> Dispatch reestablishes connection inspite of deleting the connector
> -------------------------------------------------------------------

> Key: DISPATCH-887
> URL: https://issues.apache.org/jira/browse/DISPATCH-887
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Container
> Affects Versions: 1.0.0
> Reporter: Ganesh Murthy
> Assignee: Ganesh Murthy
> Fix For: 1.1.0
>
>
> There is a race condition happening when a connector is deleted.
> On connector delete, the following function is called
> {code}
> void qd_connection_manager_delete_connector(qd_dispatch_t *qd, void *impl)
> {
> qd_connector_t *ct = (qd_connector_t*) impl;
> if (ct) {
> sys_mutex_lock(ct->lock);
> if (ct->ctx && ct->ctx->pn_conn) {
> qd_connection_invoke_deferred(ct->ctx, deferred_close,
> ct->ctx->pn_conn);
> }
> sys_mutex_unlock(ct->lock);
> DEQ_REMOVE(qd->connection_manager->connectors, ct);
> qd_connector_decref(ct);
> }
> }
> {code}
> The deferred_close() is invoked before qd_connector_decref() is invoked hence
> the connection's connector is still in place and the connector is
> re-established.
