> Hi,
> HAProxy 2.0-dev4 was released on 2019/05/22. It added 83 new commits
> after version 2.0-dev3.
> This release completes the integration of a few pending features and
> the ongoing necessary cleanups before 2.0.
> A few bugs were addressed in the way to deal with certain connection
> errors, but overall there was nothing dramatic, which indicates we're
> stabilizing (it has been running flawlessly for 1 week now on
> haproxy.org).
> There are a few new features that were already planned. One is the support
> of event ports as an alternate (read "faster") polling method on Solaris,
> by Manu. Another one is the replacement of the slow stream processing by
> a better and more reliable watchdog. It currently only supports Linux
> however, but a FreeBSD port seems reasonably easy to do. It will detect
> inter-thread deadlocks as well as tasks stuck looping in an endless list
> which has been corrupted, and will provoke a panic, dumping all threads
> states, then doing an abort (in hope to get a core). This will allow the
> problem to be immediately detected and even the service to be automatically
> restarted when the service manager supports it. It's also possible to
> consult all threads' states on the CLI using "show threads".
> As previously discussed we have also deprecated the very old req* and rsp*
> directives with warnings suggesting what to use instead. They still work
> but the goal is to kill them in 2.1, so there's no rush to convert your
> configs given that 2.0 is LTS but you will be encouraged to progressively
> adapt your future configs. Likewise "option forceclose" now warns and
> "resolution_pool_size" is an error (it never existed in any release).
> WURFL is now HTX-aware. There are some new developer-friendly commands
> on the CLI when built with -DDEBUG_DEV, they allow to inspect memory
> areas or send signals, which is convenient during development. It should
> have been done earlier!
> Cirrus-CI is enabled to test builds on FreeBSD. To be honest at this point
> it's still not completely clear to me how to fully use it as their
> interface
> is a bit limited but it has the merit of existing. It doesn't build as
> often
> as Travis-CI, and it decided to build the last fix after I tagged this
> release, showing that apparently there's still a build error on FreeBSD,
> that I don't understand for now.
> Lots of code cleanups were done, and some old build options were refreshed
> to match their equivalent makefile option.
> Overall, aside the possible occasional build issues here and there, it's
> expected to be a bit more stable than dev3, which I'm currently already
> satisfied with.
> Let's set on -dev5 around next Wednesday with the final polishing.
> Depending
> on the amount of issues we'll be able to decide on a release date.

I'd like to run sanitizers on vaious combinations, like ZLIB / SLZ, PCRE /
PCRE2 ...
ok, let us do it before Wednesday
