Get message count when STATUS is not available. (imap_init):
2000-07-28 Jeffrey Stedfast <fejj@helixcode.com> * providers/imap/camel-imap-folder.c (imap_get_message_count_internal): Get message count when STATUS is not available. (imap_init): folder->has_search_capability is required for IMAP so should always be set to TRUE (is currently being set to FALSE as I've not yet implemented SEARCH support). (camel_imap_folder_changed): Seem to have fixed my optimization hack 2000-07-28 Jon K Hellan <hellan@acm.org> * providers/imap/camel-imap-store.h (CamelImapServerLevel): New enum. (CamelImapStore): Added server_level and has_status_capability members. * providers/imap/camel-imap-store.c (imap_connect): Detect IMAP4REV1, IMAP4 and STATUS in capability response. * providers/imap/camel-imap-folder.c (imap_get_message_count_internal): Use STATUS only if server supports it. TODO: Get message count when STATUS not supported. (imap_get_message, imap_get_summary_internal, imap_get_message_info_internal): Handle IMAP4 as well. (imap_protocol_get_summary_specifier): New function: Make a data item specifier for the header lines we need, appropriate to the server level. svn path=/trunk/; revision=4406
