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. 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.

2019-11-27daemon: GC remove-unused-links phase uses 'statx' when available....* config-daemon.ac: Check for 'statx'. * nix/libstore/gc.cc (LocalStore::removeUnusedLinks) [HAVE_STATX]: Use 'statx' instead of 'lstat'. Ludovic Courtès
2019-11-13daemon: Don't include <linux/fs.h>....As of GNU libc 2.29, <sys/mount.h> declares all the constants and functions we need, so there's no use in including <linux/fs.h> anymore. This silences annoying warnings like this one: In file included from nix/libstore/local-store.cc:32:0: /gnu/store/…-linux-libre-headers-4.19.56/include/linux/fs.h:108:0: warning: "MS_RDONLY" redefined #define MS_RDONLY 1 /* Mount read-only */ In file included from nix/libstore/local-store.cc:28:0: /gnu/store/…-glibc-2.29/include/sys/mount.h:36:0: note: this is the location of the previous definition #define MS_RDONLY MS_RDONLY * config-daemon.ac: Remove check for <linux/fs.h>. * nix/libstore/build.cc: Remove conditional inclusion of <linux/fs.h>. * nix/libstore/local-store.cc: Remove "#if HAVE_LINUX_FS_H" and inclusion of <linux/fs.h>.

(SubstitutionGoal::tryToRun): Adjust to run 'guix substitute' via 'settings.guixProgram'. (SubstitutionGoal::finished): Call 'amDone(ecFailed)' upon failure instead of setting 'state' to 'tryNext'. * nix/libstore/globals.hh (Settings)[substituters]: Remove. * nix/libstore/local-store.cc (LocalStore::~LocalStore): Adjust to handle a single substituter. (LocalStore::startSubstituter): Remove 'path' parameter. Adjust to invoke 'settings.guixProgram'. Don't refer to 'run.program', which no longer exists.
