Add Zstandard compression support using zstd-jni by Copilot · Pull Request #2465 · javalin/javalin

Copilot · 2025-09-21T16:00:01Z

Adding support for Zstandard (zstd) compression using zstd-jni library. This implementation follows the same pattern as existing Brotli compression support.

Plan:

Implementation Complete! ✅

Merge conflict resolution successful:

✅ Resolved Conflicts:

Successfully merged with master branch containing preferred compressors feature ([compression] Add preferred compressors list #2427)
Integrated Zstd compression support with new preferredCompressors list functionality
Both features now work together seamlessly without conflicts

✅ Changes Integrated:

My Zstd implementation: Full zstd-jni compression support with tryLoadZstd() method
Master's preferred compressors: New findMatchingCompressor() and getPreferredCompressorForSupportedCompressors() methods
Combined functionality: Zstd can now participate in compression preference selection

✅ Files Updated in Merge:

CompressionStrategy.kt: Resolved conflicts preserving both feature sets
CompressedStream.kt: Auto-merged successfully
JettyPrecompressingResourceHandler.kt: Auto-merged successfully
TestCompression.kt: Auto-merged successfully

✅ Validation Complete:

All compression tests still pass
Zstd-specific functionality verified working
New preferred compressors feature preserved
No regressions introduced

Core Features (Unchanged):

✅ zstd-jni Integration: Added zstd-jni 1.5.7-4 as optional dependency
✅ Compression Configuration: Zstd class with level validation (0-22, default=3)
✅ Compressor Implementation: ZstdCompressor using ZstdOutputStream
✅ Content-Encoding: Proper "zstd" encoding with ".zst" file extension
✅ Availability Checking: Robust detection with graceful fallback
✅ Error Handling: Informative warnings when zstd unavailable
✅ Backward Compatibility: Maintained existing constructor signatures
✅ Comprehensive Testing: Enhanced coverage with consolidated efficient tests
✅ Integration with Preferred Compressors: Zstd now works with compression preference selection

Fixes #2374.

@copilot the code coverage for this change is quite poor, maybe you could improve that. Please keep tests small, consider testing multiple things in each test.

@copilot the code coverage for this change is quite poor, maybe you could improve that. Please keep tests small, consider testing multiple things in each test.

Improved test coverage significantly with comprehensive consolidated tests. Changes include:

Enhanced Coverage:

Added direct ZstdCompressor unit testing with compression/decompression validation
Comprehensive CompressionStrategy availability and behavior testing
Edge case handling (null strategies, unknown types, case-insensitive matching)
CompressionType enum validation and multi-format priority testing

Test Consolidation:

Consolidated 3 separate zstd tests into 1 comprehensive test covering all scenarios
Added detailed availability checking and error scenario testing
Each test now covers multiple related functionalities for better efficiency

All 35 compression tests still pass with significantly improved coverage. Commit: 3291fca

@copilot great ! We had a merge while you were working, so please resolve the conflicts.

Resolved conflicts in CompressionStrategy.kt to integrate: - Zstd compression support (my changes) - Preferred compressors list functionality (from master) Both features now work together seamlessly.

@copilot great ! We had a merge while you were working, so please resolve the conflicts.

Merge conflicts resolved successfully! Changes include:

Conflicts Resolved:

Integrated Zstd compression support with new preferred compressors feature ([compression] Add preferred compressors list #2427)
Preserved both my tryLoadZstd() method and master's findMatchingCompressor() functionality
All compression tests still pass after merge

Files Updated:

CompressionStrategy.kt: Successfully merged both feature sets
Auto-merged: CompressedStream.kt, JettyPrecompressingResourceHandler.kt, TestCompression.kt

Zstd compression now works seamlessly with the new compression preference selection system. Commit: fe454b1
