13:19
Enable sqlite3_deserialize() in the CLI. The --deserialize option associated with opening a new database cause the database file to be read into memory and accessed using the sqlite3_deserialize() API.

13:51
On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. check-in: 90cf32cd 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

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.

Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index.

Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. check-in: ad130bb8 user: drh tags: trunk

Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower. So the initial evidence is that this Expr refactoring experiment is not working... Leaf check-in: 24b0f66a user: drh tags: expr-simplify

16:06
Minor improvements to the permutations.test script. Most notably, a command like "permutations.test alter%" now runs all test scripts with names that match the LIKE pattern "alter%". Or, say, "permutations wal alter%" to run all alter% tests in wal mode. check-in: 3e1a2f66 user: dan tags: trunk
