I am pleased to announce the fifth testing (Alpha 5) release of Corosync
3.0 (codename Camelback) available immediately from our website at
http://build.clusterlabs.org/corosync/releases/ as corosync-2.99.4.
You can also download RPMs for various distributions from CI
https://kronosnet.org/builds/.
This release turns out to be quite bigger than I've expected, so that's
the reason why it's not Beta/RC yet. It also contains quite a lot of
removal of unused/unmaintained code.
List of biggest changes and backwards compatibility breakages with
reasoning and replacement (if needed):
- Removal of CTS - unmaintained for long time and unused by developers,
currently without replacement.
- libtotem is no longer shared library and it's directly compiled into
corosync binary - main idea of having libtotem.so was to allow other
projects usage of libtotem and build custom "corosync" on top of it.
This idea actually never got expected usage and because it was super
big, it was just making corosync development much harder. This doesn't
affect any corosync user. In future totemsrp.c should be made into real
well testable library without network protocol handling, ... but right
now, there is no replacement for libtotem.so.
- Remove usage of all environment variables and tied up corosync arguments:
- -p, -P, -R and -r options - replaced by system.sched_rr,
system.priority and system.move_to_root_cgroup options in the config file.
- env COROSYNC_MAIN_CONFIG_FILE - Replaced by "-c" option. This also
affects uidgid.d location.
- env COROSYNC_TOTEM_AUTHKEY_FILE - Replaced by (already existing)
totem.keyfile config option, which is now documented.
- env COROSYNC_RUN_DIR - Replaced by system.run_dir and documented.
- Usage of libcgroup removal - deprecated in most of new distributions,
replaced by "short" code with even functionality.
- NSS dependency removal - not needed anymore because crypto is now
handled by knet, so no replacement needed. This change affects only
cpgverify where packet format is changed.
- Corosync config file parser updated so it's now more strict and
(finally) displays line with error. Affects only broken config files.
- With new enough LibQB, it's possible to send command to corosync and
it tries reopen its log files. Used by logrotate in favor of old
copytruncate method. Copytruncate still exists and is compiled/installed
by default with old LibQB.
- Timestamps are now enabled by default. With new enough LibQB hires
(including milliseconds) timestamps are used by default.
