[Koha-devel] New 'configurations' table (26129)

[Julian Maurice]

Hi Tomas,

I can see the benefits of a per-library, per-itemtype, per-category 
configuration table, but SMTP and Z39.50 servers do not seem to be the 
best example for that : "per-itemtype SMTP servers" does not make sense 
at all, and why would someone need per-library Z39.50 servers ?
Do you have other examples in mind ?

Will the per-category setting rely on the category of the logged-in user 
or the category of the user being worked on (patron checking out an item 
for instance) ? Will it depend on the setting itself (some settings rely 
on the logged-in user, some other settings rely on the user being worked 
on) ? Will it depend on another setting (like item-level_itypes syspref) 
? Will that other setting be configurable per-library ? ...
I'm afraid we will end up with a "configuration hell", even worse than 
what we already have with global system preferences.
At least it should be very clear what each per-thing mean, and we should 
be really careful to not over-complicate configuration.
In this particular example, a `smtp_servers` table seems a lot more simple
