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 0000000..a733bef --- /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` is fully compatible with the Go standard library +[errors](https://golang.org/pkg/errors/) package, including the +functions `As`, `Is`, and `Unwrap`. This provides a standardized approach +for introspecting on error values. + +## Installation and Docs + +Install using `go get github.com/hashicorp/go-multierror`. + +Full documentation is available at +https://pkg.go.dev/github.com/hashicorp/go-multierror + +### Requires go version 1.13 or newer + +`go-multierror` requires go version 1.13 or newer. Go 1.13 introduced +[error wrapping](https://golang.org/doc/go1.13#error_wrapping), which +this library takes advantage of. + +If you need to use an earlier version of go, you can use the +[v1.0.0](https://github.com/hashicorp/go-multierror/tree/v1.0.0) +tag, which doesn't rely on features in go 1.13. + +If you see compile errors that look like the below, it's likely that +you're on an older version of go: + +``` +/go/src/github.com/hashicorp/go-multierror/multierror.go:112:9: undefined: errors.As +/go/src/github.com/hashicorp/go-multierror/multierror.go:117:9: undefined: errors.Is +``` + +## 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. This function +behaves a lot like the Go built-in `append` function: it doesn't matter +if the first argument is nil, a `multierror.Error`, or any other `error`, +the function behaves as you would expect. + +```go +var result error + +if err := step1(); err != nil { + result = multierror.Append(result, err) +} +if err := step2(); err != nil { + result = multierror.Append(result, err) +} + +return result +``` + +**Customizing the formatting of the errors** + +By specifying a custom `ErrorFormat`, you can customize the format +of the `Error() string` function: + +```go +var result *multierror.Error + +// ... accumulate errors here, maybe using Append + +if result != nil { + result.ErrorFormat = func([]error) string { + return "errors!" + } +} +``` + +**Accessing the list of errors** + +`multierror.Error` implements `error` so if the caller doesn't know about +multierror, it will work just fine. 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 + } +} +``` + +You can also use the standard [`errors.Unwrap`](https://golang.org/pkg/errors/#Unwrap) +function. This will continue to unwrap into subsequent errors until none exist. + +**Extracting an error** + +The standard library [`errors.As`](https://golang.org/pkg/errors/#As) +function can be used directly with a multierror to extract a specific error: + +```go +// Assume err is a multierror value +err := somefunc() + +// We want to know if "err" has a "RichErrorType" in it and extract it. +var errRich RichErrorType +if errors.As(err, &errRich) { + // It has it, and now errRich is populated. +} +``` + +**Checking for an exact error value** + +Some errors are returned as exact errors such as the [`ErrNotExist`](https://golang.org/pkg/os/#pkg-variables) +error in the `os` package. You can check if this error is present by using +the standard [`errors.Is`](https://golang.org/pkg/errors/#Is) function. + +```go +// Assume err is a multierror value +err := somefunc() +if errors.Is(err, os.ErrNotExist) { + // err contains os.ErrNotExist +} +``` + +**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 0000000..3e2589b --- /dev/null +++ b/vendor/github.com/hashicorp/go-multierror/append.go @@ -0,0 +1,43 @@ +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.

See: https://godoc.org/golang.org/x/sys/unix + +Porting Go to a new architecture/OS combination or adding syscalls, types, or +constants to an existing architecture/OS pair requires some manual effort; +however, there are tools that automate much of the process. + +## Build Systems + +There are currently two ways we generate the necessary files. We are currently +migrating the build system to use containers so the builds are reproducible. +This is being done on an OS-by-OS basis. Please update this documentation as +components of the build system change. + +### Old Build System (currently for `GOOS != "linux"`) + +The old build system generates the Go files based on the C header files +present on your system. This means that files +for a given GOOS/GOARCH pair must be generated on a system with that OS and +architecture. This also means that the generated code can differ from system +to system, based on differences in the header files. + +To avoid this, if you are using the old build system, only generate the Go +files on an installation with unmodified header files. It is also important to +keep track of which version of the OS the files were generated from (ex. +Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes +and have each OS upgrade correspond to a single change. + +To build the files for your current OS and architecture, make sure GOOS and +GOARCH are set correctly and run `mkall.sh`. This will generate the files for +your specific system. Running `mkall.sh -n` shows the commands that will be run. + +Requirements: bash, go + +### New Build System (currently for `GOOS == "linux"`) + +The new build system uses a Docker container to generate the go files directly +from source checkouts of the kernel and various system libraries. This means +that on any platform that supports Docker, all the files using the new build +system can be generated at once, and generated files will not change based on +what the person running the scripts has installed on their computer. + +The OS specific files for the new build system are located in the `${GOOS}` +directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When +the kernel or system library updates, modify the Dockerfile at +`${GOOS}/Dockerfile` to checkout the new release of the source. + +To build all the files under the new build system, you must be on an amd64/Linux +system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will +then generate all of the files for all of the GOOS/GOARCH pairs in the new build +system. Running `mkall.sh -n` shows the commands that will be run. + +Requirements: bash, go, docker + +## Component files + +This section describes the various files used in the code generation process. +It also contains instructions on how to modify these files to add a new +architecture/OS or to add additional syscalls, types, or constants. Note that +if you are using the new build system, the scripts/programs cannot be called normally. +They must be called from within the docker container. + +### asm files + +The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system +call dispatch. There are three entry points: +``` + func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr) + func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr) + func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr) +``` +The first and second are the standard ones; they differ only in how many +arguments can be passed to the kernel. The third is for low-level use by the +ForkExec wrapper. Unlike the first two, it does not call into the scheduler to +let it know that a system call is running. + +When porting Go to a new architecture/OS, this file must be implemented for +each GOOS/GOARCH pair. + +### mksysnum + +Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go` +for the old system). This program takes in a list of header files containing the +syscall number declarations and parses them to produce the corresponding list of +Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated +constants. + +Adding new syscall numbers is mostly done by running the build on a sufficiently +new installation of the target OS (or updating the source checkouts for the +new build system). However, depending on the OS, you may need to update the +parsing in mksysnum. + +### mksyscall.go + +The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are +hand-written Go files which implement system calls (for unix, the specific OS, +or the specific OS/Architecture pair respectively) that need special handling +and list `//sys` comments giving prototypes for ones that can be generated. + +The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts +them into syscalls. This requires the name of the prototype in the comment to +match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function +prototype can be exported (capitalized) or not. + +Adding a new syscall often just requires adding a new `//sys` function prototype +with the desired arguments and a capitalized name so it is exported. However, if +you want the interface to the syscall to be different, often one will make an +unexported `//sys` prototype, and then write a custom wrapper in +`syscall_${GOOS}.go`. + +### types files + +For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or +`types_${GOOS}.go` on the old system). This file includes standard C headers and +creates Go type aliases to the corresponding C types. The file is then fed +through godef to get the Go compatible definitions. Finally, the generated code +is fed though mkpost.go to format the code correctly and remove any hidden or +private identifiers. This cleaned-up code is written to +`ztypes_${GOOS}_${GOARCH}.go`. + +The hardest part about preparing this file is figuring out which headers to +include and which symbols need to be `#define`d to get the actual data +structures that pass through to the kernel system calls. Some C libraries +preset alternate versions for binary compatibility and translate them on the +way in and out of system calls, but there is almost always a `#define` that can +get the real ones. +See `types_darwin.go` and `linux/types.go` for examples. + +To add a new type, add in the necessary include statement at the top of the +file (if it is not already there) and add in a type alias line. Note that if +your type is significantly different on different architectures, you may need +some `#if/#elif` macros in your include statements. + +### mkerrors.sh + +This script is used to generate the system's various constants. This doesn't +just include the error numbers and error strings, but also the signal numbers +and a wide variety of miscellaneous constants. The constants come from the list +of include files in the `includes_${uname}` variable. A regex then picks out +the desired `#define` statements, and generates the corresponding Go constants. +The error numbers and strings are generated from `#include `, and the +signal numbers and strings are generated from `#include `. All of +these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program, +`_errors.c`, which prints out all the constants. + +To add a constant, add the header that includes it to the appropriate variable. +Then, edit the regex (if necessary) to match the desired constant. Avoid making +the regex too broad to avoid matching unintended constants. + +### internal/mkmerge + +This program is used to extract duplicate const, func, and type declarations +from the generated architecture-specific files listed below, and merge these +into a common file for each OS. + +The merge is performed in the following steps: +1. Construct the set of common code that is idential in all architecture-specific files. +2. Write this common code to the merged file. +3. Remove the common code from all architecture-specific files. + + +## Generated files + +### `zerrors_${GOOS}_${GOARCH}.go` + +A file containing all of the system's generated error numbers, error strings, +signal numbers, and constants. Generated by `mkerrors.sh` (see above). + +### `zsyscall_${GOOS}_${GOARCH}.go` + +A file containing all the generated syscalls for a specific GOOS and GOARCH. +Generated by `mksyscall.go` (see above). + +### `zsysnum_${GOOS}_${GOARCH}.go` + +A list of numeric constants for all the syscall number of the specific GOOS +and GOARCH.
