A recent change (#16544) moved the
Http::ConnectionPool::Instance*
returned fromThreadLocalCluster::httpConnPool()
behind a new classHttpPoolData
which no longer exposes the pool instance.A temporary workaround was added to Nighthawk's code here to support the this code.
This PR adds two new methods on
HttpPoolData
to allow the removal of said workaround -hasActiveConnections
andaddDrainedCallback
. Both just forward the call to the underlying pool.Risk Level: low, existing functionality isn't affected.
Testing: n/a, only accessor method added.
Docs Changes: n/a.
Release Notes: n/a.
