2018-10-09plugin/kubernetes: allow trimming down of cached items. (#2128)Gravatar Miek Gieben 21-983/+1155
* Convert to runtime.Object to smaller structs This adds conversion for all the objects we want to keep in the cache. It keeps the minimum for CoreDNS to function and throws away the rest. The conversion: api.Endpoints -> object.Endpoints api.Pod -> object.Pod api.Serivce -> object.Service We needed to copy some client-go stuff to insert a conversion function into NewIndexInformers. Some unrelated cleanups in the watch functionality as that needed to be touched because of the above translation of objects.

2018-09-19Ensure Re-register of metrics variables after a reload (#2080)Gravatar Francois Tur 12-39/+9
* - ensure plugins that use prometheus.MustRegister, re-register after reload - removing once.Do on the startup function was simplest way to do it. * - fix underscored names (advice of bot) * - tune existing UT for reload, and add a test verifying failing reload does not prevent correct registering for metrics * - ensure different ports for tests that can run in same time ..
2018-09-19Better naming (#2104)Gravatar Miek Gieben 12-79/+90
* Move functions from pkg/transport to pkg/parse Although "parse" is a fairly generic name I believe this is somewhat better named. pkg/transport keeps a few constants that are uses throughout for the rest is is renaming a bunch (and the fallout from there to make things compile again). Signed-off-by: Miek Gieben <miek@miek.nl> * Fix tests Signed-off-by: Miek Gieben <miek@miek.nl>
2018-09-19Cleanup ParseHostOrFile (#2100)Gravatar Miek Gieben 17-130/+150
Create plugin/pkg/transport that holds the transport related functions. This needed to be a new pkg to prevent cyclic import errors. This cleans up a bunch of duplicated code in core/dnsserver that also tried to parse a transport (now all done in transport.Parse). Signed-off-by: Miek Gieben <miek@miek.nl>

2018-09-17[plugin/proxy]: Return on WriteMsg err. (#2096)Gravatar dilyevsky 1-8/+5
* [plugin/proxy]: Return on WriteMsg err. Followup PR on the heels of #2050. Short-circut and log on error from `WriteMsg`. This will prevent code getting stuck on `ReadMsg` and allow for easier debugging. Also simply the `ReadMsg` calling code a little - remove double `Close` (already called above).

2018-08-29Default to scrubbing replies in the server (#2012)Gravatar Miek Gieben 23-119/+28
Every plugin needs to deal with EDNS0 and should call Scrub to make a message fit the client's buffer. Move this functionality into the server and wrapping the ResponseWriter into a ScrubWriter that handles these bits for us. Result: Less code and faster, because multiple chained plugins could all be calling scrub and SizeAndDo - now there is just one place. Most tests in file/* and dnssec/* needed adjusting because in those unit tests you don't see OPT RRs anymore. The DNSSEC signer was also looking at the returned OPT RR to see if it needed to sign - as those are now added by the server (and thus later), this needed to change slightly. Scrub itself still exist (for backward compat reasons), but has been made a noop. Scrub has been renamed to scrub as it should not be used by external plugins.

2018-07-22plugin/loop: add missing break (#1992)Gravatar Miek Gieben 1-2/+4
The Onstartup loop wouldn't call break after the first success, thereby sending the query multiple times and halting the process. Some small other optimizations as well. Signed-off-by: Miek Gieben <miek@miek.nl>
2018-07-20New plugin: loop (#1989)Gravatar Miek Gieben 9-0/+269
* New plugin: loop Add a plugin that detects loops. It does this by sending an unique query to our selves. If we see the query more than twice we stop the process. If there isn't a loop, the plugin disables it self and becomes a noop plugin. Signed-off-by: Miek Gieben <miek@miek.nl>
