| 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.

* Sun May 28 2023 Dirk Müller <dmueller@suse.com>
- 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.
* Tue Feb 21 2023 Martin Hauke <mardnh@gmx.de>
- Update to version 5.4.1
Bugfixes:
* fix random char value of UTF-8.
* bypass logical combination flag in hs_expression_info().
* fix build error due to libc symbol parsing.
* add empty string check for pure literal API.
* fix unknown instruction error in pure literal API.
* avoid memory leak in stream close stage.
* fix assertion failure in DFA construction.

- BuildRequire python3-base instead of python(2), it used py3 already
anyway
* Wed Jan 13 2021 Martin Hauke <mardnh@gmx.de>

* Bugfix for issue #284: use correct free function in logical
combination.
* Add BUILD_EXAMPLES cmake option to enable example code
compilation.
* Some typo fixing.
* Mon May 25 2020 Martin Hauke <mardnh@gmx.de>
- Update to version 5.3.0

with clang and ASAN.
* Bugfix for issue #217: fix cmake parsing issue of CPU arch for
non-English locale.
* Bugfix for issue #228: avoid undefined behavior when calling
close() after fdopendir() in loadExpressions().

- 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 <mardnh@gmx.de>
- Update to version 5.1.1
* Add extra detection and handling when invalid rose programs are
triggered.
* 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 mardnh@gmx.de
- 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 mardnh@gmx.de
- Add patch
* hyperscan-build.patch (fix build for Tumbleweed)
* Tue Jul 10 2018 mardnh@gmx.de
- 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
now available on Windows 8 or newer.
* Improve undirected graph implementation to avoid graph copy and
reduce compile time.
* Bugfix for issue #86: enable hscollider for installed PCRE
package.
