This PR switches the Nomad repository from using govendor to Go modules for managing dependencies. Aspects of the Nomad workflow remain pretty much the same. The usual Makefile targets should continue to work as they always did. The API submodule simply defers to the parent Nomad version on the repository, keeping the semantics of API versioning that currently exists.

The dot_import_whitelist option can be used to whitelist certain

imports.
|
||
|
||
Quoting Go Code Review Comments:
|
||
|
||
The import . form can be useful in tests that, due to circular
|
||
dependencies, cannot be made part of the package being tested:
|
||
|
||
package foo_test
|
||
|
||
import (
|
||
"bar/testutil" // also imports "foo"
|
||
. "foo"
|
||
)
|
||
|
||
In this case, the test file cannot be in package foo because it
|
||
uses bar/testutil, which imports foo. So we use the 'import .'
|
||
form to let the file pretend to be part of package foo even though
|
||
it is not. Except for this one case, do not use import . in your
|
||
programs. It makes the programs much harder to read because it is
|
||
unclear whether a name like Quux is a top-level identifier in the
|
||
current package or in an imported package.`,

Error strings should not be capitalized (unless beginning with

proper nouns or acronyms) or end with punctuation, since they are

usually printed following other context. That is, use

fmt.Errorf("something bad") not fmt.Errorf("Something bad"), so

Text: `Quoting Go Code Review Comments:
|
||
|
||
The name of a method's receiver should be a reflection of its
|
||
identity; often a one or two letter abbreviation of its type
|
||
suffices (such as "c" or "cl" for "Client"). Don't use generic
|
||
names such as "me", "this" or "self", identifiers typical of
|
||
object-oriented languages that place more emphasis on methods as
|
||
opposed to functions. The name need not be as descriptive as that
|
||
of a method argument, as its role is obvious and serves no
|
||
documentary purpose. It can be very short as it will appear on
|
||
almost every line of every method of the type; familiarity admits
|
||
brevity. Be consistent, too: if you call the receiver "c" in one

method, don't call it "cl" in another.`,
