2021-11-16daemon: Do not deduplicate files smaller than 8 KiB....Files smaller than 8 KiB typically represent ~70% of the entries in /gnu/store/.links but only contribute to ~4% of the space savings afforded by deduplication. Not considering these files for deduplication speeds up file insertion in the store and, more importantly, leaves 'removeUnusedLinks' with fewer entries to traverse, thereby speeding it up proportionally.

(LocalStore::optimisePath_): Return when PATH is a symlink or smaller than 'deduplicationMinSize'. * tests/derivations.scm ("identical files are deduplicated"): Produce files bigger than %DEDUPLICATION-MINIMUM-SIZE. * tests/nar.scm ("restore-file-set with directories (signed, valid)"): Likewise. * tests/store-deduplication.scm ("deduplicate, below %deduplication-minimum-size"): New test. ("deduplicate", "deduplicate, ENOSPC"): Produce files bigger than %DEDUPLICATION-MINIMUM-SIZE. * tests/store.scm ("substitute, deduplication"): Likewise. Ludovic Courtès

2021-11-16build-system/julia: Enable Julia Pkg to find installed packages....Julia's built-in package manager (Pkg) looks for packages in JULIA_DEPOT_PATH/packages/PACKAGENAME/XXXX, where XXXX is a string encoding package UUID and SHA1 of files.
