Cleanup the errors and removed deadcode along the way. The leaves
some error laying around, mostly about commenting exported identifier.
We should look hard if those really are needed.
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 :)
Stop the caddy message and start our own init notifications.
Log the version of CoreDNS when starting up.
Fix all middleware's setup functions so that return the error prefixed
with *which* middleware was failing; leads to better debuggable errors
when starting up.
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
* 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.
Changes large parts of proxy lookup mechanism.
The duplicate zone checking erroneous added a nameserver for each
zone we are auth. for, creating to many backend hosts. So even when a
host was determined do be Down() we still got an (identical) new one
from the list.
The Down() and failure checking for upstream hosts had data race in the
uh.Fails check - we now use atomic.LoadInt32 for that.
Use and debug the test/server.go test servers implementation in the
TestStubLookup test to prevent going out to the internet.
Also delete the stub cycle test. That test was wrong and did not test
what it needed to be testing. Deleted for now.
* Changed reference to Caddy over to CoreDNS
* Removing references to caddy
* Fixed misleading error message to reference coredns
* Cleaning up references to caddy
* Adding clean and deps targets
Muscle memory is resulting in "make clean" commands.
* Adding test target to makefile
* More "Caddy" cleanup
Return a delegation when seeing one while traversing the tree in
search of an answer.
Put the SOA and NS record in the zone.Apex as these are to be handled
somewhat special.
Lowercase record on insert to make compares easier. This lowercases
all RR that have domain names in their rdata as well.
Instead of watching a single file watch the entire directory and
catch the .Name from the event. On any event, just reload the damn
thing. This also fixes the problem of loosing events when the inode
changes.
Error out when parsing and transferring such a zone. If we would serve
it we would give out the wrong answers, leading to (probably) validation
failures...
Fixes#114
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
We should not check the port of the request, we *should* actually
normalize it to port 53 - as that will probably be the address of
the server. Still need to double check if this will work if the
axfr should actually be done from a different port. That will come
later, this is good enough for now.
Test shouldTransfer by upping a testserver and sending the SOA query.
Remove state from DefaultErrorHandler and just get it from the request.
Add more logging to show what is going on.
This also adds the infrastructure for future tests.
For prometheus use the plain value, not a pointer and change all usages.
Allow AXFR to be requested over udp as well and some other more log
printed when commencing an AXFR.
Respond to notifies and allow a secondary to follow the SOA parameters
to update a zone from a primary. Also sprinkle it with logging.
Also extend monitoring to include qtype in more metrics.
Make the CH middleware actually work. Needs a bit of a hack to route
the fake version.bind and friends zone to the correct handler. Fiddle
with the order in directive.go so that CH queries get logged as well.
Secondly add class rewriting to the rewrite middleware handler and also
log the class by default.
Cache the size and the do bit whenever someone asked for it. We can
probably add more:

This PR also includes some testing cleanups as well.
Fix some file/secondary issues when parsing a Corefile, also allow
for multiple origins to be specified. Also don't fail on startup when
a zonetransfer fails.
Fixes: #54
Allow specifying a primary server and retrieve the zone's content.
Add tests and an Expired bool to zone struct, to stop server zones
that are expired. The zone is retrieved on Startup, no updates of
changed content are done. We also don't respond to notifies yet.
Drop the use of dns.RR when in fact the only thing we use is the name
and type of the RR. Cleans up a bunch of stuff and also stops the weird
making of dns.RRs just for a lookup. Should safe some memory as well.
Fixes: #66
When looking for a name in tree, return wether we got to a longer one -
if so we had an ent. Add tests + dnssec tests and refactor the tests as
well a bit.
Reply to queries when you have a wildcard in the zone. This works
for DNS and DNSSEC. Thing missing is NODATA responses for that specific
wildcard.
Add wildcard_test.go as well.
