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
2021-10-28store: 'map/accumulate-builds' handler checks the store received....This is a followup to b19250eec6f92308f237a09a43e8e3e2355345b9, providing a proper fix for <https://issues.guix.gnu.org/46756>. * guix/remote.scm (remote-eval): Revert b19250eec6f92308f237a09a43e8e3e2355345b9. * guix/store.scm (build-accumulator): Turn into a procedure. Call CONTINUE when the store is not eq? to the initial store. (map/accumulate-builds): Adjust accordingly. * tests/store.scm ("map/accumulate-builds and different store"): New test. Ludovic Courtès
2021-09-15store: 'map/accumulate-builds' processes the whole list in case of cutoff....Fixes <https://issues.guix.gnu.org/50264>. Reported by Lars-Dominik Braun <lars@6xq.net>. This fixes a regression introduced in fa81971cbae85b39183ccf8f51e8d96ac88fb4ac whereby 'map/accumulate-builds' would return REST (the tail of LST) without applying PROC on it. The effect would be that 'lower-inputs' in (guix gexp) would dismiss those elements, leading to derivations with correct builders but only a subset of the inputs they should have had. * guix/store.scm (map/accumulate-builds): Add #:cutoff parameter and remove 'accumulation-cutoff' variable. Call PROC on the elements of REST. * tests/store.scm ("map/accumulate-builds cutoff"): New test. Ludovic Courtès
2021-06-08store: Remove 'references/substitutes'....This procedure lost its only user in commit 710854304b1ab29332edcb76f3de532e0724c197. * guix/store.scm (references/substitutes): Remove. * tests/store.scm ("references/substitutes missing reference info") ("references/substitutes with substitute info"): Remove.
