Subject: XML Test in Net-DAV-Server broken
When updating XML-LibXML I always run the tests of all modules depending on it. Changing vom XML-LibXML-2.0129 to 2.0130 makes two tests of Net-DAV-Server-1.305 fail. 2.0131 has the same problem. The problematic tests are t/server_propfind.t and t/server_propfind_lock.t. I have looked into t/server_propfind.t. Subtest 9 parses an XML file with $parser->parse_string( $content ). Parser is a XML::LibXML object, error message is: Unable to parse content: :2: namespace error : Failed to parse QName 'D:D:' <D:D:multistatus xmlns:D="DAV:"><D:response><D:href>/foo/</D:href><D:propstat><D ^ The content is generated with Net::DAV::Server->propfind(). my $doc = XML::LibXML::Document->new( '1.0', 'utf-8' ); my $multistat = $doc->createElement('D:multistatus'); $multistat->setAttribute( 'xmlns:D', 'DAV:' ); $doc->setDocumentElement($multistat); ... $response->content( $doc->toString(0) ); With XML-LibXML-2.0129 the content is: <?xml version="1.0" encoding="utf-8"?> <D:multistatus xmlns:D="DAV:"><D:response><D:href>/foo/</D:href><D:propstat><D:prop><D:creationdate>2017-10-25T13:21:33</D:creationdate><D:getcontentlength/><D:getcontenttype>httpd/unix-directory</D:getcontenttype><D:getlastmodified>Wed, 25 Oct 2017 13:21:33 GMT</D:getlastmodified><D:supportedlock><D:lockentry><D:lockscope><D:exclusive/></D:lockscope><D:locktype><D:write/></D:locktype></D:lockentry></D:supportedlock><D:resourcetype><D:collection/></D:resourcetype></D:prop><D:status>HTTP/1.1 200 OK</D:status></D:propstat></D:response></D:multistatus> With XML-LibXML-2.0131 it changed to: <?xml version="1.0" encoding="utf-8"?> <D:D:multistatus xmlns:D="DAV:"><D:response><D:href>/foo/</D:href><D:propstat><D:prop><D:creationdate>2017-10-25T13:45:11</D:creationdate><D:getcontentlength/><D:getcontenttype>httpd/unix-directory</D:getcontenttype><D:getlastmodified>Wed, 25 Oct 2017 13:45:11 GMT</D:getlastmodified><D:supportedlock><D:lockentry><D:lockscope><D:exclusive/></D:lockscope><D:locktype><D:write/></D:locktype></D:lockentry></D:supportedlock><D:resourcetype><D:collection/></D:resourcetype></D:prop><D:status>HTTP/1.1 200 OK</D:status></D:propstat></D:response></D:D:multistatus> The D:D: namespace looks wrong.

I am tempted to believe this code should not have worked properly in the first place, and that it was an accidental feature that it did. Can you provide a http://sscce.org/ for it as a Test::More test script and attach it here? Show quoted text

I have no strong opinion whether XML-LibXML or Net-DAV-Server is wrong. My goal is to update the Perl modules in the OpenBSD ports tree, but I see tests failing when doing that. I started with a bug report here as the update to XML-LibXML-2.0130 made the test fail. I seems strange to me that XML::LibXML cannot parse its own output. If the API is misused by Net-DAV-Server, XML-LibXML should report an error when creating the document. Show quoted text

This script passes with XML-LibXML-2.0129 and fails with 2.0131: use strict; use warnings; use XML::LibXML; use Test::More tests => 8; ok(my $doc = XML::LibXML::Document->new(), 'new document'); ok(my $elm = $doc->createElement('D:element'), 'create element'); ok($elm->setAttribute('xmlns:D', 'attribute'), 'set attribute'); $doc->setDocumentElement($elm); # XXX does not return true if successful ok(my $str = $doc->toString(0), 'to string'); ok(my $par = XML::LibXML->new(), 'new parser'); ok( eval { $par->parse_string($str) } , 'parse string'); is($@, "", 'parse error'); like($str, qr{<D:element xmlns:D="attribute"/>}, 'xml element');

I found a number of other CPAN distributions broken by the recent XML::LibXML versions. See the RT links.

Hi! please try again with 2.0132 - I reverted a commit that broke your test while adding your test file as a regression test for the future.

2.0132 indeed looks better --- the four broken distributions I found so far work again: - Net-DAV-Server-1.305 - Tree-Template-Declare-0.7 - Bio-Phylo-0.58 - PRANG-0.20
