2022-05-29 | daemon: Clarify ‘--check’ error when outputs are missing....Drop the confusing ‘invalid’ jargon and display a hint like we do
for ‘--fallback’.
* nix/libstore/build.cc (DerivationGoal::outputsSubstituted): Rewrite error message.

2022-05-18 | daemon: runChild() is forbidden to talk during environment set up...DerivationGoal::startBuilder() is waiting for an empty line as a check that
the environment set up is fine.
Fixes <https://issues.guix.gnu.org/55324>.

2021-11-25 | daemon: Read substitute nar size as 'unsigned long long'....Fixes <https://issues.guix.gnu.org/46212>.
Reported by Christopher Baines <mail@cbaines.net>.
Previously, the nar size returned by 'guix substitute' would be read as
an 'int'; thus, values above 2^31 - 1 would be read and then stored as
negative integers in the database.
Regression introduced in 9dfa20a22ae0be3d3b01a7b3d422af97428c627e.
* nix/libstore/build.cc (SubstitutionGoal::finished): Use templatized
'string2Int' instead of 'std::atoi' to get an 'unsigned long long',
which is the type of 'hash.second'.
* tests/store.scm ("substitute and large size"): New test.
| Ludovic Courtès |
2021-11-25 | daemon: Read unsigned nar size and download size from substituter....Fixes <https://issues.guix.gnu.org/51983>.
Reported by Tobias Geerinckx-Rice <me@tobias.gr>.
* nix/libstore/local-store.cc (LocalStore::querySubstitutablePathInfos):
Expect 'unsigned long long' for 'downloadSize' and 'narSize'.
* tests/store.scm ("substitute query and large size"): New test.

2021-11-19 | daemon: Micro-optimize 'deletePath'....'remove' calls 'unlink' first and falls back to 'rmdir' upon EISDIR.
This change gets rid of the 'unlink' call for every directory being
removed.
* nix/libutil/util.cc (_deletePath): Call 'unlink' or 'rmdir' depending
on 'st.st_mode', rather than call 'remove'.
| Ludovic Courtès |
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.

2021-10-01 | build: Don’t delete ‘guix-gc.timer’ file....Without this invoking ‘make clean’ would remove ‘guix-gc.timer’, and ‘make’
would fail with.
make[2]: *** No rule to make target 'etc/guix-gc.timer', needed by 'all-am'. Stop.
* nix/local.mk (nodist_systemdservice_DATA): Remove ‘guix-gc.timer’.

2021-04-09 | daemon: 'guix substitute' replies on FD 4....This avoids the situation where error messages would unintentionally go
to stderr and be wrongfully interpreted as a reply by the daemon.
Fixes <https://bugs.gnu.org/46362>.
This is a followup to ee3226e9d54891c7e696912245e4904435be191c.

(process-substitution): Likewise.
(%error-to-file-descriptor-4?, with-redirected-error-port): Remove.
(%reply-file-descriptor): New variable.
(guix-substitute): Remove use of 'with-redirected-error-port'. Define
'reply-port' and pass it to 'process-query' and 'process-substitution'.

2021-03-18 | daemon: Prevent privilege escalation with '--keep-failed' [security]....Fixes <https://bugs.gnu.org/47229>.
Reported by Nathan Nye of WhiteBeam Security.
* nix/libstore/build.cc (DerivationGoal::startBuilder): When 'useChroot'
is true, add "/top" to 'tmpDir'.
(DerivationGoal::deleteTmpDir): Adjust accordingly. When
'settings.keepFailed' is true, chown in two steps: first the "/top"
sub-directory, and then rename "/top" to its parent.

2021-03-17 | daemon: Correctly handle '--discover' with no value....Previously, we'd get:
$ guix-daemon --discover
error: basic_string::_M_construct null not valid
* nix/nix-daemon/guix-daemon.cc (parse_opt): Change second argument to
'settings.set' to properly handle case where ARG is NULL.

2020-12-19 | daemon: Delegate deduplication to 'guix substitute'....This removes the main source of latency between subsequent downloads.
* nix/libstore/build.cc (SubstitutionGoal::tryToRun): Add a
"deduplicate" key to ENV.
(SubstitutionGoal::finished): Remove call to 'optimisePath'.
* guix/scripts/substitute.scm (process-substitution)[destination-in-store?]
[dump-file/deduplicate*]: New variables.
Pass #:dump-file to 'restore-file'.

Pass #:deduplicate? to 'process-substitution'.
* guix/serialization.scm (dump-file): Export and augment 'dump-file'.

2020-12-19 | daemon: Do not reset timestamps and permissions on substituted items....'guix substitute' now takes care of it via 'restore-file'.
* nix/libstore/build.cc (SubstitutionGoal::finished): Remove call to
'canonicalisePathMetaData'.
| Ludovic Courtès |
2020-12-19 | daemon: Let 'guix substitute' perform hash checks....This way, the hash of the store item can be computed as it is restored,
thereby avoiding an additional file tree traversal ('hashPath' call)
later on in the daemon. Consequently, it should reduce latency between
subsequent substitute downloads.
This is a followup to 5ff521452b9ec2aae9ed8e4bb7bdc250a581f203.
* guix/scripts/substitute.scm (narinfo-hash-algorithm+value): New
procedure.
(process-substitution): Wrap INPUT into a hash input port, 'hashed', and
read from it. Compare the actual and expected hashes, and print a
"hash-mismatch" status line when they differ. When they match, print
not just "success" but also the nar hash and size.
* nix/libstore/build.cc (class SubstitutionGoal)[expectedHashStr]:
Remove.
(SubstitutionGoal::finished): Tokenize 'status'. Parse it and handle
"success" and "hash-mismatch" accordingly. Call 'hashPath' only when
the returned hash is not SHA256.
(SubstitutionGoal::handleChildOutput): Remove 'expectedHashStr'
handling.
* tests/substitute.scm ("substitute, invalid hash"): Rename to...
("substitute, invalid narinfo hash"): ... this.
("substitute, invalid hash"): New test.
| Ludovic Courtès |
2020-12-08 | daemon: Raise an error if substituter doesn't send the expected hash....It was already impossible in practice for 'expectedHashStr' to be empty
if 'status' == "success".
* nix/libstore/build.cc (SubstitutionGoal::finished): Throw 'SubstError'
when 'expectedHashStr' is empty.
| Ludovic Courtès |
2020-12-08 | substitute: Cache and reuse connections while substituting....That way, when fetching a series of substitutes from the same server(s),
the connection is reused instead of being closed/opened for each
substitutes, which saves on network round trips and TLS handshakes.
* guix/http-client.scm (http-fetch): Add #:keep-alive? and honor it.
* guix/progress.scm (progress-report-port): Add #:close? parameter and
honor it.

'expectedHashStr' and 'status'.
(SubstitutionGoal::handleEOF): Call 'wakeUp' unconditionally.

to stdout upon success.
(%error-to-file-descriptor-4?): New variable.
(guix-substitute): Set 'current-error-port' to file descriptor 4
unless (%error-to-file-descriptor-4?) is false.
Remove "--substitute" arguments. Loop reading line from stdin.
