1st draft for MARC biblio deletion.
Still does not work well, but at least, Biblio.pm compiles & it should'nt break too many things
(Note the trash in the MARCdetail, but don't use it, please :-) )
I changed this behaviour :
if notforloan is set for a given item, and NOT for all items from this itemtype, the notforloan is kept.
If notforloan is set for itemtype, it's used (and impossible to loan a specific item from this itemtype)
This supports is only for MARC <-> OLD-DB link. It worked previously, but values entered as MARC were not reported to OLD-DB, neither values entered as OLD-DB were reported to MARC.
Note that some OLD-DB subs are strange (dummy ?) see OLDmodsubject, OLDmodsubtitle, OLDmodaddiauthor in C4/Biblio.pm
For example it seems impossible to have more that 1 addi author and 1 subtitle. In MARC it's not the case. So, if you enter more than one, I'm afraid only the LAST will be stored.
z3950 search and import seems to works fine.
Let me explain how :
* a "search z3950" button is added in the addbiblio template.
* when clicked, a popup appears and z3950/search.pl is called
* z3950/search.pl calls addz3950search in the DB
* the z3950 daemon retrieve the records and stores them in z3950results AND in marc_breeding table.
* as long as there as searches pending, the popup auto refresh every 2 seconds, and says how many searches are pending.
* when the user clicks on a z3950 result => the parent popup is called with the requested biblio, and auto-filled
Note :
* character encoding support : (It's a nightmare...) In the z3950servers table, a "encoding" column has been added. You can put "UNIMARC" or "USMARC" in this column. Depending on this, the char_decode in C4::Biblio.pm replaces marc-char-encode by an iso 8859-1 encoding. Note that in the breeding import this value has been added too, for a better support.
* the marc_breeding and z3950* tables have been modified : they have an encoding column and the random z3950 number is stored too for convenience => it's the key I use to list only requested biblios in the popup.
It was due to an illegal contruction in Koha : we tried to retrive subfields from <10 tags.
That's not possible. MARC::Record accepted this in 0.93 version, but it was fixed after.
Now, the construct/retrieving is OK !
* worked in 1.9.0, but not in 1.9.1 :
- modif of a biblio didn't work
- empty fields where not shown when modifying a biblio. empty fields managed by the library (ie in tab 0->9 in MARC parameter table) MUST be entered, even if not presented.
* did not work before :
- repeatable subfields now works correctly. Enter 2 subfields separated by | and they will be splitted during saving.
- dropped the last subfield of the MARC form :-(
Internal changes :
- MARCmodbiblio now works by deleting and recreating the biblio. It's not perf optimized, but MARC is a "do_something_impossible_to_trace" standard, so, it's the best solution. not a problem for me, as biblio are rarely modified.
Note the MARCdelbiblio has been rewritted to enable deletion of a biblio WITHOUT deleting items.
Those fields doesn't have subfields.
In koha, we will use a specific "trick" : fields <10 will have a "virtual" subfield : "@".
Note it's only virtual : when rebuilding the MARC::Record, the koha API handle correctly "@" subfields => the resulting MARC record has a 00x field without subfield.
