Begin systemizing files in pkg/registry
 2014-08-01 10:57:31 -04:00
Yuki Yugui Sonoda 331fd0d986 Extract "pkg/version".PrintAndExitIfRequested() to its own package 
because it causes a runtime panic if a binary which has its own implementation
of "-version" flag tries to reuse a package library which indirectly depend on
"pkg/version".

e.g. If such an user-defined binary tires to link "pkg/api" or "pkg/client",
the binary fails with a runtime panic "flag redefined: version".

Daniel Smith 7dbb6f02fe Begin systemizing files in pkg/registry 
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.

Daniel Smith 928092e79e Etcd watcher verification 
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/.

Filipe Brandenburger de405ac126 Improve generation of version information from the git tree 
Detect whether the tree is dirty and append a "-dirty" indication to the
git commit (common practice with other repos, e.g. kernel, docker.)

Properly handle the case where a git tree is not found (e.g. building
from archive.)

In the sed expression, look for the variable to be updated
(commitFromGit) instead of hardcoding a line number.

Tested:

- Built from a dirty tree:
    $ output/go/bin/kubelet -version
    Kubernetes version 0.1, build 2d784c684c75-dirty

- Built from a clean tree:
    $ output/go/bin/kubelet -version
    Kubernetes version 0.1, build 505f23a31172

- Built from an archive:
    $ hack/build-go.sh
    WARNING: unable to find git commit, falling back to commitFromGit = `(none)`
    $ output/go/bin/kubelet -version
    Kubernetes version 0.1, build (none)

Clayton Coleman 1bdeb058e1 Slightly pause on requests to allow most to finish 
Currently, every write will result in a 202 (etcd adding a few
ms of latency to each request).  This forces clients to go into
a poll loop and pick a reasonable server poll frequency, which
results in 1 + N queries to the server for the single operation
and adds unavoidable latency to each request which affects their
perception of the service.

Add a very slight (25ms by default) delay to wait for requests
to finish.  For clients doing normal writes this reduces the
requests made against the server to 1.  For clients on long requests
this has no effect.  The downside is that http connections are held
on to for a longer period in high write loads.  The decrease in
perceived latency from the kubecfg is significant.

Francisco Souza 2a345ffa9e third_party: update go-dockerclient 
math.MaxInt64 represents 8 exabytes, which is a good limit for memory.
Also, this is the type used by Docker, so it's not possible to get any
value bigger than math.MaxInt64 as memory limit (both ram and swap) on a
Docker container.

Clayton Coleman a49b331794 Cleanly delete service without endpoints key 
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

Currently all commands are being build with extra flags. The extra

interface to support existing behavior. Also clean up two TODO items
by remove using of the expectError and expectNoError functions.

Victor Marmol b131da1cf5 Sync pods asynchronously in the Kubelet. 
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.

Clayton Coleman fbd7bc375f kubecfg doesn't allow updates because of path checks 
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.

 2014-07-21 15:47:39 -07:00
Kelsey Hightower fce90dc761 Improve test coverage for the health package and remove mocks 
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.

Victor Marmol 88317efb42 Add a pause image for the net container. 
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 -etcd_servers flag is used inconsistently by the Kubernetes commands,

etcd servers internally, and declares the -etcd_servers flag consistently
across all commands.

This patch should be 100% backwards compatible with no changes in behavior.

Generally, it'll be good to turn everything possible into a push instead
of a poll.
