// Package xts implements the XTS cipher mode as specified in IEEE P1619/D16.
//
// XTS mode is typically used for disk encryption, which presents a number of
// novel problems that make more common modes inapplicable. The disk is
// conceptually an array of sectors and we must be able to encrypt and decrypt
// a sector in isolation. However, an attacker must not be able to transpose
// two sectors of plaintext by transposing their ciphertext.
//
// XTS wraps a block cipher with Rogaway's XEX mode in order to build a
// tweakable block cipher. This allows each sector to have a unique tweak and
// effectively create a unique key for each sector.
//
// XTS does not provide any authentication. An attacker can manipulate the
// ciphertext and randomise a block (16 bytes) of the plaintext. This package
// does not implement ciphertext-stealing so sectors must be a multiple of 16
// bytes.

### Atom
Atoms are a source at a particular version. In practice, this means a two-tuple of [project root](#project-root) and version, e.g. `github.com/foo/bar@master`. Atoms are primarily internal to the [solver](#solver), and the term is rarely used elsewhere.
### Cache lock
Also "cache lock file." A file, named `sm.lock`, used to ensure only a single dep process operates on the [local cache](#local-cache) at a time, as it is unsafe in dep's current design for multiple processes to access the local cache.
### Constraint
Constraints have both a narrow and a looser meaning. The narrow sense refers to a [`[[constraint]]`](Gopkg.toml.md#constraint) stanza in `Gopkg.toml`. However, in some contexts, the word may be used more loosely to refer to the idea of applying rules and requirements to dependency management in general.
### Current Project
The project on which dep is operating - writing its `Gopkg.lock` and populating its `vendor` directory.
Also called the "root project."
### Deducible
A shorthand way of referring to whether or not import path [deduction](#deduction) will return successfully for a given import path. "Undeducible" is also often used, to refer to an import path for which deduction fails.
### Deduction
Deduction is the process of determining the subset of an import path that corresponds to a source root. Some patterns are known a priori (static); others must be discovered via network requests (dynamic). See the reference on [import path deduction](deduction.md) for specifics.
### Direct Dependency
A project's direct dependencies are those that it _imports_ from one or more of its packages, or includes in its [`required`](Gopkg.toml.md#required) list in `Gopkg.toml`.
If each letter in `A -> B -> C -> D` represents a distinct project containing only a single package, and `->` indicates an import statement, then `B` is `A`'s direct dependency, whereas `C` and `D` are [transitive dependencies](#transitive-dependency) of `A`.
Dep only incorporates the `required` rules from the [current project's](#current-project) `Gopkg.toml`. Therefore, if `=>` represents `required` rather than a standard import, and `A -> B => C`, then `C` is a direct dependency of `B` _only_ when `B` is the current project. Because the `B`-to-`C` link does not exist when `A` is the current project, then `C` won't actually be in the graph at all.
### External Import
An `import` statement that points to a package in a project other than the one in which it originates. For example, an `import` in package `github.com/foo/bar` will be considered an external import if it points to anything _other_ than stdlib or `github.com/foo/bar/*`.
### GPS
Acronym for "Go packaging solver", it is [a subtree of library-style packages within dep](https://godoc.org/github.com/golang/dep/gps), and is the engine around which dep is built. Most commonly referred to as "gps."
### Local cache
dep maintains its own, pristine set of upstream sources (so, generally, git repository clones). This is kept separate from `$GOPATH/src` so that there is no obligation to maintain disk state within `$GOPATH`, as dep frequently needs to change disk state in order to do its work.
By default, the local cache lives at `$GOPATH/pkg/dep`. If you have multiple `$GOPATH` entries, dep will use whichever is the logical parent of the process' working directory. Alternatively, the location can be forced via the [`DEPCACHEDIR` environment variable](env-vars.md#depcachedir).
### Lock
A generic term, used across many language package managers, for the kind of information dep keeps in a `Gopkg.lock` file.
### Manifest
A generic term, used across many language package managers, for the kind of information dep keeps in a `Gopkg.toml` file.
### Metadata Service
An HTTP service that, when it receives an HTTP request containing a `go-get=1` in the query string, treats interprets the path portion of the request as an import path, and responds by embedding data in HTML `<meta>` tags that indicate the type and URL of of the underlying source root. This is the server-side component of dynamic [deduction](#deduction).
The behavior of metadata services is defined in the [Go documentation on remote import paths](https://golang.org/cmd/go/#hdr-Remote_import_paths).
Variously referenced as "HTTP metadata service", "`go-get` HTTP metadata service", "`go-get` service", etc.
### Override
An override is a [`[[override]]`](Gopkg.toml.md#override) stanza in `Gopkg.toml`.
### Project
A project is a tree of Go packages. Projects cannot be nested. See [Project Root](#project-root) for more information about how the root of the tree is determined.
### Project Root
The root import path for a project. A project root is defined as:
* For the current project, the location of the `Gopkg.toml` file defines the project root
* For dependencies, the root of the network [source](#source) (VCS repository) is treated as the project root
These are generally one and the same, though not always. When using dep inside a monorepo, multiple `Gopkg.toml` files may exist at subpaths for discrete projects, designating each of those import paths as Project Roots. This works fine when working directly on those projects. If, however, any project not in the repository seeks to import the monorepo, dep will treat the monorepo as one big Project, with the root directory being the Project Root; it will disregard any and all `Gopkg.toml` files in subdirectories.
This may also be referred to as the "import root" or "root import path."
### Solver
"The solver" is a reference to the domain-specific SAT solver contained in [gps](#gps). More detail can be found on its [reference page](the-solver.md).
### Source
The remote entities that hold versioned code. Sources are specifically the entity containing the code, not any particular version of the code itself.
"Source" is used in lieu of "VCS" because Go package management tools will soon learn to use more than just VCS systems.
### Source Root
The portion of an import path that corresponds to the network location of a source. This is similar to [Project Root](#project-root), but refers strictly to the second, network-oriented definition.
### Sync
Dep is designed around a well-defined relationship between four states:
1. `import` statements in `.go` files
2. `Gopkg.toml`
3. `Gopkg.lock`
4. The `vendor` directory
If any aspect of the relationship is unfulfilled (e.g., there is an `import` not reflected in `Gopkg.lock`, or a project that's missing from `vendor`), then dep considers the project to be "out of sync."
This concept is explored in detail in [ensure mechanics](ensure-mechanics.md#staying-in-sync).
### Transitive Dependency
A project's transitive dependencies are those dependencies that it does not import itself, but are imported by one of its dependencies.
If each letter in `A -> B -> C -> D` represents a distinct project containing only a single package, and `->` indicates an import statement, then `C` and `D` are `A`'s transitive dependencies, whereas `B` is a [direct dependency](#transitive-dependency) of `A`.
### Vendor Verification
Dep guarantees that `vendor/` contains exactly the expected code by hashing the contents of each project and storing the resulting [digest in Gopkg.lock](Gopkg.lock.md#digest). This digest is computed _after_ pruning rules are applied.
The digest is used to determine if the contents of `vendor/` need to be regenerated during a `dep ensure` run, and `dep check` uses it to determine whether `Gopkg.lock` and `vendor/` are in [sync](#sync). The [`noverify`](Gopkg.toml.md#noverify) list in `Gopkg.toml` can be used to bypass most of these verification behaviors. | dep/docs/glossary.md/0 | {

// ProjectRoot is the topmost import path in a tree of other import paths - the
// root of the tree. In gps' current design, ProjectRoots have to correspond to
// a repository root (mostly), but their real purpose is to identify the root
// import path of a "project", logically encompassing all child packages.
//
// Projects are a crucial unit of operation in gps. Constraints are declared by
// a project's manifest, and apply to all packages in a ProjectRoot's tree.
// Solving itself mostly proceeds on a project-by-project basis.
//
// Aliasing string types is usually a bit of an anti-pattern. gps does it here
// as a means of clarifying API intent. This is important because Go's package
// management domain has lots of different path-ish strings floating around:
//
// actual directories:
// /home/sdboyer/go/src/github.com/sdboyer/gps/example
// URLs:
// https://github.com/sdboyer/gps
// import paths:
// github.com/sdboyer/gps/example
// portions of import paths that refer to a package:
// example
// portions that could not possibly refer to anything sane:
// github.com/sdboyer
// portions that correspond to a repository root:
// github.com/sdboyer/gps
//
// While not a panacea, having ProjectRoot allows gps to clearly indicate via
// the type system when a path-ish string must have particular semantics.
type ProjectRoot string
// A ProjectIdentifier provides the name and source location of a dependency. It
// is related to, but differs in two key ways from, a plain import path.
//
// First, ProjectIdentifiers do not identify a single package. Rather, they
// encompass the whole tree of packages, including tree's root - the
// ProjectRoot. In gps' current design, this ProjectRoot almost always
// corresponds to the root of a repository.
//
// Second, ProjectIdentifiers can optionally carry a Source, which
// identifies where the underlying source code can be located on the network.
// These can be either a full URL, including protocol, or plain import paths.
// So, these are all valid data for Source:
//
// github.com/sdboyer/gps
// github.com/fork/gps
// git@github.com:sdboyer/gps
// https://github.com/sdboyer/gps
//
// With plain import paths, network addresses are derived purely through an
// algorithm. By having an explicit network name, it becomes possible to, for
// example, transparently substitute a fork for the original upstream source
// repository.
//
// Note that gps makes no guarantees about the actual import paths contained in
// a repository aligning with ImportRoot. If tools, or their users, specify an
// alternate Source that contains a repository with incompatible internal
// import paths, gps' solving operations will error. (gps does no import
// rewriting.)
//
// Also note that if different projects' manifests report a different
// Source for a given ImportRoot, it is a solve failure. Everyone has to
// agree on where a given import path should be sourced from.
//
// If Source is not explicitly set, gps will derive the network address from
// the ImportRoot using a similar algorithm to that utilized by `go get`.

//
// ignore is a map of import paths that, if encountered, should be excluded from
// analysis. This exclusion applies to both internal and external packages. If
// an external import path is ignored, it is simply omitted from the results.
//
// If an internal path is ignored, then it not only does not appear in the final
// map, but it is also excluded from the transitive calculations of other
// internal packages. That is, if you ignore A/foo, then the external package
// list for all internal packages that import A/foo will not include external
// packages that are only reachable through A/foo.
//
// Visually, this means that, given a PackageTree with root A and packages at A,
// A/foo, and A/bar, and the following import chain:
//
// A -> A/foo -> A/bar -> B/baz
//
// In this configuration, all of A's packages transitively import B/baz, so the

//
// map[string][]string{
// "A": []string{"B/baz"},
// "A/foo": []string{"B/baz"}
// "A/bar": []string{"B/baz"},

// omitted entirely. Thus, the returned map would be:
//
// map[string][]string{
// "A": []string{},
// "A/bar": []string{"B/baz"},
// }
//
// If there are no packages to ignore, it is safe to pass a nil map.
//
// Finally, if an internal PackageOrErr contains an error, it is always omitted
// from the result set. If backprop is true, then the error from that internal
// package will be transitively propagated back to any other internal
// PackageOrErrs that import it, causing them to also be omitted. So, with the
// same import chain:
//
// A -> A/foo -> A/bar -> B/baz
//
// If A/foo has an error, then it would backpropagate to A, causing both to be
// omitted, and the returned map to contain only A/bar:
//
// map[string][]string{
// "A/bar": []string{"B/baz"},
// }
//
// If backprop is false, then errors will not backpropagate to internal

omitempty When set, empty values and groups are not emitted.
comment:"comment" Emits a # comment on the same line. This supports new lines.
commented:"true" Emits the value as commented.
Note that pointers are automatically assigned the "omitempty" option, as TOML
explicitly does not handle null values (saying instead the label should be
dropped).

// Incoming requests to a server should create a Context, and outgoing calls to

//
// Programs that use Contexts should follow these rules to keep interfaces
// consistent across packages and enable static analysis tools to check context

//
// Do not store Contexts inside a struct type; instead, pass a Context
// explicitly to each function that needs it. The Context should be the first
// parameter, typically named ctx:
//
// func DoSomething(ctx context.Context, arg Arg) error {
// // ... use ctx ...
// }
//
// Do not pass a nil Context, even if a function permits it. Pass context.TODO
// if you are unsure about which Context to use.
//

// APIs, not for passing optional parameters to functions.

// Introduction
// ************
//
// The following notes assume that you are familiar with the YAML specification
// (http://yaml.org/spec/1.2/spec.html). We mostly follow it, although in
// some cases we are less restrictive that it requires.
//
// The process of transforming a YAML stream into a sequence of events is
// divided on two steps: Scanning and Parsing.
//
// The Scanner transforms the input stream into a sequence of tokens, while the
// parser transform the sequence of tokens produced by the Scanner into a
// sequence of parsing events.
//
// The Scanner is rather clever and complicated. The Parser, on the contrary,
// is a straightforward implementation of a recursive-descendant parser (or,
// LL(1) parser, as it is usually called).
//
// Actually there are two issues of Scanning that might be called "clever", the
// rest is quite straightforward. The issues are "block collection start" and
// "simple keys". Both issues are explained below in details.
//
// Here the Scanning step is explained and implemented. We start with the list
// of all the tokens produced by the Scanner together with short descriptions.
//
// Now, tokens:
//
// STREAM-START(encoding) # The stream start.
// STREAM-END # The stream end.
// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive.
// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive.
// DOCUMENT-START # '---'
// DOCUMENT-END # '...'
// BLOCK-SEQUENCE-START # Indentation increase denoting a block
// BLOCK-MAPPING-START # sequence or a block mapping.
// BLOCK-END # Indentation decrease.
// FLOW-SEQUENCE-START # '['
// FLOW-SEQUENCE-END # ']'
// BLOCK-SEQUENCE-START # '{'
// BLOCK-SEQUENCE-END # '}'
// BLOCK-ENTRY # '-'
// FLOW-ENTRY # ','
// KEY # '?' or nothing (simple keys).
// VALUE # ':'
// ALIAS(anchor) # '*anchor'
// ANCHOR(anchor) # '&anchor'
// TAG(handle,suffix) # '!handle!suffix'
// SCALAR(value,style) # A scalar.
//
// The following two tokens are "virtual" tokens denoting the beginning and the
// end of the stream:
//
// STREAM-START(encoding)
// STREAM-END
//
// We pass the information about the input stream encoding with the
// STREAM-START token.
//
// The next two tokens are responsible for tags:
//
// VERSION-DIRECTIVE(major,minor)
// TAG-DIRECTIVE(handle,prefix)
//
// Example:
//
// %YAML 1.1
// %TAG ! !foo
// %TAG !yaml! tag:yaml.org,2002:
// ---
//
// The correspoding sequence of tokens:
//
// STREAM-START(utf-8)
// VERSION-DIRECTIVE(1,1)
// TAG-DIRECTIVE("!","!foo")
// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
// DOCUMENT-START
// STREAM-END
//
// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
// line.
//
// The document start and end indicators are represented by:
//
// DOCUMENT-START
// DOCUMENT-END
//
// Note that if a YAML stream contains an implicit document (without '---'
// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
// produced.
//
// In the following examples, we present whole documents together with the
// produced tokens.
//
// 1. An implicit document:
//
// 'a scalar'
//
// Tokens:
//
// STREAM-START(utf-8)
// SCALAR("a scalar",single-quoted)
// STREAM-END
//
// 2. An explicit document:
//
// ---
// 'a scalar'
// ...
//
// Tokens:
//
// STREAM-START(utf-8)
// DOCUMENT-START
// SCALAR("a scalar",single-quoted)
// DOCUMENT-END
// STREAM-END
//
// 3. Several documents in a stream:
//
// 'a scalar'
// ---
// 'another scalar'
// ---
// 'yet another scalar'
//
// Tokens:
//
// STREAM-START(utf-8)
// SCALAR("a scalar",single-quoted)
// DOCUMENT-START
// SCALAR("another scalar",single-quoted)
// DOCUMENT-START
// SCALAR("yet another scalar",single-quoted)
// STREAM-END
//
// We have already introduced the SCALAR token above. The following tokens are
// used to describe aliases, anchors, tag, and scalars:
//
// ALIAS(anchor)
// ANCHOR(anchor)
// TAG(handle,suffix)
// SCALAR(value,style)
//
// The following series of examples illustrate the usage of these tokens:
//
// 1. A recursive sequence:
//
// &A [ *A ]
//
// Tokens:
//
// STREAM-START(utf-8)
// ANCHOR("A")
// FLOW-SEQUENCE-START
// ALIAS("A")
// FLOW-SEQUENCE-END
// STREAM-END
//
// 2. A tagged scalar:
//
// !!float "3.14" # A good approximation.
//
// Tokens:
//
// STREAM-START(utf-8)
// TAG("!!","float")
// SCALAR("3.14",double-quoted)
// STREAM-END
//
// 3. Various scalar styles:
//
// --- # Implicit empty plain scalars do not produce tokens.
// --- a plain scalar
// --- 'a single-quoted scalar'
// --- "a double-quoted scalar"
// --- |-
// a literal scalar
// --- >-
// a folded
// scalar
//
// Tokens:
//
// STREAM-START(utf-8)
// DOCUMENT-START
// DOCUMENT-START
// SCALAR("a plain scalar",plain)
// DOCUMENT-START
// SCALAR("a single-quoted scalar",single-quoted)
// DOCUMENT-START
// SCALAR("a double-quoted scalar",double-quoted)
// DOCUMENT-START
// SCALAR("a literal scalar",literal)
// DOCUMENT-START
// SCALAR("a folded scalar",folded)
// STREAM-END
//
// Now it's time to review collection-related tokens. We will start with
// flow collections:
//
// FLOW-SEQUENCE-START
// FLOW-SEQUENCE-END
// FLOW-MAPPING-START
// FLOW-MAPPING-END
// FLOW-ENTRY
// KEY
// VALUE
//
// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
// correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the
// indicators '?' and ':', which are used for denoting mapping keys and values,
// are represented by the KEY and VALUE tokens.
//
// The following examples show flow collections:
//
// 1. A flow sequence:
//
// [item 1, item 2, item 3]
//
// Tokens:
//
// STREAM-START(utf-8)
// FLOW-SEQUENCE-START
// SCALAR("item 1",plain)
// FLOW-ENTRY
// SCALAR("item 2",plain)
// FLOW-ENTRY
// SCALAR("item 3",plain)
// FLOW-SEQUENCE-END
// STREAM-END
//
// 2. A flow mapping:
//
// {
// a simple key: a value, # Note that the KEY token is produced.
// ? a complex key: another value,
// }
//
// Tokens:
//
// STREAM-START(utf-8)
// FLOW-MAPPING-START
// KEY
// SCALAR("a simple key",plain)
// VALUE
// SCALAR("a value",plain)
// FLOW-ENTRY
// KEY
// SCALAR("a complex key",plain)
// VALUE
// SCALAR("another value",plain)
// FLOW-ENTRY
// FLOW-MAPPING-END
// STREAM-END
//
// A simple key is a key which is not denoted by the '?' indicator. Note that
// the Scanner still produce the KEY token whenever it encounters a simple key.
//
// For scanning block collections, the following tokens are used (note that we
// repeat KEY and VALUE here):
//
// BLOCK-SEQUENCE-START
// BLOCK-MAPPING-START
// BLOCK-END
// BLOCK-ENTRY
// KEY
// VALUE
//
// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
// increase that precedes a block collection (cf. the INDENT token in Python).
// The token BLOCK-END denote indentation decrease that ends a block collection
// (cf. the DEDENT token in Python). However YAML has some syntax pecularities
// that makes detections of these tokens more complex.
//
// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
// '-', '?', and ':' correspondingly.
//
// The following examples show how the tokens BLOCK-SEQUENCE-START,
// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
//
// 1. Block sequences:
//
// - item 1
// - item 2
// -
// - item 3.1
// - item 3.2
// -
// key 1: value 1
// key 2: value 2
//
// Tokens:
//
// STREAM-START(utf-8)
// BLOCK-SEQUENCE-START
// BLOCK-ENTRY
// SCALAR("item 1",plain)
// BLOCK-ENTRY
// SCALAR("item 2",plain)
// BLOCK-ENTRY
// BLOCK-SEQUENCE-START
// BLOCK-ENTRY
// SCALAR("item 3.1",plain)
// BLOCK-ENTRY
// SCALAR("item 3.2",plain)
// BLOCK-END
// BLOCK-ENTRY
// BLOCK-MAPPING-START
// KEY
// SCALAR("key 1",plain)
// VALUE
// SCALAR("value 1",plain)
// KEY
// SCALAR("key 2",plain)
// VALUE
// SCALAR("value 2",plain)
// BLOCK-END
// BLOCK-END
// STREAM-END
//
// 2. Block mappings:
//
// a simple key: a value # The KEY token is produced here.
// ? a complex key
// : another value
// a mapping:
// key 1: value 1
// key 2: value 2
// a sequence:
// - item 1
// - item 2
//
// Tokens:
//
// STREAM-START(utf-8)
// BLOCK-MAPPING-START
// KEY
// SCALAR("a simple key",plain)
// VALUE
// SCALAR("a value",plain)
// KEY
// SCALAR("a complex key",plain)
// VALUE
// SCALAR("another value",plain)
// KEY
// SCALAR("a mapping",plain)
// BLOCK-MAPPING-START
// KEY
// SCALAR("key 1",plain)
// VALUE
// SCALAR("value 1",plain)
// KEY
// SCALAR("key 2",plain)
// VALUE
// SCALAR("value 2",plain)
// BLOCK-END
// KEY
// SCALAR("a sequence",plain)
// VALUE
// BLOCK-SEQUENCE-START
// BLOCK-ENTRY
// SCALAR("item 1",plain)
// BLOCK-ENTRY
// SCALAR("item 2",plain)
// BLOCK-END
// BLOCK-END
// STREAM-END
//
// YAML does not always require to start a new block collection from a new
// line. If the current line contains only '-', '?', and ':' indicators, a new
// block collection may start at the current line. The following examples
// illustrate this case:
//
// 1. Collections in a sequence:
//
// - - item 1
// - item 2
// - key 1: value 1
// key 2: value 2
// - ? complex key
// : complex value
//
// Tokens:
//
// STREAM-START(utf-8)
// BLOCK-SEQUENCE-START
// BLOCK-ENTRY
// BLOCK-SEQUENCE-START
// BLOCK-ENTRY
// SCALAR("item 1",plain)
// BLOCK-ENTRY
// SCALAR("item 2",plain)
// BLOCK-END
// BLOCK-ENTRY
// BLOCK-MAPPING-START
// KEY
// SCALAR("key 1",plain)
// VALUE
// SCALAR("value 1",plain)
// KEY
// SCALAR("key 2",plain)
// VALUE
// SCALAR("value 2",plain)
// BLOCK-END
// BLOCK-ENTRY
// BLOCK-MAPPING-START
// KEY
// SCALAR("complex key")
// VALUE
// SCALAR("complex value")
// BLOCK-END
// BLOCK-END
// STREAM-END
//
// 2. Collections in a mapping:
//
// ? a sequence
// : - item 1
// - item 2
// ? a mapping
// : key 1: value 1
// key 2: value 2
//
// Tokens:
//
// STREAM-START(utf-8)
// BLOCK-MAPPING-START
// KEY
// SCALAR("a sequence",plain)
// VALUE
// BLOCK-SEQUENCE-START
// BLOCK-ENTRY
// SCALAR("item 1",plain)
// BLOCK-ENTRY
// SCALAR("item 2",plain)
// BLOCK-END
// KEY
// SCALAR("a mapping",plain)
// VALUE
// BLOCK-MAPPING-START
// KEY
// SCALAR("key 1",plain)
// VALUE
// SCALAR("value 1",plain)
// KEY
// SCALAR("key 2",plain)
// VALUE
// SCALAR("value 2",plain)
// BLOCK-END
// BLOCK-END
// STREAM-END
//
// YAML also permits non-indented sequences if they are included into a block
// mapping. In this case, the token BLOCK-SEQUENCE-START is not produced:
//
// key:
// - item 1 # BLOCK-SEQUENCE-START is NOT produced here.
// - item 2
//
// Tokens:
//
// STREAM-START(utf-8)
// BLOCK-MAPPING-START
// KEY
// SCALAR("key",plain)
// VALUE
// BLOCK-ENTRY
// SCALAR("item 1",plain)
// BLOCK-ENTRY
// SCALAR("item 2",plain)
// BLOCK-END
//

# Go example projects
[![Go Reference](https://pkg.go.dev/badge/golang.org/x/example.svg)](https://pkg.go.dev/golang.org/x/example)
This repository contains a collection of Go programs and libraries that
demonstrate the language, standard libraries, and tools.
## Clone the project
```
$ git clone https://go.googlesource.com/example
$ cd example
```
https://go.googlesource.com/example is the canonical Git repository.
It is mirrored at https://github.com/golang/example.
## [hello](hello/) and [hello/reverse](hello/reverse/)
```
$ cd hello
$ go build
$ ./hello -help
```
A trivial "Hello, world" program that uses a library package.
The [hello](hello/) command covers:
* The basic form of an executable command
* Importing packages (from the standard library and the local repository)
* Printing strings ([fmt](//golang.org/pkg/fmt/))
* Command-line flags ([flag](//golang.org/pkg/flag/))
* Logging ([log](//golang.org/pkg/log/))
The [reverse](hello/reverse/) reverse covers:
* The basic form of a library
* Conversion between string and []rune
* Table-driven unit tests ([testing](//golang.org/pkg/testing/))
## [helloserver](helloserver/)
```
$ cd helloserver
$ go run .
```
A trivial "Hello, world" web server.
Topics covered:
* Command-line flags ([flag](//golang.org/pkg/flag/))
* Logging ([log](//golang.org/pkg/log/))
* Web servers ([net/http](//golang.org/pkg/net/http/))
## [outyet](outyet/)
```
$ cd outyet
$ go run .
```
A web server that answers the question: "Is Go 1.x out yet?"
Topics covered:
* Command-line flags ([flag](//golang.org/pkg/flag/))
* Web servers ([net/http](//golang.org/pkg/net/http/))
* HTML Templates ([html/template](//golang.org/pkg/html/template/))
* Logging ([log](//golang.org/pkg/log/))
* Long-running background processes
* Synchronizing data access between goroutines ([sync](//golang.org/pkg/sync/))
* Exporting server state for monitoring ([expvar](//golang.org/pkg/expvar/))
* Unit and integration tests ([testing](//golang.org/pkg/testing/))
* Dependency injection
* Time ([time](//golang.org/pkg/time/))
## [appengine-hello](appengine-hello/)
A trivial "Hello, world" App Engine application intended to be used as the
starting point for your own code. Please see
[Google App Engine SDK for Go](https://cloud.google.com/appengine/downloads#Google_App_Engine_SDK_for_Go)
and [Quickstart for Go in the App Engine Standard Environment](https://cloud.google.com/appengine/docs/standard/go/quickstart).
## [gotypes](gotypes/)
The `go/types` package is a type-checker for Go programs. It is one of the most
complex packages in Go's standard library, so we have provided this tutorial to
help you find your bearings. It comes with several example programs that you
can obtain using `go get` and play with as you learn to build tools that analyze
or manipulate Go programs.
## [template](template/)
A trivial web server that demonstrates the use of the
[`template` package](https://golang.org/pkg/text/template/)'s `block` feature.
## [slog-handler-guide](slog-handler-guide/)
The `log/slog` package supports structured logging.
It features a flexible backend in the form of a `Handler` interface.
This guide can help you write your own handler.

Vendoring in std and cmd
========================
The Go command maintains copies of external packages needed by the
standard library in the src/vendor and src/cmd/vendor directories.
There are two modules, std and cmd, defined in src/go.mod and
src/cmd/go.mod. When a package outside std or cmd is imported
by a package inside std or cmd, the import path is interpreted
as if it had a "vendor/" prefix. For example, within "crypto/tls",
an import of "golang.org/x/crypto/cryptobyte" resolves to
"vendor/golang.org/x/crypto/cryptobyte". When a package with the
same path is imported from a package outside std or cmd, it will
be resolved normally. Consequently, a binary may be built with two
copies of a package at different versions if the package is
imported normally and vendored by the standard library.
Vendored packages are internally renamed with a "vendor/" prefix
to preserve the invariant that all packages have distinct paths.
This is necessary to avoid compiler and linker conflicts. Adding
a "vendor/" prefix also maintains the invariant that standard
library packages begin with a dotless path element.
The module requirements of std and cmd do not influence version
selection in other modules. They are only considered when running
module commands like 'go get' and 'go mod vendor' from a directory
in GOROOT/src.
Maintaining vendor directories
==============================
Before updating vendor directories, ensure that module mode is enabled.
Make sure that GO111MODULE is not set in the environment, or that it is
set to 'on' or 'auto', and if you use a go.work file, set GOWORK=off.
Requirements may be added, updated, and removed with 'go get'.
The vendor directory may be updated with 'go mod vendor'.
A typical sequence might be:
cd src # or src/cmd
go get golang.org/x/net@master
go mod tidy
go mod vendor
Use caution when passing '-u' to 'go get'. The '-u' flag updates
modules providing all transitively imported packages, not only
the module providing the target package.
Note that 'go mod vendor' only copies packages that are transitively
imported by packages in the current module. If a new package is needed,
it should be imported before running 'go mod vendor'.

// Scanning stops if the function returns an error, in which case some of
// the input may be discarded. If that error is [ErrFinalToken], scanning

// yet hold a complete token, for instance if it has no newline while

Cgo enables the creation of Go packages that call C code.
# Using cgo with the go command
To use cgo write normal Go code that imports a pseudo-package "C".
The Go code can then refer to types such as C.size_t, variables such
as C.stdout, or functions such as C.putchar.
If the import of "C" is immediately preceded by a comment, that
comment, called the preamble, is used as a header when compiling
the C parts of the package. For example:
// #include <stdio.h>
// #include <errno.h>
import "C"
The preamble may contain any C code, including function and variable
declarations and definitions. These may then be referred to from Go
code as though they were defined in the package "C". All names
declared in the preamble may be used, even if they start with a
lower-case letter. Exception: static variables in the preamble may
not be referenced from Go code; static functions are permitted.
See $GOROOT/cmd/cgo/internal/teststdio and $GOROOT/misc/cgo/gmp for examples. See
"C? Go? Cgo!" for an introduction to using cgo:
https://golang.org/doc/articles/c_go_cgo.html.
CFLAGS, CPPFLAGS, CXXFLAGS, FFLAGS and LDFLAGS may be defined with pseudo
#cgo directives within these comments to tweak the behavior of the C, C++
or Fortran compiler. Values defined in multiple directives are concatenated
together. The directive can include a list of build constraints limiting its
effect to systems satisfying one of the constraints
(see https://golang.org/pkg/go/build/#hdr-Build_Constraints for details about the constraint syntax).
For example:
// #cgo CFLAGS: -DPNG_DEBUG=1
// #cgo amd64 386 CFLAGS: -DX86=1
// #cgo LDFLAGS: -lpng
// #include <png.h>
import "C"
Alternatively, CPPFLAGS and LDFLAGS may be obtained via the pkg-config tool
using a '#cgo pkg-config:' directive followed by the package names.
For example:
// #cgo pkg-config: png cairo
// #include <png.h>
import "C"
The default pkg-config tool may be changed by setting the PKG_CONFIG environment variable.
For security reasons, only a limited set of flags are allowed, notably -D, -U, -I, and -l.
To allow additional flags, set CGO_CFLAGS_ALLOW to a regular expression
matching the new flags. To disallow flags that would otherwise be allowed,
set CGO_CFLAGS_DISALLOW to a regular expression matching arguments
that must be disallowed. In both cases the regular expression must match
a full argument: to allow -mfoo=bar, use CGO_CFLAGS_ALLOW='-mfoo.*',
not just CGO_CFLAGS_ALLOW='-mfoo'. Similarly named variables control
the allowed CPPFLAGS, CXXFLAGS, FFLAGS, and LDFLAGS.
Also for security reasons, only a limited set of characters are
permitted, notably alphanumeric characters and a few symbols, such as
'.', that will not be interpreted in unexpected ways. Attempts to use
forbidden characters will get a "malformed #cgo argument" error.
When building, the CGO_CFLAGS, CGO_CPPFLAGS, CGO_CXXFLAGS, CGO_FFLAGS and
CGO_LDFLAGS environment variables are added to the flags derived from
these directives. Package-specific flags should be set using the
directives, not the environment variables, so that builds work in
unmodified environments. Flags obtained from environment variables
are not subject to the security limitations described above.
All the cgo CPPFLAGS and CFLAGS directives in a package are concatenated and
used to compile C files in that package. All the CPPFLAGS and CXXFLAGS
directives in a package are concatenated and used to compile C++ files in that
package. All the CPPFLAGS and FFLAGS directives in a package are concatenated
and used to compile Fortran files in that package. All the LDFLAGS directives
in any package in the program are concatenated and used at link time. All the
pkg-config directives are concatenated and sent to pkg-config simultaneously
to add to each appropriate set of command-line flags.
When the cgo directives are parsed, any occurrence of the string ${SRCDIR}
will be replaced by the absolute path to the directory containing the source
file. This allows pre-compiled static libraries to be included in the package
directory and linked properly.
For example if package foo is in the directory /go/src/foo:
// #cgo LDFLAGS: -L${SRCDIR}/libs -lfoo
Will be expanded to:
// #cgo LDFLAGS: -L/go/src/foo/libs -lfoo
When the Go tool sees that one or more Go files use the special import
"C", it will look for other non-Go files in the directory and compile
them as part of the Go package. Any .c, .s, .S or .sx files will be
compiled with the C compiler. Any .cc, .cpp, or .cxx files will be
compiled with the C++ compiler. Any .f, .F, .for or .f90 files will be
compiled with the fortran compiler. Any .h, .hh, .hpp, or .hxx files will
not be compiled separately, but, if these header files are changed,
the package (including its non-Go source files) will be recompiled.
Note that changes to files in other directories do not cause the package
to be recompiled, so all non-Go source code for the package should be
stored in the package directory, not in subdirectories.
The default C and C++ compilers may be changed by the CC and CXX
environment variables, respectively; those environment variables
may include command line options.
The cgo tool will always invoke the C compiler with the source file's
directory in the include path; i.e. -I${SRCDIR} is always implied. This
means that if a header file foo/bar.h exists both in the source
directory and also in the system include directory (or some other place
specified by a -I flag), then "#include <foo/bar.h>" will always find the
local version in preference to any other version.
The cgo tool is enabled by default for native builds on systems where
it is expected to work. It is disabled by default when cross-compiling
as well as when the CC environment variable is unset and the default
C compiler (typically gcc or clang) cannot be found on the system PATH.
You can override the default by setting the CGO_ENABLED
environment variable when running the go tool: set it to 1 to enable
the use of cgo, and to 0 to disable it. The go tool will set the
build constraint "cgo" if cgo is enabled. The special import "C"
implies the "cgo" build constraint, as though the file also said
"//go:build cgo". Therefore, if cgo is disabled, files that import
"C" will not be built by the go tool. (For more about build constraints
see https://golang.org/pkg/go/build/#hdr-Build_Constraints).
When cross-compiling, you must specify a C cross-compiler for cgo to
use. You can do this by setting the generic CC_FOR_TARGET or the
more specific CC_FOR_${GOOS}_${GOARCH} (for example, CC_FOR_linux_arm)
environment variable when building the toolchain using make.bash,
or you can set the CC environment variable any time you run the go tool.
The CXX_FOR_TARGET, CXX_FOR_${GOOS}_${GOARCH}, and CXX
environment variables work in a similar way for C++ code.
# Go references to C
Within the Go file, C's struct field names that are keywords in Go
can be accessed by prefixing them with an underscore: if x points at a C
struct with a field named "type", x._type accesses the field.
C struct fields that cannot be expressed in Go, such as bit fields
or misaligned data, are omitted in the Go struct, replaced by
appropriate padding to reach the next field or the end of the struct.
The standard C numeric types are available under the names
C.char, C.schar (signed char), C.uchar (unsigned char),
C.short, C.ushort (unsigned short), C.int, C.uint (unsigned int),
C.long, C.ulong (unsigned long), C.longlong (long long),
C.ulonglong (unsigned long long), C.float, C.double,
C.complexfloat (complex float), and C.complexdouble (complex double).
The C type void* is represented by Go's unsafe.Pointer.
The C types __int128_t and __uint128_t are represented by [16]byte.
A few special C types which would normally be represented by a pointer
type in Go are instead represented by a uintptr. See the Special
cases section below.
To access a struct, union, or enum type directly, prefix it with
struct_, union_, or enum_, as in C.struct_stat.
The size of any C type T is available as C.sizeof_T, as in
C.sizeof_struct_stat.
A C function may be declared in the Go file with a parameter type of
the special name _GoString_. This function may be called with an
ordinary Go string value. The string length, and a pointer to the
string contents, may be accessed by calling the C functions
size_t _GoStringLen(_GoString_ s);
const char *_GoStringPtr(_GoString_ s);
These functions are only available in the preamble, not in other C
files. The C code must not modify the contents of the pointer returned
by _GoStringPtr. Note that the string contents may not have a trailing
NUL byte.
As Go doesn't have support for C's union type in the general case,
C's union types are represented as a Go byte array with the same length.
Go structs cannot embed fields with C types.
Go code cannot refer to zero-sized fields that occur at the end of
non-empty C structs. To get the address of such a field (which is the
only operation you can do with a zero-sized field) you must take the
address of the struct and add the size of the struct.
Cgo translates C types into equivalent unexported Go types.
Because the translations are unexported, a Go package should not
expose C types in its exported API: a C type used in one Go package
is different from the same C type used in another.
Any C function (even void functions) may be called in a multiple
assignment context to retrieve both the return value (if any) and the
C errno variable as an error (use _ to skip the result value if the
function returns void). For example:
n, err = C.sqrt(-1)
_, err := C.voidFunc()
var n, err = C.sqrt(1)
Calling C function pointers is currently not supported, however you can
declare Go variables which hold C function pointers and pass them
back and forth between Go and C. C code may call function pointers
received from Go. For example:
package main
// typedef int (*intFunc) ();
//
// int
// bridge_int_func(intFunc f)
// {
// return f();
// }
//
// int fortytwo()
// {
// return 42;
// }
import "C"
import "fmt"
func main() {
f := C.intFunc(C.fortytwo)
fmt.Println(int(C.bridge_int_func(f)))
// Output: 42
}
In C, a function argument written as a fixed size array
actually requires a pointer to the first element of the array.
C compilers are aware of this calling convention and adjust
the call accordingly, but Go cannot. In Go, you must pass
the pointer to the first element explicitly: C.f(&C.x[0]).
Calling variadic C functions is not supported. It is possible to
circumvent this by using a C function wrapper. For example:
package main
// #include <stdio.h>
// #include <stdlib.h>
//
// static void myprint(char* s) {
// printf("%s\n", s);
// }
import "C"
import "unsafe"
func main() {
cs := C.CString("Hello from stdio")
C.myprint(cs)
C.free(unsafe.Pointer(cs))
}
A few special functions convert between Go and C types
by making copies of the data. In pseudo-Go definitions:
// Go string to C string
// The C string is allocated in the C heap using malloc.
// It is the caller's responsibility to arrange for it to be
// freed, such as by calling C.free (be sure to include stdlib.h
// if C.free is needed).
func C.CString(string) *C.char
// Go []byte slice to C array
// The C array is allocated in the C heap using malloc.
// It is the caller's responsibility to arrange for it to be
// freed, such as by calling C.free (be sure to include stdlib.h
// if C.free is needed).
func C.CBytes([]byte) unsafe.Pointer
// C string to Go string
func C.GoString(*C.char) string
// C data with explicit length to Go string
func C.GoStringN(*C.char, C.int) string
// C data with explicit length to Go []byte
func C.GoBytes(unsafe.Pointer, C.int) []byte
As a special case, C.malloc does not call the C library malloc directly
but instead calls a Go helper function that wraps the C library malloc
but guarantees never to return nil. If C's malloc indicates out of memory,
the helper function crashes the program, like when Go itself runs out
of memory. Because C.malloc cannot fail, it has no two-result form
that returns errno.
# C references to Go
Go functions can be exported for use by C code in the following way:
//export MyFunction
func MyFunction(arg1, arg2 int, arg3 string) int64 {...}
//export MyFunction2
func MyFunction2(arg1, arg2 int, arg3 string) (int64, *C.char) {...}
They will be available in the C code as:
extern GoInt64 MyFunction(int arg1, int arg2, GoString arg3);
extern struct MyFunction2_return MyFunction2(int arg1, int arg2, GoString arg3);
found in the _cgo_export.h generated header, after any preambles
copied from the cgo input files. Functions with multiple
return values are mapped to functions returning a struct.
Not all Go types can be mapped to C types in a useful way.
Go struct types are not supported; use a C struct type.
Go array types are not supported; use a C pointer.
Go functions that take arguments of type string may be called with the
C type _GoString_, described above. The _GoString_ type will be
automatically defined in the preamble. Note that there is no way for C
code to create a value of this type; this is only useful for passing
string values from Go to C and back to Go.
Using //export in a file places a restriction on the preamble:
since it is copied into two different C output files, it must not
contain any definitions, only declarations. If a file contains both
definitions and declarations, then the two output files will produce
duplicate symbols and the linker will fail. To avoid this, definitions
must be placed in preambles in other files, or in C source files.
# Passing pointers
Go is a garbage collected language, and the garbage collector needs to
know the location of every pointer to Go memory. Because of this,
there are restrictions on passing pointers between Go and C.
In this section the term Go pointer means a pointer to memory
allocated by Go (such as by using the & operator or calling the
predefined new function) and the term C pointer means a pointer to
memory allocated by C (such as by a call to C.malloc). Whether a
pointer is a Go pointer or a C pointer is a dynamic property
determined by how the memory was allocated; it has nothing to do with
the type of the pointer.
Note that values of some Go types, other than the type's zero value,
always include Go pointers. This is true of string, slice, interface,
channel, map, and function types. A pointer type may hold a Go pointer
or a C pointer. Array and struct types may or may not include Go
pointers, depending on the element types. All the discussion below
about Go pointers applies not just to pointer types, but also to other
types that include Go pointers.
All Go pointers passed to C must point to pinned Go memory. Go pointers
passed as function arguments to C functions have the memory they point to
implicitly pinned for the duration of the call. Go memory reachable from
these function arguments must be pinned as long as the C code has access
to it. Whether Go memory is pinned is a dynamic property of that memory
region; it has nothing to do with the type of the pointer.
Go values created by calling new, by taking the address of a composite
literal, or by taking the address of a local variable may also have their
memory pinned using [runtime.Pinner]. This type may be used to manage
the duration of the memory's pinned status, potentially beyond the
duration of a C function call. Memory may be pinned more than once and
must be unpinned exactly the same number of times it has been pinned.
Go code may pass a Go pointer to C provided the memory to which it
points does not contain any Go pointers to memory that is unpinned. When
passing a pointer to a field in a struct, the Go memory in question is
the memory occupied by the field, not the entire struct. When passing a
pointer to an element in an array or slice, the Go memory in question is
the entire array or the entire backing array of the slice.
C code may keep a copy of a Go pointer only as long as the memory it
points to is pinned.
C code may not keep a copy of a Go pointer after the call returns,
unless the memory it points to is pinned with [runtime.Pinner] and the
Pinner is not unpinned while the Go pointer is stored in C memory.
This implies that C code may not keep a copy of a string, slice,
channel, and so forth, because they cannot be pinned with
[runtime.Pinner].
The _GoString_ type also may not be pinned with [runtime.Pinner].
Because it includes a Go pointer, the memory it points to is only pinned
for the duration of the call; _GoString_ values may not be retained by C
code.
A Go function called by C code may return a Go pointer to pinned memory
(which implies that it may not return a string, slice, channel, and so
forth). A Go function called by C code may take C pointers as arguments,
and it may store non-pointer data, C pointers, or Go pointers to pinned
memory through those pointers. It may not store a Go pointer to unpinned
memory in memory pointed to by a C pointer (which again, implies that it
may not store a string, slice, channel, and so forth). A Go function
called by C code may take a Go pointer but it must preserve the property
that the Go memory to which it points (and the Go memory to which that
memory points, and so on) is pinned.
These rules are checked dynamically at runtime. The checking is
controlled by the cgocheck setting of the GODEBUG environment
variable. The default setting is GODEBUG=cgocheck=1, which implements
reasonably cheap dynamic checks. These checks may be disabled
entirely using GODEBUG=cgocheck=0. Complete checking of pointer
handling, at some cost in run time, is available by setting
GOEXPERIMENT=cgocheck2 at build time.
It is possible to defeat this enforcement by using the unsafe package,
and of course there is nothing stopping the C code from doing anything
it likes. However, programs that break these rules are likely to fail
in unexpected and unpredictable ways.
The runtime/cgo.Handle type can be used to safely pass Go values
between Go and C. See the runtime/cgo package documentation for details.
Note: the current implementation has a bug. While Go code is permitted
to write nil or a C pointer (but not a Go pointer) to C memory, the
current implementation may sometimes cause a runtime error if the
contents of the C memory appear to be a Go pointer. Therefore, avoid
passing uninitialized C memory to Go code if the Go code is going to
store pointer values in it. Zero out the memory in C before passing it
to Go.
# Special cases
A few special C types which would normally be represented by a pointer
type in Go are instead represented by a uintptr. Those include:
1. The *Ref types on Darwin, rooted at CoreFoundation's CFTypeRef type.
2. The object types from Java's JNI interface:
jobject
jclass
jthrowable
jstring
jarray
jbooleanArray
jbyteArray
jcharArray
jshortArray
jintArray
jlongArray
jfloatArray
jdoubleArray
jobjectArray
jweak
3. The EGLDisplay and EGLConfig types from the EGL API.
These types are uintptr on the Go side because they would otherwise
confuse the Go garbage collector; they are sometimes not really
pointers but data structures encoded in a pointer type. All operations
on these types must happen in C. The proper constant to initialize an
empty such reference is 0, not nil.
These special cases were introduced in Go 1.10. For auto-updating code
from Go 1.9 and earlier, use the cftype or jni rewrites in the Go fix tool:
go tool fix -r cftype <pkg>
go tool fix -r jni <pkg>
It will replace nil with 0 in the appropriate places.
The EGLDisplay case was introduced in Go 1.12. Use the egl rewrite
to auto-update code from Go 1.11 and earlier:
go tool fix -r egl <pkg>
The EGLConfig case was introduced in Go 1.15. Use the eglconf rewrite
to auto-update code from Go 1.14 and earlier:
go tool fix -r eglconf <pkg>
# Using cgo directly
Usage:
go tool cgo [cgo options] [-- compiler options] gofiles...
Cgo transforms the specified input Go source files into several output
Go and C source files.
The compiler options are passed through uninterpreted when
invoking the C compiler to compile the C parts of the package.
The following options are available when running cgo directly:
-V
Print cgo version and exit.
-debug-define
Debugging option. Print #defines.
-debug-gcc
Debugging option. Trace C compiler execution and output.
-dynimport file
Write list of symbols imported by file. Write to
-dynout argument or to standard output. Used by go
build when building a cgo package.
-dynlinker
Write dynamic linker as part of -dynimport output.
-dynout file
Write -dynimport output to file.
-dynpackage package
Set Go package for -dynimport output.
-exportheader file
If there are any exported functions, write the
generated export declarations to file.
C code can #include this to see the declarations.
-importpath string
The import path for the Go package. Optional; used for
nicer comments in the generated files.
-import_runtime_cgo
If set (which it is by default) import runtime/cgo in
generated output.
-import_syscall
If set (which it is by default) import syscall in
generated output.
-gccgo
Generate output for the gccgo compiler rather than the
gc compiler.
-gccgoprefix prefix
The -fgo-prefix option to be used with gccgo.
-gccgopkgpath path
The -fgo-pkgpath option to be used with gccgo.
-gccgo_define_cgoincomplete
Define cgo.Incomplete locally rather than importing it from
the "runtime/cgo" package. Used for old gccgo versions.
-godefs
Write out input file in Go syntax replacing C package
names with real values. Used to generate files in the
syscall package when bootstrapping a new target.
-ldflags flags
Flags to pass to the C linker. The cmd/go tool uses
this to pass in the flags in the CGO_LDFLAGS variable.
-objdir directory
Put all generated files in directory.
-srcdir directory

/*
Implementation details.
Cgo provides a way for Go programs to call C code linked into the same
address space. This comment explains the operation of cgo.
Cgo reads a set of Go source files and looks for statements saying
import "C". If the import has a doc comment, that comment is
taken as literal C code to be used as a preamble to any C code
generated by cgo. A typical preamble #includes necessary definitions:
// #include <stdio.h>
import "C"
For more details about the usage of cgo, see the documentation
comment at the top of this file.
Understanding C
Cgo scans the Go source files that import "C" for uses of that
package, such as C.puts. It collects all such identifiers. The next
step is to determine each kind of name. In C.xxx the xxx might refer
to a type, a function, a constant, or a global variable. Cgo must
decide which.
The obvious thing for cgo to do is to process the preamble, expanding
#includes and processing the corresponding C code. That would require
a full C parser and type checker that was also aware of any extensions
known to the system compiler (for example, all the GNU C extensions) as
well as the system-specific header locations and system-specific
pre-#defined macros. This is certainly possible to do, but it is an
enormous amount of work.
Cgo takes a different approach. It determines the meaning of C
identifiers not by parsing C code but by feeding carefully constructed
programs into the system C compiler and interpreting the generated
error messages, debug information, and object files. In practice,
parsing these is significantly less work and more robust than parsing
C source.
Cgo first invokes gcc -E -dM on the preamble, in order to find out
about simple #defines for constants and the like. These are recorded
for later use.
Next, cgo needs to identify the kinds for each identifier. For the
identifiers C.foo, cgo generates this C program:
<preamble>
#line 1 "not-declared"
void __cgo_f_1_1(void) { __typeof__(foo) *__cgo_undefined__1; }
#line 1 "not-type"
void __cgo_f_1_2(void) { foo *__cgo_undefined__2; }
#line 1 "not-int-const"
void __cgo_f_1_3(void) { enum { __cgo_undefined__3 = (foo)*1 }; }
#line 1 "not-num-const"
void __cgo_f_1_4(void) { static const double __cgo_undefined__4 = (foo); }
#line 1 "not-str-lit"
void __cgo_f_1_5(void) { static const char __cgo_undefined__5[] = (foo); }
This program will not compile, but cgo can use the presence or absence
of an error message on a given line to deduce the information it
needs. The program is syntactically valid regardless of whether each
name is a type or an ordinary identifier, so there will be no syntax
errors that might stop parsing early.
An error on not-declared:1 indicates that foo is undeclared.
An error on not-type:1 indicates that foo is not a type (if declared at all, it is an identifier).
An error on not-int-const:1 indicates that foo is not an integer constant.
An error on not-num-const:1 indicates that foo is not a number constant.
An error on not-str-lit:1 indicates that foo is not a string literal.
An error on not-signed-int-const:1 indicates that foo is not a signed integer constant.
The line number specifies the name involved. In the example, 1 is foo.
Next, cgo must learn the details of each type, variable, function, or
constant. It can do this by reading object files. If cgo has decided
that t1 is a type, v2 and v3 are variables or functions, and i4, i5
are integer constants, u6 is an unsigned integer constant, and f7 and f8
are float constants, and s9 and s10 are string constants, it generates:
<preamble>
__typeof__(t1) *__cgo__1;
__typeof__(v2) *__cgo__2;
__typeof__(v3) *__cgo__3;
__typeof__(i4) *__cgo__4;
enum { __cgo_enum__4 = i4 };
__typeof__(i5) *__cgo__5;
enum { __cgo_enum__5 = i5 };
__typeof__(u6) *__cgo__6;
enum { __cgo_enum__6 = u6 };
__typeof__(f7) *__cgo__7;
__typeof__(f8) *__cgo__8;
__typeof__(s9) *__cgo__9;
__typeof__(s10) *__cgo__10;
long long __cgodebug_ints[] = {

const char __cgodebug_str__9[] = s9;

const char __cgodebug_str__10[] = s10;
const unsigned long long __cgodebug_strlen__10 = sizeof(s10)-1;
and again invokes the system C compiler, to produce an object file
containing debug information. Cgo parses the DWARF debug information
for __cgo__N to learn the type of each identifier. (The types also
distinguish functions from global variables.) Cgo reads the constant
values from the __cgodebug_* from the object file's data segment.
At this point cgo knows the meaning of each C.xxx well enough to start
the translation process.
Translating Go
Given the input Go files x.go and y.go, cgo generates these source
files:
x.cgo1.go # for gc (cmd/compile)
y.cgo1.go # for gc
_cgo_gotypes.go # for gc
_cgo_import.go # for gc (if -dynout _cgo_import.go)
x.cgo2.c # for gcc
y.cgo2.c # for gcc
_cgo_defun.c # for gcc (if -gccgo)
_cgo_export.c # for gcc
_cgo_export.h # for gcc
_cgo_main.c # for gcc
_cgo_flags # for build tool (if -gccgo)
The file x.cgo1.go is a copy of x.go with the import "C" removed and
references to C.xxx replaced with names like _Cfunc_xxx or _Ctype_xxx.
The definitions of those identifiers, written as Go functions, types,
or variables, are provided in _cgo_gotypes.go.
Here is a _cgo_gotypes.go containing definitions for needed C types:
type _Ctype_char int8
type _Ctype_int int32
type _Ctype_void [0]byte
The _cgo_gotypes.go file also contains the definitions of the
functions. They all have similar bodies that invoke runtime·cgocall
to make a switch from the Go runtime world to the system C (GCC-based)
world.
For example, here is the definition of _Cfunc_puts:
//go:cgo_import_static _cgo_be59f0f25121_Cfunc_puts
//go:linkname __cgofn__cgo_be59f0f25121_Cfunc_puts _cgo_be59f0f25121_Cfunc_puts
var __cgofn__cgo_be59f0f25121_Cfunc_puts byte
var _cgo_be59f0f25121_Cfunc_puts = unsafe.Pointer(&__cgofn__cgo_be59f0f25121_Cfunc_puts)
func _Cfunc_puts(p0 *_Ctype_char) (r1 _Ctype_int) {
_cgo_runtime_cgocall(_cgo_be59f0f25121_Cfunc_puts, uintptr(unsafe.Pointer(&p0)))
return
}
The hexadecimal number is a hash of cgo's input, chosen to be
deterministic yet unlikely to collide with other uses. The actual
function _cgo_be59f0f25121_Cfunc_puts is implemented in a C source
file compiled by gcc, the file x.cgo2.c:
void
_cgo_be59f0f25121_Cfunc_puts(void *v)
{
struct {
char* p0;
int r;
char __pad12[4];
} __attribute__((__packed__, __gcc_struct__)) *a = v;
a->r = puts((void*)a->p0);
}
It extracts the arguments from the pointer to _Cfunc_puts's argument
frame, invokes the system C function (in this case, puts), stores the
result in the frame, and returns.
Linking
Once the _cgo_export.c and *.cgo2.c files have been compiled with gcc,
they need to be linked into the final binary, along with the libraries
they might depend on (in the case of puts, stdio). cmd/link has been
extended to understand basic ELF files, but it does not understand ELF
in the full complexity that modern C libraries embrace, so it cannot
in general generate direct references to the system libraries.
Instead, the build process generates an object file using dynamic
linkage to the desired libraries. The main function is provided by
_cgo_main.c:
int main() { return 0; }
void crosscall2(void(*fn)(void*), void *a, int c, uintptr_t ctxt) { }
uintptr_t _cgo_wait_runtime_init_done(void) { return 0; }
void _cgo_release_context(uintptr_t ctxt) { }
char* _cgo_topofstack(void) { return (char*)0; }
void _cgo_allocate(void *a, int c) { }
void _cgo_panic(void *a, int c) { }
void _cgo_reginit(void) { }
The extra functions here are stubs to satisfy the references in the C
code generated for gcc. The build process links this stub, along with
_cgo_export.c and *.cgo2.c, into a dynamic executable and then lets
cgo examine the executable. Cgo records the list of shared library
references and resolved names and writes them into a new file
_cgo_import.go, which looks like:
//go:cgo_dynamic_linker "/lib64/ld-linux-x86-64.so.2"
//go:cgo_import_dynamic puts puts#GLIBC_2.2.5 "libc.so.6"
//go:cgo_import_dynamic __libc_start_main __libc_start_main#GLIBC_2.2.5 "libc.so.6"
//go:cgo_import_dynamic stdout stdout#GLIBC_2.2.5 "libc.so.6"
//go:cgo_import_dynamic fflush fflush#GLIBC_2.2.5 "libc.so.6"
//go:cgo_import_dynamic _ _ "libpthread.so.0"
//go:cgo_import_dynamic _ _ "libc.so.6"
In the end, the compiled Go package, which will eventually be
presented to cmd/link as part of a larger program, contains:
_go_.o # gc-compiled object for _cgo_gotypes.go, _cgo_import.go, *.cgo1.go
_all.o # gcc-compiled object for _cgo_export.c, *.cgo2.c
If there is an error generating the _cgo_import.go file, then, instead
of adding _cgo_import.go to the package, the go tool adds an empty
file named dynimportfail. The _cgo_import.go file is only needed when
using internal linking mode, which is not the default when linking
programs that use cgo (as described below). If the linker sees a file
named dynimportfail it reports an error if it has been told to use
internal linking mode. This approach is taken because generating
_cgo_import.go requires doing a full C link of the package, which can
fail for reasons that are irrelevant when using external linking mode.
The final program will be a dynamic executable, so that cmd/link can avoid
needing to process arbitrary .o files. It only needs to process the .o
files generated from C files that cgo writes, and those are much more
limited in the ELF or other features that they use.
In essence, the _cgo_import.o file includes the extra linking
directives that cmd/link is not sophisticated enough to derive from _all.o
on its own. Similarly, the _all.o uses dynamic references to real
system object code because cmd/link is not sophisticated enough to process
the real code.
The main benefits of this system are that cmd/link remains relatively simple
(it does not need to implement a complete ELF and Mach-O linker) and
that gcc is not needed after the package is compiled. For example,
package net uses cgo for access to name resolution functions provided
by libc. Although gcc is needed to compile package net, gcc is not
needed to link programs that import package net.
Runtime
When using cgo, Go must not assume that it owns all details of the
process. In particular it needs to coordinate with C in the use of
threads and thread-local storage. The runtime package declares a few
variables:
var (
iscgo bool
_cgo_init unsafe.Pointer
_cgo_thread_start unsafe.Pointer
)
Any package using cgo imports "runtime/cgo", which provides
initializations for these variables. It sets iscgo to true, _cgo_init
to a gcc-compiled function that can be called early during program
startup, and _cgo_thread_start to a gcc-compiled function that can be
used to create a new thread, in place of the runtime's usual direct
system calls.
Internal and External Linking
The text above describes "internal" linking, in which cmd/link parses and
links host object files (ELF, Mach-O, PE, and so on) into the final
executable itself. Keeping cmd/link simple means we cannot possibly
implement the full semantics of the host linker, so the kinds of
objects that can be linked directly into the binary is limited (other
code can only be used as a dynamic library). On the other hand, when
using internal linking, cmd/link can generate Go binaries by itself.
In order to allow linking arbitrary object files without requiring
dynamic libraries, cgo supports an "external" linking mode too. In
external linking mode, cmd/link does not process any host object files.
Instead, it collects all the Go code and writes a single go.o object
file containing it. Then it invokes the host linker (usually gcc) to
combine the go.o object file and any supporting non-Go code into a
final executable. External linking avoids the dynamic library
requirement but introduces a requirement that the host linker be
present to create such a binary.
Most builds both compile source code and invoke the linker to create a
binary. When cgo is involved, the compile step already requires gcc, so
it is not problematic for the link step to require gcc too.
An important exception is builds using a pre-compiled copy of the
standard library. In particular, package net uses cgo on most systems,
and we want to preserve the ability to compile pure Go code that
imports net without requiring gcc to be present at link time. (In this
case, the dynamic library requirement is less significant, because the
only library involved is libc.so, which can usually be assumed
present.)
This conflict between functionality and the gcc requirement means we
must support both internal and external linking, depending on the
circumstances: if net is the only cgo-using package, then internal
linking is probably fine, but if other packages are involved, so that there
are dependencies on libraries beyond libc, external linking is likely
to work better. The compilation of a package records the relevant
information to support both linking modes, leaving the decision
to be made when linking the final binary.
Linking Directives
In either linking mode, package-specific directives must be passed
through to cmd/link. These are communicated by writing //go: directives in a
Go source file compiled by gc. The directives are copied into the .o
object file and then processed by the linker.
The directives are:
//go:cgo_import_dynamic <local> [<remote> ["<library>"]]
In internal linking mode, allow an unresolved reference to
<local>, assuming it will be resolved by a dynamic library
symbol. The optional <remote> specifies the symbol's name and
possibly version in the dynamic library, and the optional "<library>"
names the specific library where the symbol should be found.
On AIX, the library pattern is slightly different. It must be
"lib.a/obj.o" with obj.o the member of this library exporting
this symbol.
In the <remote>, # or @ can be used to introduce a symbol version.
Examples:
//go:cgo_import_dynamic puts
//go:cgo_import_dynamic puts puts#GLIBC_2.2.5
//go:cgo_import_dynamic puts puts#GLIBC_2.2.5 "libc.so.6"
A side effect of the cgo_import_dynamic directive with a
library is to make the final binary depend on that dynamic
library. To get the dependency without importing any specific
symbols, use _ for local and remote.
Example:
//go:cgo_import_dynamic _ _ "libc.so.6"
For compatibility with current versions of SWIG,
#pragma dynimport is an alias for //go:cgo_import_dynamic.
//go:cgo_dynamic_linker "<path>"
In internal linking mode, use "<path>" as the dynamic linker
in the final binary. This directive is only needed from one
package when constructing a binary; by convention it is
supplied by runtime/cgo.
Example:
//go:cgo_dynamic_linker "/lib/ld-linux.so.2"
//go:cgo_export_dynamic <local> <remote>
In internal linking mode, put the Go symbol
named <local> into the program's exported symbol table as
<remote>, so that C code can refer to it by that name. This
mechanism makes it possible for C code to call back into Go or
to share Go's data.
For compatibility with current versions of SWIG,
#pragma dynexport is an alias for //go:cgo_export_dynamic.
//go:cgo_import_static <local>
In external linking mode, allow unresolved references to
<local> in the go.o object file prepared for the host linker,
under the assumption that <local> will be supplied by the
other object files that will be linked with go.o.
Example:
//go:cgo_import_static puts_wrapper
//go:cgo_export_static <local> <remote>
In external linking mode, put the Go symbol
named <local> into the program's exported symbol table as
<remote>, so that C code can refer to it by that name. This
mechanism makes it possible for C code to call back into Go or
to share Go's data.
//go:cgo_ldflag "<arg>"
In external linking mode, invoke the host linker (usually gcc)
with "<arg>" as a command-line argument following the .o files.
Note that the arguments are for "gcc", not "ld".
Example:
//go:cgo_ldflag "-lpthread"
//go:cgo_ldflag "-L/usr/local/sqlite3/lib"
A package compiled with cgo will include directives for both
internal and external linking; the linker will select the appropriate
subset for the chosen linking mode.
Example
As a simple example, consider a package that uses cgo to call C.sin.
The following code will be generated by cgo:
// compiled by gc
//go:cgo_ldflag "-lm"
type _Ctype_double float64
//go:cgo_import_static _cgo_gcc_Cfunc_sin
//go:linkname __cgo_gcc_Cfunc_sin _cgo_gcc_Cfunc_sin
var __cgo_gcc_Cfunc_sin byte
var _cgo_gcc_Cfunc_sin = unsafe.Pointer(&__cgo_gcc_Cfunc_sin)
func _Cfunc_sin(p0 _Ctype_double) (r1 _Ctype_double) {
_cgo_runtime_cgocall(_cgo_gcc_Cfunc_sin, uintptr(unsafe.Pointer(&p0)))
return
}
// compiled by gcc, into foo.cgo2.o
void
_cgo_gcc_Cfunc_sin(void *v)
{
struct {
double p0;
double r;
} __attribute__((__packed__)) *a = v;
a->r = sin(a->p0);
}
What happens at link time depends on whether the final binary is linked
using the internal or external mode. If other packages are compiled in
"external only" mode, then the final link will be an external one.
Otherwise the link will be an internal one.
The linking directives are used according to the kind of final link
used.
In internal mode, cmd/link itself processes all the host object files, in
particular foo.cgo2.o. To do so, it uses the cgo_import_dynamic and
cgo_dynamic_linker directives to learn that the otherwise undefined
reference to sin in foo.cgo2.o should be rewritten to refer to the
symbol sin with version GLIBC_2.2.5 from the dynamic library
"libm.so.6", and the binary should request "/lib/ld-linux.so.2" as its
runtime dynamic linker.
In external mode, cmd/link does not process any host object files, in
particular foo.cgo2.o. It links together the gc-generated object
files, along with any other Go code, into a go.o file. While doing
that, cmd/link will discover that there is no definition for
_cgo_gcc_Cfunc_sin, referred to by the gc-compiled source file. This
is okay, because cmd/link also processes the cgo_import_static directive and
knows that _cgo_gcc_Cfunc_sin is expected to be supplied by a host
object file, so cmd/link does not treat the missing symbol as an error when
creating go.o. Indeed, the definition for _cgo_gcc_Cfunc_sin will be
provided to the host linker by foo2.cgo.o, which in turn will need the
symbol 'sin'. cmd/link also processes the cgo_ldflag directives, so that it
knows that the eventual host link command must include the -lm
argument, so that the host linker will be able to find 'sin' in the
math library.
cmd/link Command Line Interface
The go command and any other Go-aware build systems invoke cmd/link
to link a collection of packages into a single binary. By default, cmd/link will
present the same interface it does today:
cmd/link main.a
produces a file named a.out, even if cmd/link does so by invoking the host
linker in external linking mode.
By default, cmd/link will decide the linking mode as follows: if the only
packages using cgo are those on a list of known standard library
packages (net, os/user, runtime/cgo), cmd/link will use internal linking
mode. Otherwise, there are non-standard cgo packages involved, and cmd/link
will use external linking mode. The first rule means that a build of
the godoc binary, which uses net but no other cgo, can run without
needing gcc available. The second rule means that a build of a
cgo-wrapped library like sqlite3 can generate a standalone executable
instead of needing to refer to a dynamic library. The specific choice
can be overridden using a command line flag: cmd/link -linkmode=internal or
cmd/link -linkmode=external.
In an external link, cmd/link will create a temporary directory, write any
host object files found in package archives to that directory (renamed
to avoid conflicts), write the go.o file to that directory, and invoke
the host linker. The default value for the host linker is $CC, split
into fields, or else "gcc". The specific host linker command line can
be overridden using command line flags: cmd/link -extld=clang
-extldflags='-ggdb -O3'. If any package in a build includes a .cc or
other file compiled by the C++ compiler, the go tool will use the
-extld option to set the host linker to the C++ compiler.
These defaults mean that Go-aware build systems can ignore the linking
changes and keep running plain 'cmd/link' and get reasonable results, but
they can also control the linking details if desired.

// Escape analysis.
//
// Here we analyze functions to determine which Go variables
// (including implicit allocations such as calls to "new" or "make",
// composite literals, etc.) can be allocated on the stack. The two
// key invariants we have to ensure are: (1) pointers to stack objects
// cannot be stored in the heap, and (2) pointers to a stack object
// cannot outlive that object (e.g., because the declaring function
// returned and destroyed the object's stack frame, or its space is
// reused across loop iterations for logically distinct variables).
//
// We implement this with a static data-flow analysis of the AST.
// First, we construct a directed weighted graph where vertices
// (termed "locations") represent variables allocated by statements
// and expressions, and edges represent assignments between variables
// (with weights representing addressing/dereference counts).
//
// Next we walk the graph looking for assignment paths that might
// violate the invariants stated above. If a variable v's address is
// stored in the heap or elsewhere that may outlive it, then v is
// marked as requiring heap allocation.
//
// To support interprocedural analysis, we also record data-flow from
// each function's parameters to the heap and to its result
// parameters. This information is summarized as "parameter tags",
// which are used at static call sites to improve escape analysis of
// function arguments.
// Constructing the location graph.
//
// Every allocating statement (e.g., variable declaration) or
// expression (e.g., "new" or "make") is first mapped to a unique
// "location."
//
// We also model every Go assignment as a directed edges between
// locations. The number of dereference operations minus the number of
// addressing operations is recorded as the edge's weight (termed
// "derefs"). For example:
//
// p = &q // -1
// p = q // 0
// p = *q // 1
// p = **q // 2
//
// p = **&**&q // 2
//
// Note that the & operator can only be applied to addressable
// expressions, and the expression &x itself is not addressable, so
// derefs cannot go below -1.
//
// Every Go language construct is lowered into this representation,
// generally without sensitivity to flow, path, or context; and
// without distinguishing elements within a compound variable. For
// example:
//
// var x struct { f, g *int }
// var u []*int
//
// x.f = u[0]
//
// is modeled simply as
//
// x = *u
//
// That is, we don't distinguish x.f from x.g, or u[0] from u[1],
// u[2], etc. However, we do record the implicit dereference involved
// in indexing a slice.
