Add a vet target in order to catch suspicious constructs reported by go vet. Vet has successfully detected problems in the past, for example, see c9333b1b9b472feb5cad80e2c8276d41b64bde88 Some vet flags are noisy. In particular, the following flags reports a large amount of generally unharmful constructs: ``` -assign: check for useless assignments -composites: check that composite literals used field-keyed elements -shadow: check for shadowed variables -shadowstrict: whether to be strict about shadowing -unreachable: check for unreachable code ``` In order to skip running the flags mentioned above, vet is invoked on a directory basis with `go tool vet .` since package- level type-checking with `go vet` doesn't accept flags. Hence, each file is vetted in isolation, which is weaker than package-level type-checking. But nevertheless, it might catch suspicious constructs that pose a real issue. The vet target runs the following flags on the entire repo: ``` -asmdecl: check assembly against Go declarations -atomic: check for common mistaken usages of the sync/atomic package -bool: check for mistakes involving boolean operators -buildtags: check that +build tags are valid -copylocks: check that locks are not passed by value -methods: check that canonically named methods are canonically defined -nilfunc: check for comparisons between functions and nil -printf: check printf-like invocations -rangeloops: check that range loop variables are used correctly -shift: check for useless shifts -structtags: check that struct field tags have canonical format and apply to exported fields as needed -unsafeptr: check for misuse of unsafe.Pointer ``` Now and then, it might make sense to check the output of the disabled flags manually. For example, `VETARGS=-unreachable make vet` can detect several lines of dead code that can be deleted, etc. |

Consul
- Website: http://www.consul.io
- IRC:
#consul
on Freenode - Mailing list: Google Groups
Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.
Consul provides several key features:
-
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.
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
Consul runs on Linux, Mac OS X, and Windows. It is recommended to run the Consul servers only on Linux, however.
Quick Start
An extensive quick quick start is viewable on the Consul website:

Documentation

Developing Consul
If you wish to work on Consul itself, you'll first need Go installed (version 1.2+ is required). Make sure you have Go properly installed, including setting up your GOPATH.
Next, clone this repository into $GOPATH/src/github.com/hashicorp/consul
and
then just type make
. In a few moments, you'll have a working consul
executable:
$ go get -u ./...
$ make
...
$ bin/consul
...
note: make
will also place a copy of the binary in the first part of your $GOPATH
You can run tests by typing make test
.
If you make any changes to the code, run make format
in order to automatically
format the code according to Go standards.
