From 1c70e0090563eb9acfbcd59dcecbc833154d3747 Mon Sep 17 00:00:00 2001 From: NotZed Date: Sat, 19 Feb 2000 04:12:40 +0000 Subject: Added exception to call, and fixed caller. 2000-02-18 NotZed * providers/mbox/camel-mbox-search.h (camel_mbox_folder_search_by_expression): Added exception to call, and fixed caller. * providers/mbox/camel-mbox-search.c (camel_mbox_folder_search_by_expression): Major changes, to use the sexp evaluator from filter/filter-sexp.c to implement the searching. (func_body_contains): Changed to support multiple strings in 1 command (results or'd together) * url-util.c (g_url_new): Fixed a typo (colon == 0 isn't right), and made it so full url's are absolute pathed (Dan, this is how it has to work!). Also, always include a path part, even if it is an empty string. 2000-02-16 NotZed * providers/mbox/Makefile.am (libcamelmbox_la_LIBADD): Added libfilter to link line (temporarily?).
