This is needed as well to make it compile cleanly. Follow up to #3214.
Manually removed github.com/coreos/etcd/ from go.mod

* Move *proxy* to external
move the proxy plugin into coredns/proxy and remove it as a default
plugin. Link the proxy to deprecated in plugin.cfg
coredns/proxy doesn't compile because of the vendoring :(

* Default to upstream to self
This is a backwards incompatible change.
This is a massive (cleanup) PR where we default to resolving external
names by the coredns process itself, instead of directly forwarding them
to some upstream.
This ignores any arguments `upstream` may have had and makes it depend
on proxy/forward configuration in the Corefile. This allows resolved
upstream names to be cached and we have better healthchecking of the
upstreams. It also means there is only one way to resolve names, by
either using the proxy or forward plugin.
The proxy/forward lookup.go functions have been removed. This also
lessen the dependency on proxy, meaning deprecating proxy will become
easier. Some tests have been removed as well, or moved to the top-level
test directory as they now require a full coredns process instead of
just the plugin.
For the etcd plugin, the entire StubZone resolving is *dropped*! This
was a hacky (but working) solution to say the least. If someone cares
deeply it can be brought back (maybe)?
The pkg/upstream is now very small and almost does nothing. Also the
New() function was changed to return a pointer to upstream.Upstream. It
also returns only one parameter, so any stragglers using it will
encounter a compile error.
All documentation has been adapted. This affected the following plugins:
* etcd
* file
* auto
* secondary
* federation
* template
* route53
A followup PR will make any upstream directives with arguments an error,
right now they are ignored.

* Clean up tests logging
This cleans up the travis logs so you can see the failures better.
Older tests in tests/ would call log.SetOutput(ioutil.Discard) in
a haphazard way. This add log.Discard and put an `init` function in each
package's dir (no way to do this globally). The cleanup in tests/ is
clear.
All plugins also got this init function to have some uniformity and kill
any (future) logging there in the tests as well.
There is a one-off in pkg/healthcheck because that does log.

* Update dependencies and add etcdv3 client
* Update etcd plugin to support etcd v3 clients
Fixes #341
|

Fix the casing *and* fix use of context as we were still referencing
the non-std lib context - no wondering how this could have worked...
|
|
Forgot about these.
|
|
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
|
|
* tests: CoreDNSServerAndPorts
Copy from kubernetes.go and renamed to fit the style, adapted almost
all callers.
This is a mechanicl change, no testdata was changed.
* typos
|
|
* mw/kubernetes: remove federation and cidr
Remove both as we have a corefile syntax change that handles cidr and
remove federation because that is going to be its own middleware.
* backwards incompat changes
This PR:
* removes cidr from kubernetes (core Corefile feature now)
* removes federation from kubernets (comes back as new middleware)
* [remove autopath - which was already gone, so that already was
backwards incompat]
* adds `fallthrough` to the *etcd* middleware and makes you enable it.
* Fail on unknown properties
* documentation
* Disable TestHealthCheck as it uses realtime and fails

(#547)
This fix fixes import path from
`github.com/miekg/coredns`
->
`github.com/coredns/coredns`
|
|
This fix fixes several `go fmt`, `go lint`, and `go vet` issues,
to make goreportcard happy:

By defining and using an proxy.Exchanger interface we make the proxy
more generic and we can then fold back httproxy into proxy.
This overrides #463 and #473 and should make futures extensions rather
trivial
* Add docs that talk about `protocol` and how to set it.
* middleware/proxy: rename New to NewLookup
It's used as a Lookup mechanism not as a completely new proxy,
reflect that in the name.
* Set maxfails to 3 by default when looking up names.
Most of the changes have been copied
from https://github.com/johnbelamaric/coredns/pull/1/files

Create a small speedup running the tests:
PASS
ok github.com/miekg/coredns/test 10.329s
PASS
ok github.com/miekg/coredns/test 6.079s
Skip the etcd ones. Doing the middleware/*/*_test ones doesn't yield
any speedup as these are still done on a per directory basis.
|
|
Add a test which enables caching and debug queries and make sure
the debug query does not overwrite the cache.
|
|
Make the cache memory bounded, by using a LRU cache. Also split the
cache in a positive and negative one - each with its own controls.
Extend the cache stanza to allow for this:
cache {
positive limit [ttl]
negative limit [ttl]
}
is now possible. This also add a cache_test.go in the toplevel test/
directory that exercises the caching path.
Fixes #260

Move all (almost all) Go files in middleware into their
own packages. This makes for better naming and discoverability.
Lot of changes elsewhere to make this change.
The middleware.State was renamed to request.Request which is better,
but still does not cover all use-cases. It was also moved out middleware
because it is used by `dnsserver` as well.
A pkg/dnsutil packages was added for shared, handy, dns util functions.
All normalize functions are now put in normalize.go

* Set version to 001
* Remove k8stest, test fails is k8s is not there: touch luck
* Remove server directory: not used anymore
* Disable k8s test (for now)
* gometalinter changes
|
|
* Make CoreDNS a server type plugin for Caddy
Remove code we don't need and port all middleware over. Fix all tests
and rework the documentation.
Also make `go generate` build a caddy binary which we then copy into
our directory. This means `go build`-builds remain working as-is.
And new etc instances in each etcd test for better isolation.
Fix more tests and rework test.Server with the newer support Caddy offers.
Fix Makefile to support new mode of operation.

Make the receiver a pointer so that the uptdateStubZones map update will
retain the stubzones found, unlike the current case where the update
will be applied and then promptly forgotten, because it is working on a
copy.
Add test/etcd_test.go to test a large part of the code. This didn't
catch the chaos middleware hack though. The chaos middleware zones are
now *not* automatically added. You have to take care of that by yourself
(docs updates).
When using debug queries and falling through to the next middleware in
etcd, restore the original (with o-o.debug) query before passing it on.

Add a fullblown testing server. This allows us to do integration tests.
Also add a basic proxy test. Further tests will test etcd proxy
and stub zone communication and other "wildish" configurations.
Redo the server startup, so we can access the ports it listens on when
it has started up (with dns.ActivateAndServer).
Extend the .travis file to download etcd and test for that as well.
Put integration tests in test dir
