* Remove Compress by default
Set Compress = true in Scrub only when the message doesn not fit the
advertized buffer. Doing compression is expensive, so try to avoid it.

* plugins: use plugin specific logging
Hooking up pkg/log also changed NewWithPlugin to just take a string
instead of a plugin.Handler as that is more flexible and for instance
the Root "plugin" doesn't implement it fully.
Same logging from the reload plugin:

* update docs
* better doc
* global: move to context
Move from golang.org/x/net/context to std lib's context.
Change done with:
for i in $(grep -l '/context' **/*.go); do sed -e 's|golang.org/x/net/context|context|' -i $i; echo $i; done
for i in **/*.go; do goimports -w $i; done
* drop from dns.pb.go as well
* Update all plugins to use plugin/pkg/log
I wish this could have been done with sed. Alas manually changed all
callers to use the new plugin/pkg/log package.
* Error -> Info
* Add docs to debug plugin as well
This PR documents the trick exposed in coredns/coredns#1357 about using wildcards to get all POD IPs from a service with ClusterIP (as used in 'endpoints')
* plugins: Return error for multiple use of some
Return plugin.ErrOnce when a plugin that doesn't support it, is called
mutliple times.
This now adds it for: cache, dnssec, errors, forward, hosts, nsid.
And changes it slightly in kubernetes, pprof, reload, root.
* more tests
Rename the constants to IP4arpa and IP6arpa (shorter and exported) and
make IsReverse return the type of the reverse zone which could be handy
for some callers.
Also add tests for IsReverse()
Remove `fallthrough` from the federation example in the README. `fallthrough` isn't needed here and has no effect (federation has an implicit fallthrough for non-federated queries).
It's inclusion is confusing.
* plugin/kubernetes: axfr
Hook up dynamic SOA serial by setting ResourceEventHandlerFuncs in
dnsController.
Add prototype of returns msg.Services via the Transfer function. Leave
expanding this to RRs out of scope for a bit.
* plugin/kubernetes: axfr
Respond to AXFR queries
* Fixing race condition
* Fixing instantiation of dnstest writer
* Updates from review
This should have everyone, but the process was quite manual. The rename
from middleware -> plugin also meant I had to do some extra digging on
who actually submitted the PR. I also double checked the current list of
people with commit access.
Every plugin now has an OWNERS, except *reverse*. I'll file a bug for
that.
* Add pkg/fall for Fallthrough
Move this into it's own package to facilitate tests. Important bug
was fixed: make the names fully qualified.
Add fall package to hosts, reverse, etcd, and fix kubernetes and any
tests. The k8s tests are still as-is, might need a future cleanup.
This is probably the first in a series to fix "crazy" pod queries.
If the namespace doesn't exist return NXDOMAIN.
It might be worth extending this 1:1 to findServices as well.
* Add manual pages
Generate manual pages from the README and extend README with Name and
Description sections.
The generation requires 'ronn' which may not be available. Just check in
all generated manual pages.
* Update k8s client-go to v6.0.0
This fix updates k8s client-go to v6.0.0 as CoreDNS is supported
in 1.9 and v6.0.0 is the recommended version.
There are quite some massive changes that need to be made:
1. k8s.io/client-go/pkg/api/v1 has been changed to k8s.io/api/v1 (repo changed from `client-go` to `api`)
2. kubernetes.Clientset adds one extra layer, so that `kubernetes.Clientset.Services()` and like has been changed to `kubernetes.Clientset.CoreV1().Services()`
Also, we have to stick with specific commits of `k8s.io/apimachinery` and the newly introduced `k8s.io/api`
because go dep still could not figure out the right version to fetch.

* Update vendor with `dep ensure --update` and `dep prune`
Signed-off-by: Yong Tang <yong.tang.github@outlook.com>
* plugin/kubernetes: Add GetNamespaceByName
A bare or wildcard query for just the namespace should return NODATA,
not NXDOMAIN, otherwise we deny the entirety of the names under the
namespace.
Add test to check for this in pod verified mode.
* Review
More comments and move namespace code to namespace.go
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
