* offload: Fix error message in 'guix offload test'.Ludovic Courtès2018-06-15
| | | | | | | | Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com> in <https://bugs.gnu.org/31824>. * guix/scripts/offload.scm (assert-node-has-guix): Fix typo in failure message; add missing argument.
* offload: Gracefully handle invalid results from 'machines.scm'.Ludovic Courtès2018-06-14
| | | | | * guix/scripts/offload.scm (build-machines): Check the result of FILE. Ignore it if it's not a list of <build-machine>.
* offload: Honor the build timeout internally.Ludovic Courtès2018-06-11
| | | | | | * guix/scripts/offload.scm (call-with-timeout): New procedure. (with-timeout): New macro. (process-request): Use it around 'transfer-and-offload' call.
* offload: Look at machine loads for the past minute.Ludovic Courtès2018-01-15
| | | | | | | | | Previously we were looking at the load of the past 5 minutes, which means that, after a build, we could end up waiting for 5 minutes for that metric to be low enough. * guix/scripts/offload.scm (machine-load): Compute RAW based on ONE, not FIVE.
* offload: 'test' reports Guile and module errors more nicely.Ludovic Courtès2018-01-12
| | | | | | | | | | | Fixes <https://bugs.gnu.org/26008>. Reported by Myles English <mylesenglish@gmail.com>. * guix/ssh.scm (retrieve-files*): Move error reporting to... (report-guile-error, report-module-error): ... here. New procedures. * guix/scripts/offload.scm (assert-node-repl): Use 'report-guile-error'. (assert-node-has-guix): Explicitly check for 'use-modules' first. Use 'report-module-error'.
* offload: 'test' gracefully handles 'node-repl-error'.Ludovic Courtès2018-01-12
| | | | | | | | Fixes <https://bugs.gnu.org/28057>. Reported by Ricardo Wurmus <rekado@elephly.net>. * guix/scripts/offload.scm (assert-node-has-guix): Catch 'node-repl-error' and call 'leave'.
* offload: Fix regression in file retrieval.Ludovic Courtès2018-01-12
| | | | | | | | | | | | | | | | This fixes a regression in 'retrieve-files*' introduced in 896fec476f728183b331cbb6e2afb891207b4205, whereby (guix scripts offload) would not read the initial sexp now sent by the remote host via 'store-export-channel'. This would effectively prevent file retrieval entirely when offloading. * guix/ssh.scm (retrieve-files*): New procedure, like former 'retrieve-files' but with an extra #:import parameter. (retrieve-files): Rewrite in terms of 'retrieve-files*'. (file-retrieval-port): Make private. * guix/scripts/offload.scm (transfer-and-offload): Pass #:import to 'retrieve-files*'. (retrieve-files*): Remove.
* guix: offload: Add "status" sub-command.Ricardo Wurmus2017-12-16
| | | | | | * guix/scripts/offload.scm (check-machine-status): New procedure. (guix-offload): Call it when the argument is "status". * doc/guix.texi (Daemon Offload Setup): Document it.
* Do not set '%fresh-auto-compile'.Ludovic Courtès2017-12-01
| | | | | | | | * guix/scripts/offload.scm (build-machines): Comment out '(set! %fresh-auto-compile #t)' since with Guile 2.2.3 it could lead to an actual rebuild of everything that gets loaded from there on. See <https://bugs.gnu.org/29226>. * guix/ui.scm (load*): Likewise.
* offload: Reduce the number of calls to 'machine-load'.Ludovic Courtès2017-10-12
| | | | | | | | | | | | | | | Previously we would call 'machine-load' once per machine, which was very costly when there were many machines. Now we arrange to call it only once on average (when all the machines have the same 'speed' value). * guix/scripts/offload.scm (random-seed, shuffle): New procedures. (choose-build-machine)[machines+slots+loads]: Rename to... [machines+slots]: ... this. Remove load from the tuples therein. [undecorate]: Adjust accordingly. [machine-less-loaded-or-faster?]: Remove. [machine-faster?]: New procedure. Sort MACHINES+SLOTS according to 'machine-faster?'. Call 'machine-load?' as the last thing.
* offload: Fix potential file descriptor and memory leak.Ludovic Courtès2017-07-25
| | | | | | | | | | | The '%slots' list could grow indefinitely; in practice though, guix-daemon is likely to restart 'guix offload' often enough. * guix/scripts/offload.scm (%slots): Remove. (choose-build-machine): Don't 'set!' %SLOTS. Return the acquired slot as a second value. (process-request): Adjust accordingly. Release the returned slot after 'transfer-and-offload'.
* offload: Disconnect sessions created by 'machine-load'.Ludovic Courtès2017-07-25
| | | | | | | | This fixes a memory leak that can be seen by running: (map (lambda _ (machine-load m)) (iota 1000)) * guix/scripts/offload.scm (machine-load): Add call to 'disconnect!'.
* derivations: Introduce 'read-derivation-from-file'.Ludovic Courtès2017-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids the open/fstat/close syscalls upon a cache hit that we had with the previous idiom: (call-with-input-file file read-derivation) where caching happened in 'read-derivation' itself. * guix/derivations.scm (%read-derivation): Rename to... (read-derivation): ... this. (read-derivation-from-file): New procedure. (derivation-prerequisites, substitution-oracle) (derivation-prerequisites-to-build): (derivation-path->output-path, derivation-path->output-paths): (derivation-path->base16-hash, map-derivation): Use 'read-derivation-from-file' instead of (call-with-input-file … read-derivation). * guix/grafts.scm (item->deriver): Likewise. * guix/scripts/build.scm (log-url, options->things-to-build): Likewise. * guix/scripts/graph.scm (file->derivation): Remove. (derivation-dependencies, %derivation-node-type): Use 'read-derivation-from-file' instead. * guix/scripts/offload.scm (guix-offload): Likewise. * guix/scripts/perform-download.scm (guix-perform-download): Likewise. * guix/scripts/publish.scm (load-derivation): Remove. (narinfo-string): Use 'read-derivation-from-file'.
* scripts: Set thread names.Ludovic Courtès2017-05-28
| | | | | | | | | | | | | This allows 'guix publish' threads as well as 'guix substitute' and 'guix offload' processes to be properly labeled in 'top', 'pstree', etc. * guix/workers.scm (worker-thunk): Add #:thread-name parameter and honor it. (make-pool): Likewise. * guix/scripts/publish.scm (http-write): Add calls to 'set-thread-name' in bodies of 'call-with-new-thread'. (guix-publish): Call 'set-thread-name'. Pass #:thread-name to 'make-pool'. * guix/scripts/offload.scm (guix-offload): Call 'set-thread-name'. * guix/scripts/substitute.scm (guix-substitute): Likewise.
* ui: Rename '_' to 'G_'.Ludovic Courtès2017-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids collisions with '_' when the latter is used as a 'match' pattern for instance. See <https://lists.gnu.org/archive/html/guix-devel/2017-04/msg00464.html>. * guix/ui.scm: Rename '_' to 'G_'. * po/guix/Makevars (XGETTEXT_OPTIONS): Adjust accordingly. * build-aux/compile-all.scm (warnings): Remove 'format'. * gnu/packages.scm, gnu/services.scm, gnu/services/shepherd.scm, gnu/system.scm, gnu/system/shadow.scm, guix/gnupg.scm, guix/http-client.scm, guix/import/cpan.scm, guix/import/elpa.scm, guix/import/pypi.scm, guix/nar.scm, guix/scripts.scm, guix/scripts/archive.scm, guix/scripts/authenticate.scm, guix/scripts/build.scm, guix/scripts/challenge.scm, guix/scripts/container.scm, guix/scripts/container/exec.scm, guix/scripts/copy.scm, guix/scripts/download.scm, guix/scripts/edit.scm, guix/scripts/environment.scm, guix/scripts/gc.scm, guix/scripts/graph.scm, guix/scripts/hash.scm, guix/scripts/import.scm, guix/scripts/import/cpan.scm, guix/scripts/import/cran.scm, guix/scripts/import/crate.scm, guix/scripts/import/elpa.scm, guix/scripts/import/gem.scm, guix/scripts/import/gnu.scm, guix/scripts/import/hackage.scm, guix/scripts/import/nix.scm, guix/scripts/import/pypi.scm, guix/scripts/import/stackage.scm, guix/scripts/lint.scm, guix/scripts/offload.scm, guix/scripts/pack.scm, guix/scripts/package.scm, guix/scripts/perform-download.scm, guix/scripts/publish.scm, guix/scripts/pull.scm, guix/scripts/refresh.scm, guix/scripts/size.scm, guix/scripts/substitute.scm, guix/scripts/system.scm, guix/ssh.scm, guix/upstream.scm: Use 'G_' instead of '_'. Most of this change was obtained by running: "sed -i -e's/(_ "/(G_ "/g' `find -name \*.scm`".

* Break module cycle involving (guix store) and (guix ui).Ludovic Courtès2014-10-09
| | | | | | | | | | | | | | | | | | | | Before, there was a cycle along the lines of: (guix store) -> (guix nar) -> (guix ui) -> (guix store) This caused problems, as discussed at: http://lists.gnu.org/archive/html/guix-devel/2014-10/msg00109.html This patch removes cycles in the (guix ...) modules. * guix/nar.scm (&nar-error, &nar-read-error, dump, write-contents, read-contents, %archive-version-1, write-file, restore-file): Move to... * guix/serialization.scm: ... here. * guix/store.scm: Remove dependency on (guix nar). * guix/scripts/hash.scm, guix/scripts/offload.scm, guix/scripts/substitute-binary.scm, tests/nar.scm, tests/store.scm, tests/substitute-binary.scm: Adjust accordingly.
