Hi all,
Have just comited the new code on keepalived website. The code focus for
this release is configuration file reload on the fly... The devel focus
here has been to reduce to the max the service interruption during
reloading process using a dynamic differential conf framework for both IPVS
and netlink low-level parts.
The ChangeLog for this release is :
2002-07-31 Alexandre Cassen <acassen@xxxxxxxxxxxx>
* keepalived-0.6.9 released.
* Fixe some code dependence selection during compilation. If
autoconf netlink
probe fails then unset VRRP code.
* Cleanup daemon lib. Added some logging info for the daemon
processing, removed
some repeated code part.
* Added 2 new daemon arguments :
--dont-release-vrrp : Dont remove VRRP VIPs on daemon stop
--dont-release-ipvs : Dont remove IPVS topology on daemon stop
* Review the global scheduling process to clear FD queues on
master thread
destroy.
* Fixed a forking issue in the MISC_CHECK.
* Review IPVS wrapper functions to use allocated IPVS rules
instead of static
referencing pointer.
* Fixed the IPVS wrapper to delete IPVS entries according to their
'alive' state.
* Added IPVS support to alive flag for VS entries.
* Rewrote the previous main.c to support configuration reload on
the fly. Extented
signal handling to register a conf reload_thread on SIGHUP. The
software design
used here is a dynamic differential conf file reloading
framework. This design
offer key decision to add/remove new/old entries to/from
low-level framework:
IPVS topology and netlink IP addresses entries. This design
reduce to the max
the global service interruption since only negative diff entries
are removed.
For VRRP config reload on the fly, if you plan to add/remove
many VIPs consider
VIP declaration into the virtual_ipaddress_excluded since they
are not present
into VRRP adverts.
* Review the keepalived.init script to support restart and reload
arguments.
* Fixed some typo issues.
Any comments welcome,
Best regards,
Alexandre
