Subject: MINOR: filters: Set last_entity when a filter fails on stream_start callback
X-Git-Tag: v3.4-dev6~15
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd9f159210456423c321188d0675101b424e37aa;p=thirdparty%2Fhaproxy.git

MINOR: filters: Set last_entity when a filter fails on stream_start callback

On the stream, the last_entity should reference the last rule or the last
filter evaluated during the stream processing. However, this info was not
saved when a filter failed on strem_start callback function. It is now
fixed.

This patch could be backported as far as 3.1.
