Test failures in poppler-qt5 #1049

Closed NHOrus closed 7 months ago

NHOrus commented 7 months ago

https://bugs.gentoo.org/895268 Test log attached.

Poppler 24.03.0, texworks-0.6.9, but was observed with 0.6.8

LastTest.log Is this failure safe to ignore e.g. caused by poppler changes?

stloeffler commented 7 months ago

I think this may be related to missing fonts on the system running the test. According to the PDF specs, all viewers must ensure that 14 base fonts are provided by the system (i.e., they must be displayed correctly even if they are not embedded in the pdf file itself). This test covers exactly that (in particular the ZapfDingbats case which is the one causing most problems). Could you try installing the urw-fonts and see if that fixes the problem? (NB: If it does, urw-fonts should be a mandatory dependency of the texworks package (both for building and using) to comply with the PDF standard)

Fonts were installed before test failure. urw-fonts 20230503

Interesting. In case of the failures you mentioned, the test code saves the problematic renders. In your case, the log indicates that they are saved as /var/tmp/portage/app-editors/texworks-0.6.9/temp/test_poppler-qt5.* with random extensions.

Could you

Okay. Fontconfig is messed up.

Should this be better?

NHOrus commented 7 months ago

Yeah, with that it is better.

Thank you for pointing me to solution.

Solution, for Gentoo people: in eselect-fontconfig enable:

  [49]  61-urw-bookman.conf *
  [50]  61-urw-c059.conf *
  [51]  61-urw-d050000l.conf *
  [52]  61-urw-fallback-backwards.conf *
  [53]  61-urw-fallback-generics.conf *
  [54]  61-urw-fallback-specifics.conf *
  [55]  61-urw-gothic.conf *
  [56]  61-urw-nimbus-mono-ps.conf *
  [57]  61-urw-nimbus-roman.conf *
  [58]  61-urw-nimbus-sans.conf *

  [60]  61-urw-standard-symbols-ps.conf *
  [61]  61-urw-z003.conf *

after which tests pass.

You're welcome, glad I could help. That's exactly the kind of situation the test was written for.
