| 17:19 | Fix to cause BtShared.db to be set correctly on shared-cache connections in SQLITE_THREADSAFE=0 builds. Added assert()s to verify the correct setting of BtShared.db. check-in: 2d96aeba user: drh tags: trunk | |
| 17:09 | Small performance and size optimization spotted while working on the shared-cache problem. check-in: 828958ff user: drh tags: trunk | |
| 02:06 | Add the "sqlite3 -sourceid" command in the TCL interface. Use that command and others to output additional information about the test configuration at the conclusion of a TCL test. check-in: 4f80440b user: drh tags: trunk | |
