https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=28230 Bug ID: 28230 Summary: Renewing/Checking out record with Ä or Ö letter in title can make Koha totally unfunctional Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: critical Priority: P5 - low Component: Circulation Assignee: koha-bugs@lists.koha-community.org Reporter: joonas.kylmala@helsinki.fi QA Contact: testopia@bugs.koha-community.org CC: gmcharlt@gmail.com, kyle.m.hall@gmail.com Depends on: 22824 Koha can lock-up/stop working totally (unrelease manual DB LOCK on messages_queue table seems to cause this) in the following example situation (others aswell): - Have a biblio with "Ä" in title - Enable RenewalSendNotice - Enable "Item checkout and renewal" message preference for patron - Checkout an item from biblio "Ä" to patron - Renew the patrons loan and notice the following error:
{UNKNOWN}: YAML::XS::Load Error: The problem:
control characters are not allowed
was found at document: 0 at /kohadevbox/koha/C4/Circulation.pm line 3150
This seems to also cause a lock staying on message_queue table and locking other Koha database transactions from happening. I did some test code to debug this: #use YAML; use Encode; use Data::Dumper; use YAML::XS print Dumper(Dump(YAML::XS::Load(Encode::encode_utf8("---\r\n hello: 'heÄllo'")))); Basically here the YAML::XS version dies but if you replace that with YAML::Load it works. It might also have something to do with the Ä getting double encoded? The code that causes this problem is the
return YAML::XS::Load(Encode::encode_utf8($self->{metadata}));
line in C4::Message::metadata() function. This seems to be caused by "Bug 22824: Replace YAML::Syck with YAML::XS" (d6d01169509999e22).
