Subject: MEDIUM: h2: Destroy a connection with no stream if it has no owner.
X-Git-Tag: v1.9-dev9~99
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=93c88525727f8234eefaeee73ecb71ddb40d7f5c;p=thirdparty%2Fhaproxy.git

MEDIUM: h2: Destroy a connection with no stream if it has no owner.

In h2_detach(), if the connection has no stream left, and no associated
owner, then destroy it, as nobody else will be able to.
