Strange behaviour on Noto fonts.

[EmmanuelCharpentier]

Setup :

Debian testing, font-manager part of Gnome's standard installation. Among fonts :

charpent@zen-book-flip:~$ dpkg -l "*noto*"
Souhait=inconnU/Installé/suppRimé/Purgé/H=à garder

un  fonts-noto-unhinted    <aucune>     <aucune>     (aucune description n'est >

Symptoms :

Various problems when trying to enable/disable some of the Noto fonts (extremely long time of unresponsivity after enabling one font, failure to disable a group of fonts, etc...

When staring font-manager from the command line, I see this :

charpent@zen-book-flip:~$ font-manager 

(font-manager:1657725): [font-manager]-CRITICAL **: 06:10:11.484: font_manager_get_matching_families_and_fonts: assertion 'error == NULL || *error == NULL' failed

(font-manager:1657725): [font-manager]-WARNING **: 06:10:11.484: Disabled.vala:46: Database Error : (SELECT DISTINCT family, description FROM Fonts WHERE family=""Noto";) [1] - near "Noto": syntax error

These two errors appear repeatedly after attempts to act on Noto fonts.

Another (possibly related) problem is that I cannot list the variants of these fonts by clicking on the "right arrowhead" in the list of fonts.

Deleting a spurious ~/.local/share/fonts/Google\ Fonts/ directory which used to contain (a second copy of) Noto\ Sans\ Math/Noto_Sans_Math-Regular.15.ttf (predating my installation of Debian's font-noto-core package) and regenerating both user and system caches with fc-cache -rv didn't fix the problem.

Looks like it might be related to #395

Not sure where our database queries are getting mangled but starting to suspect locale issues.

Can you post the output from locale on your system please.

HTH,

[JerryCasiano]

Nah. Unfortunately it doesn't appear to be related to locale settings.

Another user with similar issues has system set to US English.

Back to the drawing board...

[JerryCasiano]

There's been some changes in master that affect database queries.

If possible build from master to see if it resolves those warnings or makes any difference at all for you.

You'll probably need to also delete the cache folder.

~/.cache/font-manager

To get rid of the existing database files.

[JerryCasiano]

Closing this as there has been no movement and it's unclear whether this still affects the current release.

Feel free to reopen if this is still an issue and you're ready to assist on resolving it by testing changes.
