Description Gerold Schellstede 2013-09-28 17:10:45 UTC
Everytime I open a .pdf (e.g. /X/.../Y/Z.pdf) with acroread, fontconfig creates the directory /X/.../Y/fontconfig. Thereby X and Y are arbitrary directories.

This is only with fontconfig 2.10.92 and 2.10.93. If I mask these versions and merge 2.8.0-r1, everything works well. Therefore I act on the assumtion that fontconfig is the root of the problem.

It is reproducable on all maschines I tried.

media-libs/fontconfig-2.10.92 was built with the following:
Comment 3 Gerold Schellstede 2013-10-01 12:53:06 UTC
I figured out that the problem goes away if one copy one of the arbitrary created "fontconfig"-folders to ~/.fontconfig. 

If yout then delete ~/.fontconfig the problem comes back. 

It seems to me that fontconfig looks, if the folder ~/.fontconfig exists and if a expected file-subset is in there. If this is the case, fontconfig do nothing. If that is not the case, fontconfig creates this folder with content. At this point fontconfig 2.10.92 and 2.10.93 creates - in a different way from the previous version - the fontconfig folder in the directory where one open the .pdf file. The previous versions created ~/.fontconfig instead.

If you have a ~/.fontconfig folder created from an older fontconfig version one do not notice the bug. So I think that most of the users don't notice the problem, but it's there. 

Best regards

As someone pointed out in bug #486940, it appears that this issue is fixed in git master with the following commit.

I haven't been able to test it as there are too many changes since 2.10.93 to create a simple patch.
Comment 5 Gerold Schellstede 2013-10-06 12:18:55 UTC
Hello again,

thanks for your answer. I don't think that a patch is needed as one can workaround this problem. I postet the bug only to overcome the problem in further versions of fontconfig >2.10.93. 

I saw another bug reported in Bugzilla, that suffers from the same problem:

Here frontconfig creates a ~/fontconfig instead of ~/.fontconfig with skype. This is the same behaviour as you open a pdf from "Desktop".

So I think the problem is definetly fontconfig and not acroread (or skype).  

Best regards

Please test fontconfig-2.11.0 and tell us whether this issue has been solved.
Comment 7 Gerold Schellstede 2013-10-24 10:43:30 UTC
No, the problem is still the same with this version (2.11.0).

I think acroread uses fontconfig from app-emulation/emul-linux-x86-xlibs
Comment 9 Ben de Groot (RETIRED) gentoo-dev 2013-10-26 10:38:16 UTC
@multilib: it looks like you need to update the fontconfig version included in app-emulation/emul-linux-x86-xlibs

Comment 12 Gerold Schellstede 2013-10-26 11:53:06 UTC
I do not understand what "app-emulation/emul-linux-x86-xlibs" has to do with this problem, because the problem depends on the installed version of fontconfig. If acroread uses "emul-linux-x86-xlibs" I would assume that the problem depends on the version of "emul-linux-x86-xlibs" installed. 

Additionally emul-linux-x86-xlibs seems to me as an old style to install 32bit libs. The new way I think is to activate the 32bit-ABI-Flag of fontconfig isn't it?
Comment 13 Samuel Bauer 2013-10-26 21:29:55 UTC
I just come to see that it also uses to create:
$XDG_CACHE_DIR/~/.config/fontconfig directory

don't know if related to the fix I made after reading:

FIX: sed -i '/prefix="xdg"/d' /etc/fonts/fonts.conf

or to:
/etc/fonts/fonts.conf:  <cachedir>~/.config/fontconfig</cachedir>
Comment 14 Pacho Ramos gentoo-dev 2016-03-08 14:23:59 UTC
Please recheck with 9.5.5-r3 as it's finally using a new enough fontconfig version

Thanks for your reply. The problem is gone now. Thanks a lot!
