+# Lucene.NET 4.8.0-beta00017 Release Notes
+
+---
+
+> This release contains many bug fixes, performance improvements, and other
housekeeping/cleanup tasks. It is the largest update to Lucene.NET 4.8.0 to
date.
+>
+> [J2N 2.1](https://github.com/NightOwl888/J2N/releases/tag/v2.1.0) and [ICU4N
60.1.0-alpha.436](https://github.com/NightOwl888/ICU4N/releases/tag/v60.1.0-alpha.436)
have had major updates which will lay the groundwork for supporting
System.Memory types in Lucene.NET, but those updates will be included in a
later release. However, both libraries have had a significant reduction in the
number of heap allocations used across their codebases and those improvements
have a direct impact on ho [...]
+>
+> We are including .NET Core support for Lucene.Net.OpenNLP for the first time
using the IKVM `MavenRefernence` feature. The IKVM distribution is quite large
and due to disk space limitations of our CI enviornment we had to reference an
older version of both IKVM and IKVM.Maven.Sdk. These package references may be
upgraded by end users to use a newer version without any risk of breaking
changes.
+
+## Change Log
+
+### Breaking Changes
+
+- Lucene.Net.Util.OfflineSorter: Refactored to base file tracking on
FileStream rather than FileInfo, which gives us better control over temp file
deletion by specifying the `FileOptions.DeleteOnClose` option. We also use
random access so we don't need to reopen streams over files except in the case
of ExternalRefSorter.
+- Refactored CharArraySet and CharArrayMap (now CharArrayDictionary)
([#762](https://github.com/apache/lucenenet/pull/762))
+- Lucene.Net.Analysis.Kuromoji.Token: Changed these methods into properties:
`IsKnown()` to `IsKnown`, `IsUnknown()` to `IsUnknown`, `IsUser()` to `IsUser`.
+- Added guard clauses for all TokenAttribute members
+- Lucene.Net.Index.IndexReader: De-nested IReaderClosedListener and renamed to
IReaderDisposedListener.
+- Lucene.Net.Index.IndexWriter: Fixed `Dispose()` overloads so there is no
method signature conflict between the public `Dispose(waitForMerges)` method
and the protected `Dispose(disposing)` method that can be overridden and called
from a finalizer. See [#265](https://github.com/apache/lucenenet/pull/265).
+- Lucene.Net.Search.FieldCacheRangeFilter<T>: Changed accessibility from
protected internal to private protected. This class was not intended to be
subclassed by users. (see [#677](https://github.com/apache/lucenenet/pull/677))
+- Lucene.Net.Search.Suggest.Fst.ExternalRefSorter: Changed temp path
generation to use `FileSupport.CreateTempFile()` with named prefix and
extension because it more closely matches Lucene and makes the files more
easily identifiable.
+- Lucene.Net.Util.OfflineSorter: Changed `DefaultTempDir()` to
`GetDefaultTempDir()`.
+- Lucene.Net.Analysis.SmartCn.SmartChineseAnalyzer: Changed
`GetDefaultStopSet()` to `DefaultStopSet`. Marked `GetDefaultStopSet()`
obsolete.
+- Lucene.Net.Analysis.Kuromoji.JapaneseAnalyzer: Changed `GetDefaultStopSet()`
and `GetDefaultStopTags()` to `DefaultStopSet` and `DefaultStopTags`,
respectively. Marked the old methods obsolete.
+- Fixed ArgumentOutOfRange parameters so the message is passed into the 2nd
parameter, not the first (which is for argumentName). Fixes
[#665](https://github.com/apache/lucenenet/pull/665). Also addressed potential
int overflow issues when checking for "index + length must be <= array length".
+- Remove .NET 4.5, .NET 4.5.1, and .NET 4.5.2 support and update website
framework versions ([#650](https://github.com/apache/lucenenet/pull/650))
+- Lucene.Net.IndexWriter.IEvent: Marked internal (as it was in Java). This
interface is only used in non-public contexts by Lucene.
+- Remove virtual on methods that are being called from constructors
([#670](https://github.com/apache/lucenenet/issues/670) - see PRs linked to
this issue)
+- Lucene.Net.Util.PriorityQueue<T>: Replaced `(int, bool)` constructor
and removed constructor call to virtual `GetSentinelObject()` method
([#820](https://github.com/apache/lucenenet/pull/820))
+- Lucene.Net.Util: Added ValuePriorityQueue<T> to utilize stack
allocations where possible
([#826](https://github.com/apache/lucenenet/pull/826))
+- Use factory classes for DirectoryTaxonomyWriter and DirectoryTaxonomyReader
to get configs ([#847](https://github.com/apache/lucenenet/pull/847))
+- Replicator no longer attempts to deserialize exception types
([#968](https://github.com/apache/lucenenet/pull/968))
+- Rename `IndexWriter.NextMerge()` to `GetNextMerge()`
([#990](https://github.com/apache/lucenenet/pull/990))
+- Lucene.Net.Search.ReferenceContext<T>: Converted to ref struct and
reworked
`TestControlledRealTimeReopenThread.TestStraightForwardDemonstration()` to
verify functionality ([#925](https://github.com/apache/lucenenet/pull/925))
+
+### Bug Fixes
+
+- Lucene.Net.Util.OfflineSorter: Added back original tests using FileInfo and
fixed bugs that were preventing the original behavior
+- Lucene.Net.Tests.Store.TestRAMDirectory: Fixed teardown to retry file
deletion if they are locked by another process.
+- Aligned disposable patterns
([#746](https://github.com/apache/lucenenet/pull/746))
+- Changed TokenAttribute usage from concrete implementation type to interface
type to align with Lucene 4.8.0. We were using the concrete type in several
places where it shouldn't have been.
+- Lucene.Net.Util.OfflineSorter: Fixed the `Sort()` and `SortPartition()`
methods so they use the `tempDirectory` parameter that is passed through the
constructor, as was the case in Lucene. Added a constructor overload to specify
the directory as a string (a .NET convention).
+- Lucene.Net.Analysis.Kuromoji.Util.CSVUtil: Applied SOLR-9413 patch to fix
the `QuoteEscape()` method and add tests. Fixes
[#660](https://github.com/apache/lucenenet/pull/660).
+- Lucene.Net.Search.Similarities: Statically imported SimilarityBase where
appropriate so the Log2 method doesn't have to be qualified (like in Lucene).
Fixes [#694](https://github.com/apache/lucenenet/pull/694).
+- Fixed a bug where the CharArraySet returned from DefaultStopSet in all
analyzers was returning a static writable instance instead of a readonly
instance as per the docs.
+- Lucene.Net.Tests.Index.TestIndexWriter: Finished port of
RandomFailingFieldEnumerable. Fixes
[#695](https://github.com/apache/lucenenet/pull/695).
+- Lucene.Net.Benchmark.Support.TagSoup.Parser::SetProperty(): Removed
duplicate guard clause
+- Lucene.Net.Analysis.Cjk.CJKBigramFilter: Changed the value of ALL to set all
flags (was 0xff instead of 0xffff). Fixes
[#657](https://github.com/apache/lucenenet/pull/657).
+- Order of precedence for translation of `Remove()` method args in
FrenchStemmer.cs ([#654](https://github.com/apache/lucenenet/pull/654))
+- Fixed Infinite loop in HttpClientBase
+- Fixed throw statement in BinaryDictionary
+- Fixed use of insecure `Path.GetTempFileName` in ExternalRefSorter
([#651](https://github.com/apache/lucenenet/pull/651))
+- Lucene.Net.Search.package.md: Corrected link to TooManyClausesException
+- Fix AssertionError in JapaneseTokenizer backtrace LUCENE-10059
([#777](https://github.com/apache/lucenenet/pull/777))
+- Lucene.Net.Util.RandomizedContext: Create a separate instance of
`Randomizer()` for each thread initialized with the same seed. Fixes
[#843](https://github.com/apache/lucenenet/issues/843).
+- TestIndexWriterOnJRECrash: Removed using block to ensure that our original
CheckIndex error bubbles up instead of any issue disposing (or
double-disposing) the directory.
+- Lucene.Net.Documents.DateTools: Convert `DateTimeKind.Unspecified` dates to
UTC, otherwise they can produce ArgumentOutOfRangeException. Fixes
[#772](https://github.com/apache/lucenenet/issues/772).
+- Lucene.Net.Store: Fixed several `Dispose()` methods so they are safe to be
called multiple times ([#854](https://github.com/apache/lucenenet/pull/854))
+- Lucene.Net.QueryParsers.Classic.QueryParserTokenManager: Removed
initialization code that caused writing a BOM to standard out upon creation.
([#902](https://github.com/apache/lucenenet/pull/902))
+- Lucene.Net.Search.FieldComparer.TermValComparer: Fixed sorting ambiguity
between empty fields and missing fields
([#912](https://github.com/apache/lucenenet/pull/912))
+- Fix for DocumentsWriter concurrency (fixes #935, closes #886)
([#940](https://github.com/apache/lucenenet/pull/940))
+- Finalizer fix in IndexReader
([#951](https://github.com/apache/lucenenet/pull/951))
+- Fix for Lucene.Net.Util.SystemConsole throwing not supported exception in
.NET MAUI app running on Android/iOS
([#952](https://github.com/apache/lucenenet/pull/952))
+- Fix TermStats.TermText access, add CLI comments and 1 CLI bug fix
([#963](https://github.com/apache/lucenenet/pull/963))
+
+### Performance
+
+- Lucene.Net.Support.Arrays::CopyOfRange(): Use the `Copy()` method rather
than a for loop for a ~10x improvement in performance.
+- Lucene.Net.Support.Arrays::CopyOf(): Use the `Copy()` method rather than a
for loop for a ~10x improvement in performance.
+- Lucene.Net.Support.Arrays::Fill(): Replaced for loop implementation with
`Array.Fill()` or `Span.Fill<T>()` depending on platform.
+- Lucene.Net.Support.Arrays: Added `Copy()` overloads that use the most
efficient (known) copy method for the platform and data type based on
benchmarks. Replaced all occurrences of `Array.Copy()` and `Buffer.BlockCopy()`
with `Arrays.Copy()`.
+- Lucene.Net.Support.DictionaryExtensions: Reduced dependency on the `Put()`
method and added documentation to indicate that it doesn't work with
non-nullable value types. Also documented the `PutAll()` method and added guard
clause.
+- Lucene.Net.Analysis.Sinks.DateRecognizerSinkFilter: Prefer
`ReadOnlySpan<char>` overloads of `DateTime.TryParse()` and
`DateTime.TryParseExact()`, when available.
+- Lucene.Net.Analysis.Util.HTMLStripCharFilter: Refactored to remove YyText
property (method) which allocates a string every time it is called. Instead, we
pass the underlying array to `J2N.Numerics.TryParse()` and
`OpenStringBuilder.Append()` with the calculated startIndex and length to
directly copy the characters without allocating substrings.
+- Lucene.Net.Analysis.Util.OpenStringBuilder: Added overloads of
`UnsafeWrite()` for string and ICharSequence. Optimized `Append()` methods to
call `UnsafeWrite` with index and count to optimize the operation depending on
the type of object passed.
+- Lucene.Net.Analysis.Ga.IrishLowerCaseFilter: Use stack and spans to reduce
allocations and improve throughput.
+- Lucene.Net.Analysis.Th.ThaiWordBreaker: Removed unnecessary string
allocations and concatenation. Use CharsRef to reuse the same memory. Removed
Regex and replaced with UnicodeSet to detect Thai code points.
+- Lucene.Net.Analysis.In.IndicNormalizer: Refactored ScriptData to change
`Dictionary<Regex, ScriptData>` to `List<ScriptData>` and eliminated
unnecessary hashtable lookup. Use static fields for unknownScript and
`[ThreadStatic]` `previousScriptData` to optimize character script matching.
+- Lucene.Net.Analysis.In.IndicNormalizer: Replaced static constructor with
inline `LoadScripts()` method. Moved location of scripts field to ensure
decompositions is initialized first.
+- Lucene.Net.Analysis.Ja.GraphvizFormatter: Removed unnecessary surfaceForm
string allocation.
+- Lucene.Net.Analysis.Util.SegmentingTokenizerBase: Removed unnecessary string
allocations that were added during the port due to missing APIs.
+- Lucene.Net.Util.TestUnicodeUtil::TestUTF8toUTF32(): Added additional tests
for `ICharSequence` and `char[]` overloads, changed the original test to test
string.
+- Lucene.Net.Analysis.Miscellaneous.StemmerOverrideFilter: Added overloads to
Add for `ICharSequence` and `char[]` to reduce allocations. Added guard clauses.
+- Lucene.Net.Analysis.Util.CharacterUtils: Use spans and stackalloc to reduce
heap allocations when lowercasing. Added system property named "maxStackLimit"
that defaults to 2048 bytes.
+- Lucene.Net.Analysis.CharFilters.HTMLStripCharFilter: Removed allocation
during parse of hexadecimal number by using J2N.Numerics.Int32 to specify index
and length. Also added a CharArrayFormatter struct to defer the allocation of
constructing a string until after an assertion failure.
+- Lucene.Net.Codecs.SimpleText.SimpleTextUtil::Write(): Removed unnecessary
`ToCharArray()` allocation
+- Lucene.Net.Document.CompressionTools::CompressString(): Eliminated
unnecessary `ToCharArray()` allocation
+- Use `StringBuilder.Append(char)` instead of `StringBuilder.Append(string)`
when the input is a constant unit string.
([#708](https://github.com/apache/lucenenet/pull/708))
+- Lucene.Net.Util.MergedEnumerator: Changed from using inline string
conversions when the generic type is string to
J2N.Collections.Generic.Comparer<T>, which is statically initialized with the
optimal comparer that matches Java behaviors.
+- Lucene.Net.Index.BaseCompositeReader: Removed unnecessary list allocation
+- Lucene.Net.Analysis.TokenAttributes.CharTermAttribute: Optimized char
copying on `Append()` and `Subsequence()`
([#899](https://github.com/apache/lucenenet/pull/899))
+- Lucene.Net.Facet.Taxonomy.WriterCache.CharBlockArray: Compare equality and
calculate hash code without allocating
([#900](https://github.com/apache/lucenenet/pull/900))
+- Restore fsync behavior in FSDirectory via P/Invoke, fixes significant
performance regression when running on .NET 8
([#938](https://github.com/apache/lucenenet/pull/938))
+- Use concrete ConcurrentHashSet instead of abstraction for performance
([#960](https://github.com/apache/lucenenet/pull/960))
+
+### Improvements
+
+- Bumped version of most dependencies, including J2N and ICU4N. Fixed minimum
versions of transitive dependencies that were vulnerable or deprecated.
+- Lucene.Net.Support.IO (BinaryReaderDataInput + BinaryReaderDataOutput):
Deleted, as they are no longer in use.
+- Lucene.Net.Support.IO.FileSupport: Added `CreateTempFileAsStream()` method
overloads to return an open stream for the file so we don't have to rely on the
operating system to close the file handle before we attempt to reopen it.
+- Lucene.Net.Support.IO: Added FileStreamOptions class similar to the one in
.NET 6 to easily pass as a method parameter.
+- Align InputStreamDataInput and OutputStreamDataOutput closer to the Java
Source ([#769](https://github.com/apache/lucenenet/pull/769))
+- Reviewed to ensure we are consistently using `Arrays.Fill()` instead of the
(slower) `Array.Clear()` method or a for loop.
+- Lucene.Net.Analysis.Util.BufferedCharFilter: Implemented `Peek()` method.
Added overrides for `Span<T>` and `Memory<T>` based methods to throw
NotSupportedException. Added doc comments.
+- Lucene.Net.Analysis.Util.BufferedCharFilter: Check for CharFilter type inline
+- Lucene.Net.Analysis.Util.BufferedCharFilter: Use UninterruptableMonitor for
consistency (missed a couple)
+- Lucene.Net.Queries.Mlt.MoreLikeThis: Use `StringBuilder.Append(char)`
instead of `StringBuilder.Append(string)` when the input is a constant unit
string (see [#674](https://github.com/apache/lucenenet/pull/674))
+- Changed all internal constructors of abstract classes to private protected.
(fixes [#677](https://github.com/apache/lucenenet/pull/677))
+- Changed all protected internal constructors of abstract classes to
protected. (fixes [#677](https://github.com/apache/lucenenet/pull/677))
+- Changed all public constructors of abstract classes to protected, except
where it would be a problem for Reflection calls. (fixes
[#677](https://github.com/apache/lucenenet/pull/677))
+- ci: Added sonar workflow
([#709](https://github.com/apache/lucenenet/pull/709))
+- Lucene.Net.Support.IO.FileSupport::GetFileIOExceptionHResult(): Avoid
`Path.GetTempFileName()` because it is not secure.
https://rules.sonarsource.com/csharp/RSPEC-5445
+- Lucene.Net.Util.OfflineSorter (ByteSequencesReader + ByteSequencesWriter):
Added constructor overloads to pass the file name as a string (.NET convention)
+- Lucene.Net.Util.OfflineSorter: Added guard clauses (and removed asserts).
Enabled nullable reference type support. Added disposed flag to ensure dispose
only happens once.
+- changes made for Redundant jump statements
[#684](https://github.com/apache/lucenenet/pull/684)
([#724](https://github.com/apache/lucenenet/pull/724))
+- Removed 2 private nested classes that were not in use
([#713](https://github.com/apache/lucenenet/pull/713))
+- Migrated all callers of `CharArraySet.UnmodifiableSet()` and
`CharArrayMap.UnmodifiableMap()` to the `AsReadOnly()` instance methods
+- Lucene.Net.Analysis.Common.Analysis.Util (CharArrayMap + CharArraySet):
Added `AsReadOnly()` instance methods to match .NET conventions and marked
UnmodifiableMap/UnmodifiableSet obsolete.
+- Removed call to `ToString()` for `StringBuilder.Append()` methods, so
strongly typed StringBuilder overloads can be used on target frameworks that
support it. Fixes [#668](https://github.com/apache/lucenenet/pull/668).
+- Lucene.Net.Benchmark.Support.TagSoup.HTMLScanner: Reworked initialization to
return `statetableIndexMaxChar` and set `statetableIndex` via out parameter.
+- Marked all singleton "Holder" classes static. Fixes
[#659](https://github.com/apache/lucenenet/pull/659).
+- Renamed classes from using Iterable and Iterator to Enumerable and
Enumerator, where appropriate - some were missed in
[#698](https://github.com/apache/lucenenet/pull/698).
+- Normalize anonymous class names/accessibility. Fixes
[#666](https://github.com/apache/lucenenet/pull/666).
+- Lucene.Net.Util.Fst.BytesStore: Suffix anonymous classes with
"AnonymousClass". See [#666](https://github.com/apache/lucenenet/pull/666).
+- Renamed classes from using Iterable and Iterator to Enumerable and
Enumerator, where appropropriate. See
[#279](https://github.com/apache/lucenenet/pull/279).
+- Add a nested comment explaining why this method is empty. Fixes
[#681](https://github.com/apache/lucenenet/pull/681).
+- Lucene.Net.Benchmark.Support.TagSoup: Reviewed API for accessibility issues.
Fixed error handling and guard clauses. Changed to generic collections. Renamed
method arguments.
+- Prefer 'AsSpan' over 'Substring' when span-based overloads are available.
Fixes [#675](https://github.com/apache/lucenenet/pull/675).
+- Lucene.Net.Analysis.Cn.Smart.Utility: Changed SPACES to use an encoded
character for `'\u3000'` so it is visible in the designer. Fixes
[#680](https://github.com/apache/lucenenet/pull/680).
+- Lucene.Net.Tests.Analysis.SmartCn.TestHMMChineseTokenizerFactory: Added
LuceneNetSpecificAttribute to `TestHHMMSegmenter()` and renamed
`TestHHMMSegmenterInitialization()`, since this is a smoke test that was added
to test initialization of HHMMSegmenter.
+- Increased timeouts on tests to keep them from intermittently failing during
nightly builds.
+- Ported missing test: TestIndexWriterOnJRECrash
([#786](https://github.com/apache/lucenenet/pull/786))

([#953](https://github.com/apache/lucenenet/pull/953))
+- TryDequeue and TryPeek Queue extension methods
([#957](https://github.com/apache/lucenenet/pull/957))
+- Renamed interface TokenAttribute type file names removing the prefix "I" so
the file it was ported from is clear.
+- Renamed concrete TokenAttribute type file names to be suffixed with "Impl"
so the file it was ported from is clear.
