Separates per backend type from per backend database initialization and startup. Also supports per type / per backend shutdown. New frontend startup/shutdown routines are also provided: slap_init() slap_startup() slap_shutdown() slap_destroy() New frontend->backend startup/shutdown is managed by: backend_init() backend_startup() backend_shutdown backend_destroy backend_init() now calls bi_init() to initial all function pointers for the backend (excepting bi_init() which is now the only hardcoded entry point). New entry points are detailed in slap.h struct backend_info. backend_info is a per database type structure. Besides the new startup/shutdown entry points, the new interface also supports per backend type configuration options. One could have: backend bdb2 (new Berkeley DB 2 backend) bdb2_home /directory database bdb2 ... *** This code is fairly experimental *** *** Much cleanup and testing is still needed *** see slap.h for details on struct backend_db and backend_info.
