Set the preface/postface from the parser into the multipart object.
2000-11-04 Not Zed <NotZed@HelixCode.com> * camel-mime-part-utils.c (camel_mime_part_construct_content_from_parser): Set the preface/postface from the parser into the multipart object. * camel-multipart.c (camel_multipart_set_postface): Function to set the postface text on a multipart. (camel_multipart_set_preface): Similarly for preface text. * camel-mime-parser.c (folder_scan_content): If we scan until a boundary, then we do not include the \n that starts the boundary line in the content. (struct _header_scan_stack): Added a ByteArray to store the multipart pre/post-text as we're scanning. (folder_pull_part): Free pre/posttext if they are allocated. (folder_scan_step): Build into the pre/posttext arrays as we encounter data. (camel_mime_parser_preface): REturn the multipart preface text, if there is any scanned. (camel_mime_parser_postface): Likewise for postface text. (byte_array_to_string): helper function for above. * providers/mbox/camel-mbox-folder.c (mbox_append_message): Change the from line to be "\nFrom ..." always, so no need to check/append a \n to messages. (mbox_append_message): Open the output stream with append mode [assuming this is more efficient than seeking to the end] And dont prepend \n on the From line if its the first in the mbox. (mbox_append_message): Pass the offset of the real start of the "From " line when we perform the update (which may != 'seek') * camel-mime-filter-charset.c (complete): Removed the terminating NUL 'fix'. * camel-stream-filter.c (do_read): Added some debug. (do_flush): And here. (do_write): And here too. (do_write): ARGH!!! ARGH! Ok, so the filter stream was writing a different number of bytes than the requester was asking it to write (because of filtering, of course!). So instead of returning the true number of written bytes, we'll return what they asked us to write - unless there is an error in which case we return -1. * camel-mime-utils.c (base64_encode_close): Sigh, forgot to make it unsigned. I think this is actually a gcc bug as (48 >> 2) somehow ended up negative, when it obviously should not, even if the data load was signed. svn path=/trunk/; revision=6388
