connections. check-in: e5897daf user: dan tags: reuse-schema
20:37
Merge fixes from trunk. check-in: 9c8255a1 user: drh tags: reuse-schema
20:04
Fix an issue with the new memstat.c extension. check-in: ce6e80b1 user: drh tags: trunk
18:58
Merge latest trunk changes into this branch. check-in: 2ac72114 user: dan tags: reuse-schema
18:55
Replace the new geopoly_reverse() function with geopoly_ccw(). The geopoly_ccw() function only reverses the vertex order if doing so is necessary to get the correct right-hand winding rule on the polygon. check-in: 07506694 user: drh tags: trunk
12:58
Add the geopoly_reverse() function to the GeoPoly extension. check-in: 690dd18a user: drh tags: trunk

Ensure each ALTER TABLE statement makes just a single SQLITE_ALTER_TABLE call to the authorizer function. Leaf check-in: dac28547 user: dan tags: alter-auth-callbacks
13:46
Add test cases and assert() statements to ensure that the authorizer is being called as expected from within ALTER TABLE. check-in: ff10d2c7 user: dan tags: trunk
2018-10-05
20:09
When the left-hand side of a WHERE clause contraint is a UNIQUE column, and that term of the WHERE clause is not used for indexing, assume that the term reduces the number of output rows by half. This is one proposed fix for ticket [e8b674241947eb3ba4] Leaf check-in: 5c243eec user: drh tags: unique-constraint-weights
15:10
Changes to geopoly to silience false-positive warnings coming out of clang. check-in: 11d9015f user: drh tags: trunk
2018-10-04
18:17
The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. Leaf check-in: 857a1b01 user: drh tags: query-planner-debug
2018-10-03
18:05
Add an ALWAYS on an unreachable branch in the ALTER TABLE logic. check-in: ebcd4523 user: drh tags: trunk

Change a type in shell.c.in from "int" to "sqlite3_int64" in order to avoid a compiler warning and possible integer overflow. check-in: bf0a6634 user: dan tags: trunk
2018-10-02

Add an additional assert() verifying mutex invariants on the unixShmSystemLock() routine in the unix VFS. check-in: cb151106 user: drh tags: trunk
