Changes for version 1.1.23 - 2012-08-14

  • Major rewrite of transaction specification.
  • The main motivation is to remove the concept of 'steps' as this is a false dichotomy. Steps are actually functions themselves, the units of work are still functions. Eventually, a complex system will need to nest functions inside functions, to more than two levels of nesting. Why divide and limit into two levels (function-step)? So:
  • Everything is a bit clearer now
  • $tm interface is saner ($tm->call, easier to call function inside another)
  • No more mention of unused transaction status: e
  • New transaction statuses: v (rollback of undoing process), e (rollback of redoing process).
  • Recovery does not always means rollback (to R). For transactions in u and d status, we continue the undoing/redoing. For transactions in v and e status, we continue the rollback to final status C and U, respectively.
