+
+ * camel-data-wrapper.c: remove get/set_output_stream operations.
+ They're redundant with write_to_stream, and CamelMimePart and
+ CamelMimeMessage only implement the latter, meaning that trying to
+ get_output_stream on a CamelMimeMessage that was built from pieces
+ rather than being parsed from a stream doesn't work. Anything that
+ uses get_output_stream can be rewritten to use write_to_stream, so
+ we'll standardize on that.
+ (camel_data_wrapper_new): remove this: CamelDataWrapper is
+ supposed to be an abstract class.
+ (write_to_stream): remove default implementation. (Moved to
+ CamelSimpleDataWrapper)
+
+ * camel-simple-data-wrapper.c: resurrect, although it's not really
+ the same thing it was before. A simple data wrapper, which is
+ backed by a CamelStream.
+
+ * camel-mime-part-utils.c
+ (simple_data_wrapper_construct_from_parser): Use
+ construct_from_stream rather than set_output_stream.
+ (camel_mime_part_construct_content_from_parser): Change
+ camel_data_wrapper_new to camel_simple_data_wrapper_new.
+
+ * camel-mime-part.c (camel_mime_part_set_content): Change
+ camel_data_wrapper_new to camel_simple_data_wrapper_new.
