* core: remove HostAddresses()
config.HostAddresses() is a weird function that gathers
some data from the server and returns a string.
It is *only* used the trace plugin, to figure out what
server starts the trace.
Looks to be better to fit in the with metrics.WithServer label
on the trace itself to show which server handled the trace.
Remove HostAddresses() and cleanup trace a small bit.:w
* lint
* add OverlapChecker, move the test of overlap AFTER the directive setup process, change key of configs to allow multiple same key
* glitch when rebase. init of Config should include the default host
* add tests for the registering of configuration
rename multicast in 'unbound'.
add comments on the validator
* - merged zoneAddr and addrKey that are very similar
- move maps of Validator to zoneAddr, avoinding need to have string representation of zoneaddr
- moving key build for saving Config at Config side instead of dnsContext
* - UT on saving config is now useless.
* - cannot cleanup access to Configs after setup. Deferred function to Start, use it
* - cleanup register unit tests. remove useless function
* - address comments of review. name of validator, comments, simplify registerAndCheck
* - fixes after review. renaming a function and a comment
* Extend bind to allow multiple addresses. UTs added. Changes the log for server starting, adding address when available
* update readme for bind
* fixes after review
* minor fix on readme
* accept multiple BIND directives in blocserver, consolidate the addresses
* fixes after review - format logging server address, variable names
* 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:

* README.md updates
* 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
block chaos queries, unless the chaos or proxy middleware is loaded. We
respond with REFUSED.
This removes the need for each middleware to do this class != ClassINET
if-then.
Also make config.Registry non-public.
* core: replace GetMiddleware
See the discussion in #881. GetMiddleware would add a `nil` middleware
to the callstack thereby breaking functionality.
This PR drops it in favor of RegisterHandler which is a completely
standalone registry for middleware that want to let it self know to
other middleware.
Currenly *autopath* uses this to call *kubernetes*'s AutoPath method
for dynamic autopathing.
* Drop GetMiddleware
* Register metrics
* drop the panic
* middleware/debug: add
Add a debug "middleware" that disables the recover() and just lets
CoreDNS crash; very useful for testing.
Fixes ##563
* fix test
* Feedback: check the value of Debug
* core: add listening for other protocols
Allow CoreDNS to listen for TLS request coming over port 853. This can
be enabled with `tls://` in the config file.
Implement listening for grps:// as well.
a Corefile like:
~~~
. tls://.:1853 {
whoami
tls
}
~~~
Means we listen on 1853 for tls requests, the `tls` config item allows
configuration for TLS parameters. We *might* be tempted to use Caddy's
Let's Encrypt implementation here.
* Refactor coredns/grpc into CoreDNS
This makes gRPC a first class citizen in CoreDNS. Add defines as being
just another server.
* some cleanups
* unexport the servers
* Move protobuf dir
* Hook up TLS properly
* Fix test
* listen for TLS as well. README updates
* disable test, fix package
* fix test
* Fix tests
* Fix remaining test
* Some tests
* Make the test work
* Add grpc test from #580
* fix crash
* Fix tests
* Close conn
* README cleanups
* README
* link RFC
The gRPC server middleware[1] needs access to the Server object
in order to push the unpacked Msg through the normal middleware
pipeline. These are the changes to core needed to make that
possible.

* middleware/metrics: add more metrics
middleware/cache:
Add metrics for number of elements in the cache. Also export the total
size. Update README to detail the new metrics.
middleware/metrics
Move metrics into subpackage called "vars". This breaks the import
cycle and is cleaner. This allows vars.Report to be used in the
the dnsserver to log refused queries.
middleware/metrics: tests
Add tests to the metrics framework. The metrics/test subpackage allows
scraping of the local server. Do a few test scrape of the metrics that
are defined in the metrics middleware.
This also allows metrics integration tests to check if the caching and
dnssec middleware export their metrics correctly.
* update README
* typos
* fix tests
This PR adds the *root* middleware that specifies a path where
all zone file (the *file* middleware is the only consumer now) can
be found. It works the same as in Caddy.
Documentation can be found in the README.md of the middleware.
Fixes#307
For some reasons there was a dnsserver/middleware.go that defined
the middleware handlers. This code was a repeat from
middleware/middleware.go. Removed dnsserver/middleware.go and replaced
all uses of dnsserver.Middleware with middleware.Middleware.
Added dnsserver/address_test.go to test the zone normalization (and to
improve the test coverage). The deleted file will also improve the test
coverage :)
* 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.
