14:59 | Add a new assert() statement to the snapshot-specific part of sqlite3WalBeginReadTrans(). (check-in: d8a12023be user: dan tags: trunk) | |
13:59 | Merge recent changes from trunk. Also remove unused variables to permit compiling with -Werror. (check-in: 57b700baa6 user: drh tags: onepass-delete-or) | |
13:51 | Simplified alignment constraints in the memory reuse logic of sqlite3VdbeMakeReady(). (check-in: e998513e44 user: drh tags: trunk) | |
12:44 | Add the experimental snapshot interface. Because it is experimental, it is subject to change or removal at a later date. (check-in: 9b124a5a31 user: drh tags: trunk) | |
