@jyemin I've ported the cursor changes to master. However, I'm struggling with the Loadbalancer tests - seems lots are failing. Any ideas on these or how I can test them locally? |
|
I no longer remember how to start up a load balancer locally. You might need to look at how it's done in Evergreen and emulate it. Happy to look at the failures on Evergreen if you point me to them. |

@jyemin See: https://spruce.mongodb.com/version/654a27dd0305b9e381425fdf/tasks?sorts=STATUS%3AASC%3BBASE_STATUS%3ADESC I got haproxy working but the driver throws an error saying the server does not support it. |

Did you find https://github.com/mongodb-labs/drivers-evergreen-tools/blob/master/.evergreen/orchestration/configs/sharded_clusters/basic-load-balancer.json? That will show how to configure mongos to support LB mode. |

CommandBatchCursorSpecification is a unit test. Do we want CommandBatchCursorFunctionalTest instead?

What problem did this address? I can't think of a command that wouldn't have an lsid on it.

com.mongodb.reactivestreams.client.SessionsProseTest.shouldIgnoreImplicitSessionIfConnectionDoesNotSupportSessions failed on 4.2, 5.0, 6.0 due to this erroring.

That seems impossible, since this code change only effects the shouldCreateServerSessionOnlyAfterConnectionCheckout test in which it is contained. I think something else must be happening that caused shouldIgnoreImplicitSessionIfConnectionDoesNotSupportSessions test to fail.

However, looks like there was also an exception opening socket. Which maybe the root cause.
This reverts commit 287a25e.
