DCC version 1.3.114/2.3.114 released

Version 1.3.114 of the DCC source is in
http://www.dcc-servers.net/dcc/source/dcc.tar.Z  and
http://www.rhyolite.com/dcc/source/dcc.tar.Z

Commercial version 2.3.114 of the DCC Reputation code is in the usual place.

I hope to release another version in a week or two with changes to
DCC-server-to-server flooding.   The fix to the high RTT problem
should not wait.


The CHANGES file in
http://www.dcc-servers.net/dcc/dcc-tree/CHANGES and
http://www.rhyolite.com/dcc/dcc-tree/CHANGES and
starts with
    Make `/var/dcc/libexec/dcc-nagios -s server` monitor the number of
        working floods.
    Fix the high RTT bug reported by Petar Bogdanovic and Mike Cappella.
    Speed up dbclean.

/var/dcc/libexec/updatedcc should automagically fetch, build, and
install the commercial or free version, depending on the .updatedcc_pfile
file, unless you have installed a version of Linux with the broken
default `sort` collating sequence since last upgrading.  If so, an
easy way to get the old updatedcc script working is to delete the
entire /var/dcc/build/dcc directory before running updatedcc.

I built it on freebsd 7.2 and it crashes:

#0  0x08054554 in iflod_read ()
#1  0x0804d741 in main ()

I realize this isn't much of a backtrace, I've backed off to 1.1.103 and
will try to build with symbols and get a better traceback.

R's,
John

I see no crashes in the DCC server, dccd, on a 32-bit FreeBSD 7.2
system I built today for the purpose.
However, that program counter was enough of a clue to find a bug
that ought to cause crashes.

I've released version 1.3.115/2.3.115 with what I hope is a fix.

An easy way to build with symbols and line numbers is to use
updatedcc, as in:

   /var/dcc/updatedcc -e DBGFLAGS=-g

Updatedcc can also be used to back off to a previous version, as in:

   /var/dcc/updatedcc -V 1.3.113

However, with the fix in 1.3.115, I hope neither of those are needed now.


thanks,

It's been running less than an hour, but since the .114 crash happened
about every two minutes, that seems to have fixed it.  Thanks!

R's,
John
