• LibXML-schema.rdf.err

From vladimir on 2020-02-26T16:37:09Z:

This command:

       perl ../owl2soml.pl -voc schema schema.rdf    > schema3.yaml

causes error "Read more bytes than requested. Do you use an encoding-related PerlIO layer? at C:/Strawberry/perl/vendor/lib/XML/LibXML.pm line 882", see LibXML-schema.rdf.err for the full log. This happens with `XML::LibXML` version 2.0132. 

The script is https://github.com/VladimirAlexiev/soml/blob/master/owl2soml/owl2soml.pl

All referenced files (Alien-Build-MM_build.log, LibXML-schema.rdf.err, schema.rdf) are in https://github.com/VladimirAlexiev/soml/tree/master/owl2soml/eg

I tried to upgrade to the latest version 2.0202 (I use cygwin and Strawberry Perl) but got `Installing Alien::Build::MM failed`, see Alien-Build-MM_build.log for the full log.

Hi Vladimir,

I don't see thr Alien*.log file anywhere in the git repo's history. Please provide it.

Sorry!
https://github.com/VladimirAlexiev/soml/blob/master/owl2soml/eg/Alien-Build-MM_build.log
(guess
"log" is auto-ignored by github).
Do you need me to report the version of the libxml library as well? I'm on
cygwin.

Cheers!

Thanks, reported here: https://github.com/Perl5-Alien/Alien-Build/issues/173 .

I've upgraded to the latest `XML::LibXML` version 2.0202, but I still get error "Read more bytes than requested. Do you use an encoding-related PerlIO layer?" I tried with both of these commands, the result is the same.

perl    ../owl2soml.pl -voc schema schema.rdf    2> LibXML-schema.rdf.err
perl -C ../owl2soml.pl -voc schema schema.rdf    2> LibXML-schema.rdf.err

The stack trace is attached. Note: I've removed stuff like this below, which is not related to the problem:

Subroutine spacepad redefined at C:/Strawberry/perl/site/lib/Debug/ShowStuff.pm line 1635.
(in cleanup) 	(in cleanup)  at C:/Strawberry/perl/site/lib/URI/Namespace.pm line 104 during global destruction.

Furthermore, I tried with and without env var PERL_UNICODE=31.
I checked "without" like this, which returns nothing:

  perl -V|grep -i uni

Does the problem still happen? can you share a link to a reproducing code? See https://github.com/shlomif/how-to-share-code-online

Terribly sorry about the huge delay in following this up!

1. Upgraded to XML-LibXML-2.0207:

2. Reproduced like this:

cd soml/owl2soml/eg
perl    ../owl2soml.pl -voc schema schema.rdf    2> LibXML-schema.rdf1.err
perl -C ../owl2soml.pl -voc schema schema.rdf    2> LibXML-schema.rdf2.err

set PERL_UNICODE=31
perl -V|grep -i uni
    PERL_UNICODE="31"

perl    ../owl2soml.pl -voc schema schema.rdf    2> LibXML-schema.rdf3.err
perl -C ../owl2soml.pl -voc schema schema.rdf    2> LibXML-schema.rdf4.err

The result is the same in all 4 cases.
Updated LibXML-schema.rdf.err in the repo (saved just one file)

3. Could please you reproduce by getting
https://github.com/VladimirAlexiev/soml and then repeating the steps above?

cd soml/owl2soml/eg
perl    ../owl2soml.pl -voc schema schema.rdf    2> LibXML-schema.rdf1.err

If not then I can try to make a minimal reproducing code, but I'm not sure
how long that would take me...
