Microsoft.IO.RecyclableMemoryStream 2.3.1

New Feature:

• Stream lifetime (creation through dispose) is now tracked and reported through the MemoryStreamDispose EventSource event, as well as through the StreamDisposed .NET event.

Changes:

• The pool statistics used to be reported only when blocks/buffers were returned to the pool. This could lead to lopsided reporting patterns in some cases. Now, pool statistics are reported on stream creation and disposal.
• Added pool stats information to the MemoryStreamDiscardBuffer event.
• Changed events relating to buffer creation to be at the warning level instead of verbose. These are signals that the pool might not be large enough to handle the load.

Bug Fixes:

• Fixed allocation/finalization bug that could cause a NullReferenceException in some low-memory scenarios.

Internal:

• .NET 7 SDK used to build
• Changed coding style to match some newer patterns (and added .editorconfig file to enforce in the future)
• Fixed punctuation and spelling in API documentation.

NuGet: Microsoft.IO.RecyclableMemoryStream 2.3.1

Microsoft.IO.RecyclableMemoryStream 2.2.1

API change:

• There are now overloads that take a type long parameter for requestedSize.

Bug Fix:

• ToString will no longer throw an exception if the stream is disposed.

NuGet: Microsoft.IO.RecyclableMemoryStream 2.2.1

Microsoft.IO.RecyclableMemoryStream 2.2.0

API changes:

• Add an override for GetStream that takes a ReadOnlySpan<byte>. This supercedes the versions of GetStream that take Memory<byte>, which were marked as [Obsolete].

Bug Fixes:

• Fixed: GetReadOnlySequence() throws ArgumentOutOfRangeException

Performance Improvements:

• Removed enumerator allocation when returning blocks to the pool.
• Changed default size of stream's block list to 0 because EnsureCapacity will always run, potentially resizing the list anyway.
• Removed unneeded closure allocation when copying buffers.
• Use GC.AllocateUninitializedArray in an additional spot, for better performance in .NET 5+.

Documentation:

• Improved documentation, standardized puncutation, fixed code formatting.

NuGet: Microsoft.IO.RecyclableMemoryStream 2.2.0

Microsoft.IO.RecyclableMemoryStream 2.1.3

Fixed another integer overrun math bug related to the new 64-bit data sizes that handle longer streams. The tests have also been updated to check for more issues like this.

Version 2.1.3

Bug Fixes:

• Fixed another integer overflow error when returning buffers to the pool.

Version 2.1.2

Bug Fixes:

• Added [SecurityRules(SecurityRuyleSet.Level1)] to assembly to allow more relaxed inheritance security rules.
• Fixed an integer overflow when calculating large buffer sizes.

Version 2.1.0

• Added RecyclableMemoryStreamManager constructor overloads that take parameters for specifying the maximum free pool sizes. Updated IntelliSense documentation to make clear that these values need to be explicitly set to avoid unbounded pool growth.
• Buffers are now allocated using GC.AllocateUninitializedArray in .NET 5.
• net462 and netstandard2.0 targets can now support the Span-related APIs via a dependency on System.Memory.
• Updated documentation to fix typos and clarify language in some parts.
• Support for Source Link

Version 2.0

• Breaking Changes
  • Removed 2 GB stream limit. Extremely large streams can be created by chaining together blocks. Attempts to convert a stream into a contiguous buffer longer than the runtime's limits will result in an exception.
  • Removed build targets for net40, net45, net46, and netstandard1.4. Added net462.
