/*
Package antlr implements the Go version of the ANTLR 4 runtime.
# The ANTLR Tool
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing,
or translating structured text or binary files. It's widely used to build languages, tools, and frameworks.
From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface
(or visitor) that makes it easy to respond to the recognition of phrases of interest.
# Code Generation
ANTLR supports the generation of code in a number of [target languages], and the generated code is supported by a
runtime library, written specifically to support the generated code in the target language. This library is the
runtime for the Go target.
To generate code for the go target, it is generally recommended to place the source grammar files in a package of
their own, and use the `.sh` script method of generating code, using the go generate directive. In that same directory
it is usual, though not required, to place the antlr tool that should be used to generate the code. That does mean
that the antlr tool JAR file will be checked in to your source code control though, so you are free to use any other
way of specifying the version of the ANTLR tool to use, such as aliasing in `.zshrc` or equivalent, or a profile in
your IDE, or configuration in your CI system.
Here is a general template for an ANTLR based recognizer in Go:
.
├── myproject
├── parser
│ ├── mygrammar.g4
│ ├── antlr-4.12.0-complete.jar
│ ├── error_listeners.go
│ ├── generate.go
│ ├── generate.sh
├── go.mod
├── go.sum
├── main.go
└── main_test.go
Make sure that the package statement in your grammar file(s) reflects the go package they exist in.
The generate.go file then looks like this:
package parser
//go:generate ./generate.sh
And the generate.sh file will look similar to this:
#!/bin/sh
alias antlr4='java -Xmx500M -cp "./antlr4-4.12.0-complete.jar:$CLASSPATH" org.antlr.v4.Tool'
antlr4 -Dlanguage=Go -no-visitor -package parser *.g4
depending on whether you want visitors or listeners or any other ANTLR options.
From the command line at the root of your package “myproject” you can then simply issue the command:
go generate ./...

// Computes the SLL prediction termination condition.
//
// <p>
// This method computes the SLL prediction termination condition for both of
// the following cases.</p>
//
// <ul>
// <li>The usual SLL+LL fallback upon SLL conflict</li>
// <li>Pure SLL without LL fallback</li>
// </ul>
//
// <p><strong>COMBINED SLL+LL PARSING</strong></p>
//
// <p>When LL-fallback is enabled upon SLL conflict, correct predictions are
// ensured regardless of how the termination condition is computed by this
// method. Due to the substantially higher cost of LL prediction, the
// prediction should only fall back to LL when the additional lookahead
// cannot lead to a unique SLL prediction.</p>
//
// <p>Assuming combined SLL+LL parsing, an SLL configuration set with only
// conflicting subsets should fall back to full LL, even if the
// configuration sets don't resolve to the same alternative (e.g.
// {@code {1,2}} and {@code {3,4}}. If there is at least one non-conflicting
// configuration, SLL could continue with the hopes that more lookahead will
// resolve via one of those non-conflicting configurations.</p>
//
// <p>Here's the prediction termination rule them: SLL (for SLL+LL parsing)
// stops when it sees only conflicting configuration subsets. In contrast,
// full LL keeps going when there is uncertainty.</p>
//
// <p><strong>HEURISTIC</strong></p>
//
// <p>As a heuristic, we stop prediction when we see any conflicting subset
// unless we see a state that only has one alternative associated with it.
// The single-alt-state thing lets prediction continue upon rules like
// (otherwise, it would admit defeat too soon):</p>
//
// <p>{@code [12|1|[], 6|2|[], 12|2|[]]. s : (ID | ID ID?) ” }</p>
//
// <p>When the ATN simulation reaches the state before {@code ”}, it has a
// DFA state that looks like: {@code [12|1|[], 6|2|[], 12|2|[]]}. Naturally
// {@code 12|1|[]} and {@code 12|2|[]} conflict, but we cannot stop
// processing this node because alternative to has another way to continue,
// via {@code [6|2|[]]}.</p>
//
// <p>It also let's us continue for this rule:</p>
//
// <p>{@code [1|1|[], 1|2|[], 8|3|[]] a : A | A | A B }</p>
//
// <p>After Matching input A, we reach the stop state for rule A, state 1.
// State 8 is the state right before B. Clearly alternatives 1 and 2
// conflict and no amount of further lookahead will separate the two.
// However, alternative 3 will be able to continue and so we do not stop
// working on this state. In the previous example, we're concerned with
// states associated with the conflicting alternatives. Here alt 3 is not
// associated with the conflicting configs, but since we can continue
// looking for input reasonably, don't declare the state done.</p>
//
// <p><strong>PURE SLL PARSING</strong></p>
//
// <p>To handle pure SLL parsing, all we have to do is make sure that we
// combine stack contexts for configurations that differ only by semantic
// predicate. From there, we can do the usual SLL termination heuristic.</p>
//
// <p><strong>PREDICATES IN SLL+LL PARSING</strong></p>
//
// <p>SLL decisions don't evaluate predicates until after they reach DFA stop
// states because they need to create the DFA cache that works in all
// semantic situations. In contrast, full LL evaluates predicates collected
// during start state computation so it can ignore predicates thereafter.
// This means that SLL termination detection can totally ignore semantic
// predicates.</p>
//
// <p>Implementation-wise, {@link ATNConfigSet} combines stack contexts but not
// semantic predicate contexts so we might see two configurations like the
// following.</p>
//
// <p>{@code (s, 1, x, {}), (s, 1, x', {p})}</p>
//
// <p>Before testing these configurations against others, we have to merge
// {@code x} and {@code x'} (without modifying the existing configurations).
// For example, we test {@code (x+x')==x”} when looking for conflicts in
// the following configurations.</p>
//
// <p>{@code (s, 1, x, {}), (s, 1, x', {p}), (s, 2, x”, {})}</p>
//
// <p>If the configuration set has predicates (as indicated by
// {@link ATNConfigSet//hasSemanticContext}), this algorithm makes a copy of
// the configurations to strip out all of the predicates so that a standard
// {@link ATNConfigSet} will merge everything ignoring predicates.</p>

// <p>Can we stop looking ahead during ATN simulation or is there some
// uncertainty as to which alternative we will ultimately pick, after
// consuming more input? Even if there are partial conflicts, we might know
// that everything is going to resolve to the same minimum alternative. That
// means we can stop since no more lookahead will change that fact. On the
// other hand, there might be multiple conflicts that resolve to different
// minimums. That means we need more look ahead to decide which of those
// alternatives we should predict.</p>
//
// <p>The basic idea is to split the set of configurations {@code C}, into
// conflicting subsets {@code (s, _, ctx, _)} and singleton subsets with
// non-conflicting configurations. Two configurations conflict if they have
// identical {@link ATNConfig//state} and {@link ATNConfig//context} values
// but different {@link ATNConfig//alt} value, e.g. {@code (s, i, ctx, _)}
// and {@code (s, j, ctx, _)} for {@code i!=j}.</p>
//
// <p>Reduce these configuration subsets to the set of possible alternatives.
// You can compute the alternative subsets in one pass as follows:</p>
//
// <p>{@code A_s,ctx = {i | (s, i, ctx, _)}} for each configuration in
// {@code C} holding {@code s} and {@code ctx} fixed.</p>
//
// <p>Or in pseudo-code, for each configuration {@code c} in {@code C}:</p>
//
// <pre>
// map[c] U= c.{@link ATNConfig//alt alt} // map hash/equals uses s and x, not
// alt and not pred
// </pre>
//
// <p>The values in {@code map} are the set of {@code A_s,ctx} sets.</p>
//
// <p>If {@code |A_s,ctx|=1} then there is no conflict associated with
// {@code s} and {@code ctx}.</p>
//
// <p>Reduce the subsets to singletons by choosing a minimum of each subset. If
// the union of these alternative subsets is a singleton, then no amount of
// more lookahead will help us. We will always pick that alternative. If,
// however, there is more than one alternative, then we are uncertain which
// alternative to predict and must continue looking for resolution. We may
// or may not discover an ambiguity in the future, even if there are no
// conflicting subsets this round.</p>
//
// <p>The biggest sin is to terminate early because it means we've made a
// decision but were uncertain as to the eventual outcome. We haven't used
// enough lookahead. On the other hand, announcing a conflict too late is no
// big deal you will still have the conflict. It's just inefficient. It
// might even look until the end of file.</p>
//
// <p>No special consideration for semantic predicates is required because
// predicates are evaluated on-the-fly for full LL prediction, ensuring that
// no configuration contains a semantic context during the termination
// check.</p>
//
// <p><strong>CONFLICTING CONFIGS</strong></p>
//
// <p>Two configurations {@code (s, i, x)} and {@code (s, j, x')}, conflict
// when {@code i!=j} but {@code x=x'}. Because we merge all
// {@code (s, i, _)} configurations together, that means that there are at
// most {@code n} configurations associated with state {@code s} for
// {@code n} possible alternatives in the decision. The merged stacks
// complicate the comparison of configuration contexts {@code x} and
// {@code x'}. Sam checks to see if one is a subset of the other by calling
// merge and checking to see if the merged result is either {@code x} or
// {@code x'}. If the {@code x} associated with lowest alternative {@code i}
// is the superset, then {@code i} is the only possible prediction since the
// others resolve to {@code min(i)} as well. However, if {@code x} is
// associated with {@code j>i} then at least one stack configuration for
// {@code j} is not in conflict with alternative {@code i}. The algorithm
// should keep going, looking for more lookahead due to the uncertainty.</p>
//
// <p>For simplicity, I'm doing a equality check between {@code x} and
// {@code x'} that lets the algorithm continue to consume lookahead longer
// than necessary. The reason I like the equality is of course the
// simplicity but also because that is the test you need to detect the
// alternatives that are actually in conflict.</p>
//
// <p><strong>CONTINUE/STOP RULE</strong></p>
//
// <p>Continue if union of resolved alternative sets from non-conflicting and
// conflicting alternative subsets has more than one alternative. We are
// uncertain about which alternative to predict.</p>
//
// <p>The complete set of alternatives, {@code [i for (_,i,_)]}, tells us which
// alternatives are still in the running for the amount of input we've
// consumed at this point. The conflicting sets let us to strip away

# ANTLR4 Go Runtime Module Repo
IMPORTANT: Please submit PRs via a clone of the https://github.com/antlr/antlr4 repo, and not here.
- Do not submit PRs or any change requests to this repo
- This repo is read only and is updated by the ANTLR team to create a new release of the Go Runtime for ANTLR
- This repo contains the Go runtime that your generated projects should import
## Introduction
This repo contains the official modules for the Go Runtime for ANTLR. It is a copy of the runtime maintained
at: https://github.com/antlr/antlr4/tree/master/runtime/Go/antlr and is automatically updated by the ANTLR team to create
the official Go runtime release only. No development work is carried out in this repo and PRs are not accepted here.
The dev branch of this repo is kept in sync with the dev branch of the main ANTLR repo and is updated periodically.
### Why?
The `go get` command is unable to retrieve the Go runtime when it is embedded so
deeply in the main repo. A `go get` against the `antlr/antlr4` repo, while retrieving the correct source code for the runtime,
does not correctly resolve tags and will create a reference in your `go.mod` file that is unclear, will not upgrade smoothly and
causes confusion.
For instance, the current Go runtime release, which is tagged with v4.13.0 in `antlr/antlr4` is retrieved by go get as:
```sh
require (
github.com/antlr/antlr4/runtime/Go/antlr/v4 v4.0.0-20230219212500-1f9a474cc2dc
)
```
Where you would expect to see:
```sh
require (
github.com/antlr/antlr4/runtime/Go/antlr/v4 v4.13.0
)
```
The decision was taken to create a separate org in a separate repo to hold the official Go runtime for ANTLR and
from whence users can expect `go get` to behave as expected.
# Documentation
Please read the official documentation at: https://github.com/antlr/antlr4/blob/master/doc/index.md for tips on
migrating existing projects to use the new module location and for information on how to use the Go runtime in
general.

/*
Package antlr implements the Go version of the ANTLR 4 runtime.
# The ANTLR Tool
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing,
or translating structured text or binary files. It's widely used to build languages, tools, and frameworks.
From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface
(or visitor) that makes it easy to respond to the recognition of phrases of interest.
# Go Runtime
At version 4.11.x and prior, the Go runtime was not properly versioned for go modules. After this point, the runtime
source code to be imported was held in the `runtime/Go/antlr/v4` directory, and the go.mod file was updated to reflect the version of
ANTLR4 that it is compatible with (I.E. uses the /v4 path).
However, this was found to be problematic, as it meant that with the runtime embedded so far underneath the root
of the repo, the `go get` and related commands could not properly resolve the location of the go runtime source code.
This meant that the reference to the runtime in your `go.mod` file would refer to the correct source code, but would not
list the release tag such as @4.12.0 - this was confusing, to say the least.
As of 4.12.1, the runtime is now available as a go module in its own repo, and can be imported as `github.com/antlr4-go/antlr`
(the go get command should also be used with this path). See the main documentation for the ANTLR4 project for more information,
which is available at [ANTLR docs]. The documentation for using the Go runtime is available at [Go runtime docs].
This means that if you are using the source code without modules, you should also use the source code in the [new repo].
Though we highly recommend that you use go modules, as they are now idiomatic for Go.
I am aware that this change will prove Hyrum's Law, but am prepared to live with it for the common good.
Go runtime author: [Jim Idle] jimi@idle.ws
# Code Generation
ANTLR supports the generation of code in a number of [target languages], and the generated code is supported by a
runtime library, written specifically to support the generated code in the target language. This library is the
runtime for the Go target.
To generate code for the go target, it is generally recommended to place the source grammar files in a package of
their own, and use the `.sh` script method of generating code, using the go generate directive. In that same directory
it is usual, though not required, to place the antlr tool that should be used to generate the code. That does mean
that the antlr tool JAR file will be checked in to your source code control though, so you are, of course, free to use any other
way of specifying the version of the ANTLR tool to use, such as aliasing in `.zshrc` or equivalent, or a profile in
your IDE, or configuration in your CI system. Checking in the jar does mean that it is easy to reproduce the build as
it was at any point in its history.
Here is a general/recommended template for an ANTLR based recognizer in Go:
.
├── parser
│ ├── mygrammar.g4
│ ├── antlr-4.12.1-complete.jar
│ ├── generate.go
│ └── generate.sh
├── parsing - generated code goes here
│ └── error_listeners.go
├── go.mod
├── go.sum
├── main.go
└── main_test.go
Make sure that the package statement in your grammar file(s) reflects the go package the generated code will exist in.
The generate.go file then looks like this:
package parser
//go:generate ./generate.sh
And the generate.sh file will look similar to this:
#!/bin/sh
alias antlr4='java -Xmx500M -cp "./antlr4-4.12.1-complete.jar:$CLASSPATH" org.antlr.v4.Tool'
antlr4 -Dlanguage=Go -no-visitor -package parsing *.g4
depending on whether you want visitors or listeners or any other ANTLR options. Not that another option here
is to generate the code into a
From the command line at the root of your source package (location of go.mo)d) you can then simply issue the command:
go generate ./...
Which will generate the code for the parser, and place it in the parsing package. You can then use the generated code
by importing the parsing package.
There are no hard and fast rules on this. It is just a recommendation. You can generate the code in any way and to anywhere you like.

// - The usual SLL+LL fallback upon SLL conflict
// - Pure SLL without LL fallback
//
// # Combined SLL+LL Parsing
//
// When LL-fallback is enabled upon SLL conflict, correct predictions are
// ensured regardless of how the termination condition is computed by this
// method. Due to the substantially higher cost of LL prediction, the
// prediction should only fall back to LL when the additional lookahead
// cannot lead to a unique SLL prediction.
//
// Assuming combined SLL+LL parsing, an SLL configuration set with only
// conflicting subsets should fall back to full LL, even if the
// configuration sets don't resolve to the same alternative, e.g.
//
// {1,2} and {3,4}
//
// If there is at least one non-conflicting
// configuration, SLL could continue with the hopes that more lookahead will
// resolve via one of those non-conflicting configurations.
//
// Here's the prediction termination rule them: SLL (for SLL+LL parsing)
// stops when it sees only conflicting configuration subsets. In contrast,
// full LL keeps going when there is uncertainty.
//
// # Heuristic
//
// As a heuristic, we stop prediction when we see any conflicting subset
// unless we see a state that only has one alternative associated with it.
// The single-alt-state thing lets prediction continue upon rules like
// (otherwise, it would admit defeat too soon):
//
// [12|1|[], 6|2|[], 12|2|[]]. s : (ID | ID ID?) ;
//
// When the [ATN] simulation reaches the state before ';', it has a
// [DFA] state that looks like:
//
// [12|1|[], 6|2|[], 12|2|[]]
//
// Naturally
//
// 12|1|[] and 12|2|[]
//
// conflict, but we cannot stop processing this node because alternative to has another way to continue,
// via
//
// [6|2|[]]
//
// It also let's us continue for this rule:
//
// [1|1|[], 1|2|[], 8|3|[]] a : A | A | A B ;
//
// After Matching input A, we reach the stop state for rule A, state 1.
// State 8 is the state immediately before B. Clearly alternatives 1 and 2
// conflict and no amount of further lookahead will separate the two.
// However, alternative 3 will be able to continue, and so we do not stop
// working on this state. In the previous example, we're concerned with
// states associated with the conflicting alternatives. Here alt 3 is not
// associated with the conflicting configs, but since we can continue
// looking for input reasonably, don't declare the state done.
//
// # Pure SLL Parsing
//
// To handle pure SLL parsing, all we have to do is make sure that we
// combine stack contexts for configurations that differ only by semantic
// predicate. From there, we can do the usual SLL termination heuristic.
//
// # Predicates in SLL+LL Parsing
//
// SLL decisions don't evaluate predicates until after they reach [DFA] stop
// states because they need to create the [DFA] cache that works in all
// semantic situations. In contrast, full LL evaluates predicates collected
// during start state computation, so it can ignore predicates thereafter.
// This means that SLL termination detection can totally ignore semantic
// predicates.
//
// Implementation-wise, [ATNConfigSet] combines stack contexts but not
// semantic predicate contexts, so we might see two configurations like the
// following:
//
// (s, 1, x, {}), (s, 1, x', {p})
//
// Before testing these configurations against others, we have to merge
// x and x' (without modifying the existing configurations).
// For example, we test (x+x')==x” when looking for conflicts in
// the following configurations:
//
// (s, 1, x, {}), (s, 1, x', {p}), (s, 2, x”, {})

// If the configuration set has predicates (as indicated by

// Can we stop looking ahead during [ATN] simulation or is there some

// means we can stop since no more lookahead will change that fact. On the
// other hand, there might be multiple conflicts that resolve to different
// minimums. That means we need more look ahead to decide which of those
// alternatives we should predict.
//
// The basic idea is to split the set of configurations 'C', into
// conflicting subsets (s, _, ctx, _) and singleton subsets with
// non-conflicting configurations. Two configurations conflict if they have
// identical [ATNConfig].state and [ATNConfig].context values
// but a different [ATNConfig].alt value, e.g.
//
// (s, i, ctx, _)
//
// and
//
// (s, j, ctx, _) ; for i != j
//
// Reduce these configuration subsets to the set of possible alternatives.
// You can compute the alternative subsets in one pass as follows:
//
// A_s,ctx = {i | (s, i, ctx, _)}
//
// for each configuration in C holding s and ctx fixed.
//
// Or in pseudo-code:
//
// for each configuration c in C:
// map[c] U = c.ATNConfig.alt alt // map hash/equals uses s and x, not alt and not pred
//
// The values in map are the set of
//
// A_s,ctx
//
// sets.
//
// If
//
// |A_s,ctx| = 1
//
// then there is no conflict associated with s and ctx.
//
// Reduce the subsets to singletons by choosing a minimum of each subset. If
// the union of these alternative subsets is a singleton, then no amount of
// further lookahead will help us. We will always pick that alternative. If,
// however, there is more than one alternative, then we are uncertain which
// alternative to predict and must continue looking for resolution. We may
// or may not discover an ambiguity in the future, even if there are no
// conflicting subsets this round.
//
// The biggest sin is to terminate early because it means we've made a
// decision but were uncertain as to the eventual outcome. We haven't used
// enough lookahead. On the other hand, announcing a conflict too late is no
// big deal; you will still have the conflict. It's just inefficient. It
// might even look until the end of file.
//
// No special consideration for semantic predicates is required because
// predicates are evaluated on-the-fly for full LL prediction, ensuring that
// no configuration contains a semantic context during the termination
// check.
//
// # Conflicting Configs
//
// Two configurations:
//
// (s, i, x) and (s, j, x')
//
// conflict when i != j but x = x'. Because we merge all
// (s, i, _) configurations together, that means that there are at
// most n configurations associated with state s for
// n possible alternatives in the decision. The merged stacks
// complicate the comparison of configuration contexts x and x'.
//
// Sam checks to see if one is a subset of the other by calling
// merge and checking to see if the merged result is either x or x'.
// If the x associated with lowest alternative i
// is the superset, then i is the only possible prediction since the
// others resolve to min(i) as well. However, if x is
// associated with j > i then at least one stack configuration for
// j is not in conflict with alternative i. The algorithm
// should keep going, looking for more lookahead due to the uncertainty.
//
// For simplicity, I'm doing an equality check between x and
// x', which lets the algorithm continue to consume lookahead longer
// than necessary. The reason I like the equality is of course the
// simplicity but also because that is the test you need to detect the
// alternatives that are actually in conflict.
//
// # Continue/Stop Rule
//
// Continue if the union of resolved alternative sets from non-conflicting and
// conflicting alternative subsets has more than one alternative. We are
// uncertain about which alternative to predict.
//
// The complete set of alternatives,
//
// [i for (_, i, _)]
//
// tells us which alternatives are still in the running for the amount of input we've
// consumed at this point. The conflicting sets let us to strip away
// configurations that won't lead to more states because we resolve
// conflicts to the configuration with a minimum alternate for the
// conflicting set.
//
// Cases
//
// - no conflicts and more than 1 alternative in set => continue
// - (s, 1, x), (s, 2, x), (s, 3, z), (s', 1, y), (s', 2, y) yields non-conflicting set
// {3} ∪ conflicting sets min({1,2}) ∪ min({1,2}) = {1,3} => continue
// - (s, 1, x), (s, 2, x), (s', 1, y), (s', 2, y), (s”, 1, z) yields non-conflicting set
// {1} ∪ conflicting sets min({1,2}) ∪ min({1,2}) = {1} => stop and predict 1
// - (s, 1, x), (s, 2, x), (s', 1, y), (s', 2, y) yields conflicting, reduced sets
// {1} ∪ {1} = {1} => stop and predict 1, can announce ambiguity {1,2}

//

// know we have the exact ambiguity set:
//
// |A_i| > 1
//
// and
//
// A_i = A_j ; for all i, j
//
// In other words, we continue examining lookahead until all A_i
// have more than one alternative and all A_i are the same. If

## Community help
If you need help, please ask in the [#distribution](https://cloud-native.slack.com/archives/C01GVR8SY4R) channel on CNCF community slack.
[Click here for an invite to the CNCF community slack](https://slack.cncf.io/)
## Reporting security issues
The maintainers take security seriously. If you discover a security
issue, please bring it to their attention right away!
Please **DO NOT** file a public issue, instead send your report privately to
[cncf-distribution-security@lists.cncf.io](mailto:cncf-distribution-security@lists.cncf.io).
## Reporting an issue properly
By following these simple rules you will get better and faster feedback on your issue.
- search the bugtracker for an already reported issue
### If you found an issue that describes your problem:
- please read other user comments first, and confirm this is the same issue: a given error condition might be indicative of different problems - you may also find a workaround in the comments
- please refrain from adding "same thing here" or "+1" comments
- you don't need to comment on an issue to get notified of updates: just hit the "subscribe" button
- comment if you have some new, technical and relevant information to add to the case
- __DO NOT__ comment on closed issues or merged PRs. If you think you have a related problem, open up a new issue and reference the PR or issue.
### If you have not found an existing issue that describes your problem:
1. create a new issue, with a succinct title that describes your issue:
- bad title: "It doesn't work with my docker"
- good title: "Private registry push fail: 400 error with E_INVALID_DIGEST"
2. copy the output of (or similar for other container tools):
- `docker version`
- `docker info`
- `docker exec <registry-container> registry --version`
3. copy the command line you used to launch your Registry
4. restart your docker daemon in debug mode (add `-D` to the daemon launch arguments)
5. reproduce your problem and get your docker daemon logs showing the error
6. if relevant, copy your registry logs that show the error
7. provide any relevant detail about your specific Registry configuration (e.g., storage backend used)
8. indicate if you are using an enterprise proxy, Nginx, or anything else between you and your Registry
## Contributing Code
Contributions should be made via pull requests. Pull requests will be reviewed
by one or more maintainers or reviewers and merged when acceptable.
You should follow the basic GitHub workflow:
1. Use your own [fork](https://help.github.com/en/articles/about-forks)
2. Create your [change](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
3. Test your code
4. [Commit](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages) your work, always [sign your commits](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages)
5. Push your change to your fork and create a [Pull Request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork)
Refer to [containerd's contribution guide](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
for tips on creating a successful contribution.
## 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`.

# distribution/reference Project Governance
Distribution [Code of Conduct](./CODE-OF-CONDUCT.md) can be found here.
For specific guidance on practical contribution steps please
see our [CONTRIBUTING.md](./CONTRIBUTING.md) guide.
## Maintainership
There are different types of maintainers, with different responsibilities, but
all maintainers have 3 things in common:
1) They share responsibility in the project's success.
2) They have made a long-term, recurring time investment to improve the project.
3) They spend that time doing whatever needs to be done, not necessarily what
is the most interesting or fun.
Maintainers are often under-appreciated, because their work is harder to appreciate.
It's easy to appreciate a really cool and technically advanced feature. It's harder
to appreciate the absence of bugs, the slow but steady improvement in stability,
or the reliability of a release process. But those things distinguish a good
project from a great one.
## Reviewers
A reviewer is a core role within the project.
They share in reviewing issues and pull requests and their LGTM counts towards the
required LGTM count to merge a code change into the project.
Reviewers are part of the organization but do not have write access.
Becoming a reviewer is a core aspect in the journey to becoming a maintainer.
## Adding maintainers
Maintainers are first and foremost contributors that have shown they are
committed to the long term success of a project. Contributors wanting to become
maintainers are expected to be deeply involved in contributing code, pull
request review, and triage of issues in the project for more than three months.
Just contributing does not make you a maintainer, it is about building trust
with the current maintainers of the project and being a person that they can
depend on and trust to make decisions in the best interest of the project.
Periodically, the existing maintainers curate a list of contributors that have
shown regular activity on the project over the prior months. From this list,
maintainer candidates are selected and proposed in a pull request or a
maintainers communication channel.
After a candidate has been announced to the maintainers, the existing
maintainers are given five business days to discuss the candidate, raise
objections and cast their vote. Votes may take place on the communication
channel or via pull request comment. Candidates must be approved by at least 66%
of the current maintainers by adding their vote on the mailing list. The
reviewer role has the same process but only requires 33% of current maintainers.
Only maintainers of the repository that the candidate is proposed for are
allowed to vote.
If a candidate is approved, a maintainer will contact the candidate to invite
the candidate to open a pull request that adds the contributor to the
MAINTAINERS file. The voting process may take place inside a pull request if a
maintainer has already discussed the candidacy with the candidate and a
maintainer is willing to be a sponsor by opening the pull request. The candidate
becomes a maintainer once the pull request is merged.
## Stepping down policy
Life priorities, interests, and passions can change. If you're a maintainer but
feel you must remove yourself from the list, inform other maintainers that you
intend to step down, and if possible, help find someone to pick up your work.
At the very least, ensure your work can be continued where you left off.
After you've informed other maintainers, create a pull request to remove
yourself from the MAINTAINERS file.
## Removal of inactive maintainers
Similar to the procedure for adding new maintainers, existing maintainers can
be removed from the list if they do not show significant activity on the
project. Periodically, the maintainers review the list of maintainers and their
activity over the last three months.
If a maintainer has shown insufficient activity over this period, a neutral
person will contact the maintainer to ask if they want to continue being
a maintainer. If the maintainer decides to step down as a maintainer, they
open a pull request to be removed from the MAINTAINERS file.
If the maintainer wants to remain a maintainer, but is unable to perform the
required duties they can be removed with a vote of at least 66% of the current
maintainers. In this case, maintainers should first propose the change to
maintainers via the maintainers communication channel, then open a pull request
for voting. The voting period is five business days. The voting pull request
should not come as a surpise to any maintainer and any discussion related to
performance must not be discussed on the pull request.
## How are decisions made?
Docker distribution is an open-source project with an open design philosophy.
This means that the repository is the source of truth for EVERY aspect of the
project, including its philosophy, design, road map, and APIs. *If it's part of
the project, it's in the repo. If it's in the repo, it's part of the project.*
As a result, all decisions can be expressed as changes to the repository. An
implementation change is a change to the source code. An API change is a change
to the API specification. A philosophy change is a change to the philosophy
manifesto, and so on.
All decisions affecting distribution, big and small, follow the same 3 steps:
* Step 1: Open a pull request. Anyone can do this.
* Step 2: Discuss the pull request. Anyone can do this.
* Step 3: Merge or refuse the pull request. Who does this depends on the nature
of the pull request and which areas of the project it affects.
## Helping contributors with the DCO
The [DCO or `Sign your work`](./CONTRIBUTING.md#sign-your-work)
requirement is not intended as a roadblock or speed bump.
Some contributors are not as familiar with `git`, or have used a web
based editor, and thus asking them to `git commit --amend -s` is not the best
way forward.
In this case, maintainers can update the commits based on clause (c) of the DCO.
The most trivial way for a contributor to allow the maintainer to do this, is to
add a DCO signature in a pull requests's comment, or a maintainer can simply
note that the change is sufficiently trivial that it does not substantially
change the existing contribution - i.e., a spelling change.
When you add someone's DCO, please also add your own to keep a log.
## I'm a maintainer. Should I make pull requests too?
Yes. Nobody should ever push to master directly. All changes should be
made through a pull request.
## Conflict Resolution
If you have a technical dispute that you feel has reached an impasse with a
subset of the community, any contributor may open an issue, specifically
calling for a resolution vote of the current core maintainers to resolve the
dispute. The same voting quorums required (2/3) for adding and removing
maintainers will apply to conflict resolution.

# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, caste, color, religion, or sexual
identity and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the overall
community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or advances of
any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email address,
without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
faye.github@gmail.com.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series of
actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or permanent
ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within the
community.

# How to contribute
You can contribute by using the library, opening issues, or opening pull requests.
## Bug reports and security vulnerabilities
Most issues are tracked publicly on [GitHub](https://github.com/fxamacker/cbor/issues).
To report security vulnerabilities, please email faye.github@gmail.com and allow time for the problem to be resolved before disclosing it to the public. For more info, see [Security Policy](https://github.com/fxamacker/cbor#security-policy).
Please do not send data that might contain personally identifiable information, even if you think you have permission. That type of support requires payment and a signed contract where I'm indemnified, held harmless, and defended by you for any data you send to me.
## Pull requests
Please [create an issue](https://github.com/fxamacker/cbor/issues/new/choose) before you begin work on a PR. The improvement may have already been considered, etc.
Pull requests have signing requirements and must not be anonymous. Exceptions are usually made for docs and CI scripts.
See the [Pull Request Template](https://github.com/fxamacker/cbor/blob/master/.github/pull_request_template.md) for details.
Pull requests have a greater chance of being approved if:
- it does not reduce speed, increase memory use, reduce security, etc. for people not using the new option or feature.
- it has > 97% code coverage.
## Describe your issue
Clearly describe the issue:
* If it's a bug, please provide: **version of this library** and **Go** (`go version`), **unmodified error message**, and describe **how to reproduce it**. Also state **what you expected to happen** instead of the error.
* If you propose a change or addition, try to give an example how the improved code could look like or how to use it.
* If you found a compilation error, please confirm you're using a supported version of Go. If you are, then provide the output of `go version` first, followed by the complete error message.
## Please don't
Please don't send data containing personally identifiable information, even if you think you have permission. That type of support requires payment and a contract where I'm indemnified, held harmless, and defended for any data you send to me.
Please don't send CBOR data larger than 1024 bytes by email. If you want to send crash-producing CBOR data > 1024 bytes by email, please get my permission before sending it to me.
## Credits
- This guide used nlohmann/json contribution guidelines for inspiration as suggested in issue #22.
- Special thanks to @lukseven for pointing out the contribution guidelines didn't mention signing requirements.
