It looks like the compress plugin assumes that a transform continuation will get triggered when the input VConn closes:
https://github.com/apache/trafficserver/blob/128507ae5a69ab0cbaa6d9707cfe2ad1d95cbed8/plugins/compress/compress.cc#L589 Is this correct? If not, the continuation as well as the allocated "Data" structure will get leaked it seems. If the final trigger doesn't happen in all error cases, then that seems like leaks would happen in those cases.
