v1.8.0

1.8.0 (2024-12-19)

Features

• Add ability to provide dynamic query parameters (#44) (efc5d86)

v1.7.1

[1.7.1] - 2022-05-10

Fixed:

• In the SSE server implementation, removed string concatenation logic that caused writing of large messages to be unnecessarily memory-intensive. (Thanks, moshegood!)
• The SSE server implementation did not correctly write a message if the data field was empty: it dropped the field entirely, which would cause clients not to read the message.

1.7.0

[1.7.0] - 2022-01-05

This release includes improvements for SSE spec compliance that do not affect usage in the LaunchDarkly Go SDK, but may be relevant in other use cases.

Added:

• Each event returned by the client now includes the last event ID that was seen on this stream (if any), rather than only the ID (if any) that was in that particular event. This is a requirement of the SSE spec. For backward compatibility, Event.Id() still has the old behavior of returning only the ID for that event; the new behavior is in a new interface method, EventWithLastID.LastEventID(). Every event returned by the client implements both Event and EventWithLastID.

Changed:

• CI tests now use the latest v2 release of https://github.com/launchdarkly/sse-contract-tests.

Fixed:

• The client should discard any id: field that contains a null character, as per the SSE spec.

1.6.2

[1.6.2] - 2020-12-02

Fixed:

• Removed extra newline from "Reconnecting in..." log message.

1.6.1

[1.6.1] - 2020-07-23

Changed:

• Server.Handler() now uses the standard context.Context mechanism to detect when a request has been cancelled, instead of the deprecated http.CloseNotifier.

1.6.0

[1.6.0] - 2020-07-23

Added:

• Server.Unregister method for removing a Repository registration and optionally forcing clients to disconnect.
• Server.PublishWithAcknowledgement method for ensuring that an action does not happen until an event has been dispatched.

Fixed:

• Fixed a race condition in which Server might close a channel while another goroutine is trying to write to it. This would happen if you registered a Repository that replays events, started a handler, then closed the Server while the events were still replaying.
• Improved unit test coverage.

1.5.0

[1.5.0] - 2020-07-15

Added:

• Server.MaxConnTime is an optional setting to make the Server automatically close any stream connection that has stayed open for at least that amount of time. This may be useful in preventing server instances from accumulating too many connections in a load-balanced environment.

1.4.3

[1.4.3] - 2020-07-07

Changed:

• The only changes in this release are to the test dependencies, to avoid bringing in unnecessary transitive dependencies such as go-sdk-common. Some of the test dependencies are now modules that can only be used in Go 1.13+, which means that the test build for this project only runs in Go 1.13+, but it can still be imported by projects that use older Go versions.

1.4.2

[1.4.2] - 2020-06-04

Added:

• Added go.mod so this package can be consumed as a module. This does not affect code that is currently consuming it via go get, dep, or govendor.

1.4.1

[1.4.1] - 2020-03-27

Fixed:

• An error in the backoff logic added in v1.4.0 could cause a panic after many successive retries, due to the exponential backoff value exceeding math.MaxInt64 resulting in a negative number being passed to random.Int63n.
