Asim Aslam 3e885308a0 lint: clear the golangci-lint backlog and enforce a blocking lint in CI (#2995)
Fixes #2988. Brings 'golangci-lint run ./...' to zero issues (was ~373):

- errcheck: explicitly ignore fire-and-forget calls with '_ =' (and a small
  errcheck.exclude-functions list for response writes — json Encoder.Encode,
  http ResponseWriter.Write, fmt.Fprint*); genuine cases handled.
- unused: remove dead code (unexported decls and dead test helpers) and the
  imports they orphaned.
- staticcheck: ST1005 error strings, ST1016 receiver names, S1000/S1017/S1019/
  S1023 simplifications, SA4004/SA4006/SA4010 dead code, SA1021 net.IP.Equal,
  SA6002 (store *[]byte in sync.Pool).
- govet: fix a context leak (lostcancel) in internal/util/mdns and move
  t.Fatal/Fatalf out of goroutines (testinggoroutine) in tests.
- ineffassign, unconvert: mechanical fixes.

CI: the Lint workflow now runs a blocking full-tree 'golangci-lint run' on
pushes and PRs (dropped only-new-issues now that the tree is clean).

Verified: go build, go vet, test compilation, and unit tests for the
behaviourally-touched packages all pass.

cli Source

The cli source reads config from parsed flags via a cli.Context.

Format

We expect the use of the urfave/cli package. Upper case flags will be lower cased. Dashes will be used as delimiters for nesting.

Example

micro.Flags(
    cli.StringFlag{
        Name: "database-address",
        Value: "127.0.0.1",
        Usage: "the db address",
    },
    cli.IntFlag{
        Name: "database-port",
        Value: 3306,
        Usage: "the db port",
    },
)

Becomes

{
  "database": {
    "address": "127.0.0.1",
    "port": 3306
  }
}

New and Load Source

Because a cli.Context is needed to retrieve the flags and their values, it is recommended to build your source from within a cli.Action.


func main() {
    // New Service
    service := micro.NewService(
        micro.Name("example"),
        micro.Flags(
            cli.StringFlag{
                Name: "database-address",
                Value: "127.0.0.1",
                Usage: "the db address",
            },
        ),
    )

    var clisrc source.Source

    service.Init(
        micro.Action(func(c *cli.Context) {
            clisrc = cli.NewSource(
                cli.Context(c),
	    )
            // Alternatively, just setup your config right here
        }),
    )

    // ... Load and use that source ...
    conf := config.NewConfig()
    conf.Load(clisrc)
}
