SDK Release Notes

GOCBC-1764: Non-TLS connections are not possible with the couchbase2:// scheme. TLS is now always enabled when the couchbase2:// scheme is used, and the system certificate pool is used by default if no certificate options are specified.

GOCBC-1762: Improved logging for WaitUntilReady when no bootstrap error is found before a config is seen, to make it clearer that there was no error.

GOCBC-1765: Improved error message when the couchbase2:// scheme is used in a connection string with a bucket.

GOCBC-1643: Fixed issue where couchbase2 mode did not wait for operations to complete on close.

GOCBC-1626: Addressed an issue where performing operations after calling cluster.Close (or calling close twice) would lead to a panic. On close the SDK will now cancel all in flight operations and block waiting for them to complete/be cancelled. All operations will now fast fail if called after close.

GOCBC-1582: Fixed issue where math.MaxUint32 was causing an error when used with fmt.Errorf.

GOCBC-1482: Fixed issue where there was inconsistency in whether Couchbase error types were returned as pointers across services, now all Couchbase errors are returned as pointers. Improved the string output for TimeoutError. We expect this to have a minimal impact but may impact some users who are using errors.As or directly type asserting errors.

GOCBC-1575: Improved the interface for BucketSetting HistoryRetentionCollectionDefault field to use a constant value rather than a bool pointer.

GOCBC-1470: Added a V2 Collection management API, accessed via Bucket.CollectionsV2(), which has improved method signatures for CreateCollection, UpdateCollection, and DropCollection.

GOCBC-1459: Added support for history retention settings to bucket and collections managers, at API stability uncommitted.

GOCBC-1461: Updated ExistsSpec response to handle ContentAt better:

GOCBC-1540: Added support for ErrDocumentTooDeep which is only used in couchbase2 mode, equivalent to ErrPathTooDeep.

When an error is translated to a QueryPreparedStatementFailureRetryReason it will invalidate the prepared statement cache entry and attempt to reprepare the statement.

GOCBC-1395: Improved timeout error handling for http based services - if we know that an operation has already timed out then we will now immediately return a timeout error. Retry reason context is now carried throughout the lifetime of an entire prepared statement request.

GOCBC-757: Fixed issue where an array of arrays could cause a failure when using Get with Projections.

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 UpsertUser sent an invalid request if a role was specified with no bucket.

GOCBC-879, GOCBC-890: Performing Cluster level operations (query, search, management APIs) before underlying cluster or bucket connections are ready causes errors to be returned. To mitigate this the err := WaitUntilReady(time.Duration, WaitUntilReadyOptions) operation can be used on either Cluster or Bucket which will either:

GOCBC-843: Updated to the new version of gocbcore. This change includes a key behavioral change of no longer reporting non-configuration related connect time errors.

GOCBC-845: Add support for the WaitForReady operation, support waiting for the KeyValue service to be ready.

GOCBC-844: Updated to the latest version of gocbconnstr.

GOCBC-838: Fixed issue where HTTP endpoints were being used when SSL is enabled.

GOCBC-851: Fixed issue where ServerName was not being set on the tls.Config when SSL was use.

GOCBC-853: Fixed issue where using PasswordAuthenticator with a root CA and SSL would cause a panic.

GOCBC-831: Fixed issue where search consistency options were not being set in the request payload.

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 ContentAt works as expected.

GOCBC-700: Made improvements to errors returned from management operations. They now provide more contextual information.

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

GOCBC-719: SDK now consistently creates tracing spans for all HTTP requests.

GOCBC-728: Added cluster level Ping operation.

GOCBC-807: Updated best effort retry strategy to use an exponential backoff calculator.

GOCBC-820: Removed context.Context from search index manager operations. Note that whilst this is a breaking change it was deemed best to break it and make sure any users who are using it know that they are using unused functionality.

GOCBC-814: Fixed issue where search was looking for incorrect field in the JSON response.

GOCBC-817: Fixed issue where opening a bucket with the same name twice led to incorrect behaviour on both buckets.

GOCBC-805: Updated timeout behavior across the SDK to be consistent. If an operation level timeout is provided then it is used, otherwise the respective global timeout is used.

GOCBC-804: Fixed issue with timeouts not being respected for HTTP requests, leading to them never timing out.

GOCBC-775: Improve error message for when performing cluster level operations with no connections available.

GOCBC-776: Added support for KVDurableTimeout.

GOCBC-786: Improve error messages for the UserManager GetUser function.

GOCBC-701: Fixed issue with enhanced prepared statements not being used.

GOCBC-702: Fixed issue with CA root certificates not being able to be provided.

GOCBC-759: Fixed issue with streaming results for HTTP based services timing out unexpectedly.

GOCBC-772: Fixed issue with many of the management API functions timing out immediately.

GOCBC-773: Fixed issue with queries that do not return rows (e.g. mutations) causing errors.

GOCBC-777: Fixed issue with failing operations causing nil pointers.

GOCBC-783: Fixed issue with Exists returning incorrectly if the document was recently deleted.

GOCBC-784: Fixed issue with Unlock returning a doc not found error instead of cas mismatch.

GOCBC-787: Fixed issue with some (xattr related) subdoc operations sending invalid packets.

GOCBC-789: Fixed issue with search index manager FreezePlan function using an invalid HTTP method.

GOCBC-790: Fixed issue with user manager sometimes parsing user role origins incorrectly.

GOCBC-796: Fixed issue with cccp poller hanging if the get cluster config op timed out.

GOCBC-510: Dropped support for connecting using the http scheme.

GOCBC-534: Added support for retry handling.

GOCBC-652: Added support for circuit breakers.

GOCBC-655: Added support for enhanced timeout errors providing more information about operations which timeout.

GOCBC-656: Added support for threshold logging tracer.

GOCBC-680: Updated how we expose and handle errors.

GOCBC-694: A large number of updates including: How query and analytics results are iterated. Minor renaming of various types. Moving search facets, sorting, and queries to a search subpackage. Removing serializers.

GOCBC-740: Updated expiry options to be time.Duration.

GOCBC-760: Moved authenticator to ClusterOptions.
