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.

Respond to AXFR queries
* Fixing race condition
* Fixing instantiation of dnstest writer

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.

Let caddyfile parser give us the token, the comma sep thing also didn't
work.

These can be just vars. Think that was intended as well.

* Simplify plugin/pkg/fall

* 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.

* Add zone filtering to fallthrough
* Doh. gofmt
* Update documentation

Fixes #1331

We already do the right thing here, but add a test none-the-less.

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.

* ipv6 UT for endpoint
* tweak
|
|
Remove most 303 TTLs (those get skipped by the test) and use 5, which is
the default for all tests.
|
|
The TTL was still zero, instead it should adhere to the k.ttl setting.
Change this and update tests to match.
|

* clean up and add some ipv6 tests
* aaaa endpoint
* gofmt

|
* 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

Check the error returned by clientConfig.ClientConfig() before trying to
set cc.ContentType.

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.

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
|
|
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.

If we don't need it, don't initialize it.

* 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:

* plugin/kubernetes: wait until api is ready
Wait for HasSynced before allowing startup to avoid startup race.
Also do a small refactor in findServices() to pull a check out of the
loop - only needs to be done once.

* healthchecks: check on every 3rd failure
Check on every third failure and some cleanups to make this possible. A
failed healthcheck will never increase Fails, a successfull healthceck
will reset Fails to 0. This is a chance this counter now drops below 0,
making the upstream super? healthy.
This removes the okUntil smartness and condences everything back to 1
metrics: Fails; so it's simpler in that regard.
Timout errors are *not* attributed to the local upstream, and don't get
counted into the Fails anymore. Meaning the 'dig any isc.org' won't kill
your upstream.
Added extra test the see if the Fails counter gets reset after 3 failed
connection.
There is still a disconnect beween HTTP healthceck working the proxy (or
lookup) not being able to connect to the upstream.

Go through all README and fix mistakes, extend example and let more
corefile snippets be test for validity.

* healhcheck: various cleanups
Network wasn't used. IgnorePaths wasn't used. Move checkdown function to
common function shared between proxy protocols. And some naming fixed.
Also reset the Fails on a succesful healthcheck back to 0.

Add a full test server impl in this new package + tests. Move
dnsrecorder into this package as well and finish up the commented out
tests that were left in the old dnsrecorder package.
Update all callers and tests.

updates so the look better on coredns.io

* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error

* Readd AddMiddleware to remain backwards compat
