[gmime-devel] Using gmime to Remove Attachments

[Bill Hager <whager gmail com>]

Hello everyone.

I'm trying to write a short program that removes the attachments from an e-mail message(read from stdin) and prints the message(to stdout).  Below is what I have so far.  Unfortunately, it doesn't always remove all the attachments.  I've traced the problem down to something having to do with g_mime_multipart_remove.  I've verified that is_attachment is true for all the attachments in my test cases.  When I put in some additional fprintf's for debugging it looks like remove_each isn't even looking at all the doesn't look at all the mime parts.  However, if I comment out the g_mime_multipart_remove, it looks like remove_attach does get run on all the mime parts.  Does anyone know why it doesn't always remove all of the attachments? Thanks!

I'm using atrpms build of 2.4.7 on CentOS5.5: gmime-2.4.7-1.99.el5.

int is_attachment(GMimeObject *part) {

  if (g_mime_object_get_content_disposition_parameter(part, "filename") ||

      g_mime_object_get_content_type_parameter(part, "name"))

    return 1;

  else

    return 0;

}

void remove_each(GMimeObject *parent, GMimeObject *part, gpointer data) {

  

    if (is_attachment(part) && GMIME_IS_MULTIPART(parent))

      // g_object_unref(part);

      g_mime_multipart_remove((GMimeMultipart*)parent, part);

  else if (GMIME_IS_MESSAGE_PART(part))

    g_mime_message_foreach(g_mime_message_part_get_message((GMimeMessagePart*)part),

                           (GMimeObjectForeachFunc)remove_each, NULL);

}

int main(int argc, char **argv) {

  GMimeStream *stream;

  GMimeParser *parse;

  GMimeMessage *message;

  

  g_mime_init(0);

  

  stream = g_mime_stream_file_new (stdin);

  parse = g_mime_parser_new_with_stream(stream);

  message = g_mime_parser_construct_message(parse);

  

  g_mime_message_foreach(message, (GMimeObjectForeachFunc)remove_each, NULL);

  

  printf(g_mime_object_to_string((GMimeObject*)message));

  

  g_object_unref(message);

  g_object_unref(parse);

  g_object_unref (stream);

  return 0;
