Mike Foley c4e94efe16 Sticky Session Implementation 
- Added process to cleanup stale session affinity records
- Automatically set cloud provided load balancer for sticky session if the service requires it - Note, this only works on GCE right now.
- Changed sessionAffinityMap a map to pointers instead of structs to improve performance
- Commented out cookie and protocol from sessionAffinityDetail to avoid confusion as it is not yet implemented.

Eric Tune 3f285269cc Rename watch.Mux -> watch.Broadcaster 
A few reasons:
- Mux is already widely used in the codebase to refer to a http handler mux.
- Original meaning of Mux was something which sent a chose one of several inputs to
  and output.  This sends one output to all outputs.  Broadcast captures that idea
  better.
- Aligns with similar class config.Broadcaster (see #2747)

Tim Hockin 0c03f6e784 Enable public IPs even in not createExternal... 
This allows the proxier to portal Public IPs even if the
createExternalLoadBalancer flag is not set.

This also fixes what appears to be a bug in the createExternalLoadBalancer path
wherein multiple PublicIPs would get truncated.

derekwaynecarr 039af4a569 Endpoint.Namespace is not being set when it has no resolved pods 2014-11-24 14:15:22 -05:00
Eric Tune f122fc94bf Move service enviroment vars code. 
GetServiceEnvironmentVariables (originally in  pkg/registry/service/rest.go)
is split into two parts: one that lists services, and one that turns
a ServiceList into environment vars.  This will allow a subsequent PR
to add a call to the latter function with an existing ServiceList.
The former part is moved into pkg/registry/pod/bound_pod_factory.go.
The latter part is put in a new package, pkg/kubelet/envvars/envvars.go.
The new package is under kubelet because the container enviroment is more
associated with kubelet than with registry.
Test code moved too.

Clayton Coleman d5ee171410 Allow clients to determine the difference between create or update on PUT 
PUT allows an object to be created (http 201).  This allows REST code to
indicate an object has been created and clients to react to it.

APIServer now deals with <-chan RESTResult instead of <-chan runtime.Object,
allowing more data to be passed through.

Clayton Coleman 82bcdd3b3b Make ResourceVersion a string internally instead of uint64 
Allows us to define different watch versioning regimes in the future
as well as to encode information with the resource version.

This changes /watch/resources?resourceVersion=3 to start the watch at
4 instead of 3, which means clients can read a resource version and
then send it back to the server. Clients should no longer do math on

Clayton Coleman 4e56dafecc Introduce some default log verbosity control 
Move a lot of common error logging into better buckets:

glog.Errorf() - Always an error
glog.Warningf() - Something unexpected, but probably not an error
glog.V(0) - Generally useful for this to ALWAYS be visible
            to an operator
            * Programmer errors
            * Logging extra info about a panic
            * CLI argument handling
glog.V(1) - A reasonable default log level if you don't want
            verbosity
            * Information about config (listening on X, watching Y)
            * Errors that repeat frequently that relate to conditions
              that can be corrected (pod detected as unhealthy)
glog.V(2) - Useful steady state information about the service
            * Logging HTTP requests and their exit code
            * System state changing (killing pod)
            * Controller state change events (starting pods)
            * Scheduler log messages
glog.V(3) - Extended information about changes
            * More info about system state changes
glog.V(4) - Debug level verbosity (for now)
            * Logging in particularly thorny parts of code where
              you may want to come back later and check it

There's still one more step that could usefully be done, which is to

functions and the part that provides the internal types. That can come
later.

The v1beta1 package is now a good example of what an api plugin should
do to version its types.

Clayton Coleman 231ed95a61 Typo in name 2014-08-13 14:36:23 -04:00
Kelsey Hightower c21a0ca39f Breakup the registry package into separate packages. 
Currently all registry implementations live in a single package,
which makes it bit harder to maintain. The different registry
implementations do not follow the same coding style and naming
conventions, which makes the code harder to read.

Breakup the registry package into smaller packages based on
the registry implementation. Refactor the registry packages
to follow a similar coding style and naming convention.

This patch does not introduce any changes in behavior.

Clayton Coleman c9fc0bcf3d Decouple apiserver from codec implementation 
The apiserver on initialization must be provided with a codec
for encoding and decoding all handled objects including api.Status
and api.ServerOp.  In addition, the RESTStorage Extract() method
has been changed to New(), which returns a pointer object that the
codec must decode into (the internal object).  Switched registry
methods to use pointers for Create/Update instead of values.

Clayton Coleman 4f88b778a6 Evolve the api.Status object with Reason/Details 
Contains breaking API change on api.Status#Details (type change)

Turn Details from string -> StatusDetails - a general
bucket for keyed error behavior.  Define an open enumeration
ReasonType exposed as Reason on the status object to provide
machine readable subcategorization beyond HTTP Status Code. Define
a human readable field Message which is common convention (previously
this was joined into Details).

Precedence order: HTTP Status Code, Reason, Details. apiserver would
impose restraints on the ReasonTypes defined by the main apiobject,
and ensure their use is consistent.

There are four long term scenarios this change supports:

1. Allow a client access to a machine readable field that can be
   easily switched on for improving or translating the generic
   server Message.

2. Return a 404 when a composite operation on multiple resources
   fails with enough data so that a client can distinguish which
   item does not exist.  E.g. resource Parent and resource Child,
   POST /parents/1/children to create a new Child, but /parents/1
   is deleted.  POST returns 404, ReasonTypeNotFound, and
   Details.ID = "1", Details.Kind = "parent"

3. Allow a client to receive validation data that is keyed by
   attribute for building user facing UIs around field submission.
   Validation is usually expressed as map[string][]string, but
   that type is less appropriate for many other uses.

4. Allow specific API errors to return more granular failure status
   for specific operations.  An example might be a minion proxy,
   where the operation that failed may be both proxying OR the
   minion itself.  In this case a reason may be defined "proxy_failed"
   corresponding to 502, where the Details field may be extended
   to contain a nested error object.

At this time only ID and Kind are exposed

We should consider splitting this package into two, to make more clear
the separation between the layers.

Daniel Smith 928092e79e Etcd watcher verification

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/.

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.

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.

2) add support for third_party/update.sh to update just one pkg
3) search-and-replace:
  s/log.Printf/glog.Infof/
  s/log.Print/glog.Info/
  s/log.Fatalf/glog.Fatalf/
  s/log.Fatal/glog.Fatal/
4) convert glog.Info.*, err into glog.Error*

Adds some util interfaces to logging and calls them from each cmd, which
will set the default log output to write to glog.  Pass glog-wrapped
Loggers to etcd for logging.

Log files will go to /tmp - we should probably follow this up with a
default log dir for each cmd.

The glog lib is sort of weak in that it only flushes every 30 seconds, so
we spin up our own flushing goroutine.
