| 2021-11-16 | daemon: 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.

| 2021-06-18 | Start 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.

negated, %test-match-all): New variables.
(main): Compute the test specifier based on the values of the new options and
apply it to the current test runner when running the test file.
* doc/guix.texi (Running the Test Suite): Document the new options.

| 2021-01-31 | build: test-driver.scm: Enable colored test results by default....The Automake parallel test harness does its own smart detection of the
terminal color capability and always provides the --color-tests argument to
the driver. This change defaults the --color-tests argument to true when the
test driver is run on its own (not via Automake).
* build-aux/test-driver.scm (main): Set the default value of the --color-tests
argument to true when it's not explicitly provided.

| 2021-01-31 | build: test-driver.scm: Make output redirection optional....This makes it easier (and less surprising) for users to experiment with the
custom Scheme test driver directly. The behavior is unchanged from Automake's
point of view.
* build-aux/test-driver.scm (main): Make the --log-file and --trs-file
arguments optional and update doc. Only open, redirect and close a port to a log file when
the --log-file option is provided. Only open and close a port to a trs file
when the --trs-file option is provided.
(test-runner-gnu): Set OUT-PORT parameter default value to the current output
port. Set the TRS-PORT parameter default value to a void port. Update doc.
