* 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
* 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
* healthchecks: check on every 3rd failure
Check on every third failure and some cleanups to make this possible. A
failed healthcheck will never increase Fails, a successfull healthceck
will reset Fails to 0. This is a chance this counter now drops below 0,
making the upstream super? healthy.
This removes the okUntil smartness and condences everything back to 1
metrics: Fails; so it's simpler in that regard.
Timout errors are *not* attributed to the local upstream, and don't get
counted into the Fails anymore. Meaning the 'dig any isc.org' won't kill
your upstream.
Added extra test the see if the Fails counter gets reset after 3 failed
connection.
There is still a disconnect beween HTTP healthceck working the proxy (or
lookup) not being able to connect to the upstream.
* Fix tests
* 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
