Subject: BUG/MINOR: haload: fix rate limit bypass during stream errors
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=1654e42084cbbb26bffb304fc9bf684e25d5321b;p=thirdparty%2Fhaproxy.git

BUG/MINOR: haload: fix rate limit bypass during stream errors

In hld_strm_task(), stream errors triggered an unconditional task_wakeup()
on the user task. This bypassed arg_rate and caused haload to send connection
retries as fast as possible instead of respecting the configured request rate.

Call hld_usr_schedule() when arg_rate is set to guarantee that
rate pacing is preserved even when streams fail.
