[PATCH 0/3] offload to Childhurd fails: setting synchronous mode: locking protocol |
|
Date: |
Wed, 1 Jul 2020 16:29:29 +0200 |
Hello Guix!
I configured my system with a childhurd service and added
--8<---------------cut here---------------start------------->8---
(build-machine
(name "childhurd")
(system "i586-gnu")
(host-key "ssh-ed25519 ... root@childhurd")
(user "root")
(private-key "/home/janneke/.ssh/id_rsa_childhurd"))
--8<---------------cut here---------------end--------------->8---
to /etc/guix/machines. Sadly, running guix offload test gives
--8<---------------cut here---------------start------------->8---
$ guix offload test
guix offload: testing 1 build machines defined in '/etc/guix/machines.scm'...
guix offload: Guix is usable on 'childhurd' (test returned
"/gnu/store/883yjkl46dxw9mzykykmbs0yzwyxm17z-test")
guix offload: 'childhurd' is running GNU Guile 3.0.4
guix offload: error: exception occurred on remote host 'localhost': (%exception
#<inferior-object #<&store-protocol-error message: "setting synchronous mode:
locking protocol" status: 1>>)
--8<---------------cut here---------------end--------------->8---
So, I looked into the Debian/Hurd sqlite3 package for inspiration and found
debian/patches/20-hurd-locking-style.patch...well, that should fix it, right?
Sadly, this patch seems to break sqlite3 altogether.

Maybe we're missing some file_lock patch that Debian has? Where to look,
glibc, hurd, ...? Ideas?
Greetings,

Sure, done!
