Paul Banks 78c1528c48 cache: fix bug where TTLs were ignored leading to leaked memory in client agents (#9978)
* Fix bug in cache where TTLs are effectively ignored

This mostly affects streaming since streaming will immediately return from Fetch calls when the state is Closed on eviction which causes the race condition every time.

However this also affects all other cache types if the fetch call happens to return between the eviction and then next time around the Get loop by any client.

There is a separate bug that allows cache items to be evicted even when there are active clients which is the trigger here.

* Add changelog entry

* Update .changelog/9978.txt

Consul CircleCI Discuss

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.
