2004-03-23 Not Zed <NotZed@Ximian.com> * camel-exception.c (camel_exception_setv): use camel debug to add some debug here. * camel.c (camel_init): call camel_debug_init(). * camel-debug.c (camel_debug_init, camel_debug): new util stuff for extended debug options. * providers/imap/camel-imap-folder.c (imap_get_message): if we're supposed to be online, check we are online before proceeding. Actually major restructure so we re-try the fetch a couple of times first before failing. i.e. silent reconnect. See #55381. svn path=/trunk/; revision=25153
