17 | * History: | ||
18 | * $Log$ | ||
19 | * Revision 1.9 2003/12/22 10:19:26 eilers | ||
20 | * Finishing implementation of sql-backend for datebook. But I have to | ||
21 | * port the PIM datebook application to use it, before I could debug the | ||
22 | * whole stuff. | ||
23 | * Thus, PIM-Database backend is finished, but highly experimental. And some | ||
24 | * parts are still generic. For instance, the "queryByExample()" methods are | ||
25 | * not (or not fully) implemented. Todo: custom-entries not stored. | ||
26 | * The big show stopper: matchRegExp() (needed by OpieSearch) needs regular | ||
27 | * expression search in the database, which is not supported by sqlite ! | ||
28 | * Therefore we need either an extended sqlite or a workaround which would | ||
29 | * be very slow and memory consuming.. | ||
30 | * | ||
31 | * Revision 1.8 2003/09/22 14:31:16 eilers | ||
32 | * Added first experimental incarnation of sql-backend for addressbook. | ||
33 | * Some modifications to be able to compile the todo sql-backend. | ||
34 | * A lot of changes fill follow... | ||
35 | * | ||
36 | * Revision 1.7 2003/08/01 12:30:16 eilers | ||
37 | * Merging changes from BRANCH_1_0 to HEAD | ||
38 | * | ||
39 | * Revision 1.6.4.1 2003/06/30 14:34:19 eilers | ||
40 | * Patches from Zecke: | ||
41 | * Fixing and cleaning up extraMap handling | ||
42 | * Adding d_ptr for binary compatibility in the future | ||
43 | * | ||
44 | * Revision 1.6 2003/04/13 18:07:10 zecke | ||
45 | * More API doc | ||
46 | * QString -> const QString& | ||
47 | * QString = 0l -> QString::null | ||
48 | * | ||
49 | * Revision 1.5 2003/02/21 23:31:52 zecke | ||
50 | * Add XML datebookresource | ||
51 | * -clean up todoaccessxml header | ||
52 | * -implement some more stuff in the oeven tester | ||
53 | * -extend DefaultFactory to not crash and to use datebook | ||
54 | * | ||
55 | * -reading of OEvents is working nicely.. saving will be added | ||
56 | * tomorrow | ||
57 | * -fix spelling in ODateBookAcces | ||
58 | * | ||
59 | * Revision 1.4 2002/10/14 15:55:18 eilers | ||
60 | * Redeactivate SQL.. ;) | ||
61 | * | ||
62 | * Revision 1.3 2002/10/10 17:08:58 zecke | ||
63 | * The Cache is finally in place | ||
64 | * I tested it with my todolist and it 'works' for 10.000 todos the hits are awesome ;) | ||
65 | * The read ahead functionality does not make sense for XMLs backends because most of the stuff is already in memory. While using readahead on SQL makes things a lot faster.... | ||
66 | * I still have to fully implement read ahead | ||
67 | * This change is bic but sc | ||
68 | * | ||
69 | * Revision 1.2 2002/10/08 09:27:36 eilers | ||
70 | * Fixed libopie.pro to include the new pim-API. | ||
71 | * The SQL-Stuff is currently deactivated. Otherwise everyone who wants to | ||
72 | * compile itself would need to install libsqlite, libopiesql... | ||
73 | * Therefore, the backend currently uses XML only.. | ||
74 | * | ||
75 | * Revision 1.1 2002/10/07 17:35:01 eilers | ||
76 | * added OBackendFactory for advanced backend access | ||
77 | * | ||
