Subject: BUG/MINOR: hpack: fix debugging output of pseudo header names
X-Git-Tag: v1.9-dev1~628
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9e28f459b4d003072d84fce57811b26ff8245f54;p=thirdparty%2Fhaproxy.git

BUG/MINOR: hpack: fix debugging output of pseudo header names

When a pseudo header is used, name.ptr is NULL and we must replace it
with hpack_idx_to_name(). This only affects code built with DEBUG_HPACK.

To be backported to 1.8.
