GNU Guix consists of Scheme code that implements the deployment model
of the Nix package management tool.  In fact, it currently talks to a
build daemon whose code comes from Nix (see the manual for details.)

Nix was initially written by Eelco Dolstra; other people have been
contributing to it.  See `nix/AUTHORS' for details.

The list of GNU Guix contributors is now generated from the output of
'git log' and written to this file, as can be seen in release tarballs.
ommit/tests/store-deduplication.scm?id=5a7cb59648d102168bd4ecd16f36b69e0f594be1'>deduplication: Detect holes and create sparse files....This reduces disk usage of sparse files that are substituted such as Guile object files (ELF files). As of Guile 3.0.9, .go files are sparse due to ELF sections being aligned on 64 KiB boundaries. This reduces disk usage reported by “du -sh” by 9% for the ‘guix’ package, by 23% for ‘guile’, and by 35% for ‘guile-git’. * guix/store/deduplication.scm (hole-size, find-holes): New procedures. (tee)[seekable?]: New variable. [read!]: Add case when SEEKABLE? is true. * tests/store-deduplication.scm (cartesian-product): New procedure. ("copy-file/deduplicate, sparse files (holes: ~a/~a/~a)"): New test set. Change-Id: Iad2ab7830dcb1220e2026f4a127a6c718afa8964 Ludovic Courtès 2022-12-10deduplicate: Use 'sendfile' for small file copies....* guix/store/deduplication.scm (dump-file/deduplicate): Use 'sendfile' instead of 'dump-port'. * tests/store-deduplication.scm ("copy-file/deduplicate, below %deduplication-minimum-size"): New test.
