Actually, if you can capture a stack trace of Emacs, that may tell us what part of Fontconfig to look at if we want to change it to gracefully handle stale cache entries.

Profile hooks are normal derivations; as such, they don’t have access to anything but their dependencies and their output(s). There’s currently no infrastructure to run arbitrary code upon package installation (which I think is a feature more than a bug :-)). We could make an exception, but it’s kinda ugly. I wonder if, instead, we could have Fontconfig realize that the cache is stale somehow. Alternately, we could generate the cache in a profile hook and have Fontconfig use that cache instead of the one in ~/.cache. However, Fontconfig would need to be able to: 1. Be told which cache to use, not just the one from ~/.guix-profile, so that it works equally well with other profiles. 2. Merge several caches, so it can also account for fonts installed in /run/current-system/profile. We discussed all this several times in the past but I don’t think it went further.

That's possible since adding support to XDG_DATA_DIRS in fontconfig itself (see c738a054cac00441a4f697f0b40705d0b3f4a7a7, "gnu: fontconfig: Add a search path for XDG_DATA_DIRS."). > 2.

There was also something contributed that should have improved/fix cache invalidity in 6f12880a76a6c91058718d15845f8b9d9b529a5a ("gnu: fontconfig: Use (locally) deterministic caching"). I haven't seen this problem in a long while, so I'm inclined to think it's been resolved. -- Thanks, Maxim ^ permalink raw reply [flat|nested] 9+ messages in thread

I think I had that issue with a fresh install within the last year and based on advice in IRC (thanks nckx!) ran 'fc-cache -fv'. For what it's worth, I believe Debian's packaging tools (in this case, Debhelper) detect changes to the font directories and add a font update hook to the package installation scripts. Since we do not have such scripts—and I am with Ludo' that it's probably a feature worth preserving—maybe our package manager could run the hook?

OK, thanks for the information; let's leave this bug open then. > For what it's worth, I believe Debian's packaging tools (in this case, > Debhelper) detect changes to the font directories and add a font > update hook to the package installation scripts.

Another idea: modify fontconfig so that it never creates or uses cache. Revisit later if it causes performance problems (I doubt it would). -- Thanks, Maxim ^ permalink raw reply [flat|nested] 9+ messages in thread
