Move the subscription context to Next. context.Context should generally never be stored in a struct because it makes that struct only valid while the context is valid. This is rarely obvious from the caller. Adds a forceClosed channel in place of the old context, and uses the new context as a way for the caller to stop the Subscription blocking. Remove some recursion out of bufferImte.Next. The caller is already looping so we can continue in that loop instead of recursing. This ensures currentItem is updated immediately (which probably does not matter in practice), and also removes the chance that we overflow the stack. NextNoBlock and FollowAfter do not need to handle bufferItem.Err, the caller already handles it. Moves filter to a method to simplify Next, and more explicitly separate filtering from looping. Also improve some godoc Only unwrap itemBuffer.Err when necessary

Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh/Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without being aware of Connect at all.
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
