…K-031) - Add ChunkIterator type with Next/Chunk/Err pattern (like bufio.Scanner) - Add ChunkIteratorWithContext for cancellation support - Add progress callbacks and reset functionality - Fix B-tree key format to include nbytes field (HDF5 spec compliance) - Fix chunked writer to update B-tree address in layout message - Update README.md and CHANGELOG.md with new feature
LZF (ID 32000): Pure Go read+write, h5py/PyTables compatible BZIP2 (ID 307): stdlib read, write stub SZIP (ID 4): stub with descriptive errors (requires libaec)
Both CVEs confirmed NOT AFFECTED: - CVE-2025-2309 (bitfield): data conversion not implemented - CVE-2025-2308 (scale-offset): filter not implemented Updated feature parity for LZF/BZIP2/SZIP filters.
- Handle uncompressed data when compression doesn't help (size == expected) - Pad output with zeros when decompressed size < expected (sparse chunks) - Add empty data check in applyLZF Tested with h5ex_d_lzf.h5 - now reads correctly.
