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. 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 2021-06-18Start enabling substitutes from bordeaux.guix.gnu.org....In addition to substitutes from ci.guix.gnu.org. There are more changes that can be made in the future, but these changes seem like a good start. * config-daemon.ac (guix_substitute_urls): Add https://bordeaux.guix.gnu.org. * guix/scripts/substitute.scm (%default-substitute-urls): Add http://bordeaux.guix.gnu.org. * guix/store.scm (%default-substitute-urls): Add bordeaux.guix.gnu.org. * doc/guix.texi: Adjust accordingly. * doc/contributing.texi: Adjust accordingly. Christopher Baines 2020-12-11maint: Remove unused 'NIX_VERSION' macro....* config-daemon.ac: Do not define NIX_VERSION. Ludovic Courtès 2020-12-11maint: Avoid macros obsolete in Autoconf 2.70....* configure.ac: Require Autoconf 2.69. Use 'AS_HELP_STRING' instead of 'AC_HELP_STRING'. * m4/guix.m4: Likewise. * config-daemon.ac: Use 'AC_CONFIG_HEADERS' instead of the singular variant. Ludovic Courtès
