- Upgrading Berkeley DB Applications

The C API for the Berkeley DB Transaction subsystem was reworked in the 4.0 release as follows:
| Historic functional interface | Berkeley DB 4.X method |
|---|---|
| txn_abort | DB_TXN->abort |
| txn_begin | DB_ENV->txn_begin |
| txn_checkpoint | DB_ENV->txn_checkpoint |
| txn_commit | DB_TXN->commit |
| txn_discard | DB_TXN->discard |
| txn_id | DB_TXN->id |
| txn_prepare | DB_TXN->prepare |
| txn_recover | DB_ENV->txn_recover |
| txn_stat | DB_ENV->txn_stat |
Applications calling any of these functions should update their calls to use the enclosing DB_ENV or DB_TXN handle's method (easily done as the first argument to the existing call is the correct handle to use).
As a special case, since applications might potentially have many calls to the txn_abort, txn_begin and txn_commit functions, those interfaces continue to work unchanged in the Berkeley DB 4.0 release.
In addition, the DB_ENV->txn_stat call has been changed in the 4.0 release to take a flags argument. To leave their historic behavior unchanged, applications should add a final argument of 0 to any calls made to DB_ENV->txn_stat.
