* some bugfixes
* multiple item management : MARCadditem and MARCmoditem have been added. They suppose that ALL the MARC field linked to koha-item are in the same MARC tag (on the same line of MARC file)
Note : it should not be hard for marcimport and marcexport to re-link fields from internal tag/subfield to "legal" tag/subfield.
Database.pm and Output.pm are almost not modified (var test...)
Biblio.pm is almost completly rewritten.
WHAT DOES IT ??? ==> END of Hitchcock suspens
1st, it does... nothing...
Every old API should be there. So if MARC-stuff is not done, the behaviour is EXACTLY the same (if there is no added bug, of course). So, if you use normal acquisition, you won't find anything new neither on screen or old-DB tables ...
All old-API functions have been cloned. for example, the "newbiblio" sub, now has become :
* a "newbiblio" sub, with the same parameters. It just call a sub named OLDnewbiblio
* a "OLDnewbiblio" sub, which is a copy/paste of the previous newbiblio sub. Then, when you want to add the MARC-DB stuff, you can modify the newbiblio sub without modifying the OLDnewbiblio one. If we correct a bug in 1.2 in newbiblio, we can do the same in main branch by correcting OLDnewbiblio.
* The MARC stuff is usually done through a sub named MARCxxx where xxx is the same as OLDxxx. For example, newbiblio calls MARCnewbiblio. the MARCxxx subs use a MARC::Record as parameter.
The last thing to solve was to manage biblios through real MARC import : they must populate the old-db, but must populate the MARC-DB too, without loosing information (if we go from MARC::Record to old-data then back to MARC::Record, we loose A LOT OF ROWS). To do this, there are subs beginning by "ALLxxx" : they manage datas with MARC::Record datas. they call OLDxxx sub too (to populate old-DB), but MARCxxx subs too, with a complete MARC::Record ;-)
In Biblio.pm, there are some subs that permits to build a old-style record from a MARC::Record, and the opposite. There is also a sub finding a MARC-bibid from a old-biblionumber and the opposite too.
Note we have decided with steve that a old-biblio <=> a MARC-Biblio.
Not related to MARC :
* removed HLT- empty link when no basket for a supplier (should be useful to copy this into rel-1-2 i think)
* fixed some "use of uninitialized value"
related to MARC
* changed use Acquisition to use Catalogue, new package for MARC management
For instance, nothing is done to MARC DB, but structure is modified (see Biblio.pm for details), and everything seems to work : it's still possible to use acqui, and it fills old-DB pretty good.
WARNING : if you work on main trunk, please note Acquisition.pm is NO MORE USED in /acqui/ system. Every sub in Acquisition.pm has been moved to Biblio.pm or Catalogue.pm.
0- Requires MARC::Record from cpan to work
1- divided Catalogue.pm in 2 parts :
Biblio.pm ,that contains biblio management
Catalogue.pm, that contains acquisition management.
When ended, they will replace the Acquisition.pm package
2- Created MARCxxx functions :
* MARCgetbiblio : retrieves a MARC::Record from the bibid passed in parameter (working, see test.pl script)
* MARCaddbiblio : creates a MARC-DB entry, for a MARC::Record given as parameter. (working)
* MARCmodsubfield : modifies a subfield for a given subfieldid
* MARCfingsubfield : retrieves a subfieldvalue from a bibid/tag/subfield
* MARCaddsubfield : adds a subfield to biblio into the DB
* MARCkoha2marc : builds a MARC::Record, given a biblionumber, a biblioitemnumber and/or an itemnumber. (working).
TODO :
A lot ;-))))
For instance, you can create only a MARC-DB entry from a old-DB entry. Note some questions are still to solve around bibid (old-DB/MARC-DB)...
