Description Petr Pisar 2021-05-17 07:30:51 UTC
perl-HTML-TreeBuilder-LibXML-0.26-18.fc35 fails to build in Fedora 35 because a test fails:

$ perl -Ilib t/05_empty.t
1..15

#   Failed test at t/05_empty.t line 18.

#   Failed test at t/05_empty.t line 18.
#                   ''
#     doesn't match '(?^:<html>)'
# Looks like you failed 3 tests of 15.

A difference between passing and failing build root is at <https://koschei.fedoraproject.org/build/10320715>. The failure is triggered by upgrading libxml2 from 2.9.10-12.fc35 to 2.9.12-1.fc35.

Comment 1 Emmanuel Seyman 2021-06-14 14:49:19 UTC
The test fails because HTML::TreeBuilder::LibXML returns an empty string while the test expects something containing <html>.

Looking at HTML::TreeBuilder::LibXML::Node::as_HTML(), it calls toStringHTML(), falls back on XML::LibXML::Node::toStringC14N() and finally on XML::LibXML::Node::toString(). In the case of an empty string, toStringHTML() cannot be called and, while XML::LibXML::Node::toString() returns '<html><body/></html>', XML::LibXML::Node::toStringC14N() returns an empty string without errors (so this ends up being used).

Hummm...
