[sieve] ABNF error in ManageSieve

2010-11-17 11:58:23
I got the following error report on RFC 5804:

    QUOTED-CHAR           = SAFE-UTF8-CHAR / "\" QUOTED-SPECIALS

    QUOTED-SPECIALS       = DQUOTE / "\"

    SAFE-UTF8-CHAR        = SAFE-CHAR / UTF8-2 / UTF8-3 / UTF8-4
                            ;; <UTF8-2>, <UTF8-3>, and <UTF8-4>
                            ;; are defined in [UTF-8].


    quoted                = DQUOTE *1024QUOTED-CHAR DQUOTE
                            ;; limited to 1024 octets between the <">s


The comment for quoted is not what the syntax rule for quoted does.  The
syntax rule allows as many as 4096 octets, as QUOTED-CHAR is 1-4 octets.

I think that the intent is to limit the overall number of octets, and not
the number of characters.  Otherwise it doesn't make sense at all.

I think the report is correct. The restriction came from ACAP and RFC 2244 says that a quoted string is limited to 1024 octets.

Comments?

Best Regards,
Alexey
