Subject DO NOT REPLY [Bug 51497] New: Use canonical IPv6 text representation in logs

             Bug #: 51497
           Summary: Use canonical IPv6 text representation in logs
           Product: Tomcat 7
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Catalina
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: ognjen.d.blagojevic@gmail.com
    Classification: Unclassified


In AccessLogValve and on other places where IPv6 address is logged or printed,
it would bi good if Tomcat would use canonical IPv6 format as described in RFC
5952 [1] (especially note section "3.2.2. Logging"), e.g:

1. instead of logging 2001:4000:0:5:0:0:0:66, it should log 2001:4000:0:5::66,
2. instead of logging 0:0:0:0:0:0:0:1, it should log ::1.


Class Inet6Address method getHostAddress confirms to RFC recommendations, in
everything except in zero groups handling. It simply prints full form with all
zeroes. In Java API I don't see any method to convert it to canonical form.
