On my i686 standalone Guix system, using Guix v0.7-642-g3b50925 to build
its 'guix' package (0.7.14e84b2) fails, due to a failed test. Here's
the relevant section from gexp.log:
--8<---------------cut here---------------start------------->8---
Test begin:
test-name: "gexp->derivation"
source-file: "tests/gexp.scm"
source-line: 227
source-form: (test-assert "gexp->derivation" (run-with-store %store (mlet*
%store-monad ((file (text-file "foo" "Hello, world!")) (exp -> (gexp (begin
(mkdir (ungexp output)) (chdir (ungexp output)) (symlink (string-append (ungexp
%bootstrap-guile) "/bin/guile") "foo") (symlink (ungexp file) (ungexp output
"2nd"))))) (drv (gexp->derivation "foo" exp)) (out -> (derivation->output-path
drv)) (out2 -> (derivation->output-path drv "2nd")) (done (built-derivations
(list drv))) (refs ((store-lift references) out)) (refs2 ((store-lift
references) out2)) (guile (package-file %bootstrap-guile "bin/guile"))) (return
(and (string=? (readlink (string-append out "/foo")) guile) (string=? (readlink
out2) file) (equal? refs (list (dirname (dirname guile)))) (equal? refs2 (list
file))))) #:guile-for-build (%guile-for-build)))
Test end:
result-kind: fail
actual-value: #f
actual-error: (srfi-34 #<condition &nix-protocol-error [message: "path

is not valid" status: 1] a587d68>)
--8<---------------cut here---------------end--------------->8---
The 'guix-daemon' used to do this failed build is also 0.7.14e84b2.
The 'guix' used to do this failed build was v0.7-642-g3b50925 plus one
local patch that adds
"--with-default-trust-store-file=/etc/ssl/certs/ca-certificates.crt" to
the GnuTLS configure flags.

This can only happen if FILE in that test were deleted after its
creation and before the ‘gexp-derivation’... which cannot even happen
since FILE remains live for the duration of the ‘%store’ session...
except if another daemon instance deletes it!
Commit 834ea02 fixes that: it turns out that tests/nar.scm was creating
the exact same store item, and then calling the GC to delete it.
I’ll update the Guix snapshot in Guix. (In the meantime, chances are
that you can just restart the build and won’t stumble upon this bug,
which was unlikely to occur.)
While looking at this code, I fixed a small issue with caches in
000c59b.
Thanks,
Ludo’.
