Updates

  • A temporary work-around has been put in the VCF parser so that it is less likely to fail on rows with a large number of ALT alleles, where Number=G tags like PL can expand beyond the 2Gb limit enforced by HTSlib. For now, where this happens the offending tag will be dropped so the data can be processed, albeit without the likelihood data.
    In future work, the library will instead convert such tags into their local alternatives (see samtools/hts-specs#434).

  • New program. Adds annot-tsv which annotates regions in a destination file with texts from overlapping regions in a source file. (PR #1619)

  • Change bam_parse_cigar() so that it can modify existing BAM records. This makes more useful as public API. Previously it could only handle partially formed BAM records. (PR #1651, fixes #1650. Reported by Oleksii Nikolaienko)

  • Add "uncompressed" to hts_format_description() where appropriate. This adds an "uncompressed" description to uncompressed files that would normally be compressed, such as BAM and BCF. (PR #1656, in relation to samtools#1884. Thanks to John Marshall)

  • Speed up to the VCF parser and writer. (PR #1644 and PR #1663)

  • Add an hclen (hard clip length) SAM filter function. (PR #1660, with reference to #813)

  • Avoid really closing stdin/stdout in hclose()/hts_close()/et al. See discussion in PR for details. (PR #1665. Thanks to John Marshall)

  • Add support to handle multiple files in bgzip. (PR #1658, fixes #1642. Requested by bw2)

  • Enable auto-vectorisation in CRAM 3.1 codecs. Speeds decoding on some sequencing platform data. (PR #1669)

  • Speed up removal of lines in large headers. (PR #1662, fixes #1460. Reported by Anže Starič)

  • Apply seqtk PR to improve kseq.h parsing performance. Port of Fabian Klötzl's (kloetzl) lh3/seqtk#123 and attractivechaos/klib#173 to HTSlib. (PR #1674. Thanks to John Marshall)

Build changes

  • Updated htscodecs submodule to 1.6.0. (PR #1685, PR #1717, PR #1719)

  • Apply the packed attribute to uint*_u types for Clang to prevent -fsanitize=alignment failures. (PR #1667. Thanks to Fangrui Song)

  • Fuzz testing improvements. (PR #1664)

  • Add C++ casts for external headers in klist.h and kseq.h. (PR #1683. See also PR #1674 and PR #1682)

  • Add test case compiling the public headers as C++. (PR #1682. Thanks to John Marshall)

  • Enable optimisation level -O3 for SAM QUAL+33 formatting. (PR #1679)

  • Make compiler flag detection work with zig cc. (PR #1687)

  • Fix unused value warnings when built with NDEBUG. (PR #1688)

  • Remove some disused Makefile variables, fix typos and a warning. Improve bam_parse_basemod() documentation. (PR #1705, Thanks to John Marshall)

Bug fixes

  • Fail bgzf_useek() when offset is above block limits. (PR #1668)

  • Fix multi-threaded on-the-fly indexing problems. (PR #1672, fixes samtools#1861 and bcftools#1985. Reported by Mark Ebbert and lacek)

  • Fix hfile_libcurl small seek bug. (PR #1676, fixes samtools#1918. Also may fix #1037, #1625 and #1622. Reported by Alex Reynolds, Mark Walker, Arthur Gilly and skatragadda-nygc. Thanks to John Marshall)

  • Fix a minor memory leak in malformed CRAM EXTERNAL blocks. [fuzz] (PR #1671)

  • Fix a cram decode hang from block_resize(). (PR #1680. Reported by Sebastian Deorowicz)

  • Cram fuzzing improvements. Fixes a number of cram errors. (PR #1701, fixes #1691, #1692, #1693, #1696, #1697, #1698, #1699 and #1700. Thanks to Octavio Galland for finding and reporting all these)

  • Fix crypt4gh redirection. (PR #1675, fixes grbot/crypt4gh-tutorial#2. Reported by hth4)

  • Fix PG header linking when records make a loop. (PR #1702, fixes #1694. Reported by Octavio Galland)

  • Prevent issues with no-stored-sequence records in CRAM files, by ensuring they are accounted for properly in block size calculations, and by limiting the maximum query length in the CIGAR data. Originally seen as an overflow by OSS-Fuzz / UBSAN, it turned out this could lead to excessive time and memory use by HTSlib, and could result in it writing out unreadable CRAM files. (PR #1710)

  • Fix some illegal shifts and integer overflows found by OSS-Fuzz / UBSAN. (PR #1707, PR #1712, PR #1713)
