17:16
If "PRAGMA integrity_check" is run while the database is being written by a CONCURRENT transaction, do not consider unreferenced pages to be an error.

16:57
Add code to maintain indexes with expression arguments across DELETE, INSERT, and UPDATE statements. Legacy tests pass, but the new code paths are still largely untested. The query planner currently makes no effort to use expression indexes. check-in: efaabdb7 user: drh tags: index-expr

Fix a memory leak that might occur when compiling with SQLITE_OMIT_CHECK. check-in: 8f1d9f1f user: drh tags: trunk

2015-08-24
22:06
Remove duplicated line of code. check-in: 47280f2a user: mistachkin tags: begin-concurrent
20:54
Remove some redundant code: Call sqlite3ResolveExprListNames() rather than calling sqlite3ResolveExprNames() in a loop - in two places. check-in: bdaf6646 user: drh tags: trunk
20:21
Enhances the parser so that it accepts arbitrary expressions for the arguments of an index, though the code generator still rejects everything other than simple column names. The sqlite3RestrictColumnListSyntax() routine is removed since that feature is now handled by the parser. check-in: bed42116 user: drh tags: trunk
19:56
Change "BEGIN UNLOCKED" to "BEGIN CONCURRENT". check-in: ba1ab858 user: dan tags: begin-concurrent
