Subject: MINOR: mux-h2: add missing glitch count for non-decodable H2 headers
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=52adeef7e154f7fc9401c923517051c3ff6282fd;p=thirdparty%2Fhaproxy.git

MINOR: mux-h2: add missing glitch count for non-decodable H2 headers

One rare error case could produce a protocol error on the stream when
not being able to decode response headers wasn't being accounted as a
glitch, so let's fix it.
