Name: libhs5 Distribution: openSUSE Tumbleweed
Version: 5.4.2 Vendor: openSUSE
Release: 1.4 Build date: Sun May 28 11:29:08 2023
Group: System/Libraries Build host: reproducible
Size: 13643527 Source RPM: hyperscan-5.4.2-1.4.src.rpm
Summary: Regular expression matching library
Hyperscan is a multiple regex matching library. It
follows the regular expression syntax of the commonly-used libpcre
library, but is a standalone library with its own C API.

Hyperscan uses hybrid automata techniques to allow simultaneous
matching of large numbers (up to tens of thousands) of regular
expressions and for the matching of regular expressions across streams
of data.

Hyperscan is typically used in a DPI library stack.

  - update to 5.4.2:
    * Roll back bugfix for github issue #350: Besides using scratch
      for corresponding database, Hyperscan also allows user to use
      larger scratch allocated for another database. Users can
      leverage this property to achieve safe scratch usage in
      multi-database scenarios. Behaviors beyond these are
      discouraged and results are undefined.
    * Fix hsdump issue due to invalid nfa type.

      including support for Intel(R) Advanced Vector Extensions 512
      (Intel(R) AVX-512).
    * hsbench: add hyphen support for -T option.
    * tools/fuzz: add test scripts for synthetic pattern generation.

* Wed Oct 30 2019 Martin Hauke <>
  - Update to version 5.2.1
    - Fix compile issue when `BUILD_SHARED_LIBS` is on in
      release mode.
  - Update to version 5.2.0
    - Literal API: add new API `hs_compile_lit()` and
      `hs_compile_lit_multi()` to process pure literal rule sets.
      The 2 literal APIs treat each expression text in a literal
      sense without recognizing any regular grammers.
    - Logical combination: add support for purely negative
      combinations, which report match at EOD in case of no
      sub-expressions matched.
    - Fix uninitialized use of `scatter_unit_uX` due to padding.
    - Fix numerical result out of range error.
    - Avoid corruption of pending combination report in streaming mode.
    - Fix scratch free issue when memory allocation fails.
  - Builds are broken with LTO - disable for for now
* Wed Apr 10 2019 Martin Hauke <>
  - Update to version 5.1.1
    * Add extra detection and handling when invalid rose programs are
    * Fix CMake parsing of CPU architecure for GCC-9.
    * Fix rose literal programs for multi-pattern matching when no
      pattern ids are provided.
    * Fix library install path in pkg-config files.
* Thu Jan 31 2019
  - Update to version 5.1.0
    * Improve DFA state compression by wide-state optimization to
      reduce bytecode size.
    * Create specific interpreter runtime handling to boost the
      performance of pure literal matching.
    * Optimize original presentation of interpreter (the "Rose"
      engine ) to increase overall performance.
    * Bugfix for logical combinations: fix error reporting
      combination's match in case of sub-expression has EOD match
      under streaming mode.
    * Bugfix for logical combinations: fix miss reporting
      combination's match under vacuous input.
    * Fix compile error with Boost 1.68.0.
    * avoid pcre error for hscollider with installed PCRE package.
    * Update version of PCRE used by testing tools as a syntax and
      semantic reference to PCRE 8.41 or above.
  - Remove patch:
    * hyperscan-build.patch (fixed upstream)
* Tue Sep 25 2018
  - Add patch
    * hyperscan-build.patch (fix build for Tumbleweed)
* Tue Jul 10 2018
  - Update to version 5.0.0
    * Introduce chimera hybrid engine of Hyperscan and PCRE, to fully
      support PCRE syntax as well as to take advantage of the high
      performance nature of Hyperscan.
    * New API feature: logical combinations (AND, OR and NOT) of
      patterns in a given pattern set.
    * Windows porting: hsbench, hscheck, hscollider and hsdump tools
