In current Fedora Rawhide, KDE network installs fail with a scriptlet error in
an xorg-x11-fonts subpackage:
16:36:01,304 INF dnf.rpm: mkfontscale: error while loading shared libraries:
libfreetype.so.6: cannot open shared object file: No such file or directory
warning: %post(xorg-x11-fonts-ISO8859-1-100dpi-7.5-27.fc34.noarch) scriptlet
failed, exit status 127
16:36:01,310 ERR dnf.rpm: Error in POSTIN scriptlet in rpm package
xorg-x11-fonts-ISO8859-1-100dpi
Dependencies should be in place, AFAICT: xorg-x11-fonts subpackages require
'mkfontdir', which is in the same package as mkfontscale (xorg-x11-font-utils)
and that package requires libfreetype.so.6. What's likely happening is a
dependency loop that dnf has to break somehow. This isn't uncommon on initial
install, something like A requires B requires C requires A, and in order to do
anything, dnf has to pick *some* dependency to disregard. Probably because of
some loop like this, it's ordering install of xorg-x11-fonts-ISO8859-1-100dpi
before install of freetype, and so its %post script fails.
We could look for and try to fix that loop, but note the packaging guidelines
state:
"All scriptlets MUST exit with the zero exit status. Because RPM in its default
configuration does not execute shell scriptlets with the -e argument to the
shell, excluding explicit exit calls (frowned upon with a non-zero argument!),
the exit status of the last command in a scriptlet determines its exit status.
Most commands in the snippets in this document have a “|| :” appended to them,
which is a generic trick to force the zero exit status for those commands
whether they worked or not. Usually the most important bit is to apply this to
the last command executed in a scriptlet, or to add a separate command such as
plain “:” or “exit 0” as the last one in a scriptlet. Note that depending on
the case, other error checking/prevention measures may be more appropriate.
Non-zero exit codes from scriptlets can break installs/upgrades/erases such
that no further actions will be taken for that package in a transaction (see
Ordering), which may for example prevent an old version of a package from being
erased on upgrades, leaving behind duplicate rpmdb entries and possibly stale,
unowned files on the filesystem. There are some cases where letting the
transaction to proceed when some things in scriptlets failed may result in
partially broken setup. It is however often limited to that package only
whereas letting a transaction to proceed with some packages dropped out on the
fly is more likely to result in broader system wide problems."
https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/#_sy...
basically, by policy scriptlets should be written to return 0 even if they
don't work. These scriptlets aren't respecting that. Given that not running
mkfontdir likely doesn't have any calamitous consequences, I think it would
make sense to go with the guidelines and amend all the scriptlets to add `|| :`
at the end (which will cause them to exit 0 even if the command failed).

Correctly Localized Glyphs
Description of problem:
Liberation Fonts do NOT provide full support for Serbian localized glyphs.
Version-Release number of selected component (if applicable):
Liberation-Fonts 2.1-1-1
How reproducible:
You need a program that is able to access the font's localized glyphs: usually
that's LibreOffice Writer.
Steps to Reproduce:
1. Open LibreOffice Writer
2. Type бгдпт, then бгдпт in Italic, бгдпт in Bold and finally бгдпт in Italic
Bold with Liberation Serif, and do the same with Liberation Sans
3. Set the language to "Serbian Cyrillic"
Actual results:
Not all glyphs are correctly localized
Expected results:
See attachment for correctly localized glyphs
Additional info:
Liberation Mono has slanted Italic, therefore only the first glyph should be
localized: CYRILLIC LETTER SMALL BE.

Description of problem:
Summary of dejavu-lgc-sans-mono-fonts is misleading. It is: "A variable-width
Latin-Greek-Cyrillic mono-space font family". Accordingly to Wikipedia:
> A monospaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space. This contrasts with variable-width fonts, where the letters and spacings have different widths.
So, a font is either monospaced or variable-width but not both, these are
mutually exclusive concepts. How dejavu-lgc-sans-mono-fonts can be "a
variable-width mono-space font family"??
Version-Release number of selected component (if applicable):
dejavu-lgc-sans-mono-fonts-2.37-15.fc33
How reproducible:
Always.
Steps to Reproduce:
1. $ dnf info dejavu-lgc-sans-mono-fonts
Actual results:
Summary : A variable-width Latin-Greek-Cyrillic mono-space font family
Expected results:

There is currently movement towards protecting browser users from font
fingerprinting. This means refusing, by default, to load user-installed fonts,
which makes the set of fonts that each OS installs by default even more
important than before.
Firefox bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1582687
W3C CSS WG issue:
https://github.com/w3c/csswg-drafts/issues/4497
Currently, Windows 10, macOS, Android, and Chrome OS provide broader
installed-by-default Unicode coverage than Fedora.
Examples of living scripts that have enough active users to make it to the list
at
https://en.wikipedia.org/wiki/List_of_writing_systems#List_of_writing_scr...
but are not supported by default in Fedora 31 include Javanese, Sundanese,
Batak, Balinese, Mongolian, and New Tai Lue.
Egyptian hieroglyphs is an example of a dead script the Fedora 31 doesn't
support out of the box but Windows 10, macOS, Chrome OS, and Android do.
To remedy this with minimal disk space impact, I suggest the same approach that
Apple took. Apple bundles with macOS those Noto fonts that cover scripts that
were not already covered by the previous installed-by-default set of fonts on
macOS. In the macOS case, the on-disk footprint of the Noto fonts that were
required to take macOS to Android/Chrome OS-competitive Unicode coverage was
only a couple of megabytes. (The fonts are hidden in /Library/Application
Support/Apple/Fonts/Language Support/.) In the case of Fedora, the set of Noto
fonts required to reach the Chrome OS / Android level of script coverage is a
bit larger than in the macOS case but should still be manageable.
Please install, by default, those Noto fonts that provide support for scripts
that are not properly supported by the fonts that Fedora already installs by
default.

[Bug 1784650] New: Fontconfig is slow, causing stuttering and

by bugzilla＠redhat.com

Description of problem:
Fontconfig is much much slower than on other distros, and it stutters or
freezes applications that use it.
Version-Release number of selected component (if applicable):
Name : fontconfig
Version : 2.13.92
Release : 3.fc31
Architecture: x86_64
How reproducible:
I can reproduce this bug on a fresh Fedora 31 vm with the Xfce desktop and
google-noto-sans-* fonts installed.
Steps to Reproduce:
1. dnf install google-noto-sans-*
2. run gedit on the attached example file
alternatively
1. dnf install google-noto-sans-*
2. open firefox and browse to https://www.wikidata.org/wiki/Q52 (page with lots
of languages)
Actual results:
It takes around 60 seconds for gedit to become responsive to scrolling and
input. Mousepad is faster but still slow.
It takes firefox upwards of 5 minutes to get to first paint on a page with many
fonts or languages, compared to a simpler page.
Expected results:
Gedit should load files with many fonts at a similar speed as other distros.
The page should load quickly, like on Debian and others.
Additional info:
I have tried to diagnose the source of this issue in many ways.
Running `perf trace` on what sysprof indicated was the most busy function
(FcStrCmpIgnoreCaseAndDelims), shows that every name of every font family is
being compared to every other name of every other font family. I do not know if
this is a normal behaviour of fontconfig.
I have noticed the amount of calls to "FcStrCmpIgnoreCaseAndDelims" and program
startup time both drop to a similar amount as Debian's when all of the
"google-noto" configuration files in /etc/fonts/conf.d/ are deleted (These
files are not present in Debian). However, this might not be the source of the
problem:
In the Debian vm, with a copy of my computer's /etc/fonts/, including the
google-noto files, (I took care to ensure that there would be no broken
symlinks) and /usr/share/fonts, fontconfig does not stall any programs. The
amount of calls to FcStrCmpIgnoreCaseAndDelims is also much lower as well.
This led me to believe that it was a difference caused by compiler flags but
this does not seem to be the case. I tried to replace the optflags in the
package, except for the rpmbuild required debug ones, and found no difference.
I also checked to ensure that it was not caused by GCC version differences.
Debian results for mousepad:
1,845,449 calls to FcStrCmpIgnoreCaseAndDelims
Time: 5 seconds
Fedora results for mousepad:
11,658,380 calls to FcStrCmpIgnoreCaseAndDelims
Time: 23 seconds
https://perfht.ml/2tleJxN
Here is a link to a Firefox profiler result of the wikidata page, where in the
flame graph you can see that Firefox is spending most of its time in
fontconfig. You can also see "FirstNonBlankPaint" is at 50 seconds in the
marker table.
TLDR: Fontconfig matching is slow with all google-noto fonts installed, unless
you remove the noto config files. Using the same exact font directory and
config directory (including the noto config files) on Debian does not cause the
same problem.

With the transition to new forge-based fonts macros, the -common subpackage was
dropped, but some packages depend on that. They are now not installable on
fedora 32+ because that package is gone (only Obsoleted, not Provided).
This affects at least python3-weasyprint.
Additionally, the sdljava-demo package now has broken dependencies as well:
- /usr/share/fonts/dejavu/DejaVuSans-Bold.ttf
- /usr/share/fonts/dejavu/DejaVuSans-BoldOblique.ttf
- /usr/share/fonts/dejavu/DejaVuSans-Oblique.ttf
- /usr/share/fonts/dejavu/DejaVuSans.ttf
Probably those files were renamed with the forge macro transition.

Description of problem:
I have this (per-user) fontconfig configuration to set my preferred sans-serif
font:
<alias>
<family>sans-serif</family>
<prefer>
<family>Noto Sans</family>
<family>Noto Sans CJK SC</family>
</prefer>
</alias>
It should fall back to "Noto Sans CJK SC" when displaying CJK characters. Since
F32 this isn't working anymore. CJK characters are rendered in a different
font, which I cannot recognize.
Digging through fc_debug logs, "Droid Sans" is appended right after "Noto
Sans", before "Noto Sans CJK SC" in the font matching list. Debug messages
confirm it's indeed Droid Sans getting picked.
Removing the relevant part in /etc/fonts/conf.d/65-google-droid-sans-fonts.conf
mitigates this issue. However since both Noto Sans & Droid Sans do not contain
CJK characters, they should both be skipped in favor of CJK fonts. Could this
be a metadata problem? i.e. Droid Sans wrongly advertises as CJK capable.
