Package: ttf-dejavu
Version: 2.28-1
Severity: normal
After upgrading ttf-dejavu cyrillic text in iceweasel bacame unreadable
(letters are still
Cyrillic, and readable, but words look like made with random password
generator), that
was fixed after restarting iceweasel.
It can be bacause:
1. Font was open by Iceweasel and during upgrade it was overwritten in-place
(instead of creating temporary file and then moving it, iceweasel could use
deleted file with old contents)
2. Information about glyph offsets/numbers is cached somewhere (Iceweasel,
freetype...),
and is not updated after font upgrade. And then new file was opened and
cached
information was used to get glyphs from it.
3. Fontconfig caches were overwritten in-place during upgrade.
4. Iceweasel keeps font files open, but reads fontconfig caches time-to-time.
lsof shows that iceweasel keeps ttf files open, and I think dpkg does not
overwrite files
in-place, so this is probably case 3. But I dont have time now to ivestigate
further.
This bug probably not specific to ttf-dejavu/iceweasel/Cyrillic glyphs, and
probably
can be reproduced with fonts that change significantly during upgrade.

Version: 115.12.0esr-1+rm
src:iceweasel has been superseded by src:firefox-esr in version
45.0esr-1 in March 2016. Transitional packages to ease upgrades were
provided in the wheezy, jessie, stretch and buster releases. The
transitional packages have been removed finally before the bullseye
release in August 2021.
After regular security support for buster ended in August 2022 and LTS
support ended in June 2024, I'm closing the remaining bug reports now.
