Volker Wiegand
Mitja Sarp
and Guenther Thomsen
+ Version 0.4.7
+ 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
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
core dumping if /proc/route can't be read. - Mon Nov 22 1999 Alan Robertson <alanr@henge.com>,

Volker Wiegand
Mitja Sarp
and Guenther Thomsen
+ Version 0.4.6
+ Fixed timing problem in "heartbeat restart" so it's reliable now
+ 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
+ Added #!/bin/sh to the front of shell scripts
+ Fixed Makefile, so that the build root wasn't compiled into pathnames
+ Turned on CTSRTS, enabling for flow control for serial ports.
+ Fixed a bug which kept it from working in non-English environments - Wed Oct 13 1999 Alan Robertson <alanr@henge.com>,
Volker Wiegand
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 - Thu Sep 16 1999 Alan Robertson <alanr@henge.com>,
Volker Wiegand
+ Version 0.4.4
+ Fixed a stupid error in handling CIDR addresses in IPaddr.
+ Updated the documentation with the latest from Rudy. - Wed Sep 15 1999 Alan Robertson <alanr@henge.com>,
Volker Wiegand
+ 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
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, Iñaki Fernández 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 :-( - Sat Aug 14 1999 Alan Robertson <alanr@henge.com>,
Volker Wiegand
+ 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!) - Tue Jul 6 1999 Alan Robertson <alanr@henge.com> 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. - Wed Jun 30 1999 Alan Robertson <alanr@henge.com>
+ 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)
+ Includes the first version of Volker Wiegand's Hardware Installation Guide
(it's pretty good for a first version!) - Wed Jun 9 1999 Alan Robertson <alanr@henge.com>
+ Version 0.3.2
+ Added UDP/PPP bidirectional serial ring heartbeat
(PPP ensures data integrity on the serial links)
+ fixed a stupid bug which caused shutdown to give unpredictable
results
+ added timestamps to /var/log/ha-log messages
+ fixed a couple of other minor oversights. - Mon May 10 1999 Alan Robertson <alanr@henge.com>
+ Version 0.3.1
+ Make ChangeLog file from RPM specfile
+ Made ipresources only install in the DOC directory as a sample - Sun May 9 1999 Alan Robertson <alanr@henge.com>
+ Version 0.3.0
+ Added UDP broadcast heartbeat (courtesy of Tom Vogt)
+ Significantly restructured code making it easier to add heartbeat media
+ added new directives to config file:
+ udp interface-name
+ udpport port-number
+ baud serial-baud-rate
+ made manual daemon shutdown easier (only need to kill one)
+ moved the sample ha.cf file to the Doc directory - Sat Mar 27 1999 Alan Robertson <alanr@henge.com>
+ Version 0.2.0
+ Make an RPM out of it
+ Integrated IP address takeover gotten from Horms
+ Added support to tickle a watchdog timer whenever our heart beats
+ Integrated enough basic code to allow a 2-node demo to occur
+ Integrated patches from Andrew Hildebrand
to run under IRIX.
- Known Bugs
- Only supports 2-node clusters
- Only supports a single IP interface per node in the cluster
- Doesn't yet include Tom Vogt's ethernet heartbeat code
- No documentation
- Not very useful yet :-)
