Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Hello,
An offloaded build that times out in the presence of ‘--keep-going’
leads to an assertion failure. To reproduce, set up offloading and run
something like this:
--8<---------------cut here---------------start------------->8---
$ guix build vim --no-substitutes --timeout=5 --keep-going
The following derivation will be built:
/gnu/store/5mnnym9xwl145s1b88aqfmrka810w9ci-vim-8.1.0644.drv
process 4277 acquired build slot '/var/guix/offload/localhost:2222/0'
load on machine 'localhost' is 0.04 (normalized: 0.01)
building /gnu/store/5mnnym9xwl145s1b88aqfmrka810w9ci-vim-8.1.0644.drv...
sending 1 store item (48 MiB) to 'localhost'...
exporting path `/gnu/store/mlwyk5vcja0gqm20xxj8mwgf0fbqv8cz-vim-8.1.0644-checkout'
building of `/gnu/store/5mnnym9xwl145s1b88aqfmrka810w9ci-vim-8.1.0644.drv' timed out after 5 seconds

guix build: error: corrupt input while restoring archive from #<closed: file 7ff2769cdc40>
--8<---------------cut here---------------end--------------->8---
The last error is due to premature EOF on the client socket: the child
‘guix-daemon’ process crashed, and thus ‘guix build’ gets EPIPE on its
client socket. Here’s how the ‘guix-daemon’ process crashed:
--8<---------------cut here---------------start------------->8---
$ tail -3 /var/log/guix-daemon.log
accepted connection from pid 4270, user ludo
accepted connection from pid 4277, user root
guix-daemon: nix/libstore/build.cc:3448: void nix::Worker::run(const Goals&): Assertion `!settings.keepGoing || children.empty()' failed.
--8<---------------cut here---------------end--------------->8---
In Cuirass, this manifests itself with EPIPE while writing to the client
socket:
--8<---------------cut here---------------start------------->8---

This bug is almost certainly a consequence of commit

Fixed by af73beeba1fc9effab60b11aea1d7ed8c24e7367.
I’ll update the ‘guix’ package soonish.
