This makes two main changes:
- Runs syncPod in a separate Go routine (and enforces only one of those
runs at a time).
- Uses the pod list to determine if a container should be running or
should be killed (used to use the output of syncPod).
Since Docker pulls are synchronized by the Docker daemon we still block
on that, but pods can now be removed and prepared for starting without
blocking on long pulls.
- Fix reslice in Pull() to remove the just returned error
- Fix data races found during the integration testing
- Remove one-liner helper method for better readability
Check for 1 path segment on create/list, 2 on update/delete, and
allow any number of path segments on get (for now).
Also pretty prints the list of actual types that are supported for
create/update, which today corresponds to the list of types that
are supported period.
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)
Also transfer the Kubelet from using ContainerManifest.ID to source specific
identifiers with namespacing. Move goroutine behavior out of kubelet/ and
into integration.go and cmd/kubelet/kubelet.go for better isolation.
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.
The pause image is a 240KB image that simply pauses waiting on a signal.
Use this for the net container which only needs to act as a placeholder.
Current net image is ~2.5MB. From my tests, this reduces startup time
for the net container from ~14s to ~6s.
The tests for Docker image name parsing are repetitive and do not
cover enough test cases.
Refactor the tests to use table testing and add additional test cases.
This patch completes a TODO item for the kubecfg package test suite by
removing the expectNoError helper function, which does not reduce enough
typing to justify its usage.
