** For bug #31647 and bug #31456.

2002-10-24  Not Zed  <NotZed@Ximian.com>

        ** For bug #31647 and bug #31456.

        * camel-store-summary.c (store_info_string): for STORE_INFO_NAME,
        skip the leading /.

        * providers/imap/camel-imap-store.c
        (parse_list_response_as_folder_info): Remove jeff's last patch,
        and use the store summary to create the name and path of the
        folderinfo so it manages namespace issues.
        (get_folder_info_online): Just pass @top directly to
        build_folder_info always, since namespace is mapped to 1 tree
        level.
        (imap_build_folder_info): Remove jeff's last patch, dont strip
        leading /'s, they shouldn't exist.
        (imap_connect_online): Remove adding the INBOX here, we add it
        later.
        (get_subscribed_folders): Make sure INBOX is always in the list.
        some imap servers dont seem to let you subscribe to it(?), so
        always have it act as subscribed.

        * camel-store.c (camel_folder_info_build): back out the last 2
        patches from Jeff (for #31456) to get the original behaviour.
        (camel_folder_info_build): When creating a fake
        parent, dont strip the namespace from the full_name.  malloc keys
        in hash since we dont have them anymore.
        (free_name): Helper to free names.

        * providers/imap/camel-imap-store-summary.c
        (camel_imap_store_summary_namespace_new): Canonicalise the
        namespace (strip trailing dir_sep), and change the path to remove
        any /'s.
        (camel_imap_store_summary_namespace_find_path):
        (camel_imap_store_summary_namespace_find_full): new, find
        namespace by path/full name.
        (camel_imap_store_summary_full_from_path): Changed to a simple
        wrapper around path_to_full, after checking namespace.
        (camel_imap_store_summary_add_from_full): map the namespace if
        present.
        (camel_imap_store_summary_path_to_full): If namespace exists,
        unmap it.
