* go modified fiddling with vendor got rid of the vendor directory revendored but with the exact same versions of things maybe better added mods for the images revendored using `GOFLAGS` instead of repeating my self vendor everything to the exact same commit hash as before and fixed ugorji Delete Deproxy.toml empty file cleaned up some file cleaned up some cruft get rid of some unused packages and exclude some Microsoft packages added flags to the variables that get pushed into docker in the makefile It works I suppose added noop excluded what we did not want even less hacky reverted to a version that has not been mangled * get rid of my experiment
errors 
Package errors provides simple error handling primitives.
go get github.com/pkg/errors
The traditional error handling idiom in Go is roughly akin to
if err != nil {
return err
}
which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
Adding context to an error
The errors.Wrap function returns a new error that adds context to the original error. For example
_, err := ioutil.ReadAll(r)
if err != nil {
return errors.Wrap(err, "read failed")
}
Retrieving the cause of an error
Using errors.Wrap constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by errors.Cause.
type causer interface {
Cause() error
}
errors.Cause will recursively retrieve the topmost error which does not implement causer, which is assumed to be the original cause. For example:
switch err := errors.Cause(err).(type) {
case *MyError:
// handle specifically
default:
// unknown error
}
