* guix/scripts/offload.scm (open-ssh-session): Add 'max-silent-time'
parameter. Add call to 'session-set!' before returning SESSION.
(transfer-and-offload): Pass MAX-SILENT-TIME to 'open-ssh-session'.
(%short-timeout): New variable.
(choose-build-machine): Pass %SHORT-TIMEOUT to 'open-ssh-session'.
(check-machine-availability): Likewise.
(check-machine-status): Likewise.
| Ludovic Courtès |
2019-09-28 | offload: Include the port number in the machine lock file name....This is useful when a single machine appears several time, with
different port numbers.
* guix/scripts/offload.scm (machine-slot-file): Add MACHINE's port to
the file name.
| Ludovic Courtès |
2019-06-05 | syscalls: Add 'with-file-lock' macro....* guix/scripts/offload.scm (lock-file, unlock-file, with-file-lock):
Move to...
* guix/build/syscalls.scm: ... here.
| Ludovic Courtès |
2019-01-22 | offload: 'status' reports the time difference....* guix/scripts/offload.scm (check-machine-status): Report the time
difference for each MACHINE.
| Ludovic Courtès |
2019-01-21 | store: Rename '&nix-error' to '&store-error'....* guix/store.scm (&nix-error): Rename to...
(&store-error): ... this, and adjust users.
(&nix-connection-error): Rename to...
(&store-connection-error): ... this, and adjust users.
(&nix-protocol-error): Rename to...
(&store-protocol-error): ... this, adjust users.
(&nix-error, &nix-connection-error, &nix-protocol-error): Define these
condition types and their getters as deprecrated aliases.

2018-12-26 | offload: Remove unnecessary locking on machine slots....This extra level of locking turned out to be unnecessary.
* guix/scripts/offload.scm (with-machine-lock): Remove.
(machine-lock-file): Remove.
(acquire-build-slot): Remove surrounding 'with-machine-lock'.
| Ludovic Courtès |
2018-12-26 | offload: Remove the "machine choice" lock....This lock was unnecessary and it led to a contention when many 'guix
offload' processes are polling for available machines.
* guix/scripts/offload.scm (machine-choice-lock-file): Remove.
(choose-build-machine): Remove surrounding 'with-file-lock (machine-lock-file)'.
| Ludovic Courtès |
2018-12-25 | offload: Adjust 'test' and 'status' to the latest changes....This is a followup to ed7b44370f71126087eb953f36aad8dc4c44109f;
following that commit, 'guix offload test' and 'guix offload status'
would abort with a backtrace instead of clearly diagnosing a missing
'guix' command on the build machine.
* guix/scripts/offload.scm (assert-node-has-guix): Call 'leave' when
NODE is not an inferior. Remove 'catch' blocks for 'node-repl-error'.
(check-machine-availability): Invoke 'assert-node-has-guix' first.
(check-machine-status): Print a warning when 'remote-inferior' returns #f.
| Ludovic Courtès |
2018-12-24 | offload: Use (guix inferior) instead of (ssh dist node)....Using inferiors and thus 'guix repl' simplifies setup on build
machines (no need to worry about GUILE_LOAD_PATH etc.)
Furthermore, the 'guix repl -t machine' protocol running in a remote
pipe addresses several issues with the current implementation of nodes
and RREPLs in Guile-SSH: fewer round trips, doesn't leave a 'guile
--listen' process behind it, stateless (since a new process is started
each time), more efficient (the SSH channel can be reused), more
reliable (no 'pgrep', 'pkill', and shellology; see
<https://github.com/artyom-poptsov/guile-ssh/issues/11> as an example.)
* guix/ssh.scm (inferior-remote-eval): New procedure.
(send-files): Use it instead of 'make-node' and 'node-eval'.
* guix/scripts/offload.scm (node-guile-version): New procedure.
(node-free-disk-space, transfer-and-offload, node-load)
(choose-build-machine, assert-node-has-guix): Use 'remote-inferior'
instead of 'make-node' and 'inferior-eval' instead of 'node-eval'.
(assert-node-can-import, assert-node-can-export): Likewise, and add
'session' parameter.
(check-machine-availability): Likewise, and add calls to
'close-inferior' and 'disconnect!'.
(check-machine-status): Likewise.
* doc/guix.texi (Daemon Offload Setup): Remove bit related to 'guile' in
$PATH and $GUILE_LOAD_PATH; mention 'guix' alone.
| Ludovic Courtès |
2018-12-23 | offload: Display the normalized load in 'guix offload status' output....Fixes a regression introduced in
bbe66a530a014e8146d63002a5294941e935f863 whereby the actual
load (non-normalized) would be displayed.
* guix/scripts/offload.scm (check-machine-status): Add call to
'normalized-load'.
| Ludovic Courtès |
2018-12-21 | offload: Recognize build failures due to lack of disk space....Previously, if a remote build would fail due to lack of disk space, this
would be considered a permanent failure and thus cached as a build
failure if the local daemon runs with '--cache-failures'.
* guix/scripts/offload.scm (transfer-and-offload): Upon
'nix-protocol-error?' call 'node-free-disk-space' and return 1 instead
of 100 if the result if lower than 10 MiB.
| Ludovic Courtès |
2018-12-21 | offload: Skip machines that are low on disk space....Fixes <https://bugs.gnu.org/33378>.
* guix/scripts/offload.scm (node-free-disk-space): New procedure.
(%minimum-disk-space): New variable.
(choose-build-machine): Call 'node-free-disk-space' and take it into
account in addition to LOAD.
(check-machine-status): Display the free disk space.
| Ludovic Courtès |
2018-12-21 | offload: Decompose 'machine-load' into simpler procedures....* guix/scripts/offload.scm (machine-load): Remove.
(node-load, normalized-load): New procedures.
(choose-build-machine): Call 'open-ssh-session' and 'make-node' from
here; pass the node to 'node-load'.
(check-machine-status): Use 'node-load' instead of 'machine-load'. Call
'disconnect!' on SESSION.
| Ludovic Courtès |
2018-06-15 | offload: Fix error message in 'guix offload test'....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.
| Ludovic Courtès |
2018-06-14 | offload: Gracefully handle invalid results from 'machines.scm'....* guix/scripts/offload.scm (build-machines): Check the result of FILE.
Ignore it if it's not a list of <build-machine>.
| Ludovic Courtès |
2018-06-11 | offload: Honor the build timeout internally....* guix/scripts/offload.scm (call-with-timeout): New procedure.
(with-timeout): New macro.
(process-request): Use it around 'transfer-and-offload' call.
| Ludovic Courtès |
2018-01-15 | offload: Look at machine loads for the past minute....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.
| Ludovic Courtès |
2018-01-12 | offload: 'test' reports Guile and module errors more nicely....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'.
| Ludovic Courtès |
2018-01-12 | offload: 'test' gracefully handles 'node-repl-error'....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'.
| Ludovic Courtès |
2018-01-12 | offload: Fix regression in file retrieval....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.
| Ludovic Courtès |
2017-12-16 | guix: offload: Add "status" sub-command....* 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.
| Ricardo Wurmus |
2017-12-01 | Do not set '%fresh-auto-compile'....* 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.
| Ludovic Courtès |
2017-10-12 | offload: Reduce the number of calls to 'machine-load'....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.
| Ludovic Courtès |
2017-07-25 | offload: Fix potential file descriptor and memory leak....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'.
| Ludovic Courtès |
2017-07-25 | offload: Disconnect sessions created by 'machine-load'....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!'.
| Ludovic Courtès |
2017-06-12 | derivations: Introduce 'read-derivation-from-file'....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/graph.scm (file->derivation): Remove.

(narinfo-string): Use 'read-derivation-from-file'.
| Ludovic Courtès |
2017-05-28 | scripts: Set thread names....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.
| Ludovic Courtès |
2017-05-03 | ui: Rename '_' to 'G_'....This avoids collisions with '_' when the latter is used as a 'match'
pattern for instance. See

21531add3205e400707c8fbfd841845f9a71863a whereby the build log would no
longer be sent to FD 4, thereby leading the daemon to not see the build
