/** * call-seq: * parser.execute(req_hash, data, start) -> Integer * * Takes a Hash and a String of data, parses the String of data filling in the Hash * returning an Integer to indicate how much of the data has been read. No matter * what the return value, you should call HttpParser#finished? and HttpParser#error? * to figure out if it's done parsing or there was an error. * * This function now throws an exception when there is a parsing error. This makes * the logic for working with the parser much easier. You can still test for an * error, but now you need to wrap the parser with an exception handling block. * * The third argument allows for parsing a partial request and then continuing * the parsing from that position. It needs all of the original data as well * so you have to append to the data buffer as you read. */ VALUE HttpParser_execute(VALUE self, VALUE req_hash, VALUE data, VALUE start) { http_parser *http = NULL; int from = 0; char *dptr = NULL; long dlen = 0; DATA_GET(self, http_parser, http); from = FIX2INT(start); dptr = RSTRING(data)->ptr; dlen = RSTRING(data)->len; if(from >= dlen) { rb_raise(eHttpParserError, "Requested start is after data buffer end."); } else { http->data = (void *)req_hash; http_parser_execute(http, dptr, dlen, from); VALIDATE_MAX_LENGTH(http_parser_nread(http), HEADER); if(http_parser_has_error(http)) { rb_raise(eHttpParserError, "Invalid HTTP format, parsing fails."); } else { return INT2FIX(http_parser_nread(http)); } } }
