* global: move to context
Move from golang.org/x/net/context to std lib's context.
Change done with:
for i in $(grep -l '/context' **/*.go); do sed -e 's|golang.org/x/net/context|context|' -i $i; echo $i; done
for i in **/*.go; do goimports -w $i; done
* drop from dns.pb.go as well
* Update all plugins to use plugin/pkg/log
I wish this could have been done with sed. Alas manually changed all
callers to use the new plugin/pkg/log package.
* Error -> Info
* Add docs to debug plugin as well
* prevent nil pointer when query frpc client that could not open
* add UT checking we can now safely request DNS query on an invalid hostname, query for gRPC connection
* fix ortograph
* fix format
* fix package declaration, fix UT - grpclogger, use fatalf, build pool with known addresses
* type, useless error check - after review
With Go 1.9 you *can* include the std lib's context package and nothing
breaks. However we never officially made the move (and grpc also doesn't
ues the std lib's one).
Standardize all plugins on using the extern context package.
Fixes#1466
* 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
