Partly fixes <https://issues.guix.gnu.org/24937>. * config-daemon.ac: Remove symlink hard link check and CAN_LINK_SYMLINK definition. * guix/store/deduplication.scm (%deduplication-minimum-size): New variable. (deduplicate)[loop]: Do not recurse when FILE's size is below %DEDUPLICATION-MINIMUM-SIZE. (dump-port): New procedure. (dump-file/deduplicate)[hash]: Turn into... [dump-and-compute-hash]: ... this thunk. Call 'deduplicate' only when SIZE is greater than %DEDUPLICATION-MINIMUM-SIZE; otherwise call 'dump-port'. * nix/libstore/gc.cc (LocalStore::removeUnusedLinks): Drop files where st.st_size < deduplicationMinSize. * nix/libstore/local-store.hh (deduplicationMinSize): New declaration. * nix/libstore/optimise-store.cc (deduplicationMinSize): New variable. (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 2020-12-15nar: Deduplicate files right as they are restored....This avoids having to traverse and re-read the files that we have just restored, thereby reducing I/O. * guix/serialization.scm (dump-file): New procedure. (restore-file): Add #:dump-file parameter and honor it. * guix/store/deduplication.scm (tee, dump-file/deduplicate): New procedures. * guix/nar.scm (restore-one-item): Pass #:dump-file to 'restore-file'. (finalize-store-file): Pass #:deduplicate? #f to 'register-items'. * tests/nar.scm <top level>: Call 'setenv' to set "NIX_STORE". Ludovic Courtès 2020-12-15serialization: 'restore-file' sets canonical timestamp and permissions....* guix/serialization.scm (restore-file): Set the permissions and mtime of FILE. * guix/nar.scm (finalize-store-file): Pass #:reset-timestamps? #f to 'register-items'. * tests/nar.scm (rm-rf): Add 'chmod' calls to ensure files are writable. ("write-file + restore-file with symlinks"): Ensure every file in OUTPUT passes 'canonical-file?'. * tests/guix-archive.sh: Run "chmod -R +w" before "rm -rf". Ludovic Courtès 2020-12-15serialization: 'fold-archive' notifies about directory processing completion....* guix/serialization.scm (fold-archive): Call PROC with a 'directory-complete tag when done with a directory. (restore-file): Handle it. * guix/scripts/archive.scm (list-contents): Likewise. * guix/scripts/challenge.scm (archive-contents): Likewise. * tests/nar.scm ("write-file-tree + fold-archive"): Adjust accordingly.
