Add support for GO Modules

This removes vndr, and swiches to native Go Modules instead. All modules
are kept on the old version.

Keeps the vendor/ dir, so everything is backwards compatible.

## go-criu -- Go bindings for [CRIU](https://criu.org/)
This repository provides Go bindings for CRIU. The code is based on the Go based PHaul
implementation from the CRIU repository. For easier inclusion into other Go projects the
CRIU Go bindings have been moved to this repository.
The Go bindings provide an easy way to use the CRIU RPC calls from Go without the need
to set up all the infrastructure to make the actual RPC connection to CRIU.
The following example would print the version of CRIU:
```
c := criu.MakeCriu()
version, err := c.GetCriuVersion()
fmt.Println(version)
```
or to just check if at least a certain CRIU version is installed:
```
c := criu.MakeCriu()
result, err := c.IsCriuAtLeast(31100)
```
## How to contribute
While bug fixes can first be identified via an "issue", that is not required.
It's ok to just open up a PR with the fix, but make sure you include the same
information you would have included in an issue - like how to reproduce it.
PRs for new features should include some background on what use cases the
new code is trying to address. When possible and when it makes sense, try to
break-up larger PRs into smaller ones - it's easier to review smaller
code changes. But only if those smaller ones make sense as stand-alone PRs.
Regardless of the type of PR, all PRs should include:
* well documented code changes
* additional testcases. Ideally, they should fail w/o your code change applied
* documentation changes
Squash your commits into logical pieces of work that might want to be reviewed
separate from the rest of the PRs. Ideally, each commit should implement a
single idea, and the PR branch should pass the tests at every commit. GitHub
makes it easy to review the cumulative effect of many commits; so, when in
doubt, use smaller commits.
PRs that fix issues should include a reference like `Closes #XXXX` in the
commit message so that github will automatically close the referenced issue
when the PR is merged.
Contributors must assert that they are in compliance with the [Developer
Certificate of Origin 1.1](http://developercertificate.org/). This is achieved
by adding a "Signed-off-by" line containing the contributor's name and e-mail
to every commit message. Your signature certifies that you wrote the patch or
otherwise have the right to pass it on as an open-source patch.
### License
The license of go-criu is the Apache 2.0 license.

# go-systemd
[![Build Status](https://travis-ci.org/coreos/go-systemd.png?branch=master)](https://travis-ci.org/coreos/go-systemd)
[![godoc](https://godoc.org/github.com/coreos/go-systemd?status.svg)](http://godoc.org/github.com/coreos/go-systemd)
![minimum golang 1.10](https://img.shields.io/badge/golang-1.10%2B-orange.svg)
Go bindings to systemd. The project has several packages:
- `activation` - for writing and using socket activation from Go
- `daemon` - for notifying systemd of service status changes
- `dbus` - for starting/stopping/inspecting running services and units
- `journal` - for writing to systemd's logging service, journald
- `sdjournal` - for reading from journald by wrapping its C API
- `login1` - for integration with the systemd logind API
- `machine1` - for registering machines/containers with systemd
- `unit` - for (de)serialization and comparison of unit files
## Socket Activation
An example HTTP server using socket activation can be quickly set up by following this README on a Linux machine running systemd:
https://github.com/coreos/go-systemd/tree/master/examples/activation/httpserver
## systemd Service Notification
The `daemon` package is an implementation of the [sd_notify protocol](https://www.freedesktop.org/software/systemd/man/sd_notify.html#Description). It can be used to inform systemd of service start-up completion, watchdog events, and other status changes.
## D-Bus
The `dbus` package connects to the [systemd D-Bus API](http://www.freedesktop.org/wiki/Software/systemd/dbus/) and lets you start, stop and introspect systemd units. The API docs are here:
http://godoc.org/github.com/coreos/go-systemd/dbus
### Debugging
Create `/etc/dbus-1/system-local.conf` that looks like this:
```
<!DOCTYPE busconfig PUBLIC
"-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN"
"http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>
<policy user="root">
<allow eavesdrop="true"/>
<allow eavesdrop="true" send_destination="*"/>
</policy>
</busconfig>
```
## Journal
### Writing to the Journal
Using the pure-Go `journal` package you can submit journal entries directly to systemd's journal, taking advantage of features like indexed key/value pairs for each log entry.
### Reading from the Journal
The `sdjournal` package provides read access to the journal by wrapping around journald's native C API; consequently it requires cgo and the journal headers to be available.
## logind
The `login1` package provides functions to integrate with the [systemd logind API](http://www.freedesktop.org/wiki/Software/systemd/logind/).
## machined
The `machine1` package allows interaction with the [systemd machined D-Bus API](http://www.freedesktop.org/wiki/Software/systemd/machined/).
## Units
The `unit` package provides various functions for working with [systemd unit files](http://www.freedesktop.org/software/systemd/man/systemd.unit.html).

# Contributing to go-units
Want to hack on go-units? Awesome! Here are instructions to get you started.
go-units is a part of the [Docker](https://www.docker.com) project, and follows
the same rules and principles. If you're already familiar with the way
Docker does things, you'll feel right at home.
Otherwise, go read Docker's
[contributions guidelines](https://github.com/docker/docker/blob/master/CONTRIBUTING.md),
[issue triaging](https://github.com/docker/docker/blob/master/project/ISSUE-TRIAGE.md),
[review process](https://github.com/docker/docker/blob/master/project/REVIEWING.md) and
[branches and tags](https://github.com/docker/docker/blob/master/project/BRANCHES-AND-TAGS.md).
### Sign your work
The sign-off is a simple line at the end of the explanation for the patch. Your
signature certifies that you wrote the patch or otherwise have the right to pass
it on as an open-source patch. The rules are pretty simple: if you can certify
the below (from [developercertificate.org](http://developercertificate.org/)):
```
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
```
Then you just add a line to every git commit message:
Signed-off-by: Joe Smith <joe.smith@email.com>
Use your real name (sorry, no pseudonyms or anonymous contributions.)
If you set your `user.name` and `user.email` git configs, you can sign your
commit automatically with `git commit -s`.

# How to Contribute
## Getting Started
- Fork the repository on GitHub
- Read the [README](README.markdown) for build and test instructions
- Play with the project, submit bugs, submit patches!
## Contribution Flow
This is a rough outline of what a contributor's workflow looks like:
- Create a topic branch from where you want to base your work (usually master).
- Make commits of logical units.
- Make sure your commit messages are in the proper format (see below).
- Push your changes to a topic branch in your fork of the repository.
- Make sure the tests pass, and add any new tests as appropriate.
- Submit a pull request to the original repository.
Thanks for your contributions!
### Format of the Commit Message
We follow a rough convention for commit messages that is designed to answer two
questions: what changed and why. The subject line should feature the what and
the body of the commit should describe the why.
```
scripts: add the test-cluster command
this uses tmux to setup a test cluster that you can easily kill and
start for debugging.
Fixes #38
```
The format can be described more formally as follows:
```
<subsystem>: <what changed>
<BLANK LINE>
<why this change was made>
<BLANK LINE>
<footer>
```
The first line is the subject and should be no longer than 70 characters, the
second line is always blank, and other lines should be wrapped at 80 characters.
This allows the message to be easier to read on GitHub as well as in various
git tools.

# Go support for Protocol Buffers
[![Build Status](https://travis-ci.org/golang/protobuf.svg?branch=master)](https://travis-ci.org/golang/protobuf)
[![GoDoc](https://godoc.org/github.com/golang/protobuf?status.svg)](https://godoc.org/github.com/golang/protobuf)
Google's data interchange format.
Copyright 2010 The Go Authors.
https://github.com/golang/protobuf
This package and the code it generates requires at least Go 1.4.
This software implements Go bindings for protocol buffers. For
information about protocol buffers themselves, see
https://developers.google.com/protocol-buffers/
## Installation ##
To use this software, you must:
- Install the standard C++ implementation of protocol buffers from
https://developers.google.com/protocol-buffers/
- Of course, install the Go compiler and tools from
https://golang.org/
See
https://golang.org/doc/install
for details or, if you are using gccgo, follow the instructions at
https://golang.org/doc/install/gccgo
- Grab the code from the repository and install the proto package.
The simplest way is to run `go get -u github.com/golang/protobuf/protoc-gen-go`.
The compiler plugin, protoc-gen-go, will be installed in $GOBIN,
defaulting to $GOPATH/bin. It must be in your $PATH for the protocol
compiler, protoc, to find it.
This software has two parts: a 'protocol compiler plugin' that
generates Go source files that, once compiled, can access and manage
protocol buffers; and a library that implements run-time support for
encoding (marshaling), decoding (unmarshaling), and accessing protocol
buffers.
There is support for gRPC in Go using protocol buffers.
See the note at the bottom of this file for details.
There are no insertion points in the plugin.
## Using protocol buffers with Go ##
Once the software is installed, there are two steps to using it.
First you must compile the protocol buffer definitions and then import
them, with the support library, into your program.
To compile the protocol buffer definition, run protoc with the --go_out
parameter set to the directory you want to output the Go code to.
protoc --go_out=. *.proto
The generated files will be suffixed .pb.go. See the Test code below
for an example using such a file.
The package comment for the proto library contains text describing
the interface provided in Go for protocol buffers. Here is an edited
version.
==========
The proto package converts data structures to and from the
wire format of protocol buffers. It works in concert with the
Go source code generated for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
Helpers for getting values are superseded by the
GetFoo methods and their use is deprecated.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed with the enum's type name. Enum types have
a String method, and a Enum method to assist in message construction.
- Nested groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Enum types do not get an Enum method.
Consider file test.proto, containing
```proto
syntax = "proto2";
package example;
enum FOO { X = 17; };
message Test {
required string label = 1;
optional int32 type = 2 [default=77];
repeated int64 reps = 3;
optional group OptionalGroup = 4 {
required string RequiredField = 5;
}
}
```
To create and play with a Test object from the example package,
```go
package main
import (
"log"
"github.com/golang/protobuf/proto"
"path/to/example"
)
func main() {
test := &example.Test {
Label: proto.String("hello"),
Type: proto.Int32(17),
Reps: []int64{1, 2, 3},
Optionalgroup: &example.Test_OptionalGroup {
RequiredField: proto.String("good bye"),
},
}
data, err := proto.Marshal(test)
if err != nil {
log.Fatal("marshaling error: ", err)
}
newTest := &example.Test{}
err = proto.Unmarshal(data, newTest)
if err != nil {
log.Fatal("unmarshaling error: ", err)
}
// Now test and newTest contain the same data.
if test.GetLabel() != newTest.GetLabel() {
log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel())
}
// etc.
}
```
## Parameters ##
To pass extra parameters to the plugin, use a comma-separated
parameter list separated from the output directory by a colon:
protoc --go_out=plugins=grpc,import_path=mypackage:. *.proto
- `import_prefix=xxx` - a prefix that is added onto the beginning of
all imports. Useful for things like generating protos in a
subdirectory, or regenerating vendored protobufs in-place.
- `import_path=foo/bar` - used as the package if no input files
declare `go_package`. If it contains slashes, everything up to the
rightmost slash is ignored.
- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to
load. The only plugin in this repo is `grpc`.
- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is
associated with Go package quux/shme. This is subject to the
import_prefix parameter.
## gRPC Support ##
If a proto file specifies RPC services, protoc-gen-go can be instructed to
generate code compatible with gRPC (http://www.grpc.io/). To do this, pass
the `plugins` parameter to protoc-gen-go; the usual way is to insert it into
the --go_out argument to protoc:
protoc --go_out=plugins=grpc:. *.proto
## Compatibility ##
The library and the generated code are expected to be stable over time.
However, we reserve the right to make breaking changes without notice for the
following reasons:
- Security. A security issue in the specification or implementation may come to
light whose resolution requires breaking compatibility. We reserve the right
to address such security issues.
- Unspecified behavior. There are some aspects of the Protocol Buffers
specification that are undefined. Programs that depend on such unspecified
behavior may break in future releases.
- Specification errors or changes. If it becomes necessary to address an
inconsistency, incompleteness, or change in the Protocol Buffers
specification, resolving the issue could affect the meaning or legality of
existing programs. We reserve the right to address such issues, including
updating the implementations.
- Bugs. If the library has a bug that violates the specification, a program
that depends on the buggy behavior may break if the bug is fixed. We reserve
the right to fix such bugs.
- Adding methods or fields to generated structs. These may conflict with field
names that already exist in a schema, causing applications to break. When the
code generator encounters a field in the schema that would collide with a
generated field or method name, the code generator will append an underscore
to the generated field or method name.
- Adding, removing, or changing methods or fields in generated structs that
start with `XXX`. These parts of the generated code are exported out of
necessity, but should not be considered part of the public API.
- Adding, removing, or changing unexported symbols in generated code.
Any breaking changes outside of these will be announced 6 months in advance to
protobuf@googlegroups.com.
You should, whenever possible, use generated code created by the `protoc-gen-go`
tool built at the same commit as the `proto` package. The `proto` package
declares package-level constants in the form `ProtoPackageIsVersionX`.
Application code and generated code may depend on one of these constants to
ensure that compilation will fail if the available version of the proto library
is too old. Whenever we make a change to the generated code that requires newer
library support, in the same commit we will increment the version number of the
generated code and declare a new package-level constant whose name incorporates
the latest version number. Removing a compatibility constant is considered a
breaking change and would be subject to the announcement policy stated above.
The `protoc-gen-go/generator` package exposes a plugin interface,
which is used by the gRPC code generation. This interface is not
supported and is subject to incompatible changes without notice.

# Open Container Initiative Runtime Specification
The [Open Container Initiative][oci] develops specifications for standards on Operating System process and application containers.
The specification can be found [here](spec.md).
## Table of Contents
Additional documentation about how this group operates:
- [Code of Conduct][code-of-conduct]
- [Style and Conventions](style.md)
- [Implementations](implementations.md)
- [Releases](RELEASES.md)
- [project](project.md)
- [charter][charter]
## Use Cases
To provide context for users the following section gives example use cases for each part of the spec.
### Application Bundle Builders
Application bundle builders can create a [bundle](bundle.md) directory that includes all of the files required for launching an application as a container.
The bundle contains an OCI [configuration file](config.md) where the builder can specify host-independent details such as [which executable to launch](config.md#process) and host-specific settings such as [mount](config.md#mounts) locations, [hook](config.md#posix-platform-hooks) paths, Linux [namespaces](config-linux.md#namespaces) and [cgroups](config-linux.md#control-groups).
Because the configuration includes host-specific settings, application bundle directories copied between two hosts may require configuration adjustments.
### Hook Developers
[Hook](config.md#posix-platform-hooks) developers can extend the functionality of an OCI-compliant runtime by hooking into a container's lifecycle with an external application.
Example use cases include sophisticated network configuration, volume garbage collection, etc.
### Runtime Developers
Runtime developers can build runtime implementations that run OCI-compliant bundles and container configuration, containing low-level OS and host-specific details, on a particular platform.
## Contributing
Development happens on GitHub for the spec.
Issues are used for bugs and actionable items and longer discussions can happen on the [mailing list](#mailing-list).
The specification and code is licensed under the Apache 2.0 license found in the [LICENSE](./LICENSE) file.
### Discuss your design
The project welcomes submissions, but please let everyone know what you are working on.
Before undertaking a nontrivial change to this specification, send mail to the [mailing list](#mailing-list) to discuss what you plan to do.
This gives everyone a chance to validate the design, helps prevent duplication of effort, and ensures that the idea fits.
It also guarantees that the design is sound before code is written; a GitHub pull-request is not the place for high-level discussions.
Typos and grammatical errors can go straight to a pull-request.
When in doubt, start on the [mailing-list](#mailing-list).
### Meetings
The contributors and maintainers of all OCI projects have monthly meetings, which are usually at 2:00 PM (USA Pacific) on the first Wednesday of every month.
There is an [iCalendar][rfc5545] format for the meetings [here](meeting.ics).
Everyone is welcome to participate via [UberConference web][uberconference] or audio-only: +1 415 968 0849 (no PIN needed).
An initial agenda will be posted to the [mailing list](#mailing-list) in the week before each meeting, and everyone is welcome to propose additional topics or suggest other agenda alterations there.
Minutes are posted to the [mailing list](#mailing-list) and minutes from past calls are archived [here][minutes], with minutes from especially old meetings (September 2015 and earlier) archived [here][runtime-wiki].
### Mailing List
You can subscribe and join the mailing list on [Google Groups][dev-list].
### IRC
OCI discussion happens on #opencontainers on Freenode ([logs][irc-logs]).
### Git commit
#### Sign your work
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch.
The rules are pretty simple: if you can certify the below (from http://developercertificate.org):
```
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
```
then you just add a line to every git commit message:
Signed-off-by: Joe Smith <joe@gmail.com>
using your real name (sorry, no pseudonyms or anonymous contributions.)
You can add the sign off when creating the git commit via `git commit -s`.
#### Commit Style
Simple house-keeping for clean git history.
Read more on [How to Write a Git Commit Message][how-to-git-commit] or the Discussion section of [git-commit(1)][git-commit.1].
1. Separate the subject from body with a blank line
2. Limit the subject line to 50 characters
3. Capitalize the subject line
4. Do not end the subject line with a period
5. Use the imperative mood in the subject line
6. Wrap the body at 72 characters
7. Use the body to explain what and why vs. how
* If there was important/useful/essential conversation or information, copy or include a reference
8. When possible, one keyword to scope the change in the subject (i.e. "README: ...", "runtime: ...")

How to Submit Patches to the libseccomp Project
===============================================================================
https://github.com/seccomp/libseccomp-golang
This document is intended to act as a guide to help you contribute to the
libseccomp project. It is not perfect, and there will always be exceptions
to the rules described here, but by following the instructions below you
should have a much easier time getting your work merged with the upstream
project.
* Test Your Code
There are two possible tests you can run to verify your code. The first test
is used to check the formatting and coding style of your changes, you can run
the test with the following command:
# make check-syntax
... if there are any problems with your changes a diff/patch will be shown
which indicates the problems and how to fix them.
The second possible test is used to ensure the sanity of your code changes
and to test these changes against the included tests. You can run the test
with the following command:
# make check
... if there are any faults or errors they will be displayed.
* Generate the Patch(es)
Depending on how you decided to work with the libseccomp code base and what
tools you are using there are different ways to generate your patch(es).
However, regardless of what tools you use, you should always generate your
patches using the "unified" diff/patch format and the patches should always
apply to the libseccomp source tree using the following command from the top
directory of the libseccomp sources:
# patch -p1 < changes.patch
If you are not using git, stacked git (stgit), or some other tool which can
generate patch files for you automatically, you may find the following command
helpful in generating patches, where "libseccomp.orig/" is the unmodified
source code directory and "libseccomp/" is the source code directory with your
changes:
# diff -purN libseccomp-golang.orig/ libseccomp-golang/
When in doubt please generate your patch and try applying it to an unmodified
copy of the libseccomp sources; if it fails for you, it will fail for the rest
of us.
* Explain Your Work
At the top of every patch you should include a description of the problem you
are trying to solve, how you solved it, and why you chose the solution you
implemented. If you are submitting a bug fix, it is also incredibly helpful
if you can describe/include a reproducer for the problem in the description as
well as instructions on how to test for the bug and verify that it has been
fixed.
* Sign Your Work
The sign-off is a simple line at the end of the patch description, which
certifies that you wrote it or otherwise have the right to pass it on as an
open-source patch. The "Developer's Certificate of Origin" pledge is taken
from the Linux Kernel and the rules are pretty simple:
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
... then you just add a line to the bottom of your patch description, with
your real name, saying:
Signed-off-by: Random J Developer <random@developer.example.org>
* Email Your Patch(es)
Finally, you will need to email your patches to the mailing list so they can
be reviewed and potentially merged into the main libseccomp-golang repository.
When sending patches to the mailing list it is important to send your email in
text form, no HTML mail please, and ensure that your email client does not
mangle your patches. It should be possible to save your raw email to disk and
apply it directly to the libseccomp source code; if that fails then you likely
have a problem with your email client. When in doubt try a test first by
sending yourself an email with your patch and attempting to apply the emailed
patch to the libseccomp-golang repository; if it fails for you, it will fail
for the rest of us trying to test your patch and include it in the main
libseccomp-golang repository.

# Change Log
**ATTN**: This project uses [semantic versioning](http://semver.org/).
## [Unreleased]
## 1.20.0 - 2017-08-10
### Fixed
* `HandleExitCoder` is now correctly iterates over all errors in
a `MultiError`. The exit code is the exit code of the last error or `1` if
there are no `ExitCoder`s in the `MultiError`.
* Fixed YAML file loading on Windows (previously would fail validate the file path)
* Subcommand `Usage`, `Description`, `ArgsUsage`, `OnUsageError` correctly
propogated
* `ErrWriter` is now passed downwards through command structure to avoid the
need to redefine it
* Pass `Command` context into `OnUsageError` rather than parent context so that
all fields are avaiable
* Errors occuring in `Before` funcs are no longer double printed
* Use `UsageText` in the help templates for commands and subcommands if
defined; otherwise build the usage as before (was previously ignoring this
field)
* `IsSet` and `GlobalIsSet` now correctly return whether a flag is set if
a program calls `Set` or `GlobalSet` directly after flag parsing (would
previously only return `true` if the flag was set during parsing)
### Changed
* No longer exit the program on command/subcommand error if the error raised is
not an `OsExiter`. This exiting behavior was introduced in 1.19.0, but was
determined to be a regression in functionality. See [the
PR](https://github.com/urfave/cli/pull/595) for discussion.
### Added
* `CommandsByName` type was added to make it easy to sort `Command`s by name,
alphabetically
* `altsrc` now handles loading of string and int arrays from TOML
* Support for definition of custom help templates for `App` via
`CustomAppHelpTemplate`
* Support for arbitrary key/value fields on `App` to be used with
`CustomAppHelpTemplate` via `ExtraInfo`
* `HelpFlag`, `VersionFlag`, and `BashCompletionFlag` changed to explictly be
`cli.Flag`s allowing for the use of custom flags satisfying the `cli.Flag`
interface to be used.
## [1.19.1] - 2016-11-21
### Fixed
- Fixes regression introduced in 1.19.0 where using an `ActionFunc` as
the `Action` for a command would cause it to error rather than calling the
function. Should not have a affected declarative cases using `func(c
*cli.Context) err)`.
- Shell completion now handles the case where the user specifies
`--generate-bash-completion` immediately after a flag that takes an argument.
Previously it call the application with `--generate-bash-completion` as the
flag value.
## [1.19.0] - 2016-11-19
### Added
- `FlagsByName` was added to make it easy to sort flags (e.g. `sort.Sort(cli.FlagsByName(app.Flags))`)
- A `Description` field was added to `App` for a more detailed description of
the application (similar to the existing `Description` field on `Command`)
- Flag type code generation via `go generate`
- Write to stderr and exit 1 if action returns non-nil error
- Added support for TOML to the `altsrc` loader
- `SkipArgReorder` was added to allow users to skip the argument reordering.
This is useful if you want to consider all "flags" after an argument as
arguments rather than flags (the default behavior of the stdlib `flag`
library). This is backported functionality from the [removal of the flag
reordering](https://github.com/urfave/cli/pull/398) in the unreleased version
2
- For formatted errors (those implementing `ErrorFormatter`), the errors will
be formatted during output. Compatible with `pkg/errors`.
### Changed
- Raise minimum tested/supported Go version to 1.2+
### Fixed
- Consider empty environment variables as set (previously environment variables
with the equivalent of `""` would be skipped rather than their value used).
- Return an error if the value in a given environment variable cannot be parsed
as the flag type. Previously these errors were silently swallowed.
- Print full error when an invalid flag is specified (which includes the invalid flag)
- `App.Writer` defaults to `stdout` when `nil`
- If no action is specified on a command or app, the help is now printed instead of `panic`ing
- `App.Metadata` is initialized automatically now (previously was `nil` unless initialized)
- Correctly show help message if `-h` is provided to a subcommand
- `context.(Global)IsSet` now respects environment variables. Previously it
would return `false` if a flag was specified in the environment rather than
as an argument
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
- `altsrc`s import paths were updated to use `gopkg.in/urfave/cli.v1`. This
fixes issues that occurred when `gopkg.in/urfave/cli.v1` was imported as well
as `altsrc` where Go would complain that the types didn't match
## [1.18.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
## [1.18.0] - 2016-06-27
### Added
- `./runtests` test runner with coverage tracking by default
- testing on OS X
- testing on Windows
- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
### Changed
- Use spaces for alignment in help/usage output instead of tabs, making the
output alignment consistent regardless of tab width
### Fixed
- Printing of command aliases in help text
- Printing of visible flags for both struct and struct pointer flags
- Display the `help` subcommand when using `CommandCategories`
- No longer swallows `panic`s that occur within the `Action`s themselves when
detecting the signature of the `Action` field
## [1.17.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [1.17.0] - 2016-05-09
### Added
- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
- Support for hiding commands by setting `Hidden: true` -- this will hide the
commands in help output
### Changed
- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
quoted in help text output.
- All flag types now include `(default: {value})` strings following usage when a
default value can be (reasonably) detected.
- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
with non-slice flag types
- Apps now exit with a code of 3 if an unknown subcommand is specified
(previously they printed "No help topic for...", but still exited 0. This
makes it easier to script around apps built using `cli` since they can trust
that a 0 exit code indicated a successful execution.
- cleanups based on [Go Report Card
feedback](https://goreportcard.com/report/github.com/urfave/cli)
## [1.16.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [1.16.0] - 2016-05-02
### Added
- `Hidden` field on all flag struct types to omit from generated help text
### Changed
- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
generated help text via the `Hidden` field
### Fixed
- handling of error values in `HandleAction` and `HandleExitCoder`
## [1.15.0] - 2016-04-30
### Added
- This file!
- Support for placeholders in flag usage strings
- `App.Metadata` map for arbitrary data/state management
- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
parsing.
- Support for nested lookup of dot-delimited keys in structures loaded from
YAML.
### Changed
- The `App.Action` and `Command.Action` now prefer a return signature of
`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
`error` is returned, there may be two outcomes:
- If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
automatically
- Else the error is bubbled up and returned from `App.Run`
- Specifying an `Action` with the legacy return signature of
`func(*cli.Context)` will produce a deprecation message to stderr
- Specifying an `Action` that is not a `func` type will produce a non-zero exit
from `App.Run`
- Specifying an `Action` func that has an invalid (input) signature will
produce a non-zero exit from `App.Run`
### Deprecated
- <a name="deprecated-cli-app-runandexitonerror"></a>
`cli.App.RunAndExitOnError`, which should now be done by returning an error
that fulfills `cli.ExitCoder` to `cli.App.Run`.
- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
`cli.App.Action` of `func(*cli.Context)`, which should now have a return
signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
### Fixed
- Added missing `*cli.Context.GlobalFloat64` method
## [1.14.0] - 2016-04-03 (backfilled 2016-04-25)
### Added
- Codebeat badge
- Support for categorization via `CategorizedHelp` and `Categories` on app.
### Changed
- Use `filepath.Base` instead of `path.Base` in `Name` and `HelpName`.
### Fixed
- Ensure version is not shown in help text when `HideVersion` set.

"""
The flag types that ship with the cli library have many things in common, and
so we can take advantage of the `go generate` command to create much of the
source code from a list of definitions. These definitions attempt to cover
the parts that vary between flag types, and should evolve as needed.
An example of the minimum definition needed is:
{
"name": "SomeType",
"type": "sometype",
"context_default": "nil"
}
In this example, the code generated for the `cli` package will include a type
named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
Fetching values by name via `*cli.Context` will default to a value of `nil`.
A more complete, albeit somewhat redundant, example showing all available
definition keys is:
{
"name": "VeryMuchType",
"type": "*VeryMuchType",
"value": true,
"dest": false,
"doctail": " which really only wraps a []float64, oh well!",
"context_type": "[]float64",
"context_default": "nil",
"parser": "parseVeryMuchType(f.Value.String())",
"parser_cast": "[]float64(parsed)"
}
The meaning of each field is as follows:
name (string) - The type "name", which will be suffixed with
`Flag` when generating the type definition
for `cli` and the wrapper type for `altsrc`
type (string) - The type that the generated `Flag` type for `cli`
is expected to "contain" as its `.Value` member
value (bool) - Should the generated `cli` type have a `Value`
member?
dest (bool) - Should the generated `cli` type support a
destination pointer?
doctail (string) - Additional docs for the `cli` flag type comment
context_type (string) - The literal type used in the `*cli.Context`
reader func signature
context_default (string) - The literal value used as the default by the
`*cli.Context` reader funcs when no value is
present
parser (string) - Literal code used to parse the flag `f`,
expected to have a return signature of
(value, error)
parser_cast (string) - Literal code used to cast the `parsed` value
returned from the `parser` code
