Betreff: [ANNOUNCE] haproxy-1.8.3


Hi,

HAProxy 1.8.3 was released on 2017/12/30. It added 9 new commits
after version 1.8.2.

The docker images are now updated to 1.8.3

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.

Hi Willy, is there something like this on 1.7.x? This would be useful on eg 
websockets.
