Hello,
Yesterday I was playing around with g-golf and libguile and encountered
some weird glib issues once I linked my c program to glib/gobject.
After asking about this in #guile the problem was discovered to be 2
different glibs being in use and the workaround is use them with
'--no-grafts' instead.
I looked into why grafting is causing this problem and here is what I
have found:
The following happend on guix commit
e16cdcf37d8223b3634ec5e658356c3b7f154859
Before grafting:
/gnu/store/digl75knygzqg9lrh8adk3pz0qg9cx8h-guile-g-golf-0.8.0-a.1:
Has a reference to: /gnu/store/zgsphhmliwgmjjv1czmbyjql3gk7ynsx-glib-2.78.0
which is the out output of the hidden (@@ (gnu packages glib) glib) package
After applying grafts:
/gnu/store/2ar2h8d7nk3g7c9965y4n68gjr778prk-guile-g-golf-0.8.0-a.1:
Has reference to /gnu/store/0466q5rlccclzg70f3yprpf9kdvlyfzf-glib-2.78.0
But the hidden glib grafts to
/gnu/store/ls9p0k2chrzviadibzf0iz7rlpkmggms-glib-2.78.0
instead (which is the one I am linking to)
Looking at the grafting derivations the issue seems to be that in one
case all outputs of glib are grafted and in the other case only the out
output which leads to the different results.

I think it would be good if grafts are only applied per output (which
might also help resolve #69653).

Hello Dariqq, your debugging is interesting.
My G-Golf GTK program has a critical error at Gdk-Pixbuf, not GLib at
first sight, but see below.
$ guile /gnu/store/hbf4wqssp0aa0m2cxrwaq0mkxfd5y59p-launcher.scm

Both my GLibs have one output only. I still believe above guix commit
is the first bad commit for you, as well, and
guix time-machine -q --commit=78c4d00ab02ab41a22058cdbec0329752e47580f
will show the error and parent commit
guix time-machine -q --commit=08e0144d2338c8fb51e52e74274554583d0faa69
will be fine. Is it?
I believe what we describe here is yet another symptom of old bug
<https://issues.guix.gnu.org/48907>, but if we have a first bad commit,
and if it is the first bad commit for you, too,
it might help solve it. Or perhaps this bug can be solved separately if
really the loading through typelib vs. not through typelib is the cause.
Regards,
Florian

Hello FLorian,
I think you are experiencing a different (related) issue because the
problem I seems to vanish by linking to the glib that is used by g-golf
instead (the --no-grafts options ensures that only one glib is in my
guix shell)

The problem i am seeing is still available in
08e0144d2338c8fb51e52e74274554583d0faa69.
Here is what I've been playing around with:
a simple c file that just loads a scm file.
a simple scm file that just tries to instantiate a gobject class (in
this example from json-glib but that is irrelevant, using something
small and simple)
--8<---------------cut here---------------start------------->8---
main.c:
#include <libguile.h>
int
main (int argc, char **argv)
{
scm_init_guile();
scm_c_primitive_load("foo.scm");
}
foo.scm:
(use-modules (g-golf))
(gi-import "Json")
(describe (make <json-parser>
#:immutable #t))
Build with
gcc -o main main.c \
`pkg-config --cflags --libs guile-3.0` \
`pkg-config --cflags --libs gobject-2.0`
Running this with grafts:
./main
(process:3071): GLib-GObject-CRITICAL **: 08:50:36.946:
g_object_new_is_valid_property: object class 'JsonParser' has no
property named 'immutable'
#<<json-parser> 7f186b2f56d0> is an instance of class <json-parser>
Slots are:
g-inst = #<pointer 0x1445e900>
(process:3071): GLib-GObject-CRITICAL **: 08:50:36.947:

g_object_get_is_valid_property: object class 'JsonParser' has no
property named 'immutable'
immutable = #f
When not linking to gobject , using no-grafts or running directly from
guile repl things work as I would expect:
./main
#<<json-parser> 7ff2471f1d20> is an instance of class <json-parser>
Slots are:
g-inst = #<pointer 0x2bbbe920>
immutable = #t
--8<---------------cut here---------------end--------------->8---
On 08e0144d2338c8fb51e52e74274554583d0faa69 a similar problem exists:
g-golf depends on the ungrafted out output of hidden glib
but full glib is getting grafted (because of other other outputs)
If I prepend the glib with the single output graft to pkgconfig path and
rebuild (s.t. my c prgram is linked to the same glib that is used by
g-golf) things start magically working again.

There might be an even bigger issue here?
However regardless of it causing issues I think having 2 different
grafted glibs (or rather anything) is not really great.

Hi Dariqq. Your glib and json bug is indeed different.
Your initial suggestion for a proper fix to the different but similar
troubles we both have:
> I think it would be good if grafts are only applied per output (which
> might also help resolve #69653).
is the same proposal as in bug#48907.

Therefore I will merge the two bugs.
Not entirely sure if this proper fix would currently need changes to the
C++ guix-daemon code. Anyway, I will not implement it.
Currently we both have workarounds, obviously disabling security updates
with --no-grafts is possible, but also you wrote you can set the
pkgconfig path. For GTK programs, a workaround is instead of putting
(list gdk-pixbuf
graphene gtk harfbuzz
pango)
in your Guix shell manifest or a scheme-file, I could instead rebuild
without grafts, like in Guix’ ungraft manifest.
That is, my previous home configuration for commit
