The problem +with this pattern is that you completely lose the original `error` structure. + +Arguably the _correct_ approach is that you should make a custom structure +implementing the `error` interface, and have the original error as a field +on that structure, such [as this example](http://golang.org/pkg/os/#PathError). +This is a good approach, but you have to know the entire chain of possible +rewrapping that happens, when you might just care about one. + +`errwrap` formalizes this pattern (it doesn't matter what approach you use +above) by giving a single interface for wrapping errors, checking if a specific +error is wrapped, and extracting that error. + +## Installation and Docs + +Install using `go get github.com/hashicorp/errwrap`. + +Full documentation is available at +http://godoc.org/github.com/hashicorp/errwrap + +## Usage + +#### Basic Usage + +Below is a very basic example of its usage: + +```go +// A function that always returns an error, but wraps it, like a real +// function might. +func tryOpen() error { + _, err := os.Open("/i/dont/exist") + if err != nil { + return errwrap.Wrapf("Doesn't exist: {{err}}", err) + } + + return nil +} + +func main() { + err := tryOpen() + + // We can use the Contains helpers to check if an error contains + // another error. It is safe to do this with a nil error, or with + // an error that doesn't even use the errwrap package. + if errwrap.Contains(err, "does not exist") { + // Do something + } + if errwrap.ContainsType(err, new(os.PathError)) { + // Do something + } + + // Or we can use the associated `Get` functions to just extract + // a specific error. This would return nil if that specific error doesn't + // exist. + perr := errwrap.GetType(err, new(os.PathError)) +} +``` + +#### Custom Types + +If you're already making custom types that properly wrap errors, then +you can get all the functionality of `errwraps.Contains` and such by +implementing the `Wrapper` interface with just one function. Example: + +```go +type AppError { + Code ErrorCode + Err error +} + +func (e *AppError) WrappedErrors() []error { + return []error{e.Err} +} +``` + +Now this works: + +```go +err := &AppError{Err: fmt.Errorf("an error")} +if errwrap.ContainsType(err, fmt.Errorf("")) { + // This will work! +} +``` diff --git a/vendor/github.com/hashicorp/errwrap/errwrap.go b/vendor/github.com/hashicorp/errwrap/errwrap.go new file mode 100644 index 000000000000..a733bef18c05 --- /dev/null +++ b/vendor/github.com/hashicorp/errwrap/errwrap.go @@ -0,0 +1,169 @@ +// Package errwrap implements methods to formalize error wrapping in Go. +// +// All of the top-level functions that take an `error` are built to be able +// to take any error, not just wrapped errors.

If the caller knows this, they can unwrap the +list and access the errors. If the caller doesn't know, the error +formats to a nice human-readable format. + +`go-multierror` implements the +[errwrap](https://github.com/hashicorp/errwrap) interface so that it can +be used with that library, as well. + +## Installation and Docs + +Install using `go get github.com/hashicorp/go-multierror`. + +Full documentation is available at +http://godoc.org/github.com/hashicorp/go-multierror + +## Usage + +go-multierror is easy to use and purposely built to be unobtrusive in +existing Go applications/libraries that may not be aware of it. + +**Building a list of errors** + +The `Append` function is used to create a list of errors.

But if you're aware a multierror might +be returned, you can use type switches to access the list of errors: + +```go +if err := something(); err != nil { + if merr, ok := err.(*multierror.Error); ok { + // Use merr.Errors + } +} +``` + +**Returning a multierror only if there are errors** + +If you build a `multierror.Error`, you can use the `ErrorOrNil` function +to return an `error` implementation only if there are errors to return: + +```go +var result *multierror.Error + +// ... accumulate errors here + +// Return the `error` only if errors were added to the multierror, otherwise +// return nil since there are no errors. +return result.ErrorOrNil() +``` diff --git a/vendor/github.com/hashicorp/go-multierror/append.go b/vendor/github.com/hashicorp/go-multierror/append.go new file mode 100644 index 000000000000..775b6e753e77 --- /dev/null +++ b/vendor/github.com/hashicorp/go-multierror/append.go @@ -0,0 +1,41 @@ +package multierror + +// Append is a helper function that will append more errors +// onto an Error in order to create a larger multi-error. +// +// If err is not a multierror.Error, then it will be turned into +// one.
