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

Tim Hockin 23fc00be5c Fix a race in proxy. 
addService() eventually calls getServiceInfo(), but the serviceInfo object may
not be installed yet (race).

Brendan Burns da74625ac6 Fix the proxier when a service with the same port is re-created, actually restart the proxy. 2014-08-19 12:24:10 -07:00
Kouhei Ueno 2e02967aca Avoid data race in Proxier.OnUpdate 
The bug was that the proxier is passed as value on method decleration.
This caused a copy of Proxier to be created when the method was invoked.
The copy being a shallow copy turned out to have them both reference
a same map instance, but their mutexes were different instances.
This turned out to use different mutexes before operating on a same map
instance, which didn't make sense.

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.
