+
+ Clean up some exception misusage.
+
+ * providers/imap/camel-imap-command.c (camel_imap_command): Use
+ our own internal exception for sending the string and transfer it
+ to @ex if anything goes wrong.
+ (imap_read_response): Use our own internal exception for reading
+ the untagged responses and blah blah blah.
+
+ * camel-session.c (get_service): Use our own internal exception
+ when constructing the service and transfer it to @ex if anything
+ goes wrong.
+
+ * camel-remote-store.c (remote_recv_line): Instead of having
+ gboolean exception, use our own internal exception and copy
+ it to @ex if anything goes wrong.
+
+ * camel-store.c (store_sync): Create an internal exception
+ because sync_folder() checks it for validity. Transfer it to
+ @ex when done.
+
+ * camel-exception.c (camel_exception_get_description): If @ex is
+ NULL, complain - passing NULL exceptions to Camel is okay, but
+ there should be no circumstances under which they're then
+ examined.
+ (camel_exception_get_id): Same here,
+ (camel_exception_xfer): NULL-protect and warn if transferring from
+ a NULL exception.
+
2001-07-17 Jeffrey Stedfast <fejj@ximian.com>
* camel-store.c (init_trash): Use CAMEL_VTRASH_NAME.
