Description Kent Fredric (IRC: kent\n) (RETIRED) gentoo-dev 2017-11-26 07:00:20 UTC 
The test suite enters an infinite loop in t/encoding.t, and needs manual killing. However, the origin of that infinite death loop indicates its probably broken at runtime too.

Line 1190 is:

  1190    print $fh NFC($string);# Unicode NFC boundary


NFC is likely an X-Sub and thus $string is probably undef.

Further poking gives me this backtrace:

Use of uninitialized value in subroutine entry at /var/tmp/portage/dev-tex/biber-2.8-r1/work/biber-2.8/lib/Biber/Utils.pm line 1190.

Biber::Output::test::output(Biber::Output::test=HASH(0x55be9fe5fcb8)) called at t/encoding.t line 231


Temporarily nuking the encoding test makes other tests pass however.

I really don't know what's going on here though, and there's no point in attaching a build log ( it will just fill disk: 

du -sh /var/log/portage-build/build/dev-tex/biber-2.8*

And literally nothing interesting happens before running tests.

I am not able to reproduce this test error. Could you try whether it is still present in the just bumped 2.9?

Still present in 2.9

Comment 3 Hendrik v. Raven 2018-08-08 19:24:02 UTC 
Sorry for ignoring this for so long. Could you check again with 2.10 and also which versions of dev-lang/perl and dev-perl/Text-BibTeX you are using?
Comment 4 Jonas Stein gentoo-dev 2020-04-07 01:50:52 UTC 
No answer yet.
dev-tex/biber-2.8-r1 is no longer in the tree.
Please test and report back with dev-tex/biber-2.12.

biber-2.12 build log

I can't actually replicate this right now for other reasons:

Namely, the test suite fails prolifically for me now, which will have to be fixed in order to see if the "run forever" part still happens.

That is to say: It is far more broken than it was when I tested it last.
