Subject: [MEDIUM] stream_interface: make use of buffer_cut_tail() to report errors
X-Git-Tag: v1.4-dev3~21
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=cb359e3f3cf6d3334d2d07613a374c8d0cd470ae;p=thirdparty%2Fhaproxy.git

[MEDIUM] stream_interface: make use of buffer_cut_tail() to report errors

The stream_int_return() function used to call buffer_erase() on the response
buffer, which completely wipes it without taking care about whatever could
have been there. Now we more carefully strip only data not scheduled to be
sent.
