2000-01-19 bertrand <bertrand@helixcode.com> * camel/providers/mbox/camel-mbox-folder.c (_get_message_count): implemented. * camel/providers/mbox/camel-mbox-summary.c (camel_mbox_save_summary): (camel_mbox_load_summary): save/load the next uid. * camel/providers/mbox/camel-mbox-parser.c (camel_mbox_parse_file): Compute the next available uid. * camel/providers/mbox/camel-mbox-folder.c (_create): (_check_get_or_maybe_generate_summary_file): Set and use the next_uid field properly. * camel/providers/mbox/camel-mbox-summary.h: added an extra field to store the next available uid. * camel/providers/mbox/camel-mbox-folder.c (_check_get_or_maybe_generate_summary_file): routine called when the folder is opened. Reads or creates the summary file. (_create): initialize the internal summary structure. (_close): save the summary file on closing. (_init_with_store): initialize mbox specific folder members. svn path=/trunk/; revision=1597
