Hi all,
So with the completed agent-check updates and the last batch of merged
fixes, I think we're ready. I'm emitting dev26 so that everyone can test
and report any unexpected annoyance and regressions before we issue -final,
and in an attempt to avoid 1.5.1 the same day as 1.5.0.
The changes in this version are quite small. Conrad Hoffmann fixed a
possible CPU loop when using the systemd wrapper with multiple processes
when reloading. Sasha Pachev fixed a possible buffer overflow when using
regex which add more than the reserved space to the request or response
(very unlikely so low risk but definitely a bug). Thierry Fournier ensured
that the "str" match is used by default for ACLs built from string samples.
Olivier Burgard added time-frame filtering to halog. Dirkjan Bussink fixed
some minor memory leaks on the error path. Cyril Bonté cleaned up some
minor issues on the stats page. And I updated the agent-check to support
multiple actions in response, and added a few stats for SSL key generations
and SSL cache lookups/misses.
Concerning the agent check updates, the agent can now act on these 3
dimensions :
- weight (eg: based on CPU load)
- service operational status up/down (complementary health checks)
- service administrative status (ready/drain/maint)
Now it's possible to easily write an agent which only acts on these
individual statuses without acting on the other ones if needed. Also
all statuses can be forced on the CLI and stats page, and health/agent
checks can be stopped.
I think that by -final we'll include Rémi's work on making the dhparam size
configurable, and Dmitry's proposal to improve the retry/redispatch behaviour
to speed up the switching to another server whenever possible.
Let's say that without any remaining issue to work on during the upcoming
two weeks, we'll release.
Feedback welcome as usual,
Willy
