VOSS 3.145.00.09 (beta) - changed Continuation Transaction behaviour
VOSS 3.145.00.09 (beta) is now available for download.
This release has changed commit behaviour of sub-transactions within a Continuation Transaction, such that if such a sub-transaction has a non-nil #dateAndTimeToRead (i.e. it sees only read-only historical versions of objects) then, if it is committed, it commits all the objects then locked in its parent Continuation Transaction (including its own objects), whether changed or not - the changed ones as changed, the unchanged ones as at their respective states at that #dateAndTimeToRead - as changes to their current (most recent, read/write) versions. (In the previous release (beta .08) only those objects which the sub-transaction had changed were committed.)
This new behaviour is more intuitively correct and useful, since it commits (”pastes forward”) the sub-transaction’s complete historical view, which could be, for example, an earlier product design configuration etc, with changes, as a new timestamped view. The previously current versions of those objects, now overwritten, still exist in their read-only historical states timestamped at their respective previous commits.
Because a transaction’s #dateAndTimeToRead may be any value, not just some actual commit timestamp, that now-overwritten world view is still there to see as at the appropriate timestamp, and could, if desired, be re-established as current simply by committing that historical view forwards with no changes but a new commit timestamp.
