Daniel Smith e2b645ec15 Add a generic proxier 
To proxy traffic to anything that implements ResourceLocation.
Currently, this is only services. This is easily extensible to minions
(would supercede existing mechanism) and pods.

Tim Hockin 0f97a73c1b Rename a bunch of "Make" functions to "New" 
Also rename some to other names that make better reading.  There are still a
bunch of "make" functions but they do things like assemble a string from parts
or build an array of things.  It seemed that "make" there seemed fine.  "New"
is for "constructors".

Clayton Coleman bbf3b55e76 Extract RESTHandler and allow API groupings 
Prepare for running multiple API versions on the same HTTP server
by decoupling some of the mechanics of apiserver.  Define a new
APIGroup object which represents a version of the API.
 2014-08-13 10:53:34 -04:00
Clayton Coleman 0083fae453 Provide helpers and tests for common error types 
Unify error handling in apiserver into a single path - RESTStorage
objects must provide appropriate errors individually.  Ensure ALL
errors which can be traced to logical faults with RESTStorage are
returned as api.Status objects.
 2014-08-08 19:44:47 -04:00
Clayton Coleman a74fac7d70 Centralize path magic in apiserver into the New method 
Make OperationHandler and WatchHandler properly encapsulate their
concerns and make them not depend on the global path
 2014-08-08 16:33:44 -04:00
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 325f9ef005 Make create atomic on etcd for Services/ReplControllers 2014-08-05 01:12:27 -04:00
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.

minor changes

Fixed a minor rebase issues.

Using ioutil.ReadAll instead of httputil.DumpResponse

Daniel Smith 69c483f620 Add APIObject for generic inclusion of API objects. 
Includes test and json/yaml getters and setters.

Daniel Smith eda30d4f20 Add watch mechanism to apiserver 
Implemented via HTTP and websocket. A test is present but this isn't
yet wired into anything.

Eventual purpose of this is to allow a scheduler to watch for new pods.
Or allow replication controller to watch for new items it controlls.
Generally, it'll be good to turn everything possible into a push instead
of a poll.

Clayton Coleman 0ccf1b7812 Operation server was not returning in error cases 2014-07-18 12:36:27 -04:00
Yuki Yugui Sonoda 2aa3de12d4 Make RESTful operations return 404 Not Found when the target resource 
does not exist.

In the original implementation, GET, DELETE and PUT operations on
non-existent resources used to return 500 but not 404.

Daniel Smith 3b9735d787 Test atomic PUTs, and make them work. 
Improve apiserver/logger.go's interface (it's pretty cool now).

Improve apiserver's error reporting to clients.

Improve client's handling of errors from apiserver.

Make failed PUTs return 409 (conflict)-- http status codes are amazingly
well defined for what we're doing!

Tim Hockin 9f9e75f508 Switch to glog for logging, bridge logging to glog. 
1) imported glog to third_party (previous commit)
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.
