benwtrent opened a new issue, #13478: URL: https://github.com/apache/lucene/issues/13478
### Description It was noticed that the CMS intra-merge behavior was not fully tested. In an effort to do this, a change to override when the intra-merge scheduler is used has been drafted. https://github.com/apache/lucene/pull/13475 This PR has exposed many existing assertions that may all be weird testing failures. But a couple are more worrisome. In particular: ``` ./gradlew test --tests TestCodecHoldsOpenFiles.test -Dtests.seed=AA3C2FCDA0773874 -Dtests.locale=ar-PS -Dtests.timezone=Asia/Magadan -Dtests.asserts=true -Dtests.file.encoding=UTF-8 ``` Will periodically fail with an NPE on the `sort`: ``` org.apache.lucene.index.MergePolicy$MergeException: java.lang.NullPointerException: Cannot invoke "org.apache.lucene.search.Sort.getSort()" because the return value of "org.apache.lucene.index.LeafMetaData.getSort()" is null at __randomizedtesting.SeedInfo.seed([AA3C2FCDA0773874]:0) at app//org.apache.lucene.index.ConcurrentMergeScheduler.handleMergeException(ConcurrentMergeScheduler.java:764) at app//org.apache.lucene.index.ConcurrentMergeScheduler$MergeThread.run(ConcurrentMergeScheduler.java:756) Caused by: java.lang.NullPointerException: Cannot invoke "org.apache.lucene.search.Sort.getSort()" because the return value of "org.apache.lucene.index.LeafMetaData.getSort()" is null at org.apache.lucene.index.SortingCodecReader.assertCreatedOnlyOnce(SortingCodecReader.java:739) at org.apache.lucene.index.SortingCodecReader.getOrCreate(SortingCodecReader.java:721) at org.apache.lucene.index.SortingCodecReader.getOrCreateDV(SortingCodecReader.java:759) at org.apache.lucene.index.SortingCodecReader$7.getNumeric(SortingCodecReader.java:571) at org.apache.lucene.codecs.DocValuesConsumer$1.getNumeric(DocValuesConsumer.java:201) at org.apache.lucene.codecs.lucene90.Lucene90DocValuesConsumer$1.getSortedNumeric(Lucene90DocValuesConsumer.java:138) at org.apache.lucene.codecs.lucene90.Lucene90DocValuesConsumer.writeValues(Lucene90DocValuesConsumer.java:188) at org.apache.lucene.codecs.lucene90.Lucene90DocValuesConsumer.addNumericField(Lucene90DocValuesConsumer.java:133) at org.apache.lucene.tests.codecs.asserting.AssertingDocValuesFormat$AssertingDocValuesConsumer.addNumericField(AssertingDocValuesFormat.java:87) at org.apache.lucene.codecs.DocValuesConsumer.mergeNumericField(DocValuesConsumer.java:183) at org.apache.lucene.codecs.DocValuesConsumer.merge(DocValuesConsumer.java:142) at org.apache.lucene.codecs.perfield.PerFieldDocValuesFormat$FieldsWriter.merge(PerFieldDocValuesFormat.java:151) at org.apache.lucene.index.SegmentMerger.mergeDocValues(SegmentMerger.java:205) at org.apache.lucene.index.SegmentMerger.mergeWithLogging(SegmentMerger.java:325) at org.apache.lucene.index.SegmentMerger.lambda$merge$1(SegmentMerger.java:155) at org.apache.lucene.search.TaskExecutor$TaskGroup.lambda$createTask$0(TaskExecutor.java:117) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:317) at org.apache.lucene.index.ConcurrentMergeScheduler$CachedExecutor.lambda$execute$0(ConcurrentMergeScheduler.java:982) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1144) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:642) at java.base/java.lang.Thread.run(Thread.java:1583) ``` ### Version and environment details _No response_ -- This is an automated message from the Apache Git Service.
