etcd_tools.go is not dependent on the specific implementation
(which is provided by pkg/api). All EtcdHelpers are created
with an encoding object which handles Encode/Decode/DecodeInto.
Additional tests added to verify simple atomic flows.
Begins to break up api singleton pattern.
Files that have RESTStorage implementations now end in "storage", and
files that have registries now end in "registry". I removed some
underscores in file names, since it seems to be go style not to have
them. I split minion_registry.go into two files.
We should consider splitting this package into two, to make more clear
the separation between the layers.
To make sure the etcd watcher works, I changed the replication
controller to use watch.Interface. I made apiserver support watches on
controllers, so replicationController can be run only off of the
apiserver. I made sure all the etcd watch testing that used to be in
replicationController is now tested on the new etcd watcher in
pkg/tools/.
If a service is deleted before the etcd key corresponding to its
endpoints has been created, a 500 error is returned (etcd key
not found). Instead, key not found should be ignored silently.
There is a potential race condition with the controller creating
endpoints after the service has been deleted which a cleanup task
should handle in the future.
Closes#684
Return all healthy minions instead of only returning the first several
healthy minions. Without the PR, if the first minion failed with health
check, the machine list is empty, thus GET /api/v1beta1/pods failed
with code 500
The current tests for the health package utilize a fake HTTP client
for testing health checks and only cover a limited set of test cases.
This patch removes the need for mocks by using the httptest package
from the standard library. After removing the fake HTTP client a bug
was found in the health.Check function; it incorrectly assumes that
a http.Response is always non-nil. Fix the issue by moving the defer
that closes the http.Response.Body after error handling.
Related tests in the registry package have be refactored to work with
the changes made to the health.Check function. All methods that implement
the health.HTTPGetInterface interface now return a http.Response with
with a noop http.Response.Body.
This patch does not introduce any changes in behavior.
