WaitUntilReadyat theClusterlevel would always timeout.
Version 2.1.2 (16 June 2020)
Version 2.1.2 is a maintenance release for the Go SDK 2.1.0.
Fixed Issues
-
GOCBC-879, GOCBC-890: Fixed issue causing
Clusterlevel operations to return errors when performed before underlying cluster or bucket connections are ready. These operations (query, search, analytics, views, management APIs) will now behave like key value operations - waiting for connections to be ready before they are sent. TheWaitUntilReadycall can still be used for verifying that connections are ready. -
GOCBC-891: Fixed issue where the
Nameproperty of aRolewas being sent as the incorrect json field name. -
GOCBC-897: Fixed issue where operations with incredible short timeouts (timing out before operation sent) could cause a data race.

IgnoreIfExistsoption was being ignored for query index management. -
GOCBC-906: Fixed issue where enhanced durability could be incorrectly set as unsupported on early operations.
-
GOCBC-914: Fixed issue where operations using named collections could be sent with an incorrect collection ID in queued before the collection is known.
Known issues
-
GOCBC-941: Performing
ClusterlevelWaitUntilReadynever completes within the timeout. This issue was introduced whilst fixing the behaviour for operations at theClusterlevel when theWaitUntilReadycall is not used. The workaround for this is to not use theClusterlevelWaitUntilReadycall,Clusterlevel operations will now be queued until the SDK has connected and setup anyway.
Version 2.1.1 (19 May 2020)
Version 2.1.1 is a maintenance release for the Go SDK 2.1.0.
New Features and Behavioral Changes
-
GOCBC-778: Updated legacy durability polling to use a backoff rather than a fixed interval.
-

-
GOCBC-828: Added
MaxExpiryto theCollectionSpec. -

Fixed Issues
-
GOCBC-691: Fixed issue where operations on unknown collections (when using 6.5 developer preview) are not automatically retried.
-
GOCBC-757: Fixed issue where an array of arrays could cause a failure when using
GetwithProjections. -
GOCBC-882: Fixed issue where an invalid cluster config would trigger a shutdown of the underlying core SDK causing operations to fail.
-
GOCBC-884: Fixed issue where
UpsertUsersent an invalid request if a role was specified with no bucket.
Known issues
-
GOCBC-879, GOCBC-890: Performing
Clusterlevel operations (query, search, management APIs) before underlying cluster or bucket connections are ready causes errors to be returned. To mitigate this theerr := WaitUntilReady(time.Duration, WaitUntilReadyOptions)operation can be used on eitherClusterorBucketwhich will either:-
Return no error if connections are setup and ready for use
-
Return a
TimeoutErrorif connections are not ready within the specified time limit.
-

Version 2.0.3 is a maintenance release for the Go SDK 2.0.0.
New Features and Behavioral Changes
-
GOCBC-662: The server requires that any subdoc xattr ops are at the beginning of the ops list. If the user provides an ops list containing subdoc xattr ops out of order, the SDK will now reorder it for them and then reorder it back again when it gets the result. This ensures that
ContentAtworks as expected. -

GOCBC-716: SDK now returns a
FlushNotEnablederror if bucket flush not enabled. -
