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.
