Make all kubelet config sources ensure that UID and Namespace are defaulted, if
need be.
We can *almost* disable the "if blank" logic for UID, except for tests that
call APIs that do not run through SyncPods. We really ought to be enforcing
invariants better.
There are three values that uniquely identify a pod on a host -
the configuration source (etcd, file, http), the pod name, and the
pod namespace. This change ensures that configuration properly
makes those names unique by changing podFullName to contain both
name (currently ID in v1beta1, Name in v1beta3) and namespace.
The Kubelet does not properly handle information requests for
pods not in the default namespace at this time.
Also rename some to other names that make better reading. There are still a
bunch of "make" functions but they do things like assemble a string from parts
or build an array of things. It seemed that "make" there seemed fine. "New"
is for "constructors".
Ensure that pods coming from the unit test configuration validate,
and that proper names are generated.
Lowercases source filenames, strips all but a-z0-9, and tests
for consistent results.
Currently all commands are being build with extra flags. The extra
flags appear because of a direct import of the testing package from
the fake_etcd_client.go source file.
Remove the direct import of the testing package. Add a tools.T
interface to support existing behavior. Also clean up two TODO items
by remove using of the expectError and expectNoError functions.
Fixes#579
The next index to watch should always be current+1 if we got a
response from etcd, but otherwise it should always be current.
Moved the increment into fetchNextState which returns the next
index to watch for (or the same if an error occurs)
