Invalid text declaration

[nrolans]

I'm trying to generate files with mib2go (v0.2.0). I think some types are dropped by the clause below, everything is fine if I comment it out.

gosmi/smi/internal/module.go

Lines 452 to 455 in 140d533

	if parentType.Decl == types.DeclTextualConvention {
	// This is invalid
	break
	}

Here is an example of a field that is not found when loading the RMON2-MIB. LastCreateTime has TimeStamp as a parent type with a textual convention.

$ ./mib2go generate -d mibs -M /<redacted>/snmp-mibs RMON2-MIB
2020/09/11 11:23:33 [I] Setting path /<redacted>/snmp-mibs
2020/09/11 11:23:33 [E] Module RMON2-MIB: Type not found for node etherStatsCreateTime

RMON2-MIB (LAST-UPDATED "9605270000Z")

IMPORTS TEXTUAL-CONVENTION, RowStatus, DisplayString, TimeStamp FROM SNMPv2-TC

etherStatsCreateTime OBJECT-TYPE
    SYNTAX     LastCreateTime
    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
        "The value of sysUpTime when this control entry was last
        activated. This can be used by the management station to
        ensure that the table has not been deleted and recreated
        between polls."
    ::= { etherStats2Entry 2 }


LastCreateTime ::= TEXTUAL-CONVENTION
    STATUS current
    DESCRIPTION
        "This TC describes an object that stores the last time its
        entry was created.

        This can be used for polling applications to determine that an
        entry has been deleted and re-created between polls, causing
        an otherwise undetectable discontinuity in the data."
    SYNTAX TimeStamp

SNMPv2-TC

TimeStamp ::= TEXTUAL-CONVENTION
    STATUS       current
    DESCRIPTION
            "The value of the sysUpTime object at which a specific
            occurrence happened.  The specific occurrence must be
            defined in the description of any object defined using this
            type."
    SYNTAX       TimeTicks

I have the same issues with LLDP-MIB (revision 200505060000Z): LLDP-MIB::lldpRemTimeMark -> RMON2-MIB::TimeFilter -> SNMPv2-SMI::TimeTicks.

These are very common MIBs so I'm probably doing something wrong. What am I missing?

Per RFC 2579 Section 3.5 "... the SYNTAX clause of a Textual Convention can not refer to a previously defined Textual Convention." That's why the referenced lines of code are in there. It looks like revision 200605020000Z of RMON2-MIB (RFC 4502) corrected this issue.

Thank you for the very quick response! Problem solved :)
