<rekado>the failing process has these _NIX_OPTIONS:
<rekado> _NIX_OPTIONS=build-fallback=false\nbuild-use-substitutes=true\nmultiplexed-build-output=true\nsubstitute-urls=\nuntrusted-locale=en_US.UTF-8\nuntrusted-print-extended-build-trace=1\nuntrusted-terminal-columns=238
<rekado>I’ll pass this to the separate “guix substitute” process and see what happens
<civodul>yes; those \n are inconvenient
<civodul>i didn't want to distract you though :-)
<rekado>I ran “guix substitute” with the exact same environment as the failing process; it does not fail
<rekado>for the record, here’s the command:
<rekado>echo "substitute /gnu/store/l0jsrzgxdcghb87gly3zc5mvr9ylxi8g-0ad-data-0.0.23b-alpha /gnu/remote/0ad" | _NIX_OPTIONS="build-fallback=false\nbuild-use-substitutes=true\nmultiplexed-build-output=true\nsubstitute-urls=\nuntrusted-locale=en_US.UTF-8\nuntrusted-print-extended-build-trace=1\nuntrusted-terminal-columns=238" GUIX_LOCPATH=/gnu/remote/locales/.guix-profile/lib/locale
<rekado>SSL_CERT_FILE=/etc/pki/tls/certs/ca-bundle.crt PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin PWD=/ LANG=en_US.UTF-8 SHLVL=0 GUIX=/gnu/store/r8xb0r8vdvhyrjm61yih27gkxl2p8f6k-guix-command GUIX_STATE_DIRECTORY=/gnu/var/guix GUIX_CONFIGURATION_DIRECTORY=/etc/guix NIX_STORE_DIR=/gnu/store guix substitute --substitute
<rekado>oh, I see that this substitute command prints “Downloading”
<rekado>http instead of https
<civodul>looks like _NIX_OPTIONS is being ignored
<civodul>what if you just reduce it to: _NIX_OPTIONS=substitute-urls=
<PurpleSym>rekado_: Thanks for taking a look, I’ll fix that.
***rekado_ is now known as rekado
<rekado>I wrote the nix options to a file (with proper newlines), and set them all with _NIX_OPTIONS=`cat nix-options`
<rekado>I can see that they are in effect, because the output is now the usual daemon status strings (like “@ download-progress […]”)
<rekado>but… it still doesn’t fail
<rekado>I’ve set *all* of the environment variables and all of the _NIX_OPTIONS that are also in effect in the failing invocation.
<rekado>an obvious difference now is deduplication
<rekado>the standalone command does not have to deal with deduplication, so there are fewer syscalls
<rekado>I should try artificially slowing down the network to simulate the delays caused by performing more work on NFS.
