Module Name: baselibs
Release Tag: v0.2.18
Origin Release Tag: v0.2.17
Release Commit Hash: 0a80b55
Release Date: 2026-11-12

Overview

The baselibs module provides a selection of basic C++ utility libraries for common use in the S-CORE project.

Disclaimer

This release is not intended for production use, as it does not include a safety argumentation or a completed safety assessment.
The work products compiled in the safety package are created with care according to the S-CORE process (https://eclipse-score.github.io/process_description/main/index.html). However, as a non-profit, open-source organization, the project cannot assume any liability for its content.

For details on the features, see https://eclipse-score.github.io/score/main/features/baselibs/index.html

Notable Changes

Breaking changes & deprecations

  • Hash (score/hash): Removed SHA-1 support, including its public API, hash identification, calculator factories, and OpenSSL wrapper. The former SHA-1 identifier is no longer accepted. Use a supported alternative such as SHA-256. #765
  • JSON (score/json): JsonParser now rejects duplicate member names within an object with Error::kParsingError, instead of silently dropping values or merging duplicate containers. Inputs with duplicate names that previously parsed now fail. #785
  • Serialization (score/serialization): Added a 16-level limit to nested struct field traversal; exceeding it triggers an assertion. #775

New features

  • Serialization (score/serialization): Extended strategy support with nested field paths and per-level last-element metadata, SerializeIterator::WriteAt for back-patching already-written data, and DeSerializeIterator::SetError for reporting strategy-detected errors. Added SerializationError::kDeserializedCountExceedsCapacity. #775

Bug fixes

  • Serialization (score/serialization): Writing into a full static_vector output buffer now returns kOutOfBoundsWrite instead of triggering an assertion. Corrected iterator byte counts, made DeSerializeIterator postfix increment return the previous position, and made End() constant-time. #741
  • Serialization (score/serialization): UDS deserialization now clears reused string/vector destinations instead of appending to their contents. It stops on truncated length-prefixed data or vector elements that consume no input, and struct-field traversal stops after a latched failure. #741
  • JSON (score/json): Fixed Any numeric conversions for values constructed in code: float to double now widens instead of aborting, and NaN-to-integer conversion returns kWrongType instead of reaching an undefined conversion. Parsed JSON is unaffected by these fixes. #790

Compatibility

The following platforms are supported using the bazel_cpp_toolchains (https://github.com/eclipse-score/bazel_cpp_toolchains):

  • x86_64-unknown-linux-gnu
  • aarch64-unknown-linux-gnu
  • x86_64-unknown-nto-qnx800
  • aarch64-unknown-nto-qnx800

Performed Verification

  • Build on all supported platforms
  • Unit test execution on all supported platforms (some test failures are expected on AArch64 and QNX targets).
  • Address and undefined behavior sanitized unit test execution
  • Leak sanitized unit test execution

Report: https://github.com/eclipse-score/baselibs/actions/runs/43199620732

Upgrade Instructions

Backward compatibility with the previous release is not guaranteed.
