50 check-ins occurring around 5a2340b81faf0a29.

2017-07-30
19:50
Add the schema6.test module for demonstrating schemas that generate identical and different content. check-in: ac1da06a82 user: drh tags: trunk
18:40
Correctly handle an "INTEGER PRIMARY KEY UNIQUE" column in a WITHOUT ROWID table. This is a fix for ticket [bc115541132dad136], a problem discovered by OSSFuzz. check-in: 5216bfb73f user: drh tags: trunk
2017-07-29
17:10
Merge latest trunk changes with this branch. check-in: b42c87790e user: dan tags: server-process-edition
17:02
New test cases for column name generation interacting with the query flattener. Closed-Leaf check-in: 0c38dde454 user: drh tags: early-column-names
17:01
Update test program "tserver" to use a native pthreads mutex/condition variable to efficiently manage wal file checkpoints without the wal file growing indefinitely. check-in: 8299bdb7cb user: dan tags: server-process-edition
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: 09834279ae 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: 5df7f0e6a1 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: 439cc5c52c user: drh tags: flattener-column-names

16:42
In sqlite3_bind_pointer(), invoke the destructor if the bind index is out of range, like sqlite3_bind_blob() does. Closed-Leaf check-in: d6684d2a74 user: drh tags: pointer-with-destructor
15:53

14:04
A demonstration of how FTS3 cursor pointers can be passed from the MATCH operator to the snippet() function securely and opaquely without having to use the sqlite3_result_pointer() and sqlite3_value_pointer() interfaces. Closed-Leaf check-in: 49cf31da82 user: drh tags: pass-pointer-as-blob
03:48
