Subject: guix system reconfigure fails if config.scm contains LUKS
 mapped-devices
Date: Thu, 28 Dec 2017 23:18:04 +0100

Hello Guix,

When running `guix system reconfigure /etc/config.scm' as root I get the
following error:

guix system: error: failed to load '/etc/config.scm':
/etc/config.scm:24:9: /etc/config.scm:24:9: In procedure allocate-struct: Wrong type argument in position 2: 3

This error appears for the first time in commit
4ca90ff5976434a2b6e758df38df54387ae70c1b.  On line 24 of my config file
I have declared a mapped device of type luks-device-mapping.  If the
config file does not contain any mapped-devices declaration `guix system
reconfigure' works as expected (checked in a VM).

I run GuixSD on a x86_64 machine.

Greetings

Diego N. Barbato

Can you send your config.scm? 

Without it, it's hard to know if there is a problem with your config.scm or the Guix mapper-devices code.

When running `guix system reconfigure /etc/config.scm' as root I get the

As requested here is my config.scm.  Although I doubt there is a problem
with it since it works with commit
de2032b912ede1756290e7ca9f7af7e9b72627eb and the mapped-devices
declaration is the same as in the manual (except for the target and the
uuid).

I’m afraid you’ll have to “rm -rf ~/.cache/guile/ccache” (Guile’s
auto-compilation cache) to work around
e2721a05e7d778bdf845b7cb7a42fd9f76095b69.

Can you confirm?

This commit adapts to a change in what ‘%fresh-auto-compile’ does in
Guile 2.2.3, which turned out to be wrong.

Thanks,
Ludo’.

FYI, I also encountered the same issue recently, and indeed I needed to
clear the auto-compilation cache for my system configuration file, for
both my normal user and root.

It makes me wonder if "guix system" should force a fresh compilation of
that file by default.

It should, as it used to do, but in 2.2.3 I pushed a “fix” for
‘%fresh-auto-compile’ that turned out to be misguided: it would now
force a fresh-auto-compile of everything, including files for which we
have a .go not in ~/.cache but in some other $GUILE_LOAD_COMPILED_PATH
entry.

See
<https://git.savannah.gnu.org/cgit/guile.git/commit/?h=stable-2.2&id=83d4c4d622b406ec0bc9d8139ec8182fa72b5720>.

I think we should revert it and publish 2.2.4 soon.

Thoughts?

Yes, running `rm -rf ~/.cache/guile/ccache' fixes the issue.

I just ran into this, and clearing ~/.cache/guile/ccache did indeed fix
it.  Thanks.

FYI, more recently there has been another change that caused "guix
system build" to fail for me, and once again it was fixed by clearing
the auto-compilation cache for my system configuration.

Here's the error I got:

I guess that maybe the 'guix-configuration' record was changed, but I
haven't taken the time to find the commit that broke my cached
etc/config-sddm.go.

For now, in commit 92423868bc451600f8f3d93b638091d12b14b7aa, I’ve
arranged so that auto-compilation is turned off for Guile 2.2.3 only.

At the same time, I reverted the offending change in Guile, and
hopefully we’ll release 2.2.4 shortly:

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=29226#25

I’m not sure we can do much better for 2.2.3, or perhaps we should
always use (compile-file file #:to 'value) in ‘load*’?

Thanks,
Ludo’.

In commit f44c7aaccd1942b8bf7916e4c8bb0f8f1abfcb58 I added an explicit
‘compile-file’ call to update the cached .go file for the user’s config,
when on 2.2.3.

This should solve the problem most of the time.  The only remaining
issue is if you’re using 2.2.3 and your config spans several modules:
only the main .scm file is rebuilt, so there could be ABI issues in the
other modules.

I’m closing the bug now.

Ludo’.
