85 When a Koha script runs, it makes use of a certain number of things:
86 configuration settings in F</etc/koha/koha-conf.xml>, a connection to the Koha
87 databases, and so forth. These things make up the I<context> in which
90 This module takes care of setting up the context for a script:
91 figuring out which configuration file to load, and loading it, opening
92 a connection to the right database, and so forth.
94 Most scripts will only use one context. They can simply have
100 Other scripts may need to use several contexts. For instance, if a
101 library has two databases, one for a certain collection, and the other
102 for everything else, it might be necessary for a script to use two
103 different contexts to search both databases. Such scripts should use
104 the C<&set_context> and C<&restore_context> functions, below.
106 By default, C4::Context reads the configuration from
107 F</etc/koha/koha-conf.xml>. This may be overridden by setting the C<$KOHA_CONF>
108 environment variable to the pathname of a configuration file to use.
117 # In addition to what is said in the POD above, a Context object is a
118 # reference-to-hash with the following fields:
121 # A reference-to-hash whose keys and values are the
122 # configuration variables and values specified in the config
123 # file (/etc/koha/koha-conf.xml).
125 # A handle to the appropriate database for this context.
127 # Used by &set_dbh and &restore_dbh to hold other database
128 # handles for this context.

981 # Revision 1.54 2007/03/29 16:45:53 tipaul
982 # Code cleaning of Biblio.pm (continued)
984 # All subs have be cleaned :
987 # - reordering Biblio.pm completly
988 # - using only naming conventions
990 # Seems to have broken nothing, but it still has to be heavily tested.
991 # Note that Biblio.pm is now much more efficient than previously & probably more reliable as well.
993 # Revision 1.53 2007/03/29 13:30:31 tipaul
995 # == Biblio.pm cleaning (useless) ==
996 # * some sub declaration dropped
997 # * removed modbiblio sub
998 # * removed moditem sub
999 # * removed newitems. It was used only in finishrecieve. Replaced by a TransformKohaToMarc+AddItem, that is better.

1001 # * removed MARCdelsubfield declaration
1002 # * removed MARCkoha2marcBiblio
1004 # == Biblio.pm cleaning (naming conventions) ==

1011 # * zebraop renamed to ModZebra
1014 # * removing MARC=OFF related scripts (in cataloguing directory)
1015 # * removed checkitems (function related to MARC=off feature, that is completly broken in head. If someone want to reintroduce it, hard work coming...)
1016 # * removed getitemsbybiblioitem (used only by MARC=OFF scripts, that is removed as well)

1170 # my $Zconn = C4::Context->Zconn;
1172 # My initial tests indicate that as soon as your funcion ends
1173 # (ie, when you're done doing something) the connection will be
1174 # closed automatically. There may be some other way to make the
1175 # connection more stateful, I'm not sure...
