Add support for running profiling when debug build-tags provided (#491) 
* wrap root HTTP handler in debug.WithPprof(), rearrange router.Start() to support this
* remove unused code
* set debug buildtag in build script when $DEBUG set
* update go-debug version with fixed handler
* use clone of router.srv for LE cert manager, reset server timeouts in debug
* add kim's other libraries to README

go-debug

This library provides a very simple method for compile-time or runtime determined debug checks, set using build tags.

The compile-time checks use Go constants, so when disabled your debug code will not be compiled.

The possible build tags are:

  • "debug" || "" = debug determined at compile-time

  • "debugenv" = debug determined at runtime using the $DEBUG environment variable

An example for how this works in practice can be seen by the following code:

func main() {
	println("debug.DEBUG() =", debug.DEBUG())
}

# Debug determined at compile-time, it is disabled
$ go run .
debug.DEBUG() = false

# Debug determined at compile-time, it is enabled
$ go run -tags=debug .
debug.DEBUG() = true

# Debug determined at runtime, $DEBUG is not set
$ go run -tags=debugenv .
debug.DEBUG() = false

# Debug determined at runtime, $DEBUG is set
$ DEBUG=y go run -tags=debugenv .
debug.DEBUG() = true
