om the key/value list at the end. * nix/nix-daemon/guix-daemon.cc (main): Explicitly set 'settings.maxBuildJobs'. * guix/store.scm (%protocol-version): Bump to #x161. (set-build-options): #:max-build-jobs, #:max-silent-time, and #:build-cores now default to #f. Adjust handshake to new protocol. * tests/store.scm ("build-cores"): New test. * tests/guix-daemon.sh: Add test for default "build-cores" value. Ludovic Courtès 2016-12-09daemon: Set ownership of kept build directories to the calling user....Fixes <http://bugs.gnu.org/15890>. * nix/libstore/globals.hh (Settings) Add clientUid and clientGid. * nix/nix-daemon/nix-daemon.cc (daemonLoop] Store UID and GID of the caller in settings. * nix/libstore/build.cc (_chown): New function. (DerivationGoal::deleteTmpDir): Use it, change ownership of build directory if it is kept and the new owner is not root. Hartmut Goebel 2016-12-01daemon: Buffer data sent to clients by the 'export-path' RPC....Before that we'd have STDERR_WRITE round trips for very small amounts of data, ranging from a few bytes for the metadata of nars to the size of one file being exported. With this change, something like: guix archive --export /gnu/store/5rrsbaghh5ix1vjcicsl60gsxilhjnf2-coreutils-8.25 | dd of=/dev/null reports a throughput of 35 MB/s instead of 25 MB/s before. * nix/nix-daemon/nix-daemon.cc (TunnelSink): Inherit from 'BufferedSink' rather than 'Sink'. Rename 'operator ()' to 'write'. (performOp) <wopExportPath>: Add 'sink.flush' call. Ludovic Courtès 2016-11-16daemon: Add 'built-in-builders' RPC....* nix/libstore/builtins.cc (builtinBuilderNames): New function. * nix/libstore/builtins.hh (builtinBuilderNames): New declaration. * nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0x160. (WorkerOp)[wopBuiltinBuilders]: New value. * nix/nix-daemon/nix-daemon.cc (performOp): Handle it. * guix/store.scm (operation-id)[built-in-builders]: New value. * guix/store.scm (read-arg): Add 'string-list'. (built-in-builders): New procedure. * tests/derivations.scm ("built-in-builders"): New test. Ludovic Courtès 2016-03-16build: Default to "https://mirror.hydra.gnu.org/" for substitutes....* config-daemon.ac: Check for (gnutls) and define 'GUIX_SUBSTITUTE_URLS'. * nix/nix-daemon/guix-daemon.cc (main): Use GUIX_SUBSTITUTE_URLS. * guix/store.scm (%default-substitute-urls): Use 'https' when (gnutls) is available. * doc/guix.texi (Binary Installation): Mention mirrors (Invoking guix-daemon): Mention mirror.hydra.gnu.org. (Substitutes): Mention mirrors. (Invoking guix archive): Show https URLs. Ludovic Courtès
