The thrift_proxy had some bugs related to oneway messages, both when there is an upstream connection pool failure and when the downstream connection closes before the pool connection completes. Both are fixed with theses changes. In addition, modifies the test harness server to accept multiple simulataneous connections. *Risk Level*: low *Testing*: integration test added *Docs Changes*: n/a *Release Notes*: n/a Signed-off-by: Stephan Zuercher <stephan@turbinelabs.io>

With this line removed, where does the cleanup happen instead?

Because the downstream connection is closed, ConnectionManager::onEvent is invoked, which will destroy any items in the rpcs_ list. What was happening before was that the RPC was being destroyed but not removed from rpcs_.

(Which causes a subsequent nullptr dereference.)

(I'm holding off fixing the merge error until #4067 lands, since its reversion is the source of the conflict.) |
