2021-11-16daemon: Do not deduplicate files smaller than 8 KiB.Ludovic Courtès
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.

2017-03-08hash: Close or flush sha256 output ports before calling their 'get' procedure.Ludovic Courtès
Slightly different buffering of custom binary output ports in Guile 2.1.7 would lead tests missing 'close-port' or 'force-output' to fail. * tests/hash.scm ("open-sha256-port, hello"): Add call to 'force-output' before call to 'get'. * tests/nar.scm ("write-file puts file in C locale collation order"): Call 'close-port' before calling 'get-hash'.

2016-04-03build: Add a Guile custom test driver using SRFI-64.Mathieu Lirzin
Before that '.log' files for scheme tests were fragmented and not included in test-suite.log. This unifies the semantics of SRFI-64 API with Automake test suite. * build-aux/test-driver.scm: New file. * Makefile.am (SCM_LOG_DRIVER, AM_SCM_LOG_DRIVER_FLAGS): New variables. (SCM_LOG_COMPILER, AM_SCM_LOG_FLAGS): Delete variables. (AM_TESTS_ENVIRONMENT): Set GUILE_AUTO_COMPILE to 0. * test-env.in: Silence guix-daemon. * doc/guix.texi (Running the Test Suite): Describe how to display the detailed results. Bug reports require only 'test-suite.log' file. * tests/base32.scm, tests/build-utils.scm, tests/builders.scm, tests/challenge.scm, tests/cpan.scm, tests/cpio.scm, tests/cran.scm, tests/cve.scm, tests/derivations.scm, tests/elpa.scm, tests/file-systems.scm, tests/gem.scm, tests/gexp.scm, tests/gnu-maintenance.scm, tests/grafts.scm, tests/graph.scm, tests/gremlin.scm, tests/hackage.scm, tests/hash.scm, tests/import-utils.scm, tests/lint.scm, tests/monads.scm, tests/nar.scm, tests/packages.scm, tests/pk-crypto.scm, tests/pki.scm, tests/profiles.scm, tests/publish.scm, tests/pypi.scm, tests/records.scm, tests/scripts-build.scm, tests/scripts.scm, tests/services.scm, tests/sets.scm, tests/size.scm, tests/snix.scm, tests/store.scm, tests/substitute.scm, tests/syscalls.scm, tests/system.scm, tests/ui.scm, tests/union.scm, tests/upstream.scm, tests/utils.scm: Don't exit at the end of test groups. * tests/containers.scm: Likewise.

2015-08-26tests: Work around Btrfs handling of nlink for empty directories.Ludovic Courtès
Fixes <http://bugs.gnu.org/21280>. Reported by Leo Famulari <leo@famulari.name>. * tests/nar.scm (file-tree-equal?): Use #t as the initial result. Btrfs would set nlink to 1 instead of 2 for an empty directory, thereby leading 'file-tree-equal?' to return #f.
2015-06-24tests: Move 'file=?' to (guix tests).Ludovic Courtès
* tests/nar.scm (file-tree-equal?)[file=?]: Move to... * guix/tests.scm (file=?): ... here. New procedure.

2014-11-04tests: When a store item is to be deleted, make it statistically unique.Ludovic Courtès
Fixes <http://bugs.gnu.org/18935>. Reported by Mark H Weaver <mhw@netris.org>. Previously, if tests/nar.scm ran concurrently with tests/gexp.scm, the store item "foo" containing the string "Hello, world!" could be deleted (via 'delete-paths') from the tests/nar.scm daemon while the tests/gexp.scm daemon would still consider it live. * tests/nar.scm ("restore-file-set (missing signature)"): Use (random-text) rather than "Hello, world!", to avoid concurrent deletion of store item "foo" used in tests/gexp.scm.
2014-10-09Break module cycle involving (guix store) and (guix ui).Ludovic Courtès
Before, there was a cycle along the lines of: (guix store) -> (guix nar) -> (guix ui) -> (guix store) This caused problems, as discussed at: http://lists.gnu.org/archive/html/guix-devel/2014-10/msg00109.html This patch removes cycles in the (guix ...) modules. * guix/nar.scm (&nar-error, &nar-read-error, dump, write-contents, read-contents, %archive-version-1, write-file, restore-file): Move to... * guix/serialization.scm: ... here. * guix/store.scm: Remove dependency on (guix nar). * guix/scripts/hash.scm, guix/scripts/offload.scm, guix/scripts/substitute-binary.scm, tests/nar.scm, tests/store.scm, tests/substitute-binary.scm: Adjust accordingly.

(populate-file): Change 'make-random-bytevector' to 'random-bytevector'. Use (guix tests). * tests/store.scm (%seed, random-text): Remove. Use (guix tests).
2014-02-21nar: Produce archives with files sorted in C collation order.Ludovic Courtès
* guix/nar.scm (write-file) <directory>: Pass 'string<?' as the second argument to 'scandir'. * tests/nar.scm ("write-file puts file in C locale collation order"): New test.
2014-02-21nar: 'write-file' can write to non-file ports.Ludovic Courtès
