(N for software_File, N for hasDeclaredLicense's Relationship) For large numbers of source files, adding an extra symlink -> real file will occupy one more inode (per file), which will need a slot in the OS's inode cache. In this situation, disk performance is slow and inode is used up quickly After commit [sbom30/spdx30: add link prefix and name to namespace of spdxId and alias] applied, the namespace of spdxId and alias in recipe and package jsonld differs. Use it to create symlink to jsonld, take recipe shadow, package shadow and package shadow-src for example: For recipe jsonld tmp/deploy/spdx/3.0.1/core2-64/recipes/shadow.spdx.json spdxId: http://spdx.org/spdxdocs/recipe-shadow-xxx/... alias: http://spdx.org/spdxdocs/openembedded-alias/recipe-shadow/UNIHASH/... link-name: recipe-shadow symlink: tmp/deploy/spdx/3.0.1/core2-64/by-spdxid-link/recipe-shadow.spdx.json -> ../recipes/shadow.spdx.json For package jsonld tmp/deploy/spdx/3.0.1/core2-64/packages/shadow.spdx.json spdxId: http://spdx.org/spdxdocs/package-shadow-xxx/... alias: http://spdx.org/spdxdocs/openembedded-alias/package-shadow/UNIHASH/... link-name: package-shadow symlink: tmp/deploy/spdx/3.0.1/core2-64/by-spdxid-link/package-shadow.spdx.json -> ../packages/shadow.spdx.json In package jsonld tmp/deploy/spdx/3.0.1/core2-64/packages/shadow-src.spdx.json spdxId: http://spdx.org/spdxdocs/package-shadow-src-xxx/... alias: http://spdx.org/spdxdocs/openembedded-alias/package-shadow-src/UNIHASH/... link-name: package-shadow-src symlink: tmp/deploy/spdx/3.0.1/core2-64/by-spdxid-link/package-shadow-src.spdx.json -> ../packages/shadow-src.spdx.json Build core-image-minimal with/without this commit, comparing the spdxid-link number, 7 281 824 -> 6 043 echo 'SPDX_INCLUDE_SOURCES = "1"' >> local.conf Without this commit: $ time bitbake core-image-minimal real 100m17.769s user 0m24.516s sys 0m4.334s $ find tmp/deploy/spdx/3.0.1/*/by-spdxid-hash -name "*.json" |wc -l 7281824 With this commit: $ time bitbake core-image-minimal real 85m12.994s user 0m20.423s sys 0m4.228s $ find tmp/deploy/spdx/3.0.1/*/by-spdxid-link -name "*.json" |wc -l 6043 Signed-off-by: Hongxu Jia <hongxu.jia@windriver.com> commit 0523e946e618537edf13789c0a4e10741e59fb38 Author: Hongxu Jia <hongxu.jia@windriver.com> Date: Sun Nov 24 21:44:07 2024 -0800 sbom30/spdx30: add link prefix to the namespace of spdxId and alias In order to simple reference the SPDX ID to instead of making jsonld hash path for each element, only creating one symlink for one file and referencing it multiple times, add link prefix and name to the namespace of spdxId and alias to replace ${PN} to avoid namespace conflict between recipe, packages and images. Take recipe shadow, package shadow and package shadow-src for example: Without this commit, spdxId and alias in recipe and package jsonld have the same namespace spdxId: http://spdx.org/spdxdocs/shadow-xxx/... alias: http://spdx.org/spdxdocs/openembedded-alias/shadow/UNIHASH/... After apply this commit, the namespace of spdxId in recipe and package jsonld differs: In recipe jsonld tmp/deploy/spdx/3.0.1/core2-64/recipes/shadow.spdx.json spdxId: http://spdx.org/spdxdocs/recipe-shadow-xxx/... alias: http://spdx.org/spdxdocs/openembedded-alias/recipe-shadow/UNIHASH/...
