(#15260) ... * Fix NPE caused by realtime segment closing race, fix possible missing-segment retry bug. Fixes #12168, by returning empty from FireHydrant when the segment is swapped to null. This causes the SinkQuerySegmentWalker to use ReportTimelineMissingSegmentQueryRunner, which causes the Broker to look for the segment somewhere else. In addition, this patch changes SinkQuerySegmentWalker to acquire references to all hydrants (subsegments of a sink) at once, and return a ReportTimelineMissingSegmentQueryRunner if *any* of them could not be acquired. I suspect, although have not confirmed, that the prior behavior could lead to segments being reported as missing even though results from some hydrants were still included. * Some more test coverage.		2023-11-20 10:48:14 -08:00
