Hi, HAProxy 2.0.4 was released on 2019/08/06. It added 30 new commits after version 2.0.3.
This release mainly addresses a thread deadlock issue in the queue management, a significant number of H2 issues, and the usual lot of htx, stream, lua and check fixes. When working on Patrick Hemmer's bug reported a month ago (thanks Patrick for all your traces by the way) I had a fairly long head scratching, trying to figure how such impossible stuff could be present in the traces, until I started to build a nice collection of fixes for various small bugs which very likely explain a number of remaining issues people have been facing on HTTP/2 namely on gRPC, as well as what Luke noticed with his map server. So the opportunity was too great to produce a new version and wipe all these problems at once from possible candidates for future bug reports. I've spent so much time on this ones that I simply don't remember what the other ones were about, but the changelog will help. I'd suggest that anyone using HTTP/2 or having had a bad experience with it (particularly with spurious resets or with stalled transfers) gives 2.0.4 a try. I'm also interested in feedback on the smtp/mysql/pgsql checks. It was reported in issue 187 that we recently started to close checks a bit too aggressively, which was indeed right. I relaxed this for the protocols where I knew we were supposed to be nice with the server and close first at the expense of accumulating TIME_WAITs. The reporter didn't see any improvement though it was OK for me. Thus if anyone is having issues where a checked server logs errors about aborted connections, please test this version as well. I've already updated the 1.9 branch with all pending fixes but I'm not sure it's worth emitting 1.9.10 yet since most of these are mostly annoying but not serious enough to force everyone to upgrade again. However since 1.8 definitely needs a new one, we might still have to emit one of each branch (as I don't want anyone to face regressions when upgrading from the latest stable of a branch to the latest stable of a more recent branch). Now it's time to let my old worn out brain have some rest...
