Due to the introduction of mail_folder_cache_remove(), we can no longer
2001-08-30 Peter Williams <peterw@ximian.com> Due to the introduction of mail_folder_cache_remove(), we can no longer assume that mail_folder_info's always exist, so we need to robustify a lot of this. * mail-folder-cache.c (folder_browser_destroyed): New function. Called when the folder browser is destroyed -- analogous to camel_folder_finalized. (mail_folder_cache_note_fb): Hook it up here. (struct _mail_folder_info): Add a member, mail_info_id, that records the get_mail operation's id, so that we can cancel it if we need to. (get_folder_info): Initialize it here. (get_mail_info_reply): Clear it here. (mail_folder_cache_remove_folder): If necessary, cancel it here. (mail_folder_cache_note_folder): Check it here before starting a new operation, just in case. (update_message_counts_main): Take a URI instead of a mail_folder_info *, in case the MFI has gotten destroyed. (update_message_counts): Take a quark of the URI instead of a mail_folder_info *, for the same reason. We use a quark instead of an allocated gchar * because figuring out when to free the string gets tricky. Then go from quark -> URI string -> MFI. Return if the folder is no longer valid, because this indicates that the MFI was removed before this signal got called. Pass a string to update_message_counts_main instead of an MFI. (camel_folder_finalized): Don't bother unhooking the signals here. Same change as above, but don't bother checking for a valid folder because we're about to make it invalid anyway. (message_list_built): Analogous to the above, except with the FolderBrowser instead of the CamelFolder. (selection_changed): As above. (folder_browser_destroyed): As above. (struct get_mail_info_msg): Instead of taking a mail_folder_info *, take a URI, for reasons explained above. (get_mail_info_receive): Go from URI -> MFI before doing anything. (get_mail_info_reply): Same. (get_mail_info_destroy): Free the URI. (get_mail_info): Take a URI and return the message id so that it can be cancelled if necessary. (mail_folder_cache_remove_folder): Disconnect from signals and events before removing. (mail_folder_cache_note_folder): Use a GQuark instead of the mail_folder_info * as the user_data. (mail_folder_cache_note_fb): Same. (mail_folder_cache_note_folderinfo): Little formatting change. svn path=/trunk/; revision=12532
