DO NOT REPLY [Bug 52765] New: ZeroConf does not work

https://issues.apache.org/bugzilla/show_bug.cgi?id=52765

             Bug #: 52765
           Summary: ZeroConf does not work
           Product: Log4j
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: P2
         Component: chainsaw
        AssignedTo: log4j-dev <at> logging.apache.org
        ReportedBy: charles.c.strahan <at> gmail.com
    Classification: Unclassified

There are a couple aspects of this problem for me to address, so here we go.
This report is based on the latest trunk of Chainsaw as of earlier today
(should be revision 1178454), on Ubuntu 11.04.

First of all, the old 2006 binary (found here:
http://logging.apache.org/chainsaw/download.html) is capable of detecting
appenders registered with a type of _log4j._tcp.local. This is no longer so in
the latest revision (although it doesn't really hold me back, personally). I
think (per this ticket:
https://issues.apache.org/bugzilla/show_bug.cgi?id=48907) that
_log4j._tcp.local. was supposed to be supported for backwards compatibility
with the ZeroConfSocketHubAppender.

Secondly, I don't think that the ZONEs are formatted correctly for the other

All of the network appenders and receiver now can advertise via Multicast DNS
(which isn't as restrictive when it comes to advertised names as Bounjour) via
a setting in the configuration, so the ZeroConf sockethub appender is no longer
necessary.

I don't mind making the change to be consistent with Bounjour naming
requirements - it isn't technically required -advertising and discovery works
fine with appenders and Chainsaw - but if others have tools which use Bonjour,
I don't mind adding the protocol into the names.

I think I'll just make the multicast dns names configurable (with a reasonable
default).

Hey Scott,

I see - so it isn't that Chainsaw has any problems, it's just that my Ruby
library implements Bonjour as opposed to mDNS, which means I have to specify a
protocol (TCP or UDP)... and Chainsaw isn't expecting that.

Perhaps Chainsaw could support both the less restrictive names _and_ the the
names + protocol, if that wouldn't be impractical and/or a pain in the ass.

If you're curious, I thought it would be nice to have Chainsaw to view my Rails
logs (I already implemented the appropriate XML formatting in Log4r a while
back). In fact, I thought it would be cool to be able to share a snippet of
code with some of my buddies that would handle both the broadcasting of log
messages _and_ the mDNS/Bondjour registration, so they could leverage the
awesomeness that is Chainsaw without having to bother with manually configuring
both ends.

My apologies for taking so long to reply - I just moved 1000 miles from Dallas,
TX to Washington, DC. Thanks for your help!

-Charles

I think it'll be fine to just use bonjour style names.  I'm not sure supporting
configurable names would be useful - if someone requests it I'll add it in the
future.  This will require an update to log4j itself partially (at least the
core socket appenders) as well as Chainsaw.  I'll see if I can get a commit in
sometime this week..

By the way, if you feel like trying out the latest developer snapshot of
Chainsaw is available at http://people.apache.org/~sdeboy - there are a ton of
new features.

(feedback always welcome)

Scott
