Hi Jonathan,
I think it's the latest version available: 16.05.04.001. The local
changes are focused on authorities searching as I think, but I'm not
absolutely sure (isn't my work). It's just my opinion that about the
local changes, so we didn't try to run without it - in addition it's a
bit difficult to turn it off on production systems. I would appreciate
any information regarding plack, which might be missed during our
development process. Is there any reason why "undefined subroutine"
error raises because of plack? PLease remember, the restart always fixes
the problem as well as prefixing the procedure name. But the question
is: WHY?
Cheers,
Radek

Hi Radek,
Which version of Koha are you running on? What are you local changes?
Did you try without?
Cheers,
Jonathan

Hi,
sometimes we are facing very annoying problem concerning Z39.50
searching, bacause all attempt to search records fail with a
"white page of death" saying only "Internal server error". It is
somehow connected to plack, but we cannot find a good solution.
Symptoms:
# tail plack-error.log -n 5
Undefined subroutine &C4::Breeding::GetZ3950BatchId called at
/usr/share/koha/lib/C4/Breeding.pm line 279.
Undefined subroutine &C4::Breeding::GetZ3950BatchId called at

/usr/share/koha/lib/C4/Breeding.pm line 279.
Solution A:
# koha-plack --restart
When we restart the plack service, then the searching starts to
work again for an unpredictable period of time (often several
days, sometimes week or two).
Solution B:
We add a "C4::ImportBatch::" prefix to C4/Breeding.pm at these two
lines:
my $batch_id = GetZ3950BatchId($servhref->{servername});
my $breedingid = AddBiblioToBatch($batch_id, $seq, $marcrecord,
'UTF-8', 0, 0);
This solution works well except the fact, that prefixing is not
probably the best idea because the procedures SHOULD be already
imported. In fact, they aren't. Sometimes.
We think it could be caused by our local changes of code. We are
not happy with it, but is it possible that the local changes of
code don't work well with plack module? What should be kept in
mind to avoid (probably?) incorrect imports with "use" command?
Thanks a lot!
Radek
