This ensures the stack is not unwound before the exception is re-thrown,
as was the case since 8ed597f4a2, leading
to '&store-protocol-error' being uncaught by 'with-error-handling'
in (guix scripts build) & co.
* guix/store.scm (call-with-store): Define 'thunk'. Add 'cond-expand'
to use 'with-exception-handler' on 'guile-3' and 'catch' otherwise.
Fixes <https://bugs.gnu.org/40428>.
Reported by Marius Bakke <mbakke@fastmail.com> and 白い熊.
Regression introduced with the first uses of 'with-build-handler' in
commit 62195b9a8f and subsequent.
* guix/store.scm (call-with-store): Use 'catch #t' instead of
'dynamic-wind'. This ensures STORE remains open when a non-local exit
other than an exception occurs, such as an abort to the build handler
prompt.
* tests/store.scm ("with-build-handler + with-store"): New test.
* guix/store.scm (<unresolved>): New record type.
(build-accumulator, map/accumulate-builds, mapm/accumulate-builds): New
procedures.
* tests/store.scm ("map/accumulate-builds", "mapm/accumulate-builds"):
New tests.
* guix/store.scm (current-build-prompt): New variable.
(call-with-build-handler, invoke-build-handler): New procedures.
(with-build-handler): New macro.
* tests/store.scm ("with-build-handler"): New test.
Partly fixes <https://bugs.gnu.org/39970>.
At least 'guix environment', 'guix install' and 'guix pull'
on 'az_AZ.utf8' and 'tr_TR.utf8' were affected.
* guix/store.scm (store-path-hash-part): Move base path detection to ...
(store-path-base): ... this new exported procedure.
(store-path-package-name): Use it instead of locale-dependent regexps.
(store-regexp*): Remove.
* guix/store.scm (current-target-system): New exported monadic procedure.
* guix/profiles.scm (profile-derivation): Set target at bind time using the
above procedure.
* guix/store.scm (current-target-system): New exported monadic procedure.
* guix/profiles.scm (profile-derivation): Set target at bind time using the
above procedure.
* guix/store.scm (cache-object-mapping): Add #:vhash-cons parameter and
honor it.
(lookup-cached-object): Add #:vhash-fold* parameter and honor it.
(%mcached): Add #:vhash-fold* and #:vhash-cons and honor them.
(mcached): Add clauses with 'eq?' and 'equal?' as the first argument.
Fixes <https://bugs.gnu.org/37744>.

Based on Nix commit 5a303093dcae1e5ce9212616ef18f2ca51020b0d
by Eelco Dolstra <edolstra@gmail.com>.
* nix/libstore/local-store.cc (LocalStore::LocalStore): Set 'perUserDir'
to #o755 instead of #o1777.
(LocalStore::createUser): New function.
* nix/libstore/local-store.hh (LocalStore): Add it.
* nix/libstore/store-api.hh (StoreAPI): Add it.
* nix/nix-daemon/nix-daemon.cc (performOp): In 'wopSetOptions', add
condition to handle "user-name" property and honor it.
(processConnection): Add 'userId' parameter. Call 'store->createUser'
when userId is not -1.
* guix/profiles.scm (ensure-profile-directory): Note that this is now
handled by the daemon.
* guix/store.scm (current-user-name): New procedure.
(set-build-options): Add #:user-name parameter and pass it to the daemon.
* tests/guix-daemon.sh: Test the creation of 'profiles/per-user' when
listening on a TCP socket.
* tests/store.scm ("profiles/per-user exists and is not writable")
("profiles/per-user/$USER exists"): New tests.
This is a followup to dd0ee954c4, which
introduced a failure in tests/graph.scm.
* guix/store.scm (run-with-store): Check whether STORE and NEW-STORE are
true before calling 'store-connection-object-cache' etc. Fixes a
failure in tests/graph.scm related to %REVERSE-PACKAGE-NODE-TYPE, which
uses #f as the store.
This increases the hit rate of the object cache from 56% to 85% when
running something like 'guix build libreoffice -nd'.
* guix/store.scm (set-store-connection-object-cache!): New procedure.
(run-with-store): Copy 'object-cache' field of the new store into the
original one.
This allows callers to request the substitution of a single derivation
output.
* guix/store.scm (build-things): Accept derivation/output pairs among
THINGS.
* guix/derivations.scm (build-derivations): Likewise.
* tests/store.scm ("substitute + build-things with specific output"):
New test.
* tests/derivations.scm ("build-derivations with specific output"):
New test.
* doc/guix.texi (The Store): Adjust accordingly.
The caching strategy introduced in
40cc850aeb was ineffective since we
regularly start from an empty object cache. For example, "guix build
inkscape -n" would make 241 'built-in-builders' RPCs.
* guix/store.scm (<store-connection>)[built-in-builders]: New field.
(open-connection): Adjust '%make-store-connection' call accordingly.
(port->connection): Likewise.
(built-in-builders): Rename to...
(%built-in-builders): ... this.
(built-in-builders): New procedure.
* guix/download.scm (built-in-builders*): Remove 'mcached' call.
This leads to ~25% improvements on things like:
guix system build desktop.tmpl --no-grafts -d
* guix/store.scm (<nix-server>)[object-cache]: New field.
* guix/store.scm (open-connection): Initialize it.
(cache-object-mapping, lookup-cached-object, %mcached): New procedures.
(mcached): New macro.
* guix/gexp.scm (lower-object): Use it.
* guix/grafts.scm (grafting?): New procedure.
This allows clients to tell whether output comes from the daemon or, if
it comes from a builder, from which builder it comes. The latter is
particularly useful when MAX-BUILD-JOBS > 1.
* nix/libstore/build.cc (DerivationGoal::tryBuildHook)
(DerivationGoal::startBuilder): Print the child's PID in "@ build-started"
traces.
(DerivationGoal::handleChildOutput): Define 'prefix', pass it to
'writeToStderr'.
* nix/libstore/globals.cc (Settings:Settings): Initialize
'multiplexedBuildOutput'.
(Settings::update): Likewise.
* nix/libstore/globals.hh (Settings)[multiplexedBuildOutput]: New field.
Update 'printBuildTrace' documentation.
* nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0.163.
* nix/nix-daemon/nix-daemon.cc (performOp) <wopSetOptions>: Special-case
"multiplexed-build-output" and remove "use-ssh-substituter".
* guix/store.scm (set-build-options): Add #:multiplexed-build-output?
and honor it.
(%protocol-version): Bump to #x163.
* tests/store.scm ("multiplexed-build-output"): New test.
fixlet
* guix/store.scm (derivation-log-file): New procedure.o
(log-file): Use it.
* guix/status.scm (print-build-event): Use 'derivation-log-file' instead
of 'log-file'. Check wheter the return value is #f.
This could result in deadlock in unusual situations, whereby we'd start
waiting for a reply while the query hasn't been flushed to the socket.
* guix/store.scm (buffering-output-port)[flush]: Add call to
'force-output'.
(add-to-store): Add call to 'write-buffered-output'.
* guix/store.scm (%not-slash): New variable.
(add-file-tree-to-store, interned-file-tree): New procedures.
* tests/store.scm ("add-file-tree-to-store"): New test.
Previously 'process-stderr' would always pass a bytevector of MAX-LEN to
then daemon in the %stderr-read case (i.e., 'import-paths'), instead of
LEN (where LEN <= MAX-LEN).
In practice the extra bytes didn't cause a protocol violation or
anything because they happen at the end of the stream, which typically
contains the canonical sexp of the signature, and the extra zeros were
just ignored.
* guix/serialization.scm (write-bytevector): Add optional 'l' parameter
and honor it.
* guix/store.scm (process-stderr): Pass LEN to 'write-bytevector'.
