Subject: BUG/MEDIUM: h2: Don't try to chunk data when using HTX.
X-Git-Tag: v1.9-dev10~4
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/static/gitweb.js?a=commitdiff_plain;h=50d660c54599db6ef05b267ac1e062d3718b035f;p=haproxy.git

BUG/MEDIUM: h2: Don't try to chunk data when using HTX.

When we're using HTX, we don't have to generate chunk header/trailers, and
that ultimately leads to a crash when we try to access a buffer that
contains just chunk trailers.

This should not be backported.
