daemon: Use unbranded phrases in comments and messages.

2018-12-16T15:28:07Z

* nix/libstore/build.cc, nix/libstore/globals.cc, nix/libstore/gc.cc, nix/libstore/local-store.cc, nix/libstore/optimise-store.cc, nix/libstore/store-api.cc, nix/libutil/archive.cc, nix/nix-daemon/nix-daemon.cc: Replace "Nix store" by "store", and "Nix daemon" by "build daemon".

daemon: Ignore '--keep-failed' for TCP/IP clients.

2018-11-24T18:52:16Z

* nix/nix-daemon/nix-daemon.cc (performOp) : When 'isRemoteConnection' is true, set 'settings.keepFailed' to zero. * doc/guix.texi (Common Build Options): Document this behavior.

daemon: Support multiplexed build output.

2018-10-15T20:40:35Z

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) : 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-daemon: Disable garbage collection for remote connections.

2018-04-19T17:06:26Z

* nix/nix-daemon/nix-daemon.cc (isRemoteConnection): New variable. (performOp): For wopCollectGarbage, throw an error when isRemoteConnection is set. (acceptConnection): Set isRemoteConnection when connection is not AF_UNIX. * tests/guix-daemon.sh: Add a test for the new behavior.

daemon: Flush the sink upon 'exportPath' errors.

2017-07-17T13:13:41Z

Prior to this change, errors such as wrong permissions on /etc/guix/signing-key.sec would give: guix-daemon: nix/libutil/serialise.cc:15: virtual nix::BufferedSink::~BufferedSink(): Assertion `!bufPos' failed. This patch correctly propagates the error to the client and thus changes that to: error: build failed: file `/etc/guix/signing-key.sec' should be secret (inaccessible to everybody else)! * nix/nix-daemon/nix-daemon.cc (performOp): Wrap 'exportPath' call in 'try' block.

daemon: Allow compilation with GCC 4.9.

2017-07-10T09:55:54Z

Reported by Ricardo Wurmus. * nix/nix-daemon/nix-daemon.cc (acceptConnection): Remove intermediate 'inaddr' variables that relied on implicit casts. This fixes compilation with GCC 4.9.

daemon: Set TCP_NODELAY and TCP_QUICKACK on remote sockets.

2017-06-22T08:59:07Z

* nix/nix-daemon/nix-daemon.cc (acceptConnection): Set TCP_NODELAY and TCP_QUICKACK on REMOTE.

daemon: '--listen' can be passed several times, can specify TCP endpoints.

2017-06-22T08:59:07Z

* nix/nix-daemon/guix-daemon.cc (DEFAULT_GUIX_PORT): New macro. (listen_options): New variable. (parse_opt): Push back '--listen' options to LISTEN_OPTIONS. (open_unix_domain_socket, open_inet_socket) (listening_sockets): New functions. (main): Use it. Pass SOCKETS to 'run'. * nix/nix-daemon/nix-daemon.cc (matchUser): Remove. (SD_LISTEN_FDS_START): Remove. (acceptConnection): New function. (daemonLoop): Rewrite to take a vector of file descriptors, to select(2) on them, and to call 'acceptConnection'. (run): Change to take a vector of file descriptors. * tests/guix-daemon.sh: Add test.

daemon: Client settings no longer override daemon settings.

2017-01-15T14:43:22Z

Fixes . * nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0x161. * nix/nix-daemon/nix-daemon.cc (performOp): "build-max-jobs", "build-max-silent-time", and "build-cores" are no longer read upfront; instead, read them from 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.

daemon: Set ownership of kept build directories to the calling user.

2016-12-09T14:46:09Z

Fixes . * 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.
