Koha Hackfest in Berlin?
by Mirko Tietgen 08 Jan '16

08 Jan '16

Hello there, European (and other) Koha devs, I am considering hosting a Koha hackfest in Berlin/ Germany next year. It is not supposed to be a counter event to the Hackfest in Marseille nor the Kohacon, but an additional option to meet and work together. It could maybe take place July 2016 (very preliminary date for very preliminary planning), maybe 3 days or the whole week. Before I spend more time fantasizing about it, I'd like your opinion… - do you think it is a good idea (and you would consider joining)? - do you think it is a good idea (but you know you won't join)? - do you think it is not a good idea (given there is a Hackfest in Marseille and Kohacon already, or for other reasons)? - do you think you would have to decide between Berlin and Marseille? - do you think something completely different? No hard feelings if you say Kohacon + Marseille is enough, that would be very valuable feedback. For obvious reasons I would love to hear opinions from Europe (positive or negative), but if coming to Berlin is an option for people from more distant places, I'd love to hear that too. Cheers, Mirko -- Mirko Tietgen mirko(a)abunchofthings.net http://koha.abunchofthings.net http://meinkoha.de

Improving Plack intranet performances (circulation module)
by Julian FIOL 20 Aug '15

20 Aug '15

Hi everyone, Using Devel::NYTProf on a Plack config, I noticed that when we checkout an item in the circulation page, there is a really long time spent creating the database schema. By adding the import of *Koha::Schema* in the *intranet.psgi* file, we can see a significant improvement of the time spent loading the circulation page. Please find here <http://www.slideshare.net/JulianFiol/koha-circulation-checkout-improvement> (in full screen) the proof of what I'm saying. I have also added the manipulations to do into the Plack <http://wiki.koha-community.org/wiki/Plack#Improving_Plack_performance> wiki. Regards, Julian FIOL

Move list related code to Koha::Virtualshelves (Dbix::Class inside)
by Jonathan Druart 19 Aug '15

19 Aug '15

Hello developers, For much of the last 2 days, I have tried to get rid of C4::VirtualShelves::Page, which is, in my opinion, the worst module of Koha [1] I am a bit frustrated because I will be afk for the next 2 weeks and I have not finished what I intended to do. I am still far of removing this module, but I prepared the ground: I have added the package Koha::Virtualshelf, Koha::Virtualshelves, Koha::Virtualshelfshare[s] and Koha::Virtualshelfcontent[s] to take advantage of Dbix::Class. I have also introduced a Koha::Exceptions module to throw exceptions when needed. Of course I have added tests to cover the changes. I did not test widely the interface, so there are certainly some bugs. But for what I tested, it works like as before. It would be interesting to do some benchmarks also. I really would like to get feedbacks on these patches. For those interested in following the evolution of the code and want to share their idea, have a look :) Compare both code (before and after), you will understand why we really need to move/rewrite our code :) I won't be far from my mailbox, don't hesitate to ask [relevant] questions and comment the patch set. Be care, the last patch is a wip ("release early, release often"), don't apply it if you want to test. You will certainly need to update the Dbix::Class schema files. The next steps are: Get rid of GetShelves, GetShelfContents and the other subroutines of C4::Virtualshelves. Then introduce a normal structure to the perl script (shelves.pl and opac-shelves.pl). Finally remove C4::VirtualShelves::Page. Cheers, Jonathan [1] Actually it's not true, there are C4::Context, C4::Auth and C4::Search before :)

Staff: duplicate an item
by Paul A 01 Aug '15

01 Aug '15

I seem to remember (but cannot find) a suggestion? enhancement? to allow cataloguers to duplicate an existing *item*, in the same way that it can be done for biblios "Edit as new (duplicate)". Could some kind soul please point me to any work that has been done on this? Many thanks and regards, Paul

Koha Architecture
by Nicole Engard 30 Jul '15

30 Jul '15

Hi all, I know we've talked about this at conferences from time to time and so I thought I'd share what I learned at one of the keynotes at OSCON. Martin Fowler gave a great talk about internal architecture in our open source projects https://opensource.com/life/15/7/never-neglect-your-projects-architecture and mentioned this article: http://martinfowler.com/bliki/DesignStaminaHypothesis.html I hope these two spark more conversations for us all :) Nicole

Bug 14616 - Introducing Koha::Object subclasses
by Kivilahti Olli-Antti 30 Jul '15

30 Jul '15

Hi there! I haven't found out anywhere where we would actually introduce new Koha::Object subclasses, so I made a bug to collect them. Feel free to add more subclasses here. -- Olli-Antti Kivilahti Järjestelmäkeittäjä vaarakirjastot.fi +358 50 449 7763 --Powered by Kubuntu Linux!

Koha::Object
by Kivilahti Olli-Antti 29 Jul '15

29 Jul '15

Hi there! I was looking for anykind of Interface implementation for Perl, and I found Moose and Class::Interface. I cant but wonder why we are not using Moose for Koha::Object. Apparently it works nicely with DBIx as well. -- Olli-Antti Kivilahti Järjestelmäkeittäjä vaarakirjastot.fi +358 50 449 7763 --Powered by Kubuntu Linux!

Discussion: how to tackle a problem with statistics data
by Tomas Cohen Arazi 29 Jul '15

29 Jul '15

A customer found a problem with statistical reports. They found the circulation stats for returns grouped all returns on the NULL itemtype. What? Well, yes. My first idea was to fill a bug for that [1]. But looking for the bug on the reports code, I found that the problem was in C4::Circulation. So filled a bug for it [2] and provided regression tests and the fix. Cool. But what about the wrong data on the statistics table? Basically, all returns have the wrong itemtype (NULL). Should we fix that table's data? Should we make the report do the proper JOIN operation on the items table? I'd go with the first option, but probably worth discussing, because there are other bugs related to how the 'statistics' table have been filled.
