This class implements preparing internationalized domain names using the rules defined in RFC 3491, section 4 (Conversion operations). We do not perform step 4 since we deal with unicode representations of domain names and do not convert from or to ASCII representations using punycode encoding. When such a conversion is needed, the C{idna} standard library provides the C{ToUnicode()} and C{ToASCII()} functions. Note that C{idna} itself assumes UseSTD3ASCIIRules to be false. The following steps are performed by C{prepare()}: - Split the domain name in labels at the dots (RFC 3490, 3.1) - Apply nameprep proper on each label (RFC 3491) - Enforce the restrictions on ASCII characters in host names by assuming STD3ASCIIRules to be true. (STD 3) - Rejoin the labels using the label separator U+002E (full stop). cCsg|]}t|qSr)chr).0nrrr szNamePrep.r-.0:A[a{cCs\g}tj|}|rt|ddkrd}|d=nd}|D] }|||qd||S)NrOr.rC)rdotssplitlenrDnamepreprE)r"r@rAlabels trailing_dotlabelrrrrBs zNamePrep.preparecCs(|D]}||jvrtdt|qdSrH)r7rIrJrMrrrr>rNzNamePrep.check_prohibitedscCs@t|}|||ddkrtd|ddkrtd|S)Nr-zInvalid leading hyphen-minusrOzInvalid trailing hyphen-minus)rrfr>rI)r"rirrrrfs    zNamePrep.nameprepN) rrrrrranger7rBr>rfrrrrrTs  rT)"&'/:<>@)r5r7)5rK encodingsr itertoolsrr=rzope.interfacerr incrementalrtwisted.python.deprecaterr rrrrr)r/r1r4rT in_table_c11C_11 in_table_c12C_12 in_table_c21C_21 in_table_c22C_22 in_table_c3C_3 in_table_c4C_4 in_table_c5C_5 in_table_c6C_6 in_table_c7C_7 in_table_c8C_8 in_table_c9C_9 in_table_b1B_1 map_table_b2B_2nodeprep resourcepreprfrrrrst        H A
