Co-authored-by: Ludovic Courtès <ludo@gnu.org> Antero Mejr 2022-04-04packages: Add 'package-unique-version-prefix'....* gnu/packages.scm (package-unique-version-prefix): New procedure. * guix/scripts/package.scm (manifest-entry-version-prefix): Use it. * tests/packages.scm ("package-unique-version-prefix, gcc@8") ("package-unique-version-prefix, grep"): New tests. Ludovic Courtès 2022-01-11shell: Cache profiles even when using package specs....This enables profile caching not just when '-m' or '-f' is used, but also when package specs are passed on the command line, as in: guix shell -D guix git It also changes profile cache keys to include the system type, which was previously ignored. * guix/scripts/shell.scm (options-with-caching)[single-file-for-caching]: Remove. Call 'profile-cached-gc-root' instead; adjust to accept two values. (profile-cache-primary-key): New procedure. (profile-cache-key): Remove. (profile-file-cache-key, profile-spec-cache-key): New procedures. (profile-cached-gc-root): Rewrite to include functionality formally in 'single-file-for-caching', but extend to handle package specs. * gnu/packages.scm (cache-is-authoritative?): Export. * guix/transformations.scm (transformation-option-key?): New procedure. * doc/guix.texi (Invoking guix shell): Move '--rebuild-cache' documentation to the bottom, just above '--root'. Explain caching and how these two options relate to that. Ludovic Courtès 2020-07-30packages: 'generate-package-cache' is deterministic....Fixes <https://bugs.gnu.org/42009>.
