Hi,
HAProxy 2.3-dev1 was released on 2020/07/17. It added 60 new commits
after version 2.3-dev0.
A few bugs were addressed, as usual, not as scary as they may look like,
to be honest, since it seems unlikely most people will meet them. One of
them may cause a crash that Tim recently met, but we're unsure about the
conditions needed to trigger it, so let's not rush a 2.2 release yet!
For the main visible changes, I can cite:
- new configurable TCP keep-alive interval/probes/count (MIZUTA Takeshi)
- more deinit cleanups to make valgrind happier (Tim Düsterhus)
- "strict-limits" now defaults to "on" so that you'll now get a startup
error if you configure too large a maxconn for your system's limits
instead of experiencing the error once at full load (William Dauchy)
- syslog load balancing (Emeric Brun) : there is now a new "log-forward"
section which listens to UDP syslog and rebalances it to other log
servers, possibly performing a format translation on the fly. This
can both duplicate and load-balance (thanks to the sampling feature),
allowing to, for example, forward over TCP and stderr what's received
over UDP. Please have a look at the example in the doc, it's self
explanatory. This opens the door to future improvements such as
receiving over TCP as well, and/or routing on certain fields and/or
masking/rewriting certain fields (e.g. user names, passwords or credit
card numbers).
And the rest is mostly internal stuff.
We'll try to emit more frequent -dev releases from now on, typically
every 2 weeks, as the end of the 2.2 cycle showed that it improves accuracy
in bug reports, brings less risks to users, and shortens the time needed to
write the announcement :-)
