Description
When ending a session (i.e., an instance of transport::Session), we should ensure it awaits completion of any inflight operations on the networking baton, and then safely removes itself from the baton. Currently, this is not the case:
bool TransportLayerASIO::BatonASIO::cancelSession(Session& session) noexcept override { |
const auto id = session.id(); |
stdx::unique_lock lk(_mutex);
|
if (_sessions.find(id) == _sessions.end()) { |
return false; |
}
|
|
|
_safeExecute(std::move(lk), [ id, this ](stdx::unique_lock<Mutex> lk) noexcept { |
auto iter = _sessions.find(id);
|
if (iter == _sessions.end()) { |
return; |
}
|
auto session = std::exchange(iter->second, {});
|
_sessions.erase(iter);
|
lk.unlock();
|
|
|
session.promise.setError(kCanceled);
|
});
|
return true; |
}
|
Since the baton uses the reactor thread to poll on the sessions, we should ensure the baton is not running anything on behalf of the session before removing it.
