bug#34799: font breakage, square boxes

A recent update breaks my fonts for most programs, making all characters
show as empty boxes. This happens inside and outside tmux, across various
terminal emulators, etc. It does not occur in deluge-gtk or my TTY. I
experimented with rolling back and doing a partial upgrade from there. With
this list of packages to upgrade, the issue comes back.

The following packages will be upgraded:

It is hard to say what is to blame here. Three separate font packages are
being upgraded as well as fontconfig. Attached is a screenshot showing what
this breakage looks like. I worry that holding back fontconfig might  lead
to issues with the other fonts upgrading. I don't know if those fonts all
updated due to universal font changes.

bug#34799: font breakage, square boxes, font-terminus

[Bradley Haggerty]

This issue may be a lot simpler than it initially seemed. I've had success
upgrading all those packages except for font-terminus. I also realized that
the broken font in all places I can think of was the same. It was Terminus.
So, this bug is likely specific to font-terminus and for now I will just
hold it back in my upgrades.

I updated font-terminus from 4.40 to 4.47 in commit 73c5c482.  I 
wonder if your problem could be caused by this intermediate 
upstream change[0]:

  Version 4.46:
    The X11 8-bit code pages are not installed by default.

Indeed, I'd noticed that some half of the 4.40 files were 
‘missing’ from 4.47, but my fonts continued to work just fine and 
we don't (usually…) diverge from upstream without good reason.

This is probably a good reason :-)  Does the attached patch fix 
your problem?

Kind regards,

Sorry for the late reply. I've got a couple other guix issues I'm
struggling to sort out recently as well.

I'm a bit of a novice. Can you (or someone else) explain how I apply this
patch file?

No problem.  I hope you get them resolved.  I can only say that 
Guix is worth it.

You'd clone the Guix git repository from Savannah, ‘git am’ the 
patch e-mail in question, then follow the instructions in section 
14.2 (Running Guix Before It Is Installed) of the manual using 
‘./pre-inst-env guix package -i font-terminus’ to install the 
patched package.

However, you won't need to do any of that today.  :-)

I was already on the fence about just pushing this change anyway, 
and remembering the existence of outputs sealed the deal.  I 
always forget that they exist.  Installing ‘font-terminus’ still 
gives you the upstream selection, but could you

  $ guix pull
  $ guix package -i font-terminus:pcf-8bit
  $ fc-cache -fr

verify that the above command worked:

  $ fc-list | grep ter-116b
  …are/fonts/terminus/ter-116b.pcf.gz: Terminus:style=Bold

and see if your font situation improves?

If Terminus is actually unusable without those files, I'll add 
them back to :out.

Kind regards,

T G-R

It all looks good now! Thanks for the fix.

Here is the output showing that the font is installed properly:
brad@kazuki:~/ > fc-list | grep ter-116b
/home/brad/.guix-profile/share/fonts/terminus/ter-116b.pcf.gz:
Terminus:style=Bold

So now will I be all set or will there be another packaging change to look
out for now?
