Multi-version system-wide locales

[Ludovic Courtès]

Hello!

I just pushed the last bit to deal with the locale data incompatibility
issue on GuixSD; doc below.

Ludo’.


7.2.6.1 Locale Data Compatibility Considerations


‘operating-system’ declarations provide a ‘locale-libcs’ field to
specify the GNU libc packages that are used to compile locale
declarations (*note operating-system Reference::).  “Why would I care?”,
you may ask.  Well, it turns out that the binary format of locale data
is occasionally incompatible from one libc version to another.

   For instance, a program linked against libc version 2.21 is unable to
read locale data produced with libc 2.22; worse, that program _aborts_
instead of simply ignoring the incompatible locale data(1).  Similarly,
a program linked against libc 2.22 can read most, but not all, the
locale data from libc 2.21 (specifically, ‘LC_COLLATE’ data is
incompatible); thus calls to ‘setlocale’ may fail, but programs will not
abort.

   The “problem” in GuixSD is that users have a lot of freedom: They can
choose whether and when to upgrade software in their profiles, and might
be using a libc version different from the one the system administrator
used to build the system-wide locale data.

   Fortunately, unprivileged users can also install their own locale
data and define GUIX_LOCPATH accordingly (*note ‘GUIX_LOCPATH’ and
locale packages: locales-and-locpath.).

   Still, it is best if the system-wide locale data at
‘/run/current-system/locale’ is built for all the libc versions actually
in use on the system, so that all the programs can access it—this is
especially crucial on a multi-user system.  To do that, the
administrator can specify several libc packages in the ‘locale-libcs’
field of ‘operating-system’:

 (use-package-modules base)

 (operating-system
   ;; …
   (locale-libcs (list glibc-2.1 (canonical-package glibc

   This example would lead to a system containing locale definitions for
both libc 2.21 and the current version of libc in
‘/run/current-system/locale’.

   -- Footnotes --

   (1) Versions 2.23 and later of GNU libc will simply skip the
incompatible locale data, which is already an improvement.

Re: [PATCH] system: grub: On MIPS, the linux image name is vmlinuz

Another issue: I changed the GRUB upgrade to use a more recent commit,
which includes the two MIPS patches that are used in wip-loongson2f.

However, GRUB fails one test on x86_64:

The video test failure is a showstopper I think, and it would require
quite a bit of work to investigate.

Do you think you could help with these two things?  Otherwise we can
just postpone GuixSD/mips64el to the next release.

[PATCH] scripts: environment: Allow lists of packages in expressions.

[David Thompson]

Thanks to avoine on freenode for motivating me to finally add this
feature.  I've wanted it for awhile, but not badly enough to actually
implement it until now.  This is a cool feature because you can do stuff
like this now:

guix environment --ad-hoc -e '(@ (gnu) %base-packages)'

Pretty cool!

Yes, I know about this, but I'm not sure of a good solution.

The issue is that the default command to evaluate is $SHELL or
"/bin/sh."  You can be almost certain that $SHELL is not going to be
available in the container.  What to do?  Check if the command is
'equal?' to (list (getenv "SHELL")) and make it '("/bin/sh") instead?

I don't think so, because of the issue mentioned above.  I'm thinking
that the default shell should remain the Bash we mount at /bin/sh.

Open to, and looking for, ideas to improve things.  Let me know what
you think of all this.

I was not quite sure if this flag did not disable too much; but probably it
simply disables things that have been removed. So if its dependencies still
build, this should be the good fix for now.

> after this fix, I merge master into dbus-update.
> Do you think it's time to merge back?

Yes, I think so. On my list, only lablgtk remains. I added it at some point
in time because it is needed for the graphical version of unison (gtk+
bindings for ocaml). But building unison with gtk+ requires more, and in
the meantime I got used to the command line version of unison.

Maybe now we should first wait for the dbus-update branch to build after
the master merge (which hopefully will not take too long), and then
merge back?

> Sorry for all the trouble I made..

No problem! I think it would have been more efficient to advance by smaller
steps. But altogether, we have made a big step forward, and your enthusiasm
for updating complicated packages is much appreciated.

Cheers,

Andreas

I don't think you've made any trouble.  On the contrary, I very much
appreciate the updates!

For what it's worth, I see no problem with doing several updates on a
branch and taking a few weeks to fix the resulting problems.  This is
very similar to what often happens on 'core-updates'.  Given the
limitations of our build farm, I see no better way to accomplish this
task.  Doing a full rebuild after each update would take far too long.

Ping!

I think rb-fsevent may not be required after all.  I packaged
ruby-listen and ruby-rb-inotify; “listen” probably only uses rb-fsevent
when on a Mac.

Since we already fixed the yard problem I would really like to push the
three or four (with “rb-fsevent”) Ruby packages and move on.  These are
the remaining packages:

ruby-rb-fsevent
ruby-rubygems-tasks
ruby-ffi
ruby-simplecov-html

I have ruby-rb-inotify ready, but it depends on ruby-ffi; and
ruby-listen depends on ruby-rb-inotify.

OK.

OK to push.

I wonder if we should do that automatically by default.  That way
everyone would get the cool features, even those who didn’t bother to
read all the manual.

WDYT?

Thanks,

It’s not necessarily bz2, see ‘guix-daemon --disable-log-compression’.

The regexp should match 32 characters of ‘%nix-base32-chars’ in (guix
base32) if we want to be pedantic.

Good.

Could you update the patch accordingly?

Thanks,

Re: [PATCH] Add ruby-rb-inotify, ruby-listen, ruby-permutation.

[Thompson, David]

All of these LGTM.  If we encounter gems like inotify that use
Jeweler, then we should consider adding an argument to
ruby-build-system that allows one to toggle gemspec generation.

Hehe.  I need to do more research on this.  User/group mapping is
still pretty confusing to me.
