756 # Revision 1.125 2006/01/04 15:54:55 tipaul
757 # utf8 is a : go for beta test in HEAD.
758 # some explanations :
759 # - updater/updatedatabase => will transform all tables in innoDB (not related to utf8, just to warn you) AND collate them in utf8 / utf8_general_ci. The SQL command is : ALTER TABLE tablename DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci.
760 # - *-top.inc will show the pages in utf8
761 # - THE HARD THING : for me, mysql-client and mysql-server were set up to communicate in iso8859-1, whatever the mysql collation ! Thus, pages were improperly shown, as datas were transmitted in iso8859-1 format ! After a full day of investigation, someone on usenet pointed "set NAMES 'utf8'" to explain that I wanted utf8. I could put this in my.cnf, but if I do that, ALL databases will "speak" in utf8, that's not what we want. Thus, I added a line in Context.pm : everytime a DB handle is opened, the communication is set to utf8.
762 # - using marcxml field and no more the iso2709 raw marc biblioitems.marc field.
764 # Revision 1.124 2005/10/27 12:09:05 tipaul
765 # new features for serial module :
766 # - the last 5 issues are now shown, and their status can be changed (but not reverted to "waited", as there can be only one "waited")
767 # - the library can create a "distribution list". this paper contains a list of borrowers (selected from the borrower list, or manually entered), and print it for a given issue. once printed, the sheet can be put on the issue and distributed to every reader on the list (one by one).
769 # Revision 1.123 2005/10/26 09:13:37 tipaul
770 # big commit, still breaking things...
772 # * synch with rel_2_2. Probably the last non manual synch, as rel_2_2 should not be modified deeply.
773 # * code cleaning (cleaning warnings from perl -w) continued
775 # Revision 1.122 2005/09/02 14:18:38 tipaul
776 # new feature : image for itemtypes.
778 # * run updater/updatedatabase to create imageurl field in itemtypes.
779 # * go to Koha >> parameters >> itemtypes >> modify (or add) an itemtype. You will see around 20 nice images to choose between (thanks to owen). If you prefer your own image, you also can type a complete url (http://www.myserver.lib/path/to/my/image.gif)
780 # * go to OPAC, and search something. In the result list, you now have the picture instead of the text itemtype.
782 # Revision 1.121 2005/08/24 08:49:03 hdl
783 # Adding a note field in serial table.
784 # This will allow librarian to mention a note on a peculiar waiting serial number.
786 # Revision 1.120 2005/08/09 14:10:32 tipaul
787 # 1st commit to go to zebra.
788 # don't update your cvs if you want to have a working head...
790 # this commit contains :
791 # * updater/updatedatabase : get rid with marc_* tables, but DON'T remove them. As a lot of things uses them, it would not be a good idea for instance to drop them. If you really want to play, you can rename them to test head without them but being still able to reintroduce them...
792 # * Biblio.pm : modify MARCgetbiblio to find the raw marc record in biblioitems.marc field, not from marc_subfield_table, modify MARCfindframeworkcode to find frameworkcode in biblio.frameworkcode, modify some other subs to use biblio.biblionumber & get rid of bibid.
793 # * other files : get rid of bibid and use biblionumber instead.
796 # * does not do anything on zebra yet.
797 # * if you rename marc_subfield_table, you can't search anymore.
798 # * you can view a biblio & bibliodetails, go to MARC editor, but NOT save any modif.
799 # * don't try to add a biblio, it would add data poorly... (don't try to delete either, it may work, but that would be a surprise ;-) )
801 # IMPORTANT NOTE : you need MARC::XML package (http://search.cpan.org/~esummers/MARC-XML-0.7/lib/MARC/File/XML.pm), that requires a recent version of MARC::Record
802 # Updatedatabase stores the iso2709 data in biblioitems.marc field & an xml version in biblioitems.marcxml Not sure we will keep it when releasing the stable version, but I think it's a good idea to have something readable in sql, at least for development stage.

814 # Letters / alert system, continuing...
816 # * adding a package Letters.pm, that manages Letters & alerts.
817 # * adding feature : it's now possible to define a "letter" for any subscription created. If a letter is defined, users in OPAC can put an alert on the subscription. When an issue is marked "arrived", all users in the alert will recieve a mail (as defined in the "letter"). This last part (= send the mail) is not yet developped. (Should be done this week)
818 # * adding feature : it's now possible to "put to an alert" in OPAC, for any serial subscription. The alert is stored in a new table, called alert. An alert can be put only if the librarian has activated them in subscription (and they activate it just by choosing a "letter" to sent to borrowers on new issues)
819 # * adding feature : librarian can see in borrower detail which alerts they have put, and a user can see in opac-detail which alert they have put too.
821 # Note that the system should be generic enough to manage any type of alert.
822 # I plan to extend it soon to virtual shelves : a borrower will be able to put an alert on a virtual shelf, to be warned when something is changed in the virtual shelf (mail being sent once a day by cron, or manually by the shelf owner. Anyway, a mail won't be sent on every change, users would be spammed by Koha ;-) )
824 # Revision 1.115 2005/08/02 16:15:34 tipaul
825 # adding 2 fields to letter system :
826 # * module (acquisition, catalogue...) : it will be usefull to show the librarian only letters he may be interested by.
827 # * title, that will be used as mail subject.
829 # Revision 1.114 2005/07/28 15:10:13 tipaul
830 # Introducing new "Letters" system : Letters will be used everytime you want to sent something to someone (through mail or paper). For example, sending a mail for overdues use letter that you can put as parameters. Sending a mail to a borrower when a suggestion is validated uses a letter too.
831 # the letter table contains 3 fields :
832 # * code => the code of the letter
833 # * name => the complete name of the letter
834 # * content => the complete text. It's a TEXT field type, so has no limits.
836 # My next goal now is to work on point 2-I "serial issue alert"
837 # With this feature, in serials, a user can subscribe the "issue alert". For every issue arrived/missing, a mail is sent to all subscribers of this list. The mail warns the user that the issue is arrive or missing. Will be in head.
838 # (see mail on koha-devel, 2005/04/07)
840 # The "serial issue alert" will be the 1st to use this letter system that probably needs some tweaking ;-)
842 # Once it will be stabilised default letters (in any languages) could be added during installer to help the library begin with this new feature.
844 # Revision 1.113 2005/07/28 08:38:41 tipaul
845 # For instance, the return date does not rely on the borrower expiration date. A systempref will be added in Koha, to modify return date calculation schema :
846 # * ReturnBeforeExpiry = yes => return date can't be after expiry date
847 # * ReturnBeforeExpiry = no => return date can be after expiry date

850 # Adding IndependantBranches System preference variable in order to manage Branch independancy.

853 # we have decided that moving to Koha 3.0 requires being already in Koha 2.2.x
854 # So, the updatedatabase script can highly be cleaned (90% removed).
855 # Let's play with the new Koha DB structure now ;-)
