[Fedora-i18n-bugs] [Bug 1809989] New: By default install Noto fonts for Unicode scripts not already covered by default
by bugzilla＠redhat.com 02 Apr '22

https://bugzilla.redhat.com/show_bug.cgi?id=1809989 Bug ID: 1809989 Summary: By default install Noto fonts for Unicode scripts not already covered by default Product: Fedora Version: 31 Status: NEW Component: google-noto-fonts Assignee: petersen(a)redhat.com Reporter: hsivonen(a)hsivonen.fi QA Contact: extras-qa(a)fedoraproject.org CC: fonts-bugs(a)lists.fedoraproject.org, i18n-bugs(a)lists.fedoraproject.org, petersen(a)redhat.com, psatpute(a)redhat.com, pwu(a)redhat.com, tagoh(a)redhat.com Target Milestone: --- Classification: Fedora 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_scrip… 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. -- You are receiving this mail because: You are on the CC list for the bug.

https://bugzilla.redhat.com/show_bug.cgi?id=1784650 Bug ID: 1784650 Summary: Fontconfig is slow, causing stuttering and freezing Product: Fedora Version: 31 Status: NEW Component: fontconfig Severity: high Assignee: tagoh(a)redhat.com Reporter: bepvte+bugzilla(a)gmail.com QA Contact: extras-qa(a)fedoraproject.org CC: ajax(a)redhat.com, caillon+fedoraproject(a)gmail.com, fonts-bugs(a)lists.fedoraproject.org, gnome-sig(a)lists.fedoraproject.org, i18n-bugs(a)lists.fedoraproject.org, john.j5live(a)gmail.com, mclasen(a)redhat.com, pnemade(a)redhat.com, rhughes(a)redhat.com, rstrode(a)redhat.com, sandmann(a)redhat.com, tagoh(a)redhat.com Target Milestone: --- Classification: Fedora 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. -- You are receiving this mail because: You are on the CC list for the bug.

https://bugzilla.redhat.com/show_bug.cgi?id=1677534 Bug ID: 1677534 Summary: texttopaps OOMs with 4GB text file! Product: Fedora Version: rawhide Hardware: x86_64 OS: Linux Status: NEW Component: paps Severity: high Assignee: tagoh(a)redhat.com Reporter: petersen(a)redhat.com QA Contact: extras-qa(a)fedoraproject.org CC: desktop-qa-list(a)redhat.com, eng-i18n-bugs(a)redhat.com, i18n-bugs(a)lists.fedoraproject.org, rhel(a)vlasiu.net, tagoh(a)redhat.com Depends On: 1635160 Target Milestone: --- Classification: Fedora (Cloned from a RHEL7 report) +++ This bug was initially created as a clone of Bug #1635160 +++ Description of problem: Trying to print with cups a 4Gb text file fail. texttopaps consume all the memory and is killed bye the system: [1023082.003989] Out of memory: Kill process xxxx (texttopaps) score 955 or sacrifice child [1023082.005120] Killed process xxxx (texttopaps) total-vm:19958848kB, anon-rss:7531872kB, file-rss:84kB, shmem-rss:0kB /usr/lib/cups/filter/texttopaps 1 user1 "example" 1 "" sample-4Gb.txt --- Additional comment from Akira TAGOH on 2018-10-03 11:54:48 SGT --- Hmm, that log says it all. I don't think OOM is a software bug. --- Additional comment from GV on 2018-10-03 13:00:48 SGT --- Of course OOM is not a software bug. Where exactly did I said that? The problem is texttopaps that allocate memory out of control. texttopaps should allocate memory, use-it, release-it. Like any sane program. The issue was not present on RHEL 6. I had printed the same file multiple times with cups on RHEL6 and it worked just fine (not sure it was texttopaps cups filter involved). Printing the file does not work on RHEL 7 and it should. The 4Gb file is a testcase for our application we develop. --- Additional comment from Jens Petersen on 2018-10-18 17:49:35 SGT --- I don't think the paps in RHEL7 is significantly different from RHEL6. As you say it could be due to changes in Cups? The cups versions in RHEL 6, 7 and Fedora are certainly quite different. Unless texttopaps really worked in RHEL6 it might make to reassign this to cups? --- Additional comment from GV on 2018-10-25 18:29:46 SGT --- Since the real computer running RHEL 6 was already scrapped, I tried to make a virtual machine using RHEL 6. Unfortunately, now I also get a crash on RHEL 6 when printing the 4GB file. I can't recall how much memory was in that computer. The virtual machine had 8Gb of memory allocated. Still, it does not matter that much. I think texttopaps have an issue and it should be fixed or at least an workaround should be available (other than 'don't print a file that large'). I'm afraid this is not a cups issue since I can reproduce the issue running the texttopaps standalone. Sincerely, Gabriel --- Additional comment from Akira TAGOH on 2018-11-16 17:59:04 SGT --- paps isn't supposed to work with large files. to support it, most of code needs to rewritten. this isn't realistic to provide an update for existing products. for a workaround, you can remove paps package (or simply remove /usr/share/cups/mime/paps.convs file) to fall back the text filter to texttops which CUPS originally provides. this should works for this issue and as long as you don't need the internationalization support for printing. Hope that helps. --- Additional comment from GV on 2018-12-07 14:03:33 SGT --- It helps. Thank you!

If you did a dnf system-upgrade from Fedora 30 and were using a bitmap font like Terminus, all your terminals will show the rectangular placeholders the first time you start a terminal. Bitmap fonts like terminus and ucs-miscfixed are much easier to read in a terminal since they are pixel perfect. If Fedora 31 is going to disable support for bitmap fonts, it needs to be announced and the package maintainers of those bitmap font packages are going to need to find a way to convert their fonts. Version-Release number of selected component (if applicable): pango-1.44.6-1.fc31.x86_64 How reproducible: always Steps to Reproduce: 1. install 'terminus-fonts' 2. Start GNOME terminal 3. Open Terminal Preferences 4. Attempt to change the font to Terminus font Actual results: If you upgraded from Fedora 30 and had Terminus fonts as the default font, the first time you launch Terminal, all the text will be the rectangular placeholders. If you search for the Terminus font in the preferences, you won't be able to find it. Expected results: Use the Terminus font as usual Additional info: It appears that pango switched from using FreeType to HarfBuzz, which only supports truetype. I rebuilt the Fedora 30 pango package (1.43) for Fedora 31, downgraded it, and now my terminals are fine showing my bitmap fonts. -- You are receiving this mail because: You are on the CC list for the bug.
