URL: https://github.com/apache/doris/pull/55245
Currently, Doris bundles and uses an older version of vectorscan (a fork of
HyperScan optimized for SIMD). To address known bugs, support risc-v, improve
stability, support risc-v,and gain performance benefits, it is necessary to
upgrade this dependency to the latest release version.
Proposal
Update the bundled vectorscan library from its current version to 5.4.12.
Reason for Change
This upgrade brings a multitude of fixes and optimizations, most notably:
Performance Improvement: Utilizes 256-bit TBL instructions to significantly
speed up the truffle instruction.
Critical Bugfixes: Resolves several severe issues that could lead to
incorrect results or runtime failures, including:
Fixes a potential failure in partial_load_u64 when handling zero-length
buffers.
Corrects an out-of-bounds read in the AVX512VBMI implementation of
fdr_exec_fat_teddy.
Fixes an off-by-one error in the SVE2 noodle implementation.
Allows patterns that start with a null character (\0), improving
compatibility.
Resolves a false positive issue at the end of a vector in the double
shufti algorithm.
Fixes regressions related to AVX512VBMI.
System & Compatibility:
Fixes the SSE4.2 platform check in hs_valid_platform.
Resolves a regression in the configuration step that was introduced in
version 5.4.11.
Removes build warnings related to Clang 17+ and Boost on macOS.
Adds the missing hs_version.h header file.
Addresses various Clang Tidy warnings, improving code quality.
