NightOwl888 opened a new pull request, #725: URL: https://github.com/apache/lucenenet/pull/725
- `Lucene.Net.Document.CompressionTools::CompressString()`: Eliminated unnecessary `ToCharArray()` allocation - `Lucene.Net.Codecs.SimpleText.SimpleTextUtil::Write()`: Removed unnecessary `ToCharArray()` allocation - `Lucene.Net.Analysis.CharFilters.HTMLStripCharFilter`: Removed allocation during parse of hexadecimal integers by using `J2N.Numerics.Int32.TryParse()` overloads to specify index, length and radix. - Added a `CharArrayFormatter` struct to defer the allocation of constructing a string for `Debugging.Assert()` until after an assertion failure. - Added `maxStackByteLimit` system property that can be used to increase/decrease the stack threshold bytes where it switches to the heap. - `StemmerOverrideFilter.Builder` - Added overloads of `Add()` for `char[]` and `ICharSequence`. Added guard clauses. Modified to use `Span<char>` on the stack when under the `maxStackByteLimit` setting. - `Lucene.Net.Util.UnicodeUtil`: Added an overload of `UTF16toUTF8()` for `Span<T>` source to `BytesRef` destination. Added documentation and guard clauses. Renamed `s` parameter to `source` to be consistent across all overloads. - `Lucene.Net.Analysis.Util.CharacterUtils`: Use spans and stackalloc to reduce heap allocations when lowercasing. - `Lucene.Net.Util.TestUnicodeUtil::TestUTF8toUTF32()`: Added tests for `ICharSequence` and `char[]` overloads, changed the original test to test `string` instead of `char[]`. - `Lucene.Net.Analysis.Util.SegmentingTokenizerBase`: Removed unnecessary string allocations that were added during the port due to missing APIs that are now available. - `Lucene.Net.Analysis.Ja.GraphvizFormatter`: Removed unnecessary `surfaceForm` variable string allocation. - `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.In.IndicNormalizer`: Refactored `ScriptData` from using `Dictionary<Regex, ScriptData>` to using `List<ScriptData>` which eliminated unnecessary hashtable lookup. Use static fields for `unknownScript` and `[ThreadStatic] previousScriptData` to cache the last script seen to optimize character script matching. - `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, since the latter doesn't require converting to a string to detect a match. - `Lucene.Net.Analysis.Ga.IrishLowerCaseFilter`: Use stack and spans to reduce allocations and improve throughput. -- This is an automated message from the Apache Git Service.
