librsvg @2.36.4_3 fails to update /opt/local/etc/gtk-2.0/gdk-pixbuf.loaders

[earl_chew@…]

Although gdk-pixbuf-query-loaders --update-cache is used to update the cache, the text list of loaders in /opt/local/etc/gtk-2.0/gdk-pixbuf.loaders is not updated.

In the future, please fill in the Port field and Cc the port maintainers (port info --maintainers librsvg).

earl_chew: Is there a standard way to update the list of loaders?

[pixilla (Bradley Giesbrecht)]

The gdk-pixbuf2 port provides /opt/local/bin/gdk-pixbuf-query-loaders and gdk-pixbuf-query-loaders updates this cache file by default:

/opt/local/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache

The cache files /opt/local/etc/gtk-{2,3}.0/gdk-pixbuf.loaders are created by the gtk2 and gtk3 ports in post-activate.

I am unfamiliar with gtk but perhaps the gtk2 and gtk3 ports create their own loader cache files because they each add their own loaders natively so the common gdk-pixbuf2 cache won't work.

Would updating all three cache files improve the current situation?

The location of gdk-pixbuf and immodules cache files was moved from $sysconfigdir to $libdir (for GTK2 as well as GTK3):

• gdk-pixbuf: ​https://git.gnome.org/browse/gdk-pixbuf/commit/gdk-pixbuf/queryloaders.c?id=e3113c932232e76372f53f6b33b79ebe9be06720
• GTK2: ​https://git.gnome.org/browse/gtk+/commit/?h=gtk-2-24&id=c8849046860a9b17fa943247d85ddadb29262b48
• GTK3: ​https://git.gnome.org/browse/gtk+/commit/?id=0b0f176ac477e935fbabb31ba3c7030cded3b0d3

Likely the portfiles need to be updated accordingly to use the new paths and filenames.
(Edit: please verify current paths - some of the commits linked above are quite dated and AFAICT from before gdk-pixbuf was moved into a separate package).

Reassign librsvg-related tickets to me

AFAIK, this was fixed long ago.

If it's still an issue, please reopen.
