* cidr everywhere: check all middleware
Add tests for cidr in only that middleware that already tests for this.
Check the other ones manually (and put reverse in the tests cases
anyway).
Make etcd setup_test run without +build etcd tag - it is not needed
for this test - move rest of the code to lookup_test.go.
Cleanup proxy test a bit and remove TempDir as there is test.TempFile
that does the same thing.
Fixes#909
* coredns package
* Fix test compile
* Switches out Unhealthy bool for OkUntil timestamp
* Make sure servers are healthy forever if there are no health checks
* Moves health check off into a go routine to avoid blocking conditions
* Improved logging info
* Fixes initial date
* Fixes health checking; alters tests to adapt to async health checking
* Moves future variable into static upstream and populates it in more places
* Restores silencing of stdout during testing
* Restores silencing of stdout during testing
* keeps check url string once built
* Removes debug message
* uses zero value to signal no checking; reduces in-mutex code to a fetch
* Revert "middleware/proxy: Make Unhealthy a pointer (#615)"
This reverts commit acbf522ceb.
* middleware/proxy: add proper locking
This add the proper locking around `Unhealthy`.
Pointer updates are atomic so drop the sync.RWMutex as it is not needed
anymore. This also fixes the race introduced with dfc71df (although I
believe this is the first time we properly tested that code path).
* add proxy tcp
* add truncated for tcp to udp response
* move truncation to scrubbing
* add test that executes upstream over tcp
* middleware/proxy: some tweaks
rename force-tcp to force_tcp to be inline with the rest and use
a dnsOptions struct to put the options in to allow it to be extended.
Add some parse tests as well.
* Fix test and rename dnsOptions Options
* WIP: Client-side of gRPC proxy
* Add tests
* gofmt
* Implement OnShutdown; add a little logging
* Update for context in Exchange change
* go fmt
* Update README
* Review comments
* Compiling is good
* More README improvements
Fix the except keyword usage - the config would allow it, but it was
not enforced in the code.
Turns out that **FROM** was also not enforced, fix both, by (basically)
copying the code from Caddy.
Update the README and tests.
Locally test as well, shows that this works:
~~~
.:1053 {
proxy miek.nl 8.8.8.8:53 {
except a.miek.nl
}
proxy a.miek.nl 8.8.4.4:53
errors stdout
log stdout
}
~~~
And gives the desired results, not having a proxy line for `a.miek.nl`
results in a SERVFAIL (as expected).
Fixes#502
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
This fix tries to fix 261 where proxy upstream parser is not
able to parse upstream correctly.
Several test cases have also been added to cover the changes
and prevent regression in the future.
This fix fixes 261.

* middleware/proxy: add spray keyword
When spray is used, the proxy will, when all backend are down, spray to
each target. When not used, default to the old defaults: max 1 failure
and no spray. These defaults are also used when forwarding queries to
another CoreDNS instance.
Update the README with the new keyword.
* typos
* Make MaxFail = 1 again
* more reversals
