Make ListWatch work with a ListFunc and WatchFunc
 2015-02-17 14:48:11 -05:00
Clayton Coleman 3e2e4714a2 Always set ?namespace in query if specified 
Revise our code to only call Request.Namespace() if a namespace
*should* be present.  For root scoped resources, namespace should
be ignored.  For namespaced resources, it is an error to have
Namespace=="".

Clayton Coleman 3ca23163ae Add a GetByKey method to Store 
Without the ability to retrieve underlying items by key (instead of
the object passed to KeyFunc) it is impossible to build wrappers
around cache.Store that want to make decisions about keys, because
they would need to reconstruct the object passed to Get.

This allows retrieval by key, and makes sure Get(obj) uses it.

Dan Mace 5ee943d683 Support namespacing in cache.Store implementations 
Support namespacing in cache.Store by framing the interface functions

Move Listers to pkg/client/cache.
 2015-01-07 15:56:14 -08:00
Eric Tune ed74197fde Move Listers to pkg/client/cache. 
I would like to use these in kubelet and kube-proxy.
This is the minimal change to get them moved.
I will follow up with changes to make interfaces consistent
and add Listers for other resources.
 2015-01-07 15:33:17 -08:00
Eric Tune 7d5ac856c5 Make Reflector helpers reusable. 
Scheduler uses Reflector from pkg/client/cache.
It defines some helper classes.
I'd like to use those helpers with pkg/client/cache
in kube-proxy and kubelet too.

Clayton Coleman b2434de777 When connections are broken on Watch, write fewer errors to logs 
Watch depends on long running connections, which intervening proxies
may break without the control of the remote server. Specific errors
handled are io.EOF, io.EOF wrapped by *url.Error, http connection
reset errors (caused by race conditions in golang http code), and
connection reset by peer (simply tolerated).
 2014-12-18 16:15:51 -05:00
Dan Mace 0ad8342a55 Log ErrUnexpectedEOF from watches as warnings 
Watches are often established via long-running HTTP GET requests which
will inevitably time out during the normal course of operations. When
the watches time out, an io.EOF or an io.ErrUnexpectedEOF will bubble
up to client components such as StreamWatcher and Reflector. Treat EOF
as a clean watch termination. Treat ErrUnexpectedEOF as a less-clean
but non-fatal watch termination and log the event at the warning level.

This greatly reduces the amount of log noise generated during what is
ultimately normal operation, and adds the flexibility for the operator
to make a distinction between the EOF conditions if so desired (by
adjusting the logging level).

Clayton Coleman 64d98cba73 Move typemeta.go to api/meta/meta.go 
Prepares for the meta object to front multiple underlying types
when TypeMeta and ObjectMeta is split in internal and v1beta3, but
combined in v1beta1 and v1beta2

Dan Mace 51ec53e2af Fix line-jumping bug in FIFO implementation 
Keep the FIFO's internal set in sync with the queue during Add/Update
operations to prevent a queue line-jumping scenario (described in a
new unit test).
 2014-10-21 16:37:32 -04:00
Clayton Coleman a5462c0678 Change test cases to verify the client sends the received resourceVersion 2014-10-07 19:00:26 -04:00
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
resource versions.

Clayton Coleman d3e51a0f24 Rename JSONBase -> TypeMeta in preparation for v1beta3 
Will make subsequent refactor much easier
 2014-10-07 11:12:16 -04:00
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
