804.035 doesn't help, same test failures, both on F32 and F33. F31 is okay.

The problem is probably related to the fonts update. 

Notes from Tk-804.035/README:

* There are a lot more tests in Tk804. Some notably t/entry.t and
t/listbox.t very dependant on the available fonts and to a lesser
extent the window manager used. 

* By default Perl/Tk makes use of client side fonts via freetype2,
fontconfig and Xft on Unix systems. This gives anti-aliased fonts for
regular text (if you have TrueType or Type1 fonts and they are in your
fontconfig config file). See also http://fontconfig.org .
To disable this feature run the Makefile.PL
with "perl Makefile.PL XFT=0".

I tried to build Tk-804.035 with XFT=0 and the package was build successfully.

I am preparing rebuild for Perl 5.32.

May I update the package to Tk-804.035 and change XFT from 1 to 0?

Sure, please go ahead.

I don't think so. Building it by hand, with XFT=1 and either doing "make test" or running the unit test alone:


   $ perl -It -MTkTest -e "checked_test_harness('./xt', 0, 'blib/lib', 'blib/arch')"  t/entry.t 
   t/entry.t .. ok       
   All tests successful.
   Files=1, Tests=351,  2 wallclock secs ( 0.04 usr  0.01 sys +  2.10 cusr  0.03 csys =  2.18 CPU)
   Result: PASS

Works.

The only difference I see is that, when building with mock, the output is not displayed. I'm starting to suspect that the unit test is failing due to some limitation at mock to emulate a X11/Wayland console, e. g. probably some incompatibility with xorg-x11-server-Xvfb.

Funny enough, running:

   xvfb-run -a perl -It -MTkTest -e "checked_test_harness('./xt', 0, 'blib/lib', 'blib/arch')"  t/entry.t

or

   xvfb-run -a make test

works fine too. Perhaps it requires some extra package for the tests to pass on mock?

Ok, with this small patch:

diff --git a/t/entry.t b/t/entry.t

It can be seen the differences between a build on a machine with X11 properly installed:

  $  perl -It -MTkTest -e 'checked_test_harness('\''./xt'\'', 0, '\''blib/lib'\'', '\''blib/arch'\'')' t/entry.t

And a build with mock:

I suspect that some additional packages are required for the adobe-currier font, libXft and fontconfig to be properly installed/initialized inside mock chroot.

Found it!

events.t requires google-noto-sans-fonts in order to pass. I'll enclose a patch on this BZ.

Created attachment 1729853 [details]
Re-enable TrueType support by adding a missing font

I doubt google-noto-sans-fonts is the cause. This package predates Noto font. Also you can see that the font is not listed in the installed package set <https://kojipkgs.fedoraproject.org//packages/perl-Tk/804.034/8.fc32/data/logs/x86_64/root.log> for the last successful build before the XFT was disabled. I'd rather bet on FontConfig cache not being updated or the metrics of the exhibited font being removed or moved to a different package. Also note that -adobe-courier-medium-r-normal--12-120-75-75-m-*-iso8859-1 is the old non-FT font specification. So if indeed that font was used, then no XFT was involved.

I tested installing xorg-x11-fonts-ISO8859-1-75dpi, which should be carrying adobe-courier font, but installing it didn't make any change.

I agree that this could be due to FontConfig cache, but it could also be due to some font replacement setup that would happen when this font is installed.

In either case, before coming up with this solution, I tried to install other packages that would make more sense, but everything failed until this one got installed. After installing it, mock was able to successfully the package on both Fedora 33 and rawhide.

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.
