| 21:54 | Fix the pager so that it remembers the name of the journal for an in-memory database as an empty string. This is important when committing a multi-database transaction that includes one or more attached memory databases. (CVS 6852) check-in: 31a5e819 user: drh tags: trunk | |

| 18:56 | Make the sqlite3BtreeMoveto function static, since it is only used from within btree.c. Remove unused function lockBtreeWithRetry from btree.c. (CVS 6850) check-in: 30d5ec62 user: danielk1977 tags: trunk | |
