    • Type: Icon: Bug Bug
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • 1.2-beta0, 1.1.5
    • Affects Version/s: 1.1.4
    • Component/s: None
    • None

      *UPDATE*: Fixed in 1.1.5, still reproducible in 1.2.0. Uncomment the "/TLS/handshake_stall" test and fix in 1.2.0-dev branch.

      The default stream initiator in mongoc_client.c makes a blocking call to mongoc_stream_tls_do_handshake(). This can cause the driver to full hang until some kind of network error is returned.

      We should pull connecttimeoutms or sockettimeoutms out of the uri and use that in lieu of permanent blocking.
