Hi!
(Cc: Maxim who may be familiar with the ‘texlive-font-maps’ hook.)
I have Guile as a channel, which provides guile <at> 3.0.99-git. Trying to
add this guile package to a profile leads to a ‘texlive-font-maps.drv’
build failure:

So the failure is caused by the fact that /tmp/texlive is in fact empty.
How does this happen? I think there’s a logic failure in this bit of
‘texlive-font-maps’ in (guix profiles):
(mlet %store-monad ((texlive-base (manifest-lookup-package manifest "texlive-base")))
(if texlive-base
(gexp->derivation "texlive-font-maps" build
#:substitutable? #f
#:local-build? #t
#:properties
`((type . profile-hook)
(hook . texlive-font-maps)))
(return #f)))
In this case, ‘texlive-base’ is found among the native inputs of
guile <at> 3.0.99-git.
However, the profile itself contains zero texlive-* packages, hence the
failure.
There are probably two things to fix:
1. The ‘manifest-lookup-package’ check seems inconsistent with what’s
passed to ‘union-build’.
2. Perhaps the builder shouldn’t fail anyway when given an empty
/tmp/texlive.
Thoughts?

Did you checked with Ricardo? They were the author of that hook, per

I think this is the problem to fix. It's non-intuitive that
manifest-lookup-package transitively looks for things instead of looking
at the profile. I actually got tripped by that as well when I authored
gdk-pixbuf-loaders-cache-file, so there's now a comment in that same
file that reads:
;; XXX: MANIFEST-LOOKUP-PACKAGE transitively searches through
;; every input referenced by the manifest, while MANIFEST-INPUTS
;; only retrieves the immediate inputs as well as their
;; propagated inputs; to avoid causing an empty output derivation
;; we must ensure that the inputs contain at least one
;; loaders.cache file. This is why we include gdk-pixbuf or
;; librsvg when they are transitively found.
I think we need a 'manifest-lookup-inputs' or similar that stops at the
profile, to work at the same depth as manifest-inputs. Then it wouldn't
find texlive-base and the hook wouldn't run (and fail).
What do you think?

There were cases (like GDK pixbuf, GLib schemas, and all that) where the idea was to take whichever glib/GDK we’d find in the dependency graph, and pick the command we need from it. That way, we wouldn’t introduce any additional dependency. That was the reasoning. Thinking about, this particular case might be easier: we can make things consistent like so:

That way, the hook only fire if we have ‘texlive-base’ (somewhere in the graph) *and* we have texlive-* packages in the manifest. Thoughts? Ludo’.

That is equivalent, but it doesn't address the core problem in my opinion. There's no use to run hooks for things which aren't propagated at the level of the profile, I think. If texlive-base in is the profile, the person wants to use tex and friends. But if it's wrapped by some package deep down, we shouldn't care. I see it the same way as when using libraries and compilers in a profile; the compiler (consumer) needs to be present else no search path is created. Does it make sense? -- Thanks, Maxim

I agree with the reasoning; I think it doesn’t apply to the GLib schemas and GDK pixbuf caches though. For TeX Live font maps, maybe it applies, though I’m not entirely sure (I wouldn’t be surprised if things other than ‘texlive-base’ are consumers of font maps). Plus, since the patch I proposed is simple, I’m inclined to just do that. Thoughts? Ludo’.

It does, for the simple reasons that both GDK pixbufs and GLib schemas are collected using manifest-inputs, which means only direct inputs from the profile and the ones they propagate. So if you look deep in the profile graph for the 'glib-compile-schemas' command, there is a chance that it is found while no schemas were collected, and this is the kind of case that'd lead to an empty derivation output (because there's no schema to compile). > For TeX Live font maps, maybe it applies, though I’m not entirely sure > (I wouldn’t be surprised if things other than ‘texlive-base’ are > consumers of font maps).

I still think that my proposition is better, but I don't mind if you apply your fix now and we revisit this at a later time. If we get to it, this change could be reverted as it wouldn't be necessary anymore. -- Thanks, Maxim

Ah yes, that’s right. I was looking at it the other way around: GLib and GDK caches need to be built even if glib/gdk-pixbuf does not appear in the manifest. >> For TeX Live font maps, maybe it applies, though I’m not entirely sure >> (I wouldn’t be surprised if things other than ‘texlive-base’ are >> consumers of font maps).
