SDK Installation

API Documentation

Version 2.0.3 (17 March 2020)

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 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.

Fixed Issues

  • 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.

Version 2.0.2 (21 February 2020)

Version 2.0.2 is an off-cycle release for the Go SDK 2.0.0.

New Features and Behavioral Changes

  • 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.

Fixed Issues

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

Version 2.0.1 (19 February 2020)

Version 2.0.1 is a maintenance release for the Go SDK 2.0.0.

New Features and Behavioral Changes

  • 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-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.
