Perform error checking on parsing/execution.
2001-01-23 Not Zed <NotZed@Ximian.com> * camel-filter-search.c (camel_filter_search_match): Perform error checking on parsing/execution. * camel-folder-search.c (camel_folder_search_execute_expression): Perform error handling on search expression. (CamelFolderSearchPrivate): Add a camelexception for error returns. (camel_folder_search_execute_expression): Setup exception pointer. (search_match_all): Quit on error. * providers/imap/camel-imap-summary.c (message_info_load): Removed some debug 'warnings', as they should now be displayed at the toplevel loader, and just made the code match similar code elsewhere. * providers/local/camel-mbox-summary.c (message_info_load): Error handling. (message_info_save): more error handling. * camel-folder-summary.c (message_info_load): Add error handling and sanity checking. (camel_folder_summary_load): Add error checks. (perform_content_info_load): Error + sanity checks. (content_info_load): error + sanity checks. svn path=/trunk/; revision=7739
