    [tracing] Add separate dump provider for sql connection · 3be5b1ec
    ssid authored
    The sql connection memory dump is not thread safe since the connections
    can get deleted while a dump is happening. To make this thread safe,
    this CL introduces a dump provider class owned by the connection. This
    class holds a lock when dumping and deleting the database. Also, to
    workaround thread safe dump provider registration, it uses the
    UnregisterAndDeleteDumpProviderAsync api added in crrev.com/1430073002.
