1. Fix a bug where the peering leader routine would not track all active peerings in the "stored" reconciliation map. This could lead to tearing down streams where the token was generated, since the ConnectedStreams() method used for reconciliation returns all streams and not just the ones initiated by this leader routine. 2. Fix a race where stream contexts were being canceled before termination messages were being processed by a peer. Previously the leader routine would tear down streams by canceling their context right after the termination message was sent. This context cancelation could be propagated to the server side faster than the termination message. Now there is a change where the dialing peer uses CloseSend() to signal when no more messages will be sent. Eventually the server peer will read an EOF after receiving and processing the preceding termination message. Using CloseSend() is actually not enough to address the issue mentioned, since it doesn't wait for the server peer to finish processing messages. Because of this now the dialing peer also reads from the stream until an error signals that there are no more messages. Receiving an EOF from our peer indicates that they processed the termination message and have no additional work to do. Given that the stream is being closed, all the messages received by Recv are discarded. We only check for errors to avoid importing new data. |

Consul
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
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, macOS, FreeBSD, Solaris, and Windows and includes an optional browser based UI. 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.
