Hi.
Environment:
- Ubuntu 18.04
- Haproxy 2.0.4 from vbernat repository
I found a strange behaviour of the statistics page if when
alpn h2,http/1.1
is in the "bind" line of the statistics like:
frontend stats-http
mode http
option httplog
bind 10.64.69.192:443 alpn h2,http/1.1 ssl crt
/etc/ssl/private/XXXX-full.pem ssl-min-ver TLSv1.2
How to reproduce:
. select a server in the statistics web page
. choose an action (for example "Set state to DRAIN") in the drop-down
list
. click "Apply"
It seems that the POST never ends and the status is not changed.
If I remove
alpn h2,http/1.1
from the "bind" line, the actions work as usual.
I did not see this behaviour in version 1.9.x.
Is it a known behaviour?
Hi Marco,
I'm able to reproduce the bug. It also affects the H1. It is a matter of timing.
It happens when the headers are received by HAProxy without the body of the POST
request. If all the request is received in one time, there is no problem. But if
the stats applet starts its processing without the body, it is blocked.
I pushed a fix. It was also backported to 2.0. For details, see the commit
bd9e8428 (git.haproxy.org/?p=haproxy.git;a=commit;h=bd9e8428).
Thanks
