Module Name: baselibs
Release Tag: v0.2.13
Origin Release Tag: v0.2.12
Release Commit Hash: e7ddf3b
Release Date: 2026-09-17

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.

Notable Changes

Breaking changes & deprecations

• score/datetime_converter has been removed, completing its deprecation in v0.2.11. Use POSIX or C library time APIs where equivalent functionality is required. #471
• The unused score/os's cpuid, file_stream, and make_dev libraries, tests, and mocks have been removed. #535

Coverage reporting migration

• The LLVM source-based coverage migration announced in v0.2.12 is complete. bazel coverage --config=llvm_cov now produces one report for C++ and Rust, including line and branch data and 0% baselines for untested in-scope files. The pipeline is now supplied by score_coverage 0.2.0, which corrects source attribution and report links. #533 #584 #589

New features

• Rust applications can use a wrapper around score::cpp::stop_token, enabling integration with frameworks that require stop tokens, such as lifecycle. #461
• LockedPtr now provides the monadic transform and and_then operations for composing work on locked values. #456 #458
• FlatBuffers JSON-schema generation now post-processes flatc output to restore rich attributes from schema-comment tokens, such as @title, and orders generated attributes deterministically. #474
• The OS abstraction now implements setenv and unsetenv, and the score/os:netdb Bazel target is publicly available. #507 #535

Bug fixes

• score::os::StatBuffer now represents user and group IDs as unsigned 64-bit values, and FileUtils::ValidateGroup uses a matching conversion when comparing group IDs. #563

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
