Implement health.Healther in erratic and kubernetes plugin. The
kubernetes' healtcheck is only performed on startup - i.e. turn
healthy after the initial loading.
Erratic follow the drop count: every query%drop turns the healthcheck
unhealthy.
Fixes: #985
* plugin/log: remove need to specify stdout
Since log will only be output to stdout is doesn't make sense to
specify it in Corefile.
Fixes: #1218
* fixup! plugin/log: remove need to specify stdout
I think this badge is misleading as we are not a library so the number of projects we are used in is not really relevant to our adoption. It is more-or-less just the number of external plugins people have built.
* Update zipkin to the newer version
Also update thrift to use head commit

Change to use a new 'endpoints' directive and use a constant
Add initial docs for 'endpoints' directive
Add tests to Kubernetes setup for endpoints
Changes based on PR feedback
endpoint_pod_names is a boolean config option. Chahanged docs to reflect this.
Add a test when endpoints_pod_names is not set
Update README.md
Remove endpointNameModeName as it is no longer used
This fix is an attempt to fix the issue raised #1192.
The issue that a plain `dep -ensure update` fails is because
the incompatibility of ugorji/go with the rest of packages (etcd, k8s etc)
and the incompatibility of client-go vs. apimachinery.
This fix fixed apimachinery and ugorji/go so that it is possible
to use `dep -ensure update`.
Previously updates has to be done individually, e.g.,
`dep -ensure update github.com/coreos/etcd`
This fix fixes#1192.

While we at it, why not add a target for Windows as well.
This also introduces a VERBOSE option that defaults to -v, but it empty
when releases so that you can actually see what you're building.
Move an @echo out of shell snippet into the Makefile, as that errored
with @echo: command not found.

This fix updates vendor libraries except client-go, apimachinery
and ugorji/go, as github.com/ugorji/go/codec is causing compatibilities issues.

In Makefile.release `shell uname -m` was used to find the current architecture.
On amd64 systems this might be reported as `x86_64` depending on the Linux.
However, in order to have manifest docker images we need to stick with
golang's architecture tag of `amd64`.
This fix changes instead so that the correct architecture conforming to
golang (`amd64`) could be build.

Add a dynamic SOA record (at least the serial and minttl). This create
another interface that should be implemented by the backends.
For now default to returning epoch in as a uint32 (no change from
before).
Lower the minTTL returned to 30s (from 60s)
Fix typo in kubernetes/README.md and remove DEV-README.md as it is stale
and information on the website is more up to date.
Remove large sections of text in plugin.md; just talk about how to
structure your plugin and docs.
* readme: more tests
Add dnssec and file plugin to the test readme. This requires creating a
bunch of files with the right content. Doing so already unconvered an
unconditional type assertion in DNSSEC. This PR will include the fix for
that as well.
Also extended the snippets in the file plugin README, so that they are
whole Corefile - showing more value and checking all corefile snippets.
Create outliner right now is the kubernetes plugin, because even setting
the right env vars will result in:
open /var/run/secrets/kubernetes.io/serviceaccount/token: no such file or directory":
Which we can't create for a test.
* lint
Don't use the 'check and godep' target when building for a release, this
is now repeated 6 times for no reason as this is already checked on
travis.
Some other cleanups in the documentation as well.
* integration ci
* rename test
* unfunctionalize DoIntegrationTests
* alphabetize expected answers
* Enable out-of-cluster test
* Enable out-of-cluster test
* move integration tests back to ci repo
Some cleanup in proxy and dnstap:
* just use time pkg directly and side step the indirection for Epoch
* Use Set in SetQueryEpoch to be more Go like. (Looked like a reader)
* Don't maintain two sets of time, we already track start, so use that.
* Use time.Time and convert when needed
* dedent the toDnstap function and put in a separate file
* core: allow all CIDR ranges in zone specifications
Allow (e.g.) a v4 reverse on a /17. If a zone is specified in such a
way a FilterFunc is set in the config. This filter is checked against
incoming queries.
For all other queries this adds a 'x != nil' check which will not impact
performace too much. Benchmark function is added as well to check for
this as wel.
Add multiple tests in tests/server_reverse_test.go.
Benchmark shows in the non-reverse case this hardly impact the speed:

I've added two new labels: wontfix-stalebot and pinned.
Wontfix-stalebot will be used by stalebot and pinned can be used to keep
