2026-07-31scripts/sbom: catch ValueError from malformed shell quotingCarlos Sampaio Ribeiro
parse_inputs_from_commands() only caught CmdParsingError and IndexError when dispatching to command parsers, but several parsers call shlex.split() internally, which raises ValueError on malformed shell quoting (e.g. an unterminated quote). This exception was not caught, so a single malformed build command would abort SBOM generation entirely, even with fail_on_unknown_build_command=False, defeating the purpose of tolerant mode. The issue was found while reviewing the exception handling around the saved-command parser after running its existing tests. It can be reproduced with: parse_inputs_from_commands('gcc "unterminated', fail_on_unknown_build_command=False) Catch ValueError alongside CmdParsingError and IndexError so such commands are logged as a warning/error and skipped instead of aborting the whole run. Add tests covering malformed shell quoting and a missing positional argument.

2026-05-22scripts/sbom: add JSON-LD serializationLuis Augenstein
Add infrastructure to serialize an SPDX graph as a JSON-LD document. NamespaceMaps in the SPDX document are converted to custom prefixes in the @context field of the JSON-LD output. The SBOM tool uses NamespaceMaps solely to shorten SPDX IDs, avoiding repetition of full namespace URIs by using short prefixes.
