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.

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

07:56
Merge further trunk changes. check-in: c2327a3b user: dan tags: begin-concurrent
03:05
Fix a couple instances of OOM handling in the json extension. check-in: 213a6c5c user: drh tags: trunk
01:32
