Summary: Useless font auto-installer calls
https://bugzilla.redhat.com/show_bug.cgi?id=531105
Summary: Useless font auto-installer calls
Product: Fedora
Version: rawhide
Platform: All
OS/Version: Linux
Status: NEW
Severity: medium
Priority: low
Component: fontconfig
AssignedTo: besfahbo(a)redhat.com
ReportedBy: nicolas.mailhot(a)laposte.net
QAContact: extras-qa(a)fedoraproject.org
CC: besfahbo(a)redhat.com, fedora-fonts-bugs-list(a)redhat.com
Classification: Fedora
The font stack triggers the PK font auto-installer for stuff like N'ko or
Ancient Persian for which fontconfig has no orthography
Therefore, those calls will never succeed and the user is bothered for no good
reason
fc-query/cache should also generate PK metadata for unicode blocks, so that
when the font stack needs a glyph which is not part of an orthography, PK can
search for fonts that cover the corresponding unicode block (stuff like symbols
will probably never make it in an orth)

This is surely a bug. And easy to fix, in at least two ways on the PK side:
1) Only show a dialog if there's any font supporting that language. This was
supposed to be the default. Not sure why it wasn't implemented this way.
2) In the GTK+ module, use FcLangGetCharset() to check whether fc knows about
the language.
IMO both of them should be done.
fc-query/cache should also generate PK metadata for unicode blocks,
so that
when the font stack needs a glyph which is not part of an orthography, PK can
search for fonts that cover the corresponding unicode block (stuff like symbols
will probably never make it in an orth)
Not a huge fan of this. Lets add orth's where missing.

PK asks for permission to search for fonts, and since it has not searched yet,
it does not know if there's any font supporting that language yet

language. This was

We're working with the yum guys to make this possible.
2) In the GTK+ module, use FcLangGetCharset() to check whether fc
knows about
the language.
At what point should the module call FcLangGetCharset? Somewhere like
http://cgit.freedesktop.org/packagekit/tree/contrib/gtk-module/pk-gtk-mod...
?

Not a huge fan of this. Lets add orth's where missing.
So if I submitted a fontconfig rfe to add an .orth for math symbols,
engineering symbols, dingbats, ancient persian, etc would it be accepted?
If yes what namespace should be used for those orths? I think ancient scripts
have standardised ids ISO-side, but symbols?

Oh, that's what you meant. I believe there's a bug upstream about it?
That's
a separate issue and we need to figure it out, yeah.

Please can you try the build of PackageKit here:
http://koji.fedoraproject.org/koji/taskinfo?taskID=1776157
You will need to reboot your computer to ensure the packagekitd process has
been restarted. Please provide feedback to whether this build fixes this bug.
Thanks.
Richard.
