I think there was a rare race where we would make use of the etcd server
before it had fully started up. I only ever saw this occur on travis,
and with this fix hopefully we'll never see it again.
It is worth mentioning that much of my etcd code and the lib Run()
function could use a solid cleaning.
It's up to the end user to decide who is writing and/or overwriting
them.
It could also be useful to reimplement (refactor) some of the existing
World API's to be implemented in terms of these primitives.
This is required if we're going to have out of package resources. In
particular for third party packages, and also for if we decide to split
out each resource into a separate sub package.
This cleans up the API to not have a special case for etcd anymore. In
particular, this also adds the requirement that the GAPI must generate
an event on startup as soon as it is ready to generate a graph.
Since we don't return the actual values and instead only tell about
events (which leaves the `Get` of the value as a second operation) then
we don't have to use a channel with backpressure since all the events
are identical.
This is the initial base of what will hopefully become a powerful API
that machines will use to communicate. It will be the basis of the
stateful data store that can be used for exported resources, fact
exchange, state machine flags, locks, and much more.
This is a monster patch that splits out the yaml and puppet based graph
generation and pushes them behind a common API. In addition alternate
pluggable GAPI's can be easily added! The important side benefit is that
you can now write a custom GAPI for embedding mgmt!
This also includes some slight clean ups that I didn't find it worth
splitting into separate patches.
Felix pointed out that these ID's are unique, but not universally unique
across the cluster, which might be confusing to new programmers. As a
result, rename them all.
This makes this logically more separate! :) As an aside...
I really hate the way golang does dependencies and packages. Yes, some
people insist on nesting their code deep into a $GOPATH, which is fine
if you're a google dev and are forced to work this way, but annoying for
the rest of the world. Your code shouldn't need a git commit to switch
to a a different vcs host! Gah I hate this so much.
