[jira] [Commented] (BEAM-12756) Negative value being returned for progress when using OffsetRangeTracker

["Luke Cwik (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-12756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17499626#comment-17499626 ] 

Luke Cwik commented on BEAM-12756:
----------------------------------

This was an internal Dataflow bug because of a conversion of a large double value needed to be turned into a saturated cast vs a static cast since in c++ a cast from a large double value beyond the bounds of an int64 returns the smallest negative integer.

> range.getFrom() returns 1 and range.getTo() returns 9223372036854775807 (Long.MAX_VALUE).  In the returned Progress object, workCompleted is 0.0 and workRemaining is 9.223372036854776E18
> Somehow, in the Dataflow backend, it becomes -9223372036854775808
