* server: add placeholder glue for rate limit handler This commit adds a no-op implementation of the rate-limit handler and adds it to the `consul.Server` struct and setup code. This allows us to start working on the net/rpc and gRPC interceptors and config logic. * Add handler errors * Set the global read and write limits * fixing multilimiter moving packages * Fix typo * Simplify globalLimit usage * add multilimiter and tests * exporting LimitedEntity * Apply suggestions from code review Co-authored-by: John Murret <john.murret@hashicorp.com> * add config update and rename config params * add doc string and split config * Apply suggestions from code review Co-authored-by: Dan Upton <daniel@floppy.co> * use timer to avoid go routine leak and change the interface * add comments to tests * fix failing test * add prefix with config edge, refactor tests * Apply suggestions from code review Co-authored-by: Dan Upton <daniel@floppy.co> * refactor to apply configs for limiters under a prefix * add fuzz tests and fix bugs found. Refactor reconcile loop to have a simpler logic * make KeyType an exported type * split the config and limiter trees to fix race conditions in config update * rename variables * fix race in test and remove dead code * fix reconcile loop to not create a timer on each loop * add extra benchmark tests and fix tests * fix benchmark test to pass value to func * server: add placeholder glue for rate limit handler This commit adds a no-op implementation of the rate-limit handler and adds it to the `consul.Server` struct and setup code. This allows us to start working on the net/rpc and gRPC interceptors and config logic. * Set the global read and write limits * fixing multilimiter moving packages * add server configuration for global rate limiting. * remove agent test * remove added stuff from handler * remove added stuff from multilimiter * removing unnecessary TODOs * Removing TODO comment from handler * adding in defaulting to infinite * add disabled status in there * adding in documentation for disabled mode. * make disabled the default. * Add mock and agent test * addig documentation and missing mock file. * Fixing test TestLoad_IntegrationWithFlags * updating docs based on PR feedback. * Updating Request Limits mode to use int based on PR feedback. * Adding RequestLimits struct so we have a nested struct in ReloadableConfig. * fixing linting references * Update agent/consul/rate/handler.go Co-authored-by: Dan Upton <daniel@floppy.co> * Update agent/consul/config.go Co-authored-by: Dan Upton <daniel@floppy.co> * removing the ignore of the request limits in JSON. addingbuilder logic to convert any read rate or write rate less than 0 to rate.Inf * added conversion function to convert request limits object to handler config. * Updating docs to reflect gRPC and RPC are rate limit and as a result, HTTP requests are as well. * Updating values for TestLoad_FullConfig() so that they were different and discernable. * Updating TestRuntimeConfig_Sanitize * Fixing TestLoad_IntegrationWithFlags test * putting nil check in place * fixing rebase * removing change for missing error checks. will put in another PR * Rebasing after default multilimiter config change * resolving rebase issues * updating reference for incomingRPCLimiter to use interface * updating interface * Updating interfaces * Fixing mock reference Co-authored-by: Daniel Upton <daniel@floppy.co> Co-authored-by: Dhia Ayachi <dhia@hashicorp.com> |

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 - Consul Service Mesh 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 with Transparent Proxy.
-
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.
