| 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.

| 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'.

| 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.

Call 'deduplicate' only when SIZE is greater than

* nix/libstore/gc.cc (LocalStore::removeUnusedLinks): Drop files where
st.st_size < deduplicationMinSize.

| 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

| 2020-01-12 | daemon: Account for deleted store files when deduplication is on....Previously, a store item that is a regular file would not be accounted
for in the 'bytesFreed' value computed by 'deletePath' because its
'st_nlink' count would always be >= 2. This commit fixes that.
* nix/libutil/util.hh (deletePath): Add optional 'linkThreshold' argument.
* nix/libutil/util.cc (_deletePath): Add 'linkThreshold' argument and
honor it. Pass it down in recursive call.
(deletePath): Add 'linkThreshold' and honor it.
* nix/libstore/gc.cc (LocalStore::deleteGarbage): Pass 'linkThreshold'
argument to 'deletePath', with a value of 2 when PATH is a store item
and deduplication is on.
