Bump Lucene.Net from 4.8.0-beta00012 to 4.8.0-beta00015

[dependabot]

Bumps Lucene.Net from 4.8.0-beta00012 to 4.8.0-beta00015.

Release notes

Sourced from Lucene.Net's releases.

v4.8.0-beta00015

This release contains important bug fixes, performance enhancements, concurrency improvements, and improved debugging support (full stack traces, consistent exception types, attributes for debug view, and structurally formattable lists).

Much of the exception handling has been changed so it is recommended to test thoroughly, especially if your application relies on catching exceptions from Lucene.NET for control flow. The full extent of the exception handling changes are not documented here, but can be viewed at apache/lucenenet#476.

Known Issues

• Lucene.Net.Index.IndexWriter::Dispose(): Using Thread.Interrupt() to shutdown background threads in .NET is problematic because System.Threading.ThreadInterruptedException could be thrown on any lock statement with contention on it. This includes lock statements on code that we depend on or custom components that are engaged during a Commit() (such as a custom Directory implementation). These exceptions may cause Commit() to fail in unexpected ways during IndexWriter.Dispose(). While this affected all prior releases to a much larger degree, this release provides a partial solution using UninterruptableMonitor.Enter() to ensure these exceptions are ignored and the Thread.Interrupt() state restored, which greatly reduces the chance a Commit() could be broken or a deadlock can occur. This problem will not affect applications that do not call Thread.Interrupt() to shut down a thread. It is recommended never to use Thread.Interrupt() in conjunction with IndexWriter, ConcurrentMergeScheduler, or ControlledRealTimeReopenThread.

Change Log

Breaking Changes

• #455 - lucene-cli: Changed exit codes to well-defined constants to make testing simpler
• #407 - Moved all Document extensions to the Lucene.Net.Documents.Extensions namespace and added tests for DocumentExtensions in Lucene.Net.Tests._J-S, Lucene.Net.Tests.ICU and Lucene.Net.Tests.Facet. Added guard clauses and updated documentation of Document extension methods and some related fields.
• #474 - Lucene.Net.TestFramework.Util.TestUtil: Renamed method parameters from abbreviations to whole words to follow .NET API conventions and improved documentation.
• #475 - Lucene.Net.Grouping: Refactored and improved GroupingSearch Search API and added GroupByField() and GroupByFunction() methods.
• #479 - Moved Lucene.Net.Join types to Lucene.Net.Search.Join namespace
• Marked public exception constructors that were meant only for testing internal (affects only .NET Framework)
• #446, #476 - Redesigned exception handling to ensure that exception behavior is the same as in Lucene and so we consistently throw the closest .NET equivalent exception across all of the projects.
• #480 - Changed Cardinality() methods to Cardinality property. Added obsolete Cardinality() extension methods to the namespace of each of the pertinent types for backward compatibility.
  • Lucene.Net.Index.RandomAccessOrds
  • Lucene.Net.Util.FixedBitSet
  • Lucene.Net.Util.Int64BitSet
  • Lucene.Net.Util.OpenBitSet
  • Lucene.Net.Util.PForDeltaDocIdSet
  • Lucene.Net.Util.WAH8DocIdSet
• #481 - Lucene.Net.Index.Term: Changed Text() method into Text property. Added an obsolete Text() extension method to Lucene.Net.Index namespace for backward compatibility.
• #482 - Lucene.Net.BinaryDocValuesField: Changed fType static field to TYPE (as it was in Lucene) and added obsolete fType field for backward compatibility.
• #483 - Changed all GetFilePointer() methods into properties named Position to match FileStream. Types affected: Lucene.Net.Store.IndexInput (and subclasses), Lucene.Net.Store.IndexOutput (and subclasses). Added obsolete extension methods for each type in Lucene.Net.Store namespace for backward compatibility.
• #484 - Lucene.Net.QueryParser: Factored out NLS/IMessage/Message support and changed exceptions to use string messages so end users can elect whether or not to use .NET localization, as is possible with any other .NET exception type.
• #484 - Lucene.Net.QueryParsers.Flexible.Messages: Removed entire namespace, as we have refactored to use .NET localization rather than NLS
• #484 - Lucene.Net.Util: Removed BundleResourceManagerFactory and IResourceManagerFactory, as these were only to support NLS. The new approach to localizing messages can be achieved by registering QueryParserMessages.SetResourceProvider(SomeResource.ResourceManager, SomeOtherResource.ResourceManager) at application startup using any ResourceManager instance or designer-generated resource's ResourceManager property.
• #497, #507 - Factored out Lucene.Net.Support.Time in favor of J2N.Time. Replaced all calls (except Lucene.Net.Tests.Search.TestDateFilter) that were Environment.TickCount and Time.CurrentTimeMilliseconds() to use Time.NanoTime() / Time.MillisecondsPerNanosecond for more accurate results. This may break some concurrent applications that are synchronizing with Lucene.NET components using Environment.TickCount.
• #504 - Lucene.Net.Highlighter.VectorHiglight.ScoreOrderFragmentsBuilder.ScoreComparer: Implemented singleton pattern so the class can only be used via the Default property.
• #502 - Lucene.Net.QueryParser.Flexible.Core.Nodes.IQueryNode: Added RemoveChildren() method from Lucene 8.8.1 to fix broken RemoveFromParent() method behavior (applies patch LUCENE-5805). This requires existing IQueryNode implementations to implement RemoveChildren() and TryGetTag().
• #502 - Lucene.Net.QueryParser.Flexible.Core.Nodes.IQueryNode: Added TryGetTag() method to simplify looking up a tag by name.
• #528 - Lucene.Net.Analysis.Stempel.Egothor.Stemmer.MultiTrie: Changed protected m_tries field from List<Trie> to IList<Trie>
• #528 - Lucene.Net.Search.BooleanQuery: Changed protected m_weights field from List<Weight> to IList<Weight>
• #528 - Lucene.Net.Search.DisjunctionMaxQuery: Changed protected m_weights field from List<Weight> to IList<Weight>

Bugs

• #461 - Lucene.Net.Grouping.GroupingSearch::GroupByFieldOrFunction<TGroupValue>(): Fixed casting bug of allGroupsCollector.Groups by changing the cast to ICollection instead of IList.
• #453, #455 - lucene-cli: Made appsettings.json file optional. This was causing a fatal FileNotFoundException after installing lucene-cli without adding an appsettings.json file.
• #464 - Lucene.Net.Codecs.SimpleText.SimpleTextStoredFieldsWriter + Lucene.Net.Codecs.SimpleText.SimpleTextTermVectorsWriter: Fixed Abort() methods to correctly swallow any exceptions thrown by Dispose() to match the behavior of Lucene 4.8.0.
• #394, #467 - Lucene.Net NuGet does not compile under Visual Studio 2017. Downgraded Lucene.Net.CodeAnalysis.CSharp and Lucene.Net.CodeAnalysis.VisualBasic from .NET Standard 2.0 to .NET Standard 1.3 to fix.
• #471 - Lucene.Net.Documents.FieldType: Corrected documentation to reflect the actual default of IsTokenaized as true and NumericType as NumericType.NONE, and to set to NumericType.NONE (rather than null) if the field has no numeric type.
• #476 - Lucene.Net.Analysis.Common.Util.CharArraySet: Throw NotSupportedException when the set is readonly, not InvalidOperationException to match .NET collection behavior
• #476 - Lucene.Net.Codecs.Bloom.BloomFilteringPostingsFormat::FieldsConsumer(): Throw NotSupportedException rather than InvalidOperationException
• #476 - Lucene.Net.Codecs.Lucene42.Lucene42DocValuesProducer::LoadNumeric(): Throw AssertionError rather than InvalidOperationException
• #476 - Lucene.Net.Store.CompoundFileDirectory::ReadEntries(): throw AssertionError rather than InvalidOperationException
