and Horms

+ Version 0.4.8 BETA series
+ Added the nice_failback feature. If the cluster is running when
the primary starts it acts as a secondary. (Luis Claudio)
+ Made the RPM more SuSE-compatible
+ Tidied up logging so it can be to files, to syslog or both (Horms)
+ Tidied up build process (Horms)
+ Updated ldirectord to produce and install a man page and be
compatible with the fwmark options to The Linux Virtual Server (Horms)
+ Added log rotation for ldirectord and heartbeat using logrotate
if it is installed
+ Added Audible Alarm resource by Kirk Lawson
and myself (Horms)
+ Added init script for ldirectord so it can be run independently
of heartbeat (Horms)
+ Added sample config file for ldirectord (Horms)
+ An empty /etc/ha.d/conf/ is now part of the rpm distribution
as this is where ldirectord\'s configuration belongs (Horms)
+ Minor startup script tweaks. Hopefully, we should be able to make core
files should we crash in the future. Thanks to Holger Kiehl for diagnosing
the problem.
+ Changed the default port number to our official IANA port number (694)
+ Fixed the serial locking code so that it unlocks when it shuts down.

+ Version 0.4.7
+ Added the nice_failback feature. If the cluster is running when
the primary starts it acts as a secondary. (Luis Claudio Goncalves)
+ Put in lots of code to make lost packet retransmission happen
+ Stopped trying to use the /proc/ha interface
+ Finished the error recovery in the heartbeat protocol (and got it to work)
+ Added test code for the heartbeat protocol
+ Raised the maximum length of a node name
+ Added Jacob Rief\'s ldirectord resource type
+ Added Stefan Salzer\'s fix for a \'grep\' in IPaddr which
wasn\'t specific enough and would sometimes get IPaddr confused on
IP addresses that prefix-matched.
+ Added Lars Marowsky-Bree\'s suggestion to make the code almost completely
robust with respect to jumping the clock backwards and forwards
+ Added code from Michael Moerz to keep findif from
core dumping if /proc/route can\'t be read.

+ Made start/stop status compatible with SuSE expectations
+ Made resource status detection compatible with SuSE start/stop expectations
+ Fixed a bug relating to serial and ppp-udp authentication (it never worked)
+ added a little more substance to the error recovery for the HB protocol.
+ Fixed a bug for logging from shell scripts
+ Added a little logging for initial resource acquisition

Mitja Sarp ,
and Guenther Thomsen

+ Version 0.4.5
+ Mijta Sarp added a new feature to authenticate heartbeat packets
using a variety of strong authentication techniques
+ Changed resource acquisition and relinquishment to occur in heartbeat,
instead of in the start/stop script. This means you don\'t
*really
*
have to use the start/stop script if you don\'t want to.
+ Added -k option to gracefully shut down current heartbeat instance
+ Added -r option to cause currently running heartbeat to reread config files
+ Added -s option to report on operational status of \"heartbeat\"
+ Sped up resource acquisition on master restart.
+ Added validation of ipresources file at startup time.
+ Added code to allow the IPaddr takeover script to be given the
interface to take over, instead of inferring it. This was requested
by Lars Marowsky-Bree
+ Incorporated patch from Guenther Thomsen to implement locking for
serial ports used for heartbeats
+ Incorporated patch from Guenther Thomsen to clean up logging.
(you can now use syslog and/or file logs)
+ Improved FreeBSD compatibility.
+ Fixed a bug where the FIFO doesn\'t get created correctly.
+ Fixed a couple of uninitialized variables in heartbeat and /proc/ha code
+ Fixed longstanding crash bug related to getting a SIGALRM while in malloc
or free.
+ Implemented new memory management scheme, including memory stats

Fri Sep 17 06:00:00 1999 Alan Robertson ,
Volker Wiegand , and Rudy Pawul
+ Version 0.4.4
+ Fixed a stupid error in handling CIDR addresses in IPaddr.
+ Updated the documentation with the latest from Rudy.

Thu Sep 16 06:00:00 1999 Alan Robertson ,
Volker Wiegand , and Rudy Pawul
+ Version 0.4.3
+ Changed startup scripts to create /dev/watchdog if needed
+ Turned off loading of /proc/ha module by default.
+ Incorporated bug fix from Thomas Hepper to IPaddr for
PPP configurations
+ Put in a fix from Gregor Howey
where Gregor found that I had stripped off the ::resourceid part
of the string in ResourceManager resulting in some bad calls later on.
+ Made it compliant with the FHS (filesystem hierarchy standard)
+ Fixed IP address takeover so we can take over on non-eth0 interface
+ Fixed IP takeover code so we can specify netmasks and broadcast addrs,
or default them at the user\'s option.
+ Added code to report on message buffer usage on SIGUSR[12]
+ Made SIGUSR1 increment debug level, and SIGUSR2 decrement it.
+ Incorporated Rudy\'s latest \"Getting Started\" document
+ Made it largely Debian-compliant. Thanks to Guenther Thomsen, Thomas
Hepper, I�aki Fern�ndez Villanueva and others.
+ Made changes to work better with Red Hat 6.1, and SMP code.
+ Sometimes it seems that the Master Control Process dies :-(

Sun Aug 15 06:00:00 1999 Alan Robertson ,
Volker Wiegand , and Rudy Pawul
+ Version 0.4.2
+ Implemented simple resource groups
+ Implemented application notification for groups starting/stopping
+ Eliminated restriction on floating IPs only being associated with eth0
+ Added a uniform resource model, with IP resources being only one kind.
(Thanks to Lars Marowsky-Bree for a good suggestion)
+ Largely rewrote the IP address takeover code, making it clearer, fit
into the uniform resource model, and removing some restrictions.
+ Preliminary \"Getting Started\" document by Rudy Pawul
+ Improved the /proc/ha code
+ Fixed memory leak associated with serial ports, and problem with return
of control to the \"master\" node.
(Thanks to Holger Kiehl for reporting them, and testing fixes!)

Wed Jul 7 06:00:00 1999 Alan Robertson and
Volker Wiegand
+ Version 0.4.1
+ Fixed major memory leak in 0.4.0 (oops!)
+ Added code to eliminate duplicate packets and log lost ones
+ Tightened up PPP/UDP startup/shutdown code
+ Made PPP/UDP peacefully coexist with \"normal\" udp
+ Made logs more uniform and neater
+ Fixed several other minor bugs
+ Added very preliminary kernel code for monitoring and controlling
heartbeat via /proc/ha. Very cool, but not really done yet.

Thu Jul 1 06:00:00 1999 Alan Robertson
+ Version 0.4.0
+ Changed packet format from single line positional parameter style
to a collection of {name,value} pairs. A vital change for the future.
+ Fixed some bugs with regard to forwarding data around rings
+ We now modify /etc/ppp/ip-up.local, so PPP-udp works out of the box
(at least for Red Hat)

(it\'s pretty good for a first version!)

Thu Jun 10 06:00:00 1999 Alan Robertson

+ Version 0.2.0
+ Make an RPM out of it

- Known Bugs
- Only supports 2-node clusters
- Only supports a single IP interface per node in the cluster

- No documentation
- Not very useful yet :-)
