Обсуждение: Managing Rollback

Hi,

What do we mean in the last two lines of the following comment?
                       /* ----------------                        *              Here we are in the middle of a
transaction block but                        *              one of the commands caused an abort so
we do nothing                        *              but remain in the abort state. 
Eventually we will get                        *              to the "END TRANSACTION" which will set
things straight.                        * ----------------                        */               case TBLOCK_ABORT:
                   s->blockState = TBLOCK_INPROGRESS;                       AbortTransaction();
StartTransaction();                      break;
 

Haroldo.

It just means that nothing's going to happen until the user sends
COMMIT or ROLLBACK --- the xact.c state will remain the same until
then.
