This expands the Stmt and Expr interfaces to add an Init method. This
is used to pass in Debug and Logf values, but is also used to validate
the AST. This gets rid of standalone use of the "log" package.
This allows golang tests to be marked as root or !root using build tags.
The matching tests are then run as expected using our test runner.
This also disables test caching which is unfriendly to repeated test
running and is an absurd golang default to add.
Lastly this hooks up the testing verbose flag to tests that accept a
debug variable.
These tests aren't enabled on travis yet because of how it installs
golang.
This adds the ability to specify internal, resource specific edges, with
and without notifications. We use the special words: "Notify", "Before",
"Listen", and "Depend". They must have the first character capitalized.
They also support the "elvis" operator.
This is an initial implementation of the mgmt language. It is a
declarative (immutable) functional, reactive, domain specific
programming language. It is intended to be a language that is:
* safe
* powerful
* easy to reason about
With these properties, we hope this language, and the mgmt engine will
allow you to model the real-time systems that you'd like to automate.
This also includes a number of other associated changes. Sorry for the
large size of this patch.
