In bug #517789 Behdad requests that rpm changed the command it uses to collect font metadata from fc-query to fc-scan
point 7 of https://bugzilla.redhat.com/show_bug.cgi?id=517789#c11

Given your worry about fontconfig files not being in buildroot in that comment, to which I don't see a response from Behdad so far... are you guys really sure this change should go in?

[Nicolas (nicolas-redhat-bugs)]

I'm only relaying Behdad's instructions there, so if you needinfo, needinfo him :)

From what I understand of fontconfig changing fc-query to fc-scan now is low impact and will at least take make rpm take into account the fontconfig rules shipped within the fontconfig package itself. Then once Behdad adds some way to point fc-scan to fontconfig files outside fontconfig default paths, it we can improve the system more by adding an argument to the fontconfig files in the buildroot to the fc-scan call

Of course, Behdad may have better ideas than me here

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

[Behdad (behdad-redhat-bugs)]

Oki doki, the machinery is already there.

RPM should use fc-query, and set envvar FONTCONFIG_FILE to the absolute path of a file containing the following:

<fontconfig>
<cachedir>path/to/build/dir/var/cache/fontconfig</cachedir>
<dir>path/to/build/dir/etc/fonts/conf.d</dir>
</fontconfig>

The cachedir is unused, but needs to be available. Alternatively you can point it to /tmp.

Let me know if it works.

[Nicolas (nicolas-redhat-bugs)]

Panu, is this something you can work with ? It does not seem the kind of stuff a package can request itself

[Nicolas (nicolas-redhat-bugs)]

Panu, I think that in F14 it's possible to move font autodep detection from rpm to other patckages. Would you be ok with moving this stuff in fontpackages-devel? (every font package in the distro depends on it) Can you give me some hints on how to do it?

macro config change.
rpm5 needs font config?

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

[Bug (bug-redhat-bugs)]

Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Uhm, somehow all these years passed...

Since rpm 4.9.x the font provides generation is controlled by two files:
/usr/lib/rpm/fileattrs/font.attr and /usr/lib/rpm/fontconfig.prov

To move the control to font SIG where it IMO belongs, just grab a copy of those into fontpackages-devel in same fs location and once its ready to build, drop me a note to axe them from rpm-build. And that's it. Well, perhaps explicit conflicts for a while wouldn't hurt, but that'd be "minor details".

Switching component to fontpackages as that's where the willingness to commit to the change and first step(s) need to come from.
