Michael Beckerle reassigned DAFFODIL-1985: ------------------------------------------ Assignee: Michael Beckerle > beforeState in sequences prevents streaming behavior in I/O layer > ------------------------------------------------------------------ > > Key: DAFFODIL-1985 > URL: https://issues.apache.org/jira/browse/DAFFODIL-1985 > Project: Daffodil > Issue Type: Bug > Components: Back End > Affects Versions: 2.2.0 > Reporter: Michael Beckerle > Assignee: Michael Beckerle > Priority: Major > Fix For: 2.2.0 > > > The refactoring/rewrite of sequences used two saved states for arrays with > Points of uncertainty, a beforeState at the very start of the array, and a > priorState which the state prior to the current attempt to parse an > occurrance. > In a code review it was observed that this beforeState prevents streaming by > holding onto the I/O layer mark state for the entire array. > Arguably, the beforeState is not only unnecessary, but incorrect. Arrays > don't need a PoU before the entire array that doesn't advance when > occurrences are found. If the array is determined to exist, because at least > one occurrence exists, then failure of the entire array causes the enclosing > PoU to be determined, not an artificial one created at the start of the > array. > Remove beforeState to fix. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
