Assertion failure in stream_not_found() after failed getmore operation

XMLWordPrintableJSON

    • Type: Icon: Bug Bug
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • 1.5.0, 1.5.1
    • Affects Version/s: 1.5.0
    • Component/s: libmongoc
    • None

      PHPC has two tests for throwing an exception on a failed getmore. These tests spin up their own server with mongo-orchestration and configure the failReceivedGetmore fail point.

      After upgrading from 1.5.0-rc3 to 1.5.0-rc4, both of these tests trigger an assert failure in libmongoc:

      phpc/src/libmongoc/src/mongoc/mongoc-cluster.c:1470 stream_not_found(): precondition failed: error
Aborted (core dumped)

Termsig=6

      Based on the libmongoc trace log, this assert failure happens when the mongoc_client_t is destroyed during process shutdown. Our trace logs end with:

      OK: Got MongoDB\Driver\Exception\ConnectionException
