Hi, HAProxy 1.8.3 was released on 2017/12/30. It added 9 new commits after version 1.8.2.
It's essentially focused on fixing the problems reported last week on HTTP/2 and on the master-worker : - fixed the HTTP/2 POST/PUT which would occasionally forward a shutdown to the server resulting in server errors ; - fixed an occasional 400 bad request on HTTP/2 which would happen when large headers displace previous ones within the same request, due to a missing copy of the name (the value was correct). It may have caused some authentication to occasionally be lost (eg: lost cookie header) and of course some requests to be rejected when this resulted in upper case characters in their name. - implemented the graceful shutdown on HTTP/2 connections during a reload so that we can inform the client we're going to close, encouraging the client to switch to a new connection. This avoids connections from lasting forever after reloads on H2. I also noticed that it allows the process to be replaced faster. - open /dev/null on fd 0,1,2 after startup so that we never end up with sockets or pipes on these FDs, which is otherwise problematic in master worker mode. Users of 1.8 must upgrade. Please don't report bugs affecting older 1.8 versions now, so that efforts are focused on fixing new bugs. I'd like to address a special big thanks to Lucas Rolff and Lukas Tribus for their help on the two main HTTP/2 bugs, as the issues were impossible to reproduce outside of the reporter's environment and their help was crucial here. This is hopefully the last release of the year, so I wish you all a happy new year.
