Fix a windows-compatibility issue in the recently added schema6.test script. (check-in: 14e6c302 user: drh tags: trunk)
17:40
More consistent column names. Cherry-pick of [09834279] and [0c38dde45] as a fix for ticket [de3403bf5ae]. (check-in: be0e24a0 user: drh tags: branch-3.20)
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)
19:50
Add the schema6.test module for demonstrating schemas that generate identical and different content. (check-in: ac1da06a 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: 5216bfb7 user: drh tags: trunk)
2017-07-29
17:10
Merge latest trunk changes with this branch. (check-in: b42c8779 user: dan tags: server-process-edition)
17:02
New test cases for column name generation interacting with the query flattener. (Closed-Leaf check-in: 0c38dde4 user: drh tags: early-column-names)
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)
2017-07-28
22:22

2017-07-27
20:24

19:59
Increase the version number to 3.21.0 in anticipation for changes to go into the next release. (check-in: 0645f25c user: drh tags: trunk)
18:49
Merge the pointer-passing interface changes from the 3.20 branch. (check-in: c63903a4 user: drh tags: trunk)
18:43
Simplified documentation for the pointer passing interface. (check-in: 2dfcd9a8 user: drh tags: branch-3.20)
17:45
Add destructor functions for the pointer argument (NB: not the type string) to the sqlite3_bind_pointer() and sqlite3_result_pointer() interfaces. Use this new capability to resolve a pointer leak in the custom geometry function mechanism of the RTREE extension. (check-in: 5a2340b8 user: drh tags: branch-3.20)
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: d6684d2a user: drh tags: pointer-with-destructor)
15:53
Improved implementation of the destructor on pointer-passing interfaces. (check-in: 601ad679 user: drh tags: pointer-with-destructor)
03:48
Add a destructor argument to sqlite3_bind_pointer() and sqlite3_result_pointer(). (check-in: 3d9e841f user: drh tags: pointer-with-destructor)
