Size optimization in the authorizer error message generation logic. (check-in: 0367a4d5 user: drh tags: trunk)
18:23
In sqlite3ViewGetColumnNames(), return the number of errors, not an error code. (check-in: f13682ea user: drh tags: trunk)
18:17
The RTREE extension should return SQLITE_CORRUPT_VTAB, not just SQLITE_CORRUPT when it encounters incorrectly formatted shadow tables. (check-in: 0712f057 user: drh tags: trunk)
14:47
Remove an unnecessary branch from the [be436a7f4587ce517ddc] fix. (check-in: fb6ca99b user: drh tags: trunk)

18:13
Change the internal btree routine moveToRoot() to return SQLITE_EMPTY if the table is empty or if it has pgnoRoot==0. This simplifies the callers, making them smaller and faster.

Merge the latest enhancements from trunk. (check-in: 47e71695 user: drh tags: begin-concurrent)

15:19
Experimental changes that allow a WITHOUT ROWID virtual table to be writable as long as it has only a single-column PRIMARY KEY. (check-in: ab9ee4c1 user: drh tags: writable-vtab-without-rowid)

17:06
Prevent OSSFuzz from using debugging pragmas that are disabled in default builds and which generate lots of excess output. (check-in: cdc6494c user: drh tags: trunk)
16:42
Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening. This prevents the names from getting mangled by query transformations, and obviates hacks in the query flattener that attempt to work around the name mangling. The resulting code is smaller and faster and gives more consistent output. Fix to ticket [de3403bf5ae5f72ed]. (check-in: ade7ddf1 user: drh tags: trunk)
2017-07-30
20:30
Correctly handle an "INTEGER PRIMARY KEY UNIQUE" column in a WITHOUT ROWID table. This is a fix for ticket [bc115541132dad136] cherry-picked from [5216bfb73f1a49bdd]. (check-in: 5c8cb1ff user: drh tags: branch-3.20)

16:01
Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening. This prevents the names from getting mangled by query transformations, and obviates hacks in the query flattener that attempt to work around the name mangling. The resulting code is smaller and faster and gives more consistent output. This is an alternative fix to ticket [de3403bf5ae5f72ed]. (check-in: 09834279 user: drh tags: early-column-names)
14:56
Use the subquery column name, not the original SQL statement text, as the added AS clause in the query flattener. (Closed-Leaf check-in: 5df7f0e6 user: drh tags: flattener-column-names)
03:33
In the query flattener, only add AS clauses to output columns of the outer query that are copied directly from the inner query. Formerly, all columns of the outer query received an AS clause if they did not have one already. This is a proposed fix for ticket [de3403bf5ae5f72]. (check-in: 439cc5c5 user: drh tags: flattener-column-names)

Add the "atomic-batch-write" permutation to permutations.test. This permutation fails if not run on a file-system that supports atomic-batch-writes. (check-in: 9f1b83fa user: dan tags: batch-atomic-write)
16:32
Keep batch-atomic-writes turned on for journal_mode=MEMORY, but turn them off for synchronous=OFF. Refuse to compile with both SQLITE_MMAP_READWRITE and SQLITE_ENABLE_BATCH_ATOMIC_WRITE. Fix up some comments in the commit logic. (check-in: 2e80e19e user: drh tags: batch-atomic-write)
16:00

Do not use the flattening optimization for a sub-query on the RHS of a LEFT JOIN if that subquery reads data from a virtual table.
